中科大综合英语听力教程Unit2
中科大综合英语听力教程Unit2U n i t T w o Life and SuccessPart I Schooling and Growing-upTask 3Directions: Listen to the following passage about the influence of television on children. The passage will be read only once. After listening, choose the best answer from the four suggested choices marked A, B, C, andD to each of the questions you hear.Children in the United States are exposed to many influences other than that of their families. Television is the most significant of these influences, because the habit of watching television usually begins before children start attending school. And, by the time that the average child finishes high school, he or she will have spent 18,000 hours in front of a television set as opposed to 12,000 hours in a classroom.Parents are concerned about these figures. They are also concerned about the lack of quality in television programs for children. The degree of violence in many of these shows also worries them. Even if it is unreal--a cartoon cat beating up a cartoon mouse with a baseball bat--this violence may have a negative effect on the young minds exposed to it. Studies indicate that, when children are exposed to violence, they may become aggressive or insecure.Parents are also concerned about the commercials that their children see on television. Manyparents would like to see fewer commercials during programs for children. And some parents feel that these shows should not have any commercials at all because young minds arenot mature enough to deal with the claims made by advertisers.Educational television has no commercials and has programs for children that many parents approve of. The most famous of these is "Sesame Street," which tries to give preschool children a head start in learning the alphabet and numbers. It also tries to teach children useful things about the world in which they live.Even though most parents and educators give "Sesame Street" and shows like it high marks for quality, some critics argue that all television, whether educational or not, is harmful to children. These critics feel that the habit of watching hours of television every day turns children into bored and passive consumers of their world rather than encouraging them to become active explorers of it.Questions:1.What is this passage mainly about?2.At what time does the habit of watching television usually start?3.How many hours have American children spent watching television when they finish high school?4.Why do some parents feel television shows shouldn't include any commercials?5.What kind of program is "Sesame Street"?6.Why do some critics think that all television is harmful to children?1. A. Television programs in the United States are of low quality.B. Watching too much television is undesirable for children.C. The degree of violence in television programs is too high.D. There shouldn't be any commercials on television.2. A. Before children finish high school.B. Before children start high school.C. Before children start attending kindergarten.D. Before children start attending school.3. A. 12,000 B. 20,000 C. 18,000 D. 80,0004. A. Because children are not mature enough to deal with the claims made by advertisers.B. Because children will become aggressive and insecure.C. Because children will be distracted from their studies.D. Because children will be more willing to watch them.5. A. Violent B. Commercial C. Military D. Educational6. A. Because children will become bored and passive.B. Because children will be unwilling to go to school.C. Because children will use violence at school.D. Because children will become lazy and useless.In bringing up children, every parent watches eagerly the child’s acquisition of each new skill—the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself.Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs ofthe parents and the values of the community as much as the child’s own happiness.As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also parents should realize that “example is better than precept”. If they are not sincere and do not practice what they teach, their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a big difference between their parents’ principles and their morals can be a dangerous disappointment.Questions:1.What does every parent eagerly want his/her child to acquire, according to the speaker?2.What consequences might occur if parents push the child beyond his/her natural learning rate?3.What should parents do in the learning process of children?4.What does this passage say about parental restrictions on children?5.What is very important in parental teaching, according to the speaker?6.What should parents do as to the development of moral standards in the growing child?Task 3Directions: You are going to listen to a passage about parental teaching. The passage will be read only once. After listening, you are expected to choose the best answer from the four suggested choices marked A, B, C,and D to each of the questions you hear.1. A. New skills.B.Independence.C.Moral values.D.Learning aptitude.2. A. The child might lose natural enthusiasm for life.B.The child might have dangerous feelings of failure and states of worry.C.The child might have a desire to find out new things for himself.D.The child might feel unhappy about his/her parents.3. A. T hey should encourage them to read before they know the meaning of the words they read.B.They should not expect too much of their children.C.They should create as many learning opportunities as possible.D.They should achieve