（每小题 2 分，满分40 分）AMarch 5 is Lei Feng Day. People are encouraged to help others and to learn from Lei Feng. This year, my school student union went to one of our city’s tourist sites to help clean it up.We finished our work, took photos and chatted with street vendors ( 小商贩) about their lives. One old lady said she remembered how all students used to go out into the streets and do voluntary work. Another told us that when she was small,she and her friends would do a lot of simple but practical things to help others. They would help old ladies carry things or fix broken chairs at school.“But things have changed over the years. The younger generation doesn’t really understand the spirit of Lei Feng,” an old man said, “Young people simply do what they are told at school. They do ‘good deeds’ because they are told to and take photos to put on the school website.”His words made me think. We had been told to do things to hep people on Lei Feng Day. But none of that love and care came from our own hearts. None of it was sincere. What should matter most are our good intentions and the ability to follow them through.We should believe that every one of us can make a difference. Good will means holding out a helping hand to people whenever possible, even if we can only make a small difference. We shouldn’t need cameras or praise to make us do good things. We can only pass on the spirit of Lei Feng if we actually feel that spirit inside ourselves.26.The student union went to the tourist site to .A.go sightseeingB.help do some cleaningC.clear away the vendorsD.chat with the vendors27.After work, the students and the vendors talked about .A.the hard life of all the vendorsB.the experience of helping othersC.the skills of making clothesD.the rewards of the job28.Which of the following is NOT an example of how “things have changed over the years”?A.Young people don’t understand the spirit of Lei Feng.B.Students just follow the requirements of the school.C.Doing a good deed has become a kind of show on the website.D.Helping others is no longer important.29.The underlined word “them” refers to according to the passage.A. our own heartsB. some thingsC. his wordsD. our good intentions30.How can we learn from Lei Feng, according to the writer?A.Do what your school tells you to do.B.Talk sincerely with the vendors.C.Always help others in need.D.Only do something more once you are praised.BOne Sunday morning, I was unhappy. Two of my friends went to the movies the day before, but they didn’t invite me. I was in my room thinking of ways to make them sorry when my father came in and asked, “Want to go for a ride today Judy?”“No! Leave me alone!” Those were the last words I said to him that morning.My friends invited me to go swimming with them a few hours later. I forgot to be angry with them and went. When Icame back home, I saw a note (便条), “Dad has an accident. Go to Highland Park Hospital. Mom.”As soon as I reached the hospital, my mother held my hand and said, “Luckily, your dad was able to tell others to leave him alone and just call 911! If they had moved him...” My mother talked a lot, but I only remembered: LEAVE HIME ALONE.Weeks later, my father was able to talk. One day, I said sorry to him for what I said that Sunday morning. He smiled and said he remembered nothing but saying goodnight to me the night before.I knew he was lying. I regretted my thoughtless words. I never really wanted him to leave me alone. It was too terrible to imagine.Words do have great power. They can hurt or they can heal (治愈). And we all have the power to choose our words.31.What did Judy’s father ask her to do that Sunday morning?A. To go for a ride.B. To go swimming.C. To go to the movies.D.

She did not know how she was going to make it and wanted to give up. She was tired of fighting and struggling. It seemed as one problem was solved a new one arose.Her father, a cook, took her to the kitchen. He filled three pots with water and placed each on a high fire. In one he placed carrots, in the second he placed eggs, and in the last he placed coffee beans. He led them boil, without saying a word.The daughter had no idea what he was trying to do. Half an hour later, he turned down the fire and placed the carrots, eggs and the coffee into different bowls. He asked his daughter, “Darling, what do you see?”“Carrots, eggs, and coffee,” she replied.He brought her closer and asked her to feel the carrots. She did and noticed that they were soft. He then asked her to take an egg and break it. After pulling off the shell, she watched the hard-boiled egg. Finally, he asked her to taste the coffee.The daughter enjoyed the taste of coffee and smiled.She asked, “What does it mean. Father?”He explained, “Each of them had faced the same situation, 212 degrees of boiling water. However, they had different results. The carrots went in strong and hard. But after going through boiling water, they became soft and weak. She asked. The inside of the egg became hardened in the boiling water. It was also changed by the water like the carrots. However, the coffee beans are the most powerful. After they were in the boiling water, they turned the water into tasty coffee.“Which are you?” he asked his daughter. “When adversity (逆境) knocks on your door, how do you respond (反应)? Are you a carrot, an egg, or a coffee bean?36.Why did the daughter go to her father?A.She wanted to eat something.B.She caused a problem.C.She had some troubles with her life.D.She complained to her father.37.What does the underlined word “arose” mean in Paragraph 1?A.

