7、能力提升练.阅读理解AWith rapid advances in medical science,cloning is slowly but surely looking like it could be in our near future.However,is it really an option that should be considered as a way to extend human life?Reproductive cloning may help human families gain children,but theres also a benefit for t

8、he animal world.It brings hope to people eager for children but unable to have their own or adopt.It can also bring about the recreation of species that have long since died,allowing scientists to fully study the species as a living creature instead of simply looking at images or bones.Many believe

9、that cloning can be used to replace failing organs.This will reduce the waiting list for organ donations and allow more people to be saved.Not only that,but because the organ is,in fact,your own organ,there would be less chance of rejection.Cloning could prove helpful in genetic research.Using cloni

10、ng technologies,genetic researchers would have a better understanding of the composition of genes and the effects of genetic constituents (成分) on human characters.Theres also the possibility of changing genetic constituents in cloned humans,and cloning could help fight genetic diseases.While the clo

11、ning of body organs can help extend human life,it could also cause a lot of malpractice (玩忽职守).Along with the ability to clone desired characters,there could be the possibility of people deliberately reproducing undesired characters.This could lead to a rise in malpractices within society.Cloning in

12、volves a process of creating identical genes.As such,there would be a lack of diversity in humankind.Scientists believe this lack of diversity will lower the human races ability to adapt.Whatever your view on cloning may be,studies show that the clone would in fact not be completely identical to the

13、 original just as twins are not completely identical.Though they might look alike,twins have different personalities and enjoy different things.The same could be said of clones.Even if technology were created in which your memories and thoughts could be transmitted (传送) to the clone,your clone would

14、 still be a different person.1.What good might reproductive cloning bring?A.It may help improve human well-being.B.It could contribute to the rising birthrate.C.It could help animals survive deadly diseases.D.It may enable scientists to better study extinct species.2.According to the text,cloning ca

16、 last paragraph?A.To stress twins similarities.B.To show twins are quite common.C.To carry out deeper research on twins.D.To better illustrate what a clone will be like.BWhen Barbra Streisand said that shed had her dog cloned for$50,000,many people learned for the first time that copying pets and ot

17、her animals was a real business.The story that gave people cause for concern,though,came out a few days later.It was about Monni Must,a Michigan photographer who paid to have Billy Bean cloned,a Labrador that had belonged to her oldest daughter,Miya.Miya died 10 years earlier.To Must,cloning the eld

18、erly dog was a way to keep her daughters memory alive.Alarm bells went off in my head.Must wasnt just cloning a pet.She was trying to preserve a lost child.It seemed awfully close to a real human cloning scenario,one in which a heartbroken parent tries to replace a son or daughter who dies early.I s

19、hot a question at Jose Cibelli,an animal cloning scientist at Michigan State University:Is it time to worry about human cloning again?Cibelli quickly emailed back:“Yes.”I met Cibelli 15 years ago,when I was among a group of journalists covering cloning nonstop.Back then,it seemed possible that someo

20、ne might try to copy a human being at any moment.There was an Italian doctor named Antinori who said he was trying.But human cloning never happened.The reason is clear.In many animals,only one in 100 cloned embryos ever leads to a live birth.Of those that are born,a few suffer from abnormalities (畸形

21、) and quickly die.Creating a human clone isnt only a question of technology.Youd also need a reason to do it,experts willing to help,and someone to fund it all.I finally asked Must if she would have Miya cloned if shed had the chance.She said its not a question she has an answer to.“When you have a

22、child who dies,you are not in a place to make a rational (理智的) decision,” she says.5.How did the author feel after knowing Musts story?A.He felt relieved.B.He was worried.C.He took pity on her.D.He secretly admired her.6.What do we know about human cloning 15 years ago?A.It received the publics atte

23、ntion.B.It was supported by Jose Cibelli.C.It was seldom covered by reporters.D.It was first tried by an Italian doctor.7.What does Paragraph 6 mainly focus on?A.Why cloned embryos are difficult to preserve.B.How the technology of cloning is developed.C.Why human cloning is challenging.D.How animals

