Introduction The theme of the enter make-up is The correspond pure(a). The master(prenominal) goal of the work is to identify the principal(prenominal) features of the impersonate hone and to invest the cases of its practice, basing on the theoretical and scientific works of Russian, side of meat linguists. The objectives of the work, in their turn, re interpret ascending steps to the principal(prenominal) goal of the project 1. to give the definition to the evince gross(a) 2. to certify the ways of spurtation of the generate completed separate out 3. to investigate cases of its riding habit in the phrase of faith and in Ameri keister and British slope compargon them 4. o draw the line of demarcation between the use of the indicate completed and the ancient Simple Actuality of the work is the significance of the present perfect decennaryse in the side language. That is a lingual phenomenon, which exists non in e precise language and which is replaced by other tenses while translated into other languages appears to be unity of the main constituents of side of meat grammar. Novelty of the motif lies in communicative approaches to linguistic analysis of the use of the present perfect tense aimed at acquiring the communicative competence.Theoretical value of the composing is based on the analyze data enquiren from the works of American and side prominent linguists. Practical value of the work may be useful in practical grammar or in a daily use. The course paper consists of 4 parts Introduction, Main Part, Conclusion and Bibliography. The Main Part consists of 2 chapters. Thus, Chapter I of the present paper is devoted to the general remarks the present perfect tense and comprises 3 dits 1. annals of the Present gross(a) tense 2.The Formation of the Present accurate 3. Differences between the other(prenominal) In certain(prenominal) and the Present entire In this chapter we can find out general information just about t he origin of perfect tenses and the present perfect tense itself, and the ways of forming the present perfect, and the differences between the one fourth dimension(prenominal)(a) undecomposable and the present perfect in use. Chapter II includes 2 head ups 1. The use of the Present Perfect in the blame 2. Differences in use of the Present Perfect in American and British English.This chapter is devoted to the practical side of the work. We investigate the use of the present perfect in the sentence and the differences of the use of the present perfect in American and British English. Chapter Two can be interesting with the presentation of peculiar characteristics of the use of the present perfect of two main trends of English American and British English. The footing I chose the theme The Present Perfect was the home of not having this tense in the for us familiar languages Russian and Kyrgyz.The Past Simple and The Present Perfect be replaced by hardly one tense in Russian c entirelyed . The nature of this tense seems to be familiar for the learners of English at first sight, just on that point are m all exceptions and particular cases of their use. CHAPTER I What the Present Perfect tense is 1. 1 History of Perfect Tenses and the Present Perfect The Present Perfect is an analytical form which is strengthened up by means of the secondary verb to project in the Present dubious and the participle of the imaginary verb (e. g. I keep back worked. He has worked, etc. The word perfect in the adduce came from a Latin root referring to the theme of completionof creation now finishedrather than to perfection in the star of no flaws (although the latter sense of perfect actu every last( assert)y evolved by extension from the former, because whateverwhatthing for example, a drawing or a piece of pottery is finished when it no ampleer has any flaws). So perfect tenses were named thus because of the idea that (in some uses in some languages, at least) they referred to activitys that were finished with respect to the present (for example, I have eaten all the bread involves a sense of finality).However, as seen above, the name is a misnomer in the sense that not all uses of present perfect constructions involve an idea of completion. In Old English the verb to have, use as the predicate in the sentence, was sometimes followed by direct object with participle II of a transitive verb connect to it on the function of a predicative adjective. The participle agreed in number, gender, case with the direct object. He has that obtain written= . As the state of the object ( written) was the result of the arrant(a) exercise, the spirit of the vocalizer began to be interested in he accomplish. The construction did not show whether the motion expressed by participle II was performed by the field of study of the sentence or by some other agent. It was from constructions where the subject of the sentence was the doer of t he body process denoted by the noncurrent participle, that the modern English perfect form developed. The participle disordered its form of agreement with the noun-object and changing its place (He has written), became closely committed with the verb to have. Both elements lost their independent content and merged into one sense unit the analytical form of the Modern English Perfect.He has written that h elderly in the action of writing is accomplished by him at present and as a result of it the book is in a written state. Thus, what was originally a free syntactical combination has now sullen into an analytical tense form. Such constructions, in which the doer of the action expressed by the participle was not the subject of the sentence, have fluid survived in Modern English as free syntactical combinations He had trinity horses killed under him. I have my dress made here. Killed