This means there are very few animals of that kind left on Earth. The animals could face extinction. 1 When a type of animal is extinct, it is gone forever. One problem for animals is that their living places are sometimes destroyed by humans. As human populations increase, more and more space is needed. Building houses for people to live in forces animals to leave their natural homes. Trees are cut down to make room for homes and businesses. Swamps (沼泽) are filled in so that neighborhoods can expand (扩展). The living places are destroyed. The animals have nowhere else to go. 2 Humans must stop the extinction of animals because of the loss of their living places. We have to learn more about animal populations when considering building things. Other choices may not be so convenient. 3 Better planning can make a difference. It is still possible to keep so many kinds of animals for future children to enjoy. Another major problem is overhunting by humans. 4 The governments of countries around the world must agree on laws about protecting animals. Some animals may have large enough populations so hunting will not put them in danger. Others must be protected. 5 Some organizations are working hard to create living places for them. Breeding (繁殖) programs are helping animal populations increase. We all have to know the problem and think before we act. The things we do can have an effect on more than just ourselves. A. This is a worldwide problem. B. Extinction is when all the animals of that kind die. C. However, they can be helpful to the lovely animals. D. It is important for animals to have enough food to eat. E. There is still hope for animals on the endangered species list. F. Without a living place, the number of animals begins to go down. B In the office of remote sensing (遥感) scientist Liu Shaochuang, there is a huge photograph of a camel he snapped a decade ago in Xinjiang. He crouched for hours by a pool of water in the Gobi Desert to capture the image. Since 2012, he has led a team in tracking and studying wild camels using satellite remote sensing technology. Unlike zoologists who focus on species, Liu has studied the interrelationship between endangered animals and their environment, which he believes will help develop better protection strategies in the face of climate change. His interest in wild camels began when his team tested a prototype (雏形) design of the lunar rover Yutu in the desert. Living in the harsh deserts in northwestern China and southwestern Mongolia, camels are listed as critically endangered animals. Experts estimate that the population of this species is currently less than 1, 000, of which around 650 are in China. “Ten years ago, the research depended only on human observation, which was very primitive (原始的), ” Liu says. Because camels are fully migratory (迁徙) and can travel over long distances, scientists used to learn their habits by studying hoof prints and droppings. It was hard to find one camel in the desert, let alone track it. But Liu thought his expertise in satellite navigation (导航) and remote sensing might come in useful in the study of wild camels. It was not easy at first. Liu learned zoology from scratch. His team had to spend several weeks each year braving dust and sandstorms in the vastness of the Gobi Desert seeking out camels. A scar on his right eyebrow is the result of a rollover accident on a rugged mountain road in Xinjiang. “The most exciting moment was attaching a satellite positioning collar to a wild camel.” The tracking collar, equipped with special receivers, weighs only a few hundred grams. It can detach automatically (自动分离) and will not have a negative impact on the daily lives of the animals. The locations of the tracked animals are transmitted via satellite every day. Based on the data, scientists can get to know their migratory paths, living environments and possible threats they may meet with. For Liu, it is worth the significant sci-tech effort to study such a rare species. He adds wildlife protection and research will become more precise and efficient with the help of technology. 1. What was it that made tracking wild camels difficult? A. The number of camels experienced a sharp decline. B. Massive migration made camels cover huge distances. C. Primitive tools were used in human observation. D. Hoof prints and droppings were never to be seen. 2. What can be inferred from the scar on his right eyebrow? A. His carelessness in carrying out his research. B. His inexperience at the very beginning of his work. C. The hard conditions under which he worked. D. The stress he met with in his work. 3. What does paragraph 7 mainly focus on? A. The formation of the tracking collar. B. The definition of the tracking collar. C. The importance of the tracking collar. D. The function of the tracking collar. 4. Which of the following can best describe Liu Shaochuang? A. Generous and ambitious. B. Confident and grateful. C. Creative and determined. D. Optimistic and modest. 1 / 9 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 5 Saving animals in danger Section 3 Grammar分层练习 基础达标 01 能力提升 02 拓展培优 03 一、基础夯实 1）It is adj. for/of to do sth. 它们的意思分别是___________________/______________________. 此结构中，如果表示人性格特征，品质的形容词用介词_____________. 如果表示事物属性的形容词介词用________________. 点对点练习 一、请将形容词分类 kind important nice polite clever lazy careful necessary difficult easy careless interesting foolish possible exiting impolite cruel stupid dangerous hard (1) 修饰sb. 与of 搭配的形容词有_________________________________________________________ _________________________________________________________.

This means there are very few animals of that kind left on Earth. The animals could face extinction. 1 When a type of animal is extinct, it is gone forever. One problem for animals is that their living places are sometimes destroyed by humans. As human populations increase, more and more space is needed. Building houses for people to live in forces animals to leave their natural homes. Trees are cut down to make room for homes and businesses. Swamps (沼泽) are filled in so that neighborhoods can expand (扩展). The living places are destroyed. The animals have nowhere else to go. 2 Humans must stop the extinction of animals because of the loss of their living places. We have to learn more about animal populations when considering building things. Other choices may not be so convenient. 3 Better planning can make a difference. It is still possible to keep so many kinds of animals for future children to enjoy. Another major problem is overhunting by humans. 4 The governments of countries around the world must agree on laws about protecting animals. Some animals may have large enough populations so hunting will not put them in danger. Others must be protected. 5 Some organizations are working hard to create living places for them. Breeding (繁殖) programs are helping animal populations increase. We all have to know the problem and think before we act. The things we do can have an effect on more than just ourselves. A. This is a worldwide problem. B. Extinction is when all the animals of that kind die. C. However, they can be helpful to the lovely animals. D. It is important for animals to have enough food to eat. E. There is still hope for animals on the endangered species list. F. Without a living place, the number of animals begins to go down. 【答案】1. B 2. F 3. C 4. A 5.

