As the development of Internet, people like to use computer to do many things, we can say that computer has been part of our life. People get used to reading the news and then sharing their opinion on the Internet, then more and more slangs come into being. I think these slangs are good for expression but should not be used officially.
We can see the people make some sentence short, like by the way is short for btw. At first, we may not like it, but when we find that everybody is expressing like this, we will follow and then get used to it. Internet slangs are another way for people to express themselves, it is quit short and convenient.
我们可以看到人们使一些句子变短，比如“by the way”缩短为“btw”。刚开始，我们也学不喜欢，但是当我们发现大家都在这样表达时，也会跟着使用，然后开始适应。网络用语是人们表达自己的另一种方式，简洁而方便。
Though Internet slangs are favored by many people, we must know it clearly that these words should not be used in official writing. Because these words will change its meaning as the time goes on, sometimes people will misunderstand the meaning.
Internet Slangs are very popular now, it provides a way for people to communicate and we can use them in the certain situation.
