三、时态讲解：现在完成时

（1）构成：现在完成时由助动词have + 过去分词构成，助动词have 有人称和数的变化。第三人称单数用has，其余用have.

现在完成时的否定式直接在助动词后面加上not、疑问式是把助动词提到主语之

1）现在完成时通常表示在说话之前已经完成的动作或存在的状态。说话人强调的是该动作或状态对现在的结果或影响。

My daughter has just gone out. 我女儿刚出去。

I’m sure we’ve met before. 我肯定我们以前见过面。

She has arrived. 她到了。

2）表示持续到现在的动作或状态，往往和包括现在在内的表示一段时间的状语连用，如recently, already, just, lately, for…, since…,yet等。如：

I haven’t heard from her these days. 这些日子我没有收到她的信。

We haven’t seen you recently. 最近我们没有见到你。

They have been away for two years. 他们离开已经两年了。

She has been with us since Monday.

★注意：

a)since和for的区别

since后接时间点，如1993，last term, yesterday, the time I got there

for后接一段时间，表示“长达多久”，如ten years, a while, two days等。Exercise: 用since和for填空

1. Jim has been in Ireland ______ Monday.

2. Jill has been in Ireland ______ three days.

3. His aunt has lived in Australia ______15 days.

4. Mary is in her office. She has been there ______ 7 o'clock.

5. India has been an independent country ______1974.

6. The bus is late. They've been waiting ______ 20 minutes.

7. Nobody lives in those houses. They have been empty ______ many years.

8. Mike has been ill ______a long time. He has been in hospital ______ October. 2)短暂意义的动词如arrive, leave, borrow, buy, begin, start, die等，在完成时当中不能和表示一段时间的状语连用，因为它们表示的动作不可能持续。因此，不能说：He has come here for 2 weeks. ×

The old man has died for 4 months. ×

以上三句话可以改为：

He has been here for 2 weeks.

The old man has ______ _______ for 4 months.

They have _____ _____ only for 5 minutes

2）have (has) been 和have (has) gone的区别：表示“曾到过某地”要用“have (has) been”; 表示“已经去某地”要用“have (has) gone”。试比较：

Where has he been? 他刚才到哪里去了？（已经回来了）
