A
At the beginning of the 20th century there were more than a million lions worldwide. Today there are less than 30, 000 in the wild. The remaining lions are increasingly threatened by habitat loss, hunting and activities to protect farms and cattle.
For generations, Masai tribesmen on the large African plains in southeastern Kenya have hunted lions—to protect their farms and cattle. Today they celebrate the lions’ life.
Noah is an elder in the Masai community. “We have decided as a community of the Masai to lay down our spears, and there will be no more killing of lions in our community. ”
Conservation International’s Frank Hawkins explains, “The Masai have been living with wildlife for many generations and it has been a conflicting relationship in many ways. They compete with the animals for food as lions eat their cattle. We’re trying to find ways in which the wildlife will become something useful to them. ”They had the Predator Compensation Fund founded in 2003. After much discussion, a group of Masai farmers agreed to protect lions. In turn, if lions or other predators kill their cattle, the Masai owners will be paid market value for the dead animals from the fund.
One man said that in the past, when a lion killed cattle, they killed it on the spot. And now, after the start of the program, the Masai see the lion population growing. Since 2003, only four lions have been killed here, but up to now, the number of the lions hasn’t increased quickly.
1. What is this passage mainly about?
A. The wildlife in the world.
B. Lions and the Masai.
C. The reason why lions are killed.
D. The living ways of the Masai.
2. What is the aim of the Predator Compensation Program?
A. To protect people in the wild.
B. To help the Masai protect their farms and cattle.
C. To protect lions only.
D. To protect the wildlife.
3. Masai tribesmen killed lions before 2003 .
A. because lions were dangerous for people there
B. because dead lions were worth a lot of money
C. because they wanted lions’ meat
D. because they wanted to protect their farms and cattle
4. According to the passage, why haven’t Masai tribesmen killed any lions since 2003?
A. Because lions don’t eat their cattle any more.
B. Because they will be fined if they kill lions there.
C. Because if a lion kills their cattle, they will be paid for the dead animals from the fund.
D. Because there are less than 30, 000 lions in the wild now.
5. What do you think of the Masai?
A. Reasonable. B. Cruel.
C. Poor. D. Stupid.

