AMy students often tell me that they do not have “enough time” to do all their schoolwork. My reply is often a brief “You have as much time as the president.” I usually carry on a bit about there being twenty four hours in the day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.Once in graduate school, I tried to justify (证明．.....有理) myself to one of my professors by saying that I was working hard. His answer to me was, “That's irrelevant（和……不相关的）. What's important is the quality of your work.” Since then I have had time to reflect on the “hard worker” dodge (妙计)，and I have come to some conclusions, all relevant to the issue of how much time we have.If you look at the matter analytically, you can identify two parts of the problem: There is, of course, the matter of “time”，which we can think of as fixed. Then there is the issue of “work” during that time, which can vary in intensity. But, as my professor suggested, it's not the diligence(勤奋) of the work but the quality of the product that's important.That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone's office: “Don't work harder. Work smarter.” There's a lot of sense in that idea.If you can't get more time, and few of us can, the only solution is to improve the quality of the work. That means devising(想出) ways of getting more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”，the expression “work habits” should be read as “study habits”．Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off across the board in all your studies.21．From the passage, we know that the author is most probably ______.A．a poet B．an educatorC．a novelist D．an engineer22．We can infer from the second paragraph that students still ______.A．have enough timeB．can meet the presidentC．can get something done wellD．should accept the teacher's suggestion23．Which of the following would be the best title for the passage?A．Not an Acceptable ExplanationB．Don't Work Harder. Work SmarterC．An Analysis of Our Work HabitsD．Read Better And Write BetterBMake A Difference Day is the largest national day of community service in the USA, which takes place on the fourth Saturday of October.Who takes part in Make A Difference Day?Anyone! Young and old, individuals and groups, anyone can carry out a volunteer project that helps others. It might be as ambitious as collecting truckloads of clothing for the homeless, or as personal as spending an afternoon helping an elderly neighbor or relative. USA WEEKEND covers volunteers and their projects in articles and photos.How do I get started?Look around your community. Are people hungry, homeless or ill? Are parks or schools dirty or neglected? No matter where you live, there's a need nearby. And on Make A Difference Day, millions of Americans are expected to roll up their sleeves to help others. Y ou can act alone or enlist your friends, family and co-workers.You can also call the Make A Difference Day Hot Line, 1－800－416－3824, for information. Or use the ideas on this website for inspiration.What do I do after I've selected a project?Tell others what you're doing and enlist help. Several weeks before the day, tell us about your plans in the Make A Difference DAY, a national listing of local projects that will be viewed by interested volunteers, other people looking for good project ideas and news media looking for good stories to tell. It will only take a few minutes to post your plans in the DAY hosted by Hands On Network.Do it!Carry out your plans to help others on Make A Difference Day. Be sure to take lots of pictures and share them on the Make A Difference Day Photo Album.24．Where does the text probably come from?A. A magazine.B. A website.C. A newspaper.D. A festival brochure.25．Make A Difference Day ________.A. is celebrated every year all over the worldB. is a service provided by the communityC. is a celebration of helpful neighborsD. is a national day of doing good in America26．It can be inferred from the text that volunteers ________.A. are chosen carefully by USA WEEKENDB. need to dress up on Make A Difference DayC. can get good project ideas from Hands On NetworkD. take pictures to send them to news media for money27．The main purpose of the text is to ________.A. introduce the origin of Make A Difference DayB. instruct people how to select a proper project ideaC. promote Make A Difference Day to other countriesD. encourage individuals to join in Make A Difference DayCYou wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the drama starts. The person on the other end has a depressing（压抑的）tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. You are still in a wonderful mood? Impossible!Communicating with negative（消极的；负面的）people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel depressed for a moment or a long time.Life brings ups and downs, but some people are stuck in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. No wonder they can hardly win others' pity or respect.When you communicate with positive people, your spirit stays happy and therefore more positive things are attracted. When the dagger(匕首) of a negative person is put in you, you feel the heavy feeling that all in all, brings you down.Sometimes we have no choice but to communicate with negative people. This could be a co－worker, or a relative. In this case, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person, but all this does is to lower you to that same negative level and they won't feel ashamed of themselves about that.Negativity often affects happiness without even being realized. The negative words of another at the start of the day can cling to(附着) you throughout the rest of your day, which makes you feel bad and steals your happiness. Life is too short to feel negative. Stay positive and avoid negativity as much as possible.28．