a−22＞a且a+22≥a，即a＜-2时，f（x）在（-∞，a）和（a−22，+∞）单调递增，∵f（x）在（-4，2）上单调递增，∴a≥2或-4，∴a≤-6；③ a−22＞a且a+22＜a，即a＜-2且a＞2时，不存在满足条件的a值；④ a−22＜a且a+22＜a，即a＞2时，f（x）在（-∞，a+22）和（a，+∞）上单调递增，∵f（x）在（-4，2）上单调递增，∴ a+22≥2或a≤-4，∴a＞2综上：a≤-6或a≥-2-----------------------------------------------------（16分）【点评】：本题考查的知识点是分段函数的应用，分类讨论思想，二次函数的图象和性质，难度中档．18.（问答题，0分）一家公司计划生产某种小型产品的月固定成本为1万元，每生产1万件需要再投入2万元，设该公司一个月内生产该小型产品x万件并全部销售完，每万件的销售收入为4-x万元，且每万件国家给予补助2e- 2elnxx - 1x万元．（e为自然对数的底数，e是一个常数）（Ⅰ）写出月利润f（x）（万元）关于月产量x（万件）的函数解析式（Ⅱ）当月产量在[1，2e]万件时，求该公司在生产这种小型产品中所获得的月利润最大值（万元）及此时的月生成量值（万件）．（注：月利润=月销售收入+月国家补助-月总成本）【正确答案】：【解析】：（Ⅰ）由月利润=月销售收入+月国家补助-月总成本，即可列出函数关系式；（2）利用导数判断函数的单调性，进而求出函数的最大值．【解答】：解：（Ⅰ）由于：月利润=月销售收入+月国家补助-月总成本，可得 f (x )=x (4−x +2e −2elnxx −1x −2)−1=−x 2+2(e +1)x −2elnx −2(x ＞0)（Ⅱ）f （x ）=-x 2+2（e+1）x-2elnx-2的定义域为[1，2e]， 且 f′(x )=−2x +2(e +1)−2e x =−2(x−1)(x−e )x(x ＞0) 列表如下：且f （e ）=e 2-2．即：月生产量在[1，2e]万件时，该公司在生产这种小型产品中所获得的月利润最大值为f （e ）=e 2-2，此时的月生产量值为e （万件）．【点评】：本题主要考查利用导数研究函数的单调性、求函数的最值等知识，考查学生利用导数解决实际问题的能力及运算求解能力，属于难题．19.（问答题，0分）（1）用分析法证明：当x≥0，y≥0时， √2y ≥ √x +2y - √x ； （2）证明：对任意x∈R ，3|x-1|-x+1，x 2+x ，-2x-1这3个值至少有一个不小于0．【正确答案】：【解析】：（1）利用分析法的证明方法，推出使命题成立的充分条件 √2xy ≥0 ，即可． （2）利用反证法，假设3|x-1|-x+1，x 2+x ，-2x-1这个3值都小于0，推出3|x-1|+x 2-2x ＜0，得到矛盾的结论，即可证明命题成立．【解答】：解：（1）要证不等式成立，只需证 √x +√2y ≥√x +2y 成立， 即证： (√x +√2y)2≥(√x +2y)2成立， 即证： x +2y +2√2xy ≥x +2y 成立， 即证： √2xy ≥0 成立，因为x≥0，y≥0，所以 √2xy ≥0 ，所以原不等式成立． （2）假设3|x-1|-x+1，x 2+x ，-2x-1这3个值都小于0，即3|x-1|-x+1＜0，x2+x＜0，-2x-1＜0，则3|x-1|+x2-2x＜0，（*）而3|x-1|+x2-2x=3|x-1|+（x-1）2-1≥1+（x-1）2-1≥（x-1）2≥0．这与（*）矛盾，所以假设不成立，即原命题成立．【点评】：本题考查分析法以及反证法的综合应用，考查分析问题解决问题的能力，是中档题．20.（问答题，0分）已知函数f（x）=x2+ax+a+1，g（x）=lnx，（a∈R）．（1）当a=1时，求函数y=f（x）-g（x）的单调区间；（2）若存在与函数f（x），g（x）的图象都相切的直线，求实数a的取值范围．【正确答案】：【解析】：（1）求得函数h（x）的定义域，以及求导数，讨论单调区间，可得．（2）设函数f（x）上点（x1，f（x1））与函数g（x）上点（x2，f（x2））处切线相同，分别求的切线的斜率，可得设14x2−a2x+lnx−a+a24−2 =0，设F（x）= 14x2−a2x+lnx−a+a24−2，求出导数和单调区间，最值，运用单调性，计算可得a的范围．【解答】：解：（1）因为函数f（x）=x2+ax+a+1，g（x）=lnx，所以a=1时，函数h（x）=f（x）-g（x）=x2+x-lnx+2，定义域为（0，+∞），则h′（x）=2x+1- 1x = (2x−1)(x+1)x，x∈（0，+∞），由h′（x）＜0，即(2x−1)(x+1)x ＜0，解得0＜x＜12，由h′（x）＞0，即(2x−1)(x+1)x ＞0，解得x＞12，所以函数h（x）的增区间为（12，+∞），减区间为（0，12），综上所述，结论时：函数y=f（x）-g（x）的增区间为（12，+∞），减区间为（0，12），（2）假设存在函数f（x），g（x）的图象都相切的直线，设函数f（x）上点（x1，f（x1））与函数g（x）上点（x2，f（x2））处切线相同，由已知有：f′（x）=2x+a，g′（x）= 1x，则f′（x1）=g′（x2）= f(x1)−g(x2)x1−x2，即2x1+a= 1x2 = x12+ax1+a+1−lnx2x1−x2，所以x1= 12x2−a2代入1x2=x12+ax1+a+1−lnx2x1−x2，得：1 4x2−a2x2+lnx2−a+a24−2=0，设F（x）= 14x2−a2x+lnx−a+a24−2，则F′（x）=- 12x3+a2x2+1x= 2x2+ax−12x3，x∈（0，+∞），则方程2x2+ax-1=0有一个正根，记为x0（x0＞0），则2x02+ax0-1=0，即a= 1−2x02x0 = 1x0−2x0，当0＜x＜x0时，F′（x）＜0；当x＞x0时，F′（x）＞0，所以F（x）在区间（0，x0）上单调递减，在区间（x0，+∞）上单调递增，故当x=x0时，函数F（x）min=F（x0）=x02+2x0- 1x0+lnx0-2，设G（x）=x2+2x- 1x+lnx-2，则G′（x）=2x+2+ 1x2 + 1x＞0，在区间（0，+∞）上恒成立，所以G（x）在区间（0，+∞）上时增函数又G（1）=0，所以0＜x≤1时，G（x）≤0，即当0＜x1≤1时，F（x1）≤0，又当x=e a+2时，F（e a+2）= 14e2a+4 - a2e a+2+lne a+2-a+ a24−2 = 14（1e a+2−a）2≥0，所以当0＜x1≤1时，函数F（x）必有零点，即当0＜x1≤1时，必存在x2使得① 成立，即存在x1，x2，使得函数f（x）在点（x1，f（x1））与函数g（x）在点（x2，f（x2））处切线相同，又由y= 1x −2x，得y′=- 1x2−2＜0，所以y= 1x−2x在（0，1]上单调递减，故a= 1x0−2x0∈[-1，+∞），综上所述，结论是：实数a的取值范围为[-1，+∞）．【点评】：本题考查切线的斜率，及导数的综合应用，属于难题．。

Until four years ago, Liu worked full-time as a computer engineer at a power plant in Shanxi province. He only wrote science fiction in his spare time. But it was during this time that Liu’s imagination took flight. He did what he might never have the chance to do in real life – wander in space, fight with aliens, and visit planets light-years away.But even with such a powerful imagination, Liu, 55, probably hadn’t expected that he would become the first Asian to win the Hugo Award, science fiction’s highest prize, in 2015. Perhaps neither did he think that former US president Barack Obama would read his novel The Three-Body Problem, nor that on Nov 9 in Washington DC, he would win the 2018 Arthur C．Clarke Award for Imagination in Service to Society. It’s the first time a Chinese writer has ever won the award.In his acceptance speech, Liu said that he owed his imagination to Arthur C．