He often tells us interesting stories . (主动
7、语态) (被动语态)常带双宾语的词有:tell , show , lend , pass等。2. 在主动语态中,某些动词之后带有复合宾语,即宾语和宾语补足语,这个复合宾语由动词不定式来充当,to被省略,但在被动语态中,这个to还要还原。eg. I often hear her sing this popular song . (主动语态) She is often heard to sing this popular song .(被动语态) 有这种用法的常用动词有:make , let , see , hear , watch , feel , notice等。3. 有些“be +过去分词”
8、的结构并不是被动语态,它们有可能是“系表结构(即系动词之后由过去分词来充当表语)。”比较:(1)(2)4. 只有及物动词和可有宾语的动词+介词词组才可以有被动语态。eg. 【总结】一、被动语态的构成形式1. 被动语态的基本时态变化被动语态通常为十种时态的被动形式, 被动语态由be过去分词构成,be随时态的变化而变化。以do为例,各种时态的被动语态形式为: 1) am/is/are +done (过去分词) 一般现在时例Visitors are requested not to touch the exhibits.2) has /have been done 现在完成时例All the pre
9、parations for the task have been completed, and were ready to start.3) am/is /are being done 现在进行时例A new cinema is being built here4) was/were done 一般过去时例I was given ten minutes to decide whether I should reject the offer.5) had been done 过去完成时例 By the end of last year, another new gymnasium had bee
10、n completed in Beijing.6) was/were being done 过去进行时例A meeting was being held when I was there.7) shall/will be done 一般将来时例Hundreds of jobs will be lost if the factory closes.8) should/would be done 过去将来时例The news would be sent to the soldiers mother as soon as it arrived.9) shall/will have been done
11、 将来完成时(少用)例The project will have been completed before July.2. 被动语态的特殊结构形式1)带情态动词的被动结构。其形式为:情态动词be过去分词。例The baby should be taken good care of by the baby-sitter.2) 有些动词可以有两个宾语,在用于被动结构时,可以把主动结构中的一个宾语变为主语,另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。例His mother gave him a present for his birthday. 可改为 He was given a pr
12、esent by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时,将宾语变为被动结构中的主语,其余不动。例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.4)在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时,在主动结构中不定式to要省略,但变为被动结构时,要加to。例Someone saw a strang
13、er walk into the building. 可改为A stranger was seen to walk into the building.5) 有些相当于及物动词的动词词组,如“动词介词”,“动词副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开。其中的介词或副词也不能省略。例The meeting is to be put off till Friday.3. 非谓语动词的被动语态v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。例I dont like being laughed at in the public.二、 如何使用被动语态
14、学习被动语态时,不仅要知道被动语态的各种语法结构,还要知道在哪些情况中使用被动语态。1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。例 My bike was stolen last night.2. 借助被动的动作突出动作的执行者。例 I was given ten minutes to decide whether I should accept the offer.3. 为了更好地安排句子。例The well-known person got on the bus and was immediately recognized by people. (一个主语就够了)三、 It is said that+从句及其他类似句型一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“Itbe过去分词that从句”或“主语b
