幾年級的?需要多少字?Should we totally turn to the InternetAs the development of internet, it is now a common phenomenon that find answers on line for the problems which one does not know how to deal with. Usurally, searching answers on line offers a convenient way to solve problems. But for students, it sometimes may not a good news. Some one could easilly find key for homeworks, instead of doing it by themselves. They justfinish the homeworks, and learn nothing about the knowledge.Frankly speaking, I used to get help on line. When I have any question, I search it on line, and generally I could get an answer. I never just copy the answer. I study it, and try to understand it. Therefore, internet is a good tool for me.
