3. 常用的时间状语: just then(那时), at this time yesterday, yesterday afternoon, at that time, this morning, the whole morning, the whole morning, all day yesterday, from nine to ten last evening, those days或以when, while引导的谓语动词是一般过去时的时间状语等。
否定句则在was/were后加一个not,疑问句将was/were提前则可。
如:He was reading a book at 5:00pm yesterday.→He was not reading a book at 5:00 yesterday.→Was he reading a book at 5:00 yesterday? (Yes, he was./ No, he wasn’t.)→What was he doing at 5:00 yesterday?5.1时,只表示有过这件事;用过去进行时,则强调动作的连续性。
①I wrote a letter this morning. 今天上午我写了一封信。
(信写完了)I was writing a letter this morning. 今天上午我在写一封信。
(信不一定写完)②The children watched TV yesterday evening. 昨天晚上孩子们看了电视。
(强调过去发生了这件事)The children were watching TV yesterday evening. 昨晚孩子们都在看电视。
(强调昨晚看电视这一动作的持续性)6.when和while的区别:他们作从属连词时都有“当……. 时候”之意,用法稍有不同:①when引导的时间状语从句的谓语动词可以是短暂性动词,也可以是延续性动词,而while引导的时间状语从句中的谓语动词只能是延续性动词。
②when引导的从句谓语动词如果是短暂性动词则用一般过去时,主句是延续性动词则用过去进行时,从句动作发生在主句动作的时间段之内(长动作用过去进行时,短动作用一般过去时);如果主句和从句两个谓语动词都是延续性动词则全部用过去进行时,这时when和while都可以用。
③when从句的谓语动词可以在主句谓语动作之前、之后或同时发生;while和as从句的谓语动作必须是和主句谓语动作同时发生。
④when和while两个词还可以用作并列连词,但意思不同,when相当于“在那时”,等于at that time或just then;而while but,表示对比关系。
(这一点暂时可以不掌握)eg.⑴ I was playing computer games when my father got home.(2) Mother was cooking when/while I was doing my homework.= When/While I was doing my homework, mother was cooking.六、现在完成时1. 用法1:表示:过去发生或已经完成的某一动作对现在造成的影响或结果。
标志词:already, yet, just, ever, never, before2. 用法2:表示:过去已经开始,持续到现在的动作或状态。
标志词:for, since, since…ago3. 注意:非延续性动词不能用“现在完成时+ 表示一段时间的状语”的句型中。
这类动词有:come, go, start, leave, die, buy, finish, join, borrow, stop等。
但它们能够用表示持续状态的相应的延续性动词替换句中的非延续性性动词。
例如:arrive, come →be here, be in buy →have begin, start →be on ;die →be dead finish, end →be over go out →be outjoin →be in borrow→keep finish/end →be overclose →be closed leave, move →be away; fall asleep →be asleep5.比较过去时与现在完成时1)过去时常与具体的时间状语连用,而现在完成时通常与模糊的时间状语连用,或无时间状语。
一般过去时的时间状语:yesterday, last week,…ago, in1980, in October, just now, 具体的时间状语现在完成时的时间状语for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always,3)现在完成时可表示持续到现在的动作或状态,动词一般是延续性的,如live, teach, learn, work, study, know. 过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。
