動詞的時態和語態
在接下來的時間里將給大家介紹一下動詞的時態和語態。
到目前為止大家應該知道,動詞共有16種時態和兩種語態。
在時態方面,考題中主要涉及到其中的10種:一般現在時、一般過去時、一般將來時、現在進行時、現在完成時、過去將來時、過去進行時、過去完成時、將來進行時、將來完成時、現在完成進行時。
1. 一般現在時:通常有六種用法,其中最重要的考點是:在時間或條件狀語從句中表示將來的動作;安排或計劃好的將來發生的動作。
如:1>. the train for shanghai leaves at 11a.m and arrives at 11p.m.
2>. as soon as the manager comes back, i will tell him about it.
2. 一般過去時: 關于該時態最主要請大家掌握它的概念:一個開始于過去結束于過去的動作,或存在的狀態。記住這一點很重要,需要與現在完成時區分。
如:the other day she ran across an old friend in the street.
3. 一般將來時: 除了用will + 動詞原形表示該時態外,還有:
1> be going to do sth: she is going to go abroad next year.
2> be about to do sth: please fasten your safety belt, for the plane is about to take off.
3> be to do sth: there is to be a class meeting this afternoon.
4. 現在進行時: 除了眾所周知的表正在進行動作外,還有如下特殊用法:
預計一個將要發生的動作;常與某些副詞連用,表示某種感情色彩,如贊嘆、驚訝或不滿。
如:1> how many of you are going to the party tonight.
2> the teacher is always criticizing us.
5. 現在完成時:這應該是五個基本時態中最令大家迷惑的一個。該時態分為已完成和未完成兩種。常見的標志性的詞有:since, for, already, so far, up to now, in the last few years, in the past three months etc.
如:1> he has lived here since he got married.
2> in the past two decades, research has expanded our knowledge about sleep and dreams.
3> in the last ten years great changes have taken place in china.
6. 過去將來時:只有一個考點:用于主句的謂語動詞是過去時態的間接引語中,遵循時態呼應原則。
如:she said she would pay us a visit when she had enough time.
7. 過去進行時:表示在過去的某個時刻發生的動作或某段時間內一直進行的動作。
如:1> at nine o’clock last night, i was counting the stars in the sky.
2> when the girl came in, the two dogs were fighting for a bone.
3> while i was preparing for the exam, the power was cut off.
8. 過去完成時:別名“過去的過去。”考題中對該時態的使用有要求,只有當句中有一個動作是過去時,才有可能用過去完成。
如:1> the film had almost finished when i got to the cinema.
2> by the time he was ten, he had built himself a chemistry lab.
