T: This class we’ll learn a new tense---The Present Perfect
Tense. It is one of the most important tenses during our junior
middle school. So we must learn it by heart. First, read the
teaching aims. Now, look 、listen and think about the form and
the time of the tense.
1. I have closed the door. 3. He has had breakfast.
2. We have begun our class. 4. We have known each other before.
Let’s watch the tense of the sentences.
一．现在完成时的构成
Form: havehas + PP 注：havehas 是助动词
二、现在完成时的时间状语：already(已经)、just（刚刚）、ever
（曾经）before（以前）yet（还，未）
三、变否定句：在助动词后加not，把already 变成yet，且放
在句末
1. I haven’t closed the door yet.
2. He hasn’t had breakfast yet.
3. We haven’t begun our class yet.
4. We haven’t known each other before.

四、变一般疑问句：把助动词havehas 提前，末尾用yet
1. Have you closed the door yet？
2. Has he had breakfast yet？
3. Have we begun our class yet？
4. Have we known each other before？
五、现在完成时的主要用法1，let’s listen and think.
例如：1、I have closed the door. The door is closed now.
2、I’m not hungry now. I have already had breakfast.
1、动作发生在过去；
2、且对现在有一定的影响或产生的一定的结果。
六、过去分词分为规则变化和不规则变化
T: PP 有规则变化和不规则变化两种。动词的过去分词规则变化
形式与过去式一样，1、 通常在动词后加ed，如：opened，looked；
2、辅音字母加y 结尾的，把y 变成i 加ed如：study-studied；
3、重读闭音节，且最后三个字母是辅元辅的，双写最后的辅 音
字母如：stopped，chatted。
不规则变化的课本后有表，要求同学们尽快背过。但不规则有规
则的规律。
（一）ABC 型: eat ate eaten see saw seen
（二） ABB型: build built built win won won
（三）AAB型: beat beat beaten
（四）ABA型: become became become

（五）AAA型: put put put
T: OK. We have learned about the Present Perfect Tense.
