人教版九年级被动语态的用法

9.1被动语态的专项习题 1.英语动词有两种语态，即主动语态和被动语态。当主语为动作的执行者时，谓语的形式为主动语态；当主语为动作的承受者时，谓语要用被动语态。例如： English is spoken by many people. The telephone was invented by Bell in 1876. 2.被动语态由“助动词be+及物动词的过去分词”构成。 肯定式 否定式 疑问式 一般现在时 I am asked.... He/ She is asked.... I am not asked.... He/ She is not asked.. Am I asked....? Is he/she asked....? 一般过去时 I was asked.... He/ She was asked.... I was not asked.... He/She was not asked.. Was I asked....? Was he/she asked....? 3.含有情态动词的被动语态由“情态动词+ be+及物动词的过去分词”构成。 Teenagers should be allowed to make their own decisions. 4.当我们不知道谁是动作的执行者，或者没有必要说明谁是动作的执行者、或者只需要强调动作的承受者时，要用被动语态。 The blouse is made of silk. The zipper is often used in our daily lives. 一、选择题 1._________ a new library _________ in our school last year?  A. Is; built          B. Was; built      C. Does; build     D. Did  build  2. An accident________on this road last week.  A. has been happened   B. was happened   C. is happened     D. happene
