精美语篇
Recently our class discussed the advantages and disadvantages of surfing the Internet. Here are our conclusions.
Of course, surfing the Internet clearly has some advantages. There is no doubt that the Internet makes communication easier and helps us keep up with the latest information. It also provides us with various ways to kill time, such as online shopping, online movies and online chats with friends.
Like anything else, the Internet is not perfect. Being addicted to it can waste a lot of time, especially for us students; not only can our studies be harmed by our spending too much time online, but we often hear news of students who met dangerous people online or even got cheated.
In my opinion, when surfing the Internet, we should be aware of both the advantages and disadvantages. Only in this way can we really benefit from it.
