Later, the embryo (胚胎) was put into the reproductive tract of a dog to carry out the pregnancy. Baby passed away of natu

15、ral causes. After about two months, Baby “No. 2” was cloned in September 2017.Karitas brought her home at 8 weeks old. If this technology can make someone so incredibly happy, why is there debate surrounding it? Some might argue that people gain an enormous benefit by having the opportunity to recon

16、nect with an animal identical to one they once loved so dearly. Its true that a cloned animal has a very good chance of looking like the original dog. But theres no guarantee a clone will be identical. The way units of hereditary (遗传的) material, called genes, function can varyeven between animals wi

17、th identical sets of genes. Environmental factors can also have a great effect on how an organism develops both its physical attributes and temperament.Another ethical concern is that dog cloning has only about a 20 percent success rate. That means the process of collecting egg cells to create an em

18、bryo and implanting the cloned embryo into a surrogate dog must usually be done many times before a healthy puppy is born. These procedures involve conducting operations on unwilling animals. Klitzman says that performing any surgery carries risks to animals. He explains that surgeries should be don

19、e only if they benefit an animals health or advance medical or scientific research. “We are subjecting animals to harm when there is a nonessential benefit，” he says, “and that is ethically problematic.”Many critics ask: Why clone a dog or a cat when there are nearly 8 million animals in the US wait

20、ing to be adopted? “There are plenty of shelter dogs who need a loving home，” says Milutinovich, a researcher.篇章导读：本文是一篇说明文。失去宠物的痛苦或许只有经历的人懂。如果有一项技术可以让你心爱的宠物“死而复生”，你会支持吗？1Why does the writer tell the story of Karitas?ATo stress the high price for cloning pets.BTo reflect the ethical problems of clon

21、ing.CTo prove the advanced technology of cloning.DTo explain the Americans love for pets. 答案：C推理判断题。根据第一段内容可知，Karina的宠物狗死了之后，克隆了一个，说明了克隆技术已经非常先进。2What can cloning pets be of help to people?ACloning pets might accelerate emotional healing.BA cloned pet is similar to its original.CGenes often change i

22、n the course of cloning.DThe success of cloning depends on its environment. 答案：A推理判断题。根据第三段第一句可知，克隆宠物令人们有机会可以和自己曾经最爱的宠物重新建立联系，也就是可以帮助宠物主人尽早抚平情绪上的创伤。3What does Klitzman consider an ethical problem?APeople do operations on sick animals.BSurgeries are done for dangerous animals.CDoing cloning is for me

23、dical researches.DCloning does no good to animals and humans. 答案：D推理判断题。根据倒数第二段最后两句可知，他认为克隆动物在对人类没有必要的好处的时候，还令动物处于风险之中，这样就产生了伦理上的问题。因此对动物和人类都没好处。4Whats Milutinovichts emotions about cloning pets?AUncaring. BDisapproving.CSupportive. DDoubtful. 答案：B推理判断题。根据最后一段内容可知，Milutinovicht认为庇护所里有很多狗等着被领养，需要一个充满

24、爱的家，为什么要去克隆已经死了的宠物呢？说明他对这一现象持反对态度。故选B。China became the first country to clone a monkey using nonreproductive cells, scientists said on Thursday. By December 2017, the Chinese Academy of Sciences had created two clone macaques (猕猴) named “Zhongzhong” and “Huahua” by nuclear transferring of body cells

25、any cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.Telra, a monkey born in 1999, was the worlds first evercloned monkey, but it was done using a simpler method called embryo splitting (胚胎分裂), and couldnt be gene

26、tically modified to suit experimental needs, said Pu Muming, a leading researcher at the Chinese Academy of Sciences. “Cloning a monkey using body cells has been a worldclass challenge because it is a primate (灵长类) that shares its genetic makeup and all of its complexity with humans，” he said.“For d

27、rug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly and bad for the environment and produces inaccurate results because each monkey might have different genes，” Pu said.“By cloning a monkey using body cells, we can reproduce a large number of genetic

