Investors wanted to sell their shares before the stock lost value. Over the next 5 days millions of shares flooded the market. Many investors lost all their money.During 1920s many Americans had invested in the stock market (股票市场). Many got rich.In 1928. Herbert Hoover was elected president. He said the future was bright with hope.People were being advised to buy stock before prices climbed even higher. Common sense was in short supply. Stock market rules let investors buy shares even if they did not have enough money. That is still true today but there are stronger controls.During the summer of 1929, some economists warned that there was no real value behind the high prices. President Hoover urged stock market officials to make trading safer and more honest. But he did not think the government should interfere in the market.When the drop in stock prices finally came, it was slow at first. It picked up speed (加速) as investors sold more and more shares. Several bankers bought stocks in an effort to prevent a crash. But the intense activity continued. October 29 is remembered as Black Tuesday. That day alone, stocks lost a tenth of their value.The crash (暴跌) caused a lot of people to lose their jobs, their farms and their homes. Many banks and businesses failed. The crash led to a worldwide depression (萧条) .36. The reason for the Great Crash is .A. that millions of shares flooded the marketB.

Everyone seems to think that his native (本国的) language is the most important one, as it is their first language. For many people it is even their only language all their lives. But English is the world's most widely used language.As a native language, English is spoken by nearly three hundred million people: in the U. S. , England, Australia and some other countries.For people in India and many other countries, English is often necessary for business, education, information and other activities. So English is the second language there.As a foreign language, no other language is more widely studied or used than English. We use it to listen to the radio, to read books or to travel.

The sound came from the waste basket. Walt looked at it and saw a family of mice eating pieces of bread in it. For many nights, they played there. And Walt began to like them.Walt liked one little mouse better than any of the others. This little animal gave him some new ideas for his drawing. He began to draw it. But in the picture, it did not look like a mouse, but more like a funny man. He showed it to his wife and she liked it very much, too.Walt named this little m ouse “Mickey Mouse”. He hop ed his Mickey Mouse would be different from the other pictures of his. He wanted to make Mickey talk. He put his fingers on his nose and made a strange sound.

高数练习题专升本黑龙江### 高数练习题：专升本黑龙江#### 一、选择题1. 函数 \( y = \ln(x) \) 的导数是：- A. \( \frac{1}{x} \)- B. \( x \)- C. \( e^x \)- D. \( \ln(x) \)2. 极限 \( \lim_{x \to 0} \frac{\sin(x)}{x} \) 的值是：- A. 0- B. 1- C. \(\pi\)- D. \(\infty\)#### 二、填空题1. 函数 \( y = x^2 - 4x + 4 \) 的最小值是 \( \boxed{__} \)。

2. 曲线 \( y = e^x \) 在 \( x = 0 \) 处的切线斜率是\( \boxed{__} \)。

#### 三、解答题1. 求函数 \( y = x^3 - 3x^2 + 2 \) 的极值点。

解答：首先求导数 \( y' = 3x^2 - 6x \)。

令 \( y' = 0 \)，解得 \( x = 0 \) 或 \( x = 2 \)。

检查二阶导数 \( y'' = 6x - 6 \)。

当 \( x = 0 \) 时，\( y'' = -6 < 0 \)，为极大值点。

当 \( x = 2 \) 时，\( y'' = 6 > 0 \)，为极小值点。

将 \( x = 0 \) 和 \( x = 2 \) 分别代入原函数，得到极值点坐标。

2. 计算定积分 \( \int_{0}^{1} x^2 dx \)。

解答：根据积分公式 \( \int x^n dx = \frac{x^{n+1}}{n+1} + C \)，计算 \( \int_{0}^{1} x^2 dx =\left[\frac{x^3}{3}\right]_{0}^{1} = \frac{1}{3} - 0 =\frac{1}{3} \)。

Born in 1835, Twain grew up in the Mississippi River town of Hannibal, Missouri. As did many other boys of his day ,Twain dreamed of traveling on rive boats and of someday becoming a riverboat pilot. Twain used his memories of the life of a river town in his tow most famous books, Huckleberry Finn and Tom sawyer.As a young man, Twain held many jobs. He was a printer, a good miner, and, for a time, he was a riverboat pilot. During his pilot days, he adopted the name Mark Twain. This was a term used by the boatmen to mean that the water measured two fathoms, or twelve feet, which was deep enough for safe passage.Finally Twain became a successful writer. He traveled a great deal, writing and speaking, and became very popular both in the United States and in Europe.Twain’s style of writing was simple and direct. Among the things he wrote about were superstitious(迷信)people and people who were easily fooled. He used his unusual gift for humor to write about many things of importance.61.

