英語(yǔ)中有一種主動(dòng)句可以轉(zhuǎn)換成兩種被動(dòng)句型，它們通常是一些表示客觀說(shuō)明的句子，如：

　　People believed that she is honest. 大家相信她是誠(chéng)實(shí)的。www.51jjcn.cn/yfdq/3123.html

　　→ It’s believed that she is honest. 大家相信她是誠(chéng)實(shí)的。

　　→ She is believed to be honest. 大家相信她是誠(chéng)實(shí)的。

　　比較上面兩類被動(dòng)句型可以發(fā)現(xiàn)，一類是“it+be+過(guò)去分詞+that從句”，另一類則是“主語(yǔ)+be+過(guò)去分詞+不定式”(其中的“主語(yǔ)”為前一類句型中that從句中的主語(yǔ))，通常可用于這兩類被動(dòng)句型的動(dòng)詞有assume, believe, expect, fear, feel, know, presume, report, say, suppose, think, understand等，比較(同時(shí)注意其中時(shí)態(tài)和動(dòng)詞形式的變化)：

　　It’s expected that he will come soon.= He is expected to come soon. 預(yù)計(jì)他很快就會(huì)來(lái)。

　　It’s expected that he has come. =He is expected to have come. 估計(jì)他會(huì)已經(jīng)來(lái)了。

　　It’s known that is a good singer. =He is known to be a good singer. 大家知道他是位優(yōu)秀的歌手。

　　It’s known that was a good singer. =He is known to have been a good singer. 大家知道他曾是位優(yōu)秀的歌手。
