主動語態(tài)變被動語態(tài)的方法

3.

被動語態(tài)的時態(tài)

被動語態(tài)的時態(tài)由被動結構“be+過去分詞”中的動詞be來體現(xiàn)，其基本結構和用法

(1) 一般現(xiàn)在時的被動語態(tài)：am [is, are]+過去分詞

English is taught in our school. 我們學校學英語。

We are taken good care of at school. 我們在學校受到很好的照顧。

(2) 一般過去時的被動語態(tài)：was [were]+過去分詞

He was taken to the police station. 他被帶到了警察局。

The house was built ten years ago. 這座房子是10年前建的。

(3) 一般將來時的被動語態(tài)：will be+過去分詞

A new building will be built here soon. 不久這里將建一棟新樓。

The meeting will be held at two this afternoon. 會議將于今天下午2點舉行。

(4) 現(xiàn)在完成時的被動語態(tài)：have [has]been+過去分詞

All the work has been done now. 所有的工作現(xiàn)在都做好了。

Have the letters been posted? 信都寄了嗎？

(5) 過去完成時的被動語態(tài)：had been+過去分詞

He told me that a new station was being built. 他說正在修建一個新車站。

(8) 過去將來時的被動語態(tài)：would be+過去分詞

含有情態(tài)動詞的被動形式

若主動語態(tài)中謂語含有情態(tài)動詞，在相應的被動語態(tài)中通常應保留該情態(tài)動詞，其結構為“情態(tài)動詞+be+過去分詞”

Everyone must know this. →This must be known by everyone.

請看以下帶情態(tài)動詞被動句實例：

This can’t be done in a short time. 這不是短期內(nèi)可以完成的。

Can this be done by machine? 這可以由機器來做嗎?

The work must be done at once. 這工作必須馬上做了。
