一、主动语态如何变被动语态

宾变主, 主变宾, by短语后面跟。

谓语动词变被动, be后“过分”来使用。

We have bought a personal computer recently.

A personal computer has been bought by us recently. Europe has invented a wrist-worn PC recently. A wrist-worn PC has been invented in Europe recently. A Chinese scientist has already developed

A pen-like computer. A pen-like computer has already been developed by a Chinese scientist. The earthquake has killed many people . Many people have been killed by the earthquake

Step 4 Deductive and Inductive 总结归纳

现在完成时的被动语态应注意的问题（让学生先发现问题，再得出结论）

[误] Such a man has been hardly believed. [正] Such a man has hardly been believed.

1. 副词的位置

often, usually, always, never, hardly, seldom等副词置于have/has和been

中间。

[误]A big earthquake was happened in Wenchuan. [正] A big earthquake happened in Wenchuan. 2. 并不是所有动词都有被动语态

1 .happen, take place, break out, belong to, cost, last等不及物动词或词组无被动语态。

[误]The little girl has been taken good care . [正]The little girl has been taken good care of. 3. 动词短语不可分割，也不能省略其中的介词或副词。

[误] My brother has bought this bike for almost four years. [正]My brother has had this bike for almost four years. 4. 一些特殊动词, 如borrow, finish, begin, buy, start, return, marry, open, join等短暂动词构成的现在完成时的被动语态不能与表示一段时间的状语连用。其否定式则可以与for或since 构成的时间状语
