Nowadays, some students have a new use of the Internet—searching for answers online. There are different opinions about it.  Some students consider it a way of saving time and helping with homework. Others believe it will develop bad habits and make students lazier. As far as I’m concerned, we’d better solve problems by ourselves. When students copy answers without trying to solve the problems by themselves, they miss the opportunity to develop their problem-solving skills. (话题12　科学与技术) Moreover, this habit can make them dependent on the Internet, reducing their ability to think independently and creatively.  All in all, searching for answers online can be useful, but it should be done properly. We students should try our best to finish our homework by ourselves. If necessary, we can turn to the Internet for help.  返回目录> (话题12　科学与技术) $$
