It is a popular misconception that nuclear fusion 核聚变 power is free of radioactivity 放射性; in fact, the deuterium- tritium 氘和氚 reaction that nuclear scientists are currentlyexploring with such zeal produces both alpha particlesand neutrons. (The neutrons are used to produce tritium from a lithium blanket surrounding the reactor.) D 和 T 都会发出射线，阿尔法粒子和 中子， 中子来自于锂变成的 TAnother common misconception is that nuclear fusion power is a virtually unlimited source of energy because of the enormous quantity of deuterium in the sea.Actually, its limits are set by the amount of available lithium, which is about as plentiful as uranium 铀 in the Earth‘s crust. Research should certainly continue on controlled nuclear fusion, but no energy program should be premised on its existence until it has provenpractical. (122 words) 1. It can be inferred from the passage that theauthor believes which of the following about the current state of public awareness concerningnuclear fusion power? (A) The public has been deliberately misinformedabout the advantages and disadvantages ofnuclear fusion power. (B) The public is unaware of the principaladvantage of nuclear fusion over nuclearfission as an energy source. (C) The public‘s awareness of the scientificfacts concerning nuclear fusion power issomewhat distorted and incomplete. (D) The public is not interested in increasing itsawareness of the advantages anddisadvantages of nuclear fusion power. (E) The public is aware of the disadvantages ofnuclear fusion power but not of itsadvantages.

Roger Rosenblatt‘s book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken bymost previous studies. 【rather than 表明是用 literary，successfully 表明作者支持】As Rosenblatt notes, criticismof Black writing has often served as a pretext 借口 for expounding 阐述 on Black history. Addison Gayle‘s recent work, for example, judges the value of Black fiction by overtly 明显地，公开地 political standards, rating each work according to the notions of Black identity which it propounds 提出，建议.Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideological, and talking about novels
and stories primarily as instruments of ideology circumvents much of the fictional enterprise. Rosenblatt‘s literaryanalysis discloses affinities and connections among works of Black fiction which solely political studies have overlooked or ignored.Writing acceptable criticism of Black fiction, however, presupposes 假定以。。为条件 giving satisfactory answers to a number 。 ofquestions. First of all, is there a sufficient reason,other than the racial identity of the authors, to group together works by Black authors? Second, how does Black fiction make itself distinct from other modern fiction with which it is largely contemporaneous 同时代的，同时期 的?Rosenblatt shows that Black fiction constitutesa distinct body of writing that has an identifiable, coherent literary tradition. Looking at novels written by Blacks over the last eighty years, he discovers recurring 循环的 concerns and designs independent of chronology. These structures are thematic 主题的, and they spring, not surprisingly,from the central fact that the Black characters in these novels exist in a predominantly White culture, whether they try to conform to that culture or rebel against it. Black Fiction does leave some aesthetic questionsopen. Rosenblatt‘s thematic analysis permits considerable objectivity; he even explicitly states that it is not his intention to judge the merit of the various works—yet his reluctance seems misplaced, especially since an attempt to appraise 评价，鉴定 might have led to interesting results. Forinstance, some of the novels appear to be structurally diffuse 弥漫的. Is this a defect, or are the authors working out of, or trying to forge, a different kind of aesthetic? In addition, the style of some Black novels, like Jean Toomer‘s Cane, verges on 趋近，接近 expressionism or surrealism;does this technique provide a counterpoint to the prevalent theme that portrays the fate against which Black heroes are pitted, a theme usually conveyed by morenaturalistic modes of expression? In spite of such omissions 疏忽【提示上文描写了这个 critism 的缺点】, what Rosenblatt doesinclude in his discussion makes for an astute 机敏的 and worthwhile study. Black Fiction surveys a wide variety of novels, bringing to our attention in the process some fascinating and little-known works like James Weldon Johnson‘s Autobiography of an Ex-Colored Man. Its55 argument is tightly constructed, and its forthright, lucid style exemplifies levelheaded and penetrating criticism.

The author of the passage is primarily concerned with (A) evaluating the soundness of a work of criticism
(B) comparing various critical approaches to a subject (C) discussing the limitations of a particularkind of criticism (D) summarizing the major points made in awork of criticism【是讲了 RR 评论的优缺点，不是 major points】 (E) explaining the theoretical background of acertain kind of criticism

6. The author of the passage refers to JamesWeldon Johnson‘s Autobiography of an Ex-Colored Man most probably in order to (A) point out affinities between Rosenblatt‘smethod of thematic analysis and earliercriticism (B) clarify the point about expressionistic stylemade earlier in the passage (C) qualify the assessment of Rosenblatt‘s bookmade in the first paragraph of the passage (D) illustrate the affinities among Black novelsdisclosed by Rosenblatt‘s literary analysis (E) give a specific example of one of theaccomplishments of Rosenblatt‘s work
The transfer of heat and water vapor from the oceanto the air above it depends on a disequilibrium 不平衡 at theinterface of the water and the air. Within about amillimeter of the water, air temperature is close to that ofthe surface water, and the air is nearly saturated 饱和 withwater vapor. But the differences, however small, arecrucial, and the disequilibrium is maintained by air nearthe surface mixing with air higher up, which is typicallyappreciably 相当 地，可察觉地 cooler and lower in water-vapor content. The air is mixed by means of turbulence that dependson the wind for its energy. As wind speed increases, sodoes turbulence, and thus the rate of heat and moisturetransfer. Detailed understanding of this phenomenonawaits further study. (127 words)
