语法核心突破

The Present Perfect Passive Voice

1. 构成：现在完成时被动语态由”has/have + been + 及物动词的过去分词”构成。Has/have为助

动词；

They haven’t been told the exciting news yet, have they? 他们还没有被告诉这个令人激动地消息，对吗？

1）since then, since+从句，so far, by now, up till, now, recently, lately, already, yet等常用于现在完成时的句子中。

2）ever, never, already, yet等副词用于现在完成时的被动语态时，放在has或have之后

2. 现在完成时被动语态用法

1）表示一个被动的动作发生在说话之前，强调对现在造成的影响和结果

The door has been locked. 门已经被锁上了。

2）表示一个被动的动作或状态发生在过去，持续到现在，并有可能持续下去，常于for或since 引导的时间状语连用，或用于“How long---?”句型中

How long has the machine been used? 这台机器使用多久啦?

3. 现在完成时被动语态应注意的几个地方

1）注意与一般过去时被动语态的区别。一般过去时被动语态所表示的动作和状态与现在没有联系，而现在完成时被动语态强调与现在的联系

The bridge was built last year. 这座桥是去年建的。

The bridge has been built. 这座桥已经建好啦。

3）注意特殊动词：borrow,finish,begin,buy,start,return,marry,open,join等构成的被动语态不能和表示一段时间的状语连用，否则要改换动词和状态，

How long has this book been bought?(F) How long ago was this book bought?(T)

但这类动词的否定句可以和一段时间状语连用。

No book s have been bought since last week. 从上周以来，没有人来买过书

【典型例题】

1. -Why does the Lake smell terrible?

-Because large quantities of water .

A. have polluted

B. is being polluted

C. has been polluted

D. have been polluted 【解析】D考查动词时态，语态和主谓语一致。根据前一分句可知所填动词表示过去发生的动作对现在产生的影响，时态用现在完成时，动词与主语是被动关系，用被动语态。主语是large quantities of water，其中心词是quantities，是复数，谓语动词用复数

2. His sister left home in 1998, andsince.

A. had not been heard of

B. has not been heard of

C. had not heard of

D. has not heard of

【解析】B 考查现在完成时的被动语态否定句。按照句意为：他的妹妹在1998年离开家，自从那时就没有音讯了。用现在完成时的否定结构

【语法专练】

1. We’ve been told the good news, but when and wh ere to go for the exciting on – salary vocation yet.

A. are not discussed

B. have not been discussed

C. is not being discussed

D. has not been discussed
