[综合性] Ⅰ.阅读理解 A The sun rises above the Arctic Ocean (北冰洋). Across the frozen sea, a white bear moves slowly. The bear stops and sways 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 is swimming. He silently walks towards the hole, then stops, standing still. The whale does not see the bear, whose white fur makes him appear invisible against the ice. Finally, the whale swims close to where the bear is waiting. With terrifying speed, the bear comes to life and moves towards 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 about a hundred thousand years ago. No one knows for sure why these bears travelled 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 used to their new environment. Their bodies changed. Their behaviour 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's survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore. 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 polar bear is unknown, the tale of two bears continues. As temperatures rise, grizzly bears have been spotted moving north into polar bear territory. These long­lost cousins, once forced apart by nature, are coming back together again. [语篇解读]　本文是一篇说明文。本文讲述了北极熊的祖先为适应环境而不断改变自身特征，而现在的这些特征却让北极熊陷入困境。 1．What 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.                                        D．It has good eyesight. 解析：C　[推理判断题。根据第四段中的“In a moment it is over, and the bear eats his first meal in nearly a week.”可知，这头熊吃了近一周以来的第一顿饭，可见它非常饥饿。因此，关于前四段提到的白熊，可以推断出“它快饿死了”。故选C。] 2．What do we know about polar bears' ancestors? A．They were a darker coloured species. B．They were born to live in ice and snow. C．They had no trouble getting used to the icy north. D．They came to the Arctic Ocean about 1,000 years ago. 解析：A　[细节理解题。根据第五段中的“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.”可知，最早的北极熊不是白熊，是棕熊，包括灰熊，颜色要深一些。因此，北极熊的祖先是一种皮毛颜色较深的物种。故选A。] 3．Why are polar bears struggling to survive? A．They are losing their hunting ground. B．They are threatened by other animals. C．They are spending little time on land. D．They have difficulty reaching the shore. 解析：A　[推理判断题。根据倒数第二段中的“Sadly, these characteristics may now threaten the polar bear's survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore.”可知，随着气候变暖，北极熊可以狩猎的冰面范围在逐渐减少，使它们生存面临威胁。因此，北极熊挣扎着生存的原因是它们正在失去猎场。故选A。] 4．Which of the following can be the best title for the text? A．The climate change B．The polar bear's favourite meal C．The dark past of the polar bear D．The mysteries of the Arctic Ocean 解析：C　[主旨大意题。通读全文，尤其是根据第五段中“The first Arctic bears were brown bears, a species that includes grizzly bears.”第六段中“No one knows for sure why these bears travelled to such a cold place. Scientists think they might have wandered north looking for food.”和倒数第二段中的“Sadly, these characteristics may now threaten the polar bear's survival. As sea ice melts due to global warming, polar bears are frequently forced to come ashore.”可知，北极熊的祖先皮毛颜色更深，它们可能是为了寻找食物而来到北极，为适应环境而不断改变自身特征。由于全球变暖，海冰融化，北极熊生存面临威胁，文章暗含北极熊误入北极的黑暗的过去。因此，文本的最佳标题是C项“The dark past of the polar bear(北极熊的黑暗过去)”。