To buy or not to buy,

that is the question!

Speaking

Jane wants to buy a cellphone. Before she buy one, she asks her Parents and her best friend what they think.

TO BUY OR NOT TO BUY ?

agree

disagree disagree

Agreement

Absolutely. That's exactly what I was thinking. That's a good a point. That's just how I see it. That's worth thinking about.

Disagreement

I disagree. I'm afraid I don't agree. Well, it depends. Well, I don't know. Well, I'm not so sure about that.

1. You are Jane. You want to buy a ellphone. You think that a cellphone is very useful because:

1. I can use a cellphone to call 2. my parents if I am late. 3. 2. I can use a cellphone to call 4. for help. 5. 3. I can use a cellphone to stay 6. in touch with my friends.

2. You are Jane's best friend. You don't think Jane should buy a cellphone because:

1. We don't usually need cellphones.

2. We are not allowed to use cellphones in school.

3. It is better to use the money for something more important.

3. You are Jane's mother. You do not think Jane should buy a cellphone because:

1. Cellphones are too expensive. 2. Jane should not spend too 3. much time on the phone. 4. 3. Jane is too young to have 5. a cellphone.

4. You are Jane's father. You think that Jane should buy a cellphone because:

1. If Jane has a cellphone, I can 2. always find out where she is. 3. 2. A cellphone will help Jane 4. feel safe. 3. Jane can use a cellphone to 4. send messages to her friends.

Conclusion

Every coin() has two sides. Cellphones are everywhere and have positive and negative effects on our life. So we should take a critical() view of the cellphone culture.

In my opinion, you'd better not buy a cellpnone.

First, it's not safe. Cellphones are valuable things. Taking cellphones with you may cause trouble. You may be robbed of your cellphones. And what's worse, you may be hurt by the robbers. Besides, you may have the short messages with lots of sex ()in it. They do great harm to you.

Second, they may have bad effects on your study, which is your main task. You may waste your time in sending messages and talking with your friends

about nothing with your study.

Third, it's too expensive for you and not necessary. You can use the telephone cards, which are much cheaper.

On the other hand, even if you have a cellphone, use it in the right way. Never overuse it . Care much about your mobile manners. A person with good mobile manners is the one who thinks of others before he dials and always keeps it in mind that the people he's with should always be more important than a phone call.

homework

1. Review the expressions about

agreement and disagreement 2. Talk about this topic: should students
