was founded in London in 1863.Professional players 18.________(admit)to the Football Association leagues in the mid­1880s.Sh ortly 19.________,the game became charged by professional teams.In

Federation International Association,has been played 25.________ four years since 1930.Ⅲ.阅读理解(共20小题;每一小题2分,总分为40分)AUp to now,some scientists have suggested that cloning existing people might be ethically(伦理地) acceptable in some cases.One possibility is generating replacement for a dying relative.All such possibilities,however,raise the concern that the clone would be treated as less than a complete individual,because he or she would likely suffer from limitations and expectations based on the family's knowledge of the genetic“twin〞.Those expectations might be false,because human personality is only partly determined by genes.The clone of an extrovert(性格外向的人) could have a quite different way of behavior.Clones of athletes,movie stars,or scientists might well choose different careers because of chance events in early life.Some people have also pointed out that couples in which one member is infertile (不生育) might choose to make a copy of one or the other partner.But society ought to be concerned that a couple might not treat naturally a child who is a copy of just one of them.Because other methods are available for the treatment of all known types of infertility,the traditional choice seems more appropriate.None of the suggested uses of cloning for making copies of existing people is ethically acceptable to my way of thinking,because they are not in the interests of the resulting child.It should go without saying that I am strongly opposed to allowing cloned human embryos to develop so that they can be tissue donors.In spite of this,it seems clear that cloning from cultured (人工培育的) cells will offer important medical opportunities.Predictions about new technologies are often wrong;societal attitudes change;unexpected developments occur.Time will tell.But biomedical researchers looking into the potential of cloning now have plenty to do.26.Towards cloning an existing person,what concern does the author show?A.The clone created is unlikely to fulfill your expectations.B.The clone created is ethically unacceptable.C.The clone created will be mistreated.D.The clone created will have one defect or another.27.From the text we know that a clone will________.A.be partly similar in personality to the person it is created fromB.share the same characteristics with the person it is created fromC.choose the same career as the person it is created fromD.behave in the same way as the person it is created from28.According to the passage,which of the following is right?A.One's personality is determined by neither their genes nor the environment they live in.B.One's personality is determined by both their genes and the environment they live in.C.One's personality is determined by their genes.D.One's personality is determined by the environment they live in.29.In the author's view,which of the following uses of cloning is reasonable?A.To help childless couples to have a baby.B.To culture cells for medical purpose.C.To develop tissue donors.D.To replace a lost relative.30.What is the author's attitude towards cloning technology?A.It should wait till people's views change.B.It should be condemned.C.It was unethical from the very beginning.D.It has medical potential for scientists to explore.BMy mom's entire life changed in the matter of a few seconds.While driving home late one night,my parents' SUV was hit from behind by a drunk driver traveling 70 miles per hour.Dad was killed instantly.Mom was thrown from the SUV and people found her on the side of the road.Once I saw my mom in the hospital,I knew she had a long road ahead of her.She had crushing injuries to her arm and shoulder,and her elbow was dislocated in three places,leaving it permanently bent.Although it took my mom a long time to physically recover from the accident,it was only a short time before my mom's positive spirit returned.Throughout her journey of recovery,my mother rarely complained.I could see the pain in her eyes during physical therapy,but never heard her question why this had happened to her.In fact,I remember one “role reversal〞 where we both just had to laugh.Mother had lost a lot of weight during her hospital stay,so I bought her some new clothes.Ihad to dress her at first,but she challenged herself every day.Finally,when she was able to get dressed on her own,she looked at me in the mirror and started laughing.While she appreciated the clothes I had bought,she really hated the styles I had chosen for her and couldn't wait to go shopping on her own.I started laughing too;she had struggled for months to put on these clothes that she didn't even like!It reminded me of when I was in kindergarten and my mother made me wear dresses when I just wanted to wear pants.It was a funny role reversal for both of us and I understood how she felt.It took my mom two long years to gain back her strength and limited flexibility.Those few years were a traumatic time for our entire family.Mom had to overcome many challenges.But she found that strength of will and a sense of humor can get you through the toughest times,even when you don't think you have anything to smile about.31.The author presented the story by ________.A.asking drivers to pay attention while drivingB.reminding readers not to drive too fastC.explaining the result of driving after drinkingD.describing the scene of the accident32.By saying “a long road ahead of her〞,the author meant ________.A.it would take her mother a long time to recoverB.her mother could continue to live for a long timeC.her mother needed to walk every day to get betterD.her mother would pay a lot for the treatment33.While recovering,her mother ________ .A.showed no pain during physical therapyB.kept her spirits up all the timeC.went into a deep depressionD.always asked why it happened to her34.The example of “role reversal〞 is used to prove ________.A.her mother was particular about dressingB.her mother behaved like a girl in the kindergartenC.her mother could keep a positive attitudeD.her mother had an eye for beautiful clothes35.The best title for the passage may be________.A.Remain Clam When Death Drawing NearB.Keep Your Head Up in Case of TroubleC.Show Real Courage in Front of DangerD.Persist No Matter What Your Troubles AreCColorado farmer Chris Jessen and his wife Pam became