Anyone can become a volunteer if he/she agrees to help the elephant keepers with tasks. Daily tasks Gather the elephants at 6：30 am. Take them to look for food in the forest. Clean the enclosure (围场). Swim with the elephants in the lake in the afternoon. If volunteers want to relax after work, they can watch satellite television. How this vacation helps If these elephants hadn't been rescued, they would still be living on the streets of Bangkok. The rural environment is much better for them than the urban environment where there is lots of pollution. 课后课时作业（三） 128 Gorilla safari (旅行) Countries: Kenya, Rwanda and Uganda Departures (出发)：2－3 departures per month from Aug. to Dec. If you're lucky, you'll see lions, elephants and rhinos during this safari. The highlight of the trip is the opportunity to see gorillas in the mountain forests. However, you must be in good health—if a gorilla caught a cold, it would be extremely harmful to its whole family. How this vacation helps There are only about 600 gorillas left in the world as human activity has reduced the area where they can live. When you buy a ticket, this will pay for the protection of the national park. 课后课时作业（三） 129 Polar bear watching Area & Country: Arctic, Canada Departures: sixty trips between Oct.1－Nov.19. Every October and November groups of polar bears gather in Hudson Bay. As they are normally lonely creatures, this is unusual. The bears wait for the ocean to freeze so that they can hunt for seals, so this is the perfect opportunity to see them. How this vacation helps If the Arctic ice cap melts due to global warming, polar bears will be in danger. We give a share of our profits to the charity that protects polar bears. 篇章导读：本文是一篇应用文。文章主要介绍了三个保护野生动物的活动。 课后课时作业（三） 130 1．Which of the following is the task for elephant volunteers? A．Take a bath for the elephants at 6：30 am. B．Teach the elephants to swim in the lake. C．Make sure the enclosure is clean every day. D．Watch satellite television to learn knowledge about elephants. 解析：推理判断题。根据第一栏Daily tasks部分中的“Clean the enclosure (围场)．”可知，志愿者们的任务包括打扫大象的围场，由此可推知，志愿者要确保围场每天都是干净的。故选C。 课后课时作业（三） 131 2．What do we know about the gorilla safari? A．You can set off in April to see gorillas. B．You will get a cold in mountain forests. C．To see lions in the mountain forests may be the best part of the trip. D．Human activities have made gorillas' living area smaller. 解析：细节理解题。根据第二栏How this vacation helps部分中的“There are only about 600 gorillas left in the world as human activity has reduced the area where they can live.”可知，人类活动使得大猩猩的栖息地变小了。故选D。 课后课时作业（三） 132 3．When is the best time to watch polar bears?

D．August 10. 解析：细节理解题。根据第三栏Departures部分下面的“Every October and November groups of polar bears gather in Hudson Bay.”可知，观察北极熊的绝佳时间是十月份和十一月份。故选A。 课后课时作业（三） 133 B You can see a sea turtle named Herman, an octopus (章鱼) called Octavia, and a seal named Lidia at the Smithsonian's National Zoo in Washington D．C. Rather than real animals, they are actually artworks made out of plastic trash from the ocean. These artworks are part of a travelling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by the artist called Pozzi, works to raise awareness about plastic pollution in Earth's oceans. 课后课时作业（三） 134 More than 315 billion pounds of plastic litter the world's oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. Rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. Thousands of sea animals die each year from eating plastic bags and other things. Each year, millions more pounds of plastic end up in the ocean. A recent study found that if that continues, by 2050 the total weight of plastic will be more than that of all the fish in the ocean. 课后课时作业（三） 135 篇章导读：本文是一篇新闻报道。Washed Ashore项目展览了一些用海洋里的塑料垃圾制成的艺术品，提醒人们海洋塑料污染问题的严重性及拯救海洋和保护环境的重要性。 The Washed Ashore project is working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38，000 pounds of plastic trash from more than 300 miles of beaches. They helped Pozzi create more than 60 artworks of sea creatures harmed by plastic pollution. “These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity (生物多样性) on land and in the sea，” says Dennis Kelly, director of the National Zoo. 