The purpose of the first paragraph is to ______.A．make a comparison B．offer an evidenceC．introduce a topic D．describe a daily scene29．How can negative people have effect on us?A．By influencing our emotion.B．By telling us the nature of life.C．By changing our ways of thinking.D．By comparing their attitudes to life with others.30．Some negative people base their happiness on ______.A．other people's pity for themB．making other people unhappyC．building up a positive attitudeD．other people's respect for them31. According to the passage, to reduce negative people's influence on us, we areadvised to ______.A．change negative people's attitudes to lifeB．show our dissatisfaction to negative peopleC．make negative people feel ashamed of themselvesD．communicate with negative people as little as possibleDIn choosing a friend, one should be very careful. A good friend can help you study. You can have fun together and make each other happy. Sometimes you will meet fair weather friends. They will be with you as long as you have money or luck, but when you are down, they will run away. How do I know when I have found a good friend? I look for certain qualities (品质) of character, especially understanding, honesty and reliability (可靠).Above all else, I look for understanding in a friend. A good friend tries to understand how another person is feeling. He is not quick to judge. Instead, he tries to learn from others. He puts himself in the other person's place, and he tries to think of ways to be helpful. He is also a good listener. At the same time, however, a good friend is honest. He does not look for faults (过错) in others. He notices their good points. In short, a friend will try to understand me and accept me.Another quality of a friend is reliability. I can always depend on (信赖) a good friend. If he tells me he will meet me somewhere at a certain time, I can be sure that he will be there. If I need a favor, he will do his best to help me. If I am in trouble, he will not run away from me.There is a fourth quality that makes a friend special. A special friend is someone with whom we can have fun. We should enjoy our lives, and we would enjoy our friendship. That is why I especially like friends who are fun to be with. A good friend likes the same things I like. We share experience (经验) and learn from each other. A good friend has a good sense ofhumor (幽默), too. He likes to laugh with me. That is how we share in the joy of being friends. And I know that he is looking for the same quality in me.When I meet someone who is reliable, honest, and understanding, I know I've found a friend!32. Which of the following qualities the writer thinks is the most important in choosing a friend?A. understanding.B. honesty.C. reliability.D. a sense of humor.33. If you have fair weather friends, ______ .A. they will give you all that they have when you need helpB. you will be refused when you get into troubleC. you will become richD. you can be sure that you get real friends34. Good friends need to ______.A. always point out each other's mistakesB. be helped with moneyC. understand each other's feelingsD. have money or luck35. This passage mainly discuss ______ .A. the qualities of a friendB. where to choose friendsC. how to get along with friendsD. the importance of having a friend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，并在答题卡上将该项涂黑。

I thought of all of the friends I had made in the sport.It had been a decade since I entered a competition. Strangely, tears began to roll down my cheeks. Then, for the first time in many years, I wept openly. I tried to calm myself and walked to the bathroom to wash my face. It was there that I took a good, long, hard look at myself in the mirror.I was no longer that marathon runner. I was a middle-aged man to sit behind the desk in my office for the day and had grown content in my life and appeared comfortable with the increase in the size of my waistline.When I took a serious look at myself, I knew it was time to change. I lacked discipline (自制力) and had no readily identifiable goals. Strange quiet came over me. I was going to transform my life. It was time to reinvent myself, to become all that I could imagine. I asked myself one more question, “What are you willing to do to make this dream a reality?” The answer was a very simple one, “Whatever it takes! ”The first few days, I was filled with enthusiasm and it was easy to stay on track. I prepared myself mentally for the difficult days. As the days went by, my newly discovered disciplinedeveloped into more discipline. I vowed (发誓) to remain true to my restricted diet of 1,200 calories per day. I was running for an hour every morning and lifting weights for another hour three or four days per week. Weight began to reduce. I lost about three pounds every week. This was feeling good. I was gaining momentum and strength as each day passed. There was no doubt in my mind that I would get down to my desired weight.4．What can we learn about the author from paragraph 3?A．