it has played a very important part?For early men, there were dangers all around them — bad weather, wild animals O The keys to keep on living lay in man’s ability to remember these dangers and the ways he had dealt with them in the past O In order for memories to be stored, the human brain became more complex O And as man learned how to deal with them, he became civilized (文明)O Surprisingly, scientists today understand little about memory and how it works O They have not yet found a way to open up the brain and observe its function without destroying it O Perhaps there are two types of memory — short-term and long-term O Short-term refers to those facts that stay with us for a few seconds to a few hours O For instance, when you stay at a hotel, you remember the room number and forget it as soon as you leave O Long-term memory, on the other hand, means you remember things for a long period of time O If you spend your honeymoon in a particular hotel, it’s likely that you’ll remember your stay quite clearly OScientists also believe that a short-term memory can become along-term memory through consolidation (巩固)O A lot of chemical and physical changes take place in the part of the brain O Although the human brain weighs three pounds, it contains 30 billion nerve cells (神经细胞) acting like a computer O When those changes strengthen the links (联系) in certain nerve cells, a thought becomes a part of the long-term memory O 41O According to the author, without the development of man’s memorythere would be ____OA O no modern worldB O no recorded historyC O no animalsD O no dangers42O Scientists’ knowledge about the function of brain is ______OA O interestingB O not enoughC O greatD O encouraging43O Short-term memory can change into long-term memory on

(完整版)必修4经典练习题及答案
必修4第一章单元测试本试卷三角函数的大框架下,主要借助正弦函数和余弦函数这两种模型,从函数的定义域、值域、单调性、奇偶性,特别是新学习内容-----周期性出发,以这五个方面为主要内容而命制。
试卷中首先突出了弧度制的应用,函数状态下,弧度制的应用显然多于角度制,所以对这一学生较难接受的新概念,要在应用中体现其重要性。
其次,重基础,试卷加强了对知识形成过程的重视及拓宽。
优适当加强试题的灵活性。
第三,对数形结合的数学思想试题也比较突出。
第21题用单位圆可以做,用函数图像也可以做。
第四,体现了数学模型之间的互相转化。
反映出普遍联系的客观规律。

Of course this is not surprising. Without the nose we could not breathe or smell. It is the part of the face that gives a person special character. Cyrano De Bergerac said that a large nose showed a great man—brave, polite, manly, and bright. A famous woman poet wished that she had two noses to smell a rose. Blaise Pascal, a French philosopher(哲学家)made an interesting comment about Cleopatra's nose. “If it had been shorter,”he said,“it would have changed the whole face of the world.”Historically, man's nose has had an important role in his imagination. Man has referred to the nose in many ways to express his feelings. Expressions about the nose refer to human weakness, anger, pride, jealousy(嫉妒)and revenge(报复). In English there are a number of phrases about the nose. For example, “To_hold_up_one's_nose”expresses a basic human feeling—pride. People can hold up their noses at people, things and places. The phrases, to be led around by the nose, shows man's weakness. A person who is led around by the nose lets other people control him. On the other hand, a person who follows his nose, lets his instinct guide him.For the human emotion of rejection, the phrase to_have_one's_nose_put_out_of_joint is very descriptive. The expression applies to persons who have been turned aside because of a competitor. Their pride is hurt and they feel rejected. This expression is not new. It was used by Erasmus in 1542.This is only a sampling of expressions in English dealing with the nose. There are a number of others. However, it should be as plain as the nose on your face that the nose is more than an organ for breathing and smelling!36.This passage is about________.A.the human nose, an organ for breathing and smelling B.the nose giving various expressions C.a woman poet's wish was to have two noses D.interesting comments made on Cleopatra's nose 37.According to Blaise Pascal, “Cleopatra's nose”________.A.did change the whole face of the world B.should be shorterC.represents her powerful character D.had been cut shorter38.