24、 are cloned.8.What is Musts attitude toward cloning her dead daughter?A.She has no idea.B.She is uninterested.C.She thinks it is irrational.D.She is looking forward to it.七选五Future Football StarsFootball academies were set up by leading football clubs so their coaches could run trials to discover an

25、d train talented boys from as young as eight as potential players for their first team.This means that in Britain there are at least 9,000 boys at any one time attending academies after school who think they are going to be a famous footballer.1 One eight-year-old was selected for Chelsea Academy an

26、d he went from being top of his class at school to being the boy who was messing around at the back.His mother asked him why he wasnt trying hard at school any more.His reply was that he was going to be a footballer and be rich,so he didnt need to.In the end,he only lasted a year in the academy.2 An

27、d he wasnt so discouraged that he never played football again.3 Any sport where only a few can get to the top has many talented failures.These people are very good and do their best but finally it will not pay off because they are just not outstanding enough.In football,this effect is big because th

28、e number of players chosen by academies is so huge.4This doesnt put off all the boys who are spotted by the big football clubs and are desperate to join the academies.5 They get to play as much football as possible.The skills become part of them,as they are with professional players,so they are auto

29、matic and the boys dont have to think about them when theyre on the football field.A.Unfortunately,for most this isnt the case.B.The benefits are still there for them of course.C.All the big football clubs have a football academy.D.But,luckily for him,he was still young enough to get over it.E.But f

30、ootball is not alone when it comes to this kind of thing.F.Most of these wont get into a team and most wont become professionals.G.And footballers are much more likely to get injured when they play games.语法填空The dodo is the most famous of all the creatures 1.

31、emains of the dodo at Oxford are one of the greatest treasures of its museum.The dodo 2. (discover) by Europeans in 1507.It was a flightless bird 3. lived on the island of Mauritius in the Indian Ocean.Although the dodos were easy 4. (catch),their meat was not that tasty;their rapid decrease was pro

32、bably due less to hunting,and more to the fact 5. the dogs,cats,rats and pigs,6. (introduce) to Mauritius,destroyed the dodos eggs and habitat.By 1680 the bird was extinct.The dodos were a curiosity,and some were brought to Europe by 7. (wealth) collectors like John Tradescant.His 8. (collect) were

33、later brought to Oxford,where now only the dried head and foot remain.Although small in amount,these specimens (标本) represent the most complete remains of a single dodo,and are 9. great value to scientists today.DNA research has shown the dodo is 10. (close) related to pigeons and has finally solved

34、 the question of the dodos ancestors;without the Oxford specimens this would have been impossible.UNIT 9HUMAN BIOLOGYSection ATOPIC TALK & LESSON 1.1.clone2.camel3.goat4.clues5.treatment6.biology7.Mammals8.forever9.reproductive10.emotion.1.editor2.artificial3.twinsparison5.wholly6.to pass7.merely8.a

36、he species as a living creature instead of simply looking at images or bones.”可知,生殖性克隆使得再创造已经灭绝的物种成为可能,能够让科学家充分研究一个生物物种,而不是仅仅观察这些灭绝物种的图片和骨骼。故选D项。2.A细节理解题。由第三段中的“cloning can be used to replace failing organs”可知,克隆可以用于替换衰竭的器官,故可用于器官移植。3.C细节理解题。由倒数第三段中的“it could also cause a lot of malpractice”和“there

37、could be the possibility of people deliberately reproducing undesired characters.This could lead to a rise in malpractices within society”可知,克隆也会导致社会中的不端行为增加。4.D推理判断题。由最后一段中的“studies show that the clone would in fact not be completely identical to the original just as twins are not completely identi

