If parents bring up a child with the sole aim of turning the child into a genius, they will cause a big problem. According to several leading educational psychologists, this is one of the biggest mistakes which ambitious parents make. Generally, the child will be only too aware of what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children. However, if parents are not too unrealistic about what they expect their children to do, but are ambitious in a reasonable way, the child may succeed in doing very well—especially if the parents are very supportive of their child. Michael Lee Chao Tin is very lucky. He is crazy about music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometers a week for violin lessons. Although Michael’s mother knows very little about music, Michael’s father is a good trumpet player. However, he never makes Michael enter music competitions if he is unwilling. Michael’s friend, Winston Chiu Fang Weng, however, is not so lucky. Although both his parents are successful musicians, they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him for every piano competition held. They are very unhappy when he does not win. “When I was your age, I used to win every competition I entered,” Winston’s father tells him. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy.61.Which of the following mistakes are parents likely to make according to the passage?A.To neglect their child’s education.B.To help their child to be a genius.C.To expect too much of their child.D.To make their child become a musician.62.What should parents do in order to help their children succeed?A.They should push the children into achieving a lot.B.They should try to have their own successful careers.C.They should arrange private lessons for their children.D.They should understand and help their children in difficult times.63.Which of the following statements about Michael Lee’s parents is true?A.His father is a very poor player of trumpet.B.His parents are quite rich and have a car.C.His parents help him in a proper way.D.His mother knows much about music.64.Winston’s parents push their son so much that __________.A.he has succeeded in a lot of competitionsB.he is unhappy because he is not self-confidentC.he feels he cannot learn anything about music from themD.he has already become a better musician than his father65.The two examples illustrate the principle that __________.A.successful parents often have unsuccessful childrenB.it is important to let children develop in the way they wantC.parents who want their child to be musical should also be good musiciansD.the more money spent on a child’s education, the better the child will do

共用题干That scientists have cloned a sheep sends academics and the public into a panic at the prospect that humans might be next. That's an understandable reaction.(46)___________,so it's not unreasonable to be concerned that it might threaten human society and dignity.Yet much of the ethical oppo-- sition seems also to grow out of an unthinking disgust. And that makes it hard for even trained scientists and ethicists to see the matter clearly.While human cloning might not offer great benefits to humarnty,no one has yet made a persuasive case that it would do any real harm,either.(47)_______That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower stature.But why suppose that cloned persons wouldn't share the same rights and dignity as the rest of us?A leading ethicist has suggested that cloning would violate the "right to genetic identity".(48)________It makes perfect sense to say that adult persons have a right not to be cloned without their voluntary,informed consent. But if such consent is given,whose "right"to genetic identity would be violated?So who will likely take advantage of cloning?Perhaps a grieving couple whose child is dying. (49)________But a cloned child born to such dubious parents stands no greater or lesser chance of being loved,or rejected,or warped than a child normally conceived.Infertile couples are also likely to seek out cloning. That such couples have other options(in vitro fertilization or adoption)is not an argument for denying them the right to clone.Or consider an example raised by Judge Richard Posner:a couple in which the husband has some tragic genetic defect. Currently,if this couple wants a genetically related child,(50)________They can reproduce naturally and risk passing on the disease to the child.They can go to a sperm bank and take a chance on unknown genes.They can try in vitro fertilization and dispose of any afflicted embryo though that might be objectionable,too.Or they can get a male relative of the father to donate sperm,if such a relative exists.This is one case where even people unnerved by cloning might see it as not the worst option.Even if human cloning offers no obvious benefits to humanity,why ban it?In a democratic society we don't usually pass laws outlawing something before there is actual or probable evidence of harm.Most important,human cloning should be governed by the same laws that now protect human rights.A world not safe for cloned humans would be a world not safe for the rest of us._______（49）A:they have four not altogether pleasant options.B:This might seem psychologically twisted.C:Theologians contend that to clone a human would violate human dignity.D:Parents might clone a child to have"spare parts"in case the original child needs an organ transplant.E:Cloning is a radical challenge to the most fundamental laws of biology.F: Where did he come up with such a right?
