What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It looks beautiful on a fine sunny day and it can be very rough when there is a strong wind. What other things do we know about it? Of course, the sea is very large. In the world there is more sea than land. The sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep everywhere, some parts of it are very great. At one spot, near Japan the sea is nearly 11 kilometers deep! Just think of it, the highest mountain in the world is only about 9 kilometers high! If you have swum in the sea, you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own lights. Some have great jaws. With their great jaws, they swallow fish larger than themselves. The sea can be very cold. Deep sea divers know this well. At the top of the water may be warm. Then as the divers go down, the sea becomes colder and colder.

You may know that vitamin C is important to your body，but do you know that vitamin D is important to your body as well? Vitamin D has a significant role in calcium homeostasis(钙稳态) and metabolism(新陈代谢). It is sometimes called the “sunshine vitamin” because it’s produced in your skin in response to sunlight.

Vitamin D can help bones and muscles grow strong and healthy. If a person is short of vitamin D，he or she may have problems like rickets(佝偻病) and osteoporosis．Rickets is mainly found in children. Osteoporosis，the thinning of bone，is a common problem as people get older. Studies in these years have found that vitamin D may also have other uses. If someone is short of vitamin D, he may have heart problems or die from some cancers.

The easiest way to get vitamin D is from sunlight. But many people worry about getting skin cancer and skin damage from the sun. Also, even skin color has an influence. Darker skinned people get less vitamin D than lighter skinned people. Older people get less vitamin D than younger people. You can also get it from foods. Some food such as cheese and egg yolks (蛋黄) have some vitamin D．But most of vitamin D in the American diet comes from food like milk with the vitamin added.

Now more doctors are testing for vitamin D in their patients. However, some doctors worry that if people take too much vitamin D, it might be bad for their body. At the same time, skin doctors tell people to be careful with strong sunlight.

It is nice to know what the weather will be like when we plan a trip. Do you know anything about the history of weather? Don’t look at the sky. Don’t look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back.

It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree.

Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand — no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why?

A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move.

In this example studying tree rings uncovered an exciting fact about the history of man.

1.We can find out the weather of five years ago by counting the rings of a tree trunk ____.

A. from the left to the right　　　　　　　　

B. from the right to the left

C. from the inside to the outside　　　　　　

D. from the outside to the inside

2.If the ring was far from the others, we can conclude that the weather of that year was ______.

A. bad　　　　　　 B. sunny　　　　　　　 C. favorable　　　　　　 D. rainy

3.By studying the rings of dead trees in an area of New Mexico, the scientist found _______.

A. why the people had to leave　　　　

B. where the people had to go

C. what the people had to eat　　　　　　

D. how the people left

4.The ancient people usually lived where there were plenty of trees mainly because ______.

A. trees provided an exact record of weather for research

B. trees could supply them with fruit and food to live on

C. trees could supply them with shades

D. trees were materials for fires and buildings

5.By giving the example of an area of New Mexico, the author tries to prove 　　　　 .

A. trees can’t live in the area without population

B. that studying trees is important for the history of man and weather.

C. what the real relation is between tree rings and the history of man and weather

D. the history of man is important for the history of trees

You may know the English letters A, B and C. But do you know there are people called ABC? You may like eating bananas. But did you know there is such a thing as a “banana person”? How strange! Are these people from “another earth”? No. They are just Chinese people like you and me.

ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a “banana person”. A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside—thinking like a Westerner and yellow outside—looking like a Chinese.

Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don’t speak Chinese. Also, they are not interested in Chinese politics.

But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas Chinese. These people may be citizens(公民) of another country like the US, Canada or Singapore. But they have Chinese blood. Their parents, grandparents or even great-grandparents were from China. They all have black eyes and black hair. But they are not Chinese citizens. They are not people of the People’s Republic of China. For example, we all know the famous scientist C. N. Yang (杨振宁). He got the Nobel Prize for Physics in 1957. And he is an American citizen.
