Inventions are created every day because people would like to make life easier. There are famous inventions like the TV and the bicycle. TV provides us with different kinds of information so that we can know more about the world. We watch entertainment programs to relax ourselves. Besides，some learning programs help us with our study. The bicycle is very useful，too. We go to school or work by bike. Its not so expensive that most of us can afford it. It makes no pollution，which is good for our environment. Whats more，bicycle riding is a kind of exciting sports which is quite good for our health.

When we meet problems in doing our homework or taking exams，it will tell us how to solve them! Thats all. Thank you very much!,
