课型：新授课课时2执笔/审核/授课人：林娟授课时间。

一、学习目标。

1. 学习现在完成时。现在完成时的结构为“助动词h**e/ has + 动词的过去分词”。

2. 学习并掌握重点词汇和句型的用法：take place, h**e/ has been to, so…that…, improve, by the way等。

3. 体会语言的规律，提高归纳总结能力。

二、重难点预设。

i.根据句子意思，请用h**e或has填空。

1. wefinished our homework.

2. li huacome back from japan.

5. theywon the game.

4. —are your parents at home ?

5. —i h**en’t seen your brother these days. —oh, hequanzhou.

三、知识链接语法。

rita, you h**e just come back from your hometown. 此句用的是现在完成时态。现在完成时，表示在说话之前已发生或完成的动作，并对现在造成影响；或是过去发生的动作持续到现在。

其结构为“助动词h**e/ has + 动词的过去分词”（动词的过去分词形式分为规则变化和不规则变化，规则变化同动词的过去式，不规则变化详见课本后的不规则动词表）。主语为第三人称单数时用has. peter has just come back from ningde.

主语为其他人称时用h**e。 we h**e finished our homework. 应注意现在完成时表示过去的动作对现在造成了影响或结果时，其标志词有already（已经），yet(仍然，尚)，just, ever, never, before等；表示过去的动作持续到现在时，其标志词有“for+段时间”，since…, so far, by now, these days等。

现在完成时的否定形式是助动词h**e/ has后加上否定词not. h**e not的缩写形式为h**en’t, has not 的缩写形式为hasn’t. i h**e not / h**en’t seen my teachers for many years.

现在完成时的一般疑问句是把动词h**e / has调到句首，剩下部分变成一般疑问句，意为 “还有……吗？”“过吗？”肯定回答为yes, …h**e/ has.

否定回答为；no,… h**en’t / hasn’t. 也可用no, never. 或 no, not yet.

—h**e you seen the film before ? yes, i h**e. /no, i h**en’t.

练1】 tom has seen the film. (改为否定句)

练2】i h**e received eight letters since last week. (改为一般疑问句并作出否定回答)

练3】—what do you think of the movie war horse

wonderful. it’s the best one that iin the past few years.

练4】weour english teacher since he moved to beijing.

六、成果展示。

1、巩固上面七个短语和句型。

1）拥有一个好暑假2) 发生。

3) 越来越漂亮4）去过。

5）如此……以至于6）改进英语。

7）去了。2、模仿例句，根据3的**，用has / h**e been to / h**e gone to 进行口头练习。

七、快乐达标。

一）词与词组。

1. take place“发生，举行”，指计划或安排好的。take place 为不及物动词短语，所以不能用于被动语态（注意和happen的区别，happen是指偶然发生，happen也没有被动语态形式）。

练习1】 great changesin our hometown in the past five years.

a. take placeb. took placec. h**e taken place

2. h**e/ has been to “曾经到过某地”，现在不在那里了。h**e / has gone to “ 已经去了某地”，现在没有返回。

h**e / has been in “在某地待了多长时间”，常与段时间状语连用。

练习2】 —why are you worried？

3. so… that…“如此……以至于……”用于引导结果状语从句。 he got up so early that he could catch the early bus.

注意： so.. that… 句型可以和too… to…句型相互转换。
