ACloning technology can only be applied to animals BA cloned animal can live longer than a normal one CPeople all over the world are happy about the birth of Dolly DCloning can produce valuable tissues and organs to cure human diseases2The reasons why people are anti-cloning include the following EXCEPT that _ Acloning may produce a real-life Frankensteins monster Bcloning might create more disease in the animal world Ccloning cant help those who want to clone their dead children Dcloning human embryos shows no respect for human life3Who is in favor of cloning human beings? AIan Wilmut BSeverino Antinori CThe author DThe Chinese scientist4What can be inferred from the last two paragraphs? AIf we interfere with nature，we will change the world to be what we want BIt is impossible to clone babies for women who cannot have ones CCloning human beings is illegal in many countries，so no scientists want to do so DWhether cloning human embryos is legal or not remains a matter of debate四、书面表达 （1）昨天我校举行了一场辩论赛，主题是“是否应该允许以医疗为目的的克隆”，辩论赛结果是支持克隆的一方获胜；观点如下：正方：1. 严重的疾病可以借助克隆技术。2. 克隆技术介入的治疗过程简单，对病人无害。3. 67%的美国人民支持以医学为目的的克隆。反方：1. 克隆本身没有安全保证。2. 克隆过程复杂并且以吸收大量的动物为代价，因此在欧洲至少有20个国家不允许克隆。3. 名人Pope John Paul 反对克隆。 （2）你班同学对于克隆人持不同意见，请你根据下表中的提示，用英语写一篇短文，介绍同学们的不同观点，并表达自己的看法。一些同学赞成的理由一些同学反对的理由你的看法1能使许多不孕患者实现做父母的愿望。2为许多不治之症找到新的治疗方案。3创造巨大的物质财富，有利于社会的进步。1会引起道德方面的问题。2可能成为恐怖分子的犯罪工具。3大量基因结构相同的“克隆人”可能诱发新型疾病的传播。答案与解析：一、单项选择1. B。句意：他看上去如此害怕，我想他看见可怕的东西了。第一空表示他看起来“感到害怕的”，所以用terrified。第二空是某种“可怕的，令人害怕的”东西。所以用terrifying；terrify是及物动词，表示“使某人害怕”。2. A。句意：他虽然已年过六十，但脸上几乎没有皱纹。wrinkle 皱纹；freckle 雀斑；spot斑点；dimple 酒窝。3. B。句意：警察追捕逃跑的窃贼，最后把他逮住了。chase 追赶，追逐；chain 拴住；cease停止；charter 包租。4. B。句意：如果你全心投入到这项工作中，你会在今晚之前完成它的。throw oneself into投身于。5. C。identical 完全相同的；intact 完整的；incredible 难以置信的；inconvenient 不方便的。句意：那位业余歌手在比赛中击败了众多的职业歌手，这是令人难以置信的，故选C项。6. B。句意：委员会决定举行一个会议，讨论随着最近法律的变更而出现的问题。arise from由产生，由引起，主语常是losses, difficulties等；arouse 唤醒，唤起，激发；raise提高，举起；rise 上升，升起。7. C。句意：那位拳击冠军马上就将那位缺乏经验的对手击昏了。knock against 碰一下；knock on 敲(门等)；knock out 击昏。8. C。句意：明天市长将陪同一个加拿大商团参观市区。accompany意为“陪伴，陪同”；coordinate意为“协调”；cooperate意为“合作”；associate意为“使联合，交往”。9. B。wish后面的宾语从句要用虚拟语气，此句与过去事实相反，故要用过去完成时态。10. A。短语bring back to life意为“使复苏，使复活”。句意：战后，那个小国家的人民致力于使国家复苏。二、完形填空1A。通读全文可知，本文讲述一位慈爱而又家境拮据的母亲为女儿婚礼攒钱的故事。母亲传给她的jewellery是常太太拥有的唯一值钱的东西。2B。语气转折。3A。上文讲靠出售jewellery而得到一半的钱。本句应表达还有一半到哪里去得到，而不是借或挣。4C。给别人打扫屋子(来挣钱)。5A。stay up意为“熬夜”，熬夜给别人缝制衣服挣钱。6B。给穿过村子的游客绣花挣钱。7A。gradually意为“逐渐地，慢慢地”。8D。慢慢地，攒的钱就多起来了。9B。由上文可知母亲很忙。10A。文末讲到wedding day。11A。由最后一段可知，另外一件好礼物不是某件物品，而是弟弟David来参加婚礼，故不能选B、C、D三个选项。12C。由下文“he lent her the money”可知，这里表达“需要钱”的意思。13A。常太太从来没有来借过钱，故她的亲戚觉得很奇怪。14C。always总是，一直；usually通常；never从来，绝不；sometimes有时；由此可知C项符合要求。15D。由下文可知进城去了，故应“穿上”最好衣服。16A。由18空后的“posted it”可知此处应是买机票。17A。把机票放入信封。18D。由下文可知是寄给David的。19C。这里没有别人，故是自言自语。20A。have在此表示“有，拥有”。有哥哥参加她的婚礼，Mary该有多高兴啊!三、阅读理解本文主要讲述了克隆技术以及克隆人所引起的争论。1D。细节理解题。根据第一段第二句话可知D项正确；根据第二段首句可知A项错误；从Dolly的例子可知克隆的动物不如正常的动物寿命长，故B项错误；C项与原文第二段第四句话相悖。2C。细节理解题。文中提到人们反对克隆技术的原因包括A、B和D三项；而根据第四段第一句“尽管克隆人类胚胎目前在很多国家属于非法，但是有些科学家已经开始加紧研究，以便降生一个克隆的人类婴儿”，并不能判断是否能够克隆出人们死去的孩子，且这也不是人们反对克隆的原因。故答案为C项。3B。细节判断题。根据文章倒数第二段第二句可知答案为B项。4D。推理判断题。通过最后两段，我们可以推断出：虽然克隆人在很多国家还不被认可，但是有些科学家已经开始了这方面的研究；对于克隆人是否合法现在还是一个存在争议的问题。故选D项。四、书面表达参考范文1：Yesterday there was a very exciting debate in our school about whether medical cloning should be allowed or not. After a lively discussion, a vote was taken and the side arguing for medical cloning won.The arguments for medical cloning were very strongly put by the team supporting the motion. They argued that serious illness and people who were losing their ability to move or think could be helped by medical cloning. They explained that the procedures would be safe, quick and with no problems for the patients. They showed that 67% of the people in America supported it. Their arguments were very convincing.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 animals had to be killed to produce one useable embryo for research. They explained that more than twenty European countries do not allow medical cloning research because of this. They quoted Pope John Paul . But their arguments were not so convincing.At the end of the debate, the audience left with a feeling of hope. They realized that diseases that seem terrible today may be able to be cured soon. Many people were excited and happy when they left the hall. I was among them.参考范文2：Should Human Cloning Be Allowed?Should human cloning be allowed? My classmates take different attitudes towards it.Some of my classmates are in favour of human cloning. They think it will help those who are not able to have children realize their dream of being parents. Whats more, treatments for many incurable diseases can be found with its help. They also think it creates great wealth and is of great benefit to society progress.However，other classmates are against human cloning. As far as they are concerned, it will give rise to moral questions. Worse still, terrorists may use it as a tool. Cloned people with lots of genes arranged in the same way may cause the spread of new diseases.In my opinion, human cloning should be fully developed. As an old saying goes，every coin has two sides. If we can make proper use of human cloning, I believe it will benefit us all.