38、cal.”可知,克隆体与母体并不是完全相同的;作者提到双胞胎是为了说明克隆体与母体的差别。【语篇导读】本文是议论文。文章讨论了克隆技术以及克隆人的问题。5.B推理判断题。根据第二段中的“The story that gave people cause for concern”及第三段中的“Alarm bells went off in my head.”和第四段中的“Is it time to worry about human cloning again”可知,Must克隆逝世女儿的宠物狗一事让作者感到非常担忧。6.A推理判断题。根据第五段中的“I met Cibelli 15 years

39、ago,when I was among a group of journalists covering cloning nonstop.copy a human being at any moment.”可推断,当时克隆人的想法受到了人们的广泛关注。7.C段落大意题。根据第六段中的“In many animals,only one in 100 cloned embryos ever leads to a live birth.and quickly die.”可知,克隆过程中能最后成活的个体极少。由此可见,该段主要介绍了克隆人类所面临的各种困难及挑战。8.A细节理解题。根据最后一段中的“S

40、he said its not a question she has an answer to.”可知,Must对是否会克隆自己女儿的问题并没有明确的答案。.【语篇导读】本文是说明文。许多孩子梦想着进入足球学院并成为明日之星,但是现实与梦想之间往往差距很大,能成为职业球员的只是凤毛麟角。1.A根据上文中的“This means that in Britain there are at least 9,000 boys.are going to be a famous footballer.”及下文中的“One eight-year-old was selected for Chelsea Ac

41、ademy.he only lasted a year in the academy.”可知,英国随时都会有至少9 000名男孩参加足球学院并梦想着最终成为一名明星球员,但是再根据8岁男孩未实现的足球梦可知,设空处应填“不幸的是,对于许多人来说,实际情况并非如此”。A项与上文构成转折关系。2.D根据上文中8岁男孩追求足球明星梦失败的例子及下文中的“And he wasnt so discouraged that he never played football again.”可知,8岁男孩虽然未完成足球梦,并落下了学业,但是他还年轻,还有重拾信心、继续奋战的机会。D项与上文构成转折关系,与下文

42、构成递进关系。3.E根据下文中的“Any sport where only a few can get to the top has many talented failures.”可知,许多运动也只有少数人能名列前茅,与此同时还会有许多落选者。由此可见,这种现象并不是足球领域所独有的。下一句的内容与E项构成递进关系。4.F根据上文中的“These people are very good and do their best.by academies is so huge.”可知,许多很有天赋的人最后并没有得偿所愿,因为他们还不够优秀,这种情况在足球中更普遍,因为被足球学院挑选的运动员人数众多

43、,所以绝大多数人最终没有成为专业队员并进入球队。F项符合此处语境。5.B根据下文中的“They get to play as much football as possible.when theyre on the football field.”可知,进入足球学院训练虽然不一定能成为足球明星,但也有很多好处。B项是对下文的总结。.【语篇导读】本文是说明文,介绍了灭绝了的渡渡鸟的相关情况。1.to have become考查不定式作定语。设空处作后置定语,且creatures与become之间是逻辑上的主谓关系,又因 become所表示的动作已完成,故填to have become。2.was

44、 discovered考查一般过去时的被动语态。由语境及in 1507可知,此处用一般过去时,又因the dodo与discover之间是被动关系,故填was discovered。3.that/which考查关系代词。设空处引导限制性定语从句修饰先行词bird,且在从句中作主语,故填that/which。4.to catch考查不定式作补语。be easy to do sth意为“做某事是容易的”。5.that考查连接词。设空处引导同位语从句,且从句意义和成分均完整,故填that。6.introduced考查过去分词作定语。introduce与“the dogs,cats,rats and pigs”之间是逻辑上的动宾关系,且introduce所表示的动作发生在过去,故填introduced。7.wealthy考查形容词作定语的用法。设空处作定语,意为“富有的”,故填wealthy。8.collections考查名词。设空处作主语,意为“收藏品”,由were可知用复数,故填collections。9.of考查介词。be of great value意为“有很大的价值”。10.closely考查副词。设空处修饰形容词related,故填closely。