and made are placid prophetical adjectives to the direct object horses and dress.In constru ction with the verb to be, participle II of an intransitive verb was apply as the predicative to the subject with which agreed in number, gender and case, and the verb to be had the function of a link-verb in a compound-nominal predicate He is ? ecumen = O? . When to have and to be forms turned into perfect, the verb to have began gradually to be apply as an addendum verb with both transitive and intransitive verbs I have seen her. I have throw in. As a selection of the old constriction, to be is still used when the state is stressed May Fielding was already come and so was her baffle. Dickens) When he was kaput(p), my mother asked me all about the day I had had (Dickens)He is gone to the Leas (Bronte) The present perfect is a grammatical combination of the present tense and the perfect aspect, used to express a past event that has present consequences. An example is I have eaten (so Im not hungry). Depending on the special(prenominal) language, the events described by pres ent perfects are not necessarily completed, as in I have been eating or I have lived here for five old age. The present perfect is a compound tense in English, as in some(prenominal) other languages, convey that it is formed by combining an auxiliary verb with the main verb. In modern English, the auxiliary verb for forming the present perfect is always to have. * I have eaten * You have gone * He has arrived In many another(prenominal) other European languages, the equivalent of to have (e. g. , German haben, French avoir) is used to form the present perfect (or their equivalent of the present perfect) for most or all verbs. However, the equivalent of to be (e. g. German sein, French etre) serves as the auxiliary for other verbs in some languages such as German, Dutch, French, and Italian (but not Spanish or Portuguese). Generally, the verbs that take to be as auxiliary are intransitive verbs denoting social movement or change of state (e. g. , to arrive, to go, to fall). In many European languages, including pattern German, French and Italian, the present perfect verb form usually does not convey perfect aspect, but rather perfective aspect. In these languages, it has usurped the component part of the simple past (i. . preterite) in spoken language, and the simple past is now really only used in formal written language and literature. In standard English, Spanish, and Portuguese, by contrast, the present perfect (perfect) and simple past (perfective aspect) are unbroken distinct. The Present Perfect form denotes an action completed originally the present moment (and connected with it) or before a definite moment in the past or future. It is formed by means of the auxiliary verb to have in the required tense and Participle II of the notional verb 1. The formation of the Present Perfect 1. The Present Perfect is formed by means of the Present Indefinite of the auxiliary verb to have and Participle II of the notional verb. 2. In the interrogative for m the auxiliary verb is placed before the subject. In the negative form the negative particle not is placed later the auxiliary verb. Affirmative Interrogative Negative I have workedHe has workedShe has workedWe have workedYou have workedThey have worked rush I worked? Has he worked? Has she worked? Have we worked? Have you worked? Have they worked? I have not workedHe has not workedShe has not workedWe have not workedYou have not workedThey have not worked 3. The contracted affirmative forms are Ive worked Hes worked Youve worked The contracted negative forms are I havent worked He hasnt worked You havent worked 4. The negative-interrogative forms are Has she not worked? Hasnt she worked? Have you not worked? Havent you worked? 1. 3 Differences in between the Past Indefinite and the Present Perfect It follows from the rules above that the Present Perfect is not used when there is an indication of past time in the sentence.It is the Past Indefinite that is used in this case becaus e the mention of the definite past time ties the action to the past- time expanse as it were, and it cannot advanced luck through to the present. e. g. Put on your clothes at once and come with me. tho what is it? Has something happened? Im triskaidekaphobic so. Your husband was taken ill this afternoon. M. Poirot, you have no idea of what I have gone through. I tell apart your wife died adept over a year ago. Similarly, it is the Past Indefinite that is used in questions go intod by when. e. g.When did you actually arrive? When did you change your mind? The Past Indefinite is to a fault used in special questions etymon with where and how when they refer to the past events. The Present Perfect is not common here because the attention in such sentences is drawn to the circumstances of the action rather than to the occurrence itself, which means that the speaker has a definite action in mind. e. g. Where did your uncle receive his guests? Right here. How did he get i n? I asked, and Evans utter, Oh, he has a key. Where is my hat?Where did I leave my hat? check off. The question Where have you been? can be asked of the person who has undecomposed come. e. g. Hello, Mum. Im sorry Im late Where have you been? In all other cases it should be Where were you e. g. Did the party go slay nicely? I dont pick out. I wasnt there. Where were you? In special questions beginning with interrogative words other than those mentioned above (e. g. who, what, why, what for and other), both the Present Perfect and the Past Indefinite are possible. The choice depends on the importation to be conveyed.If address is made to an action which is past or definite in the minds of the people speaking, or if there is a change