A＝2t﹣6，由于点P在第四象限，纵坐标小于0，则P（6，6﹣2t）．③当7≤t≤10时，点P在BC上，此时PB＝2t﹣OA﹣AB＝2t﹣14，PC＝BC﹣PB＝6﹣（2t﹣14）＝20﹣2t．∴P（20﹣2t，﹣8）．（3）当点P在线段AB上时，分两种情况：①如图3中，结论：∠PEA+∠PFC＝160°，理由如下：连接OP，∵∠PFC＝∠FPO+∠FOP，∠AEP＝∠EOP+∠EPO，∴∠PEA+∠PFC＝∠FPO+∠FOP+∠EOP+∠EPO＝∠AOF+∠EPF＝90°+70°＝160°；②如图4中，结论：∠PFC﹣∠AEP＝20°，理由如下：设PM交OC于G，∵∠AEP+∠EGO＝90°，∠EGO＝∠PGF＝110°﹣∠PFC，∴∠AEP+110°﹣∠PFC＝90°，∴∠PFC﹣∠AEP＝20°，综上所述，∠PFC+∠PEA＝160°或∠PFC﹣∠AEP＝20°．26．解：（1）∵A（0，3），B（，0），∴AB＝2 ，∵点C1（0，3+2 ），∴AC1＝3+2﹣3＝2，∴AC1＝AB，∴C1是线段AB的“等长点”，∵点C2（﹣，0），∴AC2＝＝2，∴AC2＝AB，∴C2是线段AB的“等长点”，∵点C3（0，﹣），∴BC3＝，∴BC3≠AB，∴C3不是线段AB的“等长点”；故答案为：C1，C2；（2）如图，在Rt△AOB中，OA＝3，OB＝，∴AB＝2 ，∴∠OAB＝30°，当点D在y轴左侧时，∵∠DAB＝60°，∴∠DAO＝∠DAB﹣∠BAO＝30°，∵点D（m，n）是线段AB的“等长点”，∴AD＝AB，∴D（﹣，0），∴m＝，n＝0，当点D在y轴右侧时，∵∠DAB＝60°，∴∠DAO＝∠BAO+∠DAB＝90°，∴n＝3，∵点D（m，n）是线段AB的“等长点”，∴AD＝AB＝2 ，∴m＝2，综上，m＝，n＝0或m＝2，n＝3．。

