Should Smoking Be Completely BannedPart II Reading Comprehension (Skimming and Scanning)(15 minutes)Directions: In this part, you will have 15 minutes to go over the passage quicklyand answer the questions on Answer Sheet 1.For questions 1-7,choose the best answer from the four choices marked [A],[B],[C]and [D]. For questions 8-10,completethe sentences with the information given in the passage.Space Our Future in Space: It Has Already Begun!We are all space travelers. But we’ve stayed close to home until now. One day,we may leave our “mother ship”Earth to make our home among the stars.A giant, spherical “spaceship”, about 8,000 miles in diameter, is speedingthrough the solar system right now. It is cruising at an incredible 66,600 milesper hour.It’s not a giant, Star Wars mother ship. It’s spaceship Earth, the home ofover four billion people. This water coated spaceship has been traveling throughthe universe for about five billion years. Only within the past 25 years, however,have some of its passengers broken free of Earth’s gravityBut 25 years from now, many people, including you, might live in an orbitingspace station 200 miles above the Earth.Space CitiesScientists have already designed special space factories. These factories will take advantage of the absence of gravity (zero gravity) to produce everything from life saving drugs to perfect ball bearings.Other scientists have designed space colonies, complete with farms, schools,and artificial day and night. Hundreds, or even thousands, of people will live, work,play—even go toschool, far above the Earth.Our conquest of space, of course, has already begun. We have explored part of the Moon, sent robot spaceships onto the surface of Venus and Mars, and aimed space probes past the planets of Jupiter and Saturn.Last June, one robot ship, Pioneer 10, left our solar system forever. Andastronauts from both the Soviet Union and the United States have lived in spacestations.The conquest of space, without question, is one of the greatest adventures human beings have ever set out on. But it may be more than a great adventure. Some scientiststhink the conquest of space may be a necessity for survival of the human species.We are tearing up more and more of the Earth to get raw materials for industry.And we are polluting the air and water as we manufacture products that we need or want. Almost everything that seems to make our lives more comfortable, and fromelectricity to pesticides, uses up or alters a piece of our planet’s natural environment.Why Go into Space?Yet our solar system is full of resources. The moon is chockfull of valuable metals. So are the asteroids, the small, rocky, planet like bodies orbiting the sun most of them between Mars and Jupiter. These metals, if we can get them, could be used to build factories and space stations.Also, in space, there is no atmosphere to filter out the sun’s energy. There is plenty of solar energy to be turned into electricity for manufacturing, for creating comfortable living conditions.Getting away from Earth has other advantages, too. Modern industry uses manykinds of metal alloys (mixtures of metal thatare better for certain purposes thanpure metals). Yet some metal alloys either can’t be made or are very expensive to make on Earth because of gravity. For instance, certain metals don’t mix well onEarth. But in zero gravity, molten (hot, liquid) metals mix more evenly. This is because there is no gravity to pull the heavier metals down, while the lighter ones float on top.From space, too, we can look down on the Earth and study the atmosphere, its weather, and the effects of air pollution.And because there is no strong gravity to break free from, our future homes away from Earth will be convenient starting points for travel to distant planets.But, while going into space might solve some problems, outer space can also be a dangerous place. For example, in outer space, we have to protect ourselves from the dangers of ultraviolet light and cosmic rays. Ultraviolet light from the sun can give us bad sunburns right here on Earth. Yet, Earth’s atmosphere screens out most of that harmful radiation. Cosmic rays are tiny high energy particles from outer space. Again, the Earth shields us from most of them.At Home in Space?But in space, without special protection, we would be exposed to much stronger radiation from ultraviolet light and cosmic rays. Also, in the zero gravity of outer space, our bones will lose calcium and become weaker. This will be more of a problem the longer people stay out in space. Doctors are looking for a way to keep our bones from losing calcium in outer space. And a small spaceship just might “drive you batty” after a while. But even on a short trip in outer space, you might not feelas well as you’d like to. Space travel could make you seasick!Yet, these risks won’t keep people from going into space. Eventually, an Earth like environment will be built in space. And they will be populated by people with many different interests: medicine, construction, farming, teaching, mining, and so on.The next hundred years will be filled with other worldly adventures, exciting scientific discoveries, and danger, as humans leave Earth—perhaps forever.Aging in SpaceSuppose a space traveler is moving at a velocity of 186,200 miles per second.For every hour that passes for him, 30 hours pass on Earth. If he travels for a year in this fashion (having accelerated instantaneously) and then turns around and comes back at this speed (having turned around instantaneously), he will find that while he has seemed to himself to have traveled two years, the men on Earth would claim he had been absent for 30 years.Suppose the space traveler had left at the age of 30, leaving behind a twin brother also aged 30. When he returned he would be 32, but his stay at home twinbrother would be 60. That is why the “clock paradox”, is sometimes called the “twin paradox”.Of course it takes quite a long while to accelerate to a high speed, and a long while to make a turn and head back again, so conditions aren’t quite as clear cut as just described.1.The giant, spherical spaceship mentioned in the passage is.