He used to be a lawyer.B．He was totally out of shape.C．He was no longer fit to work out.D．He had something wrong with his waist. 5．What was the author actually doing in the bathroom?A．He was reflecting upon himself.B．He was doing thorough cleaning.C．He was wiping tears off his face.D．He was dressing up in front of the mirror. 6．Which can replace the underlined word “momentum” in the last paragraph?A．weight B．motivation C．experience D．knowledge 7．How does the author mainly develop the text?A．By telling a funny story.B．By employing dialogues.C．By describing mental activities.D．By showing possible results.As summer gives way to autumn, many of us long for warmth and sunlight. It is common for some of us to feel upset when the days get shorter. People call this phenomenon autumn sadness.While autumn sadness is a common seasonal feeling we have as sunlight comes in shorter supply, for some people, it takes on a more serious form known as seasonal affective disorder, or SAD．SAD, a form of depression (抑郁症), mostly starts in late autumn or early winter and goes away in spring and summer. People who have SAD typically oversleep, overeat, and lose interest in activities they once enjoyed. Generally, almost all people suffering from SAD feel sad, helpless, and even desperate.The exact cause of SAD is not yet completely understood, but several factors have been linked to its development. Johns Hopkins University suggests that reduced exposure (接触) to natural light during the autumn and winter months may disrupt the body’s internal clock and thehormones (荷尔蒙) produced, such as melatonin (褪黑素) and serotonin (血清素), which are related to sleep and emotions, respectively. This disruption can lead to depression.Addressing SAD often requires medical help. Light therapy is a common and effective treatment. Patients are advised to expose themselves to sunlight or man-made light that imitates natural sunlight. Light therapy can help regulate patients’ hormones and get their lives back on track.Moreover, living a healthier life, such as maintaining a regular sleep schedule, taking part in regular physical activity, and having a balanced diet, can help manage SAD．But it’s also important that people seek help from a medical professional to determine the most suitable treatment plan for their specific needs.It is worth noticing that, according to the National Institute of Mental Health of the US, in most cases, SAD begins in young adulthood. So, while embracing (接受) knowledge in books and classes, don’t forget to embrace the sunlight outdoors and get energy from nature!8．What do we know about SAD?A．It usually starts in early autumn.B．It can lead to long- term depression.C．Its main symptoms include feeling sad.D．It is most commonly found in older people. 9．According to Johns Hopkins University, what is a possible cause of SAD?A．An unbalanced diet.B．A lack of sunlight.C．An irregular sleep schedule.D．A lack of physical exercise.10．What do paragraphs 5 and 6 mainly talk about?A．How people can deal with SAD．B．What people with SAD have in common.C．Who people with SAD can turn to for help.D．Why medical help is needed for people with SAD．11．What can be inferred from the last paragraph?A．Young adults are the only group affected by SAD．B．Embracing nature’s sunlight is enough to prevent SAD．C．It’s important for young adults to take outdoor activities.D．It’s never too late to embrace the beauty that nature offers.At first, they sounded distant, as if they were around a phone in a prison. But as we chatted, they slowly started to sound more like themselves. They told me personal stories I’d never heard. I learned about the first time my dad got drunk. Mum talked about getting in trouble for staying out late. They gave me life advice and told me things about their childhoods, as well as my own. It was amazing. For a moment I forgot I wasn’t really talking to my parents at all, but to their digital copies.This Mum and Dad live inside an app on my phone as voice assistants created by the company HereAfter AI. The company’s goal is to let the living communicate with the dead. Technology like this, which lets you “talk” to people who have died, has been a mainstay of science fiction for decades. But now it’s becoming a reality, thanks to advances in AI and voice technology. I wanted to test out what it might be like.My real, flesh-and-blood parents are still alive and well; their virtual versions (虚拟版) were made just to help me understand the technology. But their digital copies offer a glimpse at a world where it’s possible to have conversations with loved ones long after they’re gone. From what I could know over a dozen conversations with my virtual parents, this really will make it easier to keep the people we loved close. It’s not hard to see the attraction. People might turn to digital copies for comfort, or to mark special occasions like anniversaries.But for some, this tech may be alarming or frightening. When I talked to friends about this article, some of them just went away. There’s a common, deeply held belief that we shouldn’t mess with death.But I’m only human, and that worry ends up being washed away by the even scarier possibility of losing the people I love. If technology might help me hang onto them, is it so wrong to try?12．Why did the writer chat with his virtual parents?A．To remember his late parents.B．To learn more about his parents.C．