Questions 11～15 are based on the following passage:Scientists have tried to come up with biological explanations for the difference between boys and girls. However, none were believable enough to explain the general picture. As one scientist points out, "There are slight genetic (遗传的) differences between the sexes at birth which may affect the subjects boys and girls choose. But the difficulty is that by the time children reach school age, there are so many other effects that it is almost impossible to tell whether girls are worse at science and math, or whether they've been brought up to think of these subjects as boys “…territory‟”Statistics show that in mathematics, at least, girls are equal to boys. A recent report suggests that girls only stop studying mathematics because of social attitudes. One of the reports' authors says, “While it is socially unacceptable for people not to be able to read and write, it is still acceptable for women to say that they are' hopeless, at math. Our research shows that, although girls get the explanation for the difference, which is very clear during the teenage years goes as far back as early childhood experiences.”From their first days in nursery school, girls are not encouraged to work on their own or to complete tasks, although boys are. For example, boys and girls are often asked to “help” with repair work. This en couragement leads to a way of learning how to solve problems, later in life. Evidence shows that exceptional mathematicians and scientists did not have teachers who supplied answers; they had to find out for themselves. A further report on maths teaching shows that teachers seem to give more attention to boys than to girls.Most teachers who take part in the study admitted that they expect their male students to dobetter at mathematics and science subjects than their female students. All of this tends to encourage boys to work harder in these subjects, gives them confidence and makes them believe that they can succeed.Interestingly, both boys and girls tend to regard such "male" subjects like mathematics and science as difficult. Yet it has been suggested that girls avoid mathematics courses, not because they are difficult, but for social reasons.Mathematics and science are mainly male subjects, and therefore, as girls become teenagers, they are less likely to take t hem up. Girls do not seem to want to be in open competition with boys. Neither do they want to do better than boys because they are afraid to appear less female and so, less attractive.11. The underlined word" territory" in the first paragraph most probably means .A. special fieldB. interestC. the landD. map12. According to scientific study, .A. math is not fit for girls to studyB. boys have a special sense of mathC. girls are poorer at math because they are the weaker sexD. girls can learn math as well as boys if given enough encouragement13. Those who made extraordinary contribution in mathematics and science .A. usually had good teachers to help themB. had the abilities to solve problems by themselvesC. usually worked harder than othersD. were encouraged to repair things when young14. Which of the following is NOT true according to the text?A. It is a social problem rather than a problem of brains that girls are poor at math.B. It seems socially acceptable for a girl not to be able to read and write.C. It is not easy for boys and girls to learn math and science.D. There is no connection between a girl's beauty and her ability.15. The best headline for the passage is .A. Are boys cleverer than girlsB. Who's afraid of scienceC. Girls are poorer at math than boys at math,D. Mat h－A Difficult SubjectQuestions 16～20 are based on the following passage:It was Monday. Mrs. Smith's dog was hungry, but there was not any meat in the house.Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it: “Give my dog half a pound of meat.” Then she gave the paper to her dog and said gently: “T ake this to the butcher, and he's going to give you your lunch today.”Holding the piece of paper in its mouth, the dog ran to the butcher's. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and soon did it as he was asked to. The dog was very happy, and ate the meat up at once.At noon, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave 'it half a pound of meat once more.The next day, the dog came again exactly at noon. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at paper, and gave the dog its meat, for he had regarded the dog as one of his customers (*people who buy sth. from a shop).But, the dog came again at four o'clock. And the same thing happened once again. To the butcher's more surprise, it came for the third time at six o'clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, “This is a small dog. Why does Mrs Smith give it so much meat to eat today?”.Looking at the piece of paper, he found that there were not any words on it!16. Mrs. Smith treated her little dog quite .A. cruellyB. fairlyC. kindlyD. friendly17.

