Step 2 Learning new grammar 1. 被动语态构成：

be+ vt.过去分词

注意:be动词随人称和时态的变化而变化

主动语态变被动语态口诀：



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。

2. 这是什么时态和语态？



I have been used in offices and homes since the 1970s. 

I never forget anything I have been told! 

I have even been put into space rockets and sent to explore the Moon and Mars. 现在完成时被动语态: have/has + been + 过去分词

肯定句：

Your computer has been repaired. 否定句：

Your computer has not been repaired. 一般疑问句：Has your computer been repaired? 特殊疑问句：What has your computer been done?

3. 现在完成时的被动语态两种意味：

1）动作发生在过去, 到现在已经完成或对现在仍有影响, 句中常有：already , yet等状语

例如：

The door has already been locked.

门已经被锁上了。

2）

动作或状态始于过去, 持续到现在, 并可能持续下去。如：

He has been told about it for many times.

有人告诉他这事很多次了。（可能还会有人告诉他）

句中常有：

In the past…years, for+ 一段时间, since+具体时间, so far, many time等状语

3）特殊情况：

用在时间和条件状语从句中, 用现在完成时表示将来某时已完成的动作。如：



工作一完成我们就立即动身。

We’ll start as soon as the work has been finished.



如果采取措施，我们立刻就会解决这个问题。

If measures have been taken, we will solve the problem right away. 注意：

1. 副词的位置

often, usually, always, never, hardly, seldom, already等副词置于have/has和been中间。如:

[误] Such a man has been hardly believed.

[正] Such a man has hardly been believed. 2. 短语动词不可分割或省略其中的介词或副词。如：

The SARS patients have been taken good care of. 3. 一些特殊动词, 如borrow, finish, begin, buy, start, return, marry, open, join等短暂性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。若要表达相应的意思，则需改换动词或时态。如：

×His grandfather has died for three years.

√His grandfather has been dead for three years.