To see how the technology works.D．To find ways to improve the technology. 13．What can we learn about the technology mentioned?A．It allows users to live on an app.B．It leads users to lose their friends.C．It is invented by a science fiction writer.D．It offers a link between the dead and the living.14．What is the writer’s attitude towards the technology?A．Supportive.B．Unclear.C．Objective.D．Doubtful. 15．Which of the following is a suitable title for the text?A．Your can talk to your parents.B．Parents appear on your phone.C．AI means never having to say goodbye.D．A breakthrough in AI may benefit you.Are you an “I person” or an “E person”? 16 These two personality labels in particular are widely discussed online. They are part of a popular personality test called the Myers-Briggs Type Indicator, or MBTI. 17 All of the results have four letters, and there are 16 results in total. “I” and “E” refer to “introverted” and “extroverted”, respectively.Even if someone is typically quiet and shy, many online discussions suggest that an “I” person can still act outgoing at times. For example, when an introverted person is with a group of introverted friends, they might become more social like an “E” person.According to psychologists, this idea of temporarily switching personalities is called “masking”. 18 Human beings want to feel they belong, and they might become people-pleasers to do so.Using the MBTI result to identify and describe someone’s personality seems fun. 19 The MBTI personality test may show something you don’t know about yourself, and can even be a fun ice-breaker question when meeting new friends. And that’s all it is, for fun. Knowing someone’s MBTI result doesn’t mean you really know this person. 20A．How can you find the answer to the question?B．However, do not go too far or take it too seriously.C．That is hiding your true personality in specific situations.D．And those four letters of yours don’t define (定义) who you are.E．But no one personality type is best or better than another.F．Have you heard someone describe themselves as an INTJ or an ESTP?G．It is a self-report list to identify a person’s personality, strengths, and preferences.二、完形填空Our neighbors had a loud party last night. We weren’t 21 but this was one of those celebrations that I didn’t mind. They are a bunch of young, single guys and I would have felt out of place.What 22 me was the way they behaved. Ono of the young men came over 23 in the day to “warn” us of the upcoming event and said it would be over at about 11 p. m. That was the first step. Even more 24 was what they did next. “Here’s my 25 ”, offered our neighbor 26 “Text me if it’s too noisy.” That was a level of 27 I had never experienced in all my years of being a neighbor!And it really worked in their favor. My husband and I were so friendly that even when the event went past the 28 end time, even when the music reached high decibels(分贝), and even when we couldn’t get through to the phone number, we felt no 29 . We knew they would stop and 30 to it eventually.It takes such little effort to make people feel that they 31 and get people on your side.

河南省实验中学2015届高三上学期期中考试 英语(Word有答案)
河南省实验中学2014——2015学年上期期中试卷高三英语（时间：100分钟，满分：150分）第I卷第一部分听力（共两节，满分30分）（略）第二部分阅读理解（共两节，满分40分）第一节（共15小题；每小题2分，满分30分）阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
AA chimpanzee (黑猩猩) is a primate (灵长类动物). This group includes tiny bush babies, monkeys, and humans. Full-grown chimps are 4 to 5feet tall. The males weigh about 100 pounds, while the females weigh 90 pounds or less. Chimpanzees have long fingers and toes (脚趾)，and they are covered with dark fur except on their faces, which are very expressive.Chimpanzee HabitatChimpanzees live in western and central Africa. Some chimps live in thick rain forests. Others live in thinner woodland.Chimps usually walk on all four legs, but they can also walk upright. Chimps are good climbers and they can swing through trees. They usually sleep in trees at night._________________________Chimps live in groups, called munities，which may contain up to 80 members. Within each munity are many smaller groups of friends and family members. Young chimps stay with their mothers until they are about 8 years old.Just like human beings who live and work in groups, some chips are more powerful than others. Getting a high position depends on more than size. Group leaders are usually strong-willed and clever.Chimps often “argue” over food to protect their children. Most quarrels end quickly, but sometimes chimps get hurt. Chimpanzees are powerful animals, and they will bite and kick if angry.Chimpanzees eat fruits, plants, insects, eggs, and small animals. They use small thin branches to “fish” inside insect nests for food. They use leaves to get water to drink. They also use stones to open nutshells.Chimpanzee municationChimpanzees municate with their voices. They shout loudly to show anger, fear and other emotions. They warn each other when enemies are near. Chimps also municate with gestures and facial expressions. If a chimp holds out its hand, it is begging for food. A hug means “Hello” or “I’m frightened.” Some chimps have even learned to use sign language.21. Which of the following can fill in the blank in the text?A. Chimpanzee BehaviorB. Chimpanzee LeadersC. Chimpanzee FightsD. Chimpanzee Diet22. According to the text, a chimpanzee munity _____.A. consists of only one