“To hold up one's nose”is an expression of________.A.contempt B.revenge C.anger D.jealousy39.A ma n who is described as“to have one's nose put out of joint”________.A.is happy B.wants to sell a flower C.is ill D.feels hurt and rejectedBTears are nature's way making us feel comfortable. When our eyes are made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and“redeyes”from overwork and late hours, tears from in our eyes to clean and refresh them.Tears are also a sign of strong emotion. We cry when we are sad and we cry when we are happy.And tears seem to be uniqueness(唯一)of human. We know that animals also experience emotion—fear, pleasure, loneliness—but they do not shed(流)tears. From this we can conclude that tears are closely related to the emotional and biological makeup of the human species.Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland(腺)in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animals are the end product of a long evolutionary(进化的)process that began in the sea.And it is clear that, in addition to(除了)the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and cerate a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge(合并)into one and make us even more“human”than we would otherwise be.40.According to the passage, human beings may have originated in________.A.the sea B.the salt C.chemicals D.animals41.Which of the following is NOT a function of tears?A.Biological. B.Emotional. C.Political. D.Chemical.42.According to the article, which of the following is unique to humans?A.The feeling of loneliness. B.The state of feeling good.C.The ability to shed tears. D.The feeling of fear.43.The word“aliminate”probably means________.A.add B.produce C.replace D.removeCIn early October, thousands of people around the globe stepped outside to gaze at their local night sky. As part of an event called the Great World Wide Star Count, adults and kids of looked for one of two constellations(星群)—Cygnus in the Northern Hemisphere and Sagittarius in the Southern Hemisphere. The observers recorded how many stars they saw and how bright the stars were, and then posted their results online.The Star Count was part of global effort to help scientists learn more about how light pollution affects our view of the night sky. Whether participants saw thousands of stars—or just a dozen—depended a lot on whether they were surrounded by darkness or by twinkling city lights.Dark spots on the map, above, show the locations of people who partcipated in the first annual Great Worldwide Star Count. Over 2 weeks, people in 64 countries made 6,624 observations.On a clear night, with no clouds, moonlight, or artificial lights to block the view, people can see more than 14,000 stars in the sky, but when people are surrounded by city lights they're lucky to see 150 stars.If you've ever driven toward a big city at night and seen its glow from afar, you're witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates the night sky. This light makes many stars invisiable to people on Earth.Dust and particles of pollution from factories and industries worsen the effects of light pollution. When these particles float into the atmosphere, light ricochets(跳飞)off of them and scatters even more.Light pollution doesn't fly affect star visibility. It can harm wildlife too. Scientists don't entirely understand how animals navigate at night, but it's clear that artificial light can attract them, making them go off course. There's increasing evidence, for example, that migrating birds use sunsets and sunrises to help find their way.44.Why did do many people look at the local sky?A.To enjoy the beauty of the stars. B.To develop their interest in Astronomy.C.To help scientists do a research on light pollution. D.To get the exact number of star in the sky. 45.When people are surrounded by artificial lights, ________.A.they can find more stars in the sky B.the stars might appear more clearlyC.the stars seem to be bigger D.they can find far fewer stars46.What does the word“illuminates”probably means in this passage?A.make...bright B.make...invisible C.make...beautiful D.make...clear47.How does light pollution affect birds?A.It does great harm to their eyes at night. B.It mistakes them the way when they migrate.C.It can enable them to see their routes clearly. D.It can make them find their way easily. 