Clarke (1917-2008), a famous UK sci-fi author. He said that reading Clarke’s 1968 classic novel 2001: A Space Odyssey in the early 1980s had a great effect on him.“My mind opened up like never before. I felt like a narrow river finally seeing the sea,” Liu said. “That night, in my eyes, the starry sky was completely different from the past. For the first time in my life, I was awed (使……敬畏) by the mystery of the universe.”But no matter how far away Liu’s imagination takes him, somehow his novels always stay rational.In The Three-Body Problem, for example, Liu tells a tale of aliens invading Earth. But unlike other alien stories, Liu talks more about relationships between civilizations, rules of survival, and the meanings of life. And in The Wandering Earth, Liu looks ahead to the day when our solar system comes to an end and humans have to look for a new place to live. However, all his visions and solutions are based on “hard science”. Liu’s works aren’t simply daydreams.4．What do we know about Liu Cixin?A．He became a full-time writer when he was young.B．He dreamed about wandering in space from childhood.C．He is the first Asian to win the Arthur C．Clarke Award.D．He is the first Chinese winner of the Hugo Award.5．Liu Cixin’s words are used mainly to show ________.A．his interest in mysteries of the universe B．his love of reading science fictionC．his confusion when he started writing D．his feeling after reading Clarke’s work 6．What’s the text mainly about?A．Liu Cixin’s achievements and writing style.B．Liu Cixin’s contributions to science fiction.C．How Liu Cixin became a sci-fi writer.D．How Liu Cixin started a new sci-fi style.Not even the sea is safe from the glare (强光) of humans’ light at night. Researchers published the first global map of ocean light pollution. It shows large parts of the sea are lit up at night. And that risks confusing or disrupting the behaviors of sea life.Tim Smyth led a team to research where in the water this light is strongest. Smyth and his colleagues started with a world map of man-made night-sky brightness that had been created in 2016. Then they added data on the ocean and atmosphere. Some data came from shipboard measurements of man-made light in the water. Others came from satellite images that judge how clear the water is. Particles (微粒) in the water, such as tiny floating plants and animals, can affect how far downward light travels. These factors vary from place to place and may change with the seasons. The team also used computers to copy how different wavelengths of light move through water.Next, they wanted to know how that underwater light might affect animals. Not all species will be easily affected. The team focused on copepods (桡足亚纲甲壳动物). These common creatures are a key part of many ocean food webs. They use light as a signal to move all together to the dark deep, seeking safety from other surface creatures. Normally they use the sun or the winter moon as their signal. Too much man-made light can mess up their usual patterns.Light pollution is strongest in about three feet of the water. Here, man-made light can be strong enough to confuse the copepods. Nearly 2 million square kilometers of ocean get suchstrong night light. That’s an area about the size of Mexico. Farther down, the light gets weaker. But even 65 feet deep, it’s still bright enough to bother copepods across 840,000 square kilometers of ocean.The team described its findings December 13 in Elementa: Science of the Anthropocene. 7．What do we know about copepods from the passage?A．They are main eaters of other creatures.B．They are not affected by underwater light.C．They can escape attacks with the help of light.D．They can weaken the effect of man-made light.8．How does the author show the seriousness of light pollution in Paragraph 4?A．By stating opinions.B．By listing numbers.C．By raising questions.D．By giving reasons.9．Which of the following can is a suitable title for the text?A．Light Pollution from Sea Life B．Living Conditions of CopepodsC．Discoveries of Copepods D．