四、阅读理解

Snow leopards (豹) are so hard to photograph that scientists aren't even sure how many of these endangered animals still live in the wild.
The Snow Leopard Conservancy(SLC) set up 20 cameras in Russia in 2010 to learn more about the big cat. After a full six months, they had exactly zero picture! That's when the organization understood they needed help. And the only people who could help them in finding the leopards were the very people from whom they wanted to protect the animals—local hunters.
Hunting snow leopards is against the law in Russia, but in the terrible climate of Siberia, the few people living there had to turn to poaching (偷猎) to feed their families.
In 2013, Russian naturalist Sergei Spitsyn approached Mergen Markov, a local hunter, and told him his project. Markov agreed to set up the camera where he knew he would find leopards, and it worked.
Markov, once a poacher, works full time for the conservationists now and has 10 cameras monitoring leopards. "I visit each camera once a month. I have known this whole region since I was a child," he said proudly.
The World Wide Fund For Nature (WWF) began working with other local villagers in 2015. The village would be paid 40,000 rubles(卢布)at the end of the year if the image of a snow leopard is caught. The WWF also rents horses from the villagers so that they do not need to make money by poaching anymore. "Today there are far fewer leopard poachers but leopards still get caught in traps set for other animals, so I have to stay watchful," said Markov.
Changing guns for cameras has made a big difference in the lives of these former poachers, the village, and the Russian snow leopards. The number of snow leopards has been rising and their population is expected to recover to normal levels within 10 years.
41．Why was no picture of snow leopards taken in six months
A．Because the SLC's 20 cameras failed to work properly.
B．Because the number of snow leopards in the wild was too small.
C．Because the local poachers destroyed these cameras on purpose.
D．Because the researchers knew little about the animal's living habits.
42．What did Sergei Spitsyn persuade Markov to do
A．Find the poachers. B．Repair cameras in the forest.
C．Catch more leopards. D．Work for the SLC.
43．Why did the WWF begin working with local villagers
A．To get some pictures of snow leopards.
B．To help villagers make a living.
C．To prevent villagers from hunting animals.
D．To rent their horses at a low price.
44．How can we describe the WWF's cooperation with the villagers
A．Practice makes perfect.
B．Curiosity kills the cat.
C．Kill two birds with one stone.
D．Old habits die hard.
阅读理解
Many of the Earth's creatures die because of humans' choices. These choices have nothing to do with food or shelter or anything else that helps humans survive. What kills millions of animals all over the world is that humans want to make money by doing so.
People use parts of animals for everything from hats to handbags, from jewelry to ashtrays(烟灰缸) and to make powders that supposedly improve a person's life. Deciding that a species is endangered and protecting it by law are not always enough. People who kill wildlife illegally rarely get caught.
During the late 1980s, saving elephants became a popular cause. Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory. These groups also proved that certain populations of elephants were decreasing. As a result, most people stopped buying objects made of ivory. Laws against poaching (偷猎) were made stronger. Many countries made importing ivory illegal. Killing elephants for their ivory became more risky and less profitable.
However, concern for certain species will become weak after a while. In the late 1970s, people protested against the killing of seal babies. Everyone was shocked to see young seals being killed in their icy habitat. The cruel activity stopped. But ten years later, the number of killed seal babies was higher than ever.
Other animal protection movements have come and gone, such as saving the whales and protecting dolphins. The whale population appears to have increased for now. And the laws are finally changed in America to protect the dolphins that swim with tuna fish in parts of the Pacific Ocean.
In the years to come, people's attention will probably turn to some other endangered species. Plenty of them urgently need attention.During this time, will the elephants be forgotten
45．What leads to the disappearance of millions of wild animals
A．The growing human population.
B．Humans' hope of making a fortune.
C．Humans' too much need for wild food.
D．Not having enough laws on wildlife protection.
46．What can we infer from the text about what happened in the late 1980s
A．Wildlife protection groups did make great efforts.
B．Importing ivory in all countries was illegal.
C．Those who killed elephants all got caught.
D．Hunting was completely not allowed.
47．Why are seal babies mentioned in Paragraph 4
A．To show the effort to protect seal babies.
B．To show an increasing number of seal babies.
C．To show the decrease of worry about certain species.
D．To show people's protest against the killing of seal babies.
48．What does the author mean by using the underlined sentence
A．Humans should choose some rare animals to protect.
B．Attention must be paid to saving some endangered wildlife.
C．Success has been achieved in quite a few cases of wildlife protection.
D．Concern and movements for animal protection should be always kept.

