英語語法中的過去完成時和現(xiàn)在完成時的區(qū)別
句話強(qiáng)調(diào)的是過去的經(jīng)歷對現(xiàn)在的影響,即我有北京的旅行經(jīng)歷。 而當(dāng)我們需要強(qiáng)調(diào)過去某個時間之前已經(jīng)完成的動作或事件時,可以使用過去完成時。例如,"She had finished her work before she went to bed."(她睡覺之前已經(jīng)完成了工作。)這句話強(qiáng)調(diào)的是在她睡覺之前已經(jīng)完成了工作這一過去發(fā)生的動作。 需要注意的是,這兩種時態(tài)都與過去有關(guān),但在時間關(guān)系和語義上有所區(qū)別。因此,在學(xué)習(xí)和運用時,我們應(yīng)該注意上下文和語境,并選擇合適的時態(tài)來表達(dá)自己的意思。 通過掌握現(xiàn)在完成時和過去完成時的用法和區(qū)別,小學(xué)生們可以更準(zhǔn)確地現(xiàn)在完成時(Present Perfect)和過去完成時表達(dá)過去的經(jīng)歷、動作和事件,并理解他人對過去的描述。在學(xué)習(xí)過程中,可以結(jié)合練習(xí)題和閱讀材料,提升對這兩種時態(tài)的理解和運用能力。 如果您對英語學(xué)習(xí)感興趣,想要深入學(xué)習(xí),可以了解滬江網(wǎng)校精品課程,量身定制高效實用的個性化學(xué)習(xí)方案,專屬督導(dǎo)全程伴學(xué)。掃一掃領(lǐng)200暢學(xué)卡

將來完成進(jìn)行時的情態(tài)意義
行時。如: I’ll have finished in the bathroom in a few minutes.?我一會兒就用完浴室了。 As soon as I have finished I’ll give you a call.?我一完事兒,就給你打電話。 ? 三、將來完成進(jìn)行時與將來完成時比較 將來完成進(jìn)行時與將來完成時的關(guān)系和現(xiàn)在完成進(jìn)行時與現(xiàn)在完成時的關(guān)系一樣。即在以下情況下可以用將來完成進(jìn)行時而不用將來完成時: 1.?動作本身就是連續(xù)的: By the end of the month he will have been living / working / studying here for ten years.?到了月底他在這里居住?/?工作?/?學(xué)習(xí)就滿十年了。 2.?一種經(jīng)常進(jìn)行的動作被表示為連續(xù)的動作: By the end of this month he will have been training horses / climbing mountains for twenty years.?到了這個月底他馴馬?/?登山就滿?20年了。 但是如果提到所馴馬匹或所攀登的山峰的數(shù)目,或用任何方式把動作分割為一次又一次的動作,就必須用將來完成時: By the end of the month he will have trained 600 horses / climbed 50 mountains.?到本月底,他馴服的馬就有600匹?/?攀登的山峰就有50座了。 ? 怎么樣,看完成進(jìn)行時是英語時態(tài)中比較常見的一種,但是,大家對它的用法可能還是不太了解。今天,小編為大家準(zhǔn)備了相關(guān)的語法知識,將要為大家來講解一下:將來完成進(jìn)行時的概念和用法,一起來看看吧! ? 一、將來完成進(jìn)行時的情態(tài)意義 “will / shall have been+現(xiàn)在分詞”結(jié)構(gòu)除表示將來完成進(jìn)行時外,有時其中的?will?也可能是情態(tài)動詞,具有情態(tài)意義,比較表示推測或猜想等。如: They will have been having a holiday yesterday.?他們昨天大概是在度假。 You’ll have been wondering all this time how my invention works.?我想你這些時候一直想知道我的發(fā)明怎樣會行得通的。 ? 二、將來完成進(jìn)行時用于狀語從句的變體 正如我們通常要在條件狀語從句和時時間狀語從句中用一般現(xiàn)在時代替一般將來時以及用現(xiàn)在完成時代替將來完成時等一樣,如果因語義的需要,我們需要在條件狀語從句和時時間狀語從句中使用將來完成進(jìn)行時,那么我們通常要用現(xiàn)在完成進(jìn)行時代替將來完成進(jìn)行時。如: I’ll have finished in the bathroom in a few minutes.?我一會兒就用完浴室了。 As soon as I have finished I’ll give you a call.?我一完事兒,就給你打電話。 ? 三、將來完成進(jìn)行時與將來完成時比較 將來完成進(jìn)行時與將來完成時的關(guān)系和現(xiàn)在完成進(jìn)行時與現(xiàn)在完成時的關(guān)系一樣。即在以下情況下可以用將來完成進(jìn)行時而不用將來完成時: 1.?動作本身就是連續(xù)的: By the end of the month he will have been living / working / studying here for ten years.?到了月底他在這里居住?/?工作?/?學(xué)習(xí)就滿十年了。 2.?一種經(jīng)常進(jìn)行的動作被表示為連續(xù)的動作: By the end of this month he will have been training horses / climbing mountains for twenty years.?到了這個月底他馴馬?/?登山就滿?20年了。 但是如果提到所馴馬匹或所攀登的山峰的數(shù)目,或用任何方式把動作分割為一次又一次的動作,就必須用將來完成時: By the end of the month he will have trained 600 horses / climbed 50 mountains.?到本月底,他馴服的馬就有600匹?/?攀登的山峰就有50座了。 ? 怎么樣,看完了這篇文章,大家是不是對將來完成進(jìn)行時的用法有了初步的了解了呢?喜歡就趕快收藏起來吧~

