chemicals.Better management of chemicals could save millions of lives and billions of dollars.As estimated,143,000 chemicals are now produced.Yet the report says only a small number of these chemicals have been studied for their effects on human health and the environment.It says death and disability rates are high from the unsafe use of chemical products.Sylvie Lemmet,director of the United Nations Environment Programme,says poor management of chemicals has a high economic cost.For example,she says the cost is higher than the amount of overseas development aid,or ODA,for health care in sub-Saharan Africa.She says,“Look at the estimated cost of poisoning from pesticide in sub-Saharan Africa,only the injury and the loss of working time is estimated to be 6.3 billion USA dollars in 2009.This is higher than the total ODA that is going to the health sector in the same area.”The United Nations Environment Programme estimates that chemical sales worldwide will increase by around three percent a year until 2050.Chemical production is moving quickly from developed to developing countries.By 2020,chemical production is expected to increase by 40 percent in Africa and the Middle East and 33 percent in Latin America.One of its biggest concerns is pollution of rivers and lakes by pesticides and fertilizers.Other major concerns are heavy metal pollution from the production of cement and textiles,and dioxin pollution from mining.The UN report urges the chemical industry and governments to work together to develop safety policies.It says preventing harm costs less than fixing it.21.The purpose of Paragraph 3 is mainly to indicate that.A.the use of pesticide causes a great lossB.Africa needs more development aidC.chemicals have a high production costD.the estimated cost of poisoning from pesticide is inaccurate答案:A解析:推理判断题。根据第三段的内容可知,SylvieLemmet是在说杀虫剂中毒给人类的身体和经济带来巨大的损失。故选A项。22.Which of the following is NOT a source of danger according to the text?A.Pesticides. B.Fertilizers.C.Heavy metals.D.Minerals.答案:D解析:细节理解题。根据倒数第二段后两句的内容可知,A、B、C三项均是危害的来源,而D项文中没有提及。23.According to the text,what is the main reason for the risks from chemicals?A.Poor management of chemicals.B.Lack of research funds on chemicals.C.The mass production of cement and textiles.D.Contradictions between chemical producers and governments.答案:A解析:细节理解题。根据第一段中的“Bettermanagementofchemicals.”和第二段中的“SylvieLemmet,directoroftheUnitedNationsEnvironmentProgramme,sayspoormanagementofchemicalshasahigheconomiccost.”可知应选A项。24.What would be the best title for the text?A.The truth in Sylvie Lemmets commentsB.A UN warning about chemical dangersC.The unpredictable future of chemical industryD.Preventing is much better than fixing答案:B解析:主旨大意题。本文讲的是联合国环境规划署号召我们要采取行动来减少日益增加的化学产品给人类带来的危害。故B项做本文的标题最合适。BThe personal computer has overtaken the family dog as mans best friend,according to a study.Researchers found that just 6 percent of us believe that “most people rely more on their dog than they do on their PC”,while 67 percent think the opposite to be true.Even 38 percent of dog owners admit relying more on their PC than on their dog,although 36 percent disagreed.And 71 percent of 18 to 24-year-old dog owners said they relied more on their computer.Paul Allen,editor of ComputerActiveMagazine,which conducted the poll with the Royal Society For The Protection Of Cruelty to Animals,said,“These days you can even take your PC for a walk,provided you have a laptop or tablet.”“Its only a matter of time until the first PC that fetches your slippers.”Researchers questioned 2,000 British adults to find out about the change modern technology has brought to their home life.They found that male dog owners are almost twice as likely as female owners to rely on their computer than a canine companion.Mr.Allen said,“With broadband bringing them global news and newspaper sales falling,the family dog even misses out on the pleasure of taking the paper to his owner.”But its not all bad news for honest dogs.“The family PC has given dog owners access to a wealth of resources and information that can help with the long-term care that a dog needs,” Mr.Allen said.25.According to the statistic, rely more on their computers.A.dog owners aged from 18 to 24B.female dog ownersC.British adultsD.36% of the people答案:A解析:细节理解题。从文章第四段“And71percentof18to24-year-olddogownerssaidtheyreliedmoreontheircomputer.”可以知道,18岁至24岁的宠物狗主人中,有71%表示更依赖电脑。