①I had mended the TV set before my brother returned.我兄弟回来之前我修好了电视机。
②I didn't go to the movie“The Gold Rush”because I had seen it twice.
我没去看电影“淘金热”，因为这部片子我已看过两遍。
3）在含有宾语从句的复合句中当主句谓语动同为said，asked，answered等时，从句谓语动词表示在这以前完成的动作，要用过去完成时。如：
①I remembered that I went out after I had closed the door.我记得自己是在关上门后才出去的。
4）表示过去某一时刻延续到过去另一时刻的动作或状态，常和for构成的介词短语以及since构成的介词短语或时间状语从句连用。如：
①Mr Smith had lived there alone（for）two years.史密斯先生独自在那儿居住两年。
被动语态的复习
有关被动语态的几种基本句型，这里就不赘述了，在此说明被动语态需注意的几点：
1.动词feel, look, smell, sound, taste, cut, open, read, sell, shut, wear, write 等的主动形式表示被动含义。
The book written by that famous writer is selling very well.
那些名作家写的书非常畅销。（实际是“被”卖的）
2.动词need, want, require 后的动名词的主动形式表示被动含义。如：
These flowers need / want / require watering. (含“被”浇水)这些花需要浇水。
be worth后的动名词的主动形式表示被动含义。
This book is well worth reading.这本书值得一读。（实际是“被”读）
3.一些动词的宾语补足语，主动式时不用to, 被动式要带to。这些动词有feel, smell, see, notice。watch, hear, taste, have, make等。如：
People often saw him enter that shop.人们经常看见他进入那个商店。
4.作及物动词用的短语动词的被动语态须保持其完整性。
(1) 动词+介词
We must send for the doctor at once.----The doctor must be sent for at once.
必须立即派人去请医生
（2）动词+名词+介词
They are taking good care of the children.----The children are being taken good care of by them
孩子们正受他们很好的照顾。
(3)动词+副词+介词
People looked down upon women in the past. Women were looked down upon by people in the past. 过去妇女被人瞧不起（轻视）。
语法练习
1. ( 1998NMET>Shirley ________ a book about China last year but I don't know whether she has finished it.
A. has written B. wrote C. had written D. was writing
分析：考查进行时态的特性之一——未完成性。从题干but I don’t know whether she has finished it这一信息句可知，该题应填过去进行时，表明去年Shirley写着一本关于中国的书，该书没写完，A、C项时态与本句所用的时间状语不符，B项表明书已在去年写完，与本文不符，故排除。答案是D。
2. (1996NMET) Helen ________ her keys in the office so she had to wait until her husband ________ home.
A. has left, comes B. left, had come
C. had left, came D. had left, would come
分析：句意是“海伦不得不等她丈夫回家，因为她将钥匙忘在办公室了”。很显然，leave 的动作发生在的wait之前，应用过去完成时；而第二分句中的主句为一般过去时，其从句是时间状语从句也应用过去时。答案为C。
3. (1995NMET)—_______ the sports meet might be put off.
—Yes, it all depends on the weather.
A. I've been told B. I've told C. I'm told D.I told
分析：从it all depends on the weather 一句的时态和所告知的内容可以断定，应该用现在完成时的被动形式。答案为A。
4. (1998NMET)My brother ________ while he ________ his bicycle and hurt himself.
A. fell, was riding B. fell, were riding
C. had fallen, road D. had fallen, was riding
分析：while he was riding his bicycle 表示在My brother 正骑自行车的时候，即动作的一瞬间。该题的and hurt himself 具有一定的迷惑性。有学生把hurt and rode 当成并列成分而误选C为正确答案。而实际上hurt 同fell才是并列关系。答案为A。
