Passage 1

　　Opinion polls are now beginning to show that, whoever is to blame and whatever happens from now on, high unemployment is probably here to say. This means we shall have to find ways of sharing the available employment more widely.

　　But we need to go further. We must ask some fundamental questions about the future work. Should we continue to treat employment as the norm? Should we not rather encourage many ways for self-respecting people to work? Should we not create conditions in which many of us can work for ourselves, rather than for an employer? Should we not aim to revive the household and the neighborhood, as well as the factory and the office, as centers of production and work?

　　The industrial age has been the only period of human history in which most people's work has taken the form of jobs. The industrial age may now becoming to an end, and some of the changes in work patterns which it brought may have to be reverseD.This seems a daunting thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom.

　　Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people's homes. Later, as transport improved, first by rail and then by road, people commuted longer distances to their places of employment until, eventually, many people's work lost all connection with their home lives and the places in which they live.

　　Meanwhile, employment put women at a disadvantage. In preindustrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and families to his wife. Tax and benefit regulations still assume this norm today, and restrict more flexible sharing of work roles between the sexes.

　　It was not only women whose work status suffereD.As employment became the dominant form of work, young people and old people were exclude—a problem now, as more teenagers become frustrated at school and more retired people want to live active lives.

　　All this may now have to change.

　　The time has certainly come to switch some effort and resources away from the idealist goal creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.

Passage 2

　　University Physics is intended for students of science and engineering. Primary emphasis is on physical principles and problem-solving; historical background and specialized practical applications have been given a place of secondary importance. Many worked-out examples and an extensive collection of problems are included with each chapter.

　　In this new edition, the basic philosophy and outline and the balance between depth of treatment and breadth of subject-matter coverage are unchanged from previous editions. We have tried to preserve those features that users of previous editions have found desirable, while incorporating a number of changes that should enhance the book's usefulness.

　　The textbook is adaptable to a wide variety of course outlines. The entire textbook can be used for an intensive course two or three semesters in length. For a less intensive course, many instructors will want to omit certain chapters or sections to tailor the book to their individual needs. The arrangement of this edition facilitates this kind of flexibility.

　　Conversely, however, many topics that were regarded a few years ago as of peripheral (外圍的)importance and were omitted from introductory courses have now come to the fore again in the life sciences, earth and space sciences, and environmental problems. An instructor who wishes to stress these kinds of applications will find this textbook a useful source for discussion of the appropriate principles.

　　In any case, it should be emphasized that instructors should not feel constrained (受約束的)to work straight through the book from cover to cover. Many chapters are, of course, inherently sequential in nature, but within this general limitation instructors should be encouraged to select among the contents those chapters that fit their needs, omitting material that is not relevant to the objectives of a a particular course.

6. This textbook lays stress on .
A.the exposition of physical principles
B.the principles of physics and their application
C.the development of physics
D.the application of physics in different fields

7. Compared with the old one, this new edition .
A.has been made more applicable
B.is easier to learn
C.covers a wider range of subject-matter
D.has improved the balance between theory and practice

8. One of the features of this textbook is that .
A.some contents are dealt with in terms of philosophy
B.it has an outline for each chapter
C.it introduces the physical principles in great length
D.it can be used for different course arrangements

9. The underlined words “conversely, however” (ParA.4) indicate that .
A.many topics can be emphasized though they were not covered in the old edition
B.many topics can be emphasized though they were usually omitted by instructors
C.many topics have been added to the new edition as they were not covered in the old one
D.many topics have been added to the new edition though they can be omitted by the instructors

10. To meet the needs of a particular course, the teacher of this book can omit some of the contents provided that .
A.his selection is based on the request of his students
B.he does not omit any chapter completely
C.his students are particularly intelligent
D.he keeps an eye on the internal relations between the chapters

Passage 3

　　Hamletfish are cautious lovers. Each evening at twilight, many times an evening in fact, a pair of them will leave the safety of their Caribbean reef and rush a few yards off the seafloor. Positioning themselves side-to-side, head-to-tail they hurriedly release their eggs and sperm. Then they turn sharply for home, leaves their gametes to mix in silence.

　　Ichthyologist Phillip Lobel of the Woods Hole Oceanographic Institution has found that hamlet fish and many other fish emit “cries of ecstasy" at the appropriate moment.

　　Biologists have long known that a few fish make sounds. The toadfish, for example, is named for its low call, which can be heard even above water. Underwater, however, human ears don't work well. As a result researchers didn't notice how common fish calls were until Lobel started diving with a video camera and an underwater microphone like the kind the Navy uses to listen for submarines.

　　Lobel has learned that the fish playing the role of the male-hamletifish switches roles from one tryst to the next-emits a series of short, low sounds. The female responds with a downward, sweeping sound like a slide whistle. The purpose to these calls, says Lobel, is probably to synchronize spawning, so that sperm and egg have a fighting chance of actually meeting in the water.