a balance between pushing them too hard and leaving them on their own.4. A. They are for the benefit of the children alone.B.They reflect the morals of parents.C.They represent the needs of the parents and the values of the community.D.They greatly affect the child’s own happiness.5.A. Instruction.B.Consistency.C.Strictness.D.Patience.6. A. They should observe the rules themselves.B.They should be aware of the marked difference between adults and children.C.They should forbid things which have no foundation inmorality.D.They should ensure the security of their children.Part III Competition and ChallengeTask 3Directions: You are going to listen to a passage about musical prodigies. The passage will be read only once. After listening, you are expected to choose the best answer from the four suggested choices marked A, B, C,and D. to each of the questions you hear.Violin prodigies, I learned, have come in distinct numbers from distinct regions. Most of the great performers in the late 19th and early 20th centuries were born and brought up in Russia and Eastern Europe. I asked Issac Stern, one of the world’s greatest violinists the reason for this phenomenon. “It is very cle ar,” he told me. They were all Jews and Jews at the time were severely oppressed and ill-treated in that part of the world. They were not allowed into the professional fields, but they were allowed to achieve excellence on a concert stage.” As a result, ev ery Jewish parent’s dream was to have a child in the music school because it was a passport to the West.Another element in the emergence of prodigies, I found is a society that values excellence in a certain field to nurture talent. Nowadays, the most nurturing societies seem to be in the Far East. In Japan, a most competitive society, children are ready to test their limits every day in many fields, including music. When Western music came to Japan after World War II, that music not only became part of their daily lives, but it became a discipline as well. The Koreans and Chinese as we know, are just as highly motivated as the Japanese.That’s a good thing, because even prodigies must workhard. Next to hard work, biological inheritance plays an important role in the making of a prodigy.Questions:1.Where were most of the great musicians born and brought up in the late 19th and the early 20th centuries?2.Who was Issac Stern?3.Why did Jewish parents long for their children to attend music school?4.What contributes to the emergence of musical prodigies according to the passage?5.What else plays an important role in the making of a prodigy, according to the passage?6.What is this passage mainly about?1. A. In America.B.In Russia and Eastern Europe.C.In Japan.D.In the Far East.2. A. A musical prodigy.B.A great pianist.C.A great violinist.D.A music instructor.3. A. Because it would allow them access to a better life in the West.B.Because Jewish children are born with excellent musical talent.C.Because they wanted their children to enter into the professional field.D.Because it would enable the family to get better treatment in their own country.4. A. Musical Environments.B.Extensive knowledge of music.C.A prejudice-free society.D.Very early training.5.A. The learning of Western music.B.Biological inheritance.C.Variety in academic studiesD.All-round development.6. A. Jewish contribution to music.B.Training of musicians in the world.C.Music and society.D.The making of prodigies.。

2022年考研考博-考博英语-中国科学技术大学考试全真模拟全知识点汇编押题第五期（含答案）一.综合题(共15题)1.单选题To say that the child learns by imitation and that the way to teach is to set a good example oversimplifies. No child imitates every action he sees. Sometimes, the example the parent wants him to follow is ignored while he takes over contrary patterns from some other example. Therefore we must turn to a more subtle theory than “Monkey see, monkey do.”Look at it from the child’s point of view. Here he is in a new situation, lacking a ready response. He is seeking a response which will gain certain ends. If he lacks a ready response for the situation, and cannot reason out what to do, he observes a model who seems able to get the right result. The child looks for an authority or expert who can show what to do. There is a second element at work in this situation. The child may be able to attain his immediate goal only to find that his method brings criticism from people who observe him. When shouting across the house achieves his immediate end of delivering a message, he is told emphatically that such a racket is unpleasant, that he should walk into the next room and say his say quietly. Thus, the desire to solve any objective situation is overlaid with the desire to solve it properly. One of the early things the child learns is that he gets more affection and approval when his parents like his response. Then other adults reward some actions and criticize others. If one is to maintain the support of others and his own self-respect, he must adopt responses his social group approves.In finding trial responses, the learner does not choose models at random. He imitates the person who seems a good person to be like, rather than a person whose social status he wishes to avoid. If the pupil wants to be a good violinist, he will observe and try to copy the techniques of capable players; while some other person may most influence his approach to books.Admiration of one quality often leads us to admire a person as a whole, and he becomes an identifying figure. We use some people as models over a wide range of situation, imitating much that they do. We learn that they are dependable and rewarding models because imitating them leads to success.1. For a child the first element in his learning by imitation is ________.2. Apart from achieving his desired results, a child should also learn to ________.3. Children tend to imitate their models ________.4. “An identifying figure” (Para. 5) refers to a person ________.