课后课时作业（三） 136 4．What is the purpose of the artworks shown at the Smithsonian's National Zoo? A．To let people know about animals in the ocean. B．To introduce one way of recycling plastic trash. C．To warn people of plastic pollution in the ocean. D．To show Pozzi's great gift for creating artworks. 解析：细节理解题。根据第二段内容可知，展览这些垃圾制成的艺术品的目的是提醒人们海洋塑料污染问题的严重性，从而引起人们对这一问题的重视。故选C。 课后课时作业（三） 137 5．According to the passage, what is the source of plastic pollution in the ocean? A．Garbage from towns and cities. B．Trash left on beaches by people. C．Plastic bags broken up by waves. D．Litter created by human activities. 解析：细节理解题。根据第三段第二句“Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches.”可知，海洋中的塑料污染主要来自城镇垃圾和人们留在沙滩上的垃圾，即人类活动产生的垃圾。故选D。 课后课时作业（三） 138 6．The data in Paragraph 5 is given to prove that ________． A．plastic pollution will be more serious in the ocean B．more and more artworks of sea creatures will be made C．the Washed Ashore project has made great achievements D．volunteers can solve the ocean pollution successfully by 2050 解析：推理判断题。第五段的数据表明，自2010年以来，Washed Ashore项目的志愿者已经从300多英里的海滩上收集了3.8万磅的塑料垃圾。他们帮助Pozzi(波齐)创作了60多个受到塑料污染伤害的海洋生物作品。这些数字说明Washed Ashore项目取得了很大成就。故选C。 课后课时作业（三） 139 7．What's Dennis Kelly's attitude towards the artworks? A．Worried. B．Supportive. C．Doubtful. D．Unconcerned. 解析：推理判断题。根据最后一段Dennis Kelly(丹尼斯·凯利)说的话“These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity (生物多样性) on land and in the sea”可知，他认为这些艺术品提醒我们在保护生物多样性方面的个人作用和全球责任，说明了这些艺术品的重要作用，可见Dennis Kelly对这些艺术品是支持的。故选B。 课后课时作业（三） 140 C The words “protect animals” appear everywhere in books and on screens, because some animals are even in danger of dying out. But sometimes the fact can be a little different from what people read or watch. About 300 black bears were killed in Florida, the US, in October, 2015. It's been the first bear hunt in the state since 1994. Local officers explained that the black bear population had grown to 3，500 and became a menace (威胁) to local people. 课后课时作业（三） 141 In the past, the Swiss government allowed locals to kill a wolf. This was because the wolf killed 38 sheep, and it was a great loss to some local farmers. In China, three old men were caught by the police for killing a serow, a kind of protected animal. They said they killed the animal because it ate the plants they grew. However, these stories don't always mean that animal protection stops because of human interests especially when it is connected to economic development. A man named Zhou Weisen set up a wild animal base in Guilin, Guangxi. He saved over 170 tigers and about 300 bears. His base also offered jobs to local people. 课后课时作业（三） 142 篇章导读：本文是一篇说明文。文章主要介绍了不少国家为了人类利益而猎杀野生动物，专家认为我们应该兼顾动物保护和人类发展。 “There may never be a standard answer to the question of whether we should give more attention to the environment or human development，” said Robert May, a British expert at Oxford University. “But we shouldn't push either one to the side, as the future is uncertain.” 课后课时作业（三） 143 8．What can we learn from the second and third paragraphs? A．3，500 black bears were killed in Florida. B．The wolf can't be killed in Switzerland. C．The serow is protected in China. D．Three old Chinese men's loss was made up for. 解析：细节理解题。根据第三段中的“In China, three old men were caught by the police for killing a serow, a kind of protected animal.”可知，鬣羚在中国是受保护的动物。故选C。 课后课时作业（三） 144 9．What does the author intend to tell us by mentioning Zhou Weisen's story? A．Protecting animals needs great efforts. B．Protecting animals can bring economic development. C．Zhou was good at feeding wild animals. D．Zhou had a good relationship with local people. 解析：推理判断题。根据第四段中的“However, these stories don't always mean ... connected to economic development.(然而，这些故事并不总是意味着动物保护会因为人类利益而停止，特别是当它与经济发展有关时。)”可推知，举这个例子的目的是想说明保护动物的同时也可以带来经济发展。故选B。 课后课时作业（三） 145 10．Which of the following statements might Robert May agree with? A．