Animals may also bee 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，eggsand 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 bee extinct without anyone knowing.【词海拾贝】1extinction n灭绝；绝种2steadily adv.平稳地3continuous adj.连续不停的；不间断的 4habitat v栖息地5destruction n破坏【问题思考】阅读短文，判断正(T)误(F)。1Before man arrived on Earth，species were not extinct.()2Scientists are quite sure why the dinosaurs became extinct.()3The increase in the human population causes the increase in the rate of extinction over the same period of time.()答案：1.F2.F3.T.将单词与其正确释义配对1decreaseA鉴赏；感激；意识到2reserve B安全的；可靠的3hunt C雇佣；利用4respond D减少；变小5contain E包含；容纳；容忍6affect F保护区7appreciate G成功；接替；继任8succeed H回答；响应；做出反应9secure I损害；危害10ine J收入11employ K打猎；猎取；搜寻12harm L影响；感动；侵袭答案：1.D2.F3.K4.H5.E6.L7.A8.G9B10.J11.C12.I.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.mercy2.bite3.inspect4.incident5.fierce.根据英语释义写出单词1_： far away in space or time2_： feeling of fort when something worrying has ended or not happened3_： to keep someone or something safe from harm4_： be able to control events5_： be important答案：1.distant2.relief3.protect4.powerful5.importance.选用短语的适当形式完成句子decrease to;

Yes, we may only do a little bit, but together our small actions add up to a lot.1Protect wildlife habitatPerhaps 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 munities 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.2Reduce the threat of invasive (入侵的) speciesThe spread of nonnative species has greatly reduced native populations around the world. Invasive species pete with native species for resources (资源) and habitat. They can even prey_on native species directly, forcing native species towards extinction.3Place decals (贴花纸) on windowsIt 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.4Slow down when drivingMany native animals have to live in developed areas and this means they must move in humanliving areas. One of the biggest obstacles (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。1What would be the best title for this passage?AHow animals go to extinctionBThe importance of protecting wildlifeCWhat to do to help save wildlifeDHow 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：C2People are advised to put decals on windows to_Adecorate the houses and beautify the environmentBprotect the windows from birds hittingCattract more birds to make homes nearbyDavoid 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：D3The underlined phrase “prey on” in the passage means_.Adrive awayBlive withCkill for food Dfight 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：C4We can learn from the passage that_Athe habitats of many species have been destroyedBabout one million birds are attacked by invasive species each yearCperhaps the biggest threat to many species is that they are easily bumped by carsDinvasive species only pete 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.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。_1_Home can be a great place for children to study.Its important to provide a workspace of their own where they can read books or just write a letter to their friends.Location(位置)2_Kitchens and dining rooms are not so well suited for regular study，since books and pens get in the way of the daytoday use of those areas.Set up a place where a child can settle in and leave papers and pens at hand without having to clear everything away each night.For a child that likes being alone，set aside a corner of his bedroom，but keep it separate from things like games，music and other hobbies not related to studying.Keeping things in orderParents should encourage their child to spread out，but to leave it neat and orderly when he isnt using his workspace.Ownership is very important for selfrespect._3_The workplace should be personal，but not another part of the playroom._4_Encourage the whole family to help build a supportive environment that children need for success in school.Give them a good example of how to deal with problems，how to manage time and get things done in the right way._5_Study will be more enjoyable and effective when supported by the whole family.AAttitude is everythingBBring organization into your homeCHere are several ways to choose a location.DBuilding a good home learning environmentEHold a cando attitude and your child will follow your example.FSetting up a space in a mon area of your home can be a good idea for children.GA child who learns to organize his space will carry organization into every corner of his life.答案：1.D2.F3.G4.A5.E.完形填空阅读下面短文，从短文后各题所给的四个选项(A、B、C和D)中，选出可以填入空白处的最佳选项。We find different kinds of animals in the world.Some animals such as tigers and lions，live in big _1_ and they are called _2_ animals.Some others like sheep and dogs are kept by men and they are called domestic(家养的)animals._3_ these animals are very different from each other，but we can _4_ them into two big groups：those that eat other animals and those that eat grass and leaves.Animals like tigers belong to the first group.Animals like cows，elephants and horses belong to the second group.Animals are of great _5_ to human beings.Men _6_ wild animals for their fur and meat.Domestic animals are even more important to men.Without them life will be very _7_People make use of animals in many ways.Cows and_8_are useful to mens _9_.They give 80% of the _10_ men eat every