48.According to the maps above, which continent has fewest participants in the Star Count?A.North America. B.Australia. C.South America. D.Africa.DDr Wiseman started“the laugh lab”project in September 2001. It is the largest study of humour. Participants(参加者)are invited to log onto the laugh lab website, give a few personal details, tell their favourite jokes and judge the jokes told by other people.The project will last for a year, and the organizers hope to finally discover the world's funniest joke. But there is aslo a serious purpose. The researchers wnat to know what people from different nations and cultures find funny. And they want to find out the differences between the male and female sense of humour. The idea is that if we want to understand each other, we have to find out what makes us laugh.This is a subject that has long interested psychologists(心理学家)and philosophers(哲学家). Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves.By December 2001 over 10,000 jokes had been submitted. This gave the scientists enough evidence(证据)to make early conclusions. It seems that men and women do have different senses of humor, for instance.“Our findings show the major differences in the ways in which males and females use humour,”said Dr Wiseman. “Males use humour to appear superior(优越)to others, while women are more skilled in languages and prefer word play.”Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called“toilet humor”. But the French like their jokes short and sharp:“You're a high priced lawyer. Will you answer to questions for $ 500?”“Yes. What's the second question?”The Germans are famous for not having a sense of humor. But the survey found that German participants were more likely to find submitted jokes funny than any other antionality. Perhaps that provdes the point.Is this joke funny? I don't know, but let's say yes, just to be safe.Dr Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.49.Scientists started“the laugh lab” project________.A.to find the funniest joke in European countries.B.to know what funny people are from different nations and culturesC.to find out the differents between the male and female sense of homorD.to get more personal details about participants50.We can infer from the passage that________.A.most of the people all over the world are completely honestB.psychologists and philosophers take interest in“the laugh lab”projectC.ordinary people are not interested in“the laugh lab”project at allD.people tell the truth about themselves only when they laugh51.What is the main idea of the 4th and 5th paragraph?A.Man and woman have different senses of humour.B.Male and female have similar senses of humour.C.About 10,000 jokes have been submitted from September 2001 to December 2001.D.Scientists have collected enough evidence to make conclusions.52.The writer gave the examples of the British, the French and the Germans________.A.to show the French people have a better sense of humourB.to prove the British people have a sense of“toilet humour”C.to show people from different nations have different senses of humourD.to prove that the Germans have no sense of humourEWhen several different people look at the same person, it is not unusual for each of them to see different things:when you alone observe one behaviour or one person at two different times, you may see different things. The following are some of the factors that lead to these varying perceptions(感知).Each person's perceptions of others are formed by his or her own cultural conditioning, education, and personal experience.1. Sometimes perceptions differ because of what we choose to observe and how we deal with what we've observed. It is not necessarily true that a person's perceptions is based on observations of a particular person. You observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same yardstick(标准)to measure their parents, their friends and strangers.2.Sometimes we see only what we want to see that may be observe(对应面)to others because of our own needs, desires, or temporary(临时的)emotional states. This is a process known as selective perception. Selective perception is obviously more diffcult when contradictory(矛盾的)information is particularly obvious, but it can be done. We can ignore the stimulus——“He's basically a good boy, so what I saw was not shoplifting.”We can reduce the importance of the contradictory information—“All kids get into mischief. Taking a book from the bookstore isn't such a big deal.”We can change t he meaning of the contradictory information—“It wasn't shoplifting because he was going to pay for it later.”53.Observations of the same person by two people at the same time may differ because________.A.their yeardsticks are not the sameB.either of them may be slow to catch informationC.the time for observation is not long enoughD.each of them uses different languages to express his or her impressions54.The underlined word“ignore”in paragraph 4 means to________.A.understand somethingB.try to do somethingC.pay no attention to somethingD.know something better55.The worst thing in selective perception is that________.A.perceived information runs against your desireB.facts can be totally ignored and distorted(扭曲)C.importance of contradictory information can be overrated(估计过高)D.the same information may not be dealt with in the same way必修四Module 3答案1:D given in“投降”;give out“分配;用完”;give away“送给;泄露”;give up“放弃”2:C promise后面的句子是promise的同位语从句,同位语从句中含有条件状语从句。