We should pay more attention to animal protection. B．Human development should be considered first. C．It's difficult to find proper ways to solve environmental problems. D．We should consider both the environment and human interests. 解析：推理判断题。根据最后一段“‘There may never be ... as the future is uncertain.’(‘对于我们应该更加关注环境还是人类发展的问题，我们可能永远不会有一个标准的答案，’牛津大学的英国专家罗伯特·梅说。‘但我们不应该把任何一方放在一边，因为未来是不确定的。’)”可推知，他认为我们既要保护环境又要考虑人类的利益。故选D。 课后课时作业（三） 146 11．What's the best title of the passage? A．Protecting animals or killing them B．Protecting animals C．Killing some dangerous animals D．Difficulties in protecting animals 解析：标题判断题。通读全文可知，文章主要介绍了不少国家为了人类利益而猎杀野生动物，专家认为我们应该兼顾动物保护和人类发展。因此A项(保护动物还是猎杀它们)最适合作为文章标题。故选A。 课后课时作业（三） 147 D Are African wild dogs really dogs? What's the difference between African wild dogs and the dogs we know as pets? For one thing, African wild dogs, which live in Africa, only have four toes, while domestic (驯养的) dogs and wolves have five. But you won't want to count for yourself, because they are truly wild animals. 课后课时作业（三） 148 “Wild dogs are not somebody's domestic dogs that ran away and didn't come back, although some people used to think that，” explains Dr McNutt, who studies these animals at Wild Dog Research Camp in the African country of Botswana. “They are actually Africa's wolves, and just like wolves, they do not make good pets. They need to be out in the wild doing what they are supposed to do—find the food they need to survive and feed their babies.” In fact, they travel so far that researchers have to use radio collars (颈圈) to keep track of them. The collars send out radio signals that tell people where the dogs are. No two wild dogs have the same pattern of coats, so it is easy to tell them apart. 课后课时作业（三） 149 篇章导读：本文是一篇说明文。文章主要介绍了非洲野狗的特征、生活习性及现状。 African wild dogs are smart and sociable, like pet dogs. Adult dogs, male and female, are willing to take good care of young ones. Millions of domestic dogs live on the planet, but there are probably fewer than 6，000 African wild dogs left. Humans hunt them and farmers who don't want them to go after cows and sheep poison them. Humans are also destroying the wild, natural habitat (栖息地) they need to survive in. Fortunately, today more farmers are finding other ways to protect their cows and sheep from African wild dogs instead of killing the animals. 课后课时作业（三） 150 12．Which of the following can explain why African wild dogs are different from domestic dogs? A．African dogs can live longer than domestic dogs. B．African dogs have fewer toes than domestic dogs. C．African dogs are much bigger in size than domestic dogs. D．African dogs are much more dangerous than domestic dogs. 解析：细节理解题。根据第一段第三句可知，非洲野狗只有四个脚趾，而家养的狗和狼有五个脚趾。故选B。 课后课时作业（三） 151 13．In Dr McNutt's view, African wild dogs ________． A．are a kind of wolves B．can be trained as pet dogs C．actually are missing domestic dogs D．generally are not used to living in groups 解析：细节理解题。根据第二段第一、二句可知，Dr McNutt认为，非洲野狗不是那些跑了却没有回来的家养狗，尽管有些人过去常常这么想。它们实际上是非洲的狼……由此可知，在Dr McNutt看来，非洲野狗就是一种非洲的狼。故选A。 课后课时作业（三） 152 14．What suggestion does the author give in the last paragraph? A．Farmers should use domestic dogs to fight against wild dogs. B．African wild dogs should be protected instead of being killed. C．Farmers should take responsibility for feeding African wild dogs. D．African wild dogs should be used to protect farmers' cows and sheep. 解析：推理判断题。根据最后一段最后一句可知，幸运的是，今天更多的农民正在寻找其他方法来保护他们的牛羊免受非洲野狗的伤害，而不是杀死这些动物。由此可推知，我们人类应保护这些数量并不多的非洲野狗。故选B。 课后课时作业（三） 153 15．Which of the following can be used as the title of the passage? A．How to Keep Wild Dogs B．How to Train Domestic Dogs C．An Introduction to African Wild Dogs D．Differences Between Domestic Dogs and Wild Dogs 解析：标题判断题。通读全文可知，本文主要介绍了非洲野狗的特征、生活习性及现状。因此C项(对非洲野狗的介绍)最适合作为文章标题。故选C。 课后课时作业（三） 154 课后课时作业（四） Ⅰ　阅读 When the sand began flying everywhere and hitting our faces, I started to worry that maybe we had made a mistake. That afternoon, my dad had stood on the deck (平台) of our home and laughed as our neighbors packed up and headed inland. They left to spend the night in motels or at friends' homes that were out of range of the approaching summer storm. 