John likes Science best at school. He thinks it's very useful to human beings and the world. So he has a great dream. He wants to be an excellent scientist when he grows up.
To make his dream come true, he should study harder and harder, and read more books about science. After all, acquiring a lot of knowledge is very necessary. But at the same time, he should exercise more and keep healthy. He must have a healthy body, and then he can work better for his dream.
It is said that “ Where there is a will, there is a way !" I think he can make his dream come true in the near future.