问题1选项A.the need to find an authorityB.the need to find a way to achieve the desired resultC.the need for more affection from his parentsD.the desire to meet the standards of his social group问题2选项A.behave properlyB.attain his goal as soon as possibleC.show his affection for his parentsD.talk quietly问题3选项A.who do not criticize themB.who bring them unexpected rewardsC.whom they want to be likeD.whose social status is high问题4选项A.who serves as a model for othersB.who is always successfulC.who can be depended uponD.who has been rewarded for his success【答案】第1题:B第2题:A第3题:C第4题:A【解析】第1题:【选项释义】For a child the first element in his learning by imitation is ________. 对孩子来说，模仿式学习的第一个因素是________。

Well, the good news is that, if you 41 some simple steps, taking English language exams can be really quite 42 . It won't exactly be fun, but it certainly shouldn't give you too many headaches or sleepless nights.If you are planning to 43 one of the well-known exams such as Cambridge First Certificate, you will probably find that there's a preparation course 44 at a school near you. Check that the school has a good 45 of exam success and that the teacher is 46 . It is a good idea to ask if you will be given homework and 47 your written work will be marked by a teacher who knows the level of English 48 by the exam.If you take an exam preparation course your teacher will give you all the information you need and you will find that 49 in a class helps you to study more effectively.

A segment of them are considered to be both educational and harmlessly entertaining. One such game teaches geography, and another trains pilots. Others train the player in logical thinking and problem solving. Some games may also help young people to become more computer literate, which is more important in this technology-driven era.But the dark side of the computer games has become more and more obvious. "A segment of games features anti-social themes of violence, sex and crude language," says David Walsh, president of the National Institute on Media and Family. "Unfortunately, it's a segment that seems particularly popular with kids aged eight to fifteen." One study showed that almost 80 percent of the computer and online games young people preferred contained violence. The investigators said "These are not just games anymore. These are learning machines. We're teaching kids in the most incredible manner what it's like to pull the trigger. What they are not learning are the real-life consequences."They also said "The new and more sophisticated games are even worse, because they have better graphics and allow the player to participate in even more realistic violent acts." In the game Carmageddon, for example, theplayer will have driven over and killed up to 33,000 people by the time all levels are completed. A description of the outcome of the game says: "Your victims not only squish under your tires and splatter blood on the windshield, they also get on their knees and beg for mercy, or commit suicide. If you like, you can also dismember them."Is all this simulated violence harmful? Approximately 3,000 different studies have been conducted on this subject. Many have suggested that there is a connection between violence in games and increased aggressiveness in the players.Some specialists downplay the influence of the games, saying that other factors must be taken into consideration, such as the possibility that kids who already have violent tendencies are choosing such games. But could it be that violent games still play a contributing role? It seems unrealistic to insist that people are not influenced by what they see. If that were true, why would the commercial world spend billions of dollars annually for television advertising?51. Which of the following computer games is NOT mentioned as educational and harmlessly entertaining?A. Those that help people learn more about computers.B. Those that teach the features of the earth.C. Those that provide special training for writers online.D. Those that provide special training for pilots.52. According to one study, most computer and online gamesA. allow the players to take part in killing actsB. teach the players to be antisocialC. make the players forget the real life resultsD. that young people like contain violence53. What does the underlined word "dismember" in Paragraph 4 mean?A. To kick somebody out.B. To cut somebody into pieces.C. To dismiss somebody.D. To stab a knife into somebody.54. Many studies have suggested that____________.A. more and more young people enjoy cruel computer gamesB. violence in computer games makes their players more aggressiveC. there are now far more incidents of violence due to computer gamesD. simulated violence in computer games is different from real violence55. The author uses “television advertising” as an example to show that____________.A. other factors must be considered as possible causes of violence in real lifeB. computer and online games are not the only cause of increased violence in real lifeC. the commercial world is contributing to the increased violence in real lifeD. there is a close link between computer games and