必修4课后习题及答案
必修4课后习题及答案【习题一】题目:请根据所学知识,简述牛顿第二定律的基本原理及其在日常生活中的应用。
要求:答案应包括牛顿第二定律的数学表达式,以及至少两个实际应用的例子。
答案:牛顿第二定律的基本原理是描述力和加速度之间的关系,其数学表达式为:\[ F = ma \],其中\( F \)代表作用在物体上的合力,\( m \)是物体的质量,\( a \)是物体的加速度。
这个定律表明,作用在物体上的合力等于物体质量与加速度的乘积,即力是改变物体运动状态的原因。
在日常生活中,牛顿第二定律的应用非常广泛。
例如:1. 汽车制动时,车辆受到的制动力越大,车辆的减速度就越大,从而能够更快地减速或停止。
2. 运动员投掷铅球时,施加在铅球上的力越大,铅球获得的加速度就越大,从而能够投掷得更远。
【习题二】题目:解释什么是化学反应的平衡状态,并给出一个化学反应达到平衡状态的例子。
要求:答案应包括平衡状态的定义,以及至少一个具体反应的例子。
答案:化学反应的平衡状态是指在一个封闭系统中,正反应和逆反应进行得同样快,反应物和生成物的浓度保持不变的状态。
在平衡状态下,虽然正逆反应仍在进行,但宏观上看不到任何变化。
例如,氮气和氢气合成氨的哈伯过程:\[ N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g) \]在这个反应中,当氮气和氢气以一定的比例混合并在一定条件下反应时,会生成氨。
当反应达到平衡时,氮气、氢气和氨的浓度不再发生变化,反应速率相等,此时系统就达到了化学平衡状态。
【习题三】题目:请根据所学知识,解释电磁波的产生原理,并列举三种常见的电磁波。
要求:答案应包括电磁波产生的原理,以及三种电磁波的名称和应用。
答案:电磁波是由变化的电场和磁场相互作用产生的波动现象。
当电荷加速运动时,会在周围空间产生变化的电场,这个变化的电场又会产生变化的磁场,反之亦然。
这种电场和磁场交替变化并向外传播的过程,就形成了电磁波。

2017-2018学年高中英语必修4练习:单元综合测评-Unit 1 Women of achievement 含答案 精品
单元综合测评(一)Ⅰ.阅读理解(共15小题;每小题2分,满分30分)AWorldfamous violinist Itzhak Perlman was stricken with polio as a child.As a result,he wears braces on both legs and walks with the aid of crutches.At_concerts,getting_on_stage_is_no_small_achievement_for_him.He slowly crosses the stage until he reaches his chair.He lays his crutches on the floor,slowly undoes the clasps (扣环)on his legs,puts one foot backward and extends the other one forward.Then he bends down and picks up the violin,puts it under his chin(下巴),nods to the conductor,and starts to play.One fall evening in 1995,while performing at Avery Fisher Hall at Lincoln Center in New York City,Perlman had to deal with one additional trouble.Jack Reimer,a famous reporter with the Houston Chronicle,described the scen e.“Just as he finished the first few bars,one of the strings on his violin broke.You could hear the sound go off like gunfire across the room.There was no mistaking what that sound meant.”There was no mistaking what he had to do.People who were there said,“We figured he would have to get up...to either find another violin or find another string for this one.”But he didn't.Instead he waited a moment,closed his eyes,and then signaled the conductor to begin again.The band and he played from where he had left off.He played with enthusiasm and power.Of course,it is important to play a symphonic work with just three strings.But that night Itzhak Perlman refused to know that.You could see him modulate (调音),change,recompose the piece in his head.At one point,it sounded like he was turning the strings to get new sounds they had never made before.【语篇解读】本篇是人物故事,叙述了著名残疾人演奏家Perlman演出过程中发生的意外和他的应对措施。

What follows is a list of some of these untruths and some tips to help you do your best at your next interview.Myth 1: The aim of interviewing is to obtain (means "get") a job offer Only haft true. The real aim of an interview is to obtain the job you want. That often means rejecting job offers you don't want! So before you do please an employer, be sure you want the job.Myth 2: Always please the interviewerNot true. Try to please yourself. Of course, don't be hostile (敌对的) —nobody wants to hire someone disagreeable. But there is plainly a middle ground between being too ingratiating (逢迎) and being hostile.Myth 3: Try to control the interviewNobody "controls" an interview. When someone tries to control us, we resent (怨恨) it. When we try to control others, they resent us. Remember you can't control what an employer thinks of you, just as he can't control what you think of him. So be ready to give and take when being interviewed; never control the interview.Myth 4: Never interrupt the interviewerStudy the style of an effective conversationalists: they interrupt and are interrupted! An exciting conversation always makes us feel free — free to interrupt, to disagree, to agree enthusiastically (热情地). Just hang loose. Try being yourself for a change.
