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.

Pollution means adding dirty or harmful things to land, air, water and so on. As a result, they are no longer pleasant or safe to use. Pollution is bad for animals and plants, and it even makes people’s health in danger. In our daily life, we can see different kinds of pollution in many places. There are three main forms of pollution: land pollution, air pollution and water pollution.
Land pollution is caused by solid waste, such as cans, bottles and some plastic things which aren’t broken down quickly. It makes the environment look very bad. However, air pollution is more serious than land pollution. It is much worse in cities and towns because of the fumes(废气) from traffic and the waste from human activities. When people drive their cars, fumes which are most made up of CO2, NO2 and SO2 are given off. After the gases get into the air, they may mix with clouds. Then they will become some harmful chemicals (化合物) falling on the ground with rain. It is one of the reasons for soil erosion (土壤侵蚀) which is one example of water pollution.
Various kinds of pollution will cause many health problems. People have realized they must change this serious situation. There are many ways to control pollution. To develop alternative energy is very popular in many countries. China, for example, has made up its mind to be a leader in this field. It is trying hard to make full use of energy from the sun and wind. It has paid plenty of money to make electric cars and trains instead of traditional traffic. We should also take action to make our environment cleaner every day. Take cloth bags while going shopping and drive cars less. We have only one earth. We must take steps now to help protect our environment for the future wherever we are.

New rules and behaviour standards (行为规范) for middle school students came out in March. Middle school is going to use a new way to decide who the top students are. The best students won"t only have high marks. They will also be kids who don"t dye (染) their hair, smoke or drink. Here are some of the new rules.
Tell the truth. Have you ever copied someone else"s work on an exam? Don"t do it again! That"s not honest. If you have played computer games for two hours in your room, don"t tell your parents that you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-Loving Month in our country. Is your school doing anything to celebrate? You should join! That way, you can learn more about animals and how to protect them. Have you ever quarreled（吵架）with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others, not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Perhaps you"ll discover（发现） Earth II someday. Don"t look down at anyone. Everyone"s ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don"t let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet aren"t for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework.

A taboo(忌讳，禁忌) is a social action that is not allowed. Every culture in the world has its own taboos. The breaking of a taboo sometimes makes people feel uncomfortable. I learned this through my own experience.
Last weekend, Wang Lin and I showed two foreigners around our city. Mr Singh was from India and Mr. White from USA. When I held out my left hand to shake hands with him, Mr. Singh seemed to be unhappy. Mr. White, however, was quite casual. He said hello to me with a big smile and a wave of his hand.
In the evening, we stopped at a restaurant for dinner. I noticed that Mr. Singh didn’t touch the beef and Mr. White seemed not to like chickens’ claws. During the meal, Wang Lin said sorry to Mr. Singh and continued to explain that we didn’t know it was a taboo in India to shake one’s left hand. Mr. Singh explained that since oxen are sacred(神圣的) in India, people don’t eat beef there. Mr. White joined in and said that it was not usual in the states for people to eat chickens’ claws. He went on to say that Americans don’ t usually get into each other’ s personal space. Marriage, job and age are their taboos. Isn’ t it a good lesson to remember?

Main idea	The taboos in every country are ____小题1:_____. People sometimes feel ____小题2:____ if one breaks a taboo.
