中科大、国科大等7所高校2019年自主招生综合评价笔试、面试真题
中科大、国科大等7所高校2019年自主招生综合评价笔试、面试真题中国科学技术大学~自主招生数学部分共8个填空题、3个解答题，分值为100;物理部分共10个选择题、6个大题，分值为100。
根据考生回忆，物理部分中规中矩，而数学部分整体格式类似高中数学联赛一试，难度和联赛一试相仿。
以下是部分真题。
填空题(1)二元绝对值不等式控制区域求面积，一个小难点是两个绝对值都是二元的。
如果第一时间抓住图形对称中心，分类讨论起来并不困难。
(2)考查三角形和向量结合类型题目，具体来说就是“奔驰定理”。
若知道结论可以快速解答，不知道的话就需要一些时间来推论了。
(3)有一道送分题，表面看上去是在考察代数，实际上可以转化为一个圆和一个定点的距离问题。
涉及到二次曲线参数方程的知识。
解答题(1)直接考查计数原理中的完全错排数，剩下就是计算了。
(2)数论题目，要用到二试以上的知识点，涉及的知识有费马小定理，欧拉定理。
题目难度较大，没有学过竞赛的题目根本无从下手。

Each passage is followed by five questions or statements. Choose the best answer to each question or decide T/F for each statement.Passage OneMan has always wanted to fly. Some of the greatest men in history had thought about the problem. One of them, for example, was the great Italian artist, Leonardo Da Vinci. In the sixteenth century he made designs for machines that would fly, but they were never built.Throughout history, other less famous men had wanted to fly. An example was a man in England 800 years ago. He made a pair of wings from chicken feathers. Then he fixed them to his body and jumped into air from a tall building. He did not fly very far. Instead, he fell to the ground and broke every bone in his body.The first real steps took place in France, in 1783. Two brothers, the Montgolfiers, made a very large "hot air balloon". They knew that hot air rises. Why not fill a balloon with it? The balloon was made of cloth and paper. In September of that year, the King and Queen of France came to see the balloon. They watched it carry the very first air passengers into the sky. The passengers were a sheep and a chicken. We do not know how they felt about the trip. But we do know that the trip lasted eight minutes and that the animals landed safely. Two months later, two men did the same thing. They rose above Paris in a balloon of the same kind. Their trip lasted twenty-five minutes and they traveled about eight kilometers.(1) Leonardo Da Vinci made designs for flying machines.(A) F(B) T分值：2(2) Eight hundred years ago an Englishman made a kind of flying machine.(A) T(B) F分值：2(3) In fact, the Englishman who tried to fly lost his life.(A) T(B) F分值：2(4) The very first air passengers in the balloon were two Frenchmen.(A) F(B) T分值：2(5) The two Frenchmen rose above Paris in November 1783.(A) T(B) F分值：8部分正确得分：83.Passage TwoThe fourth Thursday in November is called Thanksgiving Day. In the United States, it is an annual occasion to show thanks to God for his goodness.As a historical, national and religious holiday, Thanksgiving Day began with the English in Plymouth Colony. As far back as 1621, after a long bitter winter and the gathering of the firstharvest, these early settlers shared a feast with the local Indians and offered prayers of thanksgiving. The first national Thanksgiving Day was proclaimed（颁布）by President Washington on November 26, 1789. President Lincoln revived the custom in 1863.It was not until 1941 that the U.S. Congress adopted a resolution（决定）, setting the fourth Thursday of November as an annual Thanksgiving Day. Thus what began as a religious celebration of the harvest has since become a nationwide holiday.Now Thanksgiving Day is usually a family day, celebrated with a traditional turkey dinner and a happy reunion. Schools are closed on Thanksgiving Day and the day after. Many people, including students studying in another state, often travel long distances to spend the holiday at home.(1) The passage is mainly about how Thanksgiving Day came into being.(A) F(B) T分值：2(2) Thanksgiving Day was first celebrated in 1621 by English settlers of the Plymouth Colony.(A) T(B) F分值：2(3) President Washington set Thursday, November 26, 1789 as the First National Thanksgiving(A) F(B) T分值：2(4) Since 1863, the fourth Thursday of November has been set as an annual Thanksgiving Day, a nationwide holiday.?(A) F(B) T分值：2(5) The pattern of the Thanksgiving celebration has not changed through the years. The basic traditional food on Thanksgiving Day is roast turkey.(A) T(B) F分值：2部分正确得分：64.Passage ThreeNot all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares (噩梦).Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase (抹去), the effect of painful memories.In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested thatonly the emotional effects of memories may be reduced, not that the memories are erased.The research has caused a great deal of argument. Some think it is a bad idea, while others support it.Supporters say it could lead to pills that prevent or treat soldiers’troubling memories after war. They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.”said Roger Pitman, a professor of psychiatry at Harvard Medical School. “This could relieve a lot of that suffering.”But those who are against the research say that it is very dangerous to change memories because memories give us our identity. They also help us all avoid the mistakes of the past.“All of us can think of bad events in our life that were horrible at the time but make us who we are. I’m not sure we want to wipe those memories out,”said Rebecca Dresser, a medical ethicist.