of scene, the Past In definite is used if reference is made to an action which is still valid as part of the present situation, the Present Perfect should be used. e. g. What have I make against you? she burst out defiantly. Nothing. Th en why cant we get on? I know she gave him a in effect(p) scolding. What did he do? Looking up at her he give tongue to Dorothys gone to a garden party. I know. Why havent you gone excessively? Why didnt you speak to my father yourself on the boat? Note 1. As to general questions, the Present Perfect as well as the Past Indefinite may be found in them because they may inquire either about forward-looking facts which are heavy for the present or about events that are definite in the mind of the speaker. Note 2. In the undermentioned example the verb to be is used in the meaning to visit, to go. Hence it takes the preposition to after it. It is noteworthy that to be acquires this meaning only if used in the Present Perfect or the Past Perfect. e. g.Renny said He has been to Ireland too Have you been to a symphony concert? he continued. Note 3. The combination has/have got may be used as the Present Perfect of the verb to get (which is not very common, though). e. g. I dont know whats got into Steven today. He has got into financial difficulties and needs cash. moreover it is often used as a set phrase which has two different meanings to possess (a) and to be obliged (b). e. g. a) Have you got a telephone? she looked round the room. I dont think weve got any choice, said Francis, ) No he said loudly, there are some risks youve got to take. It doesnt matter what caused it, said Martin. We have got to take the consequences In this case the time reference also changes has/have got is the Present Perfect only in form it actually indicates a present state of things. Note 4. She is gone is a survival of the old Present Perfect which was formed with certain verbs by means of the auxiliary to be. In present-day English it is to be treated as a set phrase meaning she is not here any longer. CHAPTER II The Use of the Present Perfect . 1 The use of the Present Perfect in the condemn The Present Perfect falls within the time sphere of the , present and is not used in narration where reference is made to past events. It follows from that that the Present Perfect is used in present-time contexts, i. e. conversations, newspaper and piano tuner reports, lectures and letters. The Present Perfect has three distinct uses. They ordain be further referred to as Present Perfect I, Present Perfect II and Present Perfect III. 1) Present Perfect I is the Present Perfect proper.It is used to express an accomplished action which is viewed from the moment of speaking as part of the present situation. tending in this case is centred on the action itself. The circumstances under which the action occurred appear unimportant and external at the moment and need not be mentioned. e. g. He is very sensitive, I have ascertained that. Ive had a talk with him. He places he has all the proof he wants. Such news Weve bought a racehorse. Ive spoiled everything, she said. His secretary said tactfully Ive put off your other appoint- ments for a while. It should be oddly noted that though the action expressed in the Present Perfect is regarded as already accomplished, it belongs to the present-time sphere and is treated as a present action. It becomes obvious from the periphrasis Ive heard the doctors opinion I know the doctors opinion. Shes gone off to the woods She is in the woods. A similar idea of an accomplished action is also traced in such expressions referring to the present as He is awake. Im late. The work is done. The door is locked, etc.Since it is the action itself that the Present Perfect makes im- portant, it is frequently used to open up conversations (newspaper and radio reports, or letters) or to introduce a new topic in them. However, if the conversation (report or letter) continues on the same subject, going into detail, the Present Perfect usually changes to the Past Indefinite, as the latter is used to refer to actions or sit- uations which are definite in the mind of the speaker. Usually (but not necessarily) some concrete circumstances of the action (time, place, cause, purpose, manner, etc. are mentioned in this case. e. g. You are all right. You are coming round. Are you feeling better? Im quite all right. except what has happened? Where am I? Youre in a dug-out, You were buried by a bomb from a trench-mortar. Oh, was I? But how did I get here? Someone dragged you. I am afraid some of your men were killed, and several(prenominal)(prenominal) others were wounded. Pussy Cat, Pussy Cat, Where have you been? Ive been to London To look at the Queen. What did you see there? I truism a poor mouse Under her chair. As is seen from the above examples, the Present Perfect is used to name a new action, whereas the Past Indefinite is used to refer back to a definite action and the attention in this case is often drawn rather to the circumstances attending the action than to the action itself. Note. The functions of the Present Perfect and the Past Indefinite may be in a way compared with tho se of the coy and the definite articles. The nebulous article is used when an object is just named (e. g. Glue me a book. She is a teacher. I have a brother).Likewise the Present Perfect serves to name an accomplished action (see the examples above). Both the definite article and the Past Indefinite are used when an object or an action, respectively, is definite in the mind of the speaker (e. g. The book is on the table. The teacher returned the compositions,) As has been said, Present Perfect I is mainly used to introduce a new topic. But it may also be used to sum up a situation. e. g. Ive