案例分析题In the following passage, there are 20 blanks representing the words that are missing from the context. You are to put back in each of the blanks the missing worD．The time for this section is 20 minutes.Many things about language are a mystery, and many will always remain so. But some things we do know.First, we know that all human beings have a language of some sort.(1) is no race of men anywhere on earth so backward that it has (2) language, no set of speech sounds by which the people communicate with one(3) . Furthermore, in historical times, there has never been a race of men (4) a language.Second, there is no such thing as a primitive language. There are many people (5) cultures are underdeveloped, who are, as we say, uncivilized, but the (6) they speak are not primitive. In all known languages we can see complexities (7) must have been tens of thousands of years in development.This has not (8) been well understood; indeed, the direct contrary has often been stateD．Popular ideas (9) the language of the American Indians will illustrate. Many people have supposed that the Indians (10) in a very primitive system of noises. Study has proved this (11) be nonsense. There are, or were, hundreds of American Indian languages, and all of them(12) out to be very complicated and very old．They are certainly (13) from the languages that most of us are familiar with, but they are (14) more primitive that English and Greek.A third thing we know about language (15) that all languages are perfectly adequate. That is, each one is a perfect (16) of expressing the culture of the people who speak the language.Finally, we (17) that language changes. It is natural and normal for language to change; the (18) languages which do not change are the dead ones. This is easy to (19) if we look backward in time. Change goes in all aspects of language. (20) features change as do speech sounds, and changes in vocabulary are sometimes very extensive and may occur very rapidly. Vocabulary is the least stable part of any language. （4）处应填写（）
案例分析题In this section you will find after each of the passages a number of questions or unfinished statements about the passage, each with 4 (A, B, C and D) choices to complete the statement. You must choose the one which you think fits best. The time for this section is 75 minutes.questions 1-5 are based on the following passage.Non-indigenous (non-native) species of plants and animals arrive by way of two general types of pathways. First, species having origins outside the United States may enter the country and become established either as free-living populations or under human cultivation-for example, in agriculture, horticulture, aquaculture, or as pets. Some cultivated species subsequently escape or are released and also become established as free-living populations. Second, species of either US or foreign origin and already within the United States may spread to new locales. Pathways of both types include intentional as well as unintentional species transfers. Rates of species movement driven by human transformations of natural environments as well as by human mobility-through commerce, tourism, and travel-greatly exceed natural rates by comparison. While geographic distributions of species naturally expand or contract over historical time intervals (tens to hundreds of years), species-ranges rarely expand thousands of miles or across physical barriers such as oceans or mountains.Habitat modification can create conditions favorable to the establishment of non-indigenous species. Soil disturbed in construction and agriculture is open for colonization by non-indigenous weeds, which in turn may provide habitats for the non-indigenous insects that evolved with them. Human-generated changes in fire frequency, grazing intensity, as well as soil stability and nutrient levels similarly facilitate the spread and establishment of non-indigenous plants. When human changes to natural environments span large geographical areas, they effectively create passages for species movement between previously isolated locales. The rapid spread of the Russian wheat aphid to fifteen states in just two years following its 1986 arrival has been attributed in part to the prevalence of alternative host plants that are available when wheat is not. Many of these are non- indigenous grasses recommended for planting on the forty million or more acres enrolled in the US Department of Agriculture Conservation Reserve Program.A number of factors perplex quantitative evaluation of the relative importance of various entry pathways. Time lags often occur between establishment of non-indigenous species and their detection, and tracing the pathway for a long-established species is difficult. Experts estimate that non-indigenous weeds are usually detected only after having been in the country for thirty years or having spread to at least ten thousand acres. In addition, federal port inspection, although a major source of information on non-indigenous species pathways, especially for agriculture pests, provides data only when such species enter via closely-examined routes. Finally, some comparisons between pathways defy quantitative analysis-for example, which is more "important": the entry path of one very harmful species or one by which many but less harmful species enter the country To determine the entry pathway for a non-native species is LEAST likely to depend on（）

案例分析题Questions 11-15 are based on the following passage.Edgar Snow was a reporter and a joumalist. He was a doer, a seeker of facts. His mature years were spent in communicating to people-he was an opener of minds, a bright pair of eyes on what went on about him. Fortunately, he went to many places, knew many people, saw many things; thus he communicated from depth and involvement. Suspicious of dogma, he stated in his autobiography. "What interested me was chiefly people, all kinds of people, and what they thought and said and how they lived-rather than officials, and what they said in their interviews and handouts about whatthey people’ thought and saiD．" In writing about people and the event which shaped or misshaped their lives, his point of view was essentially honest and searching- founded on his own inquiry and resting on a body of truth perceived with vision and with compassion. His valued friend and editor, Mary Heathcote, stated that to Edgar Snow, "true professionalism meant telling the truth as one saw it, with as many of the reasons for its existence as one could find out and as much empathy as possible for the people experiencing it..."That he is remembered mostly through Red Star Over China is understandable. The accounts in that book were of international importance and the experience for the author in getting those accounts was perhaps the most significant one in his life. Though it is typical of him what, after the acclaim the book received, he commented, "I simply wrote down that I was told by the extraordinary young men and women with whom it was my privilege to live at age thirty, and from whom I learned a great deal. " That "great deal" spread from the pages of Red Star to alter the thinking of countless people—including many citizens of China who were led by it to action that drastically affected their own lives and the course of their country’s future. An awesome realization of personal responsibility also came about at this point for the young journalist, one he was cognizant of the rest of his life—the discovery, as he heard of friends and students killed in a war they had been moved to join largely because of his reports, that his writing had taken on the nature of political action and that he, as a writer, had to be personally answerable for all he wrote.There were other texts which broke through ignorance and prejudice in similar ways: Far Eastern Front, Living China, Battle for Asia, People on Our Side, Journey To the Beginning, to name some of the eleven books he produced, as well as many pages of engaged reporting—of floods and famines, of wars declared and undeclared, of human dilemmas and indignities, of unsung heroes and unheralded sacrifices-a life’s study of the impact of people and events from many lands known at first hanD．Ed represents what is best in American joumalism—as did his compatriot Agnes Smedley and Jack Belden. They dedicated to action, to communication that would help lessen the need, help correct the injustices. A main objective of theirs, because they were there and they saw, because they were internationalists with concern for human welfare, values and dignity, was to contribute to an understanding of China and the crippling burdens she bore—in a world dominated by arrogance, greed, and ignorance. According to the article, the writings of Edgar Snow were based on（）
