Ⅰ. 阅读理解

A

　　More than two thirds of the world ’s polar bears will be wiped out by 2050,  according to a shocking new study. By then,  scientists say,  global warming will have melted 42 percent of the Arctic sea ice. By 2100,  only a very few of these important creatures will be left.

The report has been produced by the US Geological Survey. The scientists have publicized their findings in the hope of influencing US Interior Secretary Dirk Kempthorne,  who has been asked to put polar bears on the US endangered species list.

Polar bears depend on floating sea ice as a platform for hunting seals,  which are their main food. Without enough ice,  polar bears would be forced to go onto the land,  where they are poorly skilled hunters,  and would be unlikely to adapt to the life on the land in time. Experts say few little bears would survive and the stress could make many females unable to get pregnant.

The team of American and Canadian scientists spent six months studying bears,  on the ground,  from spotter planes and in the lab, using computer models. Some team members fear the result is even worse for the bears than what their report says. They say the Arctic is warming faster than anywhere in the world and much faster than their computer had been forecasting. Satellite observations have showed that the ice has decreased to an all-time low.

However,  not everyone in the scientific community believes that global warming is happening on such an alarming scale. Another investigation has found that polar bears are still being hunted by wealthy “sportsmen” who want their skins and heads. At least ten international companies offer bear-hunting trips.

【文章大意】本文是一篇说明文。本文说的是由于全球变暖, 北极熊有可能在这个世纪末就要灭绝了。

A. He is an animal scientist.

B. He is a protector of animals working for the US government.

C. He was asked to put polar bears on the US endangered species list.

D. He offered to put polar bears on the endangered species list.

【解析】选C。细节理解题。根据第二段第二句中的“US Interior Secretary Dirk Kempthorne,  who has been asked to put polar bears on the US endangered species list. ”可知, 他被要求把北极熊列入美国濒危物种名单, 故选C。

2. Why will polar bears die out if there is not enough sea ice?

A. Because polar bears can ’t catch enough food without ice.

B. Because polar bears eat ice when they feel thirsty.

C. Because polar bears will be easily found by hunters without ice.

D. Because most female bears are used to giving birth under ice.

【解析】选A。细节理解题。根据第三段第一句“Polar bears depend on floating sea ice as a platform for hunting seals,  which are their main food. ”可知, 如果没有足够的海冰, 北极熊会因为捕捉不到足够的猎物而濒临灭绝, 故选A。

3. After a six-month study,  some scientists fear that________.  

A. there is something wrong with their computers

B. polar bears will disappear even faster than they ever expected

C. their computer models are not as accurate as they expected

D. global warming will destroy everything in the Arctic

【解析】选B。细节理解题。根据第四段的“Some team members fear the result is even worse for the bears than what their report says. ”可知, 科学家们担心北极熊消失的速度将比他们预想的还要快, 故选B。

Thirteen years ago,  the Planet Earth wildlife documentary took us all on an amazing journey.  We went from deep rainforests to the bottom of the ocean.  Now a new one,  Our Planet,  will let us see different animals and the influence of humans on the natural world.  The documentary covers 50 countries and areas.  It took more than four years to produce it.

With the latest 4K video technology,  the show allows people a wonderful new look at nature. “People are given a chance to better get themselves into the lives of the animals, ” said Fothergill,  one of the show ’s producers.

Besides showing Earth ’s beauty,  the documentary also talks about the planet ’s climate conditions.  “Our Planet is here to say,  ‘The planet is dying,  and we ’re killing it.  ’” Fothergill said.  In one sad scene,  hundreds of walruses(海象), half-blind when out of the water,  fall down a rock and suffer a painful death on the beach below.  It shows how the climate conditions have influenced their natural habitat and explains why they ’ve been forced to find the safe place on the rocks.

But the documentary is not all about sadness.  It also talks about successful stories,  such as the ones of tigers.  These animals are saved and live happily,  thanks to international agreements on environmental protection.

Asking more people to take action in protecting our planet is the final goal of the new documentary.  What we do in the next 20 years will decide the future of all life on Earth.
