【正文】 manpower.”根據(jù)最后一段中的“Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes”今后的工作將繼續(xù)側(cè)重于提高識(shí)別物體和成像形狀及體積的準(zhǔn)確性，故選B。 Shining iridescent color, which changes depending on the angle from which it39。 And in our research group we are of course interested in why this vivid metallic color is so widespread in nature. Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract mates.

Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動(dòng)物用來(lái)通過(guò)逃離捕食者而活得更久，排除A；根據(jù)第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現(xiàn)出強(qiáng)烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現(xiàn)很可能是由性別選擇所驅(qū)動(dòng)的。t a new one.”引人注目的顏色可以用來(lái)偽裝，這種想法并不新鮮，排除C，故選D。 （3）考查推理判斷。 （4）考查主旨大意。 Science【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了一項(xiàng)新的研究成果多看綠色植物和吃垃圾食品這兩者看似風(fēng)馬牛不相及，可研究結(jié)構(gòu)卻表明它們之間存在著一種奇妙的關(guān)系：多看綠色植物能幫助人們克制吃垃圾食品的欲望。 （2）考查詞義猜測(cè)。根據(jù)倒數(shù)第二段中的“…adds a new dimension(方面) to the previous research”為以前的研究增加了新的方面，可知，新的研究在某種程度上豐富了之前的研究成果。故選C。 Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem. 根據(jù)第三段“Air pollution in Indians capital surged to its worst levels in years, covering the city in a thick smog that has bee an annual publichealth emergency despite government vows to solve the problem.”印度首都的空氣污染飆升至多年來(lái)最嚴(yán)重的水平，籠罩著這座城市的濃霧已成為年度公共衛(wèi)生緊急事件，盡管政府誓言要解決這個(gè)問(wèn)題；第五段“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust ..., leaving Delhi the world39。由此可判斷出政府幾乎沒(méi)有保護(hù)其公民免受嚴(yán)重污染。學(xué)校、大學(xué)、醫(yī)院和市場(chǎng)分發(fā)了數(shù)百萬(wàn)個(gè)防污染口罩。根據(jù)第五段中的“New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states.”本句是說(shuō)新德里每年都籠罩在污染中。故選A。故選B。本文敘述了隨著城市的發(fā)展和越來(lái)越多的人口流動(dòng)，城市規(guī)模的擴(kuò)大，印度的新德里成為世界上污染最嚴(yán)重的城市。根據(jù)常識(shí)可知，汽車和用煤發(fā)電的發(fā)電廠會(huì)“排放或釋放”污染物的。所以生產(chǎn)防污染口罩的廠家要加大生產(chǎn) ，是不會(huì)抱怨的，故選C。 （2）考查推理判斷。慶祝印度排燈節(jié)的煙花爆竹隨后到達(dá)，使德里現(xiàn)在成為世界上污染最嚴(yán)重的城市；以及第四段中的“Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 在學(xué)校、學(xué)院、醫(yī)院和市場(chǎng)上分發(fā)了數(shù)以百萬(wàn)計(jì)的防污口罩。雖然政府發(fā)誓解決污染問(wèn)題，但由于污染嚴(yán)重，整個(gè)新德里處于危險(xiǎn)的污染中，人們必須戴防污口罩，冬天天氣寒冷污染物成霧霾，成為世界是污染最嚴(yán)重的城市。 The city39。New Delhi, is engulfed each year as the weather cools and a thick haze builds up from the pollutants emitted from cars and coalbased power plants, swirling dust from construction sites and roads and smoke from crop stubble burning in neighboring states.