Text 2 With so much focus on children’s use of screens,it's easy for parents to forget about their own screen use.“Tech is designed to really suck on you in,”says Jenny Radesky in her study of digital play,"and digital products are there to promote maximal engagement.It makes it hard to disengage,and leads to a lot of bleed-over into the family routine.”Radesky has studied the use of mobile phones and tablets at mealtimes by giving mother-child pairs a food-testing exercise.She found that mothers who sued devices during the exercise started 20 percent fewer verbal and 39 percent fewer nonverbal interactions with their children.During a separate observation,she saw that phones became a source of tension in the family.Parents would be looking at their emails while the children would be making excited bids for their attention.Infants are wired to look at parents’faces to try to understand their world,and if those faces are blank and unresponsive—as they often are when absorbed in a device－it can be extremely disconcerting foe the children.Radesky cites the“still face experiment”devised by developmental psychologist Ed Tronick in the 1970s.In it,a mother is asked to interact with her child in a normal way before putting on a blank expression and not giving them any visual social feedback;The child becomes increasingly distressed as she tries to capture her mother’s attention."Parents don't have to be exquisitely parents at all times,but there needs to be a balance and parents need to be responsive and sensitive to a child’s verbal or nonverbal expressions of an emotional need,"says Radesky.On the other hand,Tronick himself is concerned that the worries about kids'use of screens are born out of an“oppressive ideology that demands that parents should always be interacting”with their children:“It’s based on a somewhat fantasized,very white,very upper-middle-class ideology that says if you’re failing to expose your child to 30,000 words you are neglecting them.”Tronick believes that just because a child isn’t learning from the screen doesn’t mean there’s no value to it－particularly if it gives parents time to have a shower,do housework or simply have a break from their child.Parents,he says,can get a lot out of using their devices to speak to a friend or get some work out of the way.This can make them feel happier,which lets then be more available to their child the rest of the time.The oppressive ideology mentioned by Tronick requires parents to_____A.protect kids from exposure to wild fantasiesB.teach their kids at least 30,000 words a yearC.ensure constant interaction with their childrenD.remain concerned about kid's use of screens

共用题干Early or Later Day CareThe British psychoanalyst John Bowiby maintains that separation from the parents during the sensitive "attachment"period from birth to three may scar a child's personality and predispose to emotional problems in later life.Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails,and many people do believe this.But there are also arguments against such a strong conclusion.Firstly,anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies.For example,in some tribal societies,such as the Ngoni,the father and mother of a child did not rear their infant alone-far from it.Secondly,common sense tells us that day care would not be so widespread today if parents,care-takers found children had problems with it.Statistical studies of this kind have not yet been carried out,and even if they were,the results would be certain to be complicated and controversial.Thirdly,in the last decade there have been a number of careful American studies of children in day care,and they have uniformly reported that day care had a neutral or slightly positive effect on children's development.But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.But Bowlby's analysis raises the possibility that early day care has delayed effects.The possibility that such care might lead to,say,more mental illness or crime 15 or 20 years later can only be explored by the use of statistics.Whatever the long-term effects,parents sometimes find the immediate effects difficult to deal with.Children under three are likely to protest at leaving their parents and show unhappiness.At the age of three or three and a half almost all children find the transition to nursery easy,and this is undoubtedly why more and more parents make use of child care at this time.The matter,then,is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.Which of the following is derivable from Bowiby's work?A:Mothers should not send their children to day care centers before the age of three.B:Day care nurseries have positive effects on a child's development.C:A child sent to a day care center before the age of three may have emotional problems in later life.D:Day care would not be so popular if it has noticeable negative effects on a child's personality.
共用题干第一篇The Mystery of ClonesScientists have cloned goats,cats,cows,pigs and mice.Now it has been suggested by many commentators and scientists that it might be ethically acceptable to clone existing people in certain cases.One possibility is generating a replacement for a dying relative.All such possibilities,however,makes more and more people concerned that it would be possible that the clone is subjected to expectations and limitations based on the family's knowledge of the genetic"twin",so he or she would not be treated as an individual with independent personality.For the reason that human personality is only partly determined by genes,those assumptions might not be right.The clone of a shy person might behave quite differently if he or she is brought up in a family with encouraging atmosphere.Clones of writers,scholars,scientists or athletes are very likely to choose different careers because of chance event in early life.Some researchers have suggested the idea that couples,in which one part is infertile,might choose to make a copy of one or the other partner. But the notion raises the concerns that the child who is a copy of just one of a couple might not treat naturally,and it is not in the interests of the resulting kid.Moreover,the treatments of all known types of infertility are available nowadays;conventional therapies seem more ethnically acceptable to ordinary people's way of thinking,so the majority of population strongly opposed to allowing cloned human embryos（胚胎）to develop.However,the positive side of the cloning technology cannot be denied,for instance,cloning from cultured cells will provide essential medical opportunities.Scientists are trying to grow an embryo,cloned from a single cell of a human being with goals to design therapies for diseases which are currently untreatable.Of course,people's predictions about this new technology might be all wrong,because social attitudes change and unexpected developments take place.Only time will tell.But biomedical researchers who are dedicated to finding the potential of cloning have plenty to do.Maybe someday soon,a human will be cloned,and mankind will embark on a scientific and moral journey whose destination is not under his own control.
