12、itas, from Florida, learned that her 14yearold dog Baby was ill and would soon pass away. Karitas decided to proceed with genetic preservation for cloning. Later, the embryo (胚胎) was put into the reproductive tract of a dog to carry out the pregnancy. Baby passed away of natural causes. After about

13、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 reconnect with an animal iden

14、tical 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 with identical sets of gen

15、es. 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 embryo and implanting the

16、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 done only if they benefit a

17、n 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 waiting to be adopted? “Ther

23、 Chinese scientists had created two clone macaques named “Zhong Zhong” and “Hua Hua” by nuclear transfer of somatic cellsany cell in the organism other than reproductive cells. This was the similar technology used to create the famous clone sheep Dolly in 1996.“Cloning a monkey using somatic cells h

24、as been a worldclass challenge because it is a primate (灵长类) that shares its genetic makeup with humans.” Pu Muming said.“For drug and other lab tests, scientists have to purchase monkeys from all over the world, which is costly, bad for the environment and produces inaccurate results because each m

25、onkey might have different genes，” Pu said.“By cloning monkeys using somatic cells, we can produce large numbers of genetically identical (相同的) offspring in a short time, and even change their genes to suit our needs，” he added. “This can save time, cut down experiment costs, and produce more accura

26、te results, leading to more effective medicine.”“This achievement will help China lead the world research in an international science project related to neural (神经的) mapping of primate brains，” he said. “However, biology labs from the United States, Japan, and European countries are also very able,

27、and they will quickly catch up with China after the monkey cloning technology is made public，” Sun Qiang added. “This means we have to innovate continuously and work extra hard this year to stay ahead，” he said.篇章导读：本文是一篇说明文。中国科学家使用非生殖细胞成功地克隆了猴子，成为世界上第一个使用非生殖细胞克隆灵长类动物的国家。这项科研成果为更准确、更有效、更经济的新药动物试验铺平了

33、去拜访朋友李雷，他母亲真诚地邀请“我”留下吃午饭。指代句中的I，宾格用me，故us改为me。2第三句：waswere考查主谓一致。与句中three people保持一致，动词be用复数，故was改为were。3第三句：删除all考查副词。altogether “总计，总共”；all together “全都在一起”。此处指总共三个人吃午饭，故删除all。4第四句：dishdishes考查名词。dish是可数名词，此处eight修饰名词，应用复数，故dish改为dishes。5第四句：finishedfinish考查情态动词。情态动词couldnt后用动词原形，故finished改为finish

34、。6第五句：thrown前加was考查动词的时态和语态。句中the food和谓语动词throw之间是被动关系，指食物被扔掉。与全文时态保持一致，这里应用一般过去时，故在thrown前加was。7第六句：begbegging考查非谓语动词。see sb. doing sth. “看到某人正在做某事”，此处指看到无家可归的人正在乞讨，故beg改为begging。8第六句：wherewhich考查定语从句的引导词。此处是非限制性定语从句，用关系代词which指代前面整个句子，故where改为which。9第八句：WhatHow考查副词。此处是感叹句，表示“多么希望”，用how来表示感叹，故What改为How。10第八句：willwould考查虚拟语气。句中wish后的宾语从句用虚拟语气，表示对将来情况的虚拟，从句形式为“主语would动词原形”。故will改为would。