[A]the outer space[B]a man made spaceship[C]the planet Earth[D]the Star Wars mothe ship2.Some persons have traveled into outer space after conquering within the past 25years.[A]the universe[B]Earth’s gravity[C]the earth[D]outer space3.We have explored or sent robot spaceships to the following space except.[A]the moon[B]Venus[C]Jupiter[D]Mars4.Why is the conquest of space more than a great adventure?[A]Because it is full of challenges for human beings.[B]Because it may be necessary for human beings to survive.[C]Because it is the greatest adventure in human history.[D]Because it is more exciting than any other adventures.5.The moon and the asteroids are alike with respect to their .[A]size and moving ways[B]comfortable living conditions[C]rich and valuable metals[D]solar energy6.Why can’t ultraviolet light scorch our skin on Earth as seriously as it does in space places?[A]Because the Earth’s atmosphere can make ultraviolet light less harmful.[B]Because ultraviolet can’t reach the Earth at all.[C]Because the Earth is far away from those planets radiating ultraviolet light.[D]Because other space places is near from those planets radiating ultravioletlight.7.In spite of many risks, scientists will finally build in space suitable for humans to live.[A]an environment without ultraviolet light[B]a lot of homes[C]an Earth like environment[D]an environment with atmosphere8.The reason some metal alloys can’t be made on Earth is that the heavier metals together with the lighter ones.9.In space, there is no atmosphere to filter out the sun’s energy. There is plentyof solar energy to be turned into, for creating comfortable living conditions.10.According to the author, will be caused to a man in gravity free space.Part III Listening Comprehension(35 minutes)Section ADirections: In this section, you will hear 8 short conversations and 2 long conversations.

Grammar and Vocabulary (每题1 分,共20 分)Section ADirections: After reading the passage below, fill in the blanks to make the passage coherent and grammatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, used one word that best fits each blank.An implant that can cool nerves to block pain signals has been unveiled by researchers who say the device could offer an alternative to drugssuch as opioids (类鸦片活性肽).The team behind the device say it could bring benefits for management of acute pain such as (21)_______ experienced after amputations (截肢)or nerve grafts."We are optimistic that this represents a very promising starting point for an engineering approach (22)_______ treating pain,” said Prof John Rogers of Northwestern University in the US, a co-author of the research. But he cautioned that it might be some time (23) _______ they were available to patients. "As with any implantable device, the regulatory process can be slow, typically (24) _______ (involve) much more extensive animal model studies over a period of years," he said.Writing in the journal Science, the team report that the device to block pain signals, which (25) _______(test) only on rats so far, involves a pump, external control system and an implant made from a soft, rubbery substance. The latter forms a sealed collection of tiny channels which form a twisting path in the part of the implant that sits around the target nerve like a cuff.When liquid coolant and dry nitrogen flow through the implant, the liquid causes a drop in temperature. An electronic sensor in the device allows the temperature at the nerve (26) _______(keep) constant."All body processes are based on metabolic chemical reactions, motions of ions and flows of fluids--all (27) _______slow down as a result ofcooling,” said Rogers. “ The net effect when cooling is applied to a nerve is in blocking of electrical signals."Among their experiments, the team tracked two rats with an injury, recording over a three- week period the minimum force that (28)_______be applied to the hind paw to cause the animal to retract (缩回)it. This data was then compared against three rats who were similarly injured but also had the implant. The results suggest bouts of cooling of the injured nerve from 37℃ to 10℃led to (29) _______(severe) pain, with a sevenfold increase in the force that could be applied to the paw. The team say the implant’s benefits include (30)_______, in contrast to opioids, it is not addictive. As the implant is made with water-soluble and biocompatible materials, it can break down in the body after use. The implant could be inserted as an extension of the patient’s initial surgery.Section BDirections: Complete the following passage by using the -words in the box. Each word can only be used once.