increased violence in real life56. The best title for the passage is___________.A. The Dark Side of Computer GamesB. Computer Games--Advantages and DisadvantagesC. The Development of Violent Computer GamesD. A Study on the Influence of Computer GamesPassage TwoThe collapse of the Earth's magnetic field---which guards the planet and guides many of its creatures--appears to have started seriously about 150 years ago, the New York Times reported last week.The field's strength has decreased by 10 or 15 per cent so far and this has increased the debate over whether it signals a reversal of the planet's lines of magnetic force.During a reversal, the main field weakens, almost vanishes, and reappears with opposite polarity. The transition would take thousands of years. Once completed, compass needles that had pointed north would point south. A reversal could cause problems for both man and animals. Astronauts and satellites would have difficulties. Birds, fish and animals that rely on the magnetic field for navigation would find migration confusing. But experts said the effects would not be a big disaster, despite claims of doom and vague evidence of links between past field reversals and species extinctions.Although a total transition may be hundreds or thousands of years away, the rapid decline in magnetic strength is already affecting satellites. Last month, the European Space Agency approved the world's largest effort at tracking the field's shifts. A group of new satellites, called Swarm, is to monitor the collapsing field with far greater precision. "We want to get some idea of how this would evolve in the near future, just like people trying to predict the weather," said Ganthier Hulot, a French geophysicist working on the satellite plan. "I'm personally quite convinced we should be able to work out the first predictions by the end of the mission."No matter what the new findings, the public has no reason to panic. Even if a transition is coming on its way, it might take 2,000 years to mature. The last one took place 780,000 years ago, when early humans were learning how to make stone tools. Deep inside the Earth flow hot currents of melted iron. This mechanical energy creates electromagnetism. This process is known as the geophysical generator. In a car's generator, the same principle turns mechanical energy into electricity.No one knows precisely why the field periodically reverses. But scientists say the responsibility probably lies with changes in the disorderly flows of melted iron, which they see as similar to the gases that make up the clouds of Jupiter.57. According to the passage, the Earth's magnetic field has ____________.A. begun to change in the opposite directionB. been weakening in strength for a long timeC. caused the changes on the polaritiesD. misguided many a man and animal58. During the transition of the Earth's magnetic field _____________.A. the compass will become uselessB. man and animals will be confused as to directionsC. the magnetic strength of the Earth will disappearD. the magnetic strength of the Earth will be stronger59. According to the experts, the reversal of the Earth's magnetic field would ____________.A. destroy almost all the creatures on the EarthB. cause some species extinctions on the EarthC. not be as disastrous as the previous oneD. cause no big trouble for man and animals60. According to the passage,_____________.A. we should not worry about the transition of the Earth's magnetic fieldB. the Earth's magnetic field will not change for at least 2,000 yearsC. the Earth's magnetic field has decreased its strength rapidlyD. the transition of the Earth's magnetic field can be controlled by modem science61. The author says "...the public has no reason to panic" because_______________.A. the transition is still thousands of years awayB. the new transition will come 780,000 years from nowC. the transition can be precisely predicted by scientistsD. the process of the transition will take a very long time to finish62. The transition of the Earth's magnetic field is possibly caused by____________.A. the flows of melted iron inside the EarthB. the periodical movement of the EarthC. the mechanical energy of the solar systemD. the force coming from outer spacePassage ThreeThe terrorist attacks in London Thursday served as a stunning reminder that in today's world, you never know what you might see when you pick up the newspaper or turn on the TV. Disturbing images of terror can trigger an instinctive response no matter how close or far away from home the event happened.Throughout history, every military conflict has involved psychological warfare in one way or another as the enemy sought to break the morale of their opponent. But thanks to advances in technology, the popularity of the Internet, and proliferation of news coverage, the roles of engagement in this type of mental battle have changed.Whether it's a massive attack or a single horrific act, the effects of psychological warfare aren't limited to the physical damage inflicted. Instead, the goal of these attacks is to instill a sense of fear that is much greater than the actual threat itself.Therefore, the impact of psychological terror depends largely on how the acts are publicized and interpreted. But that also means there are ways to defend yourself and your loved ones by putting these fears into perspective and protecting your children from horrific images.What Is Psychological Terror? “The use of terrorism as a tactic is based upon inducing a climate of fear that is