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．The income gap really does harm to social order.B．Government agencies are working ha

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.
