Good morning, everyone! Today I’m going to talk about inventions.
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, to We go to school or work by bike. It’s not so expensive that most of us can afford it. It makes no pollution, which is good for our environment. What’s more, bicycle riding is a kind of exciting sports which is quite good for our health.
Though there have been many great inventions, I wish to invent a kind of pen which can help us write more quickly and neatly. When we meet problems in doing our homework or taking exams, it will tell us how to solve them.
That’s all. Thank you very much.
