Test Yourself1Passage OneLaura walked towards the man. "It is terribly cold," she said."Colder than ever," the man said. "Now tell me what the hell you want." He stared at Laura for a few seconds, and then grinned, "Maybe you'd like to come inside and warm up. "No. No, I don't want to come in." She took a deep breath. "I just wanted to know if you're interested in selling your dog." "That worthless mutt?" The man pointed to a dog in the yard and laughed for a few seconds, then suddenly stopped. "I was just joking about the worthless part. He's a pretty good dog. Yeah. I might be interested." "Well, he's the kind of dog I'm looking for, and it doesn't look to me like you're too fond of him. I mean he' s tied up outside. I don't see any food or water." "You just wait a minute. I take good care of that dog. The guy I got him from said he was a trained guard dog. Trouble is the stupid thing doesn't even bark when strangers come around. But then I guess that wouldn't matter to you. You' re probably just looking for a pet, huh?" "Yeah, well here's your chance to get rid of him.I'll give you twenty dollars." He snorted(哼着鼻子说) . "You expect me to sell a purebred guard dog for twenty dollars? Fifty dollars. That' s my price. You bring me fifty dollars, honey, and you got yourself a dog." The man smiled. "Sure you don't want to come in?" Laura shook her head. "I'll be back with the money." Breakfast forgotten, she searched for and found a cash machine four blocks away. I can't afford this, she thought as she punched the numbers into the machine. The dog will need a vet(兽医) and where am I going to get the money for that? Her fears faded(消退) as she pictured the dog, curled up, not outside on the cold, hard ground, but in frontof a glowing fireplace.Blue ceramic bowls filled with food and water sat in the corner of the kitchen, and she saw him, head held high, matching her stride on their daily walk. With the money in her purse she hurried back to the man's house.26. Why did Laura walk up to the man?A. To ask him where she could buy a pet.B. To see if she could buy his dog.C.

She's got the money in her purse to pay for the pet she desiredTest Yourself1Passage TwoAlthough Thomas Jefferson did not begin the effort of designing the University of Virginia until late in his life, the education of the common man had occupied his thoughts for decades. He believed ignorance (无知) to be the enemy of freedom, and he wanted to correct what he considered to be the weaknesses of educational institutions (机构) modeled on European settings. He imagined that an "academical village" around a tree-lined lawn would provide an ideal setting in which to pursue higher education. The center of such a village would be a Temple of Knowledge that would house the university library.When Virginia decided to set up a state university in 1818, the retired U.S. President finally was able to devote his talent, time, and energy to creating this new kind of educational institution. By the time he was finished with his design, Jefferson had invented an entirely new American setting for higher education: the college campus.In 1812, Jefferson chose to begin building his "academical village," the University of Virginia, in Charlottesville, VA, far away from the city center. He intended this spot to promote learning because it was natural and unspoiled, and far from anything that could distract or harm the students. The University consists of two rows of houses, five on each side, leading to a main building. This main building, the Rotunda, became the most important part of the University, because it contained the library. By focusing his entire institution on the library, instead of around the church, Jefferson revolutionized American university architecture.Jefferson's aim was to create a new institutional form for his ideal educational system, a system he thought should give every citizen the information he needs for carrying out his daily business. This new approach to citizenship and education demanded a new type of university, one where students and professors could coexist and share ideas. He attempted to create this environment by combining the professors' houses and students' classrooms, and linking all the buildings with covered walkways so intellectual exchanges between departments could go on smoothly. Jefferson had also recognized the importance of the students' whole life, and given much thought and planning to the students' dining, living, and exercise facilities (设施).31. Jefferson devoted much of his thought to the education of the common man because he believed ________.A. everyone who loved freedom hated ignoranceB. a country could not be strong without educationC. an uneducated man could not gain full freedomD. European educational institutions did not suit America32. According to Jefferson, the center of a university should be _______.A. the churchB. the libraryC. the lawnD. the classrooms33. Jefferson chose to locate the University of Virginia far away from the city center because ________.A. land in the city center could not be foundB. there was a tree-lined lawn thereC. this was a European traditionD. there was no distraction for the students34. In Jefferson's view, an ideal educational system should ________.A. be