A new computer has been bought. 2. 含有双宾语的主动句

15、ways kept clean.注意：（1）在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后的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：We often hear him play the guitar. He is often heard to play the guitar. Someone saw a stranger walk into the building. A stranger was seen to walk into the building.（2）

16、带有复合宾语的句子，如果宾语补足语是名词，变被动句时，应将宾语变为主语，不要误把宾语补足语的名词作主语。例：Tomatoes were first taken back to Europe and people called them love apples. Tomatoes were first taken back to Europe and they were called love apples. 即学即用：The monkey was seen _ off the tree. A. jump B. jumps C. jumped D. to jump答案：D 4. 有些相当于及物动

17、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 patient is being operated on. The problem is solved. It neednt be talked about. His request was turned down. The sports meet will be put off because of the bad weather. 即学即用：（1）Older people _ well. A. looks after B. must be looked

The books are taken good care of. Good care is taken of the books. 2）You must pay attention to your pronunciation. A

20、ttention must be paid to your pronunciation. Your pronunciation must be paid attention to. 即学即用：I promise that matter will _.A. be taken good care B. be taken good care of C. take good care D. take good care of 答案：B 6. 当主动句的主语是nobody, no one等含有否定意义的不定代词时，在被动句中将其变为anybody, 作by的宾语，并将谓语动词变为否定的被动语态。例：No

21、body can answer this question. The question can not be answered by anybody. 7. 当否定句中的宾语是anything, anybody, anyone等不定代词时，在被动句中应将其分别变为nothing, nobody, no one作主语，并将谓语动词变为肯定的被动语态。例：They havent done anything to make the river clean.
