菜李渔菜为至贱之物,又非众花之等伦,乃《草本》、《藤本》中反有缺遗,而独取此花殿后,无乃贱群芳而轻花事乎?曰:不然。
菜果至贱之物,花亦卑卑不数之花,无如积至贱至卑者而盈千累万,则贱者贵而卑者尊矣。
“民为贵,社稷次之,君为轻”者,非民至果贵,民之至多至盛为可贵也。

Why are so many people so afraid of failure? Quite simple because no one tells us how t o fail so that failure becomes an experience that will lead to growth.We forget that failure is part of the human condition and that every person has the right to failure.Most parents work hard at either preventing failure or protecting their chidren from the k nowledge that they have failed.One way is to lower standards.A mother describes her chil d's hastily made table as"perfect", even though it wobbles(摇晃)on uneven legs.Another way is to shift blame.If John fails science, his teacher is unfair or s tupid.The trouble with faiure prevention devices is that they leave a child unequipped for life in t he real word.The young needno one can win all the time-and that it is possible to enjoy a game even when you don't win.A child who's not invited to a birthday party, who doesn's make the honor roll or the baseball team, feels terrible, of cour se, But parents should not offer a quick consolation(安慰)prize or say, "It doesn't matter"because it does.The young should be allowed to allowed to experience disappointment and be helped to master it.Failure is never pleasurable.It hurts adults and child alike.But it can make a positive co ntribution to your life once you learn to use it.Step one is to ask"why did I fail? "Resist the natural impulse to balme someone else.Ask yourself what you did wrong and how you can i mprove.If someone else can help, don't be shy about inquiring.to learn that no one can be best at everying.(1)This passage mainly tells us about________.A the reason why people fail.B how to fail.C the ways to prevent failures.D th e importance of facing failures.(2)The second paragraph tells us________.A how a mother praised her children.B two ways of failure prevention most parents u sed when their children fail.C how to shift blame.D parents should blame their c hildren at the proper time.(3)When the writer says"every person has the right to fail",he means"________"A the world is full of failures.B everyone makes mistakes.C failures are not comm on in our lives.D no one can grow up without failures.(4)By saying"protecting their children from the knowledge that they have failed".The writer m eans that most parents try their best________A to let their children know that they won't fail.B to teach their children about the kno wledge of failure.C to provide their children with the knowledge against failure.D to keep their children from realizing that they failed.(5)According to the passage,if you are facing failure,you should________A blame someone else.B face it yourself and not ask others for help.C forget it as s oon as possible.D think it over and find ways to improve it.18. It feels like every time my mother and I start to have a conversation, it turns into an arg ument.We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War III.She'll talk about my lack of a bright future because I don't plan to be a doctor.And much to her disappointment, I don't want to do any job relate d to science, either.In fact, when I was pushed to say that I planned to major(主修) in English and communications, she nearly had a heart attack."Why can't you be like my co-worker's son? "she bemoans all the time.Her co-worker's son received a four-year scholarship and is now earning 70, 000dollars a year as an engineer.I don't know wha t to answer except that I simply can't be like Mr.Perfect as I've called the unnamed co-worker's son.I can't be like him.I'm the type of person who loves to help out in the comm unity, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名声) or salary.I understand why my mother is worried about my future major.I've seen my mother stru ggle to raise me on her small salary and work long hours.She leaves the house around 6: 30 am and usually comes home around 5pm or even 6pm.However, I want her to know that by becoming a doctor, it doesn't mean I'll be successful.I'd rather follow my dreams and creat e my own future.(1)Which of the following topics do the writer and his mother often talk about?________ A The writer's studies. B The writer's future job. C Dinner plans. D Wars aro und the world.