the newest owners of a “panda cow〞 when it was born on their farm on New Year's Eve.The calf(小牛),named Ben,was created through genetic engineering.Ben was the second panda cow born on Jessen's farm,but was a surprise,Jessen said that he was expecting a black calf.This rare breed of panda cow gets its nickname from its similarity to a panda bear.Its white face and black fur around its eyes are extremely panda­like.There is a white belt circle around the middle part of its black body.Baby Ben has a black mark on its forehead.Its thick newborn coat also increases the similarity to a panda.Ben is expected to grow four feet tall and weigh close to 1,000 pounds,like its father.The breed is not only extremely rare,but is also only ten years old.The first mini panda cow,Precious,was born on April 27,2000,on the Happy Mountain Miniature Cattle Farm,in Covington,Washington.It took 44 years of genetic engineering by Richard Gradwohl,although the farmer claims the new cow was actually an accident.Precious's father was an American Beltie bull,named Rebel.The mother was a small Happy Mountain cow,named Sarah.Gradwohl is the author of TheBeginnersGuidetoOwningYourOwnMiniatureCattleBusiness guidebook,a 24­part article series.These miniatures are actually kept to be pets.Jessen plans to sell Ben after training.Cows are social animals that respond well to humans and some will come when their names are called.Panda cows can be petted and are popular with many people.A close relationship can be formed with them,like other more traditional pets.36.Why was Ben a surprise to Chris Jessen?A.Because Ben looked different from what he had expected.B.Because Ben was born on New Year's Eve.C.Because Ben was created through genetic engineering.D.Because Ben was the second panda cow born on his farm.37.Why did the newborn get such a nickname?A.Because its newborn coat is soft and thick.B.Because it has a black mark on its forehead.C.Because it has a white face and black eyes.D.Because it looks like a panda in many ways.38.What can we learn from the last two paragraphs?A.Cows cannot understand humans' instructions very well.B.Ben will be kept as a pet by Jessen.C.Panda cows are too big to be petted.D.Gradwohl knows how to manage miniature cattle business well.39.Which of the following is a similarity between Precious and Ben?A.They were both created through genetic engineering.B.They are both four feet tall.C.They belong to the same owner.D.They were born in the same state of the USA.40.What is the main purpose of this passage?A.To introduce a new technology to us.B.To show us how the panda cow is made.C.To introduce a genetic engineering invention:the panda cow.D.To introduce the Happy Mountain Miniature Cattle Farm to us.D(2013·浙江高考)The baby monkey is much more developed at birth than the human baby.Almost from the moment it is born,the baby monkey can move around and hold tightly to its mother.During the first few days of its life the baby will approach and hold onto almost any large,warm,and soft object in its environment,particularly if that object also gives it milk.After a week or so,however,the baby monkey begins to avoid newcomers and focuses its attentions on “mother〞-the real mother or the mother­substitute(母亲替代物).During the first two weeks of its life warmth is perhaps the most important psychological(心理的) thing that a monkey mother has to give to its baby.The Harlows,a couple who are both psychologists,discovered this fact by offering baby monkeys a choice of two types of mothersubstitutes—one covered with cloth and one made of bare wire.If the two artificial mothers were both the same temperature,the little monkeys always preferred the cloth mother.However,if the wire model was heated,while the cloth model was cool,for the first two weeks after birth the baby monkeys picked the warm wire mother­substitutes as their favorites.Thereafter they s witched and spent most of their time on the more comfortable cloth mother.Why is cloth preferable to bare wire? Something that the Harlows called contact(接触) comfort seems to be the answer,and a most powerful influence it is.Baby monkeys spend much of their time rubbing against their mothers' skins,putting themselves in as close contact with the parent as they can.Whenever the young animal is frightened,disturbed,or annoyed,it typically rushes to its mother and rubs itself against her body.Wire doesn't “ru b〞 as well as does soft cloth.Prolonged (长时间的)“contact comfort〞with a cloth mother appears to give the babies confidence and is much more rewarding to them than is either warmth or milk.According to the Harlows,the basic quality of a baby's love for its mother is trust.If the baby is put into an unfamiliar playroom without its mother,the baby ignores the toys no matter how interesting they might be.It screams in terror and curls up into a furry little ball.If its cloth mother is now introduced into the playroom,the baby rushes to it and holds onto it for dear life.After a few minutes of contact comfort,it obviously begins to feel more secure.It then climbs down from the mother­substitute and begins to explore the toys,but often rushes back for a deep embrace(拥抱) as if to make sure that its mother is still there and that all is well.Bit by bit its fears of the new environment are gone and it spends more and more time playing with the toys and less and less time holding onto its “mother〞.41.Psychologically,what does the baby monkey desire most during the first two weeks of its life?A.Warmth. B.Milk.C.Contact. D.Trust.42.After the first two weeks of their life,baby monkeys prefer the cloth mother to the wire mother because the former is ________.A.larger in sizeB.closer to themC.less frightening and less disturbingD.more comfortable to rub against43.What does the baby monkey probably gain from prolonged “contact comfort〞?A.Attention. B.Softness.C.Confidence. D.Interest.44.It can be inferred that when the baby monkey feels secure,________. A.it frequently rushes back for a deep embrace when exploring the toys B.it spends more time screaming to get rewardsC.it is less attracted to the toys though they are interestingD.it cares less about whether its mother is still around45.The main purpose of the passage is to ________.A.give the reasons for the experimentB.present the findings of the experimentC.introduce the method of the experimentD.describe the process of the experimentⅣ.信息匹配(共5小题;每一小题2分,总分为10分)阅读如下应用文与相关信息,并按照要求匹配信息。