(1) The passage is mainly about _____________.(A) a new research on memories(B) a new medical invention(C) a way of erasing painful memories(D) an argument about the research on the pill分值：2(2) The drug tested on people can _____________.(A) cause the brain to fix memories(B) stop people remembering their experiences(C) prevent body producing certain chemicals(D) wipe out the emotional effects of memories分值：2(3) We can infer from the passage that _____________.(A) people doubt the effects of the pills(B) the pill has probably been produced in America(C) taking the pill will do harm to people’s health(D) the pill will stop people’s bad experiences分值：2(4) Which of the following does Rebecca Dresser agree with?(A) Some memories can ruin people’s lives.(B) People want to get rid of bad memories.(C) Experiencing bad events makes us different from others.(D) The pill will reduce people’s sufferings from bad memories.分值：2(5) The underlined word “scars”in Paragraph One is close in meaning to _____________.(A) experiences(B) pains(C) good stories(D) memories分值：2部分正确得分：65.Passage FourScientists find that hard-working people live longer than average men and women. Career women are healthier than housewives. Evidence shows that the jobless are in poorer health than jobholders. An investigation shows that whenever the unemployment rate increases by , the death rate increase correspondingly (相应地) by . All this comes down to one point: work is helpful to health.Why is work good for health? It is because work keeps people busy away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest are those who are busy. Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality. By work people come into with each other. By collective activity they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man spiritually and makes him ill.Besides, work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.From the above we can come to the conclusion that the more you work the happier and healthier you will be. Let us work hard and study and live a happy and healthy life.(1) The underlined word “average”in Paragraph One means _____________.(A) healthy(B) lazy(C) ordinary(D) poor分值：2(2) The reason why housewives are not as healthy as career women is that _____________.(A) housewives are poorer than career women(B) housewives have more children than career women(C) housewives have less chance to communicate with others(D) housewives eat less food than career women分值：2(3) Which of the following statements is TRUE according to Paragraph 2 ?(A) High achievers don’t care about their families.(B) There is no friendship and warmth at home.(C) Busy people have nothing to do at home.(D) A satisfying job helps to keep one healthy分值：2(4) We can infer from the passage that those who do not work _____________.(A) will lose everything at home(B) are likely to live a shorter life(C) can live as long as those who work(D) have more time to make new friends分值：2(5) The best title for this passage may be _____________.(A) People Should Make More Friends by Work(B) Working Hard Is Good for Health(C) People Should Find a Job(D) The Loss of Word Means the Loss of Everythin分值：2完全正确得分：106.Part III Grammar and Vocabulary (20 points)Directions: There are ten incomplete sentences in this part.

2019年中国高校自主招生、三位一体招生考试真题及参考答案
【导语】整理了2019年中国⾼校⾃主招⽣、三位⼀体招⽣考试真题及参考答案，希望对⼤家有帮助，⼀起看看吧。
清华⼤学2019年⾃主招⽣&领军计划考试时间为90分钟，采⽤的是机考的形式，总共35个不定项选择题。
根据报考专业不同，有的考2门即可，有的要考3门。
物理科⽬ 物理部分总计20题，均为选择题，物理部分总分60。
第1题：考察的是⽜顿运动定律和刚体的动⼒学。
有的同学考虑使⽤动量定理，然后得到2个⽊块上升的⾼度相同；有的同学考虑的是能量守恒，所以左边的上升会更⾼⼀些，甚⾄很多物理专业⼯作者对此都产⽣了疑义。
我们在之前的⼀道模拟题中对这件事进⾏了定量分析，有意思的是，上述两种情况中，⽊块和⼦弹直接作⽤时间其实是有微⼩区别的，最终会导致结果的不同。
这道题对竞赛⽐较熟悉的同学，可以做⼀些定性和半定量的计算，从⽽得到结果。
第2题：考察的是磁矩的定义。
磁矩是竞赛⾥的⼀个专有概念，是指电流和⾯积的乘积得到的⽮量。
这个问题可以通过直接计算得到，也可以通过⼀些技巧⽅法，把这个物体等效成均匀磁化的球来做。
第3题：看起来考察的是原⼦物理，实际上，它在建了⼀个模型之后，考察的是静电和简谐振动。
在这个问题中，我们可以把它视为⼀个两体的振动，就是电⼦和原⼦核形成⼀个两体问题，中间的相互作⽤可以使⽤⾼斯定理得到。
最终结果取有效质量来做会更⽅便⼀些。
第4题：考察的是⾮惯性系的运⽤和简谐振动。
我们取到⼩车向下滑动的加速参照系当中，就可以得到⾮常简单的等效加速度。
这题运⽤的是⾮常典型的⼀个竞赛基础处理⼿法。
第5题：考察的是平衡的稳定性。
注意当物体旋转的⾓速度⾜够⼤的时候，最低的那个点不⼀定再是稳定的平衡点，⽽变成⼀个向左或向右，偏离⼀定⾓度，使稳定的平衡。
平衡的稳定性的定量分析也是竞赛⾥⾯专有的考点。
第6题：考察的是静电屏蔽。
这是⼀个⾼考和竞赛当中都有的考点。
但是，在⾼考中因为缺乏对性定理的了解，所以同学们经常对这个结论是⼀知半解的。

Each passage is followed by five questions or statements. Choose the best answer to each question or decide T/F for each statement. Passage OneAlbert Einstein had a great effect on science and history, greater than what only a few other men have achieved. An American university president once commented that Einstein had created a new outlook, a new view of the universe. It may be some time before the average mind understands fully the identity of time and space and so on-but even ordinary men understand now that the universe is something larger than ever thought before.By 1914 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited opportunities for study, but soon his peace and quiet were broken by the First World War. Einstein hated violence. The misery of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work.In the years following World War I honors were increasingly heaped on him. He became the head of the Kaiser Whihem Institute of Theoretical Physics. In 1921 he won the Noble Prize, and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.