For thousands of years, people have used plants to make medicines. They used different parts of the plants —the roots, the leaves, the flowers, and the bark (树皮). Today, doctors have rediscovered more medicinal (药用) values of some plants. Let’s look at some examples.
Foxglove is a common plant. People have used it to make the heart slow down. Recently scientists have developed another drug from it. This new drug helps prevent other heart problems.
In some areas, malaria has been a problem. Scientists have learned that the bark of a South American tree, the cinchona, can be made into a drug to prevent malaria. For a long time, the Chinese have known that a special plant, wormwood, can also fight malaria. Scientists have been working with it to develop new drugs against malaria.
In Germany, some scientists studied garlic (大蒜) for four years. They found that it helps prevent the build-up of plaque (血小板) because too much plaque is bad for health. This very common plant continues to be studied.
As we know, there are about 250,000 kinds of flowering plants in the world. Scientists have only studied little more than one percent of plants for their medicinal value. Maybe medicines for AIDS and cancer will be made from the other 99 percent

A rabbit is running into his hole. You may ask, “What happened?”
Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they ran, too. They know there is danger. The rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of language. When a bee finds some food, it goes back to his home. It can’t tell the other bees where the food is by speaking to them, but it does dance in the air. This tells the bees where the food is.
But animals say things by making sounds. A dog barks, for examples, when a stranger comes near. A cat purrs(发出呼噜呼噜的声音) when pleased. Some birds make several different sounds, each with its own meaning.
But human beings have something that no animals have---- a large number of words about things, actions, feelings or ideas. We are able to give each other information to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animals can do this. No animals has the wonderful power of language.
No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.
People in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for examples, contains four or five hundred thousand words. But we don’t know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we met a new word, look it up in the dictionary. A dictionary is the most useful book.

Gerrard Street is at the center and is the most important street in the area. There is a large Chinese community(社区) with a lot of Chinese restaurants, Chinese supermarkets and shops in this street.
In the 1950s, it was a poor area and everything was very cheap. At the same time, the world rice market changed and thousand of farm workers in Hong Kong lost their jobs. They began arriving in London to look for work. They found jobs in the restaurants in this area. Many British people like Chinese food, and the restaurants were popular.
These restaurant workers often worked 17 hours a day and had no time to learn English. As more Chinese arrived, more shops and businesses grew up. Wives came and joined their husbands and children came and joined their fathers. The community grew, and Chinatown was born.
In the 1970s and 1980s, British-born Chinese started to have a better education and this brought economic(经济的) success to the area.

       Who hasn’t enjoyed eating peanuts? Did you know that although peanuts look like nuts and taste like nuts, they aren’t nuts at all? They belong to the pea family, so they are called peanuts. The peanut grows flowers above ground, but its “fruit” grows underground. It grows in more countries than most other “nuts”.
The peanut is a native South American plant. Scientists believe that it grew wild in Brazil long ago. They think that for several thousand years the early peoples of South America made it a part of their diet. These peoples were nomads who moved on when a natural food could no longer be found in one area. Along the way they probably let fall some peanuts, which got into the ground and grew. This is believed to be the way the plant reached the place where the Incas(印加人)lived. The Incas, from about 1100 to 1532, thought highly of peanuts. The peanuts were eaten in several forms and used as sacrificial offerings(祭品)to the Incan Sun God. Later in the 16th century, European soldiers had brought peanuts to other parts of the world, including North America, Africa, Asia, Europe, and Pacific Islands.
Although peanuts were found native in South America, they are now grown in almost every country that has warm weather. India produces the most peanuts. China’s production is next, followed by the United States.
The peanut is special in more ways than one. It can be eaten raw, boiled, roasted, or fried. Hundreds of widely different products have been made from it. Carver, an American scientist, set himself the task of discovering new uses for eating and for many other products.
Peanuts are very highly nutritious and are also high in protein (蛋白质). Americans use about seven-tenths of their protein in the form of meat. In India, where the poor can’t pay for meat or milk, peanut meal and peanut milk have been produced. These have been a great help to the poor.
New products are continually being made from peanuts, among them peanut cheese and a powder that becomes peanut butter when water is added. The fact is that peanuts are so healthy that they were used by astronauts. The unusual nut that isn’t a nut is one of nature’s most amazing gifts.
【小题1】 Although we like eating peanuts, many of us don’t know peanuts belong to _______ family.
A.the peaB.the nutC.both the pea and the nutD.neither the pea nor the nut
【小题2】 Which paragraph(段落)mainly talks about the history of the peanut?
A.Paragraph FourB.Paragraph Three
C.Paragraph TwoD.Paragraph One
【小题3】What does the underlined word nutritious mean?
A.Helpful for staying healthy.B.Helpful to the poor.
C.Delicious and tasty.D.Rich in fat and oil.
【小题4】 Which of the following is TRUE according to the article?
A.Nomads always stayed in the same place.
B.The peanut was first found in South America.
C.Astronauts ate lots of peanuts to keep healthy.
D.China grows fewer peanuts than the US.
【小题5】What is the purpose of the article?
A.To show that peanuts belong to the pea family.
B.To advise us to use more peanut products.
C.To tell us some new uses of peanuts.
D.To let us know more about peanuts.

Are people less happy or happier when they get older? If your answer is “happier”, then you are right, based on a study published five years ago. It found that people generally become happier and experience less worry after age fifty. In fact, it found that by the age of eighty-five, people are happier with their life than they were at eighteen.

The findings came from a Gallup survey of more than three hundred and forty thousand adults in the United States in 2008. At that time, the people were between the ages of eighteen and eighty-five.

Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were the highest among adults between the ages of twenty-two and twenty-five. Stress levels dropped sharply after people reached their fifties.

Levels of happiness were the highest among the kids and those in their early seventies.

The survey also found that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men did.

So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

Title: Relationship Between Age and   1.
