Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly—the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were angry because they thought cloning would create more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific breakthrough.

Antinori,who is the head of a hospital in Rome,has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant(怀孕)with a cloned baby.Antinori refused to comment on the reports,but in March 2001 he said he hoped to produce a cloned embryo for implantation within two years.So far seven different kinds of mammals have already been successfully cloned,including sheep, cats and most recently rabbits.Doctors showed their doubt and were strongly opposed although they admitted that human cloning would finally come true unless there was a worldwide ban on the practice.Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology said,“I find it astonishing t hat people do this where the result can be foretold that it will not be a normal baby.It is using humans as guinea pigs.It makes people feel sick.”But Ronald Green,director of the Ethics Institute at Darmouth College in the US,said it was unlikely that an eightweek-old pregnancy would lead to a birth.So far all cloned animals have suffered from some different serious disorders,many of them dying soon after their births.Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one.“There are no benefits of cloned human beings,just harm,”said Dr Michael Wilks of the UK.1.What

humans according to the passage?A.They are against it.B.They support it.C.They pay no attention to it.D.They welcome it.3.What does the underlined word “ban” in the fourth paragraph most probably mean?A.Order that forbids cloning.B.Suggestion on carrying on cloning.C.Anger at cloning.D.Cheer for cloning.4.Which of the following statements is TRUE according to the passage?A.Doctor Severino Antinori is strongly opposed to cloning human beings.B.Up to now,seven kinds of animals have been cloned,including sheep,cats,humans and rabbits.C.Professor Rudolf Jaenisch is carrying on an experiment on cloning aneight-week-old embryo.D.Ronald Green doubts about the future successful birth of so-called cloned embryo.5、The Boy Made it!One Sunday, Nicholas, a teenager, went skiing at Sugarloaf Mountain in Maine. In the early afternoon, when he was planning to go home, a fierce snowstorm swept into the area. Unable to see far, he accidentally turned off the path. Before he knew it, Nicholas was lost, all alone! He didn’t have food, water, a phone, or other supplies. He was getting colder by the minute.Nicholas had no idea where he was. He tried not to panic. He thought about all of the survival shows he had watched on TV. It was time to put the tips he had learned to use.He decided to stop skiing. There was a better chance of someone finding him if he stayed put. The first thing he did was to find shelter from the freezing wind and snow. If he didn’t, his body temperature would get very low, which could quickly kill him.Using his skis, Nicholas built a snow cave. He gathered a huge mass of snow and dug out a hole in the middle. Then he piled branches on top of himself, like a blanket, to stay as warm as he could.By that evening, Nicholas was really hungry. He ate snow and drank water from a nearby stream so that his body wouldn’t lose too much water. Not knowing how much longer he could last, Nicholas did the only thing he could—he huddled(蜷缩) in his cave and slept.The next day, Nicholas went out to look for help, but he couldn’t find anyone. He followed his tracks and returned to the snow cave, because without shelter, he could die that night. On Tuesday, Nicholas went out again to find help. He had walked for about a mile when a volunteer searcher found him. After two days stuck in the snow, Nicholas was saved.Nicholas might not have survived this snowstorm had it not been for TV. He had often watched Grylls’ survival show Man vs. Wild. That's where he learned the tips that saved his life. In each episode(—期节目) of Man vs. Wild. Grylls is abandoned in a wild area and has to find his way out.When Grylls heard about Nicholas' amazing deeds, he was super impressed that Nicholas had made it since he knew better than anyone how hard Nicholas had to work to stay alive.1.What happened to Nicholas one Sunday afternoon?A.He got lost.B.He broke his skis.C.He hurt his eyes.D.He caught a cold.2.How did Nicholas keep himself warm?A.He found a shelter.B.He lighted some branches.C.He kept on skiingD.He built a snow cave.3.On Tuesday, Nicholas _____.A.returned to his shelter safelyB.was saved by a searcherC.got stuck in the snowD.stayed where he was4.Nicholas left Grylls a very deep impression because he _____.A.did the right things in the dangerous situationB.watched Grylls’ TV program regularlyC.created some tips for survivalD.was very hard-working6、根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

Unit 2 Cloning李仕才一、阅读理解。

If you're making determination for a healthier new year, consider a gut makeover(肠道清理)．Changing your microbe community(微生物群)，however, may not be easy，and nobody knows how long it might take.That's because the ecosystem already established in your gut determines how it absorbs and processes nutrients.So if the microbe community in your gut has been shaped by a daily diet of hamburgers and pizza，for example，it won't respond as quickly to a healthy diet as a gut shaped by vegetables and fruits that has a more varied microbe community.“The nutritional value of food is influenced in part by the microbe community that encounters that food，” said Dr Jeffrey Gordon，the senior author of the new paper and director of the Center for Genome Science and Systems Biology at the Washington University School of Medicine in St.Louis.“Nutritional components of a healthy diet have to be viewed from the inside out，” he said，“not just the outside in.”One of the questions the study set out to answer was how individuals with different diets respond when they try to improve their eating habits.The scientists harvested gut bacteria from humans，transplanted them into mice bred under germfree conditions，and then fed the mice either Americanstyle or plantba sed diets.The scientists then analyzed changes in the mice's microbe communities.Of interest，the scientists harvested the gut bacteria from people who followed sharply different diets.One group ate a fairly typical American diet，consuming about 3 000 calories a day，high in animal proteins with few fruits and vegetables.Some of their favorite foods were processed cheese and lunch meat.The other group consisted of people who were calorierestricted.They ate less than 1 800 calories a day and had carefully tracked what they ate for at least two years，sticking to a mostly plantbased diet and consuming far less animal protein than the other group，a third fewer carbohydrates(碳水化合物)and only half the fat.Thiscalorierestricted group，the researchers found，had a far richer and more diverse microbe community in the gut than those eating a typical American diet.They also carried several kinds of“good” bacteria，known to promote health，that are unique to their plantbased diet.“Perhaps the best way to shape a healthier microbe community is to eat morefiber by consuming more fruit，vegetables，whole grains，and nuts or seeds，” said Meghan Jardine，a dietitian who was not involved in the current study but has published articles on promoting healthy microbe communities.She urges people to aim for 40 to 50 grams of fiber daily，well above levels recommended by most dietary guidelines.1．What can we know from the first two paragraphs?A．Changing microbiome is fairly easy.B．Ecosystem in gut is shaped by carbohydrates.C．Nutritional components are determined by food intake.D．As to healthy diets，microbe community shaped by vegetables and fruit respond more quickly than that shaped by junk food.2．What can we learn about Meghan Jardine?A．She suggests eating as little as possible.B．She attaches great importance to fiber.C．She is one of the researchers of the current study.D．She advocates consuming more meat in daily life.3．What's the author's attitude toward gut makeover?A．Concerned. B．Opposed.C．Indifferent. D．Nervous.4．Which is the best title for the text?A．Microbe community in our gutB．A gut makeover for the new yearC．Dietary guidelines for daily dietsD．The best way towards a healthier microbe community【解题导语】本文是一篇说明文。

2019春高中英语人教版高二选修8练习：unit_2_cloning_word版含解析

Unit 2 Cloning[导语]从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整20年过去了，陈老仍然执着于此。

然而保护大熊猫，究竟要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100，000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.“Those who are against cloning have made their voices heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way to save endangered animals，”Chen said.Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.
