Grammar and VocabularySection ADirections: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.Ten year-old Annemarie Johansen lives with her family in Copenhagen, Denmark. There are soldiers on the streets, and the country (21) ______ (occupy) by the Nazis. There isn't enough to eat, and the world is at war. Then the Nazis decide to"relocate"the country's Jewish population. The Danes don't know (22) ______ their friends and neighbors are being taken away. They don't know where they are going, either. But they do know that it is wrong and dangerous and that they must help.Number the Stars is a very powerful novel. During World War II, the Nazis (23) ______ (kill) millions of people in Europe. Many of those people were Jewish. But in Denmark, almost all of the Jewish population was saved. Number the Stars is a work of fiction, but it tells the true story of the Jewish (24) ______ (rescue) during the war. The moving plot is driven by justice, danger and excitement. But the book also deals with significant ideas that are much (25) ______ (big) than the story itself.Annemarie must learn that evil doesn't just appear in fairy tales. It's a real thing that affects real people. She must also struggle with questions of loyalty and sacrifice. Who would she die to protect? And is she brave enough (26) ______ (make) that sacrifice? Most importantly, Annemarie learns that (27) ______ (be) brave doesn't mean being fearless. It means doing the right thing despite the fact (28) ______ you are afraid. That's heavy stuff for a children's novel.I have taught Number the Stars to many classes at many different levels. It has always been a popular choice. It uses simple language and sentences. It is easy to read and provides clear examples of literary techniques like foreshadowing(预示). But it is also interesting, and the characters are (29) ______ (engage) . The plot is full of tension.Lois Lowry, the author, has written many award-winning novels for young people. Number the Stars is a remarkable example of the talent (30) ______ has made her so celebrated.Section BDirections:After reading the passage below, fill in each blank with a proper word given in the box. Each word can be used only once. Note that there is one more word than you need.A. commonB. votingC. effortsD. electedE. endF. protestingG. sayH. exercisedI. arguedJ. equalK. rightsIn most democracies today, people expect women to vote. Women are just as able to make decisions about their 31 leaders as men. But 200 years ago, most people didn't think so.As late as the middle of the 19th century only men voted in most Western countries. A few countries or states let women vote in local elections. But women voting was far from 32 . At that time, people believed that women belonged in the home. That meant they should not get involved with public life.But women in Europe, North America and New Zealand began 33 this situation. They believed that they should have a(n) 34 in their government's leaders. In 1792 an English novelist named Mary Wollstonecraft 35 that women should be able to vote. In the United States, Lucretia Mott and Elizabeth Cady Stanton were important figures. They met whilecampaigning to put a(n) 36 to slavery. In the process, they decided that women also should have more 37 .Yet despite the 38 of these women neither Great Britain nor the United States was the first country to let women vote. That honor goes to New Zealand, which changed their law on September 19, 1893. This was because of women like Kate Shepherd. She led a group that presented petitions（请愿书）to their parliament three years in a row. Shepherd is now honored on New Zealand's $10 bill.New Zealand was followed by Australia in 1902 and Finland in 1906. By this time, some U.S. states and territories allowed women to vote. But the country as a whole didn't give women the right until after World War I.In many countries, the right to hold political office came along with the right to vote. And women have 39 that right. In many countries, women have even held their country's highest office. All of that is due to the efforts of the women who fought for a(n) 40 voice.III. Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.The search for new, clean energy sources has occupied the attention of scientists and politicians for years. One common 41 for green energy is the wind. A new twist on this old resource could cause the energy output of wind-power plants to increase greatly.Standard wind-power plants rely on strong support and 42 can only reach a height of 200 meters or so. Higher than that, winds tend to be stronger and steadier, but the challenge is 43 how to obtain the energy from those winds.Delft University of Technology in the Netherlands and Karlsruhe University of Applied Sciences in Germany have formed a kite-power research group. The group is working to develop kites with inflatable（可充气的）wings 44 to electrical generators (发电机) on the ground.The research