done bad things, I said, but I dont think I could have done some of the things youve done. Youve so often been friendful in the past. Ive tried, said Joseph. Weve all been young once, you know. Weve all felt it, Roy. Im afraid Ive been horribly boring and talked too more, she said as she pressed my hand. Agatha has told me everything. How cleverly you have both kept your secret, You and you r wife have been very good to me. Thank you. In accordance with its main function just to name an accomplished action the Present Perfect is broadly speaking used when the time of the action is not given. e. g. He sat down. You have not changed, he said. No? What have you come for? To discuss things. Mr has told me such wonderful things about you. Walter. I havent thought about it, she returned. However, sometimes, even though there may be no indication of past time in the sentence, the Present Perfect cannot be used because reference is made to happenings which are definite in the mind of the speaker (either because the action has already been mentioned or because the situation is very well known to the listener). In this case the use of the Past Indefinite is very common. e. g. Did you respite well? I didnt understand you. Did you enjoy the play?Did you have a good journey Did you resembling the book? (trip, ride, flight, day, time)? What did you say? Did you see the accide nt? Did you hear what he said? Im sorry I lost my temper. I didnt hear your question. It is possible, however, to use the Present Perfect when there is an adverbial modifier of time in the sentence that denotes a finale of time which is not over only, e. g. today, this morning time, this week, this month, this year, etc. e. g. What Rosanna has done tonight is seduce enough, (Tonight is not over yet. ) This year we have taken only one assistant. (This year is not over. I have had only one new dress this summer, exclaimed June. (This summer is not over yet. ) Conversely, if the period is over or reference is made to a particular past point of time within that period, the Past Indefinite is used. e. g. Did you see the letter in the Times this morning? (It is no longer morning. ) No. I havent had time to look at a paper today, (Today is not over yet. ) Whom do you think I passed in Richmond Park today (Today is not over, but the action took place at a particular point of time withi n today, namely when the person was in Richmond Park. I wasnt very well this morning, but Im perfectly all right now. (This morning is over. ) Note. It should be noted that sometimes an adverbial modifier of place points to a past period of time. e. g. Did you see him at the theatre? (= when you were at the theatre) I ran into her in Oxford Street. (= when I was in Oxford Street) The Present Perfect may be found with certain adverbs of indefinite time and frequency such as just ( ), not yet, already, before, always, ever, never, often, seldom, recently, late ly, of late, etc. e. g. Shes just helpless being run over.I havent even had coffee yet. He has never made a sixpence by any of his books. Have you heard of him lately? What is the point? Ive made it clear enough before. However, the use of the Present Perfect is by no means obligatory with the above mentioned adverbs, because any other finite form may be used with these adverbs if it is required by the situation. e. g. He w as studying to be a pianist, but he never touches the piano now. He noticed that the leaves of the chestnut were already beginning to turn yellowness and brown. His room was not yet furnished, and he liked it to remain empty. Note 1.Note the use of the Past Indefinite with just now. e. g. I told you just now I had never had time for much fun. Note 2. Russian students of English, under the influence of the Russian language, tend to use the adverb already nearly in every sentence containing the Present Perfect. That is not characteristic of the English language as it is sufficient to use the Present Perfect alone to express an accomplished action. The addition of already appears redundant in many cases. Present Perfect II serves to express an action which began before the moment of speaking and continues into it or up to it.This grammatical meaning is mainly expressed by the Present Perfect Continuous. However, the Present Perfect Non-Continuous is found in the followers cases a)Its use is compulsory with stative verbs. e. g. Ive known the young lady all her life. Ive loved her since she was a child. But weve been in conference for two hours, he said. Its time we had a tea break. b)With some dynamic verbs of durative aspect meaning the Present Perfect is sometimes used instead of the Present Perfect Continuous with little difference in meaning. e. g. Its a pretty room, isnt it? Ive slept in it for fifteen years. Im glad to meet you, he said. Ive waited a long while and began to be afraid Id not have the opportunity. Hes looked after Miss Gregg for many years now. As to terminative verbs, they can only have the meaning of Present Perfect I and never of Present Perfect II. Since it is often difficult to draw the line between durative and terminative verbs, it is recommended that students of English should use the Present Perfect Continuous with all dynamic verbs to express an action begun in the past and continued into the present. )The Present Perfect is pre ferred to the Present Perfect Continuous in negative sentences, when it is the action itself that is completely negated. e. g. Shall we sit down a little? We havent sat here for ages. I was just having a look at the paper, he said. I havent read the paper for the last two days. She hasnt written to me for a year, said Roy. It is noteworthy that Present Perfect II is associated with certain time indications either the whole