Fitted with GPS collars and tattooed with identification numbers on their gums, the bears are also among the latest (34) _______of a long-term research study being conducted by Rich Beausoleil and Lindsay Welfelt, both biologists and bear and cougar specialists.The siblings were only two weeks old when a forest worker and his dog (35) _______ disturbed their den in February 2020, scaring away their mother. She never returned.The worker contacted the WDFW, an agency (36) _______with PAWS to rehabilitate sick, injured wild animals before releasing them back into their natural habitats."Their eyes and ears weren't open, and their teeth hadn't evenerupted,Jennifer Convy, PAWS senior director of wildlife, said of the cubs, which each weighed less than 2 pounds when they arrived and were the youngest ever to be raised at the center.Though (37) _______at first, the cubs weren't cuddled. Instead, their caregivers wore bear- scented bear suits during feedings once the cubs' eyes had opened. At PAWS, the staff and volunteers take pains to be (38)_______to all the animals in their care."They don't see us, ever. We don't talk to them. We don't name the animals because we don't want our staff or volunteers to get (39)_______,“ Convy said. After more than a year, the bear siblings were released.The wildlife biologists are studying how the bears raised at PAWS fare after their release, compared to their wild-reared brethren. One cub released in 2017 had her first litter of cubs in January."We've been to her den several times." Beausoleil said. "She (40)_______ and had cubs of her own ... This was kind of a turning point for us."After all, the whole point of PAWS' rehabilitation "is to protect and perpetuate (使持续) the species," he said.III. Reading Comprehension (45 分)Section A (每题1分,共15分)Directions: For each blank in the following passage there are four wordsor phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.The Other da Vinci CodeFor centuries, two of the most intriguing questions about Leonardo da Vinci's "Mon a Lisa" were "Who " and "When ”A(n) (41) _______made at Heidelberg University in 2005 pretty much answered both. A note written in a manuscript in the library (42) _______the account of da Vinci's first biographer, Giorgio Vasari: that the sitter was a merchanfs wife, Lisa Gherardini. The note also helped date the masterpiece to between 1503 and 1506.A(n) (43)_______ mystery-"Where "- is still in dispute. But on June 3rd a French engineer, Pascal Cotte, declared that he and a collaborator had (44) _______the landscape in the background of the painting. Arguments had (45)_______ been made for stretches of countryside in the Marche region and between Milan and Genoa. During a presentation in Vinci, near Florence, Mr Cotte maintained that the artist was more plausibly depicting a part of his native Tuscany 一one that keenly interested him at the time. According to this theory, da Vinci represented the area not as it was, but as, in an unrealised scheme, he (46) _______ it to be.Mr Cotte, who was asked by the Louvre (where the "Mona Lisa" hangs) to create a digital image of the painting, is the inventor of themultispectral camera: a device that can detect not only the drawing below the (47) _______of an oil painting, but also, where they exist, intermediate layers of work. It was among these, under what appears to be a pointed rock, that he found a(n) (48) _______sketch showing that da Vinci meant it to represent a castellated tower.The landscape of the "Mona Lisa" also includes a huge overhanging cliff. That is (49)_______ to one that da Vinci included in a sketch of a fortress (堡垒)contested by Pisa and Florence in the war that flared between them in 1503 (around the time he was painting Gherardini). The (50)_______ with the nearby cliff ——and a tower, known as the Caprona tower 一all overlook the river Amo as it snakes from Florence to Pisa. All three also feature in drawings made by da Vinci to illustrate a plan about which, says Mr Cotte, he became “(51) _______”.This involved diverting the Amo to (52) _______Pisa's water supply and give Florence an outlet to the Mediterranean. In the early 1500s, with the two citystates at war, the idea was under active consideration. Mr Cotte argues that a(n) (53) _______ winding through desolate countryside at the right of the "Mona Lisa" is too wide to be a road, as some have speculated, and is(54) _______the driedup bed of the Amo as da Vinci envisaged (设想)it once his plan had been adopted.It never was. But if Mr Cotte's theory is right, it might just explain why Gherardini, a Florentine, exhibits such a contented, if mysterious, (55)_______。

The subjects in his experiment were75college students.They represented all levels of ability in English:beginning,intermediate,and native-speaking students.To begin,the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording,the subjects took a15-question test to see which words they remembered, each question had four choices.The subjects had to circle the word they had heard in the recording. Some of the questions had four choices that sound alike.For example,weather,whether,wither, and wetter are four words that sound alike.Some of the questions had four choices that have the same meaning.Method,way,manner,and system would be four words with the same meaning.Finally the subjects took a language proficiency test.Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike;students with a higher proficiency made more of their mistakes on words that have the same meaning.Henning’s results suggest that beginning students hold the sound of words in their short-term memory,and advanced students hold the meaning of words in their short-term memory.6.Henning made the experiment in order to study.A.how students remember English vocabulary by short-term memoryB.how students learn English vocabularyC.how to develop students’ability in EnglishD.how long information in short-term memory is kept7.Which of the following statements is TRUE according to the passage?rmation in short-term memory is different from that in long-term memory.B.Long-term memory can be achieved only by training.C.It is easier to test short-term memory than long-term memory.D.Henning gave a separate test on vocabulary to his students.8.From Henning’s result we can see that.A.beginners have difficulty distinguishing the pronunciation of wordsB.advanced students remember words by their meaningC.it is difficult to remember words that sound alikeD.it is difficult to remember words that have the same meaning9.The word“subjects”in the passage means.A.memoryB.the theme of listening materialC.a branch of knowledge studiedD.the students experimented onPassage3Questions11to15are based on the following passage:The cowboy is the hero of many movies,.He is,even today,a symbol of courage and adventure. But what was the life of the cowboy really like?The cowboy’s job is clear from the word cowboy.Cowboy were men who took care of cows and other cattle.The cattle were in the West