As the years pa

22、ssed and he became more passionate about this issue, he started travelling the world in order to educate people about the effects of global warming using computer slide shows. Free of charge, he explained to his audiences that the world is facing a ‘planetary emergency’ and that it isn't too late to

23、 stop it if appropriate action is taken now. It was during this time of touring and giving lectures that Gore was spotted by Hollywood producer Laurie David, who asked him to turn his slide shows into a documentary in which he would play the starring role. At first, Gore was reluctant,_as he has al

24、ways been a very private person, despite being used to being in the public eye. Eventually, though, David managed to persuade him. The result was a fascinating documentary combining references to Gore's own life story with horrifying predictions about the future of our planet. Little did Gore know

25、that just one year later he would be walking along the red carpet at the Cannes Film Festival and later collect ing an Oscar for ‘Best Documentary’. Advertised as ‘the scariest movie you'll see，’ the movie concentrates on the potentially terrifying consequences of climate change. ‘An Inconvenient

26、Truth’ certainly gives us much to consider. As the title of the film suggests, it may be inconvenient for us to have to think about the future of the planet, but think we must. The profits from the film are now funding other campaigns to spread the message about global warming. Gore is delighted th

27、at some schools are even using the DVD to help them teach awareness of environmental issues to their students. So can this one man's efforts really make a difference? Well, according to Gore, if we are clear about what the problem is, then we are more likely to introduce changes into our daily live

30、 mean? A．Cheerful.　　　　　　　 B．Curious. C．Surprised. D．Unwilling. 解析：選D　詞義猜測題。根據(jù)下文中的“as he has always been a very private person”和“Eventually, though, David managed to persuade him.”可知，Gore一開始并不愿意接受好萊塢制片人Laurie David的提議。 3．What can we infer about the film? A．It was a great success. B．It brought

31、 Gore in great money. C．It was far too scary for many people.

Across the frozen sea, a wh

34、ite bear moves slowly. The bear stops and sways (搖晃) his head from side to side. There is nothing to see but endless ice and red sky. Then his powerful nose senses what his eyes cannot: a beluga whale is nearby. The bear follows the smell and spots a large hole in the ice where a small white whale

35、 is swimming. He silently walks toward the hole, then stops, standing still. The whale does not see the bear, whose white fur makes him appear invisible (看不見的) against the ice. Finally, the whale swims close to where the bear is waiting. With terrifying speed, the bear comes to life and moves towar

36、d the whale. In a moment it is over, and the bear eats his first meal in nearly a week. Polar bears rule the frozen sea, but their ancestors weren't always built for ice and snow. The first Arctic bears were brown bears, a species that includes grizzly bears. They came to the icy north over a hundr

37、ed thousand years ago. No one knows for sure why these bears traveled to such a cold place. Scientists think they might have wandered north looking for food. Maybe they became trapped by glaciers and couldn't leave. Whatever the reason, the bears never should have survived. But they did. They got

38、used to their new environment. Their bodies changed. Their behavior changed, too. Eventually, the bears developed into an entirely new species: the polar bear. You can see some of the characteristics that polar bears developed to survive. Sadly, these characteristics may now threaten the polar bear

39、's survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore (在岸上). They are poor hunters on land, which means they often go a long time between meals. The polar bear, king of the Arctic, is now classified as a threatened species. Although the future of the

40、polar bear is unknown, the tale of two bears continues. As temperatures rise, grizzly bears have been spotted moving north into polar bear territory (領(lǐng)地). These long-lost cousins, once forced apart by nature, are coming back together again. 語篇解讀：本文是一篇說明文。北極熊的祖先為適應(yīng)環(huán)境而不斷改變自身特征，而現(xiàn)在這些特征卻讓北極熊陷入困境。 5．Wh

41、at can be inferred about the white bear mentioned in the first four paragraphs? A．It is noisy. B．It is smelly. C．It is starving.

45、st title for the text? A．The climate change B．The polar bear's favorite meal C．The dark past of the polar bear D．The mysteries of the Arctic Ocean 解析：選C　標題歸納題。文章講到北極熊的祖先毛皮顏色更深，C項中的The dark past既表明了北極熊祖先的外表特征，也暗含它們過去誤入北極的歷史。 Ⅱ.完形填空 I was walking in a park on a cool autumn morning.The view was