As she put it: "Who among us could tell a person suffering from cancer or Alzheimer's, 'you cannot have the cure that will save your life' ?" None of us, I am sure. So I hope after listening to all the arguments you too will be able to support medical cloning. Please vote for our side of the debate.

The arguments put by the team opposing medical cloning were less strong. They argued in two ways. Their first reason was that the procedures were not yet secure. Their second reason was that it took many tries and many potential(潜在的) animals to be killed to prarch.

Human cloning is the creation of a genetically identical copy of an existing or previously existing several highly public claims,human cloning still appears to be a is no solid scientific evidence that anyone has cloned human embryos at present.In 2023,a group in South Korea published a paper in the journal Science in which it claimed to have created a cloned human embryo in a test ,an independent scientific institute later found no proof to support the claim and,in January 2023,Science announced that the paper had been withdrawn.In January 2023,Dr Samuel Wood and Dr Andrew French in California announced that they successfully created the first 5 fully grown human embryos using DNA from adult skin cells,aiming to provide a source of viable embryonic stem Dr Wood stated that if that were possible,using the technology for reproductive cloning would be both immoral and 5 cloned embryos were destroyed.The various forms of human cloning are scientific,governmental and religious organizations oppose reproductive ,some people have considered the idea of growing organs separately from a human organism—in doing this,a new organ supply could be established without the moral

Perhaps they know parents who would like to buy a cloned baby. Perhaps this family is unable to have children of their own. So the laboratory keeps the real baby and sells the clones as they grow. WQ: But that’s a baby factory! That’s not moral at all!
5. Wang Qiao thinks it is moral to clone babies for parents who cannot have children.
Listen to the tape again and then choose the correct answers to the three questions on page 54.
cloning, Clare? CP: I don’t know what to think. But I
suppose it’ll come one of these days.
I think there are many problems that nobody has thought of yet. WQ: What do you mean by that? CP: Well, a clone will be an exact copy of the original donor. Right? WQ: Yes, so what? CP: Well, what’s the relationship between the clone and his original donor?