disproportionate: with the actual threat," says Middle Eastern historian Richard Bulliet of Columbia University. "Every time you have an act of violence, publicizing that violence becomes an important part of the act itself.""There are various ways to have your impact. You can have your impact by the magnitude of what you do, by the symbolic character of target, or the horrific quality of what you do to a single person," Bulliet tells WebMD. "The point is that it isn't what you do, but it's how it's covered that determines the effect." For example, Bulliet says the Iranian hostage crisis, which began in 1979 and lasted for A A.4 days, was actually one of the most harmless things that happened in the Middle East in the last 25 years. All of the U.S. hostages were eventually released unharmed, but the event remains a psychological scar for many Americans who watched helplessly as each evening's newscast counted the days the hostages were being held captive.Bulliet says terrorists frequently exploit images of a group of masked individuals exerting total power over their captives to send the message that the act is a collective demonstration of the group's power rather than an individual criminal act. "You don't have the notion that a certain person has taken a hostage. It's an image of group power, and the force becomes generalized rather than personalized," says Bulliet. "The randomness and the ubiquity of the threat give the impression of vastly greater capacities."Psychiatrist Ansar Haroun, who served in the U.S. Army Reserves in the first Gulf War and more recently in Afghanistan, says that terrorist groups often resort to psychological warfare because it's the only tactic they have available to them. "They don't have M-16s, and we have M-16s. They don't have the mighty military power that we have, and they only have access to things like kidnapping," says Haroun, who is also a clinical professor of psychiatry at the University of California, San Diego."In psychological warfare, even one beheading (斩首) can have the psychological impact that might be associated with killing 1,000 of the enemy," Haroun tells WebMD. "You haven't really harmed the enemy very much by killing one person on the other side. But in terms of inspiring fear, anxiety, terror, and making us all feel bad, you've achieved a lot of demoralization."63. What has changed the rules of psychological warfare?A. Terrorist attacks.B. The increase of military conflicts.C. Advances in nuclear weapons.D. Prosperity of the media.64. The goal of psychological warfare is to____________.A. change the ideology of the opponentB. win a battle without military attacksC. generate a greater sense of fearD. bring about more physical damage65. According to Richard Bulliet, publicizing an act of violence becomes an important part of terrorism itself because__________.A. psychological terrorism is a tacticB. terrorism depends on a climate of fear rather than on the actual threatC. the use of terrorism is to inspire fear that is more destructive than the actual threatD. publicizing the violence can make more people know the actual threat66. The Iranian hostage crisis shows that___________.A. means determines effectsB. hostage crises are prevalentC. psychological terrors remain harmlessD. the American media is effective67: Terrorists hold an individual as a hostage to _____________.A. scare the publicB. demonstrate their crueltyC. manipulate the government concernedD. show their group power68. In this passage the author___________.A. emphasizes the great impact of psychological warfareB. criticizes the violence of terrorismC. calls for an end to psychological warfareD. opposes the hostage crisisPassage FourIn a year marked by uncertainty and upheaval, officials at New Orleans universities that draw applicants nationwide are not following the usual rules of thumb when it comes to college admissions. The only sure bet, they say, is that this fall's entering classes—the first since Katrina--will be smaller than usual.In typical years, most college admissions officials can predict fairly accurately by this point in the admissions cycle how many high school seniors will commit to enrolling in their institutions. Many of the most selective schools require students—who increasingly are applying to mt,'ltiple institutions--to make their choices by May 1. Loyola University, whose trustees will vote May 19 on whether to drop several degree programs and eliminate 17 faculty positions, received fewer applications--about 2,900 to date, compared with 3,500 in recent years. The school hopes to enroll 700 freshmen, down from 850 in the past few years. Historically black Dillard University, which is operating out of a hotel and was forced to cancel its annual March open house, also saw drops, as did Xavier University, a historically black Catholic institution that fell behind its recruitment schedule. Dillard won't release numbers, but spokeswoman Maureen Larkins says applications were down and enrollments are expected to be lower than in the past. Xavier admissions dean Winston Brown says its applicant pool fell by about half of last year's record 1,014; he hopes to enroll 500 freshmen.In contrast, Tulane University, which is the most selective of the four and developed an aggressive recruitment schedule after the hurricane, enjoyed an 11% increase in applications this year, to a record 20,715. Even so, officials predict that fewer admitted students will enroll and are projecting a smaller-than-usual freshman class--l,400, compared with