one under which every citizen enjoys equal opportunityB. give everyone the information he needs for conducting his businessC. ensure that everyone has a chance to enter an institution of higher learningD. provide students with a natural and unspoiled setting for learning35. What was made easy by the revolutionized American campus?A. Students' learning.B. Intellectual exchange.C. Professors' teaching.D. Both students' and professors' life.Test Yourself1Passage ThreeThe good news we get from TV and radio makes us feel more kindly toward other people, but bad news — especially news of cruelty and violence — stirs up suspicion and a sense of competition toward others.These are the findings of 10 years of experiments by research psychologists (心理学家) at Columbia University, who conclude that broadcasters encourage hostile (敌对的) behavior by stressing bad news."We found that the news people are exposed to either encourages them to concentrate on the differences between themselves and others, or on the common problems that make them feel,'We're all in this together,' " explained Dr. Harvey Hornstein."'News about one human being helping another … brings out feelings of trust and cooperation. But news about one person actually doing harm to another changes our estimate of other people for the worse."”In an early experiment in 1968, Dr. Hornstein and his associates, who had been dropping wallets (钱包) for two years to test the honesty of people, discovered that on June 4, 1968, not one wallet was returned."That was the night Robert F. Kennedy was shot," he recalled. "Strangers suddenly seemed dangerous, and nobody wanted to return a lost wallet to a stranger.""But good news on the other hand, lifts us up," he stressed, citing the date of July 4, 1976, America’s Bicentennial (两百年的) celebration. "On that day, we all felt safe and good. Being American was the thing. We all felt as if we all belonged together."Recent tests support these conclusions. In one experiment, 60 subjects were exposed to good news, bad news or music. Then they were told to play a game with a non-existent person supposedly in another room. It was a game of choice that emphasized cooperation or competition.After hearing good news, the overwhelming majority, 91 percent, played cooperatively. But after hearing bad news, competitive responses were over three times as high — up to 28 percent, from 9 percent."If we watch television and see a lot of blood," said Dr. Hornstein, "we’re probably assuming that the world is a dirtier place than we assumed before we saw that TV violence. And we’ll deal with the next individual we come up on as if he is part of that grim (冷酷的) picture of humanity. After the good news, it’s the reverse."36. According to the findings of researchers at Columbia University, when people hear good news, they feel _______.A. happierB. more kindly toward othersC. safer than they really areD. more competitive37. Dr. Harvey Hornstein found that when people hear news about one person actually doing harm to another, they tend to _______.A. regard other people as worse than they really areB. treat total strangers as suspects of cruel crimesC. become hostile towards neighbors and friendsD. think about the common problems facing mankind38. What did Dr. Harvey Hornstein and his associates discover on the night of June 4, 1968?A. Robert F. Kennedy was shot.B. Their wallets were lost.C. People in America suddenly became dishonest.D. Nobody returned the wallets they dropped.39. We can infer from the passage that on July 4, 1976, most probably _______.A. people drank and sang and dancedB. lost wallets were returned to their ownersC. everybody wanted to be AmericanD. even criminals were friendly to others40. We can conclude from the passage that _______.A. violence on TV leads to more violence on the streetsB. broadcasters should emphasize good news rather than bad newsC. the world is a dirtier place than we assume it to beD. people are more competitive when they are faced with challengesKaleil Isaza Tuzman moved to the United States from Columbia when he was 15. Within a few years he was pushing to get ahead, hawking (叫卖) baseball caps to pay the bills his Harvard scholarship didn't cover.After graduating, he landed on Wall Street, but every night he dreamed of working for himself. During the booming (繁荣的) 1990s, he gave it a try when he and a partner started govWorks - a software company that helped city government go online.They raised $60 million and expanded like crazy. Then dotcoms started turning into dotbombs - govWorks broke up too. Says Isaza Tuzman, "Entrepreneurs (创业人) have to be ready for both success and failure. In Columbia if you fail, you become a pariah and no one will do business with you. The wonderful thing about this country is you can get up again."From national parks to moon landings, America has given the world some amazing ideas. But the American Dream is still the biggest - the idea that with hard work and a bit of luck you can be whoever you want to be. Historian James Truslow Adams once wrote that Americans believe "life should be better and richer and fuller for everyone, with opportunity for each according to ability or achievement."These days there's pressure on the dream idea. A 1978 study