What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame，they may be famous persons but not heroes.Madonna and Michael Jackson are famous，but who would claim that their fans find life more abundant?Heroes are catalysts (催化剂)for change.They have a vision from the mountain top.They have the skill and the charm to move the masses.They create new possibilities.Without Gandhi，India might still be part of the British Empire.Without Rosa Parks and Martin Luther King，Jr.，we might still have segregated(隔离的)buses，restaurants，and parks.It may be possible for largescale change to occur without leaders with magnetic personalities，but the pace of change would be slow，the vision uncertain，and the committee meetings endless.一．根据短文，写一篇30词左右的摘要____________________________________________________________________________________________________________________________________________________________________________________________________________________________二．根据所读短文，选择最佳选项1．Although heroes may come from different cultures，they ________.

There is a guy Tyrell who is almost completely blind. Tyrell was all smiling for about a week. He's normally a quite happy kid, but I could tell this was different from the normally silly smile I see. Wednesday morning my curiosity finally got me to ask him why.He told me that he was going to ride his new 3-wheeled bike when he got home. He couldn't control his happiness. When he got off, he gave me a smile. A smile will forever be in my heart.The next morning, I noticed that his eyes were quite puffy (浮肿的). So were his mother's. I asked them why. She explained that was due to many hours of tears the night before. She said that Tyrell got to ride the bike once before he had to come in for dinner and was promised he could ride it again afterward. He left it in the back yard where they thought it would be safe.However, after dinner, the bike was nowhere to be found. They immediately broke into tears because they knew the thing that he treasured so much was stolen. She called her close friend to find some comfort.The friend called her up later and said that she forgot to tell Tyrell's mom that she had something for them and asked if it would be OK to bring it over. She, of course, was still crying from the thought that another bike would be impossible to afford and said yes. The friend brought over a huge box, in which there was a brand new bike for Tyrell.When they noticed what was in the box, they thanked their angel and cried even harder, not of sadness but of joy, and thankfulness.6. Why did the writer stress the guy's smile repeatedly in the first two paragraphs?A. His smile gave the writer a deep impression.B. The writer liked his happy smile very much.C. It set off how serious the loss of bike caused.D. The smile showed the happy ending of the story.7. Tyrell's mom cried so sadly at the lost bike because ____.A. her son wouldn't ride the bike any moreB. her family couldn't afford another bikeC. she felt very sad for the lost bikeD. she had just bought the bike for her son8. We can conclude from this story that ____.A. there are good people out thereB. offering someone helps is better than stealing from himC. the loss of the bike puts the family into a sad situationD. one can obtain happiness from helping othersCGoing to college has been such a new experience for me. Everything is different from when I was in high school. One thing I've noticed is that I haven't been focusing on my coursework like I planned.I thought I would spend most of my college life studying. But since I've been in college, about 60 percent of my time has been devoted to social life, while only 40 percent of my time has been devoted to my studies. I never knew I would make so many friends in such a short time.It's been so overwhelming (无法抵抗的)! I'm not saying that making friends is bad, but I'm starting to realize how much socializing has cut down on the time I should have spent on studying.Needless to say, that has to be changed.I've realized that I really don't want to spend an extra year or two here just because I slacked off as a freshman. So the first thing I'm going to do is to cut down on the amount of time I spend socializing. I will also have to say goodbye to a good part of the activities I like to attend.It's really difficult to cut these things out of my life, but I have to choose: I can have a full-time social life and fail college, or I can learn to balance my time between friends and studying and keep good grades. I think I'll stick to that second option!I may be a little strict on myself, but I'm here to get an education, not to learn how to socialize more! I want to have fun at college, but at the same time, I want to get a good education and have a bright future!9. What did the writer realize about his first year at college?A. He doesn't work as hard as in high school.B. Teachers don't care about him any more.C. He could make quite a lot of friends.D. He could spend much time on study.10. The writer makes a decision that he will ____.A. devote himself to his study rather than making friendsB. say good-bye to all his college activitiesC. cut down all his social life to have a good educationD. try not only to study well but also to have fun at college11. The underlined phrase “slack off” in the fifth paragraph is closest in meaning to “____”.A. do one's bestB. spare no effortC. have a good timeD. make less effort12. We can infer from the passage that the writer will ____ at college.A. spend more time on studyB. make a lot of friendsC. take more activitiesD. cut down his studying timeDAfter a couple has had their first child, to their disappointment they became infertile and couldn't have more children. Cloning would enable such a couple to have a second child, perhaps a younger twin to the child they already have. Many couples have difficulty having children, and sometimes it is impossible for couples to have children because they are infertile. Cloning would allow these couples to have children.It is hard to tell someone that they cannot use cloning to have children when no other possible ways to have children are available. This is one reason why it is difficult to decide whether