南京市2024届高三年级考前综合训练题( 二)英语2024.05第二部分阅读(共两节，满分50分)第一节(共15小题; 每小题2.5分，满分37.5分)阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
For centuries, the “Big Four” diamonds, red stones, green stones and blue stones—ruled the gem (珠宝) world. When tanzanite first appeared in 1967, it became a hit. Unlike those other stones, which are mined all over the world, tanzanite can be found in only one place on Earth: in the remote Merelani Hills in the shadow of Mt. Kilimanjaro in Tanzania, Africa.Gem of the century meets deal of the century. With its remarkable rarity and unique gemstone qualities, it’s no wonder that experts have called it “the gemstone of the 20th century”. In recent years, top-quality tanzanite gems have fetch ed higher prices at auction (拍卖会) than the Big Four! But because we buy direct and use our own designers, we are able to offer you this rare beauty for ONL Y $59!What makes tanzanite so ir resistible to gem experts? Part of its appeal is the beautiful violet blu e color. Tanzanite is also trichroic—which means that three different colors are visible when the stone is viewed from different angles.A gemstone found in only one place on earth means supply is extremely limited. Get your hands on the Karatu Tanzanite Ring before they’re gone!Your satisfaction is 100% guaranteed. Experience the rare beauty of the Karatu Tanzanite Ring for two months. If you’re not completely impressed, simply send it back within 60 days for a complete return of the sale price. We want you to feel like you got the deal of the century!21. What is tanzanite?A. A ring brand.B. A kind of stone.C. A place in Africa.D. A deal of the century.22. What is special about tanzanite?A. Its bright color.B. Its high price.C. Its long-standing reputation.D. Its unique place of origin.23. What is the purpose of the text?A. To promote goods.B. To introduce a gem.C. To present a discovery.D. To recommend return service.BRepositioning the light for the third time, Reilly leaned (倾斜) the phone at an angle she thought would make her face look skinny. She prepared herself for her best smile in3,2, 1!Finally! A picture she can work with. Everyone else in school had a social media account and nobody knows how hard she tried to eve ntually get mom’s permi ssion. She had been sitting up her account for days, and the picture of herself was the final touch.She had worked cautiously creating her profile. Her hometown was boring, so she filled in a more exciting one several towns over. Her job was nonexistent since she was only 14, but she filled in “Accountant”. Why not? Seemed like a cool job. And she was getting good at making a perfect account here, so “accountant” was fitting.She wrote her first post. Then deleted it. She wanted to avoid sounding like she just started an account. She thought of something brilliant.“Hey new account here, had to. You know, locked out of my other one. Add me here!”Now people would think she had to start this one because an old one got hacked (非法入侵)，and they just didn’t know she had none before. Then the “friend spread” would happen. The website would start suggesting her page to friends of friends until she grew her list to a respectable size.It was starting already! Friend requests on her list. A comment! “Gorgeous (漂亮的) girl!” It was from Amy, in her science class. Reilly felt gorgeous.At school, Reilly looked around wondering who saw her new profile.“Hey. Saw your new account,” Nora, her best friend, said from somewhere behind her.“How does it look?” Reilly asked.“It looks pretty cool. But, I almost didn’t know it was you, Reilly,” Nora smiled. “And just in case you forget, you are good enough as you are.”24. What was Reilly busy doing these days?A. Looking for a cool jotB. Chatting with friends online.C. Setting up a social media account.D. Improving her photography skills.25. Why did Reilly rewrite her post?A. To sound more experienced.B. To add something brilliant.C. To unlock her old account.D. To ensure safety of her page.26. What did Reilly feel gorgeous about?A. Making a new friend in real life.B. Having a science lesson with Amy.C. Creating a profile totally on her own.D. Expanding her influence on social media.27. What does Nora’s comment imply?A. Reilly should appreciate her true self.B. Reilly should pursue the best version of herself.C. Reilly shouldn't be too proud of what she's done.D. Reilly shouldn't forget to show the good side of her.CA new network of dedicated antennas (天线) in Africa will lend insight into the damage that storms of charged particles (粒子) from the sun make on satellite and radio communications. Zambia set up its first such sensor in March —one of eight multifrequency receivers being stationed around Africa, in addition to four already operating in South Africa. Kenya and Nigeria will set up their receivers by the end of the year.The Space Weather network that extends over Africa will provide real-time data on how solar storms distort (扭曲) the ionosphere, the charged outer layer of Earth's atmosphere. This distortion can have dangerous consequences, says Mpho Tshisaphungo, a space weather researcher at the South African National Space Agency (SANSA). Signals between crucial satellites and the ground pass through this region, where charged particles can cause interference (干扰). Also, high-frequency radio signals (often used in defense and emergency services communications) have to bounce off the ionosphere; Tshisaphungo notes that when solar storms change the layer, “the radio signal may eithe r be weakened, delayed or absorbed by the iono sphere.”“While there are data available from international space weather programs, if you want to look at what’s happening on the African continent, then you need to take measurements in Africa,” says John Habarulema, a space scientist at SANSA. Habarulema’s team developed a model last year that maps electron density (电子密度) in the ionosphere and fills in measurement gaps. The new local receivers will boost this model's accuracy and let it describe fluctuations (波动) over the full continent. “We need to have the global perspective and put that data into our global models,” says Terry Onsager, a U.S. physicist. “But at the same time, space weather disturbances can vary enormously from location to location.” And it is becoming increasingly important to model the ionosphere’s behavior, he says, because “we’re getting more and more reliant on techmologies that are reliant on space weather.”28. What is the function of the newly-set antennas in Africa?A. To prevent possible distortion of the ionosphere.B. To analyse the weather changing records of the region.C. To improve internet connectivity in African rural areas.D. To monitor solar storms’ effects on radio communications.29. Which of the following is a “dangerous consequence” according to paragraph 2?A. Satellites may be destroyed.B. Crucial signals may be blocked.C. Bad weather may strike the earth.D. Charged particles may be weakened.30. What is paragraph 3 mainly about?A. The development of global weather models.B. The factors of accurate space measurement.C. The importance of collecting global climate data.D. The necessity of building multi frequency receivers in Africa.31. What is the best title for the text?A. The sun takes people on earth by stormB. Joint efforts in need to deal with solar stormsC. New space weather network extends over AfricaD. Africa on board to protect radio communicationsDHow could anyone dislike giving and receiving gifts? A good gift can be totally life changing. Gifts are so meaningful that some people identify “receiving gifts” as their primary“love language”.Indeed, on the surface, gift-giving occasions seem like wonderful opportunities to experience and create delight. But according to a 2023 survey, gift-giving and receiving is actually the least popular love language overall.The problem is that occasions that involve gift giving are full of uncertainty. If it’s an occasion like Christmas, where people are shopping for each other at the same time, people might still be nervous about whether the gift they give will be in the same category as the gift they will also receive. For instance, you don’t want to give someone a gag (恶作剧) gift when they're giving you a sincere, heartfelt gift. Mismatched approaches to gift-giving are a common recipe for awkwardness.There can also be enormous uncertainty around how your gift will be experienced by the receiver. Imagine that a close friend is showing some signs of seasonal affective disorder, and you’re giving him a therapy (疔法) lamp as a gift. True, he may very well be appreciative, indicating that this is “just what he needed.” But what if he interprets the gift as an unwelcome piece of commentary on his affective state? One could imagine a reaction along the lines of “Gosh, I’m sorry I’ve been so unpleasant to be around,” The message we send is not necessarily the same as the message received.Worst of all, there’s the anxiety that comes with receiving gifts. If you are like me, you may have found yourself in a setting where you expect a lot of well-meaning but disappointing gifts are headed your way. There can be some fear that comes with knowing that you'll soon need to perform joy and appreciation. Even worse, you might worry that the gift-giver will detect your in sincerity, wounding them in the process.It's not all bad, of course. When done carefully, gift-giving can be a wonderful way to draw people closer together, in a lasting way.32. Gift giving is full of uncertainty because ______.A. people prepare insincere gifts for othersB. the gifts they give are of the same categoryC. people shop for gifts for different occasionsD. mismatched gift- giving frequently happens33. An example of the therapy lamp is used to illustrate ______.A. trust can be earned through gift-givingB. misunderstanding can arise from gift-givingC. harmony can be achieved through gift-givingD. depression can be a byproduct of gift-giving34. What makes a gift-receiver most anxious?A. Expressing disappointment over the gifts.B. Having pretended delight at the gifts uncovered.C. Expecting well-intentioned gifts from friends.D. Fearing to extend appreciation for the gifts.35. What is the author’s at titude towards gift giving?A. Supportive.B. Opposed.C. Objective.D. Unclear.第二节(共5小题;每小题2.5分，满分12.5分)阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

