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.
B. they are beautiful and lovely
C. they keep the balance of nature
D. they give us a lot of pleasure
B. Many kinds of animals have died out.
C. About 170 kinds of animals have disappeared forever.
D. All kinds of animals are in danger.
B. Once a certain kind of animals is gone forever, there will never be any more.
C. Killing all rats and mice may cause some problems.
D. People must not kill any animals.
B. Animals in danger will not be killed any more.
C. The number of some animals in danger will increase.
D. Animals in danger will be kept away from people.

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.

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.
B. progress made in Beijing"s air quality
C. Beijing"s air pollution
D. the difference between Hainan and Beijing

provide effective medical care to their patients without the help of numerous other
medical employees. From the viewpoint of the patients, the nursing staff is particularly
important. Nurses are usually in close contact with patients as long as they are in the
hospital.
A nurse does not study for as many years as a doctor. however , each must be equally
dedicated. Caring for sick persons requires a great deal of patience and concern. Most
nurses work long days, and they often must work at odd hours or during the night.
Under the supervision (监管) of the head nurse, the nursing staff must provide nursing
services on a 24-hour basis and attend to patients" needs. This responsibility continues
around the clock, and so nurses must work in shifts. A shift is a period of duty, usually
eight in length. The nurses on the ward rotate their shifts. Some take turns working night
duty; others work odd shifts.
A nurse must always be alert. She can never afford to be careless. This is true in all
nursing situation, but it is especially true in the intensive care unit. Patients under
intensive care are critically ill, and they must be monitored at all times. The nurses who
do intensive care duty have one of the most demanding jobs in the hospital.
Serving as a nurse can be a very rewarding job. But it is not an easy one. Not every
person is suited to become a nurse. Only very dedicated people have chosen nursing as a
profession.
