六、短文改错
Dear Editor,
Last week,our class had a discussion about if high school students should use the Internet to learn the English.We held different view about it.
Some people agree with the idea,say that they can download the latest English information from the Internet.What’s more,they can not only share our experience of learning English with others,but also watched English films and listen to English songs.
However,others which are against the idea say that it is a waste of time and energy.Besides,it is easy for the students to addicted to online games or chat with others rather than learning English.
In my opinion,we can benefit a lot from the Internet if we can use it proper in learning English.
Yours,
Li Hua