该三倍体开花后授以纯合二倍体红瓤西瓜花粉，则所结无子西瓜瓜瓤的颜色和基因型分别为()A．红瓤，Rrr B．红瓤，RRrC．红瓤，RRR D．黄瓤，rrr解析：选A。
考查三倍体无子西瓜的培育。
四倍体的母本基因型是rrrr，与RR杂交后其三倍体的后代基因型为Rrr，该三倍体作母本，所结果实的果皮基因型和表现型均和亲本相同。
2.在美国《国家科学院院刊》2009年7月15日发表的一项研究中，来自美国北卡罗来纳州立大学和杜克大学的科学家发现，有性生殖的月见草比同科无性生殖的植株能更好的抵御食草昆虫的侵害，科学家认为，有性生殖会使基因混合，这样个体植株就可以去掉一些不好的基因，保留好的基因，这有助于他们不断发展新的方法以抵御虫害，下列有关叙述中错误的是()A．有性生殖可增加遗传物质重组的机会B．进行有性生殖的后代个体具有双亲的遗传性，有更大的变异性和生活力C．在有性生殖过程中可能会发生交叉互换现象D．有性生殖可保持亲、子代遗传性状的一致解析：选D。
由“有性生殖会使基因混合，这样个体植株就可以去掉一些不好的基因，保留好的基因，这有助于他们不断发展新的方法以抵御虫害”可知选项A、B正确；在有性生殖形成配子过程中，减数第一次分裂前期同源染色体会出现联会现象，可能会发生同源染色体的交叉互换，所以C选项正确；有性生殖继承了双亲的遗传物质，但非同源染色体发生了自由组合，所以亲子代之间既有相似性也有差别，故选项D错误。