From its experience, the dog found that .A. only the paper with Mrs. Smith's words in it could bring it meatB. the butcher would give the meat to it whenever he saw itC. Mrs. Smith would pay for the meat it got from the butcherD. a piece of paper could bring it half a pound of meat20. At the end of the story, you'll find thatA. the dog was clever enough to write on the paperB. the dog dared not go to the butcher's any moreC. the butcher was told not to give any meat to the dogD. the butcher found himself cheated (*act in a way that is not honest) by the cleveranimalQuestions 21～25 are based on the following passage:Everything living on eart h－each plant and anima l－needs other living things. Nothing lives alone. Most animals must live in a group, and even a tree or a plant grows close together with others of the same kind. Sometimes one living thing hunts another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they form a food chain (食物链). Some food chains are simple, others are complicated (复杂). But all have two things in commo n－all food chains begin with the sun, and all food chains become broken up if one of the links disappears.All, life depends on energy from sunlight. Only plants can use this energy directly. Their leaves are little factories that use sunlight to make food from water and things in the soil and air.Plants in turn feed all other living things. Animals can only use the sun's energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.What about human beings? We are members of many food chains. We eat wheat, rice, vegetables, fruit and so on We also eat meat and drink milk. This means the sun's energy passes through plant to animal before it reaches us.Nature is a greater thing. Any food chain always produces enough for each of its members if it is left alone. When there isn't enough food for any link in the chain, some of its members die off. So the balance is always kept.But men in their greed(贪婪) and ignorance(无知) often break up the food chain and do great harm not only to one plant or animal, but to all the links in the chain. People make seas and rivers dirty. They destroy whole forests and kill many kinds of wild animals and birds. When a river becomes dirty, the fish cannot be eaten. Men eat the fish and get strange diseases. In some places men have no fish to eat any more, because the fish have died off. Each form of life is linked to all others. Breaking the links puts all life in danger.21. How does everything living on earth live?A. Each plant can live alone.B. Each animal can live alone.C. Everything living on earth can not live without needing other living things.D. If living things want to live they must kill each other.22. How is food for plants made? Food for plants is made .A. from waterB. from the air in the skyC. from the soilD. from water, things in the soil and air, sunlight23. How do all food chains break? All food chains are broken if .A. one kind of animal is eaten upB. one kind of plant is destroyedC. one kind of animal eats anotherD. one of the links is destroyed24. Which living things can use energy directly?A. Animals.B. Plants.C. Both animals and plants.D. All living things.25. Why is all life in danger? Because break up the food chains.A. human beingsB. animalsC. plants and animalsD. man and wild animalsQuestions 26～30 are based on the following passage:The whole body is covered with skin. The surface of the skin is dead (like the hair and the nails) , but it is made from a living layer(层) just under the surface. The outside dead layers wear off(磨损)all the time, with new ones replacing them, and the body forms a totally' new skin every three weeks.The skin protects the body from the outside world and it passes information, from the outside. It helps to keep water in the body and to keep the body at the same temperature. Bacteria (细菌) can't get in through the skin unless it is damaged.If the weather is cold, the blood vessels (血管) in the skin squeeze down, or contract (收缩) ,so that as little blood as possible comes near the surface. This means that less warmth is lost to the outside, This makes the ski1 look pale, or even “blue”. At the same time, the hairs on the skin are pulled upright by tiny muscles.When it is hot, the blood vessels expand (扩大),or get wider again, to allow plenty of blood to run near the surface of the skin. This helps the body to lose heat, and the skin may look red At the' same time, the sweat glands (汗腺)produce more sweat, which cools the skin.If your skin has ever been numb (麻木的), you will realize how important the feeling from the skin is. Nerves (神经) in the skin are sensitive(敏感的) to heat and cold, sharpness, hardness and softness, wetness and dryness and pain. If one is not able to feel these things, which can act as warnings, he is likely to be burned, cut or hurt in other ways.The colour of the skin depends on special colour cells (细胞). These are just below the top layers of the skin. They are needed as protection from some harmful ray of the sun. People with pale skins may “tan” (晒黑)in the sun. This happens when the body produces extra colour cells in the skin: for protection. In the sun, the skin produces a vitamin (vitamin D) which is needed for: strong bones.26. Which of the following statements is NOT true?A. Our hair and nails are dead like the surface of the skin.B. There is skin all over our body.C. The skin of our bodies will be completely different in three weeks.D. The surface of the skin is made of a living layer.27. The second paragraph mainly tells us about .A. the functions of the skinB. the information from the outsideC. the water in the bodyD. the temperature of the body28. Bacteria will get in through the skin .A. when one's skin is numbB. when one is illC. when the skin is cutD. when the sweat glands produce more sweat29. When the weather is cold, the skin will contract in order to .A. allow more blood is coldB. make the skin look blueC. keep warmthD. help the body lose heat30. The colour of the skin is determined by .A. the rays of the strong sunB. colour cellsC. top layers of the skinD. vitaminPart III 词汇和语法结构（本题共50分，每小题1分）从四个选项中，选出最佳答案划在答题纸的相应位置上。
