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.

There are about 80.000.000 mines under the ground in more than 60 countries. It is difficult and dangerous to clear these mines.About 50 people including many children were killed or hurt each day.In 2003，APOPO，a Duch research company that trains the animals,came up with the idea of using rats to search for the mines.

The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell.The rats were about 75 cm long and weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.

In January 2004，the  APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later，the rats were no longer afraid of people and the things around them.Then they were trained to connect a click sound with food.After the rats had learned that ,the trainers then taught them to tell the different between the smell of mines and other smells.When the rats could do it，the click was sounded and they were given a bit of bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“You have to be patient.Sometimes I get angry,but then again.I tell myself these are animals.”

After nine months’ training,the rats were taken to 4 minefield. They ran across the minefield ,stopped, sat and searched the ground to tell the deminers that they smelt out a mine. Then the mine was cleared.It had taken two deminers a day to clear a 200 m² minefield. But with the help of two rats they could finish it in two hours.

The rats and the deminers saved thousands of lives.“The rats did this job much better than we expected.So far they have helpde to make almost 2.000.000 m² of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.

There are four girls. They go to school by car every day. Their parents drive them all to school.
One day, after the girls arrive at school, Angie says, “Let’s go to class an hour late. I don’t want to take the math test today.” The other three girls think it is a good idea, because they all don’t want to take the test. Angie says, “But our teacher will be angry if we come late. So we need a good excuse(借口).” “Oh, that’s easy,” says Susan. “ We just tell the teacher that my mother’s car has a flat tire(轮胎坏了). So we are late.” All the girls think it is a good excuse. When the girls arrive at the classroom an hour later, the math test is over. The teacher is very angry. “Why are you late?” asks the teacher. Susan says, “My mother’s car has a flat tire and we have to wait for her to repair it.” Then the teacher says, “Sit down, girls. Take out a piece of paper and a pen. Write down which tire is fault(出故障) on the paper.” The four girls look at each other and they don’t know what to write.[来源:学科网ZXXK]