a more typical 1,600. Tulane officials announced in December that they would eliminate some departments and faculty positions.Like Tulane, other schools are taking extra steps this year to please admitted students, often by enlisting help from alumni (校友会) around the country and reaching out to students with more e-mail, phone calls or Web-based interactions such as blogs. In addition, Loyola is relaxing deadlines, sweetening the pot with larger scholarships and freezing tuition at last year's level. Dillard, too, is freezing tuition. It's also hosting town meetings in target cities and regions nationwide, and moved its academic calendar back from August to mid-September "to turn away from the majority of the hurricane season," Larkins says. Xavier extended its application deadline and stepped up its one-on-one contact with accepted students. And Tulane, among other things, has doubled the number a hurricane of on-campus programs for accepted students and hosted a community service weekend program.While the schools expect applicants to be apprehensive, the admissions officials also see encouraging signs of purposefulness among applicants. "A lot of students who are choosing to come to this city are saying, 'I want to be a part of the action,'" says Stieffel, noting that Loyola's transfer applications were up 30%. And while applications to Xavier are down, Brown is betting that students who do apply are serious. "The ones who are applying, we feel, are more likely to come," he says.69. The word "Katrina" in Para. 1 probably refers to_____________.A. a hurricaneB. an admission officialC. a universityD. a student70. It can be learned from the passage that__________.A. most colleges require students to apply and commit to their institutionsB. more students are applying to multiple institutionsC. all students are required to make their institution choices by May 1D. university trustees make decisions on enrollment.71. The following statements are all true EXCEPT_________________.A. Tulane University also saw drops in applications this yearB. Xavier University fell behind its recruitment scheduleC. applicants to Xavier university fell by about half of last year's recordD. Loyola University will vote on whether to eliminate 17 faculty positions72. In order to attract applicants, Loyola University and Dillard University are both_________.A. freezing tuitionsB. extending application deadlinesC. hosting meetingsD. increasing scholarships73. Tulane University enjoyed an increase in applicants due to its__________.A. new enrollment policiesB. aggressive recruitment scheduleC. academic positionD. financial situation74. The passage is mainly concerned with____________.A. the drops of the applicants of universitiesB. the dilemma of the admission officialsC. the usual rules of college admissionsD. the effects of the hurricanePassage FiveA store exposure to crime does not diminish when the store is closed. On the contrary, as night falls, criminals are on the move looking for the best crime opportunity. This period of time is, in fact, critical. Owners generally rely only on the presence of physical barriers and electronic security. But they do not seem to be able to stop a determined effort by a group of professional criminals.When closed, commercial stores can be attacked in many different ways such as:Three-minute burglary. It involves attacking a glass front door or a window at night, smashing a display case, and stealing merchandise left out of safes. This type of criminals has little concern about the alarm system: They intend to be gone before any reaction is made to the alarm signal. In the United States, this type of burglary represents nearly 75% of all the burglary events in the jewelry industry.Ramming. It means driving into a store by smashing the front windows or doors. It has also been a practice used by criminals to gain access to valuable merchandise.Safecracking. It involves attacking a safe and stealing its contents. It should not be left out as a risk for store owners, but it makes up for a very small percentage of closed store crimes. This type of crime is decreasing as a result of the high security safes and alarm systems.Robbery is not frequent during closing time, but always represents a threat to store owners. Criminals may in fact decide to take them (or family members) hostage when at home and force them back to the store.To reduce the risks for a closed store crime to occur, the following reduction strategies are recommended:Safes. Time locks on safes, which allow opening only at specified times, can be considered as an added source of protection. Making use of different safes for high value merchandise can also reduce potentially heavy losses.Exterior and interior lighting. This is essential, as it remains one of the most effective weapons against burglary, theft and armed robbery. Lights should be positioned at strategic points and exterior lights should be protected against damage.Security systems. Detection and security systems are extremely important. Another interesting device is the smoke screen system. Once activated, this system, within seconds, fills a small area with a thick but harmless smoke, thus preventing criminals from seeing and forcing them to flee.75. A store exposed to crime at day time __________.A. is less likely to be attacked with the presence of physical barriers at nightB. seems to invite a group of professional criminals at nightC. creates the best crime opportunity at nightD. is more likely to be broken into at night。