(2)We can infer from Paragraph 1that the writer's mother________.A doesn't want the writer to major in English.B doesn't think the writer should be a d octor.C gets along very well with the writer.D doesn't think working in the scien ce field is a good idea.(3)The underlined word"bemoans"in Paragraph 2most probably means________.A agrees.B shouts.C complains.D smiles.(4)Which of following statements is probable TRUE ab; out the writer?________A He wants to be like his mother's co-worker's son. B He wants to find a job in his community in the future. C He doesn 't think his mother's co-worker's son is perfect. D He wants to do so something he really likes in the future.(5)We can know from the last paragraph that________19. A British judge ruled recently that swearing (咒骂) at the police is not a crime (犯罪), setting off a heated debate(辩论) across the nation.Denzel Cassiues Harvey, 19, was stopped outside his home in Hackney, East London, by pol ice officers who thought he was carrying drugs.He was fined£50by a count for repeatedly (重复)swearing at the police who were searching him for drugs.But judge David Bean overturned(推翻) the decision of the previous(以前的) court.He said that police officers hear foul language too frequently to be offended (冒犯).Judge David Bean said the foul language used by Harvey was unlikely to cause the polic e officers harm, alarm or distress(苦恼), because it was so"common".The judge may have been right to cancel(取消) the fine in this individual case.But there are massive problems with what he said whe n making the ruling.Foul language is frequently directed at police officers, but this doesn't mean that it should be accepted as part of their working life.How can we justify(证明) this? There are the people who devote their lives to protecting us.What does it say about our respect for the police, if we see them as people who can be spok en to abusively (粗暴地) without a second thought?There are many times that police officers do not penalize member of the public for swearin g at them and it would be impractical(不切实际的) to punish every person that abuses (辱骂) them with foul language.But if officers feel that someone has crossed the line, they should not be criticized for react ing(反应) to this.They are there to make these judgement and we need to allow them to do so. The question is not what is said, but how the language is used.If a person swears with ge nuine(真实的) aggression (进攻,侵犯)and aims to cause fear they should be penalized.The police are enforcers (实施者)of the law, not mute(无声的) punch bags.(沙袋)(1)Why was Denzel Cassiues Harvey stopped by police officers?________A Because he was carrying drugs in his pocket.B Because the police suspected that he was carrying drugs.C Because he swore at police officers on duty.D Because he was a wanted criminal.(2)What do you know about David Bean?________A He is 19years old.B He offended police officers.C He canceled the£50fine. D He was a police officer.(3)What does the writer think of Judge David Bean's ruling?________A He disapproves of David Bean's ruling.B He thinks it right for Judge David Bean to ca ncel the fine.C He thinks Judge David Bean's ruling sounded reasonable.D He thi nks highly of David Bean's ruling.(4)What does the underlined word"penalize"mean?________A Offend.B Abuse.C Criticize.D Punish.(5)Which of the following is the best title?________A Law needs to protect the police,too. B Swearing at the police should be banned. C Denzel Cassiues Harvey's case set off a heated debate. D Judges are supposed to support the police.20. What exactly is a lie? Is it anything we say which we know is untrue? Or is it something more than that? For example, suppose a friend wants to borrow some money from you.You say"I wish I could help you, but I am short of money myself."In fact, you are not short of mo ney but your friend is in the habit of not paying his debts and you don't want to hurt his feeli ngs by reminding him of this.Is this really a lie?Professor Jerald Jellison of the University of southern California has made a scientific study of lying.According to him, women are better liars than men, particularly when telling a"wh ite lie", such as when a woman at a party tells another woman that she likes her dress when s he really thinks it's terrible.However, this is only one side of