period of the duration of the action is marked or its starting point.In the former case we find different time indications. Some expressions are introduced by the preposition for and sometimes in (e. g. for an hour, for many years, for the last few days, for a long time, for so long, for ages, in years, in a long while, etc. )- Other expressions have no prepositions (e. g. these three years, all this week, all along, so long, all oneys life, etc. ). e. g. The picture has been mine for years and years. Ive felt otherwise about him for some time. Why havent I see n you all these months? said Hankins.We havent had any fun in a long while. Ive wanted to go to the sea all my life. The starting point of the action is indicated by the adverb since, a prepositional phrase with since or a clause introduced by the conjunction since. e. g. But, Dinny, when did you meet him? Only ten days ago, but Ive seen him every day since. The sun has been in the room since the morning. But she has seemed so much better since you started the injections. In the clause introduced by since the Past Indefinite is used to indicate the starting point of an action.However, we sometimes find in both parts of such complex sentences two parallel actions which began at the same time in the past and continue into the present. In this case the Present Perfect is used in both clauses, e. g. Ive loved you since Ive known you. It should be noted that the indication of time is indispensable to Present Perfect II because otherwise its meaning in most cases would be changed. It w ould come to denote an accomplished action which is part of the present situation. cf. Ive been taught to do it for three years. I have been taught to do it. But we met him here about a month ago.We havent heard from him since. We havent heard from him. Care should be taken to get along between the use of the Present Perfect and the Past Indefinite when the period of duration is expressed by a prepositional phrase with for. If the period of duration belongs to the past time sphere, the Past Indefinite should be used. It is only if the period of duration comes close to the moment of speaking or includes it that the Present Perfect is used. Cf. I have lived like this, he said, for two years, and I cant stand it anymore. I teach History at a secondary school.I went to the University here for four years and got a degree. The same is true of questions beginning with how long. Are you conjoin? Yes. How long have you been married? Are you married? No. Im divorced. How long were yo u married? 3) Present Perfect III is found in adverbial clauses of time introduced by the conjunctions when, before, after, as before long as, till and until where it is used to express a future action. It shows that the action of the subordinate clause will be accomplished before the action of the principal clause (which is usually expressed by the Future Indefinite).This use of the Present Perfect is structurally dependent as it is restricted only to the above mentioned type of clauses. e. g. Youll find, said Fred, that youll long for home when you have left it. As soon as we have had some tea, Ann, we shall go to inspect your house. Ill take you back in my car but not till Ive made you some coffee. Sometimes the Present Indefinite is found in this type of clauses in the same meaning as the Present Perfect. The choice of the form depends on the lexical meaning of the verb. With durative verbs the Present Perfect is necessary. e. g. When you have had your tea, well see about it. I can tell you whether the machine is good or bad when I have tried it. With terminative verbs the use of both forms is possible, Cf. He says when he retires hell grow roses. When Ive finished this I must go and put the baby to bed. Mother will stay at home until we return. Your mother wouldnt like me. You cant possibly say that until youve met her. 2. 2 Differences in Use of the Present Perfect in American and British English In British English the present perfect is used to express an action that has occurred in the recent past that has an effect on the present moment.For example Ive lost my key. groundwork you help me look for it? In American English the pastime is also possible I lost my key. Can you help me look for it? In British English the above would be considered incorrect. However, both forms are generally accepted in standard American English. Other differences involving the use of the present perfect in British English and simple past in American English include alr eady, just and yet. British English Ive just had lunch Ive already seen that film Have you finished your homework yet? American EnglishI just had lunch OR Ive just had lunch Ive already seen that film OR I already saw that film. Have your finished your homework yet? OR Did you finish your homework yet? American English speakers do not use the present perfect for events that are still connected to the present. However, most Americans have a narrower perception of such connections than do other English speakers, particularly the British. For example, the British will say have you had eat this morning, but Americans will often say did you have breakfast this morning. in that respect is no difference in grammar the difference is in the fact that Americans often think of the morning as being past history, whereas the British tend to see breakfast as still being part of the day, at least for a longer time than Americans do. Both groups use the past simple to describe things that they g rok to be unconnected with the present, and both groups use the present perfect to describe things that they grasp to be connected with the present. The difference is in the perception, not the grammar.Some Americans may well use the present perfect, if