Certain areas, such as California and Japan, are more prone__to earthquakes than others. Although the chance of being caught in “The Big One” is remote, it's wise to be prepared if you live in a region where earthquakes are common. 课后课时作业（五） 50 Educate your family about earthquakes before a big one strikes. For example, they need to know to take shelter in a doorway or under a strong object if indoors, and never to run outdoors if they are inside. If outside, they need to know to stay away from power lines and buildings where objects could fall. Teach family members how to turn off gas or water lines or electrical power that may need to be shut off after a quake if severe damage occurs. Develop a plan. Where will your family meet in the event of a disaster? What if some people are at work or school? How will you know if they are safe? Where will you all meet up? 课后课时作业（五） 51 Pack a preparedness kit (衣物装备) and keep it in a safe location. In a major earthquake, it's possible that you won't be able to get into your house. Keep supplies in your car trunk or an outside storage shed if possible. Pack whatever your family is likely to need, enough for three days to a week, including food, water, medication, first aid and personal hygiene supplies, flashlights, a portable radio, blankets, clothes and shoes, cash, or camp stove, candles, matches or lighters, and a whistle. 课后课时作业（五） 52 篇章导读：本文是一篇说明文。文章讲述了每年的地震很多，但是大地震并不多，经常遭受地震的地区也是集中的，但是我们应该为地震做好准备，尽量减少损失。 篇章导读 Consider earthquake insurance for your home if you live in an earthquake­prone area. Regular homeowner's insurance doesn't cover earthquake damage. 课后课时作业（五） 53 1．The underlined phrase “prone to” in Paragraph 1 can be replaced by ________．(　　) A．likely to suffer B．frequent to explore C．regular to measure D．impossible to experience 解析：词义猜测题。根据最后一段可知，如果你住在地震多发区，要考虑为你家购买地震保险，因为常规房屋保险不保障地震损害。因此可推断，prone to意为“可能会遭受”。故选A。 答案 解析 课后课时作业（五） 54 2．According to the passage, if you are outside in an earthquake, you should ________．(　　) A．stay where you are B．hide under a big tree C．avoid power lines D．sit on the ground 解析：细节理解题。根据第二段最后一句可知，地震的时候如果你在外面，应该避开电线。故选C。 答案 解析 课后课时作业（五） 55 3．We can learn from the passage that ________．(　　) A．about 1，500 earthquakes happen every year B．people should store some clothes in their houses in advance C．family members should meet in their home after an earthquake D．people suffering earthquakes often should buy earthquake insurance 解析：细节理解题。根据最后一段可知，家住震区的人应该买地震保险。故选D。 答案 解析 课后课时作业（五） 56 4．What would be the best title for the passage？(　　) A．How to Keep Safe in an Earthquake? B．How to Prepare for an Earthquake? C．Who Can Help US After an Earthquake? D．Where Is an Earthquake­Prone Area? 解析：标题判断题。第一段最后一句提到“Although the chance of being caught in ‘The Big One’ is remote, it's wise to be prepared if you live in a region where earthquakes are common.”以及其他各段都围绕着这一句展开，由此可知，这篇文章讲的是如何为地震做好准备。故选B。 答案 解析 课后课时作业（五） 57 B When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure (压力) produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains. 课后课时作业（五） 58 Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable (急躁的) and quarrelsome and will fight over a piece of bread. Other birds chirp (叽叽喳喳) and sing just before a storm. It seems that they know they won't get another chance for an hour or two. Birds also seek safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre­storm low pressure makes the air so thin that birds have difficulty flying. 课后课时作业（五） 59 篇章导读：本文是一篇说明文。文章主要讲述了动物，如老鼠、鹿、小鸟在天气变化前的不同反应。 篇章导读 It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm. By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather. 课后课时作业（五） 60 5．The underlined word “indicators” in Paragraph 1 probably means “________”．