WritingFor Better Understanding between Parents and ChildrenWith a steep rise in numbers of children who leave their kith and kin, the problem oflacking of understanding between parents and children has aroused general concern in recent years. And better understanding between the two generations is called for in society.So what causes this situation? First, it comes from the generation gap. Growing in different times leads to great difference in interests between the two generations. For example, R&B, about which many teenagers are crazy, is decadent music in their parents eyes. And meanwhile, teenagers can t stand the boredom and dullness in their parents life. Second, the reason is the lack of communication. Nowadays, parents slave to earn money and spend less time to talk with their children. And the children think it just an excuse of not concerning about them. Third, the reason is the pressure. As most children are from only child families, their parents baby them, hoping they will be successful in the future. But in fact, the pressure makeschildren depressed and heedless of advice. To solve this problem, efforts should be made by both sides: For parents, they should try to listen to their children with patience to find out what they really want; and for children, they just remember that what their parents do is all for their sake. And then the conversation between parents and children will be much easier and better understanding can be available.Ⅱ.

WritingMy View on Going after Fashion Nowadays, some college students like to go after fashion. Boy students wear long hair and blue jeans and girl students wear short hair and mini shirts. Whenever a new fashion appears on the street, these young people will just follow it without considering whether it is suitable to them or not. In their eyes, fashionis the symbol of the young generation. However, some other students prefer to go their own way. They pay little attention to the common taste of fashion. They often seek the styles they really like. Though sometimes what they wear is quite different from others, they do look great and nice.As to me, I don t like to go after fashion. Though fashion, in some way, may show a tendency of common taste, it depersonalizes people by making people everywhere look alike. I think only those who lack confidence will try to show their existence by these outside presentation. As college students, we should find ourselves and be ourselves. That will be the only kind of fashion that really counts.Ⅱ. Reading Comprehension(Skimming and Scanning)1-7 CBCBADC8. the educational under achievement9. working with the family10.

WritingOn StressWith the fast pace of modern life, more and more people are living under great pressure. Some people are afraid of pressure. They think that the stresses and strains of work deprive them of joy and happiness. In their view, stress does harm to them both physically and mentally. That is why they prefer something less competitive and strenuous to something more demanding and challenging.Others argue that stress isn t as bad as it is often supposed to be. Unless it is overwhelming, a certain amount of stress is vital to provide motivation and stimulation. Without stress, you may slack off and idle away your time. It gives purpose and meaningto an otherwise meaningless, dull life. People under stress tend to bring their potential into full play and to realize their goals.In my opinion, we shouldn t escape from stress but to face it as it is. What we can do is to adapt to the stress and to profit from it rather than to avoid it.Ⅱ.

WritingThe Value of TimeA proverb says, “Time is money.” But in my opi nion, time is even more precious than money. Why? Because when money is spent, we can earn it back. However, when time is gone, it will never return. This is the reason why we must value time.It goes without saying that the time for our study and work is unusually limited. Hence, even an hour is extremely precious. We should make full use of our time to do useful things. As a student, I must make efforts to engage in my study so as to serve our nation and people in the future. But it is a pity that there are a lot of people who do not know the importance of time. They do not realize that wasting time is equal to wasting a part of their valuable life.In a word, we should form the good habit of saving time. Do not put off what can be done today till tomorrow. Laziness will not only bring us failure but also lead us to the road of poverty.Ⅱ.

