2．论据要充分。欲证明自己的观点必须有充分的证据。作者可以列举事实、展示数据、提供事例、借助常识或利用亲身经历。【典例展示】
上网对孩子好还是不好，好在哪里，不好在哪里，请谈谈自己对这个问题的看法。词数100左右。【联想词汇】

__________，students will benefit a lot from Internet.
3．但同样也会有许多负面影响。
____________it can also spread many side effects.
答案：1.We should say that every coin has two sides　2.Generally speaking　3.But【范文借鉴】
We should say that every coin has two sides，so it is with surfing online.
Generally speaking, students will benefit a lot from Internet.People can get lots of useful information,listen to the music and chat with friends far away.The most important is that we can meet many foreigners speaking English as their native language，which can help us improve our English rapidly.We can send E-mail to our good friends in a few seconds.And we don’t need to wait for so long time as receiving a letter as before.But it can also spread many side effects.For example，there are some unhealthy news and pictures on web which will not do good to teenagers.And some students may become addicted to the games，wasting a lot of valuable time.
On the whole, it will give you both good and bad things.The thing that matters much is how you make use of it.
