We all do it. We all need it. Most of us need to do it for seven to nine hours a night. It is of course sleep. Many scientists believe the truth. An adult should get eight hours sleep every night. However, some people can live without feeling sleepy after as little as six hours of sleep. But other people need about ten hours a night. Babies usually sleep between 14 to 17 hours a day. Usually they only stay awake for one to three hours.
Do you take a nap (打盹) in the day? Some adults and children need to nap. This just depends on the person. One thing scientists have learned is that man is the only mammal (哺乳动 物 ) that stops himself from going to sleep. This can be bad for our bodies in many ways. Scientists believe not sleeping enough can make us eat more. And not sleeping enough can make us put on weight. Hopefully you are a good sleeper and get a good night’s rest tonight!

Scientists from the Ohio State University have found that people are able to tell other people’s feelings according to changes in the colour of their faces. Scientists studied pictures of people’s facial expressions.2.For example, happiness makes our faces a little red. Disgust (厌恶) creates not only a blue-yellow colour, but also a red-green colour on our faces.
“We believe these colour changes are the result of small changes in blood.” 3.Does the colour alone help people tell others’ feelings?
To figure this out, scientists added colour changes to pictures of faces. 4.They were able to tell the feelings 75% of the time without any difficulty.
This is why there are some Chinese sayings that connect feelings to the colour of one’s face.5.When a person is very angry, we’d say he or she is blue in the face.

In the 13th century, Marco Polo, the world known Italian traveler, saw many wonderful things in China. One of the things he discovered was money made of paper. People in the West did not have such kind of money until the 15th century. However the Chinese began to use it in the 7th century.
Paper was invented by a Chinese man called Cai Lun almost 2,000 years ago. But it was not made in Europe until the year 1100. Four hundred years later, a German discovered that he could make the best paper from trees. After that countries rich in forests, such as Canada, Sweden, America, Finland became the most important ones in paper making.
Paper can be used in many ways. The common uses include newspapers, magazines and books. But do you know that paper can be used for keeping warm? In Finland, the farmers wear paper boots to keep their feet warm in the snow. And even houses can be insulated from heat or cold with paper.
However, we have to understand that paper still comes from trees now. If we keep on wasting so much paper, there will not be any trees left on the earth some day in the near future. Every day people throw away about 2,800 tons of paper in our city. It takes 17 trees to make one ton of paper. This means that we are cutting down nearly 48,000 trees every day. The fact is that it takes more than 10 years for a tree to grow.
So we must start saving paper right now. We can use both sides of every piece of paper. We can make useful things out of used paper. We can use china cups instead of paper ones. When shopping, we can use fewer paper bags and reuse them if we have some.
In short, we should keep a balance (平衡) between using paper and protecting trees, and do it now before it is too late.

A lovely young lady opened the door and she brought him a large glass of milk. He had it slowly, and then asked, “How much do I owe (欠) you?”
“You owe me nothing,” she replied. “Mother has taught me never to refuse to show your kindness.” He said, “Then I thank you from the bottom of my heart.”
Years later, the woman became seriously ill. The local doctors sent her to the big city, where specialists (专家) can study her illness. Dr. Howard Kelly, now famous, was called in for the consultation ( 会 诊 ). When he heard the name of the town she came from, a strange light filled his eyes. Immediately, he rose and went to her room. He recognized her at once and decided to do his best to save her life. From that day on, he gave special attention to her and her illness.
After a long time, the lady was well again at last. Dr. Kelly asked the hospital office to pass the final bill to him. He looked at it and then wrote something on the side.

Finally she looked, and the note on the side caught her attention. “Paid in full with a glass of milk.”
