高中英语人教版选修8练习:Unit 2 Cloning含解析
高中英语 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 高中英语
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.

children’s classroom.His face showed a mix of fear and excitement,and he stayed close to his sister as he moved down the aisle.My wife and I sat together,alone there for the first time.I began to feel sad,a longing for something I couldn’t describe well.I glanced at my wife.A tear rolled down her cheek.She was feeling the same thing.I slid over,and we held hands.Our last child was entering the first grade,and we felt part of him slipping away.He’d be in school for a full day now.He’d be more independent,and need us less often.And,he’d never again be the toddler he once was.In our “stay positive”culture,many parents only see these times as a reason to celebrate.They see it as an inevitable change,and prepare themselves for the next challenge.But I couldn’t help feeling this.I didn’t want to bury my feeling of sadness.Those who protect themselves from these moments lose a great opportunity of growth.It is the kind of growth that results from pain,and makes us all more a part of the human family.Half an hour later,my son returned to us,his eyes twinkling.He was excited to tell us about his new experience.We listened to him,and his smiling face helped to ease the sadness.In fact,it was impossible not to feel happy for him.Loving_your_kids_is_not_always_easy.There are painful times when we see them moving away from us.But we must not avoid or run away from these feelings,for they give us the chance to increase our capacity for joy,while we are experiencing great sadness.16.The author’s son stayed with his sister close maybe because ________.A.he had to walk with the help of his sisterB.he wanted to be protected by his sisterC.he was not only scared but also very excitedD.he didn’t want to leave his parents alone17.When the author’s wife saw their son leave,she was ________.A.heartbrokenB.warm-heartedC.disappointedD.hopeful18.We can know from the third paragraph that________.A.it is wrong for parents to protect their childrenB.many parents are very cruel to their childrenC.it is very dangerous to meet the challengeD.children can grow by joining the human family19.The underlined sentence “Loving your kids is not always easy.”(in Paragraph 5) is most likely to tell us that________.A.it is difficult for you to love your kidsB.you’d better not love your kids any longerC.loving your kids sometimes makes you painfulD.you’re really happy to love your kids sincerely20.The author has written this passage in order to tell us that________.A.we shouldn’t allow our children to go to school earlyB.sadness is a normal feeling when our children leave usC.we should let our children live independentlyD.happiness is actually as important as sadnessBSitting across from a German couple and a Chinese mother and her child,we were waiting at the Guilin airport for our delayed flight to Shanghai.In this last week of our travel-study tour,my husband and I were savoring this short break by reading.I tuned out the languages I couldn’t understand.But it was an American accent that pulled my attention from my book.It also pulled the attention of three rows of people seated around us as the American barked,“Coming through!Coming through!”At the same time,an oversized man pulling an oversized carry-on passed our row.His wheeled bag caught the German’s feet.Turning to see what snagged his luggage,the American fellow yanked his bag so hard that it crossed over the man’s feet.It was then that my horror struck.There was no “I’m sorry”,no “Excuse me” and no “Pardon me” coming from this countryman of mine.While this wasn’t the first or last incident where I sighted discourteous,ill-mannered,rude Americans in China,each produced similar feelings.First,I was embarrassed that someone from my country was creating a negative impression of Americans.My second reaction was a desire to apologize.I wanted them to explain to the Chinese woman and her child,the German couple next to them,and everyone nearby that this was not typical American behavior.I wanted them to know “we” were all not like that.I never got to explain,or to nguage differences made that option impossible,and rational thinking made it inappropriate.And it turned out not to be a need.The German caught myeyes with a bit of head-shaking,smiling and eye rolling,which I returned,and it was clear that he knew we were Americans and was expressing that there was “no need”to apologize for “universal idiot behavior”.21.In the airport the author and her husband ________.A.were talking with a German coupleB.were having a good timeC.were enjoying reading togetherD.were worrying about their flight22.According to the author the man with an American accent was________.A.strongB.impoliteC.humorousD.generous23.The underlined word “snagged” (in Paragraph 3) means________.A.stoppedB.coveredC.touchedD.pushed24.Every time the author saw Americans’ bad behavior in China she always felt________.A.uneasy and apologeticB.scared and disappointedC.proud and comfortableD.nervous and miserable25.From this passage we can know that the author comes from________.A.GermanyB.ChinaC.JapanD.America1.A2.B3.C4.C5.B6.C7.D8.C9.A 10.A 11.C 12.A 13.B 14.C15.D 16.C 17.A

