周至二中：孙静

教学目标

1，明确常见的被动语态形式

2，能够区分完成时态的各种形式和概念

3，了解完成时态的被动语态在应用时的注意问题

教学步骤：

1，七种常见被动语态形式

1）一般现在时的被动语态

(am/is/are + 过去分词）

如: The work is done during two days. 2) 一般过去时的被动语态

(was/were + 过去分词）

如: He was sent to the hospital immediately after the accident. 3) 一般将来时的被动语态

(will/shall + be +

过去分词

或

+ be going to + be + 过去分词）

如: The work will be finished soon. 4) 现在进行时的被动语态

(is/am/are + being+ 过去分词）

如: The bridge is now being constructed. 5) 现在完成时的被动语态

(have/has +been + 过去分词）

如: The radio has been repaired when we phoned the shop. 6) 带情态动词的被动语态

(情态动词

+ be + 过去分词)

如: This can be done in a few minutes. 7) 动词不定式的被动式(to be + 过去分词)

如: It is an honor for me to be asked to speak here.

完成时态的各种形式区别

现在完成时主动态

have / has + 动词过去分词

现在完成时被动态：

have / has + been + 动词过去分词

现在完成进行时：

have / has + been + 动词现在分词

3，

完成时态的各种形式概念

1) 现在完成时(have/has + 过去分词)

现在完成时的动作或情况虽然发生在过去，但它强调的是与现在的关系，用来说明现在的情况。现在完成时不能与表示确定的过去时间的状语连用, 如: yesterday, two weeks ago, in 1978, when I got there 等, 现在完成时常与

already, always, often, ever, never, yet, not...yet, just等不表示明确的时间副词连用, 还可以和表示时间一直延续到目前的带since, for 的状语及包括现在在内的词连用。如: now, today, this month, this year, recently, these few days 等。不能用在现在完成进行时态的动词，如：be, have, like, love, know, believe, hate等。

一般过去时则是表示过去某时发生的动作或情况, 与现在毫无关系。

现在完成时的被动语态表示动作发生在过去, 到现在已经完成或对现在仍有影响, 其构成是: have/has been + done。例如：

1. The dirty clothes have been washed.

脏衣服都已经洗了。

2)

现在完成进行时

(have/has + been + 现

在分词）

4，注意问题: 1）. 副词的位置

often, usually, always, never, hardly, seldom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）. 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。如：

[误] Great changes have been taken place in China since 1978.

[正] Great changes have taken place in China since 1978. 3）. 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. 4）. 一些特殊动词, 如borrow, finish, begin, buy, start, return, marry, open, join等

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：

My brother has had(不能用has bought) this bike for almost four years.

How long has this book been bought?

How long ago was this book bought? 5，（课堂练习）
