Finally, when it comes to the health of your skin today and into the future you should avoid smoking all together. In addition, you should drink alcohol only in moderation. Both smoking and excessive alcohol consumption can negatively impact the health of your skin in significant ways.
Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets (彗星) which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Newton, who was a brilliant (有才华的) mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse (椭圆) .
Now Halley set to work. He figured out the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearances had been 75 to 76 years apart (相隔).
This seemed very strange to Halley. The different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets, as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.
It was an astonishing idea! Halley felt certain enough to make a prediction of what would happen in the future. He decided that this comet would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested.
In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet has been called Halley’s comet, in his honor.

A friend of mine named Paul received an expensive car from his brother as a Christmas present．On Christmas Eve when Paul came out of his office，a street urchin (顽童) was walking around the shining car．“Is this your car，Paul？” he asked．Paul answered，“Yes，my brother gave it to me for Christmas.” The boy was surprised．“You mean your brother gave it to you and it did cost you nothing？Boy，I wish…” He hesitated．
Of course Paul knew what he was going to wish for．He was going to wish he had a brother like that. But what the boy said surprised Paul greatly. “I wish,” the boy went on，“that I could be a brother like that.” Paul looked at the boy in surprise, then he said again, “Would you like to take a ride in my car？”
“Oh yes，I'd love that．”

He ran up to the steps. Then in a short while Paul heard him coming back, but he was not coming fast. He was carrying his little disabled brother. He sat him down on the step and pointed to the car.
“There she is, Buddy, just like I told you upstairs. His brother gave it to him for Christmas and it didn't cost him a cent. And some day I'm going to give you one just like it…then you can see for yourself all the nice things in the Christmas windows that I've been trying to tell you about.”