26.Which of the following is the advantage that computers have brought to dogs?A.They can go out for a walk with their owners.B.They can be better looked after.C.They wont have to take paper to their owners.D.They can get on well with their owners.答案:B解析:细节理解题。文章的最后一段向我们说明的是家庭电脑给宠物狗带来的好处就是有利于主人对宠物狗的照顾。27.The family dog even misses out on the pleasure of taking the paper to his owner because .A.people gradually lose their interest in newspapersB.family dogs dont want to do that any moreC.people dont want to read newspapersD.people prefer to computers for news and information答案:D解析:细节理解题。文章倒数第三段说的是随着家庭电脑的普及使用,人们上网就可以看全球新闻,导致报纸销售量下降,所以宠物狗也就减少了为主人叼报纸的乐趣了。28.The underlined word “provided” means in the passage.A.offeredB.supposedC.as long asD.even though答案:C解析:词义猜测题。provided相当于aslongas,意思是“只要”,表示条件。CHave you ever wished you could have a clone of yourself to do homework while you went out playing with your friends?Imagine if you could really do that,where would you start?Whatexactlyiscloning?Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!You might not believe it,but there are human clones among us right now.They werent made in a lab,though theyre identical twins,created naturally.Below,well see how natural identical twins relate to modern cloning technologies.Howiscloningdone?How does one go about making an exact genetic copy of an organism?There are a couple of ways to do this:artificial embryo twinning and somatic cell nuclear transfer.How do these processes differ?ArtificialembryotwinningArtificial embryo twinning is the relatively low-tech method of cloning.As the name suggests,this technology imitates the natural process of creating identical twins.Artificial embryo twinning uses the same approach,but it occurs in a dish instead of in the mothers body.SomaticcellnucleartransferSomatic cell nuclear transfer means using a different method from artificial embryo twinning,but it produces the same result:an exact clone,or a genetic copy of an individual.This was the method used to create Dolly the sheep.To make Dolly,researchers separated a somatic cell from an adult female sheep.Next,they transferred the nucleus from that cell to an egg cell from which the nucleus had been removed.After chemicals were used,the egg cell,with its new nucleus,developed into an embryo,which was implanted into a mother and carried to term.29.If an organism is cloned and a new organism appears,.A.the new organism doesnt look like the original oneB.every single bit of DNA is the same between the twoC.the new organism is slightly different from the original oneD.most bits of DNA are the same between the two答案:B解析:细节理解题。根据“ThismeansthateverysinglebitofDNAisthesamebetweenthetwo!”可知被克隆出的生物体与原生物体的DNA完全相同,没有一点不同。30.The approach of artificial embryo twinning .A.is the relatively high-tech method of cloningB.differs greatly from the natural process of creating identical twinsC.transfers the nucleus from a somatic cell to anotherD.is similar to the natural process of creating identical twins答案:D解析:细节理解题。根据“.thistechnologyimitatesthenaturalprocessofcreatingidenticaltwins.”知选D项。其余选项与原文意思不符。31.What is the main difference between artificial embryo twinning and natural identical twin?A.One is done in the dish;the other in the mothers body.B.One is done without the embryo but the other needs the embryo.C.One is done without the egg cell but the other needs the egg cell.D.Natural identical twin is easier than artificial embryo twinning.答案:A解析:细节理解题。根据“Artificialembryotwinningusesthesameapproach,butitoccursinadishinsteadofinthemothersbody.”可知选A项。32.The author writes the article mainly to .A.show the achievement of cloning researchB.show the importance of researching cloningC.tell readers some knowledge about cloningD.tell readers how cloning is done in the lab答案:C解析:主旨大意题。从对克隆方法与现象的介绍可知,作者是让读者了解一些克隆的知识。第二节(共5小题;每小题2分,满分10分)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。The person behind you constantly kicks the back of your seat.Your talkative seatmate doesnt understand your need for sleep.And the aircrafts bathroom is a total mess.These situations can make even a short flight unbearable.Hopefully you dont cause these unpleasant experiences for others.33._Always recline(向后倾斜)your seat slowly.Theres nothing worse than suddenly being hit in the knees by the seat in front of you.In addition,dont keep your seat reclined for the entire flight.Always keep it upright during mealtimes.And remember to put it in the upright position before going to the restroom(or anytime you leave your seat).34.
