Questions 21 to 25 are bad 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, the 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 t 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 without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could u it to hunt down sites that are easy to burgle (闯入…...行窃).
考研政治复习But Farmer is very concerned about the need to alert the public to poor curity and, so far,
events have proved him right. SATAN has done more to alert people to the risks than cau new disorder. So is the Net becoming more cure? Far from it. In the early days, when you visited a Web site your browr 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. The 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 ek out and classify information. All the make wonderful tools for antisocial people who want to invade weak sites and cau 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 becau hackers are fundamentally honest. Or that there currently isn’t much to steal. Or becau 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 curity t
o become the number one issue, when the most influential inhabitants of the Net are lling rvices they want to be paid for.

Questions 26 to 30 are bad 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 teaching. Students must be incorporated, made, so far as possible, an integral part of the learning process. The notion that learning should have in it an element of inspired play would em to the greater part of the academic establishment merely silly, but that is nonetheless the ca. Of Ezekiel Cheever, the most famous schoolmaster of the Massachutts 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 clo attention to this form of education. There is, I think, much truth in Patricia Nelson Limerick’s obrvation 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 possd by the urge to speak, and to speak while others remain silent. Bu
t to do this regularly, one hour and 15 minutes at for one person to drag on while others sit in silence?... I do not believe that this is what 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 cour, some years. Edward Shils, professor of sociology, recalls the professors he encountered at the University of Pennsylvania in his youth. They emed “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 rved for years, to judge by the The teachers began on time, ended on time, and left the room without saying a word more to their stud
ents, very ldom being detained The class were not large, yet there was no discussion. No questions were raid in class, and there were no office hours.”

Questions 31 to 35 are bad on the following passage.
Take the ca of public education alone. The principal difficulty faced by the schools has been the tremendous increa in the number of pupils. This has been caud 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 the 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 prent trend toward a shorter day and a shorter week will be maintained. We have developed and shall continue to have a new leisure cla
ss. 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 the increas in the cost of public education can be borne by the local communities. They cannot care for the prent 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 prerve the prent generation through Federal relief of the destitute (贫民). Only a people determined to ruin the next generation will refu 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.（B）
32. What is the reason for the increa 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.tenniscourt

A) should allocate Federal funds for public education

D) should first of all solve the problem of unemployment（A）
35. Why does the author say “Only a people determined to ruin the next generation will refu such Federal funds as public education may require” (Lines 10-11, Para. 3)?什么是evd

C) People all over the country should make contributions to education in the interest of the next generation.
D) Educated people are determined to u part of the Federal funds to help the poor.
Questions 36 to 40 are bad on the following passage.
A new high-performance contact lens under development at the department for applied physics 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 ud in astronomical telescopes to spot newly emerging stars and far distant galaxies. Connected to a wave-front nsor that tracks and measures the cour of a lar 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 preci data from the two instruments—which, Bille hopes, will one day be found at the opticians (眼镜商) all over the world—rve as a basis for the production of completely individualized contact lens that correct and enhance the wearer’s vision.
By day, Bille’s contact lens 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 surpass that of conventional vision aids by almost half a diopter ( 屈光度). At night, the lens have an even greater potential. “Becau 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 e. In his experiments night vision was enhanced by an even greater factor: in mi-darkness, test subjects could e up to 15 times better than without the lens.
Bille’s lens are expected to reach the market in the year 2000, and one tentative plan is to u the Internet to transmit information on patients’ visual defects from the optician to the manufacturer, who will then produce and mail the contact lens within a couple of days. The physicist expects the lens to cost about a dollar a pair, about the same as conventional one-day disposable lens.
36. The new contact lens is meant for ________.
A) astronomical obrvations
B) the night blind
C) tho with vision defects
D) optical experiments（C）
37. What do the two instruments mentioned in the cond paragraph (Line 5) refer to?
A) The astronomical telescope and the wave-front nsor.
B) The aluminum mirror and the lar beam.
C) The active mirror and the contact lens.
D) The aluminum mirror and the wave-front nsor.（D）
38. Individualized contact lens (Line 7, Para. 2) are lens 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（B）
39. According to Bille, with the new lens 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
小猴子英文D) will be sharper by a much greater degree at night than in the daytime（D）