Light Pollution Even in SeaImagine this: you walk into work and the camera above the doors scans your face, opening them automatically without you lifting a finger. Oh, but you need to run to the chemist's at lunch. You walk up to a camera, and your prescription（药方）is deposited in front of you. After work, you look at your face in the mirror, and it reminds you to wear sun-cream the next day. Sounds pretty good, right?Now imagine this: when you are walking down the street, a pair of policemen pull their guns and tell you to drop to the ground. After several days in jail, they let you know you were misidentified as a violent criminal on the loose. Regardless of your innocence, you're in the system. Now wherever you go, cameras that capture you will alert police to watch out for you. Even worse, as you enter stores, the facial recognition system lets the staff know a recently arrested individual has entered the building. Doesn't sound so good?As fantastical as either of those pictures might seem, it's quite possible that this will be the future we're headed towards. The "benefits" of the technology are already being implemented by airlines, as seen by JetBlue Airways. Rather than scanning a boarding pass or handing over a passport, you simply stare into a camera and you're identified. This does save time and make processes the best possible, but it raises the question: do you have the right toyour own face? Who is responsible for the protection of this information? Can I even remove my face from this database and just go the old-fashioned way?We humans have the never-ending need to make things smoother, better and faster. This desire has helped drive the remarkable progress we have achieved as a society. However, it's time to take a step back and ask some necessary questions. We need to discuss whether we actually need the extensive use of facial recognition technology and how to ensure law enforcement (执行) doesn't abuse this technology. If we act now, I believe we can succeed in preventing technology companies from infiltrating（潜入）every aspect of our lives. If we don't, though, I fear the worst.10．What does the underlined word "fantastical" probably mean?A．Unreal.B．Optimistic.C．Reasonable.D．Unbearable. 11．What is the downside of facial recognition technology?A．Inequality of rights.B．Disorder of society.C．Violation of privacy.D．Denial of responsibility.12．What may be to blame for the negative effect of facial recognition technology?A．Improper enforcement of laws.B．People's lack of awareness.C．Ignorance of the technology.D．Companies' pursuit of profit. 13．What is the best title for the text?A．How do we live safely with facial recognition technology?B．Are we prepared for the use of facial recognition technology?C．What will the future be like without facial recognition technology?D．Can we prevent the development of facial recognition technology?Most students do an IQ test early in their school career. Even if they never see their results, they feel that their IQ is what determines how well they are going to do in life. When they see other students doing better than them, they usually believe that those students have a higher IQ and that there is nothing they can do to change facts. However, new research into EQ suggests that success is not simply the result of a high IQ.While your IQ tells you how intelligent you are, your EQ tells you how well you use your intelligence. Professor Salovey suggests that when predicting someone’s future success, their EQ might actually matter more than their IQ. For example, have you ever wondered why some of the smartest students in your class, who you think deserve good grades,sometimes end up failing exams? Perhaps their failure is because of their low EQ.It is generally believed that people with high EQs are open to new ideas and have positive attitudes towards life. They are also less likely to be troubled by problems. On the other hand, there is little doubt that people with low EQs often have