1、【题目】The discovery of the Antarctic not only proved one of the most interesting of all geographical adventures, but created what might be called “the heroic age of Antarctic exploration”. By their tremendous heroism, men such as Shakleton, Scott, and Amundsen caused a new continent to emerge from the shadows, and yet that heroic age, little more than a century old, is already passing. Modern science and inventions are revolutionizing the endurance, future journeys into these icy wastes will probably depend on motor vehicles equipped with caterpillar traction rather than on the dogsthat earlier discoverers found so invaluable and hardly comparable.
Few realize that this Antarctic continent is almost equal in size to South America, and enormous field of work awaits geographers and prospectors. The coasts of this continent remain to be accurately charted, and the maping of the whole of the interior presents a formidable task to the cartographers who undertake the work. Once their labors are completed, it will be possible to prospect the vast natural resources which scientists believe will furnish one of the largest treasure hoards of metals and minerals the world has yet known, and almost inexhaustible sources of copper,coal, uranium, and many other ores will become available to man. Such discoveries will usher in an era of practical exploitation of the Antarctic wastes.
The polar darkness which hides this continent for the six winter months will be defeated by huge batteries of light, and make possible the establishing of air-fields for the future inter-continental air services by making these areas as light as day. Present flying routes will be completely changed, for the Antarctic refueling bases will make flights from Australia to South America comparatively easy over the 5,000 miles journey.
The climate is not likely to offer an insuperable problem, for the explorer Admiral Byrd has shown that the climate is possible even for men completely untrained for expeditions into those frozen wastes. Some of his parties were men who had never seen snow before, and yet he records that they survived the rigors of the Antarctic climate comfortably, so that, provided that the appropriate installations are made, we may assume that human beings from all countries could live there safely. Byrd even affirms that it is probably the most healthy climate in the world, for the intense cold of thousands of years has sterilize this continent, and rendered it absolutely germfree, with the consequences that ordinary and extraordinary sickness and diseases from which man suffers in other zones with different climates are here utterly unknown. There exist no problems of conservation and preservation of food supplies, for the latter keep indefinitely without any signs of deterioration; it may even be that later generations will come to regard the Antarctic as the natural storehouse for the whole world.
Plans are already on foot to set up permanent bases on the shores of this continent, and what so few years ago was regarded as a “dead continent” now promises to be a most active center of human life and endeavor.
1.When did man begin to explore the Antarctic?
A.About 100years ago.
B.In this century.
C.At the beginning of the 19th century.
D.In 1798.
2.What must the explorers be, even though they have modern equipment and techniques?
A.Brave and tough
B.Stubborn and arrogant.
C.Well-liked and humorous.
D.Stout and smart.
3.The most healthy climate in the world is___.
A.in South America.
B.in the Arctic Region.
C.in the Antarctic Continent.
D.in the Atlantic Ocean.
4.What kind of metals and minerals can we find in the Antarctic?
A.Magnetite, coal and ores.
B.Copper, coal and uranium.
C.Silver, natural gas and uranium.
D.Aluminum, copper and natural gas.
5.What is planned for the continent?
A.Building dams along the coasts.
B.Setting up several summer resorts along the coasts.
C.Mapping the coast and whole territory.
D.Setting up permanent bases on the coasts.

1、【题目】Most of us are taught to pay attention to what is said—the words. Words do provide us with some information, but meanings are derived from so many other sources that it would hinder our effectiveness as a partner to a relationship to rely too heavily on words alone. Words are used to describe only a small part of the many ideas we associate with any given message. Sometimes we can gain insight into some of those associations if we listen for more than words. We don’t always say what we mean or mean what we say. Sometimes our words don’t mean anything except “ I’m letting off some steam. I don’t really want you to pay close attention to what I’m saying. Just pay attention to what I’m feeling.” Mostly we mean several things at once. A person wanting to purchase a house says to the current owner, “This step has to be fixed before I’ll buy.” The owner says, “ It’s been like that for years.” Actually, the step hasn’t been like that for years, but the unspoken message is: “ I don’t want to fix it. We put up with it. Why can’t you?” The search for a more expansive view of meaning can be developed of examining a message in terms of who said it, when it occurred, the related conditions or situation, and how it was said.
When a message occurs can also reveal associated meaning. Let us assume two couples do exactly the same amount of kissing and arguing. But one couple always kisses after an argument and the other couple always argues after a kiss. The ordering of the behaviors may mean a great deal more than the frequency of the behavior. A friend’s unusually docile behavior may only be understood by noting that it was preceded by situations that required an abnormal amount of assertiveness. Some responses may be directly linked to a developing pattern of responses and defy logic. For example, a person who says “No!” to a serials of charges like “You’re dumb,” “You’re lazy,” and “You’re dishonest,” may also say “No!” and try to justify his or her response if the next statement is “And you’re good looking.”
We would do well to listen for how messages are presented. The words, “If sure has been nice to have you over,” can be said with emphasis and excitement or ritualistically. The phrase can be said once or repeated several times. And the meanings we associate with the phrase will change accordingly. Sometimes if we say something infrequently it assumes more importance; sometimes the more we say something the less importance it assumes.
1.Effective communication is rendered possible between two conversing partners, if ___.
A.they use proper words to carry their ideas.
B.they both speak truly of their own feelings.
C.they try to understand each other’s ideas beyond words.
D.they are capable of associating meaning with their words.
2.“I’m letting off some steam” in paragraph 1 means___.
A.I’m just calling your attention.
B.I’m just kidding.
C.I’m just saying the opposite.
D.I’m just giving off some sound.
3.The house-owner’s example shows that he actually means___.
A.the step has been like that for years.
B.he doesn’t think it necessary to fix the step.
C.the condition of the step is only a minor fault.
D.the cost involved in the fixing should be shared.
4.Some responses and behaviors may appear very illogical, but are justifiable if___.
A.linked to an abnormal amount of assertiveness.
B.seen as one’s habitual pattern of behavior.
C.taken as part of an ordering sequence.
D.expressed to a series of charges.
5.The word “ritualistically” in the last paragraph equals something done___.
A.without true intention.
B.light-heartedly.
C.in a way of ceremony.
D.with less emphasis.