WritingGreen OlympicsOlympic Games, as we all know, is a historic sports meeting. “Green Olympics”, is one of the three themes of 2008 Beijing Olympic Games. At present, people s life is being flooded with exhaust gas from automobile, waste water from factories and so on. Owing to these phenomena, we should advocate “Green Olympics”, and I am positive of this point.Two possible reasons are as follows. Firstly, environmental protection benefits people s health. In terms of increasing number of trashes around us, such as white plastic bags, one off cups and chopsticks, it is sensible of disposing of them reasonably. So we ought to use clean technology, renewable and recyclable materials. Secondly, environmental protection is crucial to our country, and even to the world. In recent years, natural disasters, like tsunami in $2 and snowstorms in $2, are partly due to the disturbance of the environmental balance.In conclusion, as college students and the young generation, we should try our best to advocate “Green Olympics”. The 2008 Olympic Games should be a green and unique Olympics.Ⅱ. Reading Comprehension(Skimming and Scanning)1-7 BCDACDC8. $29. poems10. reindeer(with a disturbing red nose)Ⅲ.

WritingThe Heavy Burden of StudyNowadays, we often hear students complaining about the ever increasing pressure of their studies. The school bags on their backs are getting heavier and heavier, the hours spent on their assignments (are) longer and longer, and the after class activities (are) few and far between. The reasons for such a heavy burden, however, are various. On the one hand, parents have a strong desire for the early intellectual achievement of their children, thus, forcing them to read more and work harder. On the other hand, all teachers wish their students academic records better than others, because it is the main criterion to evaluate their work, so that they assign more exercises and homework for their students to do after class.We should take measures to solve this problem. First, the existing testing system should be reformed. Second, more attention should be paid to the development of personal quality and overall abilities instead of mere score on the examination papers. Only by doing these can we relieve students burden of study.Ⅱ.

WritingCompetitionCompetition makes people more creative and effective. It urges them to plan better, to try harder, and to achieve more. With a desire to excel in their work, people tend to perform more creatively and more efficiently.Competition helps produce better products and provide better services. In the present world of intense competition, every manufacture tries his best to outmatch his competitor by producing goods of better quality at lower costs. As a result, consumers pay less and receive better service. Competition promotes further development of society. If there were no competition, people would remain complacent and be unwilling to make any efforts or risk anything new. However, with fierce competition going on, they exert themselves to accomplish more. Their accomplishment will, in one way or another, contribute to the progress of society.Ⅱ.

WritingFor Better Understanding between Parents and ChildrenWith a steep rise in numbers of children who leave their kith and kin, the problem of lacking of understanding between parents and children has aroused general concern in recent years. And better understanding between the two generations is called for in society.So what causes this situation? First, it comes from the generation gap. Growing in different times leads to great difference in interests between the two generations. For example, R&B, about whichmany teenagers are crazy, is decadent music in their parents eyes. And meanwhile, teenagers can t stand the boredom and dullness in their parents life. Second, the reason is the lack of communication. Nowadays, parents slave to earn money and spend less time to talk with their children. And the children think it just an excuse of not concerning about them. Third, the reason is the pressure. As most children are from only child families, their parents baby them, hoping they will be successful in the future. But in fact, the pressure makes children depressed and heedless of advice.To solve this problem, efforts should be made by both sides: For parents, they should try to listen to their children with patience to find out what they really want; and for children, they just remember that what their parents do is all for their sake. And then the conversation between parents and children will be much easier and better understanding can be available.Ⅱ.