(1) Albert Einstein greatly influences science and history.(A) T(B) F(2) By 1914 the young Einstein had become famous only in his country.(A) T(B) F(3) At the Prussian Academy of Science in Berlin Einstein was busy teaching every day.(A) T(B) F(4) The misery of war made him lose interest in his research.(A) F(B) T(5) In the years following World War I Einstein gained more honors and titles.(A) T(B) F3.Passage TwoPeople have been talking about health for a long time because people know the importance of it. People's understanding of health also becomes deeper with the progress in scientific research. Recently the term "health" has come to have a wider meaning than it used to. It no longer means just the absence of illness. Today, health means the well-being of your body, your mind and your relationship with other people. This new concept of health is closely related to another term－quality of life. Quality of life is the degree of overall satisfaction that a person gets from life.Why has the emphasis of health shifted from the absence of disease to a broader focus on the quality of a person's life? One reason for this has to do with the length and conditions of life that people can now expect. Medical advances have made it possible for people today to live longer, healthier lives. Imagine for a moment that you were born in the year 1900. You could have expected on average to live until about the age of 47. In contrast, if you were born in the year 1999, you could expect to live to the age of 75.(1) Progress in scientific research helps people understand health better.(A) F(B) T(2) Today "health" no longer means just the absence of illness.(A) F(B) T(3) The new concept of health is closely related to quality of life.(A) F(B) T(4) Medical advances have nothing to do with how long people can live.(A) T(B) F(5) Even though people have been talking about health for a long time, they don’t kno w the importance of it.(A) F(B) T4.Passage ThreeNo one is glad to hear that his body has to be cut open by a surgeon（外科医生）and part of it taken out. Today, however, we needn't worry about feeling of pain during the operation. The sick person falls into a kind of sleep, and when he awakes, the operation is finished. But these happy conditions are fairly new. It is not many years since a man who had to have an operation felt all his pain.Long ago, operation had usually to be done while the sick man could feel everything. The sick man had to be held down on a table by force while the doctors did their best for him. He could feel all the pain if his leg or arm was being cut off, and his fearful cries filled the room and the hearts of those who watched.Soon after 1770, Joseph Priestley discovered a gas which is now called "laughing gas". Laughing gas became known in America. Young men and women went to parties to try it. Most of them spent their time laughing, but one man at a party, Horace Wells, noticed that people didn't seem to feel pain when they were using this gas. He decided to make an experiment on himself. He asked a friend to help him.Wells took some of the gas, and his friend pulled out one of Well's teeth. Wells felt no pain at all.As he didn't know enough about laughing gas, he gave a man less gas than he should have. The man cried out with pain when his tooth was being pulled out.Wells tried again, but this time he gave too much of the gas, and the man died. Wells never forgot this terrible event.(1) It is _______ since a man being operated felt all the pain.(A) a few more years(B) few years(C) two thousand years(D) not long(2) Long ago, when the sick man was operated on，he ________.(A) could feel nothing(B) could not want anything(C) could feel all the pain(D) could do anything(3) Using the laughing gas, the people did not seem to ________.(A) be afraid of anything(B) be ill(C) want to go to the parties(D) feel pain(4) If a man took less laughing gas than he should have when an operation went on, he ________.(A) felt nothing(B) felt very comfortable(C) still felt pain(D) would die(5) One who took too much of the laughing gas ________.(A) would laugh all the time(B) would die(C) would never feel pain(D) would be very calm5.Passage FourAll over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer.Sports change with the season. People play different games in winter and summer.Games and sports often grow out of people's work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too.Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. Some sports or games go back to thousands of years ago, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person's character. One learns to fight hard but fight fair, to win without pride and to lose with grace.