第一节：完形填空（共15小题；每小题2分，满分30分）Tome Lee is determined to help people suffering from multiple sclerosis (MS) (硬化症). Sometimes he 1 a 300-mile bike ride in two days to prove it.“It’s a terrible disease,” Lee, 72, said, “I’ve met a lot of people with MS in the last 19 years. I’ve been 2 by their strength of character. They’re a very 3 group of people.” That courage inspired Lee to find his own. Although he enjoyed biking as a child 4 up in Ireland, he didn’t start riding long 5 until he worked for Westinghouse in Minnesota. It was 1991 when he did his first 150 miles in two days. He’s been pedaling(骑自行车) ever since.This weekend, Lee will ride from Miami to Key Largo during a biking event called the Maroon MS 150 Bike 6 . In September, he will ride from Kerry to Derry in Ireland where he will 7 300 miles in two days. Between the two events, he plans to 8 thousands of dollars. He sends letters to 100 people to collect the money, and most of the money he’s collected has 9 to the National Multiple Sclerosis Society. Lee enjoys 10 himself to achieve more. In 1992, he 11 to ride from Boca, Raton to Jacksonville and back. He did the ride for nine years. “I collected more than I 12 did.” he said.Here’s Lee’s key to a successful ride: drink water, eat every hour, ride 13 and never think about how far you’re riding. It’s not keeping 14 that helps Lee finish a bike ride, although he rides his bike 50 to 60 miles every week. He said, “I just have a lot of stamina (耐力)，which is very 15 for long races, and I’m strong –willed.”1. A. makes B. does C. has D. gets2. A. persuaded B. troubled C. encouraged D. excited3.

This was expressed by the equation E = mc2. But bombs were not what Einstein had in mind when he published this equation.In 1929, he publicly declared that if a war broke out he would "refuse to do war service, direct or indirect...." His position would change in 1933, as the result of Adolf Hitler's coming into power in Germany.Einstein's greatest role in the invention of the atomic bomb (原子弹) was signing a letter to President Franklin Roosevelt urging that the bomb be built because some physicists feared that Germany might be working on an atomic bomb. Among those concerned were physicists Leo Szilard and Eugene Wigner. But they had no influence with those in power. So in July 1939 they explained the problem to someone who did: Albert Einstein. After talking with Einstein, in August 1939 Szilard wrote a letter to President Roosevelt with Einstein's signature on it, which wasdelivered to Roosevelt in October 1939.Germany had invaded (入侵) Poland the previous month, the time was ripe for action. That October research of a-bomb began but proceeded slowly because the invention of the atomic bomb seemed distant and unlikely. In April 1940 an Einstein letter, ghost-written by Szilard, pressed the researchers on the need for "greater speed".As the realization of nuclear weapons grew near, Einstein looked beyond the current war to future problems that such weapons could bring. He wrote to his friend about his fear about the future use of the a-bomb.The atomic bombings of Japan occurred three months after Germany gave in.In November 1954, five months before his death, Einstein summarized his feelings about his role in the creation of the atomic bomb: "I made one great mistake in my life...when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification---the danger that the Germans would make them?26.What can we learn about Szilard and Wigner"A. They were not as influential as Einstein.B. They had cheated their friend Einstein.C. They were to blame for the invention of nuclear weapons.D. They had a purpose of destroying the world.27.Einstein realized his mistake in __________.A. co-operating with his workmatesB. inventing the atomic bombC. publishing his equationD. signing the letter to Roosevelt28.We can conclude that Einstein __________.A. assisted with the invention of atomic bombB. directly participated in the invention of the atomic bombC. was not involved in the invention of atomic bomb at allD. contributed to the invention of atomic bomb29.Please decide the order of the following events according to the passage.a. Einstein's letter reached President Roosevelt.b. The atomic bombs attacked Japan.c. Germany invaded Poland. d. Germany gave in.e. The equation E = mc2 was published.f. The research of a-bomb started.A.c,e,a,f,b,dB. a,e,b,d,f,cC. e,c,a,f,d,bD. e,c,b,f,a,d30.The best title for the passage would be __________.A. A Story of Albert EinsteinB. Albert Einstein and the Atomic BombC. It was Unfair for EinsteinD. How the Atomic Bomb was InventedBYou might think that "global warming" means nothing more than a rise in the world's temperature. But rising sea levels caused by it have resulted in the first evacuation（撤离）of an island nation—the citizens of Tuvalu will have to leave their homeland.During the 20th century, sea level rose 8—12 inches. As a result. Tuvalu has experienced lowland flooding of salt water which has polluted the country's drinking water.Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol（京都协议书）, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions（导致温室效应的气体排放）, which are a main cause of global warming.