As far as most scientists can tell, the green skies around powerful thunderstorms are usually a bination of red sunsets and water droplets.s ing from everywhere. Meanwhile, around sunset sunlight travels through so much atmosphere that just about all the blue is bounced away from the horizon, leaving all those reds and oranges behind. The sunset might look exclusively （獨(dú)有的）red and orange, but there39。s where water es in. Still, none of the conditions that can turn skies green are unique to the clouds that produce tornadoes. Sometimes they just lead to lots of rain, and maybe some hail. So if you see huge storm clouds rolling in and a green tint （色調(diào)）in the sky, it doesn39。s about to be a tornado, but it does mean you should probably head indoors.（1）What can be the best title for the text?

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. 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. Fireworks and firecrackers to celebrate the Hindu festival of Diwali then arrives, leaving Delhi the world39。The city39。 雖然政府發(fā)誓解決污染問題，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。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。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)以百萬計(jì)的防污口罩。由此可判斷出政府幾乎沒有保護(hù)其公民免受嚴(yán)重污染。 （2）考查推理判斷。學(xué)校、大學(xué)、醫(yī)院和市場(chǎng)分發(fā)了數(shù)百萬個(gè)防污染口罩。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。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.”本句是說新德里每年都籠罩在污染中。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。故選A。本文敘述了隨著城市的發(fā)展和越來越多的人口流動(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。故選B。8．閱讀短文，從每題所給的A、B、C和D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 Moving smoothly and silently through Alibaba Group Holding Ltd39。 The robots are part of a set of hightech tools that Alibaba says strongly cuts the hotel39。 Formally opened to the public last month, the 290room FlyZoo is an incubator for technology Alibaba wants to sell to the hotel industry in the future and an opportunity to showcase its prowess in artificial intelligence.
