Congratulations, It Will Be A Boy!
Until just a few years ago,making a baby boy or a girl was pretty much a hit-or-miss affair. Not anymore .Parents who have access to the latest genetic testing techniques can now predeter-mine their baby's sex with great accuracy,as Monique and Scott Collins learned to their delight two years ago,when their long-wished-for daughter Jessica was born after genetic prescreening（基因筛选）.
And baby Jessica is just the beginning. Within a decade or two,it may be possible to screen kids almost before conception（怀孕）for an enormous range of attributes（特性）,such as how tall they are likely to be,what body type they will have,their hair and eye color,what sort of ill-ness they will be naturally resistant to, and even,conceivably（可想见地）,their IQ and person-ality type.
In fact,if gene therapy lives up to its promise,parents may someday be able to go beyond weeding out（筛去）undesirable traits and start actually inserting the genes they want-perhaps e-ven genes that have been crafted（创造）in a lab. Before the new millennium is many years old, parents may be going to fertility clinics（生殖诊所）and picking from a list of options the way car buyers order air conditioning and chrome alloy（铬合金）wheels."It is the ultimate shopping ex- perience:designing your baby,"says biotechnology critic Jeremy Rilkin,who is appalled by the prospect."But in a society used to cosmetic surgery（整容手术）,this is not a big step."
The prospect of designer（定制）babies,like many of the ethnical conundrums（难题）posed by the genetic revolution,is confronting the world so rapidly that doctors,ethicists（伦理学家）, religious leaders and politicians are just starting to grapple with（与……进行格斗）the implica- tions-and trying to decide how they feel about it all.
They still have a bit of time .Aside from gender,the only traits they can now be identified at the earliest stages of development are about a dozen of the most serious genetic diseases.Gene therapy in embryos（胚胎）is at least a few years away. And the gene or combination of genes responsible for most of our physical and mental attributes has not even been identified yet. Besides, say clinicians,even if the techniques for making designer babies are perfected within the next decade,they should be applied in the service of disease prevention,not improving on nature.

参考答案
参考解析
解析：第三段的开头说到“if gene therapy lives up to its promise, parents may someday be able to go beyond weeding out undesirable traits and start actually inserting the genes they want"，由此可见，只有选项C与原文相符。选项A“选择婴儿的性别”，这是将基因技术运用于胚胎的最初阶段就可以实现的，而不是该技术发展一段时间后才可以实现的。选项B“预先确定婴儿性别”，这与选项A类似，同样不能选。选项D“鉴别基因的无序状态”，这在文中没有提及，所以不选。
根据第二段可知“在怀孕前挑选婴儿的优良品质”是一二十年后的事，排除B。根据第三段可知“在婴儿基因中加入父母希望孩子拥有的基因——甚至是在实验室中人为创造的基因”，这是基因疗法按照预期不断发展、走向成熟后才能实现的事情，由此可以排除C和D。而根据第一段“as Monique and Scott Collins learned to their delight two years ago,when their long-wished-for daughter Jessica was born after genetic prescreening", 可以知道选项A符合题意。
阅读完题干后应立即回到原文，细读Jeremy Rifkins的那一番话，前半句“It is the ultimate shopping experience: designing your baby”还不能确切体会出他的态度，但接下来，作者描述Rifkins为基因技术的发展前景所震惊“who is appalled by the prospect"，震惊一词至少可以说明Rifkins是不赞成先将基因技术用于胚胎的。而后半句“But in a society used to cosmetic surgery, this is not a big step.”就明确表明7 Rilkins的立场：这一技术并不稀奇，不值得大肆宣扬，从这里可以看出其态度是批评性的。
根据第四段内容“就像基因革命所带来的许多道德上的困惑一样，通过基因疗法来设计婴儿的这一前景，使得各方人士，如医生、伦理学家、宗教领袖和政治家，开始试图理解这一技术的含义，并试图决定他们对待这一技术的态度”，可以判断A正确。然后再一一分析后三个选项。选项B“设计婴儿是纯粹科学方面的事，不会引起道德争论。”文中没提及“设计婴儿是纯粹科学方面的事”，而认为“不会引起道德争论”则明显不符合原文。选项C“设计婴儿的前景已经引起了各方强烈谴责”，而原文只说各方人士开始关注这一技术，并未引来谴责。选项D“人们关心设计婴儿可能会伤害到科学”，这在文中没有提及，所以也不选。 最后一段说，当今基因技术尚不完善，可以为自己的孩子挑选优良品质也是几十年后的事，而且医界人士也表态说“将来这些技术也应该用来服务于疾病预防，而不用来改变自然”，所以有关人士还有时间来考虑究竟应该对基因技术作出什么样的评价。这些都在劝慰人们不要对该技术的发展太过担心。

