[综合性] Ⅰ.阅读理解 A Every summer，the Serengeti plains (平原) of Africa are worth visiting.Millions of wild animals begin their 1,800­mile journey northwards on their annual migratory (迁移的) route. In the month of November，polar bears in their thousands cross the Canadian Arctic，as they head towards the ice sheets of Hudson Bay.The sea ice that forms every winter is the key to the bear's managing to exist，for here they hunt for seals (海豹)． The Great Bustard，one of the heaviest flying birds，migrates each year across Europe and Asia to its wintering grounds.Unluckily，these and other migratory animals are in danger from human activity. Since 1979，ice sheets(冰源) in the Arctic have gone down by 30 percent.What does this mean for polar bears？They are forced to stay on land for longer periods of time，which delays their search for food.As a result，bears today are 60 pounds lighter than what they were.Besides，smaller bears also produce weaker babies，and their chances of survival are at risk.In the plains of Africa，migratory animals like gazelles are traveling long distances for food，just to avoid falling prey (牺牲品) to humans who hunt them. In an unusual step，experts from 120 countries have agreed to protect 31 migratory mammals，fish and birds.The United Nation's 11th annual Conservation of Migratory Species of Wild Animals (CMS) was held in Quito，Ecuador.For the first time,900 experts attended the conference，and the enthusiastic support shows the world is united in conservation (保护) efforts. What does getting on a protected list mean？Countries that have signed the agreement will be required to pass laws locally and work with other countries that fall within the animal's migratory path.Only one animal did not make the list.The African lion was rejected (拒绝) for lack of information of the countries where it lives.

B．The weight of polar bears today is lighter than what it was. C．In the 1970s，ice sheets went down by 30 percent. D．120 experts have agreed to protect 21 migratory animals. 解析：B　[细节理解题。根据第四段中的“As a result，bears today are 60 pounds lighter than what they were.”可知，现在北极熊的体重比原来减少了60磅。故选B。] 2．Why was the African lion not included on the list from the passage? A．We don't know which countries it lives in. B．It isn't a migratory animal. C．Experts were not interested in this animal.

A．let us know about the animals B．prevent the rare animals from dying out C．inform us of the effects of climate change D．draw our attention to helping the migratory animals 解析：D　[写作意图题。阅读全文可知，文章介绍了很多野生动物在迁徙途中遭受人类的捕杀或受到人类活动的影响导致数量急剧下降，在联合国第11届野生动物迁徙物种年度保护大会上，专家们呼吁世界各国联合起来保护迁徙物种。由此可知本文的写作目的是引起人们的注意来帮助迁徙动物。故选D。] B In one of the world's most forbidding environments，polar bears spend their summers roaming (漫步) the Arctic on large pieces of floating ice.They drift (漂移) for hundreds of miles，finding mates，hunting for seals，and fatting themselves up for the winter.Without the floating ice，the world's largest bears could not survive.Yet at this moment，the polar bears' Arctic habitat (栖息地) is melting away under it because of global warming. Over the past three decades，more than a million square miles of floating ice has disappeared.Scientists predict that，if the current rate of global warming continues，most，if not all，of the bears' floating ice will be gone by 2100.As a result，the world's polar bears could face global dying out by the end of this century. Already，the ice on the southern edge of the polar bears' habitat is melting about three weeks earlier than in the past.The loss of those key weeks leaves the bears less time to hunt，eat and store up fat.Once the ice melts, the_bears_must_fast_for_up_to_eight_months_on_land until the floating ice returns.As a result of early melting，there has been a 14 percent decline in the Hudson Bay polar bear population over the past ten years－a fall clearly caused by global warming. Besides，a growing number of polar bears may be drowning (溺水) as they are forced to swim more often，and for longer distances，looking for ice sheets.According to a report by the US Minerals Management Service，researchers observed four dead polar bears floating 60 miles off Alaska in September of 2006 and said it was likely that many other bears swimming far off shore also drowned.Scientists have concluded that the worldwide population of about 20,000 polar bears is likely to become smaller by more than 30 percent in the next 35 to 50 years alone.
