Part 3. Reading Comprehension (Multiple Choice)

Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D.

Questions 71 to 75 are based on the following passage.

In the primary school, a child is in a comparatively simple setting and most of the time forms a relationship with

one familiar teacher. On entering secondary school, a new world opens up and frequently it is a much more difficult world. The pupil soon learns to be less free in the way he speaks to teachers and even to his fellow pupils. He begins to lose gradually the free and easy ways of the primary school, for he senses the need for a more cautious approach in the secondary school where there are older pupils. Secondary staff and pupils suffer from the pressures of academic work and seem to have less time to stop and talk. Teachers with specialist roles may see hundreds of children in a week, and a pupil may be able to form relationships with very few of the staff. He has to decide which adults are approachable; good schools will make clear to every young person from the first year what guidance and personal help is available—but whether the reality of life in the institution actually encourages requests for help is another matter.

Adults often forget what a confusing picture school can offer to a child. He sees a great deal of movement, a great number of people—often rather frightening-looking people—and realizes that an increasing number of choices and decisions have to be made. As he progresses through the school the confusion may become less but the choices and decisions required will increase. The school will rightly expect the pupil to take the first steps to obtain the help he needs, for this is the pattern of adult life for which he has to be prepared, but all the time the opportunities for personal and group advice must be presented in a way which makes them easy to understand and within easy reach of pupils.

71. According to the passage one of the problems for pupils entering secondary schools is that ________.

A. they are taught by many different teachers

B. they do not attend lessons in every subject

C. the teachers are not so friendly and helpful

D. the teachers give most attention to a few pupils

72. In secondary schools every pupil having problems should ________.

A. know how to ask for help

B. go to ask any teacher he can find

C. discuss his problem in class

D. turn to his parents for help

73. It can be inferred from the passage that the author is mainly concerned about ________.

A. academic standards

C. the training of the individual teachers

D. the personal development of pupils

74. Which of the following statements is TRUE?

A. All the secondary schools know the way to encourage students' requests for help.

B. The secondary schools are responsible for offering personal and group advice to new pupils.

C. Secondary school pupils enjoy greater freedom in communicating with teachers and fellow pupils.

D. Secondary school pupils can easily get the help they need.

75. The most appropriate title for the passage is ________.

A. Primary School and Secondary School

B. Problems for New Secondary School Teachers

C. Problems for New Secondary School Pupils

D. Academic Work and Personal Relationship Questions 76 to 80 are based on the following passage.

The US military has blocked public access to nearly all its web sites after its servers were attacked by a new computer virus.

Late last week, the US Space Command, which provides security for military computers, instructed all military organizations to block public access after a number of sites had contracted the virus, called the "Code Red" bug, according to an official.

The virus is known as a "denial of service" bug, because it replicates (自我复制) itself by reading the data files on a network server and sending copies to other servers—thereby multiplying and sometimes crashing a system—and denying access to legitimate (合法的) users of the site.

"The Code Red worm did in fact show up in some DoD (Department of Defense) web sites and we're working to contain that," Command Spokesman Army Maj. Barry Venable said. "Ways we're going about that include blocking public access to the Web sites, because that's the way this worm works, to prevent it from using our networks to propagate (繁殖) itself."

The virus exploits a security flaw (缺陷) in certain Microsoft network servers. The flaw was announced last month when a patch was released to fix it.

"To protect our DoD web sites from being compromised, DoD organizations have been told to review the status of the Internet information servers... to make sure that all the patches that were previously installed had been installed," says Venable.

Only a handful of the major Defense Department sites, with the suffix ".mil," appear currently accessible to the public, including the central public affairs site DefenseLink and the military services' main homepages. Public access is blocked to information connected to those sites, and others such as the National Missile Defense site and the US Air Force's European site. Registered Department of Defense personnel continue to have access to the sites, Venable said.

