水泥早强剂一般在:英文作文上网的利与弊

随着时代的发展，上网已经变成了非常普遍的事。不论是大人还是小孩，只要提起电脑，都会想到上网。可是，上网是有利也有弊。
我知道很多人去上网，主要是为了玩游戏，这样很耽误学习。所以，有些人认为，中小学生缺乏自制力。
但是，有很多人赞成上网，为什么？因为上网能给人们提供很多帮助。首先，网络就像一个图书馆，能很容易的查到很多资料，比查阅书籍速度快；其次，在网上可以读到更丰富的新闻；此外，上网还有其它作用，例如，E-mail,网上通电话等等。
其实，上网有它的益处与弊处。我们利用它开扩视野，学习知识，但一定要掌握好分寸。
Along with the time development, accessing the net already turned the extremely universal matter. No matter is adult or the child, so long as mentioning the computer, all think of internet. But, accessing the internet is advantageous ,but also has shortcoming.
I knew very many people access the net, mainly is for playing games, which is very bad for the study. Therefore, some people believed, the elementary and middle school students lack the self-control.
But,there are many people approving to accessing internet, why? Because internet can provide to the people very helps. First, the network looks like a library, we can look up very many materials easily,and it is quicker than the speed of consulting books; Next, we may read a richer news on-line; In addition, accessing the net also has other functions, for example, E-mail, telephoning on the net and so on.
Actually, accessing the net has its profit and the shortcoming place. We use it to open to expand the field of vision, the study knowledge, but must certainly grasp the discretion.

Nowadays,people can get almost any information from the internet,but some information can have negative influences on young people and even our society. The following essay discusses whether there should be censorship of information in society or not.
To begin with, some information is harmful for children, therefore we should protect children from some information. By this I mean, children are easily influenced and they cannot distinguish what is right or real and what is wrong or unreal, as they are immature, and hey probably imitate what they have seen. As a consequence, we should protect children from some information such as excessive violence or obscene material, so that they can grow up to be valuable members of society.
Another point to bear in mind is that some information which could be harmful to society should be censored. For example, some material that encourages racism,violence or terrorism threatens social security, and it might lead to some serious social problems, such as crimes. Therefore, the government should ban this kind of information in films,books or on the internet.
However, people do have the right to choose what they what to know, and they should be allowed access to most information. Further more, most adults are good people and will not be influenced in a negative way easily, thus they should have the freedom to decide what they want to know, and the government should not censor all information, as the government is only a group of people after all.
In conclusion, parents should strictly control what their children watch or read, and the government should censor such information in children’s books, films or websites. In addition, the government should ban some information which encourages racism, violence and terrorism, as it is harmful to society. However, on the other hand, since it is people’s right to choose what they want to know, the government should not censor most information.