There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism.Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells. Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs ,cats, rabbits, and a gaur. All these clones were created using nuclear transfer technology.汉语⼤意:当媒体报道的克隆的消息,他们通常所说的只有⼀种称为⽣殖性克隆的类型。

The vehicle-named the Transition–has two seats, four wheels and wings that fold up so it can be driven like a car. TheTransition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.Around 100 people have already put down a $10,000 deposit to get a Transition when they go on sale, and those numbers will likely rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don’t expect it to show up in too many driveways. It’s expected to cost $279,000.And it won’t help if you’re stuck in traffic. The car needs a runway.Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The govemment has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.Mann said Terrafugia was helped by the Federal Aviation Administration’s decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find redatively easy to meet.1.What is the first paragraph mainly about?A.The basic data of the Transition.B.The advantages of flying cars.C.The potential market for flying cars.D.The designers of the Transition.2.Why is the Transition unlikely to show up in too many driveways?A.It causes traffic jams.B.It is difficult to operate.C.It is very expensive.D.It bums too much fuel.3.What is the government’s attitude to the development of the flying car?A.CautiousB.Favorable.C.Ambiguous.D.Disapproving.4.What is the best title for the text?A.Flying Car at Auto ShowB.The Transition’s Fist FlightC.Pilots’Dream Coming TrueD.Flying Car Closer to Reality四、七选五How to Care for a Pet FishTaking care of a pet is a big responsibility, so you should make sure you learn all about your pet before bringing it home. ①______ That' s because fish can give them a good idea of whether or not they'll be able to take care of a more complicated(复杂的) pet later on.First, choose what types of fish. ②______ They are easier to raise and give you enough experience to take care of fish and their tanks(水箱). Some kinds of fish do not get along with others, so you'll need to choose what kinds to buy.Next, make sure you have all of the necessary supplies. Fish need a fish tank. Make sure it is big enough for the number of fish. Fish tanks need a light and some machines to keep the water clean and at a comfortable temperature. ③______Now you can set up your aquarium(水族馆). Wash sand and decorations( 装饰物) clean and fill the bottom of the tank with them. ④______ Follow the instructions on the heater to heat up the water to the temperature your fish will need.

