阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。

A

The survival of about one fifth of the world's vertebrates—animals with a

backbone，is considered threatened, according to new research published in the

journal Science. That's a large fraction of Earth's animals, but this new study held

some good news too. Conservation efforts by humans have slowed the loss of many

species of amphibians(两栖动物), birds, and mammals. Losses in these groups would

have been about 20 percent greater had it not been for recent actions of protection.

Among the animal­conservation success stories is one about birds called

Mauritius kestrels. In the 1970s, just four of these birds of prey were left in the

world. Through a special breeding program, scientists were able to increase their

number to about 1,000 and release them into the wild.

Humpback whales(座头鲸) have benefited greatly from recent conservation efforts

as well. They were once on the International Union for Conservation of Nature's

(IUCN)list of species threatened with extinction. But the species is now in less

danger, thanks to laws that ban whale hunting. The IUCN even moved the humpback into

“species of least concern.”

Over the past 100 years, the white rhino(犀牛) of South Africa has also made

an amazing recovery because of habitat protection. The breed multiplied from just

50 animals to about 17,000. Their home has been turned into a protected area, safe

from poachers and other threats.

Stuart Butchart, one of the authors of the new study in Science, is encouraged

by the positive effects of conservation. But he says “Biodiversity (生物多样性)of

species is in a desperate state. Its situation is getting worse. But our results

show we can turn the situation around.”

New conservation policies hopefully are on the way. One hundred ninety­three

countries recently met in Japan at the Convention on Biological Diversity to set

concrete goals for preserving threatened wildlife and their habitats. Only 1 percent

of oceans and 12 percent of land areas were protected under prior agreements. Two

new goals set by the group are to designate(指定) 10 percent of the world's oceans 优质资料\word可编辑

endangered­animal populations.

kestrels didn't increase.

B．Conservation efforts should not only be made by human beings.

C．Humpback whales are not on the International Union for Conservation of

Nature' s list now.

D．Because many groups are working to protect wildlife, natural habitats are

in

good condition.

22．Which of the following is NOT mentioned in people' s conservation efforts?

A．Habitat protection.

B．Breeding programs.

C．Laws of banning whale hunting.

D．Creation of studying organizations.

23. The author uses some successful animal­conservation examples to show

that________.

A．conservation works

B．man conquers nature

C．animals are more important

D．law is fair

It was a Sunday and the heavy storm had lasted all night. The morning after

the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea

touching the shore gently.

My father realised it was a good day for fishing and invited my sister and me

to go with him. I was only 14 and fishing had never been my thing, but I decided

to go all the same. I' m so glad I did.

On the road to the harbour we could see the terrible destruction on the coast,

but the harbour itself was in fairly good shape. After all, it was protected by the

arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed

two big humps (脊背) in the distance. 优质资料\word可编辑

3 / 93 On approaching them, we saw it was a mother whale with her baby. We couldn't

believe it — there aren't any whales along the coast here. The storm must have driven

them across the ocean into the bay, in which the still water was so badly polluted

that nothing could survive.

The little baby whale — actually as big as our boat—was obviously stuck and

could not move. The mother dived under the water and came up suddenly, making big

whirlpools (漩涡) and waves. “She' s trying to help her baby, but on the wrong

side, ” my father said. At this point, my father moved our boat in a semicircle

to the other side and, heading the boat towards the baby whale, pushed it gently.
