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 keep healthy. He must have a healthy body, and then he can
work better for his dream.
It is said that "There is a will, there is a way!" I think he can make his dream come
true in the near future.
