Part II Reading Comprehension (35 minutes)
Directions:There are 4 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Questions 21 to 25 are based on the following passage.
In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn't any crime to worry about.
Amazingly, these happy times appear still to be with us in the world's biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors.
SATAN can try out a variety of well-known hacking (黑客的) tricks on an Internet site with-out actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle (闯入……行窃).
But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.
So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.
At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage.
But let's look on the bright side. Given the lack of locks, the Internet is surely the world's biggest (almost) crime-free society. Maybe that is because hackers are fundamentally honest. Or that there currently isn't much to steal. Or because vandalism ( 恶意破坏) isn't much fun unless you have a peculiar dislike for someone.
Whatever the reason, let's enjoy it while we can. But expect it all to change, and security to become the number one issue, when the most influential inhabitants of the Net are selling services they want to be paid for.
21. By saying "…… owners of well over half of all World Wide Web sites have set up home without fitting locks to their doors" (Lines 3-4, Para. 2), the author means that _____.
A) those happy times appear still to be with us
B) there simply wasn't any crime to worry about
C) many sites are not well-protected
D) hackers try out tricks on an Internet site without actually breaking in
22. SATAN, a program designed by Dan Fanner can be used ____________.
A) to investigate the security of Internet sites
B) to improve the security of the Internet system
C) to prevent hackers from breaking into websites
D) to download useful programs and information
23. Fanner's program has been criticized by the public because.
A) it causes damage to Net browsers
B) it can break into Internet sites
C) it can be used to cause disorder on all sites
D) it can be used by people with evil intent
24. The author's attitude toward SATAN is _____.
25. The author suggests in the last paragraph that.
A) we should make full use of the Internet before security measures are strengthened
B) we should alert the most influential businessmen to the importance of security
C) influential businessmen should give priority to the improvement of Net security
D) net inhabitants should not let security measures affect their joy of surfing the Internet
Questions 26 to 30 are based on the following passage.
I came away from my years of teaching on the college and university level with a conviction that enactment (扮演角色), performance, dramatization are the most successful forms of teach-ing. Students must be incorporated, made, so far as possible, an integral part of the learning pro-cess. The notion that learning should have in it an element of inspired play would seem to the greater part of the academic establishment merely silly, but that is nonetheless the case. Of Ezekiel Cheever, the most famous schoolmaster of the Massachusetts Bay Colony, his onetime student Cotton Mather wrote that he so planned his lessons that his pupils "came to work as though they came to play," and Alfred North Whitehead, almost three hundred years later, noted that a teacher should make his/her students "glad they were there."
Since, we are told, 80 to 90 percent of all instruction in the typical university is by the lecture method, we should give close attention to this form of education. There is, I think, much truth in Patricia Nelson Limerick's observation that "lecturing is an unnatural act, an act for which God did not design humans. It is perfectly all right, now and then, for a human to be possessed by the urge to speak, and to speak while others remain silent. But to do this regularly, one hour and 15 minutes at a time …… for one person to drag on while others sit in silence? …… I do not believe that this is what the Creator …… designed humans to do."
The strange, almost incomprehensible fact is that many professors, just as they feel obliged to write dully, believe that they should lecture dully. To show enthusiasm is to risk appearing unscientific, unobjective; it is to appeal to the students' emotions rather than their intellect. Thus the ideal lecture is one filled with facts and read in an unchanged monotone.
The cult (推崇) of lecturing dully, like the cult of writing dully, goes back, of course, some years. Edward Shils, professor of sociology, recalls the professors he encountered at the University of Pennsylvania in his youth. They seemed "a priesthood, rather uneven in their merits but uniform in their bearing; they never referred to anything personal. Some read from old lecture notes and then haltingly explained the thumb-worn last lines. Others lectured from cards that had served for years, to judge by the worn edges …… The teachers began on time, ended on time, and left the room without saying a word more to their students, very seldom being detained by questioners …… The classes were not large, yet there was no discussion-. No questions were raised in class, and there were no office hours."
26. The author believes that a successful teacher should be able to _____.
A) make dramatization an important aspect of students' learning
B) make inspired play an integral part of the learning process
C) improve students' learning performance
D) make study just as easy as play
27. The majority of university professors prefer the traditional way of lecturing in the belief that _________________.
A) it draws the close attention of the students
B) it conforms in a way to the design of the Creator
C) it presents course content in a scientific and objective manner
D) it helps students to comprehend abstract theories more easily
28. What the author recommends in this passage is that _________.
A) college education should be improved through radical measures
B) more freedom of choice should be given to students in their studies
C) traditional college lectures should be replaced by dramatized performances
D) interaction should be encouraged in the process of teaching
29. By saying "They seemed 'a priesthood, rather uneven in their merits but uniform in their bearing……'" (Lines 3-4, Para. 4), the author means that _____.
A) professors are a group of professionals that differ in their academic ability but behave in the same way
B) professors are like priests wearing the same kind of black gown but having different roles to play
C) there is no fundamental difference between professors and priests though they differ in their merits
D) professors at the University of Pennsylvania used to wear black suits which made them look like priests
30. Whose teaching method is particularly commended by the author?
A) Ezekiel Cheever's.