Carrots, Eggs and Coffee BeansDHave you ever experienced the feeling of falling as you start to fall asleep? Sometimes you may wake up to this feeling. If so, don’t worry. Many people have felt the same thing.In fact, the muscle twitches (肌肉抽搐) in the arms, legs or other parts of the body are called hypnic jerks (入睡抽动) or sleep starts. And they are very common. Up to 70 percent of people experience them sometimes, Huffington Post reported. But what causes it?There are some theories. Some scientists believe that the feeling of falling comes from the body relaxing itself, especially if the person is anxious or unable to get comfortable. As you’re about to sleep, your m uscles become relaxed. But your brain stays awake. It misunderstands the relaxing of your muscles as a sign that you’re falling. Then the brain jerks th e body awake as if it’s trying to protect you.Other scientists believe that different phases of sleep might cause the hypnic jerks. When we sleep, we experience two phases: non-rapid eye movement (NREM, 非快速眼动睡眠期) and rapid eye movement (REM, 快速眼动睡眠期). During REM, our heart rate, breathing and nervous system can act irregularly. If the body experiences flashes ( 一瞬间) of REM while entering sleep, these irregularities could cause twitches.If you don’t want to experience hypnic jerks, scientists have some suggestions. When you become deeply relaxed, you can learn how to reconnect (再联系) slowly by moving your fingers and toes a little bit. Then start to move your head and open your eyes, while being aware of yourself as you get out of the relaxed state.But experts agree that hypnic jerks, though sometimes scary, are harmless. If it wakes you up, simply roll over and go back to sleep. But keep in mind: a caffeinated (含咖啡因的) drink, exciting evening activities or stress may make hypnic jerks happen more often.41.of people don’t experience hypnic jerks.A. About 30 percentB. About 40 percentC. 60 percentD. 70 percent42.The third paragraph mainly tells us .A.there are all kinds of theories about hypnic jerksB.People sometimes get anxious or uncomfortableC.different phases of sleep might cause hypnic jerksD.the feeling of falling comes from the body relaxing itself43.How many theories on what causes hypnic jerks are mentioned?A. TwoB. FourC. ThreeD. Five43. Which of the following can make hypnic jerks happen more often?①Drinking caffeinated drink ③Too much stress ②Singing songs for a long time before sleep ④Reading a book quietlyA. ①②③45.What’s the best title?B. ②③④C. ①②④D. ①③④A.How to Experience Hypnic JerksB.Feelings of Falling While Going to SleepC.What Causes Hypnic JerksD.Sleeping Is Good for Our Health第二节阅读下面短文，从短文后所给的五个选项中选出能填入短文空白处的最佳选项，使短文通顺、连贯，意思完整。

Left in poor conditions with no food or water, they have little hope as they live out their days without the mercy they deserve. Some are found and rescued, given the chance to experience how great life and humans can be; others aren't so lucky. To grow as a nation, we must fight for these abused(受虐待的) animals’ rights and seriously punish heartless owners.One of the first steps in protecting animals and creating effective cruelty laws is to know what animal cruelty actually is. There are two categories: passive cruelty and active cruelty. The first involves acts of omission, meaning the abuse happens as a result of ignorance or lack of action. Passive cruelty might seem less serious, but that is not the case; it can lead to terrible pain and suffering, and finally death. Examples include starvation, inadequate shelter in extreme weather conditions, and the failure to get medical care. Passive cruelty is sometimes due to the owner's ignorance, so many animal control officers will first try to educate ignorant owners on how to properly care for animals before giving them a citation(传票) or putting them in prison.Active cruelty, on the other hand, is more well-known and disturbing. Sometimes referred to as non-accidental injury, this type of abuse involves purposeful harm on an animal in order to feel more powerful or gain control. Active cruelty against animals should be taken very