WritingMy View on Going after FashionNowadays, some college students like to go after fashion. Boy students wear long hair and blue jeans and girl students wear short hair and mini shirts. Whenever a new fashion appears on the street, these young people will just follow it without considering whether it is suitable to them or not. In their eyes, fashion is the symbol of the young generation.However, some other students prefer to go their own way. They pay little attention to the common taste of fashion. They often seek the styles they really like. Though sometimes what they wear is quite different from others, they do look great and nice.As to me, I don t like to go after fashion. Though fashion, in some way, may show a tendency of common taste, it depersonalizes people by making people everywhere look alike. I think only those who lack confidence will try to show their existence by these outside presentation. As college students, we should find ourselves and be ourselves. That will be the only kind of fashion that really counts.Ⅱ. Reading Comprehension(Skimming and Scanning)1-7 CBCBADC8. the educational under achievement9. working with the family10.

WritingOn StressWith the fast pace of modern life, more and more people are living under great pressure. Some people are afraid of pressure. They think that the stresses and strains of work deprive them of joy and happiness. In their view, stress does harm to them both physically and mentally. That is why they prefer something less competitive and strenuous to something more demanding and challenging.Others argue that stress isn t as bad as it is often supposed to be. Unless it is overwhelming, a certain amount of stress is vital to provide motivation and stimulation. Without stress, you may slack off and idle away your time. It gives purpose and meaning to an otherwise meaningless, dull life. People under stress tend to bring their potential into full play and to realize their goals.In my opinion, we shouldn t escape from stress but to face it as it is. What we can do is to adapt to the stress and to profit from it rather than to avoid it.Ⅱ.

WritingAdvantages of a Job InterviewNowadays, when a person is hunting for a job, there will always be a job interview and I think the job interview has a lot of advantages. The interviewer and the interviewee can know about each other from it.First, the interviewer can tell something about the job to the interviewee such as the salary, the working conditions and something else that is relevant to the job. Then the interviewee can decide whether the job is really suitable for him. Second, I think the job interview is a good chance for the interviewee to show both his ability and confidence. Then the interviewer can figure out whether he is the right person for the job.In a word, I think the interview will do good to both the interviewer and the interviewee.

WritingNo Pains, No GainsNearly every civilization has its own equivalent to the proverb “No pains, no gains.” It means that nothing can be gained without painstaking efforts and that no knowledge or skill can be acquired without sweat or toil.You don t have to look very far to prove the truth of the proverb. Darwin s great discovery was not the work of a moment but was preceded by years of patient, arduous observation. Mozart was not an accomplished pianist at the age of eight as the result of watching countless hours of TV. Nor did $2 make himself the greatest inventor in the modern world by spending his spare time on going to parties or bars. His words “Genius is 99 percent perspiration and one percent inspiration” reveals the secret of thousands of successful men and women. All accomplishments and success come from sustained endeavor.Although it is an old saying,“No pains，no gains” has its profound and realistic significance in our college studies. To acquire knowledge in a particular field and to attain any academic goals, great exertion and persistent effort are undoubtedly required because we all know that “No pains, no gains.”Ⅱ.

WritingInformation SecurityThe human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick playing teens, exploring children, fraudsters, and serious white collar criminals. Thus, information security becomes an impending important issue.In case of information breach, the victims—government departments, organizations or institutions, or companies will inevitably suffer great or small loss. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public s and users confidence will be damaged.Then how to deal with this issue? Technology is only a partial solution to information security. What s more important is that organizations and companies should promote the awareness on information security to its staff. However, since no system can ever be 100 percent secure, a prevention only approach to information security management is not enough. Companies and organizations should adopt a dual approach to information security management by combing prevention and detection techniques.Ⅱ.

