广州版.小学英语.现在完成时(讲义 答案)

Present Perfect Tense

（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前。以

study 为例，其否定式、疑问式和简单回答形式如下：

（2）用法：

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。

EX: 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.

b）have (has) been to /have (has) gone to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）

Where has he gone? 他上哪儿去了？（人不在）

They have been to Canada. 他们到过加拿大。（现在已经不在加拿大）

They have gone to Canada. 他们到加拿大去了。（可能在路上和已经到加拿大）.

除了上述两个短语，我们还常见到“has been in+ 地点+ for + 一段时间”的句式，意为“待在某地多长时间了”，例如：

This lady has been in Germany for seven years.

EX: 根据中文上下文，选用has been to, has gone to 或has been in 填空。

①Mrs. Webb _______________________ Guangzhou for more than two weeks.

②—Where is Doris?

—She ___________________________the Carrefour(家乐福).

③—How many times __________ you __________Okinawa(冲绳)？

—Three times.

c）现在完成时不能和表示过去的时间状语连用，如yesterday, last year, in 1976, two days ago, just now, when I came in，但可以和already, yet, sometimes, always, often, before, lately, recently, once, twice, ever, never等连用。例如：