and in Texas.People in the cities of the East wanted beef these cattle.Trains could take the cattle east.But first the cattle had to get to the trains. Part of the cowboy’s job was to take the cattle hundreds of miles to the railroad town.The trips were called cattle drivers.A cattle drive usually took several months.Cowboys rode for sixteen hours a day.Because they rode so much,each cowboy brought along about eight horses.A cowboy changed horses several times each day.The cowboys had to make sure that cattle arrived safely.Before starting on a drive,the cowboys branded the cattle.They burned a mark on the cattle to show who they belonged to.But these marks didn’t stop rustlers,or cattle thieves.Cowboys had to protect the cattle from rustlers.Rustlers made the dangerous trip even more dangerous.Even though their work was very difficult and dangerous,cowboys did not earn much money.They were paid badly.Yet cowboys liked their way of life.They lived in a wild and open country.They lived a life of adventure and freedom.11.A cowboy is a symbol of.A.courage and adventureB.a hard life and big payC.movies in the pastD.cows and other cattle12.The cowboys’job was.A.to be a hero in real lifeB.to be a hero of the movieC.to take care of cattleD.to be a dangerous rustler13.During a cattle driver,cowboys took a group of cows from a wild and open country to.A.the West states and TexasB.the cities of the East StatesC.the people who eat beef in citiesD.the railroad towns hundred miles away14.On their way of cattle drivers,the cowboys protected the cattle by.A.burning a mark on their cowsB.keeping an eye on cattle thievesC.making the trip more dangerousD.looking after eight cows each person15.Cowboys enjoyed themselves because.A.they liked their way of lifeB.they made a lot of moneyC.they had a vary difficult jobD.they were heroes in moviesPassage4Questions16to20are based on the following passage:Successful innovations have driven many older technologies to extinction and have resulted in higher productivity,greater consumption of energy,increased demand of raw materials,accelerated flow of materials through the economy and increased quantities of metals and other substances in use each person.The history of industrial development abounds with examples.In1870,horses and mules were the prime source of power on U.S.farms.One horse or mule was required to support four human beings a ratio that remained almost constant for many decades. At that time,had a national commission been asked to forecast the population for1970,its answer probably would have depended on whether its consultants were of an economic or technological turn of mind.Had they been“economists”,they would probably have projected the1970horses or mule population to be more than50million.Had they been“technologists”,they would have recognized that the power of steam had already been harnessed to industry and to learn and ocean transport. They would have recognized further that it would be the prime source of power on the farm.Itwould have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.16.According to the passage,what supplied most of the power on U.S.farms in1870?A.AnimalsB.HumansC.EnginesD.Water17.Which of the following is NOT mentioned by the author as a consequence of new technological developments?A.Older technologies die away.B.The quality of life is Improved.C.Overall productivity increase.D.More raw materials become necessary.18.It can be inferred from the passage that by1870.A.technology began to be