familyB. may contain more than 100 membersC. considers many things when choosing a leaderD. is usually made up of members of the same age23. It can be inferred from the text that _________.A. chimpanzees are clever and gentle animalsB. chimpanzees don’t hurt others in their munityC. chimpanzees’ quarrels always last for a long timeD. chimpanzees can use their faces to show various feelingsBOne evening last summer, when I asked my 17-year-old son, Ray, for help with dinner, his response surprised me, “What’s a colander(漏勺)？” he asked.I could only blame myself. Nobody’s h ands went in the sauce except my own. But that night, as I explained with a touch of panic that a colander is the thing with holes in it, I wondered what else I hadn’t prepared Ray for.As parents, while we focus on our child’s confidence and character, we perhaps don’t always consider that we are also raising someone’s future roommate, boyfriend, husband, or father. I wanted to know that I’d raised a boy who would never ask the woman in his life, “What’s fordinner?” So I came up with a plan: I would o ffer Ray a private home economics course. I was delighted to find that he didn’t say no.For two hours, three days a week, Ray was all mine. One day, as his tomato sauce reduced on the stove, he washed and seasoned a chicken for roasting. Then he rolled out the piecrust (馅饼皮) and filled it with apples, all while listening to my explanation on the importance of preheating an oven.I knew that he would rather have shooting hoops in the driveway than learning to mend socks with his mother----he tried to beg off sewing lessons, even though I insisted that one day, someone would find the sight of him fixing his own shirt very attractive----but it couldn’t be denied that he was learning, and more than just housekeeping. “I appreciate more what you do as a mom,” he told me one day.Ray now understands the finer points of cooking, and more important, he realizes there’s nothing masculine(男子气的) about being helpless. Not only can he make his own dinner, he can make it for his family, too. That’s what I call a man.D. always thought it attractive to do housework26. The underlined part “more than just housekeeping” shows that Ray ______.A. fell in love with houseworkB. did other work in the houseC. began to be more confidentD. acknowledged the author’s efforts27. What would be the best title for the text?A. Should boys be involved in housework?B. Present for future daughter-in-lawC. I’m proud I’ve raised a curious sonD. Dependent or independent?C28. The least likely choice for 5-year-old Jack to make among the museums is______. A．T MMI B．T NYHS C．QMA D．QCFM29. According to the text, which of the following is NOT true?A．All the museums mentioned above lie in New York City.B．No other museum in New York City is better than MMI.C．Lucky visitors can see grapes in one of the museums.D．NYHS has the most hands-on activities in America.30．We can know from the text that______.A. visitors can pay a visit to all the museums by subwayB. people can visit only one of them any dayC. there is often a rare bird flying in the sky above MMID. the Panorama is, as a matter of fact, a great gift shop31. In which museum can you enjoy outdoor fun?A．MMI. B．NYHS. C．QCFM. D．QMA.DCancer researchers urged people on Wednesday to take more vitamin D to lower risk of cancer, saying st udies showed a clear link. “Our suggestion is for people to increase their intake (吸入，摄入), through diet or a vitamin supplement,” Dr. Cedric Garland said in a telephone interview.Garland's research team reviewed 63 studies, including several large long-term ones, on the relationship between vitamin D and certain types of cancer worldwide between 1966 and 2004. “There's nothing that has this ability to prevent cancer,” he said, urging governments and public health officials to do more to fortify (增强) foods with vitamin D. Garland is part of a University of California at San Diego Moores Cancer Center team that published its findings this week online in the American Journal of Public Health. Vitamin D is found in milk, as well as in some fortified orange juice, yogurt and cheeses, usually at around 100 international units（IU）a serving. “People might want to consider a vitamin supplement to raise their intake to 1000 IUs per day” Garland said, adding that it was well within the safety guidelines established by the National Academy of Sciences.The authors said that taking more vitamin D could be especially important for people living in northern areas, which receive less vitamin D from sunshine.“African Americans, who don't produce as much of the vitamin becaus e of their skin colour,could also benefit significantly from a higher intake,” the authors said.32. According to the passage, people are advised to take more Vitamin D, because__.A. it is nutritiousB. it can’t harm people’s healthC. it can lower cancer riskD. it is not taken enough every day33．Which of the following can not help people get more Vitamin D?A. Have some sunshineB. Have more meatC. Have more fortified cheeseD. Have a vitamin supplement34．Who can Garland probably be?A. A health researcherB. A doctorC. A scientistD. A public health official35. People from which area should take more Vitamin D according to the passage?A. Asian peopleB. African peopleC. American peopleD. European people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，并在答题卡上将该项涂黑。
