　　A Letter of Reply

　　Dear Li Ming，

　　I’m very glad to hear from you.Concerning my plan after graduation，I will probably continue my study as a postgraduate.

　　I have the following reasons.First of all，a higher degree and beaer educational background will give me an edge on the fierce competition of job-hunting because the fact that millions of college students enter the job market annually makes it difficult for US to find the job we want.Besides，as far as I am concemed，knowledge is，undoubtedly,an invaluable treasure of 　　human being，and we should make full use of our youth to learn as much knowledge as possible.of course.staying in the Ivory Tower doesn’t suggest that l will be cut off from society;instead.I will get involved in social and practical activities in my spare time.

　　Taking all aspects into account.I choose to further my study and get a master’s degree.

　　Many thanks for your concern.Best wishes!

　　Your sincerely,

　　Wang Lang

　　Internet Slang

　　Internet slang such as LOL (laughing out loud) and ROFL (rolling on the floor laughing) enjoys great popularity among teenagers nowadays. In fact, it becomes so popular that many terms now cross from computer-mediated communication to face-to-face communication. Some teenagers even use them in essay writing.

　　People have different opinions towards this phenomenon. Some people say that it will help enrich the language system and make language diverse. But others disagree, saying that these new words, being abbreviations for existing, long-used phrases, don’t “enrich” anything; they just shorten it and their total effect on language will be trivial.

　　In my opinion, Internet slang has little effect on language in general, but will greatly influence individuals’, especially teenagers’ language development. The reason is that overuse of Internet slang will lead to the lack of proper punctuations and grammar and has numerous misspellings in writing. That will drastically reduce chances of employment when students graduate and seek jobs. So, for the sake of their future, teenagers had better refrain from Internet slang.