problems getting on with other people and dealing with difficult situations; thus they have a harder time surviving in life.The good news is that most social scientists agree that EQ has a lot to do with education. Compared with IQ that seems to be fixed the moment you were born, EQ could be improved with right approaches. Some are trying to study the possibility of improving a person’s EQ, especially when it comes to“people’s skills”, such as understanding and communication.To get ahead in the world and lead a happy successful life means getting on with other people and being able to understand and react to situations in the best way. This requires a high EQ—the higher the better.14．Most students think others’ better performance in studies is due to_____.A．high IQ B．teachers’ assistanceC．good luck D．hard work15．What can we infer from paragraph 2?A．Only EQ determines someone’s future success.B．EQ plays a more important role in one’s future success.C．Some smartest students fail exams because of their low IQ.D．The most intelligent students deserve good grades.16．What will people with a high EQ tend to do?A．Refuse new ideas.B．Be troubled by problems.C．Have a negative attitude.D．Get along well with others.17．What contributes to a higher EQ according to most social scientists?A．Education.B．Parents.C．Friends.D．Environment.二、七选五Would you like to get funding (资金) for a project of your own — maybe a film or helpmake your pitch stand out in a crowd.Start networking. Nothing is more important than to be involved in a community of people with the same interest — whether it’s through articles, videos, or social media. 19 Or join in online discussions connected with your project. When you’ve built a community and kept it up, it’s time to make your pitch.Get emotional (有感染力的). Funders like ideas that make them laugh or think. A lot of campaigns out there are competing for attention. 20 Try it out on family and friends. Not only can they give you advice, but they may also be your first funders.Make a plan. You need to plan how the money will be spent, a timeline and the right crowd funding platform (平台) to make your pitch. Consider how each site calculates (计算、推测）how much to charge. 21Keep your funders involved.Don’t just say thank you — offer rewards. 22 Make sure that your rewards are things you can actually achieve. Funders care about your project — keep them updated, ask their advice, and suggest they tell their friends about your project.A．One way to improve your pitch is to simply watch how others do it.B．To increase traffic for your site, try posting interviews with experts who do projects like yours.C．You should also consider whether projects like yours are successful on the sites.D．Work on a pitch that touches people’s hearts and minds in seconds.E．By doing so, you can get others to support your project.F．We all want someone to accept our ideas and give us the go-ahead.G．They can be as simple as a T-shirt.三、完形填空I was in fifth grade and about to take a science test. Since first grade I had always been good at school. I always did well on tests. When it came to fifth grade science, however, Ithe teacher started to hand out the test papers. I didn’t want to get caught, but I didn’t want to 28 either.As the teacher was starting down my row, suddenly the 29 went off. It was an unscheduled fire drill.

Shea was born with a partial right hand, which restricts her ability to do things that other kids take for granted.