of boys born and raised after World War II found an astonishing 23% of the poorest had reached the top of the income heap by 1973. Now, in a typical generation, only 10% work their way from bottom to top.But every day, some still do make it. After govWorks went bankrupt, Isaza Tuzman built on what he had learned. His new company, Recognition Group, restructures (重组) firms and finds them venture capital – nearly $150 million so far. Last year, "Hispanic Business" magazine named him to its 100 Most Influential list. Not bad for a dreamer, in a country built on dreams.41. What did Kaleil Isaza Tuzman dream of after graduating from college?A. Working in the Wall Street stock market.B. Starting a business of his own.C. Climbing to the top of society.D. Entering the IT industry.42. The word "pariah" in " if you fail, you become a pariah" (Line 3,Para. 3) most likely means "________."A. a person who has no futureB. a person to be pitiedC. a person to be condemnedD. a person to be avoided43. What does the author mean by the American Dream?A. Everyone can reach the top of the social ladder.B. People will have a better, richer, and fuller life than their parents.C. A lucky poor boy can move to the top if he works hard.D. Everyone enjoys equal opportunity and share in the wealth.44. Which of the following statements is true of the American Dream these days?A. It is becoming more and more difficult for one to work their way from the bottom to the top.B. More and more people are feeling the pressure to work harder in order to realize their dreams.C. It is becoming more and more unpopular because few people today can move up the social ladder.D. If one works hard enough, he will eventually make his dreams come true.45. To Kaleil Isaza Tuzman, the wonderful thing about America is that ________.A. there is equal opportunity for everyoneB. everyone can get rich if they work hardC. you can get capital if you want to start a businessD. you can start all over again after failureTest Yourself1Vocabulary and Structure46.

血迹检验_侦探推理常识（The blood test _ detective of commonsense）Blood test is one of the most common forensic physical evidence tests. It can often be solved is not blood, human bloodAnimal blood, what kind of blood group, blood or blood of women, and bleeding site, bleeding time and bleeding volume and so onIt can provide important clues and basis for investigation and trial.First, the naked eye examinationNaked eye examination is to find blood, observe its color, shape and location, in order to prepare for the next step of the testAnd to lay a foundation, and to determine the nature of the case, analysis and judgment of the case to help.In violent cases such as homicide and injury, blood may be left on the scene, on the victim and on the criminal.In general, the blood is visible, not difficult to view, but sometimes need to carefully check to find out.The color of fresh blood is bright red, and it gradually changes to dark red and dark due to the change of hemoglobin after in vitroBrown, old or warm blood, gray brown, corrupt blood is palegreen or green. Blood if attached toDark objects, the color is not obvious. The color of soy sauce, paint, juice, pigment, rust and so on, and its color can also be usedBlood color is similar, should pay attention to the difference.Because of the different conditions of blood formation, the shape of blood is different:1. drops of bloodstainThe blood drops vertically on the ground or objects, forming a round drop of blood. Its shape is also due to the height and movement of the dropThere are differences between directions of motion. If the blood falls within 0.1 meters, the edge of the blood is rounded;At the height of about 0.5 meters, the edges of the dots can be distinctly serrated, and the dots will fall when the quotient is more than 1 metersNot only the visible jagged edge, and often funny dots around the point or line of small drops of blood. If the blood is in the injured lineEntering or moving from an object (such as a vehicle), the blood is oval, and the end is like a star like protuberance with a projecting tipPoint to the direction of motion.2. splash bloodstainThe rupture of an artery, the pressure produced by the contraction of the heart, and the retraction of the arterial wallBut, like the blood splash formed in the vicinity of the exclamation point on the object, its tip pointing to the direction of splash. If using blunt repeatAttack and injury bleeding, also can form splash blood, but its size and shape is different, scattered distribution.3. column blood stainsBlood flows out of the wound, along the body or other objects from high to low to the lower, forming a thin, thick, light and thickBloody stripes.4. wipe bloodstainAn object or wound that has blood contact with other objects, and moves and friction, can form a larger area,Uneven wiping blood stains.5. contact bloodstainWith the objects or cut blood contact with other objects, without moving or friction, can leave traces of blood,Such as blood fingerprints, blood footprints. Contact bloodstain can reflect the appearance features of blood stained objects or wounds.6. pool of bloodA large amount of blood flows out, and it becomes blood pools.A pool of blood is often the first place to