group's goal is to design a kite that can operate on its own for 24 hours. Research has begun, but many challenges remain, including making the generators more 45 and perfecting the automatic flight control and the structure of the kites. Nevertheless in June 2012, they demonstrated that their kites could operate 46 at an altitude of up to 700 meters.Meanwhile, in Italy, researchers are working on a(n) 47 power generator that relies on kites when the generator called KiteGen, senses the wind blowing, kites are 48 from the ends of poles with high-resistance cables to control their height and angle. These cables are able to move the kites if the system senses coming objects 49 planes, helicopters or even individual birds. The kites themselves are light, tough and able to reach fairly high altitudes. They loop（绕行）around in the wind, which sets the center of the generator in motion, 50 electric current.KiteGen has the 51 to be very cost-effective in the long run. After the original cost of designing and setting up the plant, little 52 investment will be necessary, apart from standard maintenance. The plant also requires 53 little space, which makes it ideal for cities and means that multiple plants can be set up to provide even more 54 .Kite power has the potential to greatly 55 on current wind-power strategies. In thefuture, it may be an efficient, cost-effective supplement to the other sources of energy we use, or even a replacement for some of them.41.A.resolution B.proposal C.resource D.substitute42.A.generally B.frequently C.continually D.regularly43.A.carrying out B.figuring out C.breaking out D.picking out44.A.chosen B.applied C.collected D.connected45.A.efficient plete C.powerful D.positive46.A.actively B.passively C.automatically D.artificially47.A.strange B.similar C.different D.original48.A.fastened B.revealed C.tailored D.released49.A.except for B.instead of C.such as D.due to50.A.producing B.inventing C.promoting D.developing51.A.qualification B.potential C.trend D.intention52.A.normal B.formal C.additional D.alternate53.A.concretely B.abstractly C.thoroughly D.relatively54.A.energy B.strength C.technology D.opportunity55.A.focus B.extend C.improve D.transferSection BDirections:Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Many people experience problems with their spine(脊椎) as they age. The tissue that protects the joints in the spine gradually breaks down. As a consequence, the bones in the spine begin to rub against each other. This further harms the tissue as well as the bones. The result is pain in the joints and, sometimes, in nerves near the spine.This painful problem is actually a disease called osteoporosis. Some people are more at risk of osteoporosis because of genes that they inherited from their ancestors. Extremely heavy people are also more likely to suffer from this disease because their extra weight puts much pressure on their joints. Fortunately, there are steps that people can take to help prevent osteoporosis from developing in their spine.The most important step is exercise. Stretches can help the muscles around the spine relax and allow bones to shift into better alignment(排列). Strength exercises with light weights or body weight exercises like pushups can also help by strengthening the muscles around the spine. However, people should not overdo these exercises, as repeated motions can strain the muscles around the spine. Trying to lift heavy weights with poor technique can have the same effect.Another important factor is diet. It affects the health of the spine because many vitamins are necessary for bones and nerves. These include B vitamins and omega-3 fatty acids, all of whichhelp keep nerves healthy. People can get more B vitamins and omega 3 fatty acids by taking supplements sold by stores. Another important factor is vitamin D, which is essential for strong bones. All of these vitamins and acids can be obtained from foods. Thus, people can help themselves by including them in their daily diets.56. What does this article mainly explain?A. Various aspects of a medical conditionB. The actions of viruses that cause illnessesC. Drugs often used to solve physical issuesD. The location of organs in the human body57. How does the writer begin this article?A. By predicting improvementB. By analyzing a series of dataC. By introducing minor injuriesD. By describing a gradual process58. What can readers find in this article?A. A warning about working out too hardB. A method for improving sleep qualityC. A slogan used to promote health classesD. A big criticism often aimed at doctors59.What does the article imply about supplement?A. They are mainly for youngsters.B. They are commercial products.C. They are now being researched.D. They are seldom truly effective.