　　Ⅱ.阅读理解

　　Cloning is suggested as a means of bringing back a relative, usually a child, killed unfortunately. Some parents can understand that wish, but it must first be recognized that the copy would be a new baby and not the lost child. Here lies the_difficulty,_for the sad parents are seeking not a new baby but a return of the dead one. Since the original would be fondly remembered as having particular talents and interests, would not the parents expect the copy to be the same? It is possible, however, that the copy would develop quite differently. Is it fair to the new child to be placed in a family with such unnatural expectations?

　　Copying is also suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interests. But because personality is only partly the result of genetic inheritance, conflicts would be sure to arise if the cloned child failed to develop the same interests as the original. What if the copy of Einstein shows no interest in science? Or the baseball player turns to acting? Success_also_depends_on_fortune. What if the child does not live up to the hopes and dreams of their parents simply because of bad luck?

　　Every child should be wanted for itself, as a person. In making a copy of oneself or some famous person, a parent is purposely specifying the way he or she wishes that child to develop. In recent years, particularly in the U．S., much importance has been placed on the right of individuals to reproduce in ways that they wish. So I suggest there should be a greater need to consider the interests of the child and to reject these suggested uses of cloning.

　　16．The underlined part “the difficulty” in Paragraph 1 refers to ________.

　　A．cloning a baby is difficult

　　B．it's difficult to give birth to a new baby

　　C．the dead child can't come back again

　　D．the cloned baby can't replace the lost child

　　17．According to the passage，one of the reasons why couples usually decide to clone babies is ________.

　　A．to bring back a child killed unfortunately

　　B．to exchange their children

　　C．to develop the same interests as their child

　　D．to succeed in making fortune

　　18．The sentence “Success also depends on fortune” implies that ________.

　　A．the result may be unpredictable

　　B．the child does not live up to the parents' hopes

　　C．the cloned child fails to develop the same interest as the original

　　D．the baseball player turns to acting

　　19．We CAN'T conclude that ________ according to the observation made by the author.

　　A．it's important to consider the interests of the child rather than the suggested uses of cloning

　　B．parents can't expect to get the lost child back by cloning a new baby

　　C．much importance should be placed on the right of parents to reproduce babies in ways that they wish

　　D．every child should be wanted as a unique individual

　　Ⅲ.任务型阅读

　　下面文章中有5处需要添加小标题。请从以下选项(A、B、C、D、E和F)中选出符合各段意思的小标题。选项中有一项是多余选项。

　　A．The great impact and progress in genetic engineering

　　B.Worries about privacy protection

　　C.Worries about medical use of genetic engineering

　　D.Genetic knowledge helps to predict diseases

　　E.Possibilities of misuse genetic knowledge

　　F.The application of genetic engineering in the medical fields

　　20．________

　　Current research into the human gene system is helping us understand why people have predispositions (易患某病倾向) to certain diseases.Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer.Even before birth, we are able to do genetic screenings to determine what a child’s genetic disorder will be.Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings.

　　21．________

　　The implications of this knowledge are astonishing.In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases.Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes (中风). But with the research that is now being conducted, we may find cures for many more diseases.In the near future, genetic experimentation will also allow parents to select the traits of their children.Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.

　　22．________

　　Many people, however, are unwilling to accept the possibilities genetic research allows.For example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against.Another problem is that many people do not want to discover their weakness.What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?

　　23．________

　　Many people believe that history has not always shown human decision­making to be bright when it comes to ethical (道德的) choices.Jeremy Rifkin is probably the most well known opponent of genetic engineering.He believes that humans are not responsible enough to experiment with genes and should not “play God”. He asks, “Just because it can be done, does that mean it should be done？” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society.

　　24．________

　　One of the fears expressed about genetic experimentation involves privacy.Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns.But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions.The possibilities for discrimination are obvious.