28、ally identical monkeys in a short amount of time, and we can even change their genes to suit our needs，” he added. “This can save time, cut down experiment costs, and produce more accurate results, leading to more effective medicine.”Sun Qiang, director of the nonhuman primate research facility at t

29、he institute, said most of the drug trials were currently done on lab mice. However, drugs that work on mice might not work or even have severe side effects on humans because the two species are so different.Monkeys and humans are both primates, so they are closely related and testing on monkeys is

30、supposed to be as effective as testing on humans. This achievement will help China lead the world research in an international science project related to study of primate brains.篇章导读：本文是一篇科普类说明文。文章讲述了中国在克隆技术上取得的成就中国是第一个使用非生殖细胞克隆猕猴的国家。5What do we know about the two clone macaques?AThey were the first

31、 monkeys ever cloned in the world.BThey were created using reproductive cells.CThey would be fed to suit experimental needs.DThe technology used to create them was similar to that of creating Dolly.答案：D细节理解题。根据第一段最后一句“This was the similar technology used to create the famous clone sheep Dolly in 199

32、6.”可知，克隆猕猴使用的技术与著名的克隆羊多莉使用的技术是相似的。6Which of the following can replace the underlined word “identical” in the fourth paragraph? ASame. BSimilar.CRelevant. DClose.答案：A词义猜测题。通过阅读画线词所在段落可知，该段与上一段内容形成对照，上一段叙述了由于猴子基因不同造成的坏处，本段讲述了各种好处原因是用这种方法可以复制出基因相同的猴子，据此推断，画线词意为“相同的”，故选A。7What can be learned from the pa

33、ssage?APu Muming and Sun Qiang were doing most work in cloning the two macaques.BGenetic research on monkeys can be seen as effective as that on humans.CMice share the same genetic makeup and complexity with humans.DScientists can reproduce cloned monkeys to cut down experiment costs.答案：B推理判断题。根据最后一

34、段第一句“Monkeys and humans are both primates, so they are closely related and testing on monkeys is supposed to be as effective as testing on humans.”可知，猴子和人都是灵长类，他们关系密切，因此对于猴子的基因研究应该与对人类的研究一样有效。8This passage can be most probably read in _. Aa science magazine Ba guidebookCa storybook Da brochure答案：A推理

35、判断题。纵观全文可知，本文主要讲述克隆技术方面的研究成果，中国成功用非生殖细胞克隆出猕猴。因此推断文章很可能在科技杂志上找到。.短文改错(2019辽宁省五校协作高三联合模拟题)Dear Joy，How are you doing? Here is an exciting news for you.

38、 been to design a tiny cooler that people can wear around the wrist. I think it will be a idea for the competition. We can make a small air conditioner to the temperature of the wearer. do you think of my suggestion? Looking forward to reply.Yours，Zhang Xin1删除an考查冠词。news为不可数名词，不用冠词修饰，故an多余。2inon考查介词

39、。在具体的某一天应用介词on。3rule后加that考查同位语从句的连接词。分析句子结构可知，rule后的句子为同位语从句，解释说明rule的具体内容，从句不缺句子成分且意思完整，故用that引导该同位语从句。4ButSo考查连词。该句与前一句为因果关系而非转折关系，故将But改为So。5partnerspartner考查名词。作者邀请Joy一人作为队友，因此应该用可数名词单数。6longedlonging考查动词的语态。you与long之间是主动关系且表示动作从某一时间开始，一直持续到现在并且可能继续下去，故用现在完成进行时的主动形式。7wonderfullywonderful考查形容词。名词前应该用形容词修饰，故将wonderfully改为wonderful。8controllingcontrol考查非谓语动词。分析句子结构可知，此处应用动词不定式作目的状语，其中to为不定式符号而不是介词，故将controlling改为control。9HowWhat考查疑问词。What do you think of . 为固定句式，意为“你觉得怎么样？”故将How改为What。10youyour考查代词。此处表示：期待你的回复。名词reply前应用形容词性物主代词，故将you改为your。
