Teaching Difficulties: To understand and use the present perfect tense.※教学准备※Teaching Aids: 1. A computer for multimedia use. 2. A picture.※教学过程设计※Step 1 Greetings and Revision

1. Greet the class as usual and check the homework.

2. Ask students to read the sentences of Grammar focus aloud.

Step 2 Learn the Present Perfect Tense

1. 用法：

1) 表示过去发生或已经完成的动作对现在造成的影响或结果。

2) 某些动词的现在完成时可表示过去某一时间开始并一直持续到现在（包括现在）的动作或者状态，可以和表示延续的时间状语连用。表示持续动作或状态的是延续性动词。

2. 构成：have / has + p.p.

have not = haven’t has not = hasn’t

3. have been to & have gone to区别

have / has been (to) 表示“曾经到过某地”，说话时此人不在那里，已经回来。侧重指经历。

have / has gone (to) 表示某人“已经去某地了”，说话时此人可能在路上或已到那里，反正不在这里。

4. 一般过去时与现在完成时的区别

比较：I have seen the film. 我看过这部电影。（我了解这部电影的内容）

I saw the film last month. 我上个月看了这部电影。（只说明上星期看了这部电影，不涉及现在情况）

一般过去时的时间状语有：yesterday, last week, …ago, in1980, in October, just now…

共同的时间状语有：this morning, tonight, this summer, before, already, ...

现在完成时的时间状语有：for, since, ever, never, just, already, yet, in past years, …
