I’m very glad to receive your letter. From your letter, I know you have shown  小题1:  great interest in inventing new things. That’s great. As for how to be an inventor, there is no quick answer to   小题2: .
Coming from different cultures and having different backgrounds, inventors do not seem to have much  小题3: common.  But creative thinking,   小题4: is greatly valued, is perhaps the basic skill an inventor should have. In order to explore new possibilities, you will have to learn to break 小题5:    from old thought patterns. When you get stuck, try to look at the problem in        小题6:    many ways as possible. Each new way may improve your understanding.
More importantly, always keep it in your mind   小题7: success is no accident. It is the result of a long process of trial and error. Above  小题8:  , the main task for you is to study hard and try to learn more knowledge. This, of course, will lay a solid foundation.
Hope your future invention will make a difference.
Good  luck
