A rabbit is running into its 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 run too. They know that 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 found some food, it goes back to his home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.
Some animals say things by making sounds. A dog barks, for example, 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 what 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 living 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 example,  contains four or five hundred thousand words. But we do not 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 meet a new word, look it up in the dictionary. A dictionary is the Most useful book.

.British people are famous for drinking tea. But brother and sister, Sarah and Bobby Green, became young millionaires when they opened a chain of American-style coffee shops in the UK.
Having the idea: It started when Sarah took a weekend trip to New York to visit her brother Bobby. One evening, in a Thai restaurant, Sarah told Bobby how much she wished she could buy American-style coffee in London. Bobby suggested they started their own coffee shop. Sarah fell in love with the idea.
Doing the Research: Back in London, she spent a whole day on the London subway, getting off the train at different stations to taste the coffee. “It was terrible, and I knew there was a gap (空缺) in the market.” In 1995, they opened their first Coffee Republic shop in central London.
Making it work: The first year was very difficult. British people were not used to the names of American coffees, like latte and macchiato. But being successful was their dream and they were not going to give up. Today, there are over 100 Coffee Republic shops all over the country and the company has £30 million a year.
Advice for others: Sarah has now written a best-selling book about their experience, called Anyone Can Do It ! She hopes it will help other young people to start their own businesses. She says, “If you think you have the energy, then get out and follow your dream.”

Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.

One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.

By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.

Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.

GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.

1.GM foods ________.

A.are a quick way to produce food

B.grow in the wild

C.are safe

D.are grown only in rich countries

2.Why do some people not like GM foods?

A.They are not useful.

B.They are not helpful.

C.They are not natural.

D.They are not cheap.

3.From the reading we know that ________.

A.GM foods will disappear one day in the future

B.GM foods will not disappear in the future

C.people will not be interested in GM foods

D.people will have to stop using GM foods