故选C。] B In a world on fire and underwater, scientists have announced some good news: Several important tuna(金枪鱼) species have stepped back from the edge of extinction. Two bluefin tuna species, a yellowfin, and an albacore are no longer seriously endangered or have moved off the leading international list of endangered species entirely. The unexpectedly fast recovery speaks to the success of efforts over the past decade to end overfishing. But tuna are not the only species scientists are thinking carefully at the 2021 World Conservation Congress in Marseille, France, which is organised by the International Union for Conservation of Nature(IUCN). Researchers warn that many other sea species continue to be imperiled . For example, more than a third of the world's sharks are still threatened with extinction due to overfishing, habitat loss, and climate change. “I think the good news is that the sustainable(可持续的)fishing industry is possible，” says Beth Polidoro, a biologist at Arizona State University. “We can eat fish without reducing the population to the point where it is on the road to dying out or extinction.” At the same time, she warns that the recovery should not encourage us to catch as many fish as we want. “We need to keep doing what's working.” Polidoro adds. The IUCN, which determines the world's most endangered species on its Red List of Threatened Species, also announced at the meeting that some animals are moving in the other direction, onto the Red List. Like the Komodo dragon, a lizard (蜥蜴), it is at particular risk from climate change. Of course, the work of protection is never over, and it will require close and continuous attention to make sure neither tuna nor Komodo dragons return to the edge of dying out. But for now, people can celebrate a few wins for the animal world. [语篇解读]　本文是一篇应用文。文章主要介绍了以金枪鱼为例子的一些物种的种群数量正在恢复，但是仍有很多其他物种濒危，我们应该继续努力。 5．What is the good news about tuna? A．They have been removed from the list of endangered species. B．The fishing of tuna has been put to an end completely. C．The population of some tuna species has recovered. D．The number of some tuna species increases slowly. 解析：C　[细节理解题。由第一段中“Several important tuna(金枪鱼)species have stepped back from the edge of extinction.”可知，几个重要的金枪鱼物种已经从灭绝的边缘退了回来。也就是说，一些金枪鱼的种群数量开始恢复。故选C。] 6．What does the underlined word “imperiled” in Paragraph 3 mean? A．Dangerous.　　　　　 B．Sustainable. C．Disappointing. D．Endangered. 解析：D　[词义猜测题。由画线词后文“For example，more than a third of the world's sharks are still threatened with extinction due to overfishing，habitat loss，and climate change.(由于过度捕捞、栖息地丧失和气候变化，世界上超过三分之一的鲨鱼的种群数量仍面临灭绝的威胁)”可知，还有其他海洋生物仍有濒临灭绝的危险。由此推知，画线词imperiled的意思是“濒危的”，与endangered意思相同。故选D。] 7．What can we learn from Beth Polidoro's words? A．We can fish tuna as much as we want. B．Protecting tuna is a long way to go. C．We shouldn't encourage tuna fishing. D．The population of tuna will reduce. 解析：B　[推理判断题。由第四段中“We need to keep doing what's working.(我们需要继续做有效的事情)”可知，这个科学家认为我们要接着实施那些有效的措施，即保护金枪鱼还有很长的路要走。故选B。] 8．Why does the writer mention “the Komodo dragon” in Paragraph 5? A．To introduce a topic. B．To make a comparison. C．To explain an idea. D．To give an example. 解析：D　[推理判断题。由第五段中“The IUCN，which determines the world's most endangered species on its Red List of Threatened Species, also announced at the meeting that some animals are moving in the other direction, onto the Red List.(世界自然保护联盟在其濒危物种红色名录中确定了世界上最濒危的物种，并在会议上宣布，一些动物正朝着另一个方向移动，进入红色名录)”可知，作者提到这种蜥蜴是作为例子，目的是论证一些动物正朝着另一个方向移动，进入红色名录。故选D。] Ⅱ.阅读填句 Sleep is an important part of your daily life－you spend about one­third of your time doing it. Quality sleep－and getting enough of it at the right times－is as important to survival (生存) as food and water. 1 Avoid caffeine, alcohol, nicotine(尼古丁) As any coffee lover knows, caffeine can keep you awake. So avoid caffeine (found in coffee, tea, chocolate, cola, and some pain relievers) for four to six hours before bedtime. 