　　Then, at the moment of spawning, the female flutters her pectoral fins, contracts her abdominal muscles to squeeze out the eggs, and lets out a soft cry, which in part may simply be the sound of her swim bladder vibrating from all that muscle contraction. “The sound is not a scream, it's only as loud as conversation," says Lobel.

　　Lobel has since recorded sounds from about two dozen other fish species. He thinks fish calls, like some birdcalls, may be a means by which fish recognize suitable mates, and that fish of the same species may even communicate in regional dialects. “Lots of people sit and watch their little fish in their aquarium," Lobel says, “Well, it's like looking at a birdcage behind sound-proof glass. These things are all making sounds."

11. The primary purpose of this passage is to .
A.refute a misconception that fish don't make sounds
B.prove a new discovery
C.explain the time when hamletfish make sounds
D.demonstrate the fact that fish are romantic as human beings

12. Which of the following is NOT true about fish calls according to this passage?
A.Fish calls are commonly regarded as rare.
B.Some of sounds produced by fish are not uttered from their mouths.
C.Fish calls may be a means by which fish found their mates.
D.No sounds can be heard from fish if a person stands on the ground.

13. Which of the following best explains “the appropriate moment" for fish to emit cries of ecstasy mentioned in the first paragraph?
A.When Phillip Lobel was under the water with a video camera and a microphone.
B.When one fish has a tryst with another.
C.When the sperm and egg of the fish have a chance to meet in the water.
D.When fish are spawning.

14. Which of the following is a correct inference from the passage?
A.Few biologists have the idea fish may produce sounds underwater.
B.A person underwater may clearly hear the call of another person's above water.
C.Lobel's original intention to do the experiment was to test whether hamletfish would produce mating calls.
D.A hamletfish may play the roles of both male and female at different times.

15. The author mentioned birdcalls in the last paragraph in order .
A.to demonstrate that birds can be classified into certain fish species
B.to illustrate that birds, just like fish, produce calls to find their mates
C.to prove birdcalls are more common than fishcallsD.to further explain that fish is a kind of animal that may also make sounds when necessary

Passage 4

　　With human footprints on the moon, radio telescopes listening for messages from alien creatures (who may or may not exist), technicians looking for celestial (天體的)and planetary sources of energy to support our civilization, orbiting telescopes' data hinting at planetary systems around other stars, and political groups trying to figure out how to save humanity from nuclear warfare that would damage life and elimate on a planet-wide scale, an astronomy book published today enters a world different from the one that greeted books a generation ago. Astronomy has broadened to involve our basic circumstances and our mysterious future in the universe. With eclipese and space missions broadcast live, and with NASA(［美國］國家航空和宇宙航行局)，Europe, and the USSR (蘇聯(lián))planning and building permanent space stations, astronomy offers adventure for all people, an outward exploratory thrust that may one day be seen as an alternative to mindless consumerism, ideological bickering (爭吵)，and wars to control dwinding resources on a closed, finite Earth.

　　Today's astronomy students not only seek an up-to-date summary of astronomical facts: they ask, as people have asked for ages, about our basic relations to the rest of the universe. They may study astronomy partly to seek points of contact between science and other human endeavors: philosophy, history, politics, environmental action, even the arts and religion.

　　Science fiction writers and special effect artists on recent films help today's students realize that unseen worlds of space are real places—not abstract concepts. Today's students are citizens of a more real, more vast cosmos than conceptualized by students of a decade ago.

　　In designing this edition, the Wadsworh editors and I have tried to respond to these developments. Rather than jumping at the start into murky waters of cosmology (宇宙論)，I have begun with the viewpoint of ancient people on Earth and worked outward across the universe. This method of organization automatically (if loosely) reflects the order of humanity's discoveries about astronomy and provides a unifying theme of increasing distance and scale.

16. This passage is most probably taken from .
A.an article of popular science
B.the introduction of a book of astronomy
C.a lecture given by the author to astronomy students
D.the preface of a piece of science fiction

17. The author's purpose in presenting the first paragraph is .
A.to explain the background and new features of today's astronomy
B.to discuss in detail the most recent achievements in space research
C.to introduce some newly established space stations
D.to illustrate that the world today is different in many aspects from that of a generations ago

18. The author thinks that the growing interest in space exploration among people on Earth will probably lead to .
A.all people having chances of travelling in space
B.the realization of permanent settlement on other planets
C.more disturbance not only on Earth but also in outer space
D.orders, harmony and peace on our planet Earth

19. The author believes that today's astronomy students .
A.are much brighter than students of a generation ago
B.no longer care about astronomical facts
C.are better-informed about the unseen worlds of space
D.may learn more about man and his research in various fields through the study of astronomy

20. In the last paragraph, the underlined expression “these developments” refers to all of the following EXCEPT .
A.the development of science fiction and special effects of films
B.the new concepts about the universe acquired by today's astronomy students
C.the world-wide involvement in space exploration
D.humanity's new achievements in the field of astronomy
