Part A
Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the US had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to the moon in a dramatic show of technological muscle during the cold war.
Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone.
Today Mars looms as humanity's next great terra incognita. And with doubtful prospects for a short- term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is-clear that imperatives other than profits or nationalism will have to compel human beings to leave their tracks on the planet's reddish surface. Could it be that science. which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those experiments pro- vide insights profound enough to justify the expense of sending people across interplanetary space?
With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about the range of conditions under which a planet can generate the complex chemistry that leads to life, If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of life in the universe.
According to the passage, the chief purpose of explorers in going to unknown places in the past was ______.

A. to display their country's military might
B. to accomplish some significant science
C. to find new areas for colonization
D. to pursue commercial and state interests

Part B
Directions: Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2.
The distinctive architectural feature of the typical Broadway theater is the juxtaposition of two almost independent buildings facing and opening into one another through a proscenium arch. The audience sits in the auditorium structure and watches the actors perform. in the stage house. 61) This separation is more than an aesthetic impression, because the building codes require that a physical barrier protect the audience from a fire starting on the stage. A fireproof wall, rather than a more partition separates the structures, and 62) this separation is completed by a fireproof curtain that is rigged to fall automatically and close the proscenium opening in case of fire. Automatic fire doors similarly close all other openings between the two structures. The codes keep such openings to a minimum.
This separation came about in the 19th century in the United States as a result of theater fires. 63) It has produced a fundamental structural change from previous centuries without making much corresponding change in the appearance of the building. Most theaters of the 16th to 18th centuries were remodeled from banquet halls, tennis courts, and other rectangular halls and remained essentially a single structure with a thin partition for the proscenium wall.
So far as the audience is concerned, a theater is primarily a place for entertainment. 64) Its great attraction is the opportunity it affords for vicarious experience. The audience approaches the theater with the expectation of some form. of glamour, excitement, or emotional vividness. The architect and the decorator try to sustain and increase this excitement and anticipation as the spectator moves through the theater. 65) One of the familiar architectural devices for this effect is spaciousness of lobby, foyer, and auditorium. Color and ornamentation are other devices for the same purpose, as seen in almost all theaters built before the 20th century.

At this point we raise the troublesome methodological question, "What is a fact?" While the word looks deceptively simple, it is not easy to distinguish a fact from a widely shared illusion. Suppose we define a fact as a descriptive Statement upon which all qualified observers are in agreement. By this definition, medieval ghosts were a fact, since all medieval observers agreed that ghosts were real. There is, therefore, no way to be sure that a fact is an accurate description and not a mistaken impression. Research would be easier if facts were dependable, unshakable certainties. Since they are not, the best we can do is to recognize that a fact is a descriptive statement of reality which scientists, after careful examination and cross-checking, agree in believing to be accurate.
Since science is based on verifiable evidence, science can deal only with questions about which verifiable evidence can be found. Questions like "Is there a God?" "What is the purpose and destiny of man?" or "What makes a thing beautiful?" are not scientific questions because they can not be treated factually. Such questions may be terribly important, but the scientific method has not tools for handling them. Scientists can study human beliefs about God, or man's destiny, or beauty, or anything else, and they may study the personal and social consequences of such beliefs; but these are studies of human behavior, with no attempt to settle the truth or error of the beliefs themselves.
Science then does not have answers for everything, and many important questions are not scientific questions. The scientific method is our most reliable source of factual knowledge about human behavior. and the natural universe, but science with its dependence upon verifiable factual evidence cannot answer questions about value, or esthetics, or purpose and ultimate meaning, or supernatural phenomena. Answers to such questions must be sought in philosophy, metaphysics, or religion.
Each scientific conclusion represents the most reasonable interpretation of all the available evidence—but new evidence may appear tomorrow. Therefore science has no absolute truths. An absolute truth is one which will hold true for all times, places, or circumstances. All scientific truth is tentative, subject to revision in the light of new evidence. Some scientific conclusions (e.g., that the earth is a spheroid; or that innate drives are culturally conditioned) are based upon such a large and consistent body of evidence that scientists doubt that they will ever be overturned by new evidence. Yet the scientific method requires that all conclusions be open to reexamination whenever new evidence is found to challenge them.
The central idea of the passage is

A. scientific knowledge is based on verifiable evidence.
B. science does not have answers for verifiable evidence.
C. science has no absolute truths.
D. the scientific method requires that all conclusions be open to reexamination whenever new evidence is found to challenge them.
