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 isa 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.[词海拾贝]1．endangered adj.快要绝种的2．technique n．技巧，手法3．transplant v．移植4．pregnancy n．怀孕[问题思考]1．Do you think pandas

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. Some countries reformed their legal systems and ____10____(forbid) research into human cloning, but others like China and the UK, continued to accumulate evidence of the abundant medical aid that cloning could provide.三、短文改错(共10小题，每小题1分，共10分）假定英语课上老师要求同桌之间交换修改作文, 请你修改你同桌写的以下作文。

人教版英语选修8 Unit 2 Cloning 单元测试卷一、阅读理解1.British scientists have done something that many people thought was impossible: they created the first clone of an adult mammal（哺乳动物）．The clone, named Dolly, is a seven-month-old sheep, grown from a cell of an adult female sheep.What is a clone? A clone is a copy—a genetic copy. Genes are the instructions for life. They tell a cell what to do and how to do it. Genes make each individual plant or animal different and unique. But a clone has the same genes as the original organism（生物体）．Cloning is not new. Plants have been cloned for centuries. New plants are often grown from cutting from another plant. Also, plants like pineapples, strawberries and carnations（康乃馨）are sometimes cloned. One benefit of cloning is that we can make many copies of the best and healthiest plants.It has been much more difficult to clone animals. Frogs have been cloned, but they died as tadpoles, never living long enough to become adult frogs. Mice, sheep and cattle have been cloned from embryos（胚胎）．But Dolly is the first healthy clone of an adult mammal. How did they do it?(1) An unfertilized egg was taken from a sheep.(2) The egg nucleus（细胞核）was removed.(3) A cell was taken from the udder（乳房）of a pregnant（怀孕的）sheep.
