1. T: OK. Stop here. Please look at the compounds on the blackboard and guess their meanings in groups.

(学生讨论后，说出词意，猜不出来的教师给出答案。)

3. (讲解合成词，完成3。)

T: All of you did a good job. I think it’s good to help people in trouble. There is an old saying “A friend in need is a friend indeed”. I hope we have many friends who can get along well with us. English words also have their own friends. Let’s help them find good friends.

(用小黑板或幻灯片出示3。)

T:　 You can do it in groups.

(学生讨论两分钟后，请同学口头完成，并猜测词义。)

T: Who has helped them find friends? What’s the meaning when they are together?

S₅: “Grand”and “daughter”are good friends. I think its meaning is“孙女”，“外孙女”.

S₆: “Grand” and “child”are good friends. It means“(外)孙或孙女”，“孙辈”.

S₇: “Down” and “stairs” are good friends. Its meaning is“楼下”.

　　 “Fire” and “place” are good friends. It means“壁炉”.

(板书granddaughter, grandchild, fire, downstairs, 要求学生猜测其词义，并掌握。)

…

T:　 You’re very helpful. We should often help each other. In English, there are many words like these. It’s useful for us to make our vocabulary bigger. Let’s try to give more examples. Please do it in groups.

(学生讨论过后，让各组汇报本组讨论结果。对表现最佳、说出合成词最多的小组给予表扬。)

Step 5 　Project 第五步 　综合探究活动(时间:5分钟)

(学生口述合成词时，教师在黑板上写出几个合成词让他们猜测词意。)

2. (听2录音，完成2。)

T: You have fun in playing this game. But everyone can’t be happy all the time. What happened to Carly when the flood broke out in her hometown? Listen to the tape and finish 2.

(板书flood，要求学生理解，词组break out要求学生掌握。)

1. (再读1a，比较含有since和for的现在完成时的两个句子，通过做游戏简单了解此语法，完成1c。)

T: Read 1a again and complete the sentences with “since” or “for”.

(1)You have been in New York for a long time.

(2)The city has improved a lot since I came here a few years ago.

T:　　　 Can you find the differences between them?

Ss:　　 Not exactly.

T:　　　 Let’s play the game “In the waiting room” to learn about it, OK?

Ss:　　 Great.

(老师讲述游戏规则，并用幻灯片把范例呈现出来。)

T:　 Today Dr. Lee is very busy. He has lots of patients in the waiting room. Nurse Wang is helping him to make the order. Oh, how careless Nurse Wang is! She can’t find the list paper. But luckily, the patients had their arrival time written on the card. Can you help Nurse Wang to list the order? Now each group is given a box with cards with time inside. Please pick up one and decide at first whether you should use “since” or “for”, and then ask one another “How long have you been in the waiting room?” and try to help Nurse Wang to arrange the order.

(幻灯片出示范例。) For example:

Present time: 11 o’clock in the morning

Time: Patient 1(7:30); Patient 2(10:00); Patient 3(9:10)

S₁: How long have you been here?

Patient 1: I have been here since 7:30./I have been here for three and a half hours.

Patient 2: I have been here for one hour./I have been here since 10.

Patient 3: I have been here since 9:10./I have been here for one hour and fifty minutes.

So, the order is Patient 1, Patient 3, Patient 2.

(活动提示：可引导学生用for和since表示自己的时间，加强对这两个单词区别的认识，以便迅速排出顺序。)

2. (再读1a，编造相似对话。)

(给学生几分钟，然后读范文。)

T: Who wants to read your dialog to us?

A and B: Let’s have a try.

A:　　　 You’ve been in Paris for five years. What do you think of there?

B: Wonderful.

A: But I heard the weather and the traffic were terrible there.

B:　　　 They used to be. But the city has improved a lot since I came here five years ago.

A:　　　 Is it a good place to live?

B:　 Yes. The traffic isn’t terrible again and the streets aren’t dirty again, and there are many excellent places to visit. You must come for a visit.

A:　 I will go there if I have a chance.