76. Which of the following is the best title for this passage?

A. The Code Red Worm.

B. DoD Blocks Public Web Site Access.

C. DoD Was Attacked.

D. Protect DoD Web Sites Against Viruses.

77. The word "contracted" (Para.2) most probably means ________.

A. make less or smaller

B. get an illness

C. make a legal agreement

D. formally agree to marry somebody

78. Which of the following statements is NOT true about the Code Red worm?

A. It can multiply in large numbers.

B. It may make a computer system stop working.

C. It's included in a patch released by Microsoft.

D. It may destroy the connection between legitimate users and the sites.

79. Public access is blocked to most DoD web sites so that ________.

A. the Code Red worm can't use the web site to replicates itself and send copies

B. DoD organizations can have necessary patches installed to protect their sites

C. the defense secrets can be prevented from being revealed

D. the mistake in certain Microsoft network servers can be corrected

80. Which of the following is NOT a measure taken by DoD to fight against the Code Red worm?

A. Blocking public access.

B. Shutting down e-mail.

C. Reviewing the status of the Internet information servers.

D. Having necessary patches installed. Questions 81 to 85 are based on the following passage.

The decline in moral standards—which has long concerned social analysts—has at last captured the attention of average Americans. And Jean Bethke Elshtain, for one, is glad.

The fact that ordinary citizens are now starting to think seriously about the nation's moral climate, says this ethics (伦理学) professor at the University of Chicago, is reason to hope that new ideas will come forward to improve it.But the challenge is not to be underestimated. Materialism and individualism in American society are the biggest obstacles. "The thought that 'I'm in it for me' has become deeply rooted in the national consciousness," Ms. Elshtain says.Some of this can be attributed to the decay of traditional communities, in which neighbors looked out for one another, she says. With today's greater mobility and with so many couples working, those bonds have been weakened, replaced by a greater emphasis on self.

In a 1996 poll of Americans, loss of morality topped the list of the biggest problems facing the US. And Elshtain says the public is correct to sense that: Data show that Americans are struggling with problems unheard of in the 1950s, such as classroom violence and a high rate of births to unmarried mothers.

The desire for a higher moral standard is not a lament (挽歌) for some nonexistent "golden age," Elshtain says, nor is it a wishful (一厢情愿的) longing for a time that denied opportunities to women and minorities. Most people, in fact, favor a decrease in prejudice.

Moral decline will not be reversed until people find ways to counter the materialism in society, she says. "Slowly, you recognize that the things that matter are those that can't be bought."

81. Professor Elshtain is pleased to see that Americans ________.

A. have adapted to a new set of moral standards

B. are longing for the return of the good old days

C. have realized the importance of material things

D. are awakening to the lowering of their moral standards

82. The moral decline of American society is caused mainly by ________.

A. its growing wealth

B. the self-centeredness of individuals

C. underestimating the impact of social changes

D. the prejudice against women and minorities

83. Which of the following characterizes the traditional communities?

A. Great mobility.

B. Emphasis on individual effort.

C. Concern for one's neighbors.

D. Ever-weakening social bonds.

84. In the 1950s, classroom violence ________.

A. was something unheard of

B. attracted a lot of public attention

C. was by no means a rare occurrence

D. began to appear in analysts' data

85. According to Elshtain, the current moral decline may be reversed ________.

A. if people can return to the "golden age"

B. when women and men enjoy equal rights

C. when people rid themselves of prejudice

D. if less emphasis is laid on material things

Part 3. Reading Comprehension (Multiple Choice)

Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D.

Questions 56 to 60 are based on the following passage.

During the first half of the nineteenth century much thought was given to building the Panama Canal. The discovery of gold in California in 1848 brought an increased demand for a transportation link across Panama. A railroad line was completed after six years of hard labor in the swamps (沼泽) and jungles. Over two thousand workmen died from yellow fever and malaria (疟疾). In 1881 a French organization tried to build a canal across the Isthmus (巴拿马地峡). For eleven years workmen struggled against heat and disease. At least 15,000 died before the French gave up their attempts to build the canal. For years the abandoned machinery lay in the jungles. At the close of the Spanish-American War the United States bought a strip of land ten miles wide across the Isthmus. Immediate attention was given to the control of diseases. In two years yellow fever was completely eliminated. Because of the work of American medical heroes, it was possible to build the splendid Panama Canal.