一、阅读理解(共8小题,每小题2分,共16分)AThink about the longest elevator ride that you’ve ever taken. Whether you rose five floors or 100, it probably took less than a few minutes. Now imagine riding in an elevator higher and higher as it climbs for nearly a day. When you reach the top floor, prepare for views that are really out of this world. You’ll be in space!Space elevators might sound like a crazy idea, but they’re something scientists have been working on for decades.Why would anyone want a space elevator? At the moment, riding in a capsule is the only way ordinary people can get to and from space. But those rides are very expensive — about $25 million per person per flight.Researchers are still figuring out the details about how a space elevator might work. One idea is stretching a very long cable — more than 37,000 kilometers — up to space from the earth’s equator (赤道). The location is important: Objects in space above the equator orbit the earth at the same speed that our planet turns. A weight on the end of the cable would stretch it tight. An elevator tied to the cable could use it to climb up and down.The only problem is that besides being long, this cable must also be very strong. Storms, including hurricanes might break it. One way to solve this problem is to stretchthe cable from the moon instead of from the earth. Airplanes designed to climb higher than a typical jet might take off from the earth and link up with the cable, which would be held in place by the pull of gravity from the earth. An elevator car waiting therewould then take riders the rest of the way to the moon. Fueled by solar power, theelevator could transport people and materials without much expense or effort per ride.So, when will you be taking your first space-elevator ride? Probably not for awhile.1. The first paragraph is presented by________. A. giving an example B. making a comparison C. asking questions D. analyzing causes2. Why have scientists been working on space elevators? A. To make trips to space cheaper. B. To help astronauts do research in space. C. To find a more convenient way to the moon. D. To prove an assumption which seems crazy.3. The underlined word “it” in Paragraph 4 refers to ________. A. the cable B. the equator C. an object in spaceD. a weight on the end of the cable此卷只装订不密封班级 姓名 准考证号 考场号 座位号4. Which part of a magazine may the article appear in?A. Science and technology.B. Sports.C. Literature.D. Entertainment.BWithin five years, a woolly mammoth (猛犸象)will likely be cloned, according to scientists who have just recovered well-preserved bone marrow (骨髓) in a mammoth bone.Russian scientist Siemyon Grigoriev and his colleagues are now analyzing the marrow, which they obtained from the mammoth, found in Siberian soil. Grigoriev and his team, along with colleagues from Japan, have announced that they will start a joint research project aimed at recreating the enormous mammal, which went extinct around 10,000 years ago. Mammoths used to be a common sight in North America and Eurasia. Many of our distant ancestors probably had regular face-to-face encounters with the elephant-like giants.The key to cloning the woolly mammoth is to replace the nuclei of egg cells from an elephant with those extracted from the mammoth’s cells. Doing this, according to the researchers, can result in embryos with the mammoth’s DNA. That has actually been known for a while.What have been missing are the woolly mammoth’s nuclei with undam aged genes. Scientists have been on a search for such nuclei since the late 1990s. Now it sounds like the missing genes may have been found.In the course, global warming may be responsible for the breakthrough. Warmer temperatures tied to global warming have melted ground in eastern Russia that is almost always permanently frozen. As a result, researchers have found a fair number of well-preserved frozen mammoths there, including the one that produced the bone marrow.Is it such a good idea, however, to clone animals that have long been extinct? For a while there has been some discussion of a real-life Jurassic Park setup containing such animals. Introducing these beasts into existing ecosystems could be like bringing in a potentially invasive species that would try to fill some space presently held by other animals. Even if the cloned animals were contained in special parks, there could still be a risk of spreading.So if the woolly mammoth is successfully cloned sooner rather than later, we’d probably be left with more questions and arguments than answers, at least in the short term.5. Which of the following would be the best title for the passage?A. How to clone a woolly mammothB. The woolly mammoth — an ancient speciesC. The research made by Russian and Japanese scientistsD. A woolly mammoth to be cloned6. Which of the following can be the key factor in cloning a mammoth?A. To find a living mammoth in North America or Eurasia.B. To use nuclei from a mammoth’s egg cells to replace the nuclei in an elephant’s egg cells.C. To find out when and where woolly mammoths lived on the earth.D. To find out if an cient mammoths are distant ancestors of today’s elephants.7. Which of the following best describes the writer’s attitude towards the future of cloning a mammoth?A. Uncertain.B. Indifferent.C. Positive.D. Disappointed.8. From the passage, we can learn that ________.A. some other extinct species have been cloned successfullyB. the mammoth used to be a very common speciesC. the clone of mammoths should be banned by lawD. a woolly mammoth will be successfully cloned this year二、语法填空(共10小题,每小题1.5分,共15分)Cloning has always been with us and is here to stay. It is a way of making ____1____ exact copy of another animal or plant. Cloning plants is straightforward while cloning animals is very complicated. The process of cloning is a difficult task ____2____(undertake). Many attempts to clone mammals failed. But finally the determination and patience of the scientists paid ____3____ in 1996 with a breakthrough-the cloning of Dolly the sheep.At first the fact ____4____ she seemed to develop normally was very encouraging. Then came the ____5____(disturb) news that Dolly had become seriously ill, which made cloning scientists cast down. Meanwhile, Dolly’s appearance raised a storm of ____6____(object) and had a great impact on the media and public imagination. ____7____(apparent) it became controversial. Although at present human egg cells and embryos ____8____(need)for cloning research are hard to obtain, newspapers wrote of evil leaders ____9____(hope) to clone themselves to attain their ambitions. Religious leaders also raised moral questions.

unit2 CloningⅠ.阅读理解AThere are many ways in which human cloning is expected to benefit humans.Dr Richard Seed, one of the leading supporters of humancloning technology, suggests that it may someday be possible tocompletely change the aging process because of what we learn fromcloning.Scientists believe that they may be able to treat heart attackvictims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the US and several other industrialised countries.There has been a breakthrough with human stem cells. Embryonic stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, and kidneys could be produced. By combining this technology with human cloning technology, it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer’s disease, Parkinson’s disease, heart failure, and other problems can be cured if human cloning and its technology are not banned.Though current treatments for infertility (不生育) are getting a fair amount of publicity in the news, they, in terms of percentages, are not very successful. Some data shows that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.语篇解读:本文作者从几个方面介绍了克隆人技术给人类带来了利益。
