Early or Later Day Care
The 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.

共用题干第三篇The Age of being Bullied and Its EffectThe age at which kids first fall victim to bullying（欺辱）could influence how strongly they are affected,suggests a new study.And,surprisingly,it is not the youngest kids who are hurt the most in the long term. Bullying can have long-lasting effects,but particularly when it begins in adolescence（青春期）,the researchers say.People subjected to either oral or physical bullying are known to be at greater risk for developing depression,anxiety disorders or to behave violently.But not everyone reacts in this way.Children bullied for the first time before their adolescence seem to get over it,but those who are victimized for the first time late on in adolescence seem to become more aggressive or are more likely to turn to drink as a means of coping. These are the conclusions of psychologist Matthew Newman and his colleagues from the University of Texas at Austin,U.S.The team gave questionnaires to nearly 1,500 college students regarding their experience of physical and psychological bullying before adolescence一before high school一and in late adolescence一at high school.They assessed mood and mental state,judging by signs of anxiety or depression,such as sleeplessness.The group was also questioned about how they would react to certain challenges,such as being embarrassed or provoked.People who were bullied all revealed slightly higher levels of stress.But while those bullied earlier in life seemed to respond normally to provocation,people bullied for the first time late in adolescence are more withdrawn and sensitive to violence.The best solution was strong social support,whether from friends,family or school.Those with no one to share their problems were suffered the most.So perhaps it is best not to shelter children completely from bullying early on,suggests Newman."They may get stressed,but unhealthy coping really jumps out when they are bullied for the first time later on."The effects are likely to be related to the developing stress hormone system, which matures during adolescence,he concludes.Studies show abnormal stress responses in adult animals that experience social stress or aggression from other animals during adolescence.The author most probably agrees that,when a child falls victim to bullying,his parents should_______.A:help and comfort him right awayB:not shelter him completely from itC:wait until his stress hormone system maturesD:not interfere in until the child wants to share
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

S. to Start $3.2 Billion Child Health Study in JanuaryA study that will cost $3.2 billion and last more than two decades to track the health of 100,000 U.S.children from before birth to age 21 will be launched in January,U.S.health officials said on Friday.Officials from the U.S. government's National Institutes of Health said they hope the study,to be conducted at 105 locations throughout the United States,can help identify early-life influences that affect later development,with the goal of learning new ways to treat or prevent illness.The study will examine hereditary（遗传的）and environmental factors such as exposure to certain chemicals that affect health.Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air,water,dust and materials used to construct their residences,the NIH said.Officials said more than $200 million has been spent already and the study is projected to cost $3.2 billion."We anticipate that in the long term（从长远说来）,what we learn from the study will result in a significant savings in the nation's health care costs,"Dr. Duane Alexander,who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development,told reporters.The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up（使报名从事）pregnant women whose babies will then be followed to age 21.Some of the early findings will be about factors behind pre-term birth（早产）,which has become more common in recent years,according to Dr. Peter Scheidt of the NIH,who heads the study.The people taking part will be from rural,urban and suburban areas,from all income and educational levels and from all racial groups,the NIH said.Researchers will collect all the following EXCEPT__________.A:genetic samples from people in the studyB:biological samples from people in the studyC:samples from the homes of the women and their babiesD:samples of air and water from hospitals

