　　A useful definition of an air pollutantis a compound added directly or indirectly by humans to the atmospherein suchquantities as to affect humans, animals, vegetation, or material adversely ***有害地.. Air pollution requires avery flexibledefinition that permits continuous change. When the first air pollution lawswere established inEngland in the fourteenth century, air pollutants werelimited to compounds that could be seen or smelled—a farcry ***懸殊的差別. from the extensive list of harmful substances known today. Astechnology has developed andknowledge of the health aspects of variouschemicals has increased, the list of air pollutants has lengthened. Inthefuture, even water vapor ***水蒸氣. might be consideredan air pollutant under certain conditions.

　　Many of the more important airpollutants, such as sulfur oxides, carbon monoxide, and nitrogen oxides,arefound in nature. As the Earth developed, the concentrations *** 濃度. of these pollutants were altered byvariouschemical reactions; they became components in biogeochemical ***生物地球化學的. cycles. These serve as an airpurification scheme by allowing thecompounds to move from the air to the water or soil. On a global basis,nature'soutput of these compounds dwarfs that resulting from human activities. However,human productionusually occurs in a localized area, such as a city.

　　In this localized region, human outputmay be dominant and may temporarily overload the natural purificationscheme ofthe cycles. The result is an increased concentration of noxious *** 有害的. chemicals in the air. Theconcentrations atwhich the adverse effects appear will be greater than the concentrations thatthe pollutants wouldhave in the absence of human activities. The actualconcentration need not be large for a substance to be apollutant; in fact thenumerical value tells us little until we know how much of an increase thisrepresents over the concentration that would occur naturally in the area. Forexample, sulfur dioxide has detectable health effects at0.08 parts per million***ppm., which is about 400 times its natural level.Carbon monoxide, however, has a naturallevel of 0.1 ppm and is not usually apollutant until its level reaches about 15 ppm.

　　61、It can be inferred from thefirst paragraph that _________

　　A.water vapor is an air pollutant in localized areas

　　B.the definition of air pollution will continue to change

　　C.a substance becomes an air pollutant only in cities

　　D.most air pollutants today can be seen or smelled

　　62、In what way can naturalpollutants play an important role in controlling air pollution?

　　A.They function as part of a purification process.

　　B.They are dwarfed by the pollutants produced by human activities.

　　C.They are less harmful to living beings than are other pollutants.

　　D.They have existed since the Earth developed.

　　63、According to the passage,the numerical value Of the concentration level of a substance is only useful if

　　A.the other substances in the area are known

　　B.it is a localized area

　　C.it can be calculated quickly

　　D.the naturally occurring level is also known

　　64、Which of the following isbest supported by the passage?

　　A.To effectively control pollution, local government should regularlyrevise the air pollution laws.

　　B.One of the most important steps in preserving natural lands is tobetter enforce air pollution laws.

　　C.Scientists should be consulted in order to establish uniform limitsfor all air pollutants.

　　D.Human activities have great impact on air pollution.

　　65、The passage mainlydiscusses _________

　　A.the economic impact on air pollution

　　B.how much damage air pollutants can cause

　　C.what constitutes an air pollutant

　　D.the quantity of compounds added to the atmosphere

　　四級英語仔細閱讀模擬題***二***

　　There are people in Italy who can’t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn or even frown when somebody mentions baseball. 『Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens.』① They tell you it’s a game better suited to the 19th century, slow, quiet, gentlemanly. These are the same people you may be one of them who love football because there’s the sport that glorifies “the hit”.By contrast, baseball seems abstract, cool, silent, still.

　　On TV the game is fractured into a dozen perspectives, replays, close?ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won’t do it for you.

　　Take, for example, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. 『But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or bring the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman’s position.』② Suppose the pitch is a ball. “Nothing happened,” you say. “I could have had my eyes closed.”

　　The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood. If football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.

　　1. The passage is mainly concerned with ______.

　　A. the different tastes of people for sports

　　B. the different characteristics of sports

　　C. the attraction of football

　　D. the attraction of baseball

　　2. Those who don’t like baseball may complain that ______.

　　A. it is only to the taste of the old

　　B. it involves fewer players than football

　　C. it is not exciting enough

　　D. it is pretentious and looks funny

　　3. The author admits that ______.

　　A. baseball is too peaceful for the young

　　B. baseball may seem boring when watched on TV

　　C. football is more attracting than baseball

　　D. baseball is more interesting than football

　　4. By stating “I could have had my eyes closed. ” the author means ***4th paragraph last sentence***:

　　A. The third baseman would rather sleep than play the game.

　　B. Even if the third baseman closed his eyes a moment ago, it could make no different to the result.

　　C. The third baseman is so good at baseball that he could finish the game with eyes closed all the time and do his work well.

　　D. The consequent was too bad he could not bear to see it.

　　5. We can safely conclude that the author ______.

　　A. likes football B. hates football

　　C. hates baseball D. likes baseball

　　四級英語仔細閱讀模擬題答案

　　1. D 主旨題。文章第一段簡述了人們對壘球所持的偏見——認為它毫無活力、從容和緩，不像橄欖球那樣***禁止***迭起、令人激動。文章的第二、三、四、五段探討了壘球的根本特徵及欣賞角度，文章的最後一句話用一個比喻概括了壘球的魅力：“如果橄欖球是一曲交響樂的話，那麼，壘球中所表現出來的運動恰似一曲優美的室內樂。”可見，本文主要探討的是壘球的特點及其欣賞。

　　2. C 細節題。文章第一段指出：許多人不喜歡壘球，一提起壘球這些人就打哈欠甚至皺眉頭。對他們來說，看壘球意味著眼巴巴地觀望著身著運動裝***outfit***的人呆立在球場上，東瞧瞧西望望，很少有什麼***激動人心的***事發生——沒意思透了。他們認為這樣的運動更適合上個世紀的人的口味，不像橄欖球那樣充滿活力。

　　3. B 推斷題。第三段指出，在電視上，壘球運動被切換成不同角度的畫面，而且不斷地使用重放、特寫等電視製作技術，這破壞了該運動的整體運動感，使觀眾無法將自己投入***project***到運動中去，以體會到這種寓動於靜的運動之美。電視做不到這一點***The TV won’t do it for you***，因此，電視上的壘球比賽看上去***seems***孤孤單單、冷冷清清、沉沉靜靜、慢慢騰騰。C、D不對，作者僅指出了不同運動有不同運動的特徵，並未說哪種運動優於哪種。

　　4. B 推斷題。第四段整個都在描述壘球場上的一個場景：拿三壘的運動員假設對方全投出好球，作好了一切準備，但是對方投出的並不是好球。所以在那時候他的準備做不做都不會影響比賽結果。他說本來可以閉上眼睛，意思就是B項所寫的。

　　5. D 推斷題。在本文中，作者主要探討了壘球的特徵及欣賞，作者著重指出的是：只有根據壘球的特徵來欣賞它，才能體會到它的魅力。在他看來，觀察到壘球比賽中運動員的各種動作、壘球位之間的關係等是欣賞它的關鍵***第三段第二句***。只有從整體來把握它，才能看到每一個小的動作、每一個眼神乃至於“靜止”的意義，也只有這樣，才能全身心地投入比賽中，欣賞到它的魅力。可見，作者對壘球有很深的理解而且非常喜愛壘球。
