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 ________. A．generally possess certain inspiring characteristicsB．probably share some weaknesses of ordinary peopleC．are often influenced by previous generationsD．all unknowingly attract a large number of fans2．According to the passage，heroes are compared to highvoltage transformers inthat ________.A．they have a vision from the mountaintopB．they have warm feelings and emotionsC．they can serve as concrete(具体的)examples of noble principlesD．they can make people feel stronger and more confident3．Madonna and Michael Jackson are not considered heroes because ___________________.A．they are popular only among certain groups of peopleB．their performances do not improve their fans morallyC．their primary concern is their own financial interestsD．they are not clear about the principles they should follow4．Gandhi and Martin Luther King are typical examples of outstanding leaders who ___________.A．are good at demonstrating their charming charactersB．can move the masses with the skill and the charmC．are capable of meeting all challenges and hardshipsD．can provide an answer to the problems of their people5．The author concludes that historical changes would ___________________________. A．be delayed without leaders with inspiring personal qualitiesB．not happen without heroes making the necessary sacrificesC．take place if there were heroes to lead the peopleD．produce leaders with attractive personalitiesBI work as an aid on a school bus. 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.

Although it may be years before aquaculture yields(产出) really large quantities of food, it is already partially successful. One of its successes is the growing of oysters(牡蛎)．Oyster farming is a big new business on Cape Cod, where large crops of oysters have been harvested. The waters there were famous for delicious oysters until the supply gave out about fifteen years ago. “There’s a whole generation of people who have never eaten oysters，”says Karl Touraine, marketing director of Aqua Dynamics Corporation, a company that grows oysters on strings hanging from metal racks(金属架). “For about twenty years the oyster has been in short supply, and our aim is to change this by using new, modern growing techniques，”he explains.“Wareham, on Cape Cod, is the first place in the United States where oysters are being grown on racks just off the bottom of the sea，”says Hank McAvoy of the National Marine Fisheries Service in Gloucester. “But there’s nothing new about offbottom raising, ”Mr. McAvoy adds. “It’s been done successfully in Norway and Australia and, in the last few years, in Spain. The Japanese have used this form of aquaculture for years, and they’re the most successful, with a yearly crop of fortysix thousand pounds of shelled oysters to the acre.”The Aqua Dynamics group grows oysters on strings, away from the bottom so that the oysters’enemies cannot reach them. “When an oyster can avoid enemies and live in unpollutedwater with plenty to eat, he’ll grow fat in four years，”Karl Touraine explains. “Oysters will attach themselves to almost anything they can，”he continues. “At Wareham, we use shells which we tie with nylon strings hanging from metal racks. We lower the strings into the water, leaving at least a foot of water between the lowest shell and the bottom.”“So far the growth has been excellent and the taste is just delightful，”Mr. Touraine notes happily.【解题导语】本文是一篇说明文。

In reality, about 80 percent of this Arctic island is covered by a sheet of ice—and now that ice is melting fast. As a result, NASA has sent a robot to help save the island’s ice.To determine how to do that, scie ntists need to learn more about how and why Greenland’s ice sheet is changing. But sending human researchers to study the ice sheet on snowmobiles and in aircraft can be expensive and time-consuming.So a group of college students at a NASA engineering summer camp came up with an alternative. They invented a robot known as GROVER. On May 3, NASA sent GROVER to Greenland to begin gathering data on the changes that the ice sheet is undergoing.Last summer alone, more than 97 percent of Greenland’s icy surface experienced some melting. Some scientists predict that in 2，000 years, the entire ice sheet will be one big puddle(水坑) because of rising temperatures in the region. That’s bad news. If the ice sheet completely melts, sea levels will rise. Rising sea levels around the world could bring about severe flooding, and some small islands could even disappear beneath the waves.That’s why, during the next month, GROVER will travel for more than 400 miles over the ice sheet. GROVER will be able to work longer and gather more data than any scientist on a snowmobile could. The 6-foot-tall, 800pound robot is powered by solar energy. It will be able to run anytime throughout the day or night because the sun never sets below the horizon(地平线) during the Arctic summer.“Robots like GROVER will give us a new tool for glaciology(冰川学) studies，”says NASA glaciologist Lora Koenig.Scientists hope this is just the beginning for GROVER. If the robot completes its first test, NASA plans to send GROVER out to explore the ice sheet for many months at a time.【解题导语】本文是说明文。

AI've loved books for as long as I can remember. When I was a child and my mother finished washing the evening dishes, she'd read books to me like Curious George and Little Black Sambo in her quiet voice. I always enjoyed listening to the stories, but I wanted to learn to read so that I could read to myself.When I was in first grade I read Go Dog Go by myself. One weekend morning while my parents were still asleep, I got up and read the whole book. When my parents woke up, I told them what I'd done. First they felt quite astounded and couldn't believe their ears, but they soon felt proud.Finally, I got a job in a bookstore and started buying books at a 30% discount (折扣). I kept every book I bought and whenever I looked at the books on my book shelf I felt a lot of excitement and energy. I loved all my books and I began collecting a lot of books. I have a home office with twelve book shelves and two large book cases. My office was filled with books. Every shelf was filled with books and the built-in desk that was completely covered by books that ran across the whole surface of the desk. I even had books lying on the floor.There was one big problem with this. My wife wanted to use the built-in desk and she repeatedly asked me to create space for her. I finally decided to clear out some of the books. In fact, I removed about half thebooks I owned. Not only was the desk completely clear, some book shelves were only half full. To my surprise, I felt a new sense of peace and freedom.语篇解读本文是记叙文。

Ⅰ阅读理解ACreative Alarm ClocksDumbbell(哑铃) alarm clockIt is not a real dumbbell, but you have to shake it up and down 30 times to stop the alarm clock. And there is no stop button. Of course you will be totally refreshed by then. Don’t be lazy and take some exercise in the morning!Target alarm clockThe alarm is ringing at the time you set it for! Do you see the target? Then hit it to stop the sound with a laser gun(激光枪). Of course you have to be fully awake if you don’t want to miss the target.Flying alarm clockI’m sure you won’t be able to simply ignore this alarm as you usually do, because it flies! Its propeller(螺旋桨) flying off the alarm is the key. Before the frightening alarm sounds drive you crazy, you’d better quickly put the key back.BanclockHave you been keeping a pocketful of change for some time without knowing what to do with it? Maybe you can put those coins in your alarm. This is both an alarm clock and a money box. It only stops ringing if you put a coin in it.IQ alarm clockWhat about a brain workout in the morning? IQ alarm will go off and ask you a set of IQ questions. Don’t even think about removing the battery, because it is hard to open. The only way to shut it off is to answer all questions correctly.Mr. Bump-off-the-wall alarm clockAn alarm clock is so annoying when you are too tired and sleepy to get up. You can release your anger on Mr. Bump. It looks like a blue ball covered with “bandages”. Just throw this alarm at the wall to silence it.【解题导语】本文是一篇说明文。
