Summary

Talking bar 说说吧

Do you think it necessary for students to own cellphones ?Give your opinion and your reasons.

Key words: Agree: fashion convenient functionsDisagree: waste money/time break rules

interrupt be harmful to

• Some students think a cellphone necessary and convenient to them. They consider it a fashion to have a cell phone, which can help them contact with their friends wherever they are.

• However, there are some bad things. Playing with the cellphone may affect our grade and decrease our interest in study. We can often send messages, surf on the net, listen to music and even take photos rather than study English. Moreover, many students are able to use cell phones to cheat during exams, which is not a good thing. Finally, a cellphone may cost a lot of money and the radiation is harmful to us.

• In a word, we shouldn’t own a cellphone.
