Millions of years ago there were many types of dinosaurs on earth. Most dinosaurs were plant-eaters.
The Apatosaurus, for example, had a long thin neck so that it could eat leaves from trees. Other dinosaurs
were meat-eaters. The Tyrannosaurus Rex killed smaller dinosaurs for food.
Dinosaurs were real animals that once lived on the earth, but they died out about 65 million years ago.
The disappearance of the dinosaurs is in some way a great mystery (谜). Some scientists think that the
climate (气候) changed suddenly. Fossils (化石) of trees tell us that the temperature dropped a lot and that
the level of the sea dropped as well. This means that it got suddenly much colder. Perhaps the dinosaurs
were too slow to change with the climate.
A new idea is that a meteor (流星) crashed into the earth. Scientists discovered a place in Mexico where
they think the meteor crashed. They think that there was a lot of dust from the meteor. The dust landed on
the plants.Also the dust blocked (阻挡) the sun"s light for as long as five years. Many animals, including
dinosaurs, were plant-eaters, and perhaps the dust killed them. This means there was nothing left for meat-
eating dinosaurs to eat, and so they died out. But, as many animals from that time didn"t die, we are not 100%
sure what really happened. |

Animals are natural resources that people have wasted all through our history.
Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in
the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on
the danger list today. About 170 kinds in the United States alone are considered in danger.
Why should people care? Because we need animals. And because once they are gone, there will never
be any more.
Animals are more than just beautiful and interesting. They are more than just a source of food. Every
animal has its place in the balance of nature (生态平衡). Destroying one kind of animal can create many
problems.
For example, when farmers killed large numbers of hawks (老鹰), the farmers stores of corn and grain
were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down
their numbers, the rats and mice multiplied (繁殖) quickly.
Luckily, some people are working to help save the animals. Some groups raise money to let people know
about the problem. And they try to get the governments to pass laws protecting animals in danger.
Quite a few countries have passed laws. These laws forbid (禁止) the killing of any animals or plants
on the danger list. Slowly, the number of some animals in danger is growing. |

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many
people on the island had a disease called beri-beri. He was going there to try and find
a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some
chickens. He didn"t eat them, but made experiments on them. The local people were quite
surprised at that. One day he noticed that his chickens became sick when they were fed
the food most Javanese ate-refined white rice (精炼米). When he fed them with unrefined
rice, also known as brown rice, they recovered. Eijkman realized that he had made an
important discovery - that some things in food could prevent disease. These things were
named vitamins (维生素). The Javanese were not getting enough vitamins because they had
actually removed the part that contains vitamins. Later, other diseases were also found
to be caused by the lack of vitamins in a person"s food.
Today many people know the importance of vitamins and they make sure they have enough
vitamins from the food they eat. If they don"t, they can also take vitamin pills. |

D. help the Javanese with their illness |
| 3. Why did Christian Eijkman raise some chickens? |

While students in Hainan are quite used to clear skies, Beijing teenagers are not so
lucky. As another warm winter approaches, the city can expect the normal clouds of smoke
caused by air pollution.
But things could start to get better soon. The government is co-operating with a US-
based environmental protection agency to update existing buses and trucks with clean fuel
technology. The new technology could reduce air pollutants in existing diesel vehicles (柴
油机) by 40 per cent. The programme will begin by testing buses in Beijing to see if the
technology can be applied to them.
"We encourage the development of public transportation. But at the same time we need
to reduce pollution from them," said an official.
Efforts are being made to improve the capital"s environment with tighter controls on
emissions (排放). Some heavily polluting factories and construction sites, such as those
owned by the steel giant Shougang Group, have been asked to cut production in November
and December or be closed. Beijing was the third polluted city in the world at the end of
last century, according to the UN. But thanks to recent measures, the capital has made
some progress. Last year 224 clear days were rated as having good air quality. In 1998
the air quality index (指数) gave just 100 days as good.
"I am glad to see an improvement," said a Senior 1 boy living in the northwest of
Beijing. "Compared to other places, the air quality of Beijing is still worrying though.
I hate the pollution. Once I was riding my bike in the morning when I almost had a traffic
accident because I couldn"t see a car only metres away from me in frog."
In early October, the skies were covered by such a thick fog that a display show by
the visiting French air force was called off.
Rapid development, industry, traffic fumes (烟) and sandstorms from the desert all
contribute to the city"s bad air. |
| 1. The passage is mainly about ______? |
| [ ] |
A. a programme to improve Beijing"s air quality
B. progress made in Beijing"s air quality
C. Beijing"s air pollution
D. the difference between Hainan and Beijing |
2. Which of the following is not the measure taken or to be taken to improve Beijing"s
air? |
| [ ] |
A. Clean fuel technology will be used in public transportation.
B. Some factories have been asked to cut production.
C. Some construction sites have been told to be closed.
D. A display show of airplanes has been called off. |
3. We can infer from the passage that, with the aim of being an ecological (生态的) city
by the 2008 Olympics, ______. |
| [ ] |
A. far more still needs to be done
B. nothing else needs to be done
C. all traffic has to be closed
D. the development of the city has to be slowed down |
| 4. Which is not correct according to the passage? |
| [ ] |
A. Beijing"s air quality is getting worse and worse.
B. Development, industry, traffic fumes and sandstorms are all the causes of bad air
quality.
C. Clouds of smoke in the sky is the common feature in the winter of Beijing.
D. The government is making every effort to stop air pollution. |