(B)In late March of 2018, a tear in the earth about 15meters wide and 20 meters deep suddenly appeared inKenya. It cut across roads and even split houses in two.This crack appeared out of nowhere after heavy rainsand an increase in seismic(地震的) activity. Somescientists believe that it's further proof that Africa isslowly splitting apart.Once, a very long time ago, Africa and SouthAmerica were one landmass before they separated.Similarly, one day in the very distant future, a largepart of East Africa will split off from the rest of thecontinent. This will create a new landmass and a newocean. The breakup is a result of plate tectonics (板块运动), the gradual motion of different parts of theEarth's crust.When plates of the Earth separate and tear away from each other, it is called rifting. The result is a rift valley. Scientists don't understand the exact mechanism behind rifting, but the results are easy to observe in the East African Rift System( EARS). That's why studying this part of the world is so important.The East African Rift System begins in the north in Ethiopia, where three plates are movingaway from each other. Two of them are continental plates, the African and Arabian plates. They are tectonic plates that have a large landmass above water. The third is the Somali plate, considered a minor plate, which is steadily moving away from the other two. But don't plan on visiting the new ocean anytime soon. The plates are moving at a rate of about 6 millimeters a year. At that speed, millions of years will pass before a new ocean is formed.EARS is not all bad news for Kenya. A rift valley is composed of an area where there is increased volcanic activity and thinned planetary crust. This makes it easier to take advantage of the power of steam. For Kenya, this might be an answer to the country's electrical problems. The drought conditions that frequently occur there make it difficult to produce energy. But the geothermal (地热的) power plants going online in 2019 will allow them to produce clean energy with very little water.60.What can be concluded from the passage?A.A war will certainly break out in Africa.B.A disaster will suddenly strike Africa.C.A geological structure will change in Africa.D.A new country will come into being in Africa.61.Which of the following plates might be surrounded by water according to the passage?A.East Africa.B. Somali plate.C. Arabian plate.D. Africa plate.62.What problem may be solved in Kenya thanks to the cracking?A.Poverty.B. Economy.C. Drought.D. Energy.(C)Are you worried about money? If so, I have some good news for you. Someone once said, "If all your problems can be solved with money, then you don't have any. "I get the point. Unless you are on the edge of losing everything and living in your car (which is a very sad thing that happens to people every day), your perceptions of your problems may not be serving you well.Let's take a look. Can you pay your living expenses and support your family? If so, you are OK. Even if you are a family that just barely breaks even every month, you have to count that as a blessing. Most of us also have those terrible, surprising unexpected bills. But unless you lose your job or your mind, don't you always find a way to take care of those expenses?PERTINENT（切中要害的）QUESTIONSTo see if you worry too much about finances, ask yourself a couple of questions. Do you wake up worried about money? Do you check your bank balance and look at upcoming bills more than once every few days or even multiple times a day? If so, then you may have a little financial insecurity going on. Let's look at getting it under control. If it's making you crazy, it can make your family a little crazy too. This type of anxiousness is passed on to others, which is important to remember whenever you have the urge to share your fears.TOO MUCH INFORMATIONTMI (too much information) happens because it seems that by releasing pent-up（压抑的）feelings of anxiety you will feel better and hopefully more supported. And this can happen, but not with your loved ones because they will take on your fear and magnify it. Talk instead with yourfinancial advisor, your bank manager or your therapist. Laying your financial fears at the feet of your family is not good for them or for you. Yes, be honest about any problems, but if you get emotional, so will those closest to you.POSITIVE ACTIONIt's hard to be dispassionate about money, but honestly, it's really the best way to get this issue solved. You have to look at it from a practical standpoint. Go over your debts, look closely at your assets and determine the best thing for you to do with your time right now.Maybe you need to use this time to get your books in order on your computer or use it to job hunt or to promote your business. Then again, you may need to hire an accountant and go on some interviews. The point is simple: the only way to relieve yourself of the uncomfortable feeling of financial pressure is to take some kind of positive action.63.Which of the following is true according to the passage?A.Financial problems are not vital ones in everyone's daily life.B.You'd