Step 4 Practice 第四步 练 习 （时间：15分钟）
1. （通过对1a的学习，使学生学习运用在1a中曾经出现的词语，继续贯彻学了就用的原则。教师可以找
本地的两个地方做比较，并和三个学生做出示范，以确保学生没有畏难情绪。）
T: Now let’s make a dialog, using the words in 1a, and compare a new place and an old one. Which place is better to live in? I’d like to do it first. Who’d like to be my partner? I’m Kangkang. Who’d like to act as Jane, Maria, and Michael?
For example:
Jane and Maria: Mr.Zhao, shall we go to the zoo for a picnic?
Mr.Zha Go to the zoo for a picnic?
I’ve been there before. It’s a very narrow place for so many animals to live in. And so many buildings are around it and so many people visit it. It is very crowded. Especially, several chemical factories are doing a lot of harm to animals. It’s very dangerous to animals. The animals are not comfortable, I think.
Jane and Maria: We mean the new wild zoo. It is said that it is very big.
Michael and Mr.Zha Why not?
(On weekend, they get to the new one.)
Mr.Zha Oh, my God! It’s a very beautiful place and it is very big. Look! Some animals are playing on the hills.
(尽量使用2中动物的名称。)And ducks are speaking to us in the clean water. Look!…

Shall we have a picnic here?
Jane and Maria and Mr.Zha Why not?
Mr.Zha I’ll send e-mails to my friends.
Michael: Come on.
2. （学生四人一组练习，也可以模仿以上对话，也可以自编对话。）
T： Now it’s group work time. You can imitate or you can make your own dialog like this.
3. （学生表演。）
T: It’s the time for you to show it. Volunteers?
4. (听录音，完成2。此部分的动物名称对话中已用过。为此部分的学习打下了基础。)
Listen to the tape and write down the letters of the pictures. Does the pollution do a lot of harm to animals? Do you think it is a good idea to move the zoo to a new place?
5. (通过学生体会3提供的两个句子，让学生对短暂性动词和延续性动词有一定的认识。)
I came to Ren’ai International school one year ago.

（1）keep has kept for / since
（2）finish has finished
（3）be have been
（4）have has had
（5）be away from has been away from

Step 5 Project 第五步 综合探究活动（时间:10分钟）

Place
Time
School
Home
Town
Others
In the past
At present
Reasons
In the future
(通过这项练习进一步巩固复习1a,1b的内容，学生在模拟生活的场景中进行“真实”的调查、采访，使学到的知识能真实地运用到现实生活中，即学了就用。同时，让学生写Report, 提高学生的写作水平。)
2. Group competition.
(一小组成员说出一个过去式的句子（含有过去式的时间状语），另外几组争先恐后地把它改为现在完成时，既可以用since引导时间，也可以改为用for引导时间，可参考3的句子，同时也练习了Unit 1学习的直接引语变间接引语。)
T： Now let’s have a competition. One student in a group speaks out a sentence using simple past tense, and the other groups quickly change it into present perfect tense. Remember, you have to change the verb, and use “since” or “for” instead of “ago” or others.
For example:
Group 1: I bought an English dictionary last year.
Group 2: You / She / He have / has had an English dictionary since last year / for one year.
Group 1: I borrowed a novel from the library a week ago.
a novelhad kept since a week ago. for a week. Group 3: You / He / She have / has