附《晁错》翻译：
晁错是颖川人。
曾经在轵县张恢先生那里学习过申不害和商鞅的刑名学说，与洛阳人宋孟和刘礼是同学。
凭着通晓典籍，担任了太常掌故。
晁错为人严峻刚正，却又苛刻严酷。
孝文帝的时候，天下没有研究《尚书》的人，只听说济南伏先生是原来秦朝的博士，研究过《尚书》，年纪已经九十多岁，因为太老无法征召他来，文帝于是下令太常派人前往学习。
太常派遣晁错前往伏先生那里学习《尚书》。
学成回来后，趁着向皇上报告利国利民的事，称引解说《尚书》。
汉文帝下诏令，任命晁错担任太子舍人、门大夫、太子家令。
晁错凭着他的辩才，得到太子的宠幸，太子家称他为“智囊”。
汉文帝的时候，晁错多次上书，说到削减诸侯势力的事，以及修改法令的事。
几十次上书，汉文帝都没有采纳，但认为他有奇特的才能，提升为中大夫。
当时，太子称赞晁错的计策谋略，袁盎和诸位大功臣却大多都不喜欢晁错。
汉景帝继位后，任命晁错为内史。
晁错多次请求皇帝单独与他谈论政事，景帝每每都听，宠幸他超过了九卿，晁错修改了不少的法令。
丞相申屠嘉心里不满意，但又没有足够的力量来毁伤他。
内史府建在太上庙围墙里的空地上，门朝东，出入很不方便，晁错便向南边开了两个门出入，因而凿开了太上庙的围墙。
丞相申屠嘉听到了这件事，非常生气，打算就这次晁错的过失写成奏章，请求诛杀晁错。
晁错听到了这个消息，当夜请求单独进谏皇上，具体详细地向皇上说明了这件事情。
丞相申屠嘉上朝奏事，乘机禀告了晁错擅自凿开太上庙的围墙做门，请求皇上把他交给廷尉处死。
皇上说:“晁错所凿的墙不是大上庙的墙，而是庙外空地上的围墙，不致于触犯法令。
”丞相谢罪。
退朝之后，生气地对长史说:“我本当先杀了他再报告皇上。
却先奏请，反而被这小子给出卖，实在是大错。
”丞相终于发病死了。
晁错因此更加显贵。
晁错被提升为御史大夫，请求就诸侯的罪过相应地削减他们的封地，收回各诸侯国边境的郡城。
奏章呈送上去，皇上命令公卿、列侯和皇族一起讨论，没有一个人敢非难晁错的建议，只有窦婴与他争辩，因此和晁错有了隔阂。
晁错所修改的法令有三十章，诸侯们都叫喊着反对，痛恨晁错。
晁错的父亲听到了这个消息，就从颖川赶来，对晁错说:“皇上刚刚继位，你执掌政权，侵害削弱诸侯的力量，疏远人家的骨肉，人们纷纷议论怨恨你，为什么要这样做呢？”晃错说:“事情本来就应该这样，不这样的话，天子不会受到尊崇，国家不会得到安宁。
”晃错的父亲又说:“照这样下去，刘家的天下安宁了，而我们晁家却危险了，我要离开你回去了。
”便服毒药而死，死前说道:“我不忍心看到祸患连累自己。
”晃错的父亲死后十几天，吴楚七国果然反叛，以诛杀晁错为名义。
等到窦婴、袁盎进言，皇上就命令晁错穿着朝服，在东市把他处死。
（晁错死后，谒者仆射邓公担任校尉，攻打吴楚的军队时，他担任将领。
回京城后，上书报告军事情况，进谏皇上。
皇上问道:“你从军中来，听到晁错死了，吴楚的军队退了没有？”邓公说:“吴王蓄意谋反已经有几十年了啊，他为你削减他的封地而发怒，所以以诛杀晁错为名义，他的本意并不在晃错呀。
再说我担心天下的人从此都将闭口，再也不敢进言了。
”皇上说:“为什么呢？”邓公说:“晁错担心诸侯强大了不能够制服，所以请求削减诸侯的封地，借以尊宠朝廷，这实在是关乎万世的好事啊。
计划才开始实行，突然遭到杀戮，对内堵塞了忠臣的口，对外反而替诸侯报了仇，我私下认为陛下这样做是不足取的。
”此时景帝沉默了好久，说:“您的话很对，我也悔恨这件事。
”于是任命邓公担任城阳中尉。