“By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.Tuvalu is not the only country that is vulnerable （易受影响的）to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.31. The text is mainly about _____ .A. rapid changes in earth's temperatureB. bad effects of global warmingC. moving of a country to a new placeD. reasons for lowland flooding32. According to scientists, the DIRECT cause of more and fiercer storms in Tuvalu is ___. .A. greenhouse gas emissions in industrialized nationsB. higher surface water temperatures of the seaC. continuous global warmingD. rising sea levels33. Laupepa was not satisfied with the United States because it did not ______.A. agree to reduce its greenhouse gas emissions.B. sign an agreement with TuvaluC. allow Tuvaluans to move to the USD. believe the problems facing Tuvalu were real34. The country whose situation is similar to that of Tuvalu is _____.A. AustraliaB. New ZealandC. the MaldivesD. the United States35. Which of the following words has the similar meaning as the word “forefathers”in the fourth paragraph?A. citizensB. relativesC. Former generationsD. Future generationsCThere are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little and will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may come across many problems at their schools.You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, itmay not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.36. Open education allows the students to ______.A. grow as the educatedB. be responsible for their futureC. develop their own interestsD. discover subjects outside class37. Open education may be a good idea for the students who ______.A. don't enjoy learningB. worry about gradesC. do well in a traditional classroomD. are responsible for what they do in life.38. Some students will do little in an open classroom because _____.A. there are too few rules B．they hate activitiesC. open education is similar to the traditional educationD．they worry about the rules39. Which of the following is NOT mentioned in the passage?A. Some traditional teachers do not like it.B. Many teachers do not believe in open education.C. Teachers may have problems in open classrooms.D. The teacher’s feelings and attitudes are important to the students.40. Which of the following best summarizes the passage?A. Open education is a really complex idea.B. Open education is better than traditional education.C. Teachers dislike open education.D. The writer thinks that open education is a good idea in practice.DHOUSTON (AP) --- A 10-year-old boy fatally shot his father Friday, striking him several times as he sat in the front seat of a SUV to pick up the boy from his mother's home for a weekend visit.The incident happened about 3pm on a cul-de-sac（死胡同）in the 1700 block of Cedar Cove Court, said Sgt.

AA girl became a volunteer in the activities of Deathbed Care, which meant visiting and taking care of a patient suffering from an incurable disease with days numbered.The girl was assigned to look after an old man suffering from cancer whose children lived abroad. Their living conditions were not satisfactory while the old man had a lot of savings. She was expected to comfort him and keep up his spirits.Every Saturday the girl came on time to keep him company, telling him stories. When he was having an intravenous drip (静脉滴注), she would help massage his arms. The doctor found the patient much improved mentally. The old man began to involve himself actively in the medical treatment and he seldom shouted at others.But something that happened made the doctor uneasy and puzzled. Each time the girl left, the old man would give her some money. The doctor did nothing to interfere, unwilling to offend the old man. A month later the old man showed evident signs of decline after suffering coma (昏迷) a few times.When rescued from the latest coma, the old man told the doctor his last wish, ―I have deep sympathy for the girl. Will you be kind enough to help her finish her studies？‖But the doctor knew that her family was well off and she had no difficulty pursuing her stud ies. Sometimes she even came to the hospital in her father’s car.When the girl came at the weekend after the death of the old man, the doctor told her the bad news. She was very sad and burst into tears. Then she handed $ 500 to the doctor, saying, ―T he old man had all along thought I came to do the job because of poverty. He gave me money so that I could continue my schooling.‖Now he got the answer to the puzzle. In the last period of his life,the old man found it a real pleasure to be able to help a girl badly in need.1. If you’re a volunteer in the activities of Deathbed Care, what kind of people do you have to attend to?A．Patients with a lot of money.B．Patients suffering from cancer.C．Patients without many days left.D．Patients living alone.2. What can we learn from the passage?A．The doctor told the old man the truth.B．The old man’s children were wealthy.C．The girl’s father encouraged her to accept the money.D．The girl didn’t accompany the old man when he died.3. What is the real reason resulting in the old man’s mental improvement?A．The girl’s love and great care.B．The pleasure of helping people in need.C．The doctor’s medical treatmentD．His children’s progress in life.BWe know the famous ones--the Thomas Edisons and the Alexander Graham Bells --but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper (雨刮器) ? Shouldn't we know who they are?Joan Mclean thinks so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she's developed a course on the topic. In addition to learning "who" invented "what" , however, Mclean also likes her students to learn the answers to the "why" and "how" questions. According to Mclean, "When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try. "Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement. "If I had not heard the story of the windshield wiper's invention,"said Tommy Lee, a senior physics major. "I never would have dreamed of turning my bad experience during a rain storm into something so constructive." Lee is currently negotiating to sell his patent to an umbrella producer.So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn't be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever (操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.Today we benefit from countless inventions and innovations. It's hard to imagine driving without Garrett A. Morgan's traffic light. It's equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?4. By mentioning "traffic light" and "windshield wiper", the author indicates that countless inventions are_______.A. beneficial, because their inventors are famousB. beneficial, though their inventors are less famousC. not useful, because their inventors are less famousD. not useful, though their inventors are famous5. Professor Joan McLean's course aims to _____.A. add color and variety to students' campus lifeB. inform students of the windshield wiper's inventionC. carry out the