Computer

There is no doubt that the invention of computer is revolutionary.

While at the mean time, it also brings some problems to people, at least to me.

1. It wastes time, which is valuable. The computers are invented and designed to make life easier. While it seems that our life is not that good with computers. It calculates scientific questions much faster than human beings, but as a matter of fact, I don't have that much equations to solve everyday. Generally, it will take me less that 5 minutes to solve a math problem by computer, but it might take me an hour after that to deal with some messages on Facebook, Gmail, Youtube... ...

2. It changes the way I learn. It is hard for me to think before a computer while I am reading. All kinds of links, ads, pictures are misguiding you to irrelevant pages. It is hard to follow my heart and dip deeply into one point. I read much more webpages, electronic articles than reading books. But I learn much less form internet than that from books. It seems that the information online is huge, but the valuable knowledge is really few. People rely on Google so much that they are losing the ability of memorizing, which is the most important ability of learning.

3. It changes the way I live. If I live in a world without computer, I will definitely spend more time on reading books, writing words, articles on paper, chatting with friends and family more by phone. I will care more about my health, stay out of the office more and enjoy the sunshine.

The computer is a double edge sword, it is not easy to handle.