be injured or killedOne scene.In addition, pay attention to the location and location of the blood left behind, help to analyze the injured or injured before deathMovement and position and posture at that time.Two. Preparation testThe trial is a preliminary and exploratory blood test to determine whether there is a possibility of blood contamination. PreThe method is simple, sensitive and specific. Positive results can only prove the presence of bloodstains on the specimenEnergy, not sure, is blood. Of course, the negative results of this test can exclude the possibility of bloodstainYou don't have to go on to the next test.A lot of blood test preparation methods, common benzidine test, phenolphthalein test, aminopyrine test, RumiPromise luminescence test, ultraviolet inspection, etc..1. benzidine testThe sensitivity of this test is very high, and it can be carried out only with trace material. A small amount of material was placed in the white filter during the testOn paper or white board, and then drip into glacial acetic acid, benzidine anhydrous alcohol saturated solution and 3% hydrogen peroxide oneDrop. If there is blood on the material, there will be a turquoise blue reaction, but this reaction may also occur in other substances,It's not unique to blood. Therefore, if the test is positive, it can only indicate that there may be blood on the material.2. UV inspectionThe blood stain is brown and reactive under ultraviolet light, so ultraviolet examination can identify whether there is bloodor notPossibility of trace.3. phenolphthalein testLike benzidine test, the sensitivity of this test is also very high. In the test, a small amount of material was placed on the white magnetic plate,Samples soaked with distilled water, adding Phenolphthalin reagent and 3% hydrogen peroxide one drop, such as blood, immediately appear red.4. luminol chemiluminescence testWith luminol, 0.1 g, 0.5 g of sodium peroxide with distilled water, 100 ml of reagent. The reagents should be tested during the testThe glass is sprayed into the glass, and the material is sprayed in the dark room or at night. If it's blood, it will show a clear greenWhite luminescence phenomenon. This reaction is not specific either.[supplement] about LuminoLumino (luminol), also known as luminous ammonia. You can identify by cleaning, long ago bloodstains. It is a yellowcrystal or beige powder at room temperature. It is a strong acid which has certain stimulating effect on eyes, skin and respiratory tract.In the test of bloodstain, Lumino and heme (a protein responsible for the transport of oxygen in the reaction of hemoglobin) showed blue-green fluorescence, sensitivity can reach 1/1000000. Note that, first of all, Lumino needs to use in the dark environment, otherwise it is difficult to identify the fluorescent light; Lumino limited time, to seize the time to take pictures; finally, it and other oxidising substances also react when used should note distinction.Three. Confirmatory testAfter preparation test, if the specimen is positive, the possibility of bloodstain exists, which needs further confirmationProof test to see if it's blood. Contrary to the preparative test, the confirmatory test is specific, but the sensitivity is lowIt is difficult to produce positive reaction if the sample material is poor, such as sunshine, rain, mixed with impurities or corrupt blood. thusPositive results of confirmatory tests can be positive for blood, but negative results can not completely exclude the possibility of the presence of blood.There are many methods for confirmatory test, such as the crystallization test of scarlet, the crystallization test of red blood violet and the spectrum examination.1. crystal test of scarletThe hemoglobin in blood is decomposed into ferric and denatured proteins in alkaline solution, and then reduced to the reducing agentThe heme is reduced to heme and bound to denatured globin or other nitrogen compounds to form a red blood knotCrystal. According to this principle to test, the use of the original crystal appearance can determine whether blood. Test time,Reagents were first mixed with 10% NaOH aqueous solution 3 ml, pyridine 3 ml and 30% dextrose aqueous solution l0 ml.Take a small amount of samples, placed in a slide, and the reagent 1 - 2 drop, cover glass, heating to shoot at small bubbles, coldMirror examination. If it is blood, it can appear cherry red needle, chrysanthemum shaped or star shaped blood crystal.2. hemin crystallization testThe hemoglobin in the blood destroys the globulin by acid, and produces the red blood serum, and the action of glacial aceticacid and sodium chloride,The formation of free chloride, the interaction between hemin and free chlorine produces a brown rhombic hemin crystal. According to the principle of reaching one,In the test, 10% Sodium Chloride Solution 2 ml, 10 ml glacial acetic acid and 5 ml of anhydrous alcohol were used to prepare reagentsA little, placed in a slide, tests the agent 1 - 2 drop, cover glass, slightly heated, cooled after microscopic examination. Blood stains,Brown diamond crystals are visible.3. spectral inspectionWhen sunlight passes through colored liquids, some wavelengths of light are absorbed,Absorption of stripe shadow on the spectrumLine。
