Unit 4　Wildlife protection ‎ ‎ ‎【导语】　专家指出：地球上的动植物物种正以前所未有的速度消失，而无论是它们栖息地的丧失、污染，还是全球变暖带来的间接影响，祸根都源于人类。‎ ‎ ‎ 北部白犀牛　　　小嘴狐猴 Extinction is for ever!‎ As almost everyone knows，to become extinct is to be gone for ever.Even before man's arrival on Earth，species became extinct quite naturally.Natural extinction happens when a species decreases in numbers gradually but steadily at the end of its evolutionary period on Earth.The length of this period depends on how well a species can get used to changes around it.This process of extinction can take a very long time—sometimes several million years—and the extinction of one species is immediately followed by the appearance of another in a continuous cycle.‎ The case of the dinosaurs is the most well－known example of natural extinction.They appeared on Earth about 200 million years ago and dominated （统治）both land and sea for almost 100 million years.It is not certain why the dinosaurs became extinct，but their disappearance was a natural one and new species of animals evol ved to replace them.‎ The rate of extinction has speeded up unnaturally over the last 400 years，rising sharply since 1990.This increase in the rate of extinction is directly related to the increase in the human population over the same period of time.The great number of humans has caused great damage to the planet，as wild habitats have been taken over，forcing animals and plants into smaller and smaller areas，until some of them have become extinct.We have also polluted some habitats ‎ with chemicals and waste，making them unfit for wildlife.These causes of extinction are known as indirect destruction. ‎ Animals may also become extinct through direct destruction.This includes the hunting and catching of animals.Man has always hunted and killed wildlife but when early humans lived more in harmony with nature，they killed animals for essential food and clothing.When firearms were invented，great destruction of species was possible.Animals have been，and still are，killed for meat，clothing，medicines，feathers，eggs—and sometimes just for amusement.Some species are still caught in the wild for the live pet trade，even though their numbers are decreasing.‎ The extinction of at least 500 species of animals has been caused by man.Today there are about 5，000 endangered animals and at least one species dies out every year.There are probably many more which become extinct without anyone knowing.‎ ‎【词海拾贝】‎ ‎1．extinction 　 n．灭绝；绝种 ‎2．steadily adv.平稳地 ‎3．continuous adj.连续不停的；不间断的 ‎ ‎4．habitat v．栖息地 ‎5．destruction n．破坏 ‎【问题思考】‎ 阅读短文，判断正(T)误(F)。‎ ‎1．Before man arrived on Earth，species were not extinct.(　　)‎ ‎2．Scientists are quite sure why the dinosaurs became extinct.(　　)‎ ‎3．The increase in the human population causes the increase in the rate of extinction over the same period of time.(　　)‎ 答案：1.F　2.F　3.T ‎ ‎ ‎ ‎ Ⅰ.将单词与其正确释义配对 ‎1．decrease　　　　 A．鉴赏；感激；意识到 ‎2．reserve B．安全的；可靠的 ‎3．hunt C．雇佣；利用 ‎4．respond D．减少；变小 ‎5．contain E．包含；容纳；容忍 ‎6．affect F．保护区 ‎7．appreciate G．成功；接替；继任 ‎8．succeed H．回答；响应；做出反应 ‎9．secure I．损害；危害 ‎10．income J．收入 ‎11．employ K．打猎；猎取；搜寻 ‎12．harm L．影响；感动；侵袭 答案：1.D　2.F　3.K　4.H　5.E　6.L　7.A　8.G　‎ ‎9．B　10.J　11.C　12.I Ⅱ.根据所给汉语提示写出单词 ‎1．________n．仁慈，宽恕；怜悯 ‎2．________v．咬；叮；刺痛 ‎3．________vt．检查；视察 ‎4．________n．事件；事变 ‎5．________adj．凶猛的；猛烈的 答案：1.mercy　2.bite　3.inspect　4.incident　5.fierce Ⅲ.根据英语释义写出单词 ‎1．________： far away in space or time ‎2．________： feeling of comfort when something worrying ‎ ‎ has ended or not happened ‎3．________： to keep someone or something safe from harm ‎4．________： be able to control events ‎5．________： be important 答案：1.distant　2.relief　3.protect　4.powerful　5.importance Ⅳ.选用短语的适当形式完成句子 decrease to;

As is often reported, too many Tibetan antelopes are being hunted and killed illegally for their fur. By selling the fur, the illegal hunters can make great profits. As a result, the number of the Tibetan antelopes is decreasing rapidly from about 1，000，000 in 1990 to less than 100，000 at present. ‎ Immediate measures must be taken to solve the present situation. First, the importance of protecting the Tibetan antelopes should be advertised through your association. Second, would you provide more money ‎ for the preservation of the antelopes? Last but not least, I suggest that some volunteers be sent there to help protect them.‎ These are my suggestions and I hope they could mean something for a better future of the Tibetan antelopes.‎ Looking forward to your reply.‎ Yours sincerely，‎ Li Hua ‎ [来源:学。科。网Z。X。X。K]‎ A级　基础过关 Ⅰ.语法填空 在句中空白处填上适当的内容(1个单词)或括号内单词的正确形式。‎ ‎1．