better calm down when you have financial problems.C.You needn't worry about unexpected bills even if you're out of work.D.When you have financial fears, remember to share feelings with others.64.The passage implies that ______.A.the best way to deal with money problem is to take positive actionB.as long as we share feelings with others, money fear will disappearC.we should have an optimistic attitude toward financial fearsD.any problem we meet can be solved with the help of money65.The phrase lay your financial fears at the feet of your family in the sixth paragraphprobably means ______.A.to solve financial fears caused by your familyB.to help your family smartly avoid financial fearsC.to make your family responsible for financial fearsD.to encourage your family to face financial fears bravely.66.The best title of the passage is ______.A.Perceptions of money and valueB. Passion, money and familyC. Keeping balance of psychologyD. Dealing with money worriesSection CDirections: Complete the following passage by using the sentences in the box. Each sentence can only be used once. Note that there are two sentences more than you need.A.Other people experience false guilt because of high expectations for themselves.B.It's possible that you feel guilty because you actually did something wrong.C.Others try to cover up their guilt by blaming others or becoming angry.D.It can also motivate people to avoid making similar mistakes later.E.In this case, it's important to remind yourself that you have limits.F.Moreover, guilt can result in physical and mental discomforts meanwhile.Guilt is one of the most painful emotions that humans experience but also one of the most common. Nobody enjoys feeling guilty, but this emotion serves an important purpose: It alerts aperson when he or she has done something wrong. This enables the person to make amends and work to heal relationships that were damaged by their actions. 67Nevertheless, guilt can be destructive if it is not dealt with in the right way. It can cause people to avoid others because they are too embarrassed to apologize for their actions or inaction. Some try to avoid the pain of guilt by turning to other worse habits. 68 The proper response to guilt depends on what kind of guilt you're dealing with. For false guilt, it's important to recognize that the guilt does not reflect an actual ethical failure.For example, some false guilt focuses on falling to meet expectations you had for yourself.69 No one is perfect, and no one can do everything, so admitting your limits is actually a sign of humility.It's also important to acknowledge what you are feeling. Even when you don't need to feel guilty, these feelings are real and normal. Try to balance them with positive thoughts, but realize that it often takes time for feelings to change.70 If so, don't try to conceal it. Apologize and ask for forgiveness. Learn from your mistakes, and try to avoid committing the same acts again. Getting on well with the person you hurt should make your guilty feelings fade.Guilt is painful, but it can serve a good purpose if you use it well.IV. Summary Writing71. Directions:Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Have you ever been involved in an animal rescue? This is what happened to Winter the dolphin. Winter was found off the coast of Florida in December of 2005. She was just a few months old, alone, and caught in a crab trap. The ropes from the trap were wrapped tightly around her body.The fisherman who found her called for help, and a rescue team soon arrived. The ropes had cut off the blood circulation to her tail. She was badly hurt. Her rescuers didn't think she would survive. Hoping for a miracle and racing against time to save her, the rescuers transferred her to the Clearwater Marine Aquarium in Florida.The doctors managed to save Winter, but sadly, not her tail. Her tail flukes were too damaged and had to be removed so Winter could live.The little dolphin Winter survived against all odds, but she would never be able to swim normally without a tail. Thankfully the story doesn't end here. Winter was able to swim, but not very well. Because she didn't have a tail, she moved her body in a side-to-side motion like a shark. But the doctors at the aquarium were worried that the unconventional movement would hurt her spine.Kevin Carroll heard Winter's story and thought he could help. He is a specialist who designs and provides prostheses (义肢) for people. If he could help people, why not help a dolphin? He started working with Winter and came up with a solution for a new fluke and tail section.Kevin designed a stretchy sleeve to fit Winter's body and protect her skin. Then a tail made of silicone and plastic was made to tightly fit over the sleeve. Now Winter can swim like otherdolphins. And, she is a great inspiration to people who struggle with their own injuries.V. TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72.交友时勿以貌取人。