Animal Conservation
Many animal and plant species have become extinct and many more are in critical danger. Finding ways to protect the earth’s wildlife and conserve the natural world they inhabit(居住)is now more important than ever.
The Dodo
The Dodo is a classic example of how human caused damage to the earth’s biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and the last one was killed in 1681.
Rhinos
The Rhino(犀牛)horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves. Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers.
The Giant Panda
The future of the WWF’s symbol is far from certain. As few as 1, 000 remain in the wild. The Chinese government has set up 33 panda reserves to protect these beautiful animals. However, the panda’s distinct black and white patched coat fetches a high price on the black market and determined poachers still pose(造成)one of the most serious threats to the animals.
Whales
Despite the fact that one-third of the world’s oceans have been declared whale sanctuaries(保护区), 7 out of 13 whale species remain endangered. Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions(碰撞)with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.
Tigers
The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5, 000 and 7, 000 and the Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.
6. It implies that .
A. the Dodo lacked the ability to protect itself from other animals
B. sailors to the Island of Mauritius lived mainly on the Dodo
C. the Dodo used to be a strong animal that liked fighting
D. the Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius
7. Which group of the following animals has already ceased to exist according to the text?
A. The Dodo, Rhino and Giant Panda.
B. The Rhino, Whale and South China Tiger.
C. The Rhino, Panda, Whale and Tiger.
D. The Dodo and the Bali, Javan, and Caspian tigers.
8. can serve as a cure for certain diseases.
A. The whale’s rich oil
B. The panda’s black and white patched coat
C. The Rhino horn and tigers’ bones and organs[来源:Z|xx|k.Com]
D. The Dodo’s delicious meat
9. Which of the following statements is NOT true?
A. The number of South China tigers has reached crisis point.
B. Many animals are threatened with extinction as a result of human activity.
C. People hunt for the endangered animals for high profit.
D. The whale is the representing mark for the WWF.
10. Which of the following is mentioned in all the descriptions of those wild animals?
A. The way of their life.
B. The reason for their extinction or being in danger.
C. Why they are hunted.
D. Punishment for hunting wild animals.
【拓展题型训练】根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
A. Join learning communities and help each other.
B. Expect problems, never be disappointed, and gradually you’ll make it.
C. Anytime is learning time.
D. Get interested and arouse your desire for knowledge.
E. Cover the same ground from different angles.
F. Try to be a good and effective learner.
As students, how we can learn our lessons effectively is a common problem which is always puzzling us. If you follow suggestions below, I’m sure you’ll find the solution easily.
1.
Your interest in the subject is the essential drive of success. You can’t learn what you do not want to learn. Emotion is an important part of the learning process. If you are even moderately interested in a subject, give yourself a chance. The key is to get started. If you can create some pleasurable routines, you may find that the subject grows on you. You must always remember learning is just like eating. You don’t expect to enjoy your food without appetite. Therefore, you should always try to arouse your interest and desire for knowledge if you want to learn well.
2.
Don’t expect to understand things, or remember too much the first time you study them. Think about what problem you will meet with in your study, so that you are well-prepared for it. Never be disappointed no matter what happens. Trust that things will get clearer as your brain comes to grip(理解)with new information. It is like a jig-saw puzzle or a cross-word puzzle. As you start to put the pieces together, or string the words together, the full picture becomes clearer. The brain learns all the time, but on its own schedule. Learning does not take place according to a schedule laid down by a curriculum or teacher. Keep at it, and you will gradually find that things that seem difficult at first will become second nature with time.
3.
