national park is to protect the plants and animals that live there. But things that happen outside the park
also affect the life within it.
Everglades National Park is part of a much larger area known as the Everglades. At one time, water
flowed freely in the Everglades. During the rainy season, water would fill the Kissimmee River. Then it
flowed into Lake Okeechobee. Once the lake became full, water spilled over onto the flatland. From there
a shallow sheet of water moved slowly down the Florida Peninsula. Then it emptied into Florida Bay. This
shallow sheet of water was the Everglades River. It was only a few inches deep. But it was up t0 50 miles
wide and over 100 miles long.
The Everglades is home to many plants and animals found nowhere else in the world. Today, some of
these plants and animals are in danger of disappearing forever.
The main reason is that the Everglades is no longer a free-flowing river. Canals have been built to drain
(排干) most of the shallow river. People have also built a dam to hold back water from Lake Okeechobee.
Most of the water from the Everglades is trapped in man-made lakes. Cutting off the flow of water into
Everglades National Park has done more harm than good. Now it threatens the wildlife in the park.
Water pollution is another reason some plants and animals are disappearing. Years ago, large areas of the
Everglades were drained and turned into farmland. Today the fertilizers (肥料) used on crops are polluting
the water. The "river of grass" is slowly disappearing. Many kinds of plants are disappearing. Animals that
depend on these plants for food no longer have anything to eat.
The problems facing Everglades National Park are very serious. But there is still hope. Work is already
under way to save the Everglades. The federal government, the state of Florida, and several other groups
are all working together to try to undo the damage.
B. To protect the plants and animals.
C. To provide a fun place for people.
D. To keep animals from going in the park.
B. how big Everglades River was
C. what the Everglades used to be like
D. what happened to Everglades River during the rainy season
B. people cut the plants that the animals feed on
C. large areas of Everglades were turned into buildings
D. the water flowing into the Everglades has been cut off
B. some measures are being taken to protect the environment of Everglades
C. the environment of Everglades will be worse and worse
D. the government is worried about Everglades but has no way

deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these
people live in Africa, and are under age 5.
Malaria can be prevented and treated. However, many African nations don"t have the funds (基金) to
fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign
in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with
insecticide (***虫剂) is the simplest way to stop mosquitoes from biting at night. The chemicals last four to
five years. For $10, anyone can send a net to Africa and help save a life.
So far, NBN has raised $19 million and delivered 700 000 nets to seven countries. Families are taught how
to use the nets. Kids also get vaccines (疫苗) and vitamins. "Women line up for miles to get the medicine for
their kids," says NBN director Elizabeth McKee Gore. "They understand the importance." So do kids in this
country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star
Ruth Riley.
NBN"s biggest fund-raiser is Katherine Commale, a seven-year-old girl. She"s been spreading the information
about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach
that bed nets can save lives," she said.
Katherine has raised $ 42 000 for NBN. "She just wants those who need a net to have one," says her morn,
Lynda. "It"s pretty simple to her." To find out how you can help, visit nothingbutnets, net.
B. Because those nations don"t know what to do with it.
C. Because those nations don"t have the money for it.
D. Because nothing but nets can change it.
B. fund-raisers
C. families who are taught to use the nets
D. Katherine and her brother
B. By spreading information about bed nets.
C. By teaching people how to use bed nets.
D. By making video programs.
save the endangered species (物种). That"s a move similar to what a Texas A & M University researchers have
been undertaking for the past five years in a project called "Noah"s Ark".
Noah"s Ark is aimed at collecting eggs, embryos (胚胎), semen and DNA of endangered animals and storing
them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A &
M"s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the
species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100
years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into
the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
"The nuclear transfer (核子移植) of one species to another is not easy, and the lack of available panda eggs
could be a major problem," Kraemer believes. "They will probably have to do several hundred transfers to result
in one pregnancy (having a baby). It takes a long time and it"s difficult, but this could be groundbreaking science
if it works. They are certainly not putting any live pandas at risk, so it is worth the effort," adds Kraemer, who
is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.
"They are trying to do something that"s never been done, and this is very similar to our work in Noah"s Ark.
We"re both trying to save animals that face extinction. I certainly appreciate their effort and there"s a lot we can
learn from what they are attempting to do. It"s a research that is very much needed."
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another
B. host animals
C. qualified researchers
D. enough money
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China -the Native Place of Pandas Forever
B. scientists try to implant a panda"s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century
entertainment purposes-is fair and respectful? Zoo officials say they are concerned about animals. However,
most zoos remain "collection" of interesting "things" rather than protective habitats (栖息地).
Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural homes.
Zoos claim to educate people and save endangered species, but visitors leave zoos without having leamed
anything meaningful about the animals" natural behavior, intelligence, or beauty. Zoos keep animals in small
spaces or cages, and most signs only mention the species" name, diet, and natural range.
The animals" normal behavior is seldom noticed because zoos don"t usually take care of the animals" natural
needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and
physical exercise. This results in unusual and self-destructive behavior called zoochosis. A world-wide study
of zoos found that zoochosis is common among animals kept in small spaces or cages. Another study showed
that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears
spend 30 percent of their time walking back and forth, a sign of unhappiness and pain.
Furthermore, most animals in zoos are not endangered. Captive breeding (圈养繁殖) of endangered big
cats, Asian elephants, and other species has not resulted in their being sent back to the wild. Zoos talk a lot
about their captive breeding programs because they do not want people to worry about a species (物种) dying
out. In fact, baby animals also attract a lot of paying customers. Haven"t we seen enough competitions to name
baby animals?
Actually, we will save endangered species only if we save their habitats and put an end to the reasons people
kill them. Instead of supporting zoos, we should support groups that work to protect animals" natural habitats.
B. Unhappy.
C. Natural.
D. Simple.
B. behave strangely
C. often attack other animals
D. enjoy walking around
B. Zoos fail in their attempt to save animals.
C. Zoos should treat animals as human beings.
D. Zoos use animals as a means of entertainment.
B. giving examples of animals in the wild
C. questioning the way animals live
D. discussing the advantages of natural habitats
B. most animals in zoos are endangered species
C. some endangered animals are reproduced in zoos
D. it"s acceptable to keep animals away from their habitats
阅读下面的短文,并根据短文后的要求答题(请注意问题后的词数的要求).
Animals have been killed for their fur and feathers, for food, for sport, simply because they are in the way.(天生就该如此) Thousands of kinds of animals have disappeared from the earth forever. Hundreds more are
on the danger list today. About 170 kinds in the United State alone are considered to be in danger.
Why should people care? Because we need animals. And because once they are gone, __________________
_____________________________________________. Animals are more than beautiful or interesting or a
source of food. Every animal has its place in the balance of nature. 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 to protect animals in danger.
Quite a few counties have passed laws. These laws forbid the killing of any animal or plant on the danger
list. Slowly, the number of some animals in danger is growing.
________________________________________________________________________
2.Which sentence in the passage can be replaced by the following one?
The number of rats and mice increased very fast because there were not enough hawks to kill them.

a perfect time to look around and see just how dirty Britain has become. The sidewalks are stained with
chewing gum that has been spat out and the gutters (排水沟) are full of thrown away fast food cartons. Years
ago I remember traveling abroad and being saddened by the plastic bags, waste bottles at the edge of every
road. Nowadays, Britain seems to look at least as bad. What has gone wrong?
The problem is that the rubbish created by our increasingly mobile lives lasts a lot longer than before. If it is
not cleared up and properly thrown away, it stays in the bushes for years; a semi-permanent reminder of what
a dirty little country we have now. Firstly, it is estimated that 10 billion plastic bags have been given to shoppers. These will take anything from 100 to 1,000 years to rot. However, it is not as if there is no solution to this. A
few years ago, the Irish government introduced a tax on non-recyclable carrier bags and in three months
reduced their use by 90%. When he was a minister, Michael Meacher attempted to introduce a similar
arrangement in Britain. The plastics industry was against that, of course. However, they need not have
bothered; the idea was killed before it could draw breath, leaving supermarkets free to give away plastic bags.
What is clearly necessary right now is some sort of combined action, both individual and collective, before
it is too late. The alternative is to continue going downhill until we have a country that looks like a vast rubbish
tip (废物场 ). We may well be at the tipping point. Yet we know that people respond to their environment. If
things around them are clean and tidy, people behave cleanly and tidily. If they are surrounded by dirt, they
behave dirtily. Now, much of Britain looks pretty dirty. What will it look like in five years?
B. you can see Britain at its dirtiest.
C. you can see how dirty Britain is now.
D. the grass has thickened on the roadside.
B. rubbish lasts longer than it used to
C. our society is increasingly mobile
D. people in Britain are dirty
B. He failed in his attempt to introduce a tax on plastic bags.
C. His attempt to follow the Irish example with a tax on plastic bags was welcomed.
D. He had problems with the plastics industry who weren"t bothered about the tax.
B. There is more than one solution to the problem.
C. Britain will become an extremely dirty country in five years.
D. People tend to behave according to what they see around them