Many post-80s couples are complaining that going to the movies, shopping or attending parties have become impossible since their kids were born. That s the way most parents are living their lives, no weekends of their own, no time to visit friends, not even a chance of promotion in their jobs.Asking help from their parents might be a way out,but problems are that some out aging parents are not strong enough to take care of the kids, and that the kids may also become too spoiled by their grandparents.Then, here comes a solution: families with kids can form. a small group, and parents of each family can take turns to look after all the kids in this group on weekends. Thus, other parents can have some quiet time and feel free to do something they ve been planning for a long time. At the same time, the kids can make new friends and won t be hanging around their parents all day long. This is baby-pooling.46.

第一篇Human EvolutionBeing a man has always been dangerous.There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity,and among 70-year-old there are twice as many women as men. But the great universal of male mortality is being changed.Now,boy babies survive almost as well as girls do. This means that,for the first time,there will be an excess of boys in those crucial years when they are searching for a mate. More important,another chance for natural selection has been removed. Fifty years ago,the chance of a baby(particularly a boy baby)surviving depended on its weight. A kilogram too light or too heavy meant almost certain death.Today it makes almost no difference.Since much of the variation is due to genes,one more agent of evolution has gone.There is another way to commit evolutionary suicide:stay alive,but have fewer children.Few people are as fertile as in the past. Except in some religious communities,very few women have 15 children.Nowadays the number of births,like the age of death,has become average.Most of us have roughly the same number of offspring. Again,differences between people and the opportunity for natural selection to take advantage of it have diminished.India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples.The grand mediocrity of today一everyone being the same in survival and number of offspring means that natural selection has lost 80%of its power in upper-middle一class India compared to the tribes.For us,this means that evolution is over;the biological Utopia has arrived.Strangely,it has involved little physical change.No other species fills so many places in nature.But in the past 100,000 years一even the past 100 years一our lives have been transformed but our bodies have not. We did not evolve,because machines and society did it for us.Darwin had a phrase to describe those ignorant of evolution:"they look at an organic being as savage looks at a ship,as at something wholly beyond his comprehension."No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were,they will look just like us.Which of the following would be the best title for the passage?A:Sex Ration Changes in Human Evolution.B:Ways of Continuing Man's Evolution.C:The Evolutionary Future of Nature.D:Human Evolution Going Nowhere.

Until the early 20th century failure to bear a son was grounds for divorce.South Koreans greatly preferred boys,who could not only support their parents financially but also carry out ancestral rites.When ultrasound technology became widespread in the 1980s,many South Koreans used it to detect female femses and then have them aborted.Sex ratios became skewed.In response to these trends the South Korean government made it illegal for doctors to reveal the sex of a fetus,Following the Asian financial crisis of 1997,many women took part-time jobs to supplement the family income.Parents noticed,and began to invest more heavily in educating girls.In 2015 three-quarters of South Korean female secondary-schoolers went to university,compared with two-thirds of their male peers.Since 2009 expectant parents have been allowed to know the sex of their baby after 32 weeks'gestation.Many will have found out before,from doctors who trust that parents'attitudes have changed.

When Teen Dating Turns Abusive and ViolentWhen teens start dating,parents' worries grow.__________(46)Nearly 10 percent of teenagers experience some form of violence in their dating relationships,according to the U.S.Centers for Disease Control and Prevention.Dating violence encompasses physical,emotional and sexual abuse,the CDC notes.___________ (47)A study in the January issue of Pediatrics found that teens who had experienced dating violence were more likely to binge drink,smoke,have depression symptoms,think about suicide and experience additional intimate partner violence than were their peers who'd never experienced dating violence.Often,though,abusive behavior starts with teasing and name-calling,which teens may see as a normal part of a relationship but which,according to the CDC,can lead to more serious violence, such as hitting or rape.Nancy Diaz,a domestic violence consultant who has provided services to Outreach in New York City,said that when she explains verbal abuse to teens,many think it's just normal conversation. __________(48) "It's the cycle of violence,"Diaz said.If a teen girl slaps a teen boy,the boy often says it's not abuse because it doesn't hurt,but Diaz explains that it is._________(49)"That's rape,but the girls don't think of it as rape,"Diaz said.For parents,protection starts with knowing the person their teen is dating."Invite them in,or offer to drive them somewhere," Diaz said."Just make sure you know who they're connecting with."__________(50)"Look for sores,bruises or scratches,and check out what they're doing on social media like Facebook."________（46）A:Often their own mothers,who may be young,have spoken to them in just that way.B:Beyond the immediate effects of violent relationships,longer-range impacts loom.C:She said that some gangs initiate girls by forcing them to have sex with all of the gang's members.D:Many violent relationships bring much physical harm.E:Discovering that abuse is occurring can be hard,but"watch out for social isolation,with-drawal from friends and activities,"Diaz said.F: Experts say that dating violence should be on their list of concerns.