　　答案

　　课时作业(三十七)

　　Ⅰ.1.D　考查同位语从句。根据语意“我不知道那位记者从哪里得到的信息”可知，此处应用where引导同位语从句，解释idea的具体内容，所以这里选D项。

　　2．A　考查表语从句。that引导的表语从句，而且不可以省略。

　　3．B　考查同位语从句。句意：他在信中承诺：在即将到来的圣诞节来看望我。由句子结构可以看出promise后的从句非常完整，不缺少任何句子成分；由题意可知该从句用以说明promise的内容，所以可判断出是一个同位语从句，因为是在陈述一个事实，故引导词要用that。

　　4．C　考查定语从句。先行词warmer climates在从句中作地点状语(表示抽象的地点)，故用where引导。

　　5．C　考查动词辨析。句意：威廉发现读书越来越难，因为他的视力正逐渐变弱。disappear“消失”；fall“落下，(数量﹑ 数目)下降”；fail“(指健康)衰退，变弱，消失”；damage毁坏。

　　6．A　考查forbid的用法。这里考查的是forbid sb. to do sth.的被动语态。句意：众所周知，无论是谁，在公共汽车上都是禁止吸烟的。

　　7．C　考查交际用语。C项意思为“别费心了，不必要了”，与Let's come to the point(让我们言归正传吧)相吻合。A项 “不用谢”；B、D两项语气太生硬，有失礼貌。

　　8．C　考查冠词用法。第一空后名词strike与空前介词on构成固定短语go on strike，意为“罢工”，故用零冠词；第二空后名词是可数名词的单数，表泛指，前加不定冠词，故选C。

　　9．A　考查固定短语辨析。句意：争吵过后，我尽力去消除我们之间的误会，但是我的努力看起来都白费了。in vain “白费地，徒劳无益地”；in case “免得，以防”；in time “及时，迟早”；in trouble “处于困境”。故选A。

　　10．A　考查冠词用法。honor指的是具体的一件事，所以前面要用不定冠词，第二空修饰的是最高级，所以用定冠词the。句意：中国研发出世界上速度最快的电脑是一个极大的荣誉。

　　11．B　考查动词短语辨析。put off意为“推迟，取消”。句意：他们本来打算那天到乡下去，但听说交通堵塞就作罢了。put away放好；put up举起，张贴，建造，提供(住宿)；put down放下，写下。

　　12．A　考查forbid doing sth.的用法。句意：有些国家的法律禁止在不适当的时间和地点播出广告。由于advertisements与动词show之间为被动关系，所以选A。

　　13．C　考查介词的选择和宾语从句。句意：他做这件事的方式和我们以前所习惯的方式不同。“与……不同”用be different from…结构，what引导的宾语从句，相当于the way that…；which也可以引导宾语从句，但是表示疑问，而此处不表疑问。

　　14．B　考查非限制性定语从句的关系词。第一空是as引导的非限制性定语从句(可放句首)；第二空是which引导的非限制性定语从句。句意：正如人们所预料的只有5人参加了聚会，这令女主人很失望。

　　15．D　考查副词辨析。shortly “很快，不久”。句意：过了没有多久，警察拦住了那辆汽车，两个人都被逮捕了。immediately立刻，马上；promptly 敏捷地；deliberately故意地。均不合句意。

　　Ⅱ.克隆现在得到了很好的应用。能不能克隆小孩子呢？本文对这个问题进行了探讨，认为克隆“小孩”有很多困难，关键是克隆技术再好，也代替不了“原来的孩子”。

　　16．D　词义推测题。 克隆小孩的困难在于“克隆小孩代替不了死去的小孩”，故选D。

　　17．A　细节理解题。夫妻克隆小孩的原因有两个：“bringing back a relative, usually a child, killed unfortunately”和“have the child of their dreams”。

　　18．A　句意理解题。 成功还要靠运气，暗示着结果不可预知。

　　19．C　推理判断题。由最后一段“…much importance has been placed on the right of individuals to reproduce in ways that they wish”可知答案为C。

　　Ⅲ.20.D　21.F　22.C　23.E　24.B