more economicalB.the steam engine had been inventedC.the U.S.horse population was about10millionD.a national commission was about10million19.In the second paragraph,the author suggests that“economists”would.A.plan the economy through yearly forecastsB.fail to consider the influence of technological innovationC.value the economic contribution of farm animalsD.consult the national commission on the economy20.What is the author’s attitude toward changes brought on by technological innovations?A.He is excited about them.B.He accept them as natural.C.He is disturbed by them.D.He questions their usefulness.Questions16to20are based on the following passage:This semester I began to have a series of teacher nightmares,something that had not happened to me for years,not since my first year of teaching when I was in a perpetual state of dread.I would be rushing to get to class on time,trying to gather up notes from a maelstrom of papers on my desk,not certain what subject we were covering today,indeed not even certain what course I was teaching.My heart was pounding.I was late.I would not find my notes.A hundred people were waiting for me in the classroom,their pens poised to take down my every syllable,and I had nothing to say.Them Mr.Winthrop’s big blonde face with those dark eyes would loom at the door of my office,and with that mocking grin,he would say,“Professor,the class is waiting for you,”and I would faint dead onto the floor.Or sometimes in my dream I would make it to the podium(讲台),start to lecture on some aspect of criminal law or causation,only to have Mr.Winthrop raise his hand,and without even waiting to be called upon,presumably ask a question. Presumably because I could not make out his words.I could see his mouth moving underneath his baseball cap,and muffled sounds resounded in my ears,but I could not understand him.All eyes in the classroom were on me,and my students began to laugh,but not Mr.Winthrop.He continued to move his mouth,and I felt as if I was watching TV with the sound off except that my head was all a buzz with the laughter and the shuffling of feet as my students exited in disgust.Again, I ended the nightmare by fainting dead away onto the floor,and then I would wake up,my sheets damp from desperation.It was enough to make a man get out of bed and mix a drink at four in the morning even if he had the eight o’clock class.16.From this passage,it is indicated that.A.the first year of teaching is unforgettable and frightening for me foreverB.nightmares have happened to me more often than not since my first year of teachingC.in my first year of teaching,I was always full of fearsD.as a

考研数学三线性代数(矩阵的特征值和特征向量)模拟试卷2(题后含

考研数学三线性代数(矩阵的特征值和特征向量)模拟试卷2(题后含答案及解析)题型有:1. 选择题 2. 填空题 3. 解答题选择题下列每题给出的四个选项中,只有一个选项符合题目要求。

1.已知P-1AP=,α1是矩阵A属于特征值λ=1的特征向量,α2与α3是矩阵A属于特征值λ=5的特征向量,那么矩阵P不能是( ) A.[α1,-α2,α3].B.[α1,α2+α3,α2-2α3].C.[α1,α3,α2].D.[α1+α2,α1-α2,α3].正确答案:D解析:若P-1AP=A=,P=(α1,α2,α3),则有AP=PA.即(Aα1,Aα2,Aα3)=(a1α1,a2α2,a3α3)可见αi是矩阵A属于特征值ai(i=1,2,3)的特征向量,又因矩阵P可逆,因此α1,α2,α3线性无关.若α是属于特征值A的特征向量,则-α仍是属于特征值λ的特征向量,故选项A正确.若α,β是属于特征值λ的特征向量,则2α+3β,…仍是属于特征值λ的特征向量.本题中,α2,α3是属于λ=5的线性无关的特征向量,故α2+α3,α2-2α3仍是λ=5的特征向量,并且α2+α3,α2-2α3线性无关,故选项B正确.对于选项C,因为α2,α3均是λ=5的特征向量,所以α2与α3谁在前谁在后均正确.故选项C正确.由于α1,α2是不同特征值的特征向量,因此α1+α,α1-α2不再是矩阵A的特征向量,故选项D错误.所以应选D.知识模块:矩阵的特征值和特征向量2.设A为n阶可逆矩阵,λ是A的一个特征值,则A的伴随矩阵A*的特征值之一是( )A.λ-1|A|B.λ-1|A|C.λ|A|D.λ|An|正确答案:B解析:设向量x(x≠0)是与λ对应的特征向量,则由特征值与特征向量的定义有Ax=λx.上式两边左乘A*,并考虑到A*A=|A|E,得A*Ax=A*(λx),即|A|x=λA*x,从而可见A*有特征值所以应选B.知识模块:矩阵的特征值和特征向量3.