語法:過去完成進(jìn)行時的形式
別的含義: 1)尚未完成: He had been writing the novel.(He had not finished it yet.) 2)企圖: He had been studying the meaning of this proverb.(He was trying to study it.) 3)未得結(jié)果: We had been studying what our enemy had said.(But we were not able to understand it.) 4)最近情況: He had been quarrelling with his wife.(lately) 5)反復(fù)動作: He had been asking me the same question.(Many times) 6)情緒: What had he been doing?(不耐煩) 這個時態(tài)很少用在否定句中,而多以過去完成時代替: He had not practised English for many years.(普通說法) He had not been practising English for many years.(少見) 這個時態(tài)還可用在said,supposed等引起的間接引語中,代替現(xiàn)在完成進(jìn)完成進(jìn)行時行時: He said,“I have been speaking to John.”= He said that he had been speaking to John. He thought,“She was watching me when I passed.”= He thought that she had been watching him when he had passed.? ? 怎么樣,看完了小編給大家準(zhǔn)備的語法知識,有沒有感覺收獲頗多呢?喜歡就收藏起來吧~

過去完成進(jìn)行時的時態(tài)特點
行時的用法 A. 在某段時間內(nèi)一直進(jìn)行的動作用現(xiàn)在完成進(jìn)行時來強(qiáng)調(diào)動作在某段時間里的持續(xù)性動作通常有"現(xiàn)在"的結(jié)果要根據(jù)上下文來確定到"現(xiàn)在"為止動作是否還在繼續(xù)進(jìn)行同樣過去完成進(jìn)行時表示在過去更早時間內(nèi)進(jìn)行的動作,并對過去某一時刻產(chǎn)生結(jié)果。 B.表示重復(fù)動作的現(xiàn)在/過去完成進(jìn)行時 我們也可以用完成進(jìn)完成時代替,例如: He had not practiced English for many years 他沒有練習(xí)英語很多年了。(普通說法) He had not been practicing English for many years. 很多年了,他一直沒有練習(xí)英語。(少見) 二、這種時態(tài)還可用在said,supposed等引起的間接引語中代替現(xiàn)在完成進(jìn)行時 He said“I have been speaking to John”= He said that he had been speaking to John 他說“我一直和約翰說著話”。 He thought“She was watching me when I passed”= He thought that she had been watching him when he had passed 他想“當(dāng)我經(jīng)過的時候,她正看著我”。 三、過去完成進(jìn)行時經(jīng)常與現(xiàn)在完成進(jìn)行時混淆。 現(xiàn)在完成進(jìn)行時 (The present perfect progressive) 由 have/has been +-分詞構(gòu)成 過去完成進(jìn)行時 The past perfect progressive tenses 由 had been +-分詞構(gòu)成 四、現(xiàn)在/過去完成進(jìn)行時的用法 A. 在某段時間內(nèi)一直進(jìn)行的動作用現(xiàn)在完成進(jìn)行時來強(qiáng)調(diào)動作在某段時間里的持續(xù)性動作通常有"現(xiàn)在"的結(jié)果要根據(jù)上下文來確定到"現(xiàn)在"為止動作是否還在繼續(xù)進(jìn)行同樣過去完成進(jìn)行時表示在過去更早時間內(nèi)進(jìn)行的動作,并對過去某一時刻產(chǎn)生結(jié)果。 B.表示重復(fù)動作的現(xiàn)在/過去完成進(jìn)行時 我們也可以用完成進(jìn)行時形式來表示現(xiàn)在或過去經(jīng)常重復(fù)的動作。 注意過去完成進(jìn)行時和過去完成時類似需要有過去這一時間點。
