M2U3 Computers 一、话题美文

With the development of science and technology, communication has become increasingly convenient. People can communicate with their friends or relatives freely in different ways. Among them chatting on the WeChat is the most popular. ①Almost every senior high student has their own WeChat number, with which they can chat with their friends, ask their teachers to help them solve their puzzles and exchange their thoughts.However, some students have spent too much time chatting with their WeChat friends. ②What’s worse, some students have hundreds of WeChat friends, eating up almost all their spare time, even their study time.I do think that WeChat can bring us much convenience and benefit, but what we should do is use it properly and reasonably. We should limit our time on it and devote ourselves to our study.