“My mom went online”, says Shea, who lives in Muknowango, Wisconsin. Shea’s mother, Ranee, soon learned about a community of artists, designers, and scientists who are making big breakthroughs with artificial hands.Frankie Flood, a professor at the University of Wisconsin in Milwaukee, was among the designers who saw Ranee’s online request. Flood obtained help from fellow professor Adeam Blair and their students, who were learning how to make designs using a 3-D printer. “We made a mold(模子) of Shea’s hand out of plaster(石膏), and then we 3-D scanned her hand,” Flood says.While being fitted in Flood’s laboratory, Shea got to choose the color of her new hand. She went with bright pink. She now has a pink hand, a purple hand, and a purple and pink one, and can do things that she couldn’t do before, like peeling potatoes, picking up objects, and catching a ball.Flood and his team have since built hands for six other local children. Indirectly, they have helped dozens more by posting their designs online so that people around the world can print them out. Flood is also working on artificial legs for military soldiers who were injured on the battlefield. “Without a covering, the artificial leg is kind of ugly and plain,” Flood says. “Soldiers wa nt something that will restore the shape of their legs and make them look cooler when they’re playing sports.”As for Shea, the aspiring musician can now play her violin with the help from an adaptive device that Flood’s team created. “Nothing is ever going to hold her back,” Shea’s father, Steve, told a local reporter.59.What do we know about Shea from Paragraph 1?A. Her left hand is weak.B. She is eager for many gifts.C. She was born with a disability.D. She comes from a poor family.60.What can Shea do with the help of her new hand?A. She can do simple things easily.B. She can play different kinds of sports.C. She can build hands for other children.D. She can make designs using a 3-D printer.61.What can we infer from the passage?A. Flood made S hea’s new hand alone.B. Shea has hands of different colors now.C. Soldiers like artificial legs though they are ugly.D. Ranee made big breakthroughs with artificial hands.62.What do Steve’s words suggest in the last paragraph?A. Shea is a determined girl.B. Shea has an advanced device.C. Shea is a famous musician now.D. Shea gets much help from her family.CPeer PressurePeople who are at your age, like your classmates, are called peers. When they influence you on your decision or action, it’s called peer pressure. All of us, at some point in our lives, have had to deal with peer pressure. The need to follow the crowd and do what majority of us are doing forces us to take up activities which we wouldn’t otherwise.Recent studies have shown that peer pressure might cause an upside to you. It can make you reflect on your actions and make changes to your ways to become a better one. Observing others working hard to reach their goals will definitely encourage you to make a great effort to achieve something positive. When a teen knows that his teammates are practicing hard to become better players then it will directly affect his own performance. He will put in twice the time and energy to raise the level of his game and ensure he has a place on the team.Having a group that brings positive peer pressure can also help you pick up healthy habits that can shape both your personality and your future. The motivation to do well because of pressure from your peers can actually become inspiration. For example, when a child knows that some of his friends regularly read storybooks, he may get into the habit of reading. Seeing that his friends exercise daily, even he may take up the habit and adopt it in life.Just as some influences can be positive, some can be negative too. Peer pressure sometimes can make a dip in your self-confidence. Some kids give in to peer pressure because they want to be liked, or because they worry that others might make fun of them if they don’t go along with the group. Othe rs go along because they are curious to try something new. The idea that “everyone’s doing it” can influence them to leave their better judgment behind. Besides, peer pressure can distance you from your family and friends. It is common for teenagers to think that nobodyunderstands them and that the whole world is against them. The influence of peer pressure is such that it draws them completely away from their family and friends who mean well. They just shut themselves off and fall into