He felt nervous with the whole class ________ (look) at him.‎ ‎2．You must understand ________ importan t it is for us to learn English well.‎ ‎3．It is very important to keep children ________ (safety) when we are away on holiday.‎ ‎4．The woman tried her best to protect the chimps in their ________ (nature) habitat.‎ ‎5．We take this chance to express our sincere ________ (appreciate) of your help.‎ ‎6．The little girl ________ (bite) badly by mosquitoes last night.‎ ‎7．After ________ while，I began to get bored with my job.‎ ‎8．The thieves dropped the things and ran away as ________ (quick) as they could.‎ ‎9．One of the ________ (amaze) things about life，for me，is that we have a choice in everything we do.‎ ‎10．The TV set ________ (repair) by a friend of my father's now.‎ 答案：1.looking　2.how　3.safe　4.natural　5.appreciation　6.was bitten　7.a　8.quickly　9.amazing　10.is being repaired Ⅱ.完成句子 ‎1．The park was full of freshness and beauty of spring，________________________________(阳光照耀，鸟儿歌唱)．‎ ‎2．________________________________(在学年远未结束之前)，students begin their search for job during vacation.‎ ‎3．Too much stress not only makes us lose our motivation to study______________________________(而且毁了我们的健康)．‎ ‎4．Everyone wants to visit the place ____________________(他曾工作过的)．‎ ‎5．If visitors to the place do _______________________(像那对夫妻一样)，it will be polluted soon.‎ ‎6．My uncle is ________________________________(如此和善以至于)all of us like him.‎ 答案：1.with the sun shining and birds singing　2.Long before the end of the school year　3.but also ruins our health　4.where he once worked　5.as the couple did　‎ ‎6．so kind that B级　能力提升 Ⅲ.阅读理解 阅读下面的短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。‎ ‎ ‎ Can we give a hand to those endangered animals? Yes, we may only do a little bit, but together our small actions add up to a lot.‎ ‎1．Protect wildlife habitat Perhaps the greatest threat that faces many species is the widespread destruction of habitat. Cutting down forests, farming, and development all result in loss of wildlife habitat. In areas where rare species live, habitat destruction can quickly force a species to extinction. By protecting habitat, entire communities of animals can be protected together naturally. Parks and reserves are now all too often the only habitats that are left untouched by habitat destruction.‎ ‎2．Reduce the threat of invasive (入侵的) species The spread of nonnative species has greatly reduced native populations around the world. Invasive species compete with native species for resources (资源) and habitat. They can even prey_on native species directly, forcing native species towards extinction.‎ ‎3．Place decals (贴花纸) on windows It is reported that as many as one million birds in the United States die each year because of collisions (碰撞) with windows. You can help reduce the number of collisions simply by placing decals on the windows in your home and office.‎ ‎4．Slow down when driving Many native animals have to live in developed areas and this means they must move in humanliving areas. One of the biggest obstac les (障碍) to them is that created by roads. Roads divide habitat and present a constant risk to any animal attempting to cross from one side to the other. So when you drive out, slow down and keep an eye out for wildlife.‎ ‎【语篇解读】　我们能为濒危动物做点什么？本文给出了很好的建议，我们每个人都可以为此伸出援手，尽自己的微薄之力。‎ ‎1．What would be the best title for this passage?‎ A．How animals go to extinction B．The importance of protecting wildlife C．What to do to help save wildlife D．How to protect wildlife habitat 解析：主旨大意题。本文主要列举了人们怎样伸出援手去救助濒危动物，故C项最能概括文章的大意，为最佳标题。‎ 答案：C ‎2．People are advised to put decals on windows to________．‎ A．decorate the houses and beautify the environment B．protect the windows from birds hitting C．attract more birds to make homes nearby D．avoid birds hitting the windows by mistake 解析：细节理解题。根据第三种措施的描述可知，在窗户上贴花纸是为了避免飞鸟因误撞而丧命，故选D。‎ 答案：D ‎3．The underlined phrase “prey on” in the passage means ‎________.‎ A．drive away　　　 B．live with C．kill for food D．fight with 解析：词义猜测题。根据上文的意思：入侵物种与当地的物种争夺资源和栖息地。再结合该句的意思“它们甚至直接prey on当地的物种，这样迫使当地的物种灭绝”可推知，该短语的意思为“猎食，捕食”，故选C。‎ 答案：C ‎4．We can learn from the passage that________．‎ A．the habitats of many species have been destroyed B．about one million birds are attacked by invasive species each year C．perhaps the biggest threat to many species is that they are easily bumped by cars D．invasive species only compete for food with native species 解析：细节理解题。大概有一百万只鸟是死于误撞窗户，而不是外来物种的袭击，故B项错误；很多物种的最大威胁是栖息地被破坏；故C项不对；入侵物种和本地物种竞争的不仅仅是食物，还有栖息地和资源，故D项错误，A项指出许多物种的栖息地被破坏了，符合文章大意。故选A。‎ 答案：A Ⅳ.七选五
