Good morning, everyone ! Today, Im going to talk about inventions. Inventions are created every day because people would like to make life easier. There are famous inventions like 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. It makes no pollution, which is good for our environment. Whats more, bicycle riding is quite good for our health. Its cheap, too. Though there have been many great inventions. I wish to invent a kind of pen to help us write more quickly and neatly. When we have problems in doing homework, it will tell us how to solve them. Thats all. Thank you very much.（答案不唯一） 马上分享给同学