thats how they perceive the action in question. Conversely, some British speakers may use the past simple, if they think of the action in question as being isolated in the past. The important thing to remember is that, in many expressions, the choice between present perfect and past simple depends solely on what the speaker has in mind. If the speaker perceives something as being completely finished and unconnected to the present, hell use the past simple if he still sees some sort of connection to the present, hell use the present perfect.Two different people talking about the exact same thing may choose to use two different tenses to describe it. There are some cases in which one tense or the other is gramatically necessary, of co urse, but there are many cases in which both are acceptable. If you specify a particular time in the past, for example, you commonly use the past simple (I did it yesterday). And if you say Ive lived here for a year, the implication is that you still live here, whereas if you say I lived here for ayear, the implication is that you no longer live here.Similarly, if a charwoman says Ive had two children, things are going well, but if she says I had two children, it might be a good idea to change the subject. The distinction between present perfect and past simple is difficult to formulate in terms of rules because the rules are quite complex. I usually explain it in terms of the speakers perceptions and via specific examples that illustrate the different ways in which the tenses can be contrasted. If someone says lav went to the movie, it tells me several things. It tells me that John is not with the speaker, for example.It implies that the speaker probably does not expect to enco unter John while he is at the movie. It implies that nothing the speaker is doing right now is connected to Johns trip to the movie. If someone says John has gone to the movie, that, too, tells me several things. It implies that Johns trip to the movie is recent. It implies that something about Johns action is connected to some present state or action in the speakers mind (for example, she may be planning to join him, or she may be describing the reason for his absence in the present, as when answering the telephone).In many cases, the choice between the two is almost arbitrary. In isolation, the present perfect sounds more recent, and/or implies that something may have happened more than once in the past, and implies a connection with the present somehow, but in many contexts these distinctions are unimportant. If someone answers the phone and is asked about John, she will probably say He has gone to the movie, but she might also very well say He went to the movie, particularly if she is American (Americans have a narrower perception of present time than do many other English speakers).Conclusion After investigation of the theme The Present Perfect Tense I came to the endpoint that although the perfect tenses are called as the secondary tenses in the works of Russian scientists Ganshina and Vasilevskaya, it appears to be one of the main and indispensable constituents of the English language tense form. Every action leads to the results. Without results the action is not valuable. So the subject matter of using the perfect tenses is in expressing the results, consequences and the level of accomplishment and duration of the action.The present perfect tense and its use follow the learners of the English language from the first stage of the learning and of a great importance on the same level as the verb to be or there is/ there are constructions. So, on the creation of the theoretical and practical investigation of the use of perfect tenses in the works of pr ominent Russian and English scientists and within American and British fiction conforming to the examined theory, we have reached the following results of the research work The Perfect form denotes an action completed before the present moment (and connected with it) or before a definite moment in the ast or future. It is formed by means of the auxiliary verb to have in the required tense and Participle II of the notional verb. The Present Perfect is used in the following cases 1. The Present Perfect denotes a completed action connected with the present. 2. The Present Perfect is used in adverbial clauses of time after the conjunctions when, till, until, before, after, as soon as to denote an action completed before a definite moment in the future. 3. The Present Perfect denotes an action which began in the past, has been going on up to the present and is still going on.In this case either the starting point of the action is indicated or the whole period of duration. The preposition for is used to denote the whole period of duration. Since is used to indicate the starting point of the action. If the conjunction since introduces a clause, the verb in this clause is in the Past Indefinite. In British English the present perfect is used to express an action that has occurred in the recent past that has an effect on the present moment. For example Ive lost my key.In American English the following is also possible I lost my key. In British English the above would be considered incorrect. However, both forms are generally accepted in standard American English. Other differences involving the use of the present perfect in British English and simple past in American English include already, just and yet. British English Ive just had lunch American English I just had lunch OR Ive just had lunch American English speakers do not use the present perfect for events that are still connected to the present.However, most Americans have a narrower perception of such connection s than do other English speakers, particularly the British.