共用题干Separation may Help Improve MarriageMarriage is big lately；actually it's unmarriage that seems to be capturing our attention.From the award-winning American Beauty to the Bruce Willis-Michelle Pfeiffer movie,The story of Us,the institution of marriage is being turned inside out,and it's not a pretty sight.To judge by these films,modern marriage involves a lot of broken crockery and busted expactations.While many current Hollywood depictions of marriage may be overly pessimistic, statistics in America are alarming:each year half as many Americans get divorced as marry.Marriage counselors say couples often choose to separate as a last-ditch effort to change their relationship and possibly themselves.“Many trial separations don't work because they're not‘authentic'.They're just one person's way of getting out of the relationship,” says Harriet Lerner,author of the book The Dance of Anger.But a separation can give couples time to calm down,renegotiate the rules of the relationship and gain some needed distance.For a separation to work,it needs to be well defined.Constance Ahrons,directors of the Marriage and Family Therapy Training program at the University of Southern California, says“structured separations”tend to be the most productive.Couples facing separation do best if they establish some basic ground rules first.They should mutually agree on the length of the separation一Ahrons says three to six months is average一and both must continue to work on their own problems during that time,either with or without a counselor.Couples should agree not to see lawyers during their separation.Lawyers have a way of moving marriage toward divorce.During their period of trial separation,couples should not pursue each other at all,either to fight or to reconcile,but should agree in advance on what kind of contact they will have.Separated couples can agree to speak on the phone for a prearranged period,for instance,or meet once a week.Some therapists advise their clients to agree not to talk to each other about their relationship during these encounters and to use the time apart to reflect on their own lives and see what they can change about themselves.If there are children involved,Ahrons says,both parties need to agree on all the ground rules having to do with kids.Parents should also be aware that repeated separations and reconciliations are difficult and confusing for children.Ahrons says a separation,while painful,can help keep the anger down and give a couple time to think.If both are unsure about the future of the marriage,it can provide a time-out, during which they can see what life would be like without the other.“Sometimes”,Ahrons says,“a separation can lead back into marriage.Sometimes it leads to divorce.But if couples are able to clarify things,it will improve their marriage一or,make their divorce better.”All of the following statements are true except that______.A:The population of divorced American is almost half of that of married American annuallyB:it is necessary for the couple who want their separation to be successful to set certain rulesC:it will make the children puzzled if their parents separate and come back into harmony again and againD:Lawyers are more needed than the therapists and marriage counselors during the couple's separation

共用题干The Sandwich GenerationToday people often look forward to their middle age as a time when they will be able to take things easier. After their children are grown,they expect to enjoy the life they have worked hard to create .However,the reality is often very different. In middle age,many people discover that they have two ongoing responsibilities:one is to look after their aging parents,and the other is to help their young adult children deal with the pressures of life.Around the world,there are mil-lions of people who are“sandwiched”in between the older and the younger generations.Some-times there may be two or three generations living in the same household-a situation that is corn-mon in many Asian countries and in some parts of Europe .In other cases,a couple may be taking care of parents and children,but they do not live with them.There are two important reasons for the rise of the sandwich generation.First,people are liv-ing longer than they used to.In the early nineteenth century,the average life expectancy for adults in the United States,for example,was about 40,whereas today people live to an average age of 75 .Therefore,children are taking care of their parents over a longer period of time.The see-ond reason is that these days,young adults often live with their parents for a longer time than they did in the past. This is often for financial reasons.It's also more common for today's young adults to return home during or after college if they need financial or emotional support.Young adults feel sandwiched between their financial responsibilities and their desire to enjoy life .They may have to cover expenses that their parents cannot.They may have to manage their parents' financial and legal affairs.They may have to prepare for their parents' future needs,such as special medical care or a move to a nursing home. This can be a traumatic（长期困扰的）ex-perience for everyone.Caring for adult children presents challenges as well,and caregivers have to resolve important questions:How can financial responsibilities be shared among members of the household?How can household chores be shared?What is the best way to ensure everyone's privacy?Successfully cop-ing with these issues can avoid a lot of stress for the whole family.The financial and emotional pressures on the sandwich generation can be overwhelming. However,this time in life also has its rewards.It can be a time to rediscover the special qualities of one's parents or children.It can also provide a valuable opportunity to spend more time with them. However,in order to survive this difficult period in their lives,the members of the sand-wich generation must remember that they also need to pay attention to their own needs and look af-ter the quality of their own lives.They can't be totally selfless. Why do some young adults choose to live with their parents these days?A:.They need support from their parents to deal with their financial problems.B:.They want to help their parents to take care of their aging grandparents.C: They are too young to be independent from their parents.D: They are more emotional than the young adults in the past.
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 statements is NOT an argument against Bowlby's theory?A:Many studies show that day care has a positive effect on children's development.B:The fact that there are so many nursery schools today shows that day care is safe.C:The separation of young children from their parents is common in some traditional societies.D:Parents find the immediate effects of early day care difficult to deal with.

问答题Today, thanks to advances in brain research, we know that reading with a child has intellectual, emotional and physical benefits that can enhance the child’s development. The intimacy of sharing books and stories strengthens the emotional bonds between a parent and child, helps a child learn words and concepts, and actually stimulates the growth of a baby’s brain. Scientists have discovered that children whose parents read and talk to them during the first three years of life create a stronger foundation for future reading success.