bad company.It’s likely that you’ve experienced the effect of peer pressure in different areas, ranging from the clothes you wear to the music you listen to. Sometimes it can be hard to resist and you may feel forced to do something you’re uncomfortable with. So being a ware of and carefully choosing the influence of peers that will lead to healthy and happy experiences is a lifelong process.63. What does the underlined part in Paragraph 2 probably mean?A. A quick reaction.B. A positive effect.C. A serious challenge.D. A potential conflict.64. According to the author, peer pressure can get teenagers to ______.A. become less self-confidentB. provide a model for teammatesC. identify characteristics of different habitsD. improve relationship with family members65. What does the author think of peer pressure?A. It makes no difference to teens’ judgment.B. It influences teens to fit into various lifestyles.C. It helps teens to relieve the uncomfortable feeling.D. It seems like a common phenomenon among teens.66. Which of the following shows the structure of the passage?A. B. C. D.I: Introduction P: Point Sp: Sub-point (次要点) C: ConclusionDI tried not to be biased, but I had my doubts about hiring Stevie. His social worker assured me that he would be a good, reliable busboy. But I had never had a mentally handicapped employee. He was short, a little fat, with the smooth facial features and thick-ton gued speech of Down’s Syndrome （唐氏综合症）. I thought most of my customers would be uncomfortable around Stevie, so I closely watched him for the first few weeks.I shouldn’t have worried. After the first week, Stevie had my sta ff wrapped around his stubby little finger, and within a month my regular trucker customers had adopted him as their official truck stop mascot. After that, I really didn't care what the rest of the customers thought of him. He was like a 21-year-old in blue jeans and Nikes, eager to laugh and eager to please, but fierce in his attention to his duties. Every salt and pepper shaker was exactly in its place, not a bread crumb or coffee spill was visible when Stevie got done with the table. Our only problem was persuading him to wait to clean a table until after the customers were finished.Over time, we learned that he lived with his mother, a widow who was disabled. Money wastight, and what I paid him was probably the difference between them being able to live together and Stevie being sent to a group home.That’s why the restaurant was a gloomy place that morning last August, the first morning in three years that Stevie missed work. He was at the Mayo Clinic in Rochester getting a heart surgery. His social worker said that people with Downs Syndrome often had heart problems at an early age and there was a good chance he would come through the surgery in good shape and be back at work in a few months.A ripple of excitement ran through the staff later that morning when word came that he was out of surgery, in recovery, and doing fine. Frannie, my head waitress, did a little dance when she heard the good news. Belle Ringer, one of our regular trucker customers, stared at her and asked, “Okay, Frannie, what was t hat all about?”"We just got word that Stevie is out of surgery and going to be okay.""I was wondering where he was. I had a new joke to tell him. What was the surgery about?"Frannie quickly told Belle Ringer and the other two drivers sitting at his booth about Stevie's surgery, then sighed: "Yeah, I'm glad he is going to be OK," she said. "But I don't know how he and his Mom are going to handle all the bills. From what I hear, they're barely getting by as it is."Belle Ringer nodded thoughtfully, and Frannie hurried off to wait on the rest of her tables.After the morning rush, Frannie walked into my office. She had a couple of paper napkins in her hand."What's up?" I asked.