2014-2015学年高中英语 Unit 2 Cloning What is cloning素材 新

What is cloning?Cloning means the production of genetically identical animals. In 1995 scientists at the Roslin Institute in Edinburgh, Scotland produced Megan and Morag - two lambs cloned from a single embryo. In 1996 Dolly the sheep was produced, the first example of a clone produced not from an embryo cell but from a cell taken from an adult sheep. She was cloned using a nuclear transfer technique, where the nucl eus from a cell taken from the mammary gland of an adult sheep was fused with an un fertilized egg from which the nucleus had been removed. 277 cells were fused in this way, resulting in 29 viable embryos which were implanted into surrogate Blackface ewes. One gave birth to Dolly. Dolly died in 2003 after suffering the signs of p remature ageing such as arthritis and a liver complaint.The 'production' of Dolly has sparked a cloning frenzy. 1998 saw the arrival of cows cloned using the same technique that produced M egan and Morag 1. The Roslin institute cloned the first pig in 2000 2. In the US in 2001 a rhesus macaque monkey called Tetra was cl oned 3. Also in the US in 2002 a cloned kitten was reported 4 in the same year as the first cloned rabbits in France 5. In 2003 the first cloned mule 6, horse 7 and rat 8 were reported.Animal welfareCloning involves many possibilities for detrimental effects on animals. For example, cloned lambs and calves are frequently abnormally large at birth - some have been twice normal size. One cloning expert admitted in 1992 that "many cloned calves are abnormal".9 In Australia, a l amb of five times the mean birth weight for the breed has been recorded. In addition, cloned animals are often found to have malformed internal organs.10 Both of these adverse effects were seen in the first Edinburgh experiments in 1995 that led to Megan and Morag. In addition to death through malformed internal organs, one lamb had to be delivered by caesarean section because it had grown to twice its normal size in the womb, and all but one of the five cloned lambs were at least 20% larger than they should have been.Immediately after birth many cloned lambs have breathing difficulties, are lethargicand often will not suckle. As a consequence, perinatal mortality is high. Miscarriage rates are also high; this is thought to be at least in part because of 'large offspring syndrome'.11 C loning techniques also require a great deal of surgical intervention. Those sheep destined to be egg donors undergo hormone injections, followed by surgery to have the egg cells removed. Following nuclear transfer, it is common for the cloned embryos to b e surgically implanted into temporary recipient sheep. Six days later, these temporary 'foster mothers' are simply killed and the embryos removed. The embryos are then placed, again surgically, into the surrogate mother ewes. Some deliveries have been achieved via Caesarean section. So the process is far from simple, and the surgery required can reasonably be expected to inflict residual pain. Attempts to create clones of animals that have been already cloned could also result in increased suffering. In France 1999, a calf which was a clone of a clone died aged eight weeks of rapid depletion of blood cells and severe anaemia. The researchers concluded "…somatic cloning may be the cause of long-term deleterious effects".12One possible application of cloning, suggested by the Roslin team, is the facilitation of farm animal genetic engineering. If successful, the cloning technique could be used to 'mass produce' farm animals which had been genetically engineered to grow faster, bigger or leaner. Cloning could also be used to mass produce animals genetically engineered to produce pharmaceutical protei ns in their milk or blood (gene pharming), or for use in xenotransplantation. However, genetic engineering itself has a very poor track record in terms of animal welfare, and the BUAV is appalled at the idea of combining genetic engineering and cloning techniques. Former Archbishop John Habgood has written of the motives behind cloning experiments:"But should science be going down this road at all? What is the point of it? The simple answer is - money. The driving force behind most of the research in this field has come from the agricultural industry. I use the word industry deliberately. Cloning is a means of standardising products, and that is what industry always wants." 13It is clear that cloning may cause a great deal of animal suffering. The so-called 'benefits', such as the production of genetically identical herds or flocks of animals for intensive farming, may be seen as dubious or even highly unethical. T he BUAV therefore believes that the practice of cloning should be stopped immediately.希望对大家有所帮助,多谢您的浏览!。
