初中英語時(shí)態(tài)講解練習(xí)

1、初中英語時(shí)態(tài)綜合講解訓(xùn)練學(xué)習(xí)英語時(shí)態(tài)的意義：英漢兩種語言在時(shí)態(tài)表達(dá)方式上有很大的差異：如，“他經(jīng)常幫助我?！薄八蛱鞄椭伊?。”和“他一直在幫助我?！边@三句話當(dāng)中，漢語的動(dòng)詞“幫助”沒有任何變化，而是用“經(jīng)?！?、“一直”和“昨天”分別表達(dá)出時(shí)間的區(qū)別。英語就不同，它必須用動(dòng)詞本身的形態(tài)變化來完成任務(wù)。 He often helps me. 他經(jīng)常幫助我。 He helped me yesterday. 他昨天幫助我了。 He has been helping me. 他一直在幫助我。在這幾句中，動(dòng)詞help的意義沒有變化，但形態(tài)變了.我們初中英語需要掌握多少個(gè)時(shí)態(tài)呢？一 初中英語常見的八種時(shí)態(tài)

17、續(xù)性動(dòng)詞. 例如：When the fire broke out, all the students were sleeping quietly. (只能用when) While I was doing my homework, the telephone rang. (when和while可以互換)當(dāng)兩個(gè)表示時(shí)間延續(xù)的動(dòng)作同時(shí)發(fā)生而有具有對比意味時(shí)，用while，在這樣的復(fù)合句中，主，從句的時(shí)態(tài)通常是相同的。 例如： Father was repairing a report while I was playing PC games. while更強(qiáng)調(diào)兩個(gè)動(dòng)作同時(shí)進(jìn)行。 要表達(dá)轉(zhuǎn)折“而，卻”

20、o, in1980, in October, just now等，皆為具體的時(shí)間狀語。 現(xiàn)在完成時(shí)的時(shí)間狀語：for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等，皆不確定的時(shí)間狀語。 共同的時(shí)間狀語：this morning, tonight, this April, now, already, recently, lately 等。 3) 現(xiàn)在完成時(shí)可表示持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)，動(dòng)詞一般是延續(xù)性的，如live, teach, learn, wor

31、。 （表結(jié)果） I've known him since then. 我從那時(shí)起就認(rèn)識(shí)他了。（表經(jīng)歷） 2） 用于till / until從句的差異 延續(xù)動(dòng)詞用于肯定句，表示"做直到" 瞬間動(dòng)詞用于否定句， 表示"到，才"。例如： He didn't come back until ten o'clock. 他到10 點(diǎn)才回來。 He slept until ten o'clock. 他一直睡到10點(diǎn)。 典型例題 1.

32、times. A. had met B. have met C. met D. meet 答案B.  首先本題后句強(qiáng)調(diào)對現(xiàn)在的影響，我知道她的模樣，你不用描述。再次，several times告知為反復(fù)發(fā)生的動(dòng)作，因此用現(xiàn)在完成時(shí)。 2. -I'm sorry to keep you waiting. -Oh, not at all. I _here only a few minutes. A. have been B. had been C. was D. will be 答案A.  等待的動(dòng)作由過去開始，持續(xù)到現(xiàn)在，應(yīng)用現(xiàn)在完成時(shí)。 常見的終止性動(dòng)詞要接一段時(shí)間