宋代科学技术不仅达到中国历史以来的顶峰，也处于当时世界领先地位，如活字印刷术方便了思想的传播，指南针应用于航海，火药使用于军事等，其中也包括造船业的空前发展。

宋代经济重心南移，南方经济和海上贸易空前繁荣，这一经济格局的重大变化成为推动造船业发展的基本动力。

在这一背景下，国家力量和商业力量也对造船业的兴盛产生了重要作用。

中国古代专制政体、科举制度、儒道哲学和思维方式等常被学界视为束缚科技发展的因素。

但如同英国科学技术史专家李约瑟所言，“中央集权的封建官僚式社会秩序在早期阶段是有利于应用科学发展的”，中国古代官僚制度的精神气质以许多方式帮助了应用科学，如激励发明就是中央集权官僚机构的做法。

宋代造船，不论是船舶数量的剧增，还是核心技术的创新和推广，国家都扮演了重要角色。

为了适应大规模的漕船和战船制造需要，宋代使用了船模放样技术，即将规定的船舶制成船样，发放各船场依样放大制造。

这只有在官府统一管理的高度组织化的船场系统中才能有效推行。

公元984年，乔维岳主持制造了中国第一座运河水闸；之后，宋朝在淮南运河和浙西运河逐步推行改堰为闸，大大提高了运河的通航能力。

船闸的修造和运行成本很高，而且需要严格管理的维护人员和启闭制度，靠民间力量难以完成。

另外，船坞为大中型船只维修提供了方便，而船坞造价高昂，非官府不能营办。

国家力量在造船技术的推广应用方面也起着重要作用，南宋车船就是一例。

君子的社会作用，首先是引领社会风气。

“君子之德风，小人之德草，草上之风，必偃”，就是说君子的德行就像一阵风一样，小人的品德就像草一样，风往哪儿吹，草就往哪儿倒。

引领社会，君子，是社会正能量的体现。

宋代的张载在《正蒙》里面也说，“君子于民，导始为德而禁其为非”，就是说，君子引导民众按照社会的德行前进。

引领就必须，君子能够言传身教,所以说“君子不出家而成教于国”,君子不用出门就可以使国家的百姓受到教育,就因为他___________,作出榜样,以自己的行为教育大家。

以儒、释、道为主体要素构成的中华优秀传统文化，源远流长、深邃睿智，集中体现了中华民族的哲学智慧。

中华优秀传统文化蕴含着主体人格意识下的积极入世、主体价值追求下的批判自省、主客体和谐关系下的大同情怀等哲学性格，深刻地凸显出中华优秀传统文化是中华民族独特的性格气节所在、精神魂魄所系，是中华民族的精神家园，是人类文明的生存智慧。

传统哲学对主体的尊重和认知，深刻反映在中华优秀传统文化对主体人格的实现上。

主体的人格性，必然表现为主体对自身存在意义的主动追问，对主体功能发挥的自觉追求。

比如儒家的“内圣外王”“为天地立心，为生民立命，为往圣继绝学，为万世开太平”“圣人与我同类”“人皆可以为尧舜”“知行合一”等等，都是这种主体人格的集中体现。

经世致用的圣贤人格，为几千年来的中国人树立了一种理想人格模型。

这种理想状态或许很难达致，却可以不断追求。

这种追求，体现在哲学上就是主体人格意识的不断觉醒的过程，体现在实践中则是进取精神在积极入世中高扬的过程，进而最终实现主体人格的动态完善和社会的不断发展。

传统哲学的认知意识体现在传统文化中是深厚的自省自律和强烈的批判精神。

孔子的“内省不疚，夫何忧何惧”，曾子的“吾日三省吾身”，孟子的“自反”“反求诸己”，庄子的“至人无己，神人无功，圣人无名”等等，都是儒道对自我本体的认知和探求，这种探求进而体现为对行为和规范的自省，对品德与学识的自觉。