(　　) A．maps B．services C．signs D．stations 解析：词义猜测题。作者在第一段中首先指出人们可以通过观察野生动物来了解天气状况，接着给出原因，然后举例“Mice and deer are good weather indicators．”，由此可推知，indicator意为“标志，迹象”。故选C。 答案 解析 课后课时作业（五） 61 6．There will be a storm if birds ________．(　　) A．make more noise than usual B．fly in different directions C．come down from tall trees D．share a piece of bread 解析：细节理解题。根据第二段中的“irritable (急躁的)” “quarrelsome” “chirp (叽叽喳喳)”和“sing”等词可知，如果鸟儿比平时发出更多的噪音，说明暴风雨将要来临。故选A。 答案 解析 课后课时作业（五） 62 7．How can birds sense the coming of a storm？(　　) A．By feeling a drop in air temperature. B．By noticing the change of wind directions. C．By feeling a drop in air pressure. D．By noticing the movements of other animals. 解析：细节理解题。根据第二段的首尾句中的“a pressure drop” “low pressure”可知，鸟儿通过感受气压的下降，从而感知到暴风雨的来临。故选C。 答案 解析 课后课时作业（五） 63 8．The best title for the text would be “________”．(　　) A．Signs of a Storm B．Drops in Air Pressure C．Animals' Sharp Senses D．Nature's Weather Signs 解析：标题判断题。文章主要讲述了动物敏锐的感知能力。故选C。 答案 解析 课后课时作业（五） 64 C Climate change, not human hunting, may have destroyed the thylacine (袋狼), according to a new study based on DNA from thylacine bones. The meat­eating marsupials (有袋动物) died out on mainland Australia a few thousand years ago, but survived in Tasmania, an island of southeast Australia separated from the mainland, until the 1930s. Until now, scientists have believed the cause of this mainland extinction (灭绝) was increased activity from native Australians and dingoes (Australian wild dogs)． 课后课时作业（五） 65 Scientists behind the University of Adelaide study, which was published in the Journal of Biogeography, collected 51 new thylacine DNA samples from fossil bones and museum skins. The paper concluded that climate change starting about 4，000 years ago was likely the main cause of the mainland extinction. The ancient DNA showed that the mainland extinction of thylacines was rapid, and not the result of loss of genetic diversity (基因多样性). There was also evidence of a population crash in thylacines in Tasmania at the same period of time, reducing their numbers and genetic diversity. 课后课时作业（五） 66 Professor Jeremy Austin said Tasmania would have been protected from mainland Australia’s warmer, drier climate due to its higher rainfall. He argued that climate change was “the only thing that could have caused, or at least started, an extinction on the mainland and caused a population crash in Tasmania.” “They both occurred at about the same time, and the other two things that have been talked about in the past that may have driven thylacines to extinction on the mainland were dingoes and humans. So the only explanation that's left is climate change. And because that population crash happened at the same time that the species (物种) went extinct on the mainland, our argument is that there's a common theme there and the only common theme is that there is this change in climate.” 课后课时作业（五） 67 篇章导读：本文是一篇说明文。文章介绍了气候变化可能是导致袋狼消失的原因。 篇章导读 课后课时作业（五） 68 9．What did scientists believe in the past according to the passage？(　　) A．Marsupials were all meat­eating animals. B．Dingoes should be removed from Australia. C．Thylacines had no enemies on mainland Australia. D．Human activities may cause the extinction of thylacines. 解析：推理判断题。根据第二段第二句可知，到目前为止，科学家们一直认为大陆物种灭绝的原因是澳大利亚土著居民和澳洲野狗活动的增加。由此可推知，科学家过去认为人类活动可能会导致袋狼的灭绝。故选D。 答案 解析 课后课时作业（五） 69 10．What's the difference between mainland Australia and Tasmania？(　　) A．Tasmania has more dingoes. B．Tasmania has more rainy days. C．Tasmania has a higher temperature. D．Tasmania has more native activities. 解析：细节理解题。根据倒数第二段第一句可知，塔斯马尼亚可以免受澳大利亚大陆更温暖、更干燥的气候的影响，因为那里的降雨量更多。即塔斯马尼亚有更多的雨天。故选B。 答案 解析 课后课时作业（五） 70 11．The reason why Jeremy Austin had strong argument is that ________．(　　) A．something similar occurred on mainland Australia and Tasmania B．