　　1. 短阅读(精讲精炼Mock 4 section2)　　Biologist know that some marine algae can create clouds by producing the gas dimethylsulphide (DMS), which reacts with oxygen in air above the sea to form solid particles. These particles provide a surface on which water vapor can condense to form clouds. Lovelock contends that this process is part of global climatic-control system. According to Lovelock, Earth acts like a super organism, with all its biological and physical systems cooperating to keep it healthy. He hypothesized that warmer conditions increase algal activity and DMS output, seeding more clouds, which cool the planet by blocking out the Sun. Then, as the climate cools, algal activity and DMS level decrease and the cycle continues. In response to biologists who question how organisms presumably working for their own selfish ends could have evolved to behave in a way that benefits not only the planet but the organisms as well, cooling benefits the algae, which remain at the ocean surface, because it allows the cooled upper layers of the ocean to sink, and then the circulating water carries nutrients upward from the depths below. Algae may also benefit from nitrogen raining down from clouds they have helped to form.　　9. According to the passage, which of the following occurs as a result of cooling in the　　upper layers of the ocean?　　A. The concentration of oxygen in the air above the ocean’s surface decreases.　　B. The concentration of DMS in the air above the ocean’s surface increases.　　C. The nutrient supply at the surface of the ocean is replenished.　　D. Cloud formation increases over the ocean.　　E. Marine algae make more efficient use of nutrients.　　10. Which of the following is most similar to the role played by marine algae in the　　global climate control system proposed by Lovelock?　　A. A fan that continually replaces stale air in a room with fresh air from outside.　　B. A thermostat that automatically controls an air-conditioning system.　　C. An insulating blanket that retains heat.　　D. A filter used to purify water.　　E. A dehumidifier that constantly removes moisture from the air in a room.　　11. The passage mentions the possible benefit to algae of nitrogen falling down in the　　rain most likely in order to　　A. provide support for Lovelock’s response to an objection mentioned in the passage　　B. suggest that the climatic effects of DMS production have been underestimated　　C. acknowledge that Lovelock’s hypothesis is based in part on speculation　　D. demonstrate that DMS production alters the planet in more than one way　　E. assert that algae are the sole beneficiaries of DMS production　　2. 长阅读(直通车Part IV: Long passages passage 4)　　“Blues is for singing,” writes folk musicologist Paul Oliver, and “is not a form of folk song　　that stands up particularly well when written down.” A poet who wants to write blues can attempt　　to avoid this problem by poeticizing the form—but literary blues tend to read like bad poetry rather than like refined folk song. For Oliver, the true spirit of the blues inevitably eludes the self-conscious imitator. However, Langston Hughes, the first writer to grapple with these difficulties of blue poetry, in fact succeeded in producing poems that capture the quality of genuine, performed blues while remaining effective as poems. In inventing blues poetry, Hughes solved two problems: first, how to write blues lyrics in such a way that they work on the printed page, and second, how to exploit the blues form poetically without losing all sense of authenticity.　　There are many styles of blues, but the distinction of importance to Hughes is between the genres referred to as “folk blues” and “classic blues.” Folk blues and classic blues are distinguished from one another by differences in performers (local talents versus touring professionals), patronage (local community versus mass audience), creation (improvised versus composed), and transmission (oralversus written). It has been a commonplace among critics that Hughes adopted the classic blues as the primary model for his blues poetry, and that he writes his best blues poetry when he tries least to imitate the folk blues. In this view, Hughes’ attempts to imitate the folk blues are too self-conscious, too determined to romanticize the African American experience, too intent on reproducing what he takes to be the quaint humor and naïve simplicity of the folk blues to be successful.　　But a more realistic view is that by conveying his perceptions as a folk artist ought to—through an accumulation of details over the span of his blues oeuvre, rather than by overloading each poem with quaintness and naivety–Hughes made his most important contributions to the genre. His blues poems are in fact closer stylistically to the folk blues on which he modeled them than to the cultivated classic blues. Arnold Rampersad has observed that virtually all of the poems in the 1927 collection in which Hughes essentially originated blues poetry fall deliberatively within the “range of utterance” of common folk. This surely applies to “Young Gal’s Blues,” in which Hughes avoids the conventionally “poetic” language and images that the subjects of death and love sometimes elicit in his ordinary lyric poetry. To see what Hughes’ blues poetry might have been like if he had truly adopted the classic blues as his model, one need only look to “Golden Brown Blues,” a song lyric Hughes wrote for composer W.C. Handy. Its images, allusions, and diction are conspicuously remote from the common “range of utterance.”　　1. The primary purpose of the passage is to　　A. describe the influence of folk and classic blues on blues poetry　　B. analyze the effect of African American culture on blues poetry　　C. demonstrate that the language used in Hughes’ blues poetry is colloquial　　D. defend Hughes’ blues poetry against criticism that it is derivative　　E. refute an accepted view of Hughes’ blues poetry style　　2. The author of the passage uses the highlighted quotation primarily to　　A. indicate how blues poetry should be performed　　B. highlight the difficulties faced by writers of blues poetry　　C. support the idea that blues poetry is a genre doomed to fail　　D. illustrate the obstacles that blues poetry is unable to overcome　　E. suggest that written forms of blues are less authentic than sung blues　　3. It can be inferred from the passage that, as compared with the language of “Golden Brown Blues,”　　the language of “Young Gal’s Blues” is　　A. more colloquial　　B. more melodious　　C. marked by more allusions　　D. characterized by more conventional imagery　　E. more typical of classic blues song lyrics　　4. According to the passage, Hughes’ blues poetry and classic blues are similar in which of the　　following ways?　　A. Both are improvised　　B. Both are written down　　C. Both are intended for the same audience　　D. Neither uses colloquial language　　E. Neither is professionally performed　　3. 逻辑单题(直通车)　　Benovians set their clocks back an hour for the winter. The result is that, during winter’s short days, it is light when most commuters drive to work, but dark when they drive back home. Darkness contributes to accidents. Changing the clocks, however, does not actually increase the amount of driving done in the dark, so it is unlikely to have any effect on Benovia’s automobile accident rate.　　11. Which of the following is an assumption on which the argument relies?　　A. The average number of hours that Benovians drive when it is dark is greater for days during the　　winter than for days during other times of the year.　　B. In Benovia, hazards to safe driving that are made worse by darkness are as likely to occur in the　　morning as in the evening.　　C. The majority of cars on Benovia’s roads during a given day are those of people commuting to or　　from work.　　D. The majority of automobile accidents in Benovia take place when it is dark.　　E. Driving conditions are no worse in Benovia in the winter than during the rest of the year.