seriously, since it can be a sign that a person hasserious psychological issues and may commit more acts of violence---possibly against humans.It is hard to tell just what drives people to harm innocent animals. Most animal abusers find some sort of achievement or power in torturing a victim that they know can't fight back. While not all animal abusers become serial killers, it is important to take every case seriously.As a nation we need to make it our right to come together and ensure the safety of our beloved pets. As Margaret Mead once said, “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.”4. What is the first step to do with the passive cruelty abusers?A. To throw them into prison.B. To bring the case to the court.C. To teach them how to treat animals.D. To give them a strong warning.5. We can learn from Para.3 that active cruelty ______.A. is actually a sign of power or controlB. has been taken seriously in the nationC. may lead to serious psychological problemsD. may cause acts of violence against humans6. What is the author’s attitude towards animal cruelty?A. Uncertain.B. Doubtful.C. Concerned.D. Pessimistic.7. The author wrote this passage to ______.A. warn those heartless pet ownersB. tell people the harm of animal crueltyC. explain the reasons why people harm animalsD. call on people to fight for the abused animalsCYou must have read "The Tortoise and the Hare(《龟兔赛跑》)" when you were younger. So which animal are you? The tortoise or the hare? Do you rush around trying to do things as quickly as possible? Or do you deal your work at a slow , but steady(稳定的)pace? Whether you approach life like the tortoise or the hare can make a difference in the results you'll see.Some will say that you should avoid being like the hare. After all. he was overconfident and finally lost the race. You mayalso have heard teachers say from time to time that "haste makes waste”. But what does that mean?Most people think it meant that the faster you do something,the more likely it is that you'll make mistakes. Many teaches wantyouto approach your schoolwork thoughtfully and carefully.But does haste always make waste? Not necessarily ! Some people are able to work quickly while also maintaining(保持)a high level of quality in all that they do. Recent research, however, is making the idea of haste making waste seem more believableResearchers found that the brain changes into a special mode(模式)when forced to make rapid decisions. Overall, there appears to be a trade-off between speed and correctness. As the brain makes decisions more quickly, those decisions are usually built on less information, which often leads to a greater likelihood of mistakes.When you approach things like the tortoise. you methodically and steadily work towards your goal. You might not arrive there first, but then again you might! In any case, you're likely to make fewer mistakes and you might just enjoy the journey more than the bare.Goals are great to work towards, but often the achievements aren't what we remember. In the end, the most meaningful and important parts of our lives are the journeys we went on , not the destination we reached. So be the hare when you have to, but always remember that the slow and steady journey is what you’ll remember and treasure the most.8. Why does the author mention the story in the first paragraph?A. To introduce the topic.B. To show its popularity.C. To suggest its importance.D. To advise readers to read it.9. For what purpose do teachers often say “haste makes waste to students?A. To ask them not to waste their time.B. To tell them it is OK to make mistakes.C. To ask them to avoid making silly mistakes.D. To tell them they should check their schoolwork.10. What is Paragraph 4 mainly about?A. How the brain collects the information it needs.B. When the decision made by the brain is correct.C. Why the quickly-made decision is often unwise.D. What the relationship between lime and results is.11. Which of the following may the author agree with?A. Finishing the race is often a victory for everyone.B. Joy is found not in finishing an activity but in