the story.Other researchers s ay that men are more likely to tell more serious lies, such as making a promise that they have no intention of carrying out.This is the kind of lie politicians and businessmen are suppose d to be particularly skilled at: the lie from which the liar hopes to profit or gain in some way. Research has been done into the way people's behavior changes in a number of small, uni mportant ways when they lie.It has been found that if they are sitting down at the time, they tend to move about in their chairs more than usual.To the trained observer they are sayin g"I wish I were somewhere else now".They also tend to touch certain parts of the face, part icularly the nose.One explanation of this may be that lying causes a slight increase in blood pressure.The tip of the nose is very sensitive to changes and the increased pressure makes it itch.Another gesture that gives liars away is what the writer Decmond Morris in his book Man Watching calls the"mouth cover".He says that there are several typical forms of this, such as covering part of the mouth with the fingers, touching the upper lip or putting a finger of the hand at one side off the mouth.Such a gesture can be understood as an unconscious(未察觉的) attempt on the part of the liar to stop himself from lying.Of course, such gestures as rubbing the nose or covering the mouth, moving about in a chai r can not be taken as proof that the speaker is lying.They simply tend to happen more often in this situation.It is one gesture alone that gives the liar away but a whole number of thing s, and in particular the context(上下文) which the lie is told.(1)According to the passage,a white lie seems to be a lie________.A that other people believe.B that other people don't believe.C told in order not to hurt someone's feelings.D told in order to take advantage of someone.(2)Research suggests that women________.A are better at telling less serious lies than men.B generally lie for more than men do .C often make promises they intend to break.D lie at parties more often than men do.(3)Researchers find that when a person tells lies________.A his blood pressure increases measurably.B he looks very serious.C he is likely to make some small changes in his behavior.D he uses his unconscious mind.(4)The writer of the passage________.A hates lying.B enjoys lying.C often tells a lie.D tries to study about lying.(5)Which of the following is not mentioned in the passage as a sign of lying?________A Touching one's ears.B Rubbing the nose.C Moving in a chair.D Covering the mouth.四.英语改错题(10分,每小题0.5分)21. 下面短文中分别有10处语言错误.请在错误的地方作出记号,增加,删除或修改某个单词.写在横线上.We are all busy talking about and use the Internet which set up many years ago.At first,the internet was only used by the government,but in the early 1970s',universities,hospitals and banks were allowed to use it as well as.However,computers were still expensive and the Internet was difficult to use it.Thirty years later,computers become cheaper and easier.Today it is easy to get on line and it is told that milli ons people use the Internet every day.Send e-mail is more and more popular between students.It has become one of the most important parts of people's life.56.________57.________58.________59.________60.________61.________62.________63._____ ___64.________65.________.22.

(a为常数,a>0)(1)当a=1时,求函数f(x)在x=1处的切线方程;(2)当y=f(x)在x=处取得极值时,若关于x的方程f(x)﹣b=0在[0,2]上恰有两个不相等的实数根,求实数b的取值范围;(3)若对任意的a∈(1,2),总存在x0∈[,1],使不等式f(x0)>m(a2+2a﹣3)成立,求实数m的取值范围.考点:利用导数研究曲线上某点切线方程;函数的零点与方程根的关系;其他不等式的解法.专题:综合题;导数的综合应用.分析:(1)a=1时求出f′(x),则切线斜率k=f′(1),求出切点,利用点斜式即可求得切线方程;(2)求导数f′(x),令f′()=0可得a,利用导数可求得函数f(x)在[0,2]上的最小值、最大值,结合图象可知只需满足直线y=b与y=f(x)的图象有两个交点即可;(3)先利用导数求出f(x)在[,1]上的最大值f(1)=ln()+1﹣a,则问题等价于对任意的a∈(1,2),不等式ln()+1﹣a﹣m(a2+2a﹣3)成立,然后利用导数研究不等式左边的最小值即可;解解:(1)a=1时,,答:∴,于是,又f(1)=0,即切点为(1,0),∴切线方程为;(2),,即a2﹣a﹣2=0,∵a>0,∴a=2,此时,,∴上递减,上递增,又,∴;(3)f′(x)=+2x﹣a==,∵1<a<2,∴=<0,即,∴f(x)在[,2]上递增,∴f(x)max=f(1)=ln()+1﹣a,问题等价于对任意的a∈(1,2),不等式ln()+1﹣a>m(a2+2a﹣3)成立,设h(a)=ln(+a)+1﹣a﹣m(a2+2a﹣3)(1<a<2),则h′(a)=﹣1﹣2ma﹣2m=,又h(1)=0,∴h(a)在1右侧需先增,∴h′(1)≥0,m≤﹣,设g(a)=﹣2ma2﹣(4m+1)a﹣2m,对称轴a=﹣1﹣≤1,又﹣2m>0,g(1)=﹣8m﹣1≥0,所以在(1,2)上,g(a)>0,即h′(a)>0,∴h(a)在(1,2)上单调递增,h(a)>h(1)=0,即ln()+1﹣a>m(a2+2a ﹣3),于是,对任意的a∈(1,2),总存在x0∈[,1],使不等式f(x0)>m(a2+2a﹣3)成立,m.点评:本题考查导数的几何意义、利用导数研究函数的极值、最值,考查函数恒成立问题,考查函数与方程思想、分类讨论思想,综合性强,难度大.。
