Have you ever tried to hide your feelings from someone during a conversation?
1.
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.

E.For example, when two people are arguing over something, we say they are red 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.