requirements by Mountain UniversityD. prepare students to try their own invention6. Tommy Lee's invention of the unbreakable umbrella was .A. not eventually accepted by the umbrella producerB. inspired by the story behind the windshield wiperC. due to his dream of being caught in a rainstormD. not related to Professor Joan McLean’s lectures7. Which of the following can best serve as the title of this passage?A. How to Help Students to Sell Their Inventions to Producers?B. How to Design a Built —in Device for Cleaning the Window?C. Shouldn’t We Know Who Invented the Windshield Wiper?D. Shouldn’t We Devel op Invention Courses in Universities?CDisease, poverty, hate, love－Charles Dickens’ stories opened his readers eyes to the most important themes of his age. Two hundred years on, his stories still speak volumes across the world, proving that Dickens’ legacy（遗产）was far greater than just ―great-literature‖.February 7 marks the 200th anniversary of the writer’s birthday. To mark this date, BBC writer Alex Hudson listed six things Dickens gave the modern world. Let’s take a look at two of them.A White ChristmasDickens is described as ―the man who invented Christmas‖ — not the religious festival, but the cultural aspects that we associate with the festive season today.In the early 19th century, Christmas was barely worth mentioning, according to critic and writer Leigh Hunt. The committee which ran the Conservative Party even held ordinary business meetings on Christmas Day—unthinkable in the West nowadays, when everyone but the most necessary workers takes at least three days off.Many people believe that Dickens’ popular descriptions of the festive period becam e a blueprint for generations to come. In his classic novel, A Christmas Carol, he not only put forward the idea of snow at Christmas, but also painted a picture of glowing warmth－―home enjoyments, affections and hopes‖.In his biography of Dickens, Peter Ackroyd wrote: ―Dickens can be said to have almost single-handedly created the modern idea of Christmas.‖―Dickens‖ poverty(贫穷)Dickens was one of the first to take an honest look at the underclass and the poor of Victorian London. He helped popularize the term ―red tape‖ to describe situations where people inpower use needless amounts of bureaucracy(官僚作风) in a way that particularly hurts the weaker and poorer members of society.―Dickensian‖ has now become a powerful word for describing an unacceptable level of poverty. In 2009, when the president of the Association of Teachers and Lecturers in the UK wanted to talk about poverty in some areas of Britain, she did not use words li ke ―terrible‖ or ―horrific‖, but rather described it as ―life mirroring the times of Dickens‖.8. The article is mainly about____________A. a brief introduction to Charles DickensB. Charles Dickens’ influence on the worldC. the characters in Charles Dic kens’ storiesD. Charles Dickens’ achievements in literature9. Why is Dickens called ―the man who invented Christmas‖?A. Because he created both religious and culture festival.B. Because all his novels have something to do with Christmas.C. Because one of his novels helped to shape Christmas celebrations.D. Because he was the first man to have proposed celebrating Christmas.10. According to the article, the phrase ―red tape‖ refers to _______.A. rules or procedures that are required to accomplish a taskB. a situation in which poor members of society are hurt.C. conflict between people in power and weaker peopleD. pointlessly time-consuming official procedures11. We can learn from the passage that______.A. Dickensian is widely used to describe the ChristmasB. Charles Dickens’ novels reflect the true life at his ageC. Every person can take three days off for ChristmasD. The theme of Charles Dickens’ stories is about povertyDHybrid cars （混合动力车）are cars that run on petrol and electricity. They have a small standard petrol engine and a battery electric motor to provide electric power.There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example, when going uphill or accelerating. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic light, keeping only the electric engine running.Conventional cars have large engines to deal with driving uphill and accelerating. Hybrid cars have much smaller petrol engines, improved by electric motors when needed, so they use less petrol. Another way t hat fuel consumption is cut by a system of ―regenerative (再生的) braking‖. The electric motor is used to slow down the car, rather than conventional brakes. The energy produced by slowing the car is changed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In conventional cars the energy produced when braking is wasted.In 1928 Ferdinand Porsche built an experimental hybrid car. The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997. However, hybrid cars became available in the USA only in 1999. As they use less fuel, hybrid cars are cheaper to run. There are also many voices in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don’t have to pay on certain roads. In some cities, hybrid cars are allowed to park for free.12. Hybrid cars consume less energy than conventional cars because hybrid cars .A. have large engines to deal with acceleratingB. have conventional brakes to slow down the carC. have electric power to assist when neededD. have no energy consumption when stopping13. In regenerative braking, .A. energy wasted in conventional cars is stored in the batteryB. the conventional brakes are used to slow down the carC. the battery charges itself when the car is acceleratingD. the petrol engine is usually turned off automatically14. From the last paragraph we can learn that Hybrid cars .A. were first available in the USAB. will gain more popularityC. free their owners from taxD. are free to park anywhere in the city15. The main purpose of this text is to .A. show how hybrid cars slow downB. encourage people to buy hybrid carsC. inform people of a kind of energy-saving carsD. explain why hybrid cars use less energy第二节（共5小题；每小题2分，满分10 分）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。