Your brain is struggling to form patterns to cope with new input from your learning activities. Sometimes, no matter how long you focus on one subject, your brain is not going to pick it up. If you are stuck, move on. Then cover the same general information from a different source, a different book, or a blog, or an online lecture or a video. Try to become a grazing learner, wandering about the countryside, rather than a feed-lot learner, just standing there in one spot, chewing the same bale of hay. The broader your base, the easier it is to learn. Just as the“rich get richer”, the more you know, the more you can learn.
4.
Take full advantage of the Internet, blogs, and various mobile devices, not to mention good old-fashioned books and magazines. Learn during “dead time”. Listen in your car, on the train, or while jogging. Have your learning with you while waiting in the doctor’s office, or listen while checking out at the supermarket. Anytime is learning time. Remember, you are learning through exposure, not by nailing things down. It is more like moisture accumulation in a cloud, rather than building a brick wall.
5.
The “loneliness of the distance learner” is a thing of the past. Join a learning community on the web, where members share their knowledge and experience. Search for the communities that suit your interests and learning styles. You will find encouragement, advice and stimulus from fellow learners, as well as from tutors, teachers and coaches. In these communities, you can measure your progress against your own goals, or compare your experience with that of other learners. You can even teach and help others, which is a great way to learn.
答案与解析
一、完形填空。
【文章大意】本文通过讲述美国阿拉斯加州起初因为人们的滥捕滥杀, 导致狼这种动物几乎濒临灭绝, 后来政府通过立法对狼进行了保护, 但不久狼又泛滥成灾这一事例, 说明了保持生态平衡的重要性。全文还讲了生态平衡遭到破坏后, 狼的数量的增加给狼及当地人们所带来的损害。
1. C 【解析】逻辑推理题。过去人们大量捕杀狼, 然而后来国家通过法律保护狼, 因此前后为转折关系。But也可表示转折, 但but是连词, 不用逗号分开。
2. B 【解析】前后照应题。此空从前文because hunters were killing hundreds of them for sports得出。
3. D 【解析】背景常识题。有的人捕杀狼是为了它们的皮。
4. A 【解析】逻辑推理题。因为有法律保护狼, 因此狼的数量增加了。
5. D 【解析】习语搭配题。从空后的their own food 看, 本空应该填“毁灭”。
6. A 【解析】背景常识题。狼太多了, 它们破坏了自己的食物供应。
7. B 【解析】词汇复现题。下文中的People there also hunt deer. . . 等一系列关于鹿的叙述为重要提示。
8. C 【解析】词汇复现题。文章一直在探讨食物链的问题, 上下文中几处有“food”这一重要线索。
9. B 【解析】词语辨析题。在此A有较大干扰性, 作者说寒冷的冬季及食物的变化对鹿伤害极大, 但还不至于死亡。下一句“当鹿找不到食物时, 它们就会死亡”也能说明这一点。
10. D 【解析】气候的寒冷和植物的变化……。
11. C 【解析】逻辑推理题。鹿找不到足够的食物便会死亡。
12. B 【解析】逻辑推理题。如果狼继续杀死大量的鹿, 鹿总有一天会灭绝, 狼也会。
13. A 【解析】逻辑推理题。从空后的some day看, 作者在讲述未来的结果, 联系空前的内容, 鹿有一天会灭绝。
14. C 【解析】逻辑推理题。基于上面的原因, 我们应该改变这样的食物圈。
15. A 【解析】词语辨析题。在此B有较大干扰性, keep. . . from意思是“阻止……做某事”, 而save. . . from意思是“从……中把……挽救出来”。
16. D 【解析】逻辑推理题。从下文我们得知, 如果狼得不到足够的鹿, 它们就会去袭击鸡等, 因此保护好鹿, 也会使some farm animals得到保护。
17. D 【解析】逻辑推理题。hare的意思是“野兔”, 它不是农场的动物, 因此B不合题意; 在C、D项中, cows是较容易捕杀的, 因此D为最佳答案。
18. C 【解析】词语辨析题。want the United States government to do符合句意。A、D显然不合题意, insist形成的搭配为insist on doing, 而不可以是insist sb. to do sth. 。
19. A 【解析】逻辑推理题。从空后的to study the problem可知答案。
20. B 【解析】逻辑推理题。他们认为在有的地区捕杀狼而在数量少的地方保护狼是有必要的。
二、阅读理解。
A
【文章大意】马赛人有保护牛而射杀狮子的历史, 在“捕食性动物补偿计划”实施后他们开始保护这些野生动物。
1. 【解析】选B。主旨大意题。通读全文可知, 因为狮子经常吃掉马赛人的牲口, 所以马赛人杀死狮子, 因而导致狮子的数量减少, 在“捕食性动物补偿计划”实施之后, 马赛人得到了补偿, 所以不再杀害狮子, 所以文章主要是关于马赛人与狮子之间的关系。
2. 【解析】选D。推理判断题。本文虽然主要谈论了“捕食性动物补偿计划”怎样保护狮子, 但该计划并不只是为了保护狮子。第四段中的We’re trying to find ways in which the wildlife will become something useful to them. 说明“捕食性动物补偿计划”是为了保护所有的野生动物。
3. 【解析】选D。细节理解题。由第二段. . . —to protect their farms and cattle. Today they celebrate the lions’ life. 可看出马赛人是为了保护他们的农场和牛才杀死狮子的; 而第四段中的They compete with the animals for food as lions eat their cattle. 是指马赛人与动物们争抢食物。动物们猎杀他们饲养的牛, 他们就杀死这些动物以此来减少损失, 这句并不是说马赛人猎杀狮子是为了吃它们的肉。
4. 【解析】选C。推理判断题。从最后一段第二句可知现在如果有狮子或别的食肉类动物杀死了他们的牛, 他们就可以从“捕食性动物补偿基金”里获得补偿, 所以他们没必要再杀狮子了。
5. 【解析】选A。细节理解题。从为了保护牲口不得已而杀狮子, 到得到补偿后同意保护狮子, 都显示了马赛人是很通情达理的。
B
【文章大意】本文主要介绍了五种野生动物及其(濒临)灭绝的原因。
6. 【解析】选A。推理判断题。从文章中的“flightless, easily controlled”等词可推测出嘟嘟鸟缺少保护自己的能力。
7. 【解析】选D。细节理解题。根据文章第二段的“The population of Dodos rapidly decreased and the last one was killed in 1681. ”一句可判断Dodo是灭绝的动物之一, 再根据最后一段中的“the Bali, Javan, and Caspian tigers are already extinct”一句可得出其他几种。
8. 【解析】选C。细节理解题。文章的第三段和最后一段提到“犀牛角和虎骨及器官”有很高的药用价值。
9. 【解析】选D。推理判断题。从第四段中的“The future of the WWF’s symbol is far from certain. ”一句可得出“世界自然保护基金组织”的图案标志是“大熊猫”, 而不是“鲸”。
10. 【解析】选B。文章结构题。针对五种野生动物介绍, 内容不尽相同, 有的介绍了人们为什么猎取它们; 有的介绍了这些野生动物剩余的数量; 有的介绍了对于猎取野生动物的惩罚手段, 但有一点是相同的, 即: 嘟嘟鸟灭绝的原因以及其他四种野生动物濒临灭绝的原因。
【拓展题型训练】
1~5. DBECA
1. D【解析】根据第一句：你对这个主题的兴趣是成功的基本驱动力。主要谈及对科目的兴趣，故应为D：Get interested and arouse your desire for knowledge..