29．句意：。但我知道，如果没有一些帮助，乔治将无法生存。A：go“去”；B：grow“种植，生长”；C：survive“存活”；D：swim “游泳”。根据空后“without some help”可推断，被遗弃且身体虚弱的小海豹在没有帮助的情况下，无法存活下来。故选C。

The Snow Leopard Conservancy(SLC) set up 20 cameras in Russia in 2010 to learn more about the big cat. After a full six months, they had exactly zero picture! That's when the organization understood they needed help. And the only people who could help them in finding the leopards were the very people from whom they wanted to protect the animals—local hunters.
Hunting snow leopards is against the law in Russia, but in the terrible climate of Siberia, the few people living there had to turn to poaching (偷猎) to feed their families.
In 2013, Russian naturalist Sergei Spitsyn approached Mergen Markov, a local hunter, and told him his project. Markov agreed to set up the camera where he knew he would find leopards, and it worked.
Markov, once a poacher, works full time for the conservationists now and has 10 cameras monitoring leopards. "I visit each camera once a month. I have known this whole region since I was a child," he said proudly.
The World Wide Fund For Nature (WWF) began working with other local villagers in 2015. The village would be paid 40,000 rubles(卢布)at the end of the year if the image of a snow leopard is caught. The WWF also rents horses from the villagers so that they do not need to make money by poaching anymore. "Today there are far fewer leopard poachers but leopards still get caught in traps set for other animals, so I have to stay watchful," said Markov.
Changing guns for cameras has made a big difference in the lives of these former poachers, the village, and the Russian snow leopards. The number of snow leopards has been rising and their population is expected to recover to normal levels within 10 years.
41．Why was no picture of snow leopards taken in six months
A．Because the SLC's 20 cameras failed to work properly.
B．Because the number of snow leopards in the wild was too small.
C．Because the local poachers destroyed these cameras on purpose.
D．Because the researchers knew little about the animal's living habits.
42．What did Sergei Spitsyn persuade Markov to do
A．Find the poachers. B．Repair cameras in the forest.
C．Catch more leopards. D．Work for the SLC.
43．Why did the WWF begin working with local villagers
A．To get some pictures of snow leopards.
B．To help villagers make a living.
C．To prevent villagers from hunting animals.
D．To rent their horses at a low price.
44．How can we describe the WWF's cooperation with the villagers

【解析】【分析】本文是一篇新闻报道，报道了雪豹管理局安装摄像头去拍摄雪豹的照片，获取有多少雪豹生存在野外，但没有拍到照片，于是他们找猎人帮助，猎人因此不再捕杀雪豹，雪豹的数量一直在增加。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇新闻报道，通读全文，理解文章大意，阅读题目后返回原文阅读并找出与题目相对应的内容，仔细核对，选择符合原文原意的答案，完成后再次阅读并检查。
41．考查推理判断。根据第一段"Snow leopards (豹) are so hard to photograph that scientists aren't even sure how many of these endangered animals still live in the wild." 雪豹如此难以拍摄，以至于科学家们甚至不确定这些濒危动物中的多少仍在野外生存。因为是濒危动物，说明数量非常少，很难被拍摄到，所以推断6个月内没有照片是因为数量太少了，故选B。
42．考查细节理解。根据第四段"In 2013, Russian naturalist Sergei Spitsyn approached Mergen Markov, a local hunter, and told him his project. Markov agreed to set up the camera where he knew he would find leopards, and it worked." 2013年，俄罗斯博物学家Sergei Spitsyn找到当地猎人 Mergen Markov，告诉他自己的项目。Markov同意在他知道能找到雪豹的地方安装摄像机，结果成功了；以及第五段中的 "Markov, once a poacher, works full time for the conservationists now and has 10 cameras monitoring leopards. " Markov曾经是一名偷猎者，现在全职为自然资源保护主义者工作，有10个摄像头监控着雪豹。可推知Sergei Spitsyn劝说 Markov是为了保护雪豹，所以说 Sergei Spitsyn 说服 Markov 为雪豹保护协会工作，故选D。
43．考查细节理解。根据倒数第二段中的"The World Wide Fund For Nature (WWF) began working with other local villagers in 2015. The village would be paid 40,000 rubles(卢布)at the end of the year if the image of a snow leopard is caught." 世界自然基金会开始与当地村民合作。如果获取到雪豹的图像，该村将在年底得到4万卢布的报酬。可知WWF同当地村民合作就是为了获取雪豹的图像，故选A。
44．考查推理判断。根据倒数第二段中的"The World Wide Fund For Nature (WWF) began working with other local villagers in 2015. The village would be paid 40,000 rubles(卢布)at the end of the year if the image of a snow leopard is caught. The WWF also rents horses from the villagers so that they do not need to make money by poaching anymore." 世界自然基金会开始与当地村民合作。如果获取到雪豹的图像，该村将在年底得到4万卢布的报酬。世界自然基金会还向村民出租马匹，这样他们就不需要再通过偷猎赚钱了。可见世界自然基金会和当地村民的合作既可以帮助基金会获取雪豹的图像，又可以帮助当地村民赚钱。因此"一石二鸟"可以用来描述他们的合作，故选C。

