题目列表(包括答案和解析)

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

阅读理解

　　Due to climate change, Arctic(北极的)ice is breaking up earlier in the spring, and its area is decreasing．This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay．

　　Polar bears off Alaska normally hunt and raise their young on ice sheets(大冰原)that float on the ocean．But as the ice has melted, the polar bears have been forced to spend more time on land．There, they have begun to frequent(常去)beaches, feeding on the remains of whales caught by native hunters．For polar bears, this food is less nutritious(有营养的)than seals that they normally catch on ice sheets．The shrinking(减少)ice has also forced more polar bears into the ocean．In the past, they only had to swim short distances between ice sheets．But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean．This poses(造成)a severe danger during bad weather, and an increasing number of drowned(溺水的)polar bears have been observed．

　　In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago．Polar bears on Hudson Bay fast(绝食)during the summer, waiting for ice to form in the fall to hunt．Every year, the summer gets longer, and the bears get skinnier．Over the past 25 years, the average weight of the female bears has dropped 68 kg．This loss affects their ability to reproduce, and already the number of births has dropped 15 percent．Unless the bears can learn to survive these climate changes, these large animals of the ice may one day disappear．