He crouched for hours by a pool of water in the Gobi Desert to capture the image. Since 2012, he has led a team in tracking and studying wild camels using satellite remote sensing technology. Unlike zoologists who focus on species, Liu has studied the interrelationship between endangered animals and their environment, which he believes will help develop better protection strategies in the face of climate change. His interest in wild camels began when his team tested a prototype (雏形) design of the lunar rover Yutu in the desert. Living in the harsh deserts in northwestern China and southwestern Mongolia, camels are listed as critically endangered animals. Experts estimate that the population of this species is currently less than 1, 000, of which around 650 are in China. “Ten years ago, the research depended only on human observation, which was very primitive (原始的), ” Liu says. Because camels are fully migratory (迁徙) and can travel over long distances, scientists used to learn their habits by studying hoof prints and droppings. It was hard to find one camel in the desert, let alone track it. But Liu thought his expertise in satellite navigation (导航) and remote sensing might come in useful in the study of wild camels. It was not easy at first. Liu learned zoology from scratch. His team had to spend several weeks each year braving dust and sandstorms in the vastness of the Gobi Desert seeking out camels. A scar on his right eyebrow is the result of a rollover accident on a rugged mountain road in Xinjiang. “The most exciting moment was attaching a satellite positioning collar to a wild camel.” The tracking collar, equipped with special receivers, weighs only a few hundred grams. It can detach automatically (自动分离) and will not have a negative impact on the daily lives of the animals. The locations of the tracked animals are transmitted via satellite every day. Based on the data, scientists can get to know their migratory paths, living environments and possible threats they may meet with. For Liu, it is worth the significant sci-tech effort to study such a rare species. He adds wildlife protection and research will become more precise and efficient with the help of technology. 1. What was it that made tracking wild camels difficult? A. The number of camels experienced a sharp decline. B. Massive migration made camels cover huge distances. C. Primitive tools were used in human observation. D. Hoof prints and droppings were never to be seen. 2. What can be inferred from the scar on his right eyebrow? A. His carelessness in carrying out his research. B. His inexperience at the very beginning of his work. C. The hard conditions under which he worked. D. The stress he met with in his work. 3. What does paragraph 7 mainly focus on? A. The formation of the tracking collar. B. The definition of the tracking collar. C. The importance of the tracking collar. D. The function of the tracking collar. 4. Which of the following can best describe Liu Shaochuang? A. Generous and ambitious. B. Confident and grateful. C. Creative and determined. D. Optimistic and modest. 【答案】1. B 2. C 3. D 4. C 【解析】本文主要介绍了遥感科学家刘少创通过卫星遥感技术追踪和研究野生骆驼，以了解濒危动物与环境的相互关系，并帮助制定更好的气候变化下的保护策略。 1. 细节理解题。根据“Because camels are fully migratory (迁徙) and can travel over long distances, scientists used to learn their habits by studying hoof prints and droppings. It was hard to find one camel in the desert, let alone track it.”可知，让追踪野生骆驼变得如此困难是因为大规模的迁徙使得骆驼要走很远的路。故选B。 2. 推理判断题。根据“His team had to spend several weeks each year braving dust and sandstorms in the vastness of the Gobi Desert seeking out camels. A scar on his right eyebrow is the result of a rollover accident on a rugged mountain road in Xinjiang.”可知，从他右眉上的伤疤可以推断出他工作的艰苦条件。故选C。 3. 主旨大意题。根据“The tracking collar, equipped with special receivers, weighs only a few hundred grams. It can detach automatically (自动分离) and will not have a negative impact on the daily lives of the animals. The locations of the tracked animals are transmitted via satellite every day.”可知，第七段重点讲的是跟踪项圈的功能。故选D。 4. 推理判断题。根据“In the office of remote sensing (遥感) scientist Liu Shaochuang, there is a huge photograph of a camel he snapped a decade ago in Xinjiang. He crouched for hours by a pool of water in the Gobi Desert to capture the image.Since 2012, he has led a team in tracking and studying wild camels using satellite remote sensing technology.”可推知，刘少创是有决心和创造力的。故选C。 1 / 9 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 5 Saving animals in danger Section 3 Grammar分层练习 二、选择for或of填空。 1.for 2.of 3.for 4.of 5.of 6.for 7.for 8.of 9.of 10.of 点对点练习 1-2 C A 3.old enough to too…to 4.so that 5.】old enough so that。 1-6 ABCCBA 三、用单词的适当形式填空 1.to say to do 2.eating 3.to touch 4.saying 5.healthily 6.bored 7.to make 8.endangered 9.organization 10.behavior 四、写出下列句子的同义句 1.too young to go 2.not big enough for 3.It is for 4.too old to 5.it stupid of to make 6.It is to 7.strong enough 8.so that couldn’t 9.too for me 10.so that 五、完成句子。 1.old enough 2.It is to finish 3.It is to protect 4.of her 5.too to 6.old enough not to 7.dangerous for 8.necessary for 9.important for 10.old enough to 11.tall enough to reach 12.not brave enough to 六、短文填词 A语法填空 1. be found 2. for 3. appearance 4. heavier 5. teeth 6. easily 7. unusual 8. before 9. called 10. or 七、 阅读配对 1.