Many of the Earth's creatures die because of humans' choices. These choices have nothing to do with food or shelter or anything else that helps humans survive. What kills millions of animals all over the world is that humans want to make money by doing so.
People use parts of animals for everything from hats to handbags, from jewelry to ashtrays(烟灰缸) and to make powders that supposedly improve a person's life. Deciding that a species is endangered and protecting it by law are not always enough. People who kill wildlife illegally rarely get caught.
During the late 1980s, saving elephants became a popular cause. Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory. These groups also proved that certain populations of elephants were decreasing. As a result, most people stopped buying objects made of ivory. Laws against poaching (偷猎) were made stronger. Many countries made importing ivory illegal. Killing elephants for their ivory became more risky and less profitable.
However, concern for certain species will become weak after a while. In the late 1970s, people protested against the killing of seal babies. Everyone was shocked to see young seals being killed in their icy habitat. The cruel activity stopped. But ten years later, the number of killed seal babies was higher than ever.
Other animal protection movements have come and gone, such as saving the whales and protecting dolphins. The whale population appears to have increased for now. And the laws are finally changed in America to protect the dolphins that swim with tuna fish in parts of the Pacific Ocean.
In the years to come, people's attention will probably turn to some other endangered species. Plenty of them urgently need attention.During this time, will the elephants be forgotten
45．What leads to the disappearance of millions of wild animals
A．The growing human population.
B．Humans' hope of making a fortune.
C．Humans' too much need for wild food.
D．Not having enough laws on wildlife protection.
46．What can we infer from the text about what happened in the late 1980s
A．Wildlife protection groups did make great efforts.
B．Importing ivory in all countries was illegal.
C．Those who killed elephants all got caught.
D．Hunting was completely not allowed.
47．Why are seal babies mentioned in Paragraph 4
A．To show the effort to protect seal babies.
B．To show an increasing number of seal babies.
C．To show the decrease of worry about certain species.
D．To show people's protest against the killing of seal babies.
48．What does the author mean by using the underlined sentence
A．Humans should choose some rare animals to protect.
B．Attention must be paid to saving some endangered wildlife.
C．Success has been achieved in quite a few cases of wildlife protection.
D．Concern and movements for animal protection should be always kept.
【答案】45．B
46．A
47．C
48．D
【解析】【分析】本文是一篇说明文，人类猎杀动物获利，当野生动物保护组织让人们了解到野生动物被非法捕杀数量不断减少时，人们才行动起来抵制用野生动物制作的产品，法律更加严厉制裁偷猎者。但是人们对动物的保护运动和关注力一直在改变，作者希望对动物保护的关注和行动应该一直保持下去。
【点评】本题考点涉及细节理解和推理判断两个题型的考查，是一篇环保类阅读，首先要仔细阅读短文，掌握大意，然后结合具体的题目，再读短文，从中找出相关信息，就可以确定正确答案。
45．考查细节理解。根据第一段中的"What kills millions of animals all over the world is that humans want to make money by doing so."世界上数百万动物死亡的原因是人类想赚钱，可知，人类希望发财导致了数百万野生动物的消失，故选B。
46．考查推理判断。根据第三段中的"During the late 1980s, saving elephants became a popular cause. Wildlife protection groups made sure everyone saw pictures or films of elephants with their faces cut off for their ivory...As a result, most people stopped buying objects made of ivory. Laws against poaching (偷猎) were made stronger. Many countries made importing ivory illegal. Killing elephants for their Ivory became more risky and less profitable "有利可图的)." 20世纪80年代末，拯救大象成了一个流行的事业。野生动物保护组织确保每个人都看到大象的照片或电影：它们的脸被切掉以获取象牙……结果，大多数人不再购买象牙制品。禁止偷猎的法律变得更加严格。许多国家禁止进口象牙。为得到象牙而捕杀大象变得更危险，利润也更低。可知，在20世纪80年代末，野生动物保护组织确实做出了巨大努力。故选A。
47．考查细节理解。根据第四段中的"However, concern for certain species will become weak after a while." 然而，对某些物种的关注会在一段时间后减弱。可知，提到海豹宝宝，目的是表明对某些物种的担忧减少了。故选C。
48．考查推理判断。根据倒数第二段中的"Other animal protection movements have come and gone..."其他动物保护运动来了又去……；以及最后一段中的"In the years to come, people's attention will probably turn to some other endangered species."在未来的几年里，人们的关注力可能会转向其他一些濒危物种。可知，对动物的保护运动和关注力一直在改变，那么在人们关注其他濒危物种时，大象会被遗忘吗？可推断，作者说这句话的意思是，对动物保护的关注和行动应该一直保持下去。故选D。
