2、ed Peter.(2) Peter was helped by John.句(1) helped 是主动态；句(2)was helped 是被动态,可见主动态是无标记的，而被动态是有标记的。构成被动语态由助动词 be 的时态之一和及物动词的过去分词构成。被动语态可用于各种时态，其时态变化通过助动词 be 的不同形式来体现。如：一般现在时的被动态构成形式为助动词 am/is/are + 过去分词；而一般过去时的被动态构成形式为 was/were + 过去分词。本册要掌握的被动语态形式有：一般现在时：am/is/are + 过去分词 e.g. Football is played all ove
3、r the world.Im often asked to do this work. 我常常被派做这项工作。一般过去时：was/were +过去分词 e.g. The terracotta warriors were found in 1974 near Xian.

8、中可能需要这些机器零部件。动词不定式：to be + 过去分词e.g. Im glad to be asked questions.It is impossible for lost time to be made up.失去的时间不可弥补。主要用法被动态常用于下列几种场合：1当不知道或不必提出动作的执行者时（这时都不带由 by 引起的短语） ；Printing was introduced into Europe from China. 印刷术是从中国引入欧洲的。The airplane was made in U.S. Such books are written for children
9、. 这种书是为儿童写的。2. 动作的承受者是谈话的中心（这时可带有由 by 引起的短语） ；The song was composed by a student. 这首歌曲是一个学生谱写的。Thousands of rivers are polluted in the country.3. 出于礼貌措词等原因而不愿说出动作执行者是谁。You are requested to get here in time.请您准时来这儿。带行为主体的被动态行为主体就是动作的执行者，即执行动词所表达的动作的人或物。在被动句中，往往不提及行为主体；但当强调动作的执行者时，可用介词 by 引出行为( by +主体
10、行为主体),置于被动态句的末尾，说明是什么人或物应对有关事件负责。e.g. The village was destroyed by a bomb. 这个村庄毁于炸弹。www. 细节决定未来 5The painting is very valuable.

12、的被动态往往省去助动词 be。e.g. No Chinese spoken here. Shoes repaired.

13、或相互代词时谓语动词用主动语态，不能用被动语态。宾语是同源宾语，不定式、动名词等谓语动词不用被动语态。有些动词以其主动形式表示被动意义，特别是当主语是物时，常见的动词有sell、write 、wash、open、lock 等。（3 ）主动形式表被动意义。当 feel、look、smell、taste、sound 等后面接形容词时；当cut、 read、sell、wear、write 等词带状语修饰语时；当动词表示“开始、结束、关、停、转、启动”等意义时。This kind of cloth washes easily.这种布易洗。These novels wont sell well.这些小说