B) Cotton Mather's.
C) Alfred North Whitehead's.
D) Patricia Nelson Limerick's.
Questions 31 to 35 are based on the following passage.
Take the case of public education alone. The principal difficulty faced by the schools has been he tremendous increase in the number of pupils. This has been caused by the advance of the legal age for going into industry and the impossibility of finding a job even when the legal age has been reached. In view of the technological improvements in the last few years, business will require in he future proportionately fewer workers than ever before. The result will be still further raising of he legal age for going into employment, and still further difficulty in finding employment when hat age has been attained. If we cannot put our children to work, we must put them in school.
We may also be quite confident that the present trend toward a shorter day and a shorter week will be maintained. We have developed and shall continue to have a new leisure class. Already the public agencies for adult education are swamped by the tide that has swept over them since depression began. They will be little better off when it is over. Their support must come from the taxpayer.
It is surely too much to hope that these increases in the cost of public education can be borne by the local communities. They cannot care for the present restricted and inadequate system. The local communities have failed in their efforts to cope with unemployment. They cannot expect to cope with public education on the scale on which we must attempt it. The answer to the problem of unemployment has been Federal relief. The answer to the problem of public education may have to be much the same, and properly so. If there is one thing in which the citizens of all parts of the country have an interest, it is in the decent education of the citizens of all parts of the country. Our income tax now goes in part to keep our neighbors alive. It may have to go in part as well to make our neighbors intelligent. We are now attempting to preserve the present generation through Federal relief of the destitute (贫民). Only a people determined to ruin the next generation will refuse such Federal funds as public education may require.
31. What is the passage mainly about?
A) How to persuade local communities to provide more funds.
B) How to cope with the shortage of funds for public education.
C) How to solve the rising unemployment problem.
D) How to improve the public education system.
32. What is the reason for the increase in the number of students?
A) The requirement of educated workers by business.
B) Raising of the legal age for going to work.
C) The trend toward a shorter workday.
D) People's concern for the future of the next generation.
33. The public agencies for adult education will be little better off because _____.
A) the unemployed are too poor to continue their education
B) a new leisure class has developed
C) they are still suffering from the depression
D) an increase in taxes could be a problem
34. According to the author, the answer to the problem of public education is that the Federal government _____. .
A) should allocate Federal funds for public education
B) should demand that local communities provide support
C) should raise taxes to meet the needs of public education
D) should first of all solve the problem of unemployment
35. Why does the author say "Only a people determined to ruin the next generation will refuse such Federal funds as public education may require" (Lines 10-11, Para. 3)?
A) Only by appropriating adequate Federal funds for education can the next generation have a bright future.
B) Citizens of all parts of the country agree that the best way to support education is to use Federal funds.
C) people all over the country should make contributions to education in the interest of the next generation.
D) Educated people are determined to use part of the Federal funds to help the poor.
Questions 36 to 40 are based on the following passage.
A new high-performance contact lens under development at the department for applied phys-ics at the University of Heidelberg will not only correct ordinary vision defects but will enhance normal night vision as much as five times, making people's vision sharper than that of cats.
Bille and his team work with an optical instrument called an active mirror - a device used in astronomical telescopes to spot newly emerging stars and far distant galaxies. Connected to a wave-front sensor that tracks and measures the course of a laser beam into the eye and back, the aluminum mirror detects the deficiencies of the cornea, the transparent protective layer covering the lens of the human eye. The highly precise data from the two instruments - which, Bille hopes, will one day be found at the opticians (眼镜商) all over the world - serve as a basis for the production of completely individualized contact lenses that correct and enhance the wearer's vision.
By day, Bille's contact lenses will focus rays of light so accurately on the retina （视网膜）that the image of a small leaf or the outline of a far distant tree will be formed with a sharpness that surpasses that of conventional vision aids by almost half a diopter ( 屈光度). At night, the lenses have an even greater potential. "Because the new lens - in contrast to the already existing ones - also works when it's dark and the pupil is wide open," says Bille, "lens wearers will be able to identify a face at a distance of 100 meters" - 80 meters farther than they would normally be able to see. In his experiments night vision was enhanced by an even greater factor: in semi-darkness, test subjects could see up to 15 times better than without the lenses.
Bille's lenses are expected to reach the market in the year 2000, and one tentative plan is to use the Internet to transmit information on patients' visual defects from the optician to the manufac-turer, who will then produce and mail the contact lenses within a couple of days. The physicist expects the lenses to cost about a dollar a pair, about the same as conventional one-day disposable lenses.
36. The new contact lens is meant for _____________.
A) astronomical observations
B) the night blind
C) those with vision defects
D) optical experiments
37. What do the two instruments mentioned in the second paragraph (Line 5) refer to?
A) The astronomical telescope and the wave-front sensor.
B) The aluminum mirror and the laser beam.
C) The active mirror and the contact lens.
D) The aluminum mirror and the wave-front sensor.
