The population of the Earth is growing faster. It is important that we look after the Earth. We need it!
The Earth gives us a lot of things. We also give the Earth a lot, but some of the things are not good.
In nature, when something dies, other animals and plants get food from it. Every animal or plant gives food for other animals or plants. However, animals can’t get food from many of the things that we ‘give’ the Earth. Animals and plants can’t eat metal, plastic and glass. These things will stay in the ground for many, many years.
Some rubbish is very dangerous for plants and animals. In some places, many animals live together. One animal makes food for many more animals. If we put rubbish and chemicals in the water, the plankton(浮游生物) can die. If there isn’t any plankton, many animals have nothing to eat.
So what can we do? Don’t leave any rubbish in the countryside! Don’t make so much rubbish!
1. The Earth gives us ___________.
A. food B. rubbish C. chemicals D. pollution
2.When something dies in nature, _________.
A. water and grass are polluted B. plastic and wood become food
C. other animals and plants get food D. metal and glass stay in the ground
3.We must _______ to look after the Earth.
A. put metal in the ground B. use more wood
C. keep frogs in the water D. make less rubbish

The population of Earth is still going up. There will be less and less good land for growing crops in the future. People worry that there will not be enough food for everyone in the middle of this century.
Recently scientists have discovered one strange plant
named fedtschenkoi(玉吊钟)may help. It can absorb(吸收)carbon dioxide(CO₂)
at night. It only needs 10 times less water than food plants like beans. This means it
can grow in the desert(沙漠).
In which ways could this plant help us?
Since deserts are increasing in size because of the changes in Earth’s climate, growing plants there will be more and more important. Although it is dangerous to
eat this plant, scientists can still study something about it: how it absorbs CO₂ at
night while many other plants only do this during the day, and why it is suited to the
desert.
There is another direction to take the research in. Producing a desert plant to eat
will be difficult, but there is still possibility to use the genes(基因)from this plant and put them into food plants.
The other way is to grow this type of plant for fuel(燃料). At the moment we
grow plants for fuel in good land. If we do it in deserts instead, more good land can be used to grow plants for food.
Desert plants have special qualities, which could be an answer to our future food
or energy needs. Scientists are working hard on it.
The Desert Plant Could Help | |
The problems of the future | ◆The population on Earth is becoming 1. than before. ◆There is less and less 2. land for growing crops. ◆There will not be enough food in the future, which makes people 3. |
The discovery of the scientists | ◆It is an 4. plant named fedtschenkoi. ◆Food plants like beans need 10 times 5. water than it does in deserts. |
The ways it could 6. us | ◆The scientists are studying how it absorbs CO₂ and why it is 7. for living in desert. ◆It is 8. to use genes from one plant and then put it inside another. ◆It will be better if we can grow plants for fuel in deserts 9. than in good land. |
Conclusion | ◆Because desert plants have special qualities, it may 10. our food and energy problems in the future. |

It is said that as the population of a city grows, so do its problems. Pollution, too many cars, and crowded streets are just a few of the problems. One way to deal with these problems is city trains. Traveling to different parts of a city by train means fewer cars and buses on our roads, cleaner air and more open streets. In recent years, cities such as Guangzhou, Shenzhen and Shanghai have all built city train lines.
The first city train line in China was built in Beijing. The oldest part of the train line, from Beijing Zhan to Ping Guo Yuan was opened in 1969. Its length was 23.6 kilometers. With the development of the city after 1980, more trains are needed. A new train line was built to help move people around the city center. The 16-kilometer-long “circle line” was finished in 1987. Since that time even more train stations have been built and today the train lines in the city are over 50 kilometers long.
For the 2008 Olympic Games, the trains of Beijing was very important. Most of the people who went to watch the different sports games during the Olympic Games traveled by train.
1.This passage tells us about _____.
A.the problems in big cities B.city trains
C.the history of Beijing D.2008 Olympic Games
2.How long was the first train line in Beijing?
A.About 16 kms. B.About 23 kms.
C.About 33 kms. D.About 50 kms.
3.In 1977, which of the following places in Beijing could you go to by train?
A.Chao Yang Men. B.An Ding Men.
C.Che Gong Zhuang. D.He Ping Men.
4.When was the 16-kilometer-long “circle line” finished in Beijing?
A.In 1969. B.In 1980. C.In 1987. D.In 2008.

A very important world problem is the growth of population on the earth. The population of the world today is more than 6,500,000,000. That is a great number and we know it quite well. The important thing is not how large the population of the world is now, but is the rate (速度) of the growth. It is about 1.63% every year after the number of dead people has been taken away.
To give you some ideas of the birth rate, look at the second hand of your watch. Every second, four babies are born in the world. Another baby! Another baby! Another baby! Another baby! You can not speak quickly enough to keep up with the birth rate. The population is growing faster and faster. So it goes on, hour after hour. In one day, people have to find food for over 350,000 mouths more.
This great growth of population will make a big problem by the year 2010—there will be as many as 7,000,000,000 people on the earth! So this is one of the biggest problems that you are going to meet within your life.