At one time a traveler could learn about a region by looking at the houses. For example, he or she could understand what building materials were available. In areas with many wood houses, the traveler would have guessed that there were nearby forests. Stone houses would have indicated that stones were easy to get. However, a closer look at the houses would have told the traveler even more about the area.

People used to build houses that fitted the climate of their areas. For example, in desert regions there is a big difference between daytime and nighttime temperatures. Therefore, many desert people built houses with very thick walls. These thick walls served a useful purpose in the houses. For example, in the winter the thick walls absorbed the sun's warmth during the day and radiated the heat at night. Desert people were relatively comfortable in their homes, or residences, at all times because they built them to fit the desert climate.

Then the supply of fuel for electricity became both cheap and easy to get. The effect on housing was immediate. People began to build their homes according to fashion instead of utility. Houses no longer reflected the availability of building materials or climate.

Houses with steep roofs could be found in the tropics, the warm regions of the Earth, even though these pointed roofs originated in snowy regions of the world. Heavy snow falls off a slanted (歪斜的) roof. Another example is the use of glass. Houses made almost completely of glass could be found in very cold places. Yet ordinary glass does not insulate (绝缘) well because it neither keeps out cold air nor keeps in warm air. As long as fuel was cheap and easy to get, people could build any type of house any place.

Questions 66 to 70 are based on the following passage..

Real policemen, both in Britain and the United States, hardly recognize any resemblance (相似) between

their lives and what they see on TV-if they are even able to watch TV.

The first difference is that in real life a policeman has been trained in criminal law. He has to know exactly

what actions are crimes and what evidence can be used to prove them in court.

He will spend most of his working life typing millions of words on thousands of forms about hundreds

of sad, unimportant people who are guilty-or not-of stupid, petty (不重要的) crimes.

Most television crime drama is about finding the criminal: as soon as he's arrested, the story is over. In real life, finding criminals is seldom much of a problem. Except in very serious cases like murders and terrorist attacks-where failure to produce results reflects on the standing of the police-little effort is spent on searching.

A third big difference is between the drama detective and the real life ones. Detectives are subject to two opposing pressures: first, as members of a police force they always have to behave with absolute legality (合法); secondly, as expensive public servants they have to get results. They can hardly ever do both. Most of the time some of them have to break the rules in small ways.

If the detective has to deceive the world, the world often deceives him. Hardly anyone he meets tells him the truth. And this separation the detective feels between himself and the rest of the world is deepened by the simplemindedness-as he sees it-of citizens, social workers, doctors, law-makers, and judges, who, instead of stamping out crime, punish the criminals less severely in the hope that this will make them reform. The result, detectives feel, is that nine-tenths of their time is spent re-catching people who should have stayed behind bars. This makes them rather cynical.

66. It is essential for a policeman to be trained in criminal law ________.

A. so that he can catch criminals in the streets

B. because many of the criminals he has to catch are dangerous

C. so that he can justify his arrests in court

D. because he has to know nearly as much about law as a professional lawyer

67. The everyday life of a policeman or detective is ________.

A. exciting and mysterious

B. full of danger

C. devoted mostly to routine matters

D. wasted on unimportant matters

68. When murders and terrorist attacks occur the police ________.

A. prefer to wait for the criminal to give himself away

B. work hard to track down the criminals

C. try to make a quick arrest in order to keep up their reputation

D. usually fail to produce results

69. The real detective lives in an unusual moral climate because ________.

A. he is an expensive public servant

B. he must always behave with absolute legality

C. he is obliged to break the law in order to preserve it

D. he feels himself to be cut off from the rest of the world

70. Detectives are rather cynical because ________.

A. nine-tenths of their work involves arresting people

B. hardly anyone tells them the truth

C. society does not punish criminals severely enough

D. D too many criminals escape from jail