已知A是三阶矩阵,r(A)=1,则λ=0( )A.必是A的二重特征值.B.至少是A的二重特征值.C.至多是A的二重特征值.D.一重、二重、三重特征值都有可能.正确答案:B解析:A的对应λ的线性无关特征向量的个数≤特征值的重数.r(A3×3)=1,即r(0E-A)=1,(0E-A)x=0必有两个线性无关特征向量.故λ=0的重数≥2.至少是二重特征值,也可能是三重.例如A=,r(A)=1,但λ=0是三重特征值.所以应选B.知识模块:矩阵的特征值和特征向量4.设λ=2是非奇异矩阵A的一个特征值,则矩阵有一特征值等于( ) A.B.C.D.正确答案:B解析:因为λ为A的非零特征值,所以λ2为A2的特征值,为(A2)-1的特征值.因此的特征值为.所以应选B.知识模块:矩阵的特征值和特征向量5.三阶矩阵A的特征值全为零,则必有( )A.秩r(A)=0B.秩r(A)=1C.秩r(A)=2D.条件不足,不能确定正确答案:D解析:考查下列矩阵它们的特征值全是零,而秩分别为0,1,2.所以仅由特征值全是零是不能确定矩阵的秩的.所以应选D.知识模块:矩阵的特征值和特征向量6.设n阶矩阵A与B相似,E为n阶单位矩阵,则( )A.λE-A=λE-BB.A与B有相同的特征值和特征向量.C.A和B都相似于一个对角矩阵.D.对任意常数t,tE-A与tE-B相似.正确答案:D解析:因为由A与B相似不能推得A=B,所以选项A不正确.相似矩阵具有相同的特征多项式,从而有相同的特征值,但不一定具有相同的特征向量,故选项B也不正确.对于选项C,因为根据题设不能推知A,B是否相似于对角阵,故选项C也不正确.综上可知选项D正确.事实上,因A与B相似,故存在可逆矩阵P,使P-1AP=B 于是P-1(tE-A)P=tE-P-1AP=tE- B.可见对任意常数t,矩阵tE-A与tE-B相似.所以应选D.知识模块:矩阵的特征值和特征向量7.n阶矩阵A和B具有相同的特征值是A和B相似的( )A.充分必要条件.B.必要而非充分条件.C.充分而非必要条件.D.既非充分也非必要条件.正确答案:B解析:由A-B,即存在可逆矩阵P,使P-1AP=B,故|λE-B|=|λE-P-1AP|=|P-1(λE-A)P|=|P-1||λE-A||P|=|λE-A|即A 与B有相同的特征值.但当A,B有相同特征值时,A与B不一定相似,例如虽然A,B有相同的特征值λ1=λ2=0,但由于r(A)≠r(B),A,B不可能相似.所以,相似的必要条件是A,B有相同的特征值.所以应选B.知识模块:矩阵的特征值和特征向量填空题8.设A是3阶实对称矩阵,特征值分别为0,1,2,如果特征值0和1对应的特征向量分别为α1=(1,2,1)T,α2=(1,-1,1)T,则特征值2对应的特征向量是______正确答案:t(-1,0,1)T,t≠0解析:设所求的特征向量为α=(x1,x2,x3),因为实对称矩阵不同的特征值对应的特征向量是正交的,因此有所以可知x1=-t,x2=0,x3=t.所以对应于特征值2的特征向量是t(-1,0,1)T,t≠0.知识模块:矩阵的特征值和特征向量9.设A为2阶矩阵,α1,α2为线性无关的2维列向量,Aα1=0,Aα2=2α1+α2,则A的非零特征值为________正确答案:1解析:根据题设条件,得A(α1,α2)=(Aα1,Aα2)=(0,2α1+α2)=(α1,α2)记P=(α1,α2),因α1,α2线性无关,故P=(α1,α2)是可逆矩阵.因此,则A与B相似,从而有相同的特征值.因为所以λ=0,λ=1.故A的非零特征值为1.知识模块:矩阵的特征值和特征向量10.设n阶可逆矩阵A的一个特征值是-3,则矩阵必有一个特征值为_________正确答案:解析:根据矩阵特征值的特点,A有特征值-3,所以有特征值知识模块:矩阵的特征值和特征向量11.若3维列向量α,β满足αTβ=2,其中αT为α的转置,则矩阵βαT的非零特征值为_______正确答案:2解析:因为αTβ=2,所以βαTβ=β(αTβ)=2×β,故βαT的非零特征值为2.知识模块:矩阵的特征值和特征向量12.设α=(1,-1,a)T是A=的伴随矩阵A*的特征向量,其中r(A*)=3,则a=__________正确答案:-1解析:α是A*的特征向量,设对应于α的特征值为λ0,则有A*α=λ0α,该等式两端同时左乘A,即得AA*α=|A|α=λ0Aα,即展开成方程组的形式为因为r(A*)=3,|A*|≠0,因此λ0≠0,根据方程组中的前两个等式,解得a=-1.知识模块:矩阵的特征值和特征向量13.已知矩阵A=的特征值的和为3,特征值的乘积是-24,则b=________正确答案:-3解析:已知一个矩阵的所有特征值的和等于该矩阵对角线元素的和,因此a+3+(-1)=∑λt=3,所以a=1.又因为矩阵所有特征值的乘积等于矩阵对应行列式的值,因此有所以b=-3.知识模块:矩阵的特征值和特征向量14.设A=有二重特征根,则a=________正确答案:解析:=(λ-2)(λ2-2λ-2(a-2))=0.如果λ=2是二重根,则有λ=2的时候,λ2-2λ-2(a-2)的值为0,可得a的值为2.如果λ2-2λ-2(a-2)=0是完全平方,则有(λ-1)2=0,满足λ=1是一个二重根,此时-2(a-2)=1,即a= 知识模块:矩阵的特征值和特征向量解答题解答应写出文字说明、证明过程或演算步骤。

No reliable statistics show how many parents or schools use it, but the Positive Discipline Association, a non-profit that ran 18 training workshops in 2005, found itself running 51 in 2010. Doubters fear that positive really means permissive. Not so, says Maria Vannucci of the Adler School of Professional Psychology in Chicago. The goal is to connect with a child, rather than simply barking “Shut up!”or “Go to your room!”For example, a child who is getting underfoot in the kitchen may need to feel involved and be given something to do, such as rolling pastry or folding napkins. One who has given up on his homework may need to have the task broken down. A toddler who hits another may not know why he is angry; he may be removed or told: “Use your gentle hands. “Bribes are out: positive disciplinarians fear they may prevent a child from developing pride in a job well done.6.According to Paragraph 1, which one of the following is true?A.Positive discipline is absolutely superior to “naughty step”.B.Parents used to choose more violent ways to teach their children.C.Supernanny advises parents to use “naughty step” and “positive discipline”.D.Some people suggest “naughty step”is both physically and mentally damaging.正确答案:B解析:选项[A]是无中生有。
