Step Two: Studying the Grammar Discovering useful structures Tell students what they should do first. Ask them to read the EXAMPLE in Exercise 1 on Page 21. Make sure that they know what they should do. Finish Exercise 2, and check the answers. T: Do you have any questions? Ss: Sometimes it's difficult to decide whether we should use the past tenses.

T: This is a good question. The difference between the two tenses is usually confuses many students. We can learn enough about this from the

explanations on the screen. That's the way to solve this problem. Ok, let's finish Exercise 2 on Page 13 first. Let students do it. They can have a discussion to check the answers. After that, check with the whole class, in fact teacher should enlarge this structure for students. If possible teacher could show all the grammar knowledge to students.

1. 现在完成时和一般过去时的区别

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, 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

2)

现在完成进行时

(have/has + been + 现在分词）

3)

现在完成时的被动语态

(have/has +been + 过去分词）

E.g. The radio has been repaired when we phoned the shop. 注意事项：1. 主语是行为动作的承受者。如：

The Temple of Zhang Fei has been rebuilt.

张飞庙已经过重建。

2. 说话时已经完成的动作或出现的结果。

如: The door has been locked. 门已经被锁上了。

3. 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）

4. 用在时间和条件状语从句中, 表示将来某时已完成的动作。如：

We’ll start as soon as the work has been finished. 工作一完成我们就立即动身。

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

[正] Great changes have taken place in China since 1978. 6. 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. 7. 副词的位置

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

been中间。

[误] Such a man has been hardly believed.

[正] Such a man has hardly been believed.
