主动语态变被动语态需要注意的几个问题.
（1）时态保持一致。I have repaired my computer.---My computer has been repaired.
（2）谓语为动词短语的被动语态不能丢掉动词短语的介词或副词。
His best friend often looks after him.--He is often looked after by his best friend.
3) 主动语态中若有双宾语,将其中一个宾语变为被动句的主语,另一个宾语不变。
动词make/buy//get用for;动词give//send/lend/take用to)
Vivian gave me a book. (双宾语，人间物直， me为间接宾语，a book 为直接宾语)
-- I was given a book by Vivian.
--A book was given to me by Vivian.（直接宾语提前时，要在间接宾语前加介词）
（4）主动语态若有复合宾语，（即句子结构为主＋及物动词＋宾＋宾补），将主动句的宾语变为被动句的主语，宾补不变。 They call him Louis. --He is called Louis.
（5）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.
6) 主动语态句中动词make, have, let(使sb做sth), notice. see. watch, look at, hear, listen to, feel等变成被动语态时，后面的不定式需要加上to.
Mr. Lee made him wash the dishes. --He was made to wash the dishes.
（7）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.
（8）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 don't like being laughed at in the public.
（9）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“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。有：
It is said that… 据说,
It is reported that…据报道，
It is believed that…大家相信，
It is hoped that…大家希望，
It is well known that…众所周知，
It is thought that…大家认为，
It is suggested that…据建议。
例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ）