课后课时作业（四） 156 Challenging the weather that threatened to damp our spirits, we lit a fire on the beach. Dad told jokes and we had a good time. When it was 6：30 pm, all laughter disappeared. Our eyes were drawn to the sky. A tornado was headed straight for us! In a flash, we were all on our feet. The wind started screaming and now we were running to the cottage. My mom stopped next to the front door. “Where can we go？” she shouted at my dad. Most cottages on this part of Lake Michigan had been built without basements. Ours was no exception. The huge windows and the cottage itself wouldn't offer safety from high winds. 课后课时作业（四） 157 篇章导读：本文是一篇记叙文。文章主要讲述了作者一家人在龙卷风中逃生的经历。 “Follow me！” my dad yelled. We crawled (爬) beneath the deck, pressing ourselves against the foundation of the cottage. Between the deck supports, we watched the approaching storm in silent terror. My dad shouted, “Hold on！” and something else I couldn't hear over the screaming wind. I think he was praying. By the time it reached our cottage, it was nothing more than a strong wind. The rest of the storm lasted for an hour and then simply blew away. “Next time, we'll stay inland at Grandma's. Okay？” my dad said. 课后课时作业（四） 158 1．What did the family do before the storm came? A．They left the motels. B．They packed up the cars. C．They stayed on the beach.

It was my first time to go ice skating, so I was nervous. I was wondering how to skate. 课后课时作业（四） 179 I went with a friend who was very skillful. He spent some time teaching me how to skate, but I didn't learn much. He left me and skated all around. As soon as he left, I fell down. I envied the other people because they could skate very well. I was bored because I kept falling so I took off my skates and just walked around on the ice in my shoes. It was cold and my hands were frozen. Suddenly, I stepped on something that was not hard. What was it? It was a weak place in the ice. When I stepped there, I sank under the ice. I thought that I was going to die, but I did my best to grab something to get out from under the ice. I tried to grab the edge of the ice, but it was very difficult for an eleven－year－old boy. 课后课时作业（四） 180 It seemed like a very long time, like a year. Then, fortunately, someone helped me. He grabbed my arms and pulled me up. So, I lived and I'm still alive today. I thanked him. At that time, my friend came back. I was annoyed at him because he was supposed to take care of me, but he didn't. He was embarrassed. When I took a taxi home, the taxi driver was surprised and asked what had happened. I didn't want to say anything because I was tired and scared. Even now, whenever I think about that time, I feel uncomfortable. 注意： 1．续写词数应为150个左右； 2．请按如下格式在相应位置作答。 课后课时作业（四） 181 It was long before I went skating once again，﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ However, ever since then I haven't found any time to go skating, ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ 课后课时作业（四） 182 写前导读：本文是一篇记叙文。文章主要描写作者第一次滑冰时不慎踩到薄冰落入水中，一位好心人将他救起。这次经历让他又累又怕，很久之后再次滑冰作者又会经历什么？这两次经历让作者明白了什么？ 课后课时作业（四） 183 [精彩范文] It was long before I went skating once again, accompanied by one of my friends. This time I was careful and cautious, and my friend took special care of me. I was so fortunate this time that I did not fall down. Gradually I learnt to skate well and became skillful. I felt very confident and no longer scared. However, ever since then I haven't found any time to go skating, not because I do not like skating, but because I am too busy working. I've learnt a lot from these two skating experiences. We all have moments of desperation. But if we can face them bravely, we will find out how strong we really are. Whatever you do, you must have the patience to do it as well as the skill. Remember: Never get conceited because of victory or lose heart in case of failure. 课后课时作业（四） 184 R $