(1) According to this passage we know that ________.(A) people began to play about one hundred years ago(B) not all the games have a long history(C) about 100 years ago people ran or jumped when they played(D) basketball has a longer history than volleyball(2) The writer didn't tell us in this passage that ________.(A) basketball was invented in America(B) sports change with the season(C) games and sports often grow out of people's work and everyday activities(D) football is played all over the world(3) People all over the world enjoy sports because ________.(A) sports are interesting(B) sports help to keep people healthy, happy and to live longer(C) sports help to train one's character(D) all of the above(4) From this passage we can see that _______.(A) sports and games are only useful to the old(B) according to the author sports and games are significant to our life in many respects(C) sports and games are unimportant things that people do(D) sports and games should be treated only as amusement(5) What's the writer's attitude towards sports?(A) positive(C) neutral(D) negative6.Part III Grammar and Vocabulary (20 points) Directions: There are ten incomplete sentences in this part. For each sentence there are four choices marked A), B), C) and D). Choose the ONE answer that best completes the sentence.(1) It was great pleasure ____________ me to be invited to the party(A) for(B) on(C) of(D) to(2) I had to buy _____________ these books because I don’t know which one was the best.(A) all(B) none(C) neither(D) some(3) On in London, Smith went to visit his friends.(A) reaching(B) getting(C) coming(D) arriving(4) I’m afraid the box is ____ heavy for the boy.(A) much too(B) too much(C) very too(D) too very(5) Let's be ready; it's time we__________.(A) play football(B) will play football(C) are playing football(D) played football(6) Neither Bill nor his parents _____ at home(A) has(B) is(C) are(D) was(7) I don’t think I’ll need any money but I’ll bring some_____.(A) in case(B) at last(C) in time(D) once again(8) A new cinema _____here.

And there are five choices marked A), B), C), D) and E). Match each blank with the right choice.Passage OneWe can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about (41) _____. “Did Jerry really care when I broke up with Helen?” “When I got that great job, did Jerry really feel good about it as a friend?” Or “Did he envy my luck?” When we look back, doubts like these can make us feel bad. But when we look back, it’s too (42) _____.Why do we go wrong about our friends — or our enemies? Sometimes what people say hides their real meaning. And if we don’t really listen, we (43) _____ the feeling behind the words. Suppose someone tells you, “you’re a lucky dog.” Is he really on your side? If he says, “You’re a lucky guy” or “You’re a lucky gal”, that’s being (44) _____. But “lucky dog”? There’s a bit of envy in those words. Maybe he doesn’t see it himself. But bringing in the “dog” bit puts you down a little. What he may be saying is that he doesn’t think you deserve your luck.How can you tell the real meaning behind someone’s words? One way is to take a good look at the person talking. Do his words fit the way he looks? His posture (体态)? The look in his eyes? Stop and think. The minute you spend thinking about the (45) _____ meaning of what people say to you may save another mistake.(1) （41）(A) late(B) friendly(C) miss(D) people(E) real(2) （42）(A) friendly(B) real(C) people(D) late(E) miss(3) （43）(A) late(B) people(C) miss(D) real(E) friendly(4) （44）(A) real(B) miss(C) late(D) friendly(E) people(5) （45）(A) late(B) miss(C) people(D) friendly(E) real8.Passage TwoA story is told about a soldier who was finally coming home after having fought in Vietnam. He called his parents from San Francisco. “Mom and Dad, I'm (46) _____ home, but I've a favor to ask. I have a friend. I'd like to bring him home with me.”“Sure,” they replied, “we'd love to meet him.”“There's something you should know,”the son continued, “he was (47)_____ pretty badly in the fighting. He stepped on a land mine（地雷）and lost an arm and a leg. He has nowhere else to go, and I want him to live with us.”“We're sorry to hear that, son. But, maybe we can help him find somewhere to live.”“No, Mom and Dad, I want him to live with us.”“Son,” said the father, “you don't know what you're asking. Someone with such a handicap would be a terrible( 48) _____ to us. We have our own lives to live, and we can't let something like this interfere with our lives. I think you should just come home and forget about this guy. He'll find a way to live on his own.”At that point, the son hung up the phone. The parents heard nothing more from (49) _____.A few days later, however, they received a call from the San Francisco police. Their son had died after falling from a building. The police believed he had killed himself.The grief-stricken（悲痛欲绝的）parents flew to San Francisco and were taken to the city morgue（太平间）to identify the body of their son.
