    One cold morning in winter, I went alone to a hillside to do some hunting.  I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me.  There was no cover near him. Surely I could shoot him.

    To my surprise, he came toward me! He was curious, I supposed, or maybe he was stupid.  For this was not a youngster, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers(鹿角) was clearly in sight.

    I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me.

    What happened next was hard to believe. But it all seemed quite natural. I held out my hands and scratched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head.

    I scratched and touched his head and body. His nose touched my shoulder. I fed him with my last sandwich.

    Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn't, either. Not after that. I just watched him go, a strong deer carrying a proud head.

    I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around.

    You will now understand why I gave up hunting from that day on.

    Last Friday, Just before the 66^th National Day holiday, I conducted interview with James Watson, a famous American scientist, talk about how to become a successful scientist. On his opinion, to be a scientist, we needed to be very fond of science. What's most, we have to keep practicing as well as learn from other successful scientist. If we want to be a successful one, besides hard-working, we are supposing to set up for a clear goal as well. James Watson also suggest that every child who is curiously about science should make your effort to realize the dream of becoming a scientist.