SHANGHAI—The dolphins(海豚) of China's Yangtze River could die out in 20 years unless fast and effective measures are taken to protect them from environmental dangers, a news report on Friday quoted scientists as saying.
The number of the river dolphins, which are found mostly in the middle and lower reaches of the Yangtze has become smaller sharply since 1990, with fewer than 100 of them remaining.
The serious and difficult condition of the Yangtze dolphins was among the topics discussed at a conference this week in Shanghai.
In the 1950's, there were thousands of river dolphins in the Yangtze, China's longest river，but environmental pollution, overfishing, boat propellers(螺旋桨)and the buildings of dams and sluice(水闸)gates became a threat to them as well as other species, including bottle-nosed and white dolphins in China's rivers and the South China Sea.
The number of bottle-nosed dolphins in the Yangtze has reduced since 1992 to 700 from about 2,000 and the number of white dolphins in the South China Sea is only about 1,000, the newspaper said.
According to scientists, there are more than 40 species of dolphins and whales in Chinese waters. The Chinese government plans to build additional areas along the Yangtze for the threatened species.
1．Since 1992, the number of bottle-nosed dolphins has reduced about________.
A．700 B．1,000 C．1,300 D．2,00

五、阅读七选五。
根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
A major source of teens’ stress is school exams, and test anxiety is not uncommon. When you recognize your teen is under stress, how can parents help your teen stay calm before an exam?
Be involved. Parents need to be involved in their teen’s work. 1 What he looks for is your presence—to talk, to cry, or simply to sit with him quietly. Communicate openly with your teen. Encourage your teen to express his worries and fears, but don’t let him focus on those fears.
Help him get organized. 2 Together, you and your teen can work out a time-table in which he can study for what he knows will be on the test.
Provide a calm setting. Help your teen set up a quiet place to study and protect his privacy. Give him a nutritious diet. It’s important for your teen to eat a healthy, balanced diet during exam times to focus and do his best. 3 If this happens, encourage your teen to eat light meals or sandwiches. A healthy diet, rather than junk food, is best for reducing stress.
4 Persuade your teen to get some sleep and/or do something active when he needs a real break from studying. Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance his time so that he will feel comfortable taking time out from studying to spend time with friends or rest.
Show a positive attitude. 5 Your panic, anxiety and blame contribute to your teen’s pressure. Make your teen feel accepted and valued for his efforts. Most importantly, reassure your teen that things will be all right, no matter what the results are.
A. A parent’s attitude will dictate their teen’s emotions.
B. Exam stress can make some teens lose their appetite.
C. They will only make the situation worse.
D. Encourage your teen to relax.
E. The best thing is simply to listen.
F. Help your teen think about what he has to study and plan accordingly.
G. Your teen may also make negative comments about themselves.

三、单项选择。
1. C 【解析】句意：你的同学们在集中精力学习，而你却抽出时间搞你的业余爱好，这值得吗？worthwhile指“值得花时间、精力去做”，并常用于“It is worthwhile doing sth.”句式。
2. A 【解析】句意：专家们说我们应当更加严格地控制因特网，这样我们可以保护我们的孩子不受有害网站的影响。此句要用protect表示“保护”；prevent/keep sb. from doing sth.都表示“阻止某人做某事”；defend表示“保卫”。
3. A 【解析】句意：那个国家的军事政府决定镇压所有的政治反对力量。put down“镇压”；put off“推迟”；put on“穿上”；put up“支起；张贴”。
4. C 【解析】句意：几分钟内警察就到了现场。on the spot是固定搭配，意为“在现场”。
5. A 【解析】句意：她预定是在星期五到达。在这期间，我们干什么呢？此句中meanwhile表示“在……期间”；however“然而”；therefore“因此”；then“那么”。

10. A 【解析】句意：有些老师经常尖刻地批评学生，这使得教室的气氛非常沉闷。making the classroom atmosphere very dull是现在分词短语作结果状语，表示一种自然而然的结果；不定式作结果状语多表示出乎意料的结果，故不选C项。
四、完形填空。
1. B 【解析】上半句中列举了大量的生命体，故用endless表示“无穷无尽的”。
2. D 【解析】我们已经命名的物种有150多万，并推测还有大量的我们没有发现的物种。remain undiscovered“还没有被发现的”。
3. C 【解析】with结构在句中作状语，表示原因。
4. A 【解析】become extinct“成为濒临灭绝的”，extinct在此作形容词，意为“灭绝的”；extinctive“使消减的”。

6. B 【解析】no longer＝not any longer“不再”，侧重时间，符合句意。no more侧重数量。

8. A 【解析】at risk“有危险”，为固定搭配。
9. C 【解析】darken“(使)变黑”。文中此处指成群的候鸽使天空变成了黑色。
10. D 【解析】over time“随着时间的变化”。此处指随着时间变化，由于栖息地的破坏及打猎造成候鸽数量的减少。
11. A 【解析】由the last one可知，最后一只候鸽是独自死去的，故用副词alone修饰died。lonely“孤独的；寂寞的”，强调感彩；separately“个别地；分别地”；single“单一的；唯一的”。
12. B 【解析】由but可知，前后意义有转折，后半句指出现在由于人类活动导致动物灭绝加速，故前句讲的是自然因素导致动物灭绝。
13. D 【解析】lose“失去”，符合句意。fail“失败”；miss“想念；丢失”；deprive“剥夺”。
14. C 【解析】表示“通过一项法案”用pass，此处用其被动形式，故选passed。

17. C 【解析】由第二段倒数第二句中的“habitat destruction”可推知答案为C项。
