(即:客人在他到
2、之前已经离开了。)They had already had breakfast before they arrived at the hotel.(即:吃饭在先,他们到达在后。)注意:在上面两个例句,虽然表达时间的连词不同(when当时;before在前),但两件事发生的先后顺序很明显。请同学们不要被when, before之类的词搞混淆了,关键要抓住两件事情的先后关系。2、表达在过去某个确定的时间之前发生的事或状态。例如:How many English films had you seen by the end of last term ?在这个例句中,没有两个事件作比较。但是,它有一个明
3、确的时间作参考,即last year明确了告诉我们是“过去”时间,而 by the end of last year说的是在last year之前完成的动作,因此它也是“过去的过去”,可以用过去完成时。请同学们仔细阅读下面的例句,注意时间的先后关系和动作的先后顺序:I had finished writing my composition by 10:00 this morning.(今天上午10:00点以前,我已经写完了我的作文。)She had searched the internet for two hours when she found an ad for the Canon di

13、过去时。例如: Peter didnt play football yesterday . ( 彼得昨天没有踢足球。)2、在叙述两件以上的事件时,如果事件之间连接地很紧凑的一系列的动作,一般仍用一般过去时而不用过去完成时。例如: They decided to stay here , and so they built their houses and made their farms . ( 他们决定呆在这儿,所以他们建了房子,开垦了农场。 )三、过去完成的否定句和疑问句1、否定句 had not .例如:I hadnt learnt Lesson 20 yet.2、疑问句 Had.?例如:
14、Had you ever seen such an exciting match before? Yes, I had. / No, I hadnt.四、 一般过去时和过去完成时用法有哪些不同? 1. 在主从复合句中的用法不同 (1) 用在宾语从句中 在主句谓语为一般过去时的宾语从句中,既可用一般过去时,也可用过去完成时。但两种时态的意义明显不同。试比较下列两组句子: She said she was a doctor. 她说她是位医生。(说话时仍为医生) She said she had been a doctor.她说她曾当过医生。(说话时已不是) She said she had bee
15、n a doctor for twenty years.她说她当过20年的医生。(主要强调说话时已当过20年医生,此状态可能已经结束,也可能还没有) 但是,如果从句中有表示具体时间的状语,则常用一般过去时。例如: He said he was born in 1986. 他说他是 1986年出生的。 (2) 用在含有after的主从复合句中 在含有after的主从复合句中,一般在从句中使用过去完成时,主句中使用一般过去时。例如: After he had done his homework, he went out to play football. 因连词after本身能明确表示时间的先后关
16、系,因而多数的主句和从句均使用一般过去时。例如: After he arrived in England, Marx worked hard to improve his English. (3) 用在含有before的主从复合句中 用在含有before的主从复合句中,一般在从句中使用一般过去时,主句中使用过去完成时。例如: Lily had written some letters before she went out shopping. 有时,也可以在从句中用过去完成时,主句中用一般过去时,这样就可使描述更为生动。试比较: We got to the station before the
17、 train had left. 火车尚未开动之前,我们就到了车站。 We had got to the station before the train left. 火车开出之前,我们就已经到了车站。 像after一样, before本身就能明确地表示时间的先后关系,故多数主从句均使用一般过去时,而无需使用过去完成时。例如: Many people left for home before the film ended.电影尚未放完,许多人就起身回家了。 (4) 用在含有when的主从复合句中 由于when本身不能明确表示时间的先后关系,故先发生的动作应用过去完成时,后发生的动作只需用一般过
18、去时。这样用过去完成时的可能是主句,也可能是从句。例如: When all his money had been used up, Peter had to turn to a friend for help. 当他的钱全都用光时,彼得只好转而求助于一个朋友。 有时,主句和从句的谓语动词的先后关系十分明确,两个动作紧接着发生,前一动作导致后一动作,这时两者均用一般过去时即可。例如: When the meeting was over, we left the hall. 散会后,我们就离开了大厅。 2. 叙述几个连续的动作用法不同 在叙述两个或两个以上接连发生的动作用and, but, so或
19、then等连接并按时间发生的先后顺序叙述时,只需用一般过去时。例如: She entered the room, turned on the light and found everything stolen. I lost my pen but soon found it. She lost her pen, so I lent her mine. 但是,如果两个先后发生的动作不是按时间的顺序排列或叙述时,为明确动作发生的先后顺序,先发生的动作就得用过去完成时。例如: The farmers were in high spirits because they had got another