2 Create a good sleeping environment 3 To achieve such an environment, use heavy curtains, blackout shades, or an eye mask to block light, a powerful cue that tells the brain that it's time to wake up. Keep the temperature comfortably cool－between 15℃ and 23℃. And make sure your bedroom is equipped with a comfortable pillow. Set up a good pre­sleep habit Take a bath, read a book, watch television, or practise relaxation exercises. 4 If you tend to take your problems to bed, try writing them down－and then putting them aside. 5 Staring at a clock in your bedroom, either when you are trying to fall asleep or when you wake in the middle of the night, can actually increase stress, making it harder to fall asleep. Turn your clock's face away from you. A．Set an alarm clock B．Don't be a nighttime clock­watcher. C．Here are some scientific findings about sleep. D．Here are some simple tips for making the sleep well a reality. E．A quiet, dark and cool environment can help improve sound sleep. F．Avoid stressful activities－doing work, discussing emotional things. G．Similarly, smokers should stop using tobacco (烟草)products too close to bedtime. [语篇解读]　这是一篇说明文，讲述了如何获得好的睡眠。 1．D　[关联逻辑法解题。根据上文“Quality sleep－and getting enough of it at the right times－is as important to survival (生存) as food and water.”并结合下文可知，设空处应该是获得好睡眠的建议。故选D。] 2．G　[词汇锁定法解题。上句提到avoid caffeine，呼应小标题，G项提到“禁止吸烟”，呼应小标题Avoid caffeine，alcohol，nicotine(尼古丁)中的nicotine。故选G。] 3．E　[设题位置法解题。根据小标题Create a good sleeping environment可知，这一部分主要是讲营造好的睡眠环境，比较选项可知，E选项是说好的环境对睡眠的重要性，符合语境。故选E。] 4．F　[关联逻辑法解题。由上句“Take a bath，read a book，watch television，or practise relaxation exercises.”可知，应做些睡前放松的活动，也就是不做增加压力的事。故选F。] 5．B　[设题位置法解题。此处是小标题，概述最后一段的内容。由“Turn your clock's face away from you.”可知B选项“不做晚上盯着钟表的人”符合语境。故选B。] Ⅲ.语法填空 Earthquakes are quite common. In fact, earthquakes 1. (happen) almost at every moment. 2. , most of them are too weak to feel. During a big earthquake, there is often a big noise first. Then the earth shakes 3. (terrible) and many houses fall down. As one of the most deadly 4. (nature) disasters in the world, the earthquake often results in many people being injured or killed. In 2008, a severe earthquake hit China's Sichuan Province, 5. (kill) more than 60,000 people there. Besides the great damage and 6. (death) caused by the earthquake, other accidents such 7. fires often follow. More buildings may be damaged and more 8. (injure)may be caused. For centuries, people have been making studies of earthquakes. About 2,000 years ago, for example, a Chinese scientist 9. (name) Zhang Heng invented a machine which could find out the direction 10. the earthquake waves came. [语篇解读]　本文是一篇说明文。文章主要讲述了地震经常发生以及地震还会造成其他伤害等。 1．are happening　[考查动词的时态。根据句意“事实上，地震几乎每时每刻都在发生”可知，用现在进行时。故填are happening。] 2．However　[考查副词。空格前的“地震几乎每时每刻都在发生”与空格后的“大多数时候震感太弱而几乎感觉不到”之间形成转折关系。故填however。] 3．terribly　[考查副词。用副词terribly修饰动词shakes。故填terribly。] 4．natural　[考查形容词。用形容词natural修饰名词disasters。故填natural。] 5．killing　[考查非谓语动词。空格前的主语a severe earthquake与kill之间是主动关系，应用现在分词killing。故填killing。] 6．deaths　[考查名词。death是可数名词，此处用复数deaths。故填deaths。] 7．as　[考查固定搭配。such as例如。故填as。] 8．injuries　[考查名词。injure的名词形式是injury，injury是可数名词，此处应用复数形式injuries。故填injuries。] 9．named　[考查非谓语动词。a Chinese scientist与name之间是被动关系，应用过去分词。故填named。] 10．where　[考查定语从句。先行词为the direction，关系词在后面的定语从句中作地点状语，故用where引导定语从句。故填where。] 学科网（北京）股份有限公司 $$