38. Individualized contact lenses (Line 7, Para. 2) are lenses designed _____.
A) to work like an astronomical telescope
B) to suit the wearer's specific needs
C) to process extremely accurate data
D) to test the wearer's eyesight
39. According to Bille, with the new lenses the wearer's vision _____.
A) will be far better at night than in the daytime
B) may be broadened about 15 times than without them
C) can be better improved in the daytime than at night
D) will be sharper by a much greater degree at night than in the daytime
40. Which of the following is true about Bille's lenses?
A) Their production process is complicated.
B) They will be sold at a very low price.
C) They have to be replaced every day.
D) Purchase orders can be made through the Internet.

Ownership of Houses in a Big City in China
As can be seen from the chart, ownership of houses in Beijing has significantly changed in the 1990s. In 1990, 75 percent of the houses were state-owned. Five years later, the ratio of state-owned houses to private ones was 60 to 40. But from then on, the ownership changed dramatically and by the end of the century, 80 percent of houses were private.
There might have been two main reasons. One of the reasons was the policy of the government. In the 1990s, China carried on with its reform policy and the government called for privatization of the sate-owned estate. But it took time for the reform to come into effect. But from 1995 on when people have recognized its significance, the reformation took bigger steps. Another reason was that the people were getting better off and they could afford buying their own houses.
Such changes have had great impact on individuals as well as the society. On one hand, the individuals must save money to buy an apartment or to pay the mortgage. On the other hand, a heaven burden has been taken off the government so that it can take more effective measures to improve people's life.

A few months ago, millions of people in London heard alarms all over the town. The Emergency Emergency services, the Fire Departments, the Police, hospitals, and ambulances stood by, ready to go into action. In railway underground stations, people read notices and maps which told them where to go and what to do in the emergency. This was Exercise Flood Call, to prepare people for a flood emergency. London wasn't flooded yet, but it is possible that it would be. In 1236 and in 1663, London was badly flooded. In 1928, people living in Westminster, the heart of London, drowned in floods. And in 1953, one hundred people, living on the eastern edge of the London suburbs were killed, again, in the floods. At last, Greater London Council took actions to prevent this disaster from happening again. Though a flood wall was built in the 1960s, Londoners still must be prepared for the possible disaster. If it happens, 50 underground stations will be under water. Electricity, gas and phone services will be out of action. Roads will be drowned. It will be impossible to cross any of the bridges between north and south London. Imagine: London will look like the famous Italian city, Venice. But this Exercise Flood Call didn't cause panic among Londoners. Most people knew it was just a warning. One lady said, "It's a flood warning, isn't it? The water doesn't look high to me."
Question 11: What happened in London a few months ago?
Question 12: What measure was taken against floods in London in the 1960s?
Question 13: What can we learnt from the lady's comment?
America's national symbol, the bald eagle, almost went extinct twenty years ago, but it has made a comeback. In fact, the U.S. Fish and Wild Life Service is considering the possibility of taking it off the Endangered Species List. Once, more than fifty hundred pairs of bald eagles nested across the country, but by 1960 that number had fallen below four hundred. The chief killer was the widely used DDT. Fish, soaked up DDT, died, and were washed up on shores, where bald eagles feasted on them.DDT prevented eagle egg shells from thickening. The shells became so thin that they shattered before the babies hatched. Fortunately, in 1972, a law was passed to ban DDT, which saved the bald eagle from total wipeout. And since then wild life biologists had reintroduced bald eagles from Canada to America. The result was that last year U.S. bird watchers counted eleven thousand six hundred and ten bald eagles in the country.If it were dropped from the Endangered Species List, the bald eagle would still be a threatened species. That means the bird would continue to get the same protection. No hunting allowed, and no disturbing of nests. But bald eagles still face tough times. The destruction of their natural homes could be the next DDT causing eagle numbers to drop quickly.
Question 14: What was the main harmful effect of the pests killer DDT on bald eagles?
Question 15: What measure did the wild life biologist take to increase the number of bald eagles?
Question 16: According to the speaker, what is the possible danger facing bald eagles?
If the earth gets hotter in the new century, what will happen to animals and the plants which animals depend on for survival? The question offers another way of looking at the "Greenhouse Effect".People have talked about the general problem of "Global Warming" for some time. But they were usually worried about things like whether to buy a home on the coast. Biologists and other scientists turn their attention to plants and animals at an important meeting that took place last October. They were reviewed evidence that plants and animals are sensitive to climate. Since the Ice Age ended ten thousand years ago and warmer temperatures returned to the northern latitudes, many species have migrated north. If the predictions about the Greenhouse are correct, temperatures will rise by the same amount in the next one hundred years as they did in the past ten thousand. Will animals and plants be able to adapt that quickly to change in the environment? Many won't. Certain species will probably become very rare. Experts say plants under climate stress will be very open to disease and fire. Forest fires may become more common. That, in turn, man harm animals that depend on the trees for food will for shelter. Any preserves we set up to protect endangered species may become useless as the species are forced to migrate along with their natural homes. Change is a part of life, but rapid change, says scientist George Woodwell, is the enemy of life.
Question 17: What is the concern of ordinary people about the "Greenhouse Effect"?
Question 18: What has happened since the end of the ICE AGE?
Question 19: What will be a possible threat to plants in the future?
Question 20: According to the passage, what will probably happen to the endangered species?