cloning is moral or not. The following are some of the reasons why cloning should be allowed.Through cloning, research can progress. We possibly can learn more about cell. We may develop technology to allow easier genetic testing and fixing problems such as spinal cord injuries, cancer, and many more.Cloning organs for organ transplants (移植) is one of the major practical reasons that cloning should be allowed. There is always a high demand for organs. Some argue for the cloning of humans to create extra body parts. Others talk of just wanting to clone an organ to replace a faulty organ.Rejuvenation (恢复青春) is also a key argument for advocates (提倡) of cloning. Some scientists believe that injecting cloned healthy heart cells into damaged heart tissue will lead to healing of the heart. By combining the technology for cloning and the technology for growing human stem cells, conditions like Alzheimer's, Parkinson's, and some other ageing disease may be curable. The possibilities are endless and may be left undiscovered if human cloning is forbidden.13. The underlined word “infertile” in Para. 1 means “____”.A. unable to have childrenB. too poor to grow cropsC. poor in pregnant knowledgeD. unable to afford to bring up children14. How many reasons does the writer give in this passage about why cloning shouldbe allowed?A. 2.B. 3.C. 4.D. 5.15. Which of the following statements is NOT true?A. Cloning babies for infertile couples is moral.B. Through cloning, research work in cells can make great progress.C. Cloning cells can make some diseases concerning ageing curable.D. Cloning technology may help improve medical technology.16. From the passage, we can know the writer's attitude toward human cloning is ____.A. negativeB. supportiveC. uninterestedD. opposingEBARCELONA (Reuters) —“Galactic Suite”, the first hotel planned in space, expects to open for business in 2012 and would allow guests to travel around the world in 80 minutes.Its architects say the space hotel will be the most expensive in the galaxy, costing $4 million for a three-day stay.During that time guests would see the sun rise 15 times a day and use Velcro suits to crawl (爬) around their pod (分离舱) rooms by sticking themselves to the walls like Spiderman.Company director Xavier Claramunt says the three-bedroom hotel's joined up pod structure, which makes it look like a model of molecules, was based on the fact that each pod room had to fit inside a rocket to be taken into space.“It's the bathrooms in zero gravity that are the biggest challenge,” says Claramunt. “How to provide enough space for more private activities of the guests is not easy.”But they may have solved the issue of how to take a shower in weightlessness — the guests will enter a spa room in which bubbles of water will float around.When guests are not admiring the view from the windows of their pod rooms'， they will take part in scientific experiments on space travel.“There is fear associated with going into space,” said Claramunt. “That's why the shuttle rocket will remain fixed to the space hotel for the duration of the guests' stay, so they know they can get home again.”“But,” says Claramunt, “I'm hopeful that the impact of seeing the earth from a distance will stimulate (激发) the guests' urge to value and protect our planet.”17. Which of the following might be the best title for this passage?A. “Galactic Suite”: the first hotel planned in spaceB. Fly me to the moon: space hotel sees 2012 openingC. Fly to the moon: a greatest dream for humansD. Building a space hotel: a dream or a reality?18. Which of the following is NOT what guests can do in “Galactic Suite”?A. Watching the sunrise.B. Taking a weightless shower.C. Doing scientific experiments.D. Walking in space.19. Suppose we will travel to space, the following will be the problems we must solve EXCEPT ____.A. weightlessnessB. fearC. pollutionD. money20. The writer's writing this passage is to ____.A. prove space travel is possibleB. tell us a bright dream of going to spaceC. explain some problems existing in space travelD. report a space hotel to be completed by 2012IV 单词拼写1. The role of the news m_________ informing public opinion is of great importance.2. The small town looks e__________ as it did when it was built 200 years ago.3. I'm sorry to d_________ you so late, but I was wondering if I could use your phone.4. For a teacher to hit a child is not just m__________ wrong but also illegal.5. These profits are based on the a__________ that prices will continue to rise.6. The treatment won't cure her — it m__________ stops the pain.7. The law f__________ the sale of cigarettes to people under the age of 16.8. We have worked out a new set of p__________ for using this machine.9.

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。

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.

也使关于克隆人的争论变得更加现实。
Human cloning is the creation of a genetically identical copy of an existing or previously existing several highly public claims，human cloning still appears to be a is no solid scientific evidence that anyone has cloned human embryos at present.In 2023，a group in South Korea published a paper in the journal Science in which it claimed to have created a cloned human embryo in a test ，an independent scientific institute later found no proof to support the claim and，in January 2023，Science announced that the paper had been withdrawn.In January 2023，Dr Samuel Wood and Dr Andrew French in California announced that they successfully created the first 5 fully grown human embryos using DNA from adult skin cells，aiming to provide a source of viable embryonic stem Dr Wood stated that if that were possible，using the technology for reproductive cloning would be both immoral and 5 cloned embryos were destroyed.The various forms of human cloning are scientific，governmental and religious organizations oppose reproductive ，some people have considered the idea of growing organs separately from a human organism—in doing this，a new organ supply could be established without the moral problem of harvesting them from humans.【词海拾贝】1．genetically ad v.从遗传学角度，从基因角度2．viable adj.切实可行的，有望实现的3．reproductive adj.生殖的，再生产的【问题思考】1．What is human