Tasmania was protected from mainland Australia's warmer climate C．humans and dingoes may have driven thylacines to extinction D．mainland Australia suffered from much higher rainfall in the past 解析：推理判断题。根据倒数第二段中的“He argued that climate change was ... crash in Tasmania.’”和最后一段中的“that population crash happened ... on the mainland”可推知，澳大利亚大陆和塔斯马尼亚岛发生了类似的事情。故选A。 答案 解析 课后课时作业（五） 71 12．What's the best title for the passage？(　　) A．The cause of disappearance of thylacines B．The ways of protecting meat­eating animals C．The result of warmer climate in Australia D．The effect of climate change on wildlife 解析：标题判断题。通读全文可知，这篇文章讲述了气候变化可能是袋狼消失的原因。A项(袋狼消失的原因)最适合作为文章标题。故选A。 答案 解析 课后课时作业（五） 72 D Rivers are very important. Humans rely on them for food and water. But rivers can destroy things, too. They can flood, or rise over their banks, making the water run into the nearby land. Floods can also kill humans and wildlife. However, floods are not always bad. Some ecosystems need them every once in a while. 课后课时作业（五） 73 Flooding can not only drown animals but also destroy habitats. For example, a flood in India in 2012 killed many one­horned rhinos. Flood waters can pick up dirt from riverbanks, which makes the water dirty. Too much dirt will clog rivers and streams, preventing the river from flowing. Sometimes flood waters can carry pollution to the sea and harm marine life. In addition, flood waters can carry disease, including hepatitis A and cholera. 课后课时作业（五） 74 However, not everything about floods is bad. Sometimes they bring new life to ecosystems. Flood waters carry nutrients to the nearby land. Over time, the water dries up and leaves behind particles (微粒) of dirt and mud. The particles are called sediment (沉淀物) which can be good due to its ability to improve the dirt and help plants grow. Floods are important to some animals as well. For instance, some animals see floods as a sign that it is time to mate or migrate. Floods leave sediment on river beds where baby fish can grow and carry nutrients for small animals in the water to eat. Moreover, in dry seasons, water might dry up, but floods help refill the wetlands, keeping the ecosystem going. 课后课时作业（五） 75 篇章导读：本文是一篇说明文。文章主要介绍了作为大自然的一部分，洪水对于生态系统既有好处也有坏处。 篇章导读 Floods are a part of nature. They can destroy living things and the environment. But some ecosystems need floods to survive. 课后课时作业（五） 76 13．What's the possible meaning of the underlined word “clog” in Paragraph 2？(　　) A．Become. B．Pollute. C．Block. D．Develop. 解析：词义猜测题。根据第二段中的“Too much dirt will clog rivers and streams, preventing the river from flowing.”可知，太多的泥土会堵塞河道，阻止河水流淌。由此可推知，clog意为“堵塞”。故选C。 答案 解析 课后课时作业（五） 77 14．How do floods help ecosystems？(　　) A．Nutrients carried by floods can make soil richer. B．Floods make all the animals migrate more easily. C．Tiny fish going with floods feed some animals. D．Floods can improve the dirt and help plants grow. 解析：细节理解题。根据第三段中的“However, not everything ... plants grow.”可知，洪水沿途携带的营养物质可以使土壤更肥沃。故选A。 答案 解析 课后课时作业（五） 78 15．What's the main idea of Paragraph 3？(　　) A．The way in which floods feed animals. B．The benefits of floods to ecosystems. C．An effective means of improving soil. D．The reason for people's appreciating floods. 解析：段落大意题。根据第三段中的“However, not everything ... new life to ecosystems.”及下文描述可知，第三段主要讲述洪水对于生态系统的好处。故选B。 答案 解析 课后课时作业（五） 79 16．What's the best title of this article？(　　) A．The Bad Effects of Flooding B．The Secret of Flooding C．Floods—a Disaster to Humans D．Floods—a Part of Nature 解析：标题判断题。通读全文可知，文章前三段主要讲述洪水对于生态系统有好处也有坏处。最后一段总结全文，点明主题——洪水是大自然的一部分。所以D项(洪水——大自然的一部分)最适合作为文章标题。故选D。 答案 解析 课后课时作业（五） 80 Ⅱ　完形填空 Steven Callahan was crossing the Atlantic alone in his sailboat when it struck something and sank.
