It was not the first time for Shi Benliang, a senior physics major at Peking University, to feed cats. But the 22-year-old felt sad when he saw the scars and wounds on the bodies of the little creatures.

“I can imagine how they have suffered from being abandoned. They lead a harsh life wandering around,” said the student..Shi is one of a dozen students at the university volunteering to feed the stray cats during the winter break.

Recruited by the Stray Cat Rescue Association at the university through a Bulletin Board System (BBS), he took turns with other students to care for the homeless animals. It is estimated that there are more than 100 stray cats on the campus of Peking University.

Jin Jing, 18, an economics freshman at the university, cared for the cats for two days. “At around 5 pm I cycled to the 22 feeding sites on campus marked on a special map,” she said. “At each site I left some cat food and water.”Jin was excited when the animals rushed to her feet. “Some are shy and timid, and others are more outgoing. Each of them has their own name such as ‘Sweet Orange’ or ‘Karl Marx’,” she said. “By feeding them I learned to respect life.”

Liu Chenhao, a senior electronics and computer science major, who is in charge of the association, said that feeding was just one part of their responsibilities.“Our aim is to keep the stray cats in check and maintain harmony between them and the students on campus,” he said.

The organization also takes cats to the animal hospital to be treated for oral and skin disease. Another of its major tasks is to find new homes for the cats by uploading their photos and information online.

“We’re very careful when selecting owners and ask them lots of questions to ensure that they won’t desert their cat under any circumstances, such as when they move house or get married,” Liu said. But he stressed that their acts of kindness shouldn’t encourage anyone to abandon their cat. “A cat’s normal life expectancy is more than 10 years, but a stray one may survive for only two or three.”  (365words)

  Both warm-blooded and cold-blooded desert animals have ways to escape the desert heat. Warm- blooded desert animals, such as rats and mice, rest during the day, often staying in cool underground burrows. At night they search for food. Animals that are out during the day, such as cold-blooded lizards and snakes, are active only for short periods. As their body temperature rises, these reptiles(爬行动物) move into the shade in order to cool down. In the early evening, when the sun grows weaker, the reptiles become more active and begin their search for food again.

  Getting enough water to survive is a major problem for all desert animals. Some desert animals, like desert birds, manage to find water holes. Other desert animals, such as the kangaroo rat and the related jerboa, get water only from the food that they eat. Because these animals eat mainly dry seeds, they must survive on a tiny amount of water.

  Most deserts have only a small number of frogs and toads because these animals must be near water to survive. Yet even these creatures have adapted(适应) to desert conditions. When small amounts of water collect in temporary streams, the desert-living frogs and toads become active. After a rainfall, they lay their eggs. The eggs grow into tadpoles in a few days and into adults in just four weeks. When the puddles(水坑) dry up, the adult frogs or toads dig into the ground. Their metabolism(新陈代谢) slows, and they stay beneath the ground until the next rain, which may be as good as a year away. Until then, their bodily activities continue at a reduced rate.

  The camel ― often called the ship of the desert ― is one of the most successful desert animals. Camels can go for long periods without water, but eventually they must drink. When water becomes available to them after a long drought, they may drink 95 liters of water or more. When water is not available, what helps camels survive the desert heat is the fat stored in their humps(驼峰). A camel’s hump contains about 12 kilograms of fat. Fat is rich in hydrogen. As the fat is digested, hydrogen from the fat combines with oxygen in the air that the camel breathes. The result is H2O, or water. Each kilogram of fat that a camel digests produces about a liter of water.

 

41. Desert animals are usually more active at night because _____.

 A. it is cooler at night        B. it is easier to find water

 C. they like the dark         D. they are less likely to be attacked at night

42. Which of the following desert animals can get water only from the food?

 A. The camel.     B. The kangaroo.     C. The frog.    D. The rat.

43. Which of the following is TRUE according to the passage?

 A. All the desert animals rest during the day.

 B. All the desert animals don’t rest during the day.

 C. Cold-blooded desert animals are out most of the day.

 D. None of the cold-blooded desert animals go out during the day.

44. The title for this passage could probably be _____.

 A. Hot Deserts                            B. Desert Animals

 C. How Desert Animals Get Water            D. Ways To Escape the Desert Heat

45. The underlined word “burrows” in the first paragraph can be replaced by _____.

 A. holes        B. caves       C. rooms        D. openings

Two out of every five species on the planet that have been estimated by scientists face extinction. This figure comes from the latest World Conservation Union Red List of Endangered Species, published this week.

In all, 16,119 animal and plant species are in danger of extinction. “From the poles(地球的两个极点) to the desert, species loss is increasing, not slowing down”, says IUCN director-general Achim Steiner. The main cause, as ever, is people, both directly and indirectly. While hunting and habitat(栖息地) loss continue to have a serious effect on species numbers, global warming is another threat.

In the polar regions (极地),the summer sea ice that polar bears depend on is rapidly disappearing, and the latest estimates suggest that the ice will be reduced at least by fifty percent in area over the next century. Although polar bears are strong swimmers, yet large numbers of them will starve or drown as global warming melts the Arctic’s ice sheets. The world’s deserts may be expanding, but the animals that live in and around them are not faring well. It’s particularly difficult for the endangered species of the extreme habitat to recover their numbers. Meanwhile, our increasing demand for fish and water is placing the species in rivers and oceans in great danger. As shallow-water fish stocks get reduced, fishermen’s dropping nets and lines into deeper waters are taking their toll on species there.

“This trend can’t be stopped. Environmentalists alone can not save the world’s species in danger”, says Steiner, “but conservation (保护) can work. It must become the responsibility of everyone to act”.

1 All the following statements are the causes of animal extinction except ______.

  A. hunting and habitat loss

  B. increasing demand for fish and water

  C. the expanding of world’s deserts

  D. global warming

2. According to the passage, which of following statements is TRUE?

  A. Only the species of the poles and deserts are facing extinction.

  B. As a result of the globe warming, polar bears will get more food.

  C. Fishermen’s fishing in deep oceans increases the toll of species.

  D. It will not take a long time for species of extreme habitat to recover their number.

3. What’s the best title of the passage?

  A. Serious Effects of Global Warming on Species

  B. More and More Animal Species Face Extinction

  C. The Endangered Species

  D. Save the World’s Species in Danger