doing it.C. The journey to every destination starts with a small step.D. A destination is important because it guides us on the journey.DSome years ago a young man applied to a large United States optical firm for a job as a lens designer. He apologized for lack of training, but on announcing that he owned two copies of the classic Conrady's Applied Optics and Optical Design, one for his office and a second for his bedside table, he was hired on the spot. Perhaps the story will be repeated some day with Buchdahl's Introduction to Hamiltonian Optics as a similar certificate of qualification.Hamiltonian theory describes with powerful generality the overall properties of optical systems considered as ‘black boxes’, although it does not describe the detailed structure needed to construct the systems and achieve these properties. Buchdahl's book is therefore on the subject of geometrical optics, but it is not about how to design lenses. It is, however a compact comprehensive account of the fundamentals of the theory written with the lens designer's needs very much in mind. Every lens designer worth his salt has at some time in his career attempted to apply the broad concepts of Hamiltonian optics to the solutions of practical problems. Success has been sufficiently rare that the theory, as such, has made little direct contribution to techniques for optical instrument design. The failures have been frustrating because of the obvious fundamental power of the theory and because of its conceptual elegance. The indirect effects have been large, however, both in contributing to an understanding of fundamental principles that govern the overall behavior of optical systems and in pointing the way to other, more practical, theoretical approaches.Buchdahl approaches the subject not only as a capable mathematical physicist, but as one who with a knowledge of practical optics has made a significant contribution to geometrical optical theory. Buchdahl's approach has, over the last decade, had a major impact on modern lens design with computers. Thus, he brings to this exposition of Hamiltonian optics a familiarity with practical optics not usually found in authors on this subject.The author claims his book to be non-mathematical, and indeed it might be so viewed by a professional mathematician. From the point of view of many physicists and engineers, it will appear to be quite mathematical. Moreover, this is a tightly written book. The subject matter is developed with precision, and the author expects the reader, at very point, to be master of the preceding exposition.12. Hamiltonian theory met with failures as a result of ______.A. newer finding related to the wave particle nature of lightB. very complicated concepts too difficult to understand by most lens designersC. too much mathematical detail in the theoryD. not enough practical information offered by the theory to allow for use by lens crafters13. The author of this passage implies that Introduction to Hamiltonian Optics is necessary to ______.A. the students who are major in mathematical geometryB. those who want to grasp the basic principles of optical systemsC. the lens designers who look for instructions on practical designsD. those who are interested in physics14. The article points out that the great benefits of Hamiltonian optics have been found is ______.A. indirect ways of learning mathematicsB. a fundamental power within the theoryC. the conceptual elegance of the theoryD. the practical applications of the theory in finding new approaches to old problems15. This passage is probably excerpted from ______.A. a review of a bookB. a chemistry textbookC. an optician's essayD. a general science text第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

（24分，7—12每题2分）勾践自会稽归七年，拊循其士民，欲用以报吴。
大夫逄同谏曰：“今夫吴兵加齐、晋，怨深于楚﹑越，名高天下，实害周室，德少而功多，必淫自矜。
为越计，莫若结齐，亲楚，附晋，以厚吴。
吴之志广，必轻战。
是我连其权，三国伐之，越承其弊，可克也。
”勾践曰：“善。
”其后四年。
吴士民罢弊，轻锐尽死于齐﹑晋。

今君王举玉趾而诛孤臣，孤臣惟命是听，意者亦欲如会稽之赦孤臣之罪乎？”勾践不忍，欲许之。
范蠡曰：“会稽之事，天以越赐吴，吴不取。
今天以吴赐越，越其可逆天乎？且夫君王蚤朝晏罢，非为吴邪？谋之二十二年，一旦而弃之，可乎？且夫天与弗取，反受其咎。
君忘会稽之厄乎？”勾践曰：“吾欲听子言，吾不忍其使者。
”范蠡乃鼓进兵，曰：“王已属政于执事，使者去，不者且得罪。
”吴使者泣而去。