“I cleared off that table where Belle Ringer and his friends were sitting after they left, and I found this. This was folded and tucked under a coffee cup."She handed the napkin to me, and three $20 bills fell onto my desk when I opened it. On the outside, in big, bold letters, was printed "Something For Stevie".After three months, when Stevie was supposed to be back to work, there was already $10,000 in cash and checks collected, all from truckers and trucking companies that heard about his problems.So once again we could see Stevie, with a big, big smile on his face, busy clearing all the cups and dishes from the table in my restaurant.67. Why did the author have doubts about hiring Stevie?A. Because Stevie was not that reliable.B. Because Stevie was mentally disabledC. Because Stevie was too short and fat.D. Because Stevie was bad-tempered68. By saying the underlined sentence in Para 3, the author meant that the money she paid Stevie____.A. could help Stevie out of the troubleB. couldn’t thoroughly solve Stevie’s problemC. could make a great difference to Stevie’s lifeD. could send Stevie to a group home69. Why did Frannie sigh after she got word that Stevie would be OK?A. She was worried that the owner would fire Stevie.B. She was worried about Stevie’s health.C. She was worried about Stevie’s finance problem.D. She was worried that no one would help Stevie.70. Stevie was popular among the staff and customers in the restaurant because of____.A. his special appearance.B. his hard work and optimism.C. his funny speeches and actions.D. his kind-hearted behaviour.第Ⅱ卷（三部分共35 分）第四部分: 任务型阅读(共10小题; 每小题1分, 满分10分)Your life is composed of all the little things we experience everyday, and knowing how to find joy in some of those little things is one of the easiest ways to let happiness slowly fill your cup. In order for that to happen, you need to do two very simple things, put yourself in such situations that you can experience happiness there, and then find a way to enjoy the experience and let it sink into you.To put yourself in the position of experiencing happiness every day, Lahan Catalino, Ph.D, at the University of California, San Francisco, recommends an approach called “prioritizing positivity”—organizing your day-to-day life on purpose so that it contains situations which naturally give rise to positive emotions. It involves both taking time off from your daily routine to do things that you really love and heavily weighing the positive emotional consequences of major life decisions, like taking a new job, and you will regularly find yourself.Then how can we find a way to enjoy the happy experience and let it sink into you? Here is what psychologist Rick Hanson, the author of Buddha’s Brain explains.Let a good fact become a good experience.Often we go through life and some good thing happens—a little thing like we checked off an item on our To-Do list, we survived another day at work, the flowers are blooming, and so forth. Hey, this is an opportunity to feel good. Don’t leave the money lying on the table: recognize that this is an opportunity to let yourself truly feel good.Really enjoy this positive experience.Practice what any school teacher knows: if you want to help people learn something, make it as serious as possible—in this case, as felt in the body as possible—for as long as possible.When sinking into this experience, sense your intention that this experience is sinking into you.Sometimes people do this through imagination, like by sensing a golden light coming into themselves. You might imagine a jewel going into the treasure chest in your heart—or just know that this experience is sinking into you, becoming a resource you can take with you no matter where you go.It might seem a little clichè(陈词滥调) to say “stop and smell the roses”, but it’s moments like those that can be stored in your happiness bank and taken out later. Living a happy life can be as simple as accepting the happiness that’s already around you. If you want more, it’s OK to go o ut and achieve it, but don’t forget where happiness really comes from.第五部分: 根据所给中文提示或者首字母，写出对应的单词，注意形式。
