With the development of science and technology, computers have played an increasingly important role in our daily life. Computers make our life more convenient. F or example, we can not only look for useful information but also chat with friends on a computer. However, every coin has two sides. Many students spend more than three hours surfing the internet without a rest. As a result, they become weak and shortsighted. In addition, some students rely so much on computers that they find answers online instead of thinking for themselves now.
All in all, only if we use computers in a proper way, can we make the best use of them.
