6. 语态转换时应注意的问题：

1） 把主动语态变为被动语态时，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。

→A new computer has been bought. (正确)

如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说

→A present was given to me yesterday.

一个礼物昨天被给了我。

3） 由动词+ 介词或副词构成的短语动词，要把它们作为整体看，即把它们看成一个及物动词，介词或副词不可拆开或漏掉。

→We were told to follow her instructions.

→He is often heard to play the guitar.

5）当主动句的主语是nobody, no one等含有否定意义的不定代词时，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。

误：The question can be answered by nobody.

正：The question can not be answered by anybody.

6）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。

7）以who为主语开头的疑问句，变被动时，用by whom放在句首。

误：Who was the story written?

8）有些动词既是及物又是不及物，当它们和well, badly, easily等副词连用时，表示主语内在品质或性能，是不及物动词，用主动表示被动，这时不用被动语态，常见的有：write, read, clean, sell, wash, cook 等。
