Advantages and disadvantages of the Internet
In the modern world, the Internet has come into our life. Lots of students use the Internet as a tool for their studies. They look up the meanings of new words and learn history or geography on the Internet. They also use the Internet to read news or send e-mails.
But every coin has two sides. Some students spend too much time playing online games and chatting with friends. They are not interested in their studies. At the same time, they become weaker and weaker in body.
In a word, the Internet brings us not only a lot of convenience but also troubles. As students, we should make good use of the Internet.
