Teaching Procedures

Step 1 Greetings and Revision

     Greet the class as usual and check the homework.

     Ask students to read the sentences of Grammar focus aloud.

Step 2 Learn the Present Perfect Tense

  1. 用法

  构成：

have(助动词) + p.p

has(第三人称单数助动词) + p.p

have not 常缩略为haven’t

has not 常缩略为hasn’t

现在完成时的用法

ever 意为“曾经”，用于疑问句或否定句中，放在助动词与过去分词之间。

e.g. Have you ever been to Hong Kong?

你曾去过香港吗？  
I haven’t ever spoken to her.

我未曾和她说过话。  

never意为“从来没有”常与before连用，多放在助动词与过去分词之间。  

e.g. I have never travelled by plane before. 我以前从来没有乘飞机旅行过。  

2. have been to & have gone to区别

比较：He has been to Beijing.

   他曾去过北京。

 （人已回来，可能在这儿）

 He has gone to Beijing.

他已经去北京了。

（人已走，不在这儿了）。

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。