AIDSThe World Health Organization(WHO)says as many as 10 million persons worldwidemay have the virus that causes AIDS（艾滋病）.Experts believe about 350, 000 personshave the disease.And one million more may get it in the next five years. In the UnitedStates,about 50,000 persons have died with AIDS.The country's top medical official says more than 90 percent of all Americans who had the AIDS virus five years ago are dead.There is no cure for AIDS and no vaccine（疫苗）or medicine to prevent it. However, researchers know much more about AIDS than they did」ust a few years ago.We now know that AIDS is caused by a virus.The virus invades healthy cells,including white blood cellsthat are part of our defense system against disease.It takes control of the healthy cell's genetic material and forces the cell to make a copy of the virus.The cell then dies.And the virus-caused particles move on to invade and kill more healthy cells.The AIDS virus is carried in a person's body fluids.The virus can be passed sexually or by sharing instruments used to take intravenous（进入静脉的）drugs. It also can be passed in blood products or from a pregnant woman with AIDS to her developing baby.Many stories about the spread of AIDS are false.You cannot get AIDS by working or attending school with someone who has the disease.You cannot get it by touching drinking glasses or other objects used by such persons.Experts say no one has gotten AIDS by living with,caring for or touching an AIDS patient. A.pregnant woman with AIDS cannot pass the virus to her developing baby.A:Right B:Wrong C:Not mentioned

Congratulations, It Will Be A Boy!Until just a few years ago,making a baby boy or a girl was pretty much a hit-or-miss affair. Not anymore .Parents who have access to the latest genetic testing techniques can now predeter-mine their baby's sex with great accuracy,as Monique and Scott Collins learned to their delight two years ago,when their long-wished-for daughter Jessica was born after genetic prescreening（基因筛选）.And baby Jessica is just the beginning. Within a decade or two,it may be possible to screen kids almost before conception（怀孕）for an enormous range of attributes（特性）,such as how tall they are likely to be,what body type they will have,their hair and eye color,what sort of ill-ness they will be naturally resistant to, and even,conceivably（可想见地）,their IQ and person-ality type.In fact,if gene therapy lives up to its promise,parents may someday be able to go beyond weeding out（筛去）undesirable traits and start actually inserting the genes they want-perhaps e-ven genes that have been crafted（创造）in a lab. Before the new millennium is many years old, parents may be going to fertility clinics（生殖诊所）and picking from a list of options the way car buyers order air conditioning and chrome alloy（铬合金）wheels."It is the ultimate shopping ex- perience:designing your baby,"says biotechnology critic Jeremy Rilkin,who is appalled by the prospect."But in a society used to cosmetic surgery（整容手术）,this is not a big step."The prospect of designer（定制）babies,like many of the ethnical conundrums（难题）posed by the genetic revolution,is confronting the world so rapidly that doctors,ethicists（伦理学家）, religious leaders and politicians are just starting to grapple with（与……进行格斗）the implica- tions-and trying to decide how they feel about it all.They still have a bit of time .Aside from gender,the only traits they can now be identified at the earliest stages of development are about a dozen of the most serious genetic diseases.Gene therapy in embryos（胚胎）is at least a few years away. And the gene or combination of genes responsible for most of our physical and mental attributes has not even been identified yet. Besides, say clinicians,even if the techniques for making designer babies are perfected within the next decade,they should be applied in the service of disease prevention,not improving on nature. Which of the following best expresses Jeremy Rifkin's attitude toward designing babies through gene therapy?A: Strongly supportive.B: Cautiously welcome.C: Uncommitted.D: Critical.
