Numerous ruins scattered throughout the territory offer a constant reminder of the area39。With the development of the city and more and more people moving, the city has expanded several times in size. That is why it is called New Delhi. New Delhi, a city with a population of over 20 million people, has its newest problem: never before has this city met with the worst air problem. Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets. s most polluted city. s air quality index, which measures a mix of dangerous pollutants, registered an average score of 494 Sunday. That is the highest 24hour average since Nov. 6, 2016, when it hit 497, according to data measured by the Central Pollution Control Board.（1）Which of the following is NOT true? is one of the most important festivals in India. government did little to protect its citizens against the serious pollution. a serious air pollution in New Delhi appears on a regular basis. index of the recent air pollution is not the worst in the history.（2）Who may not plain about the serious air pollution? parents whose children have to stay at home. pilots whose planes have been diverted or delayed. manufacturers who produce antipollution masks. officials who have to work out of their offices.（3）Which of the following phrases can replace the underlined word in paragraph 5? out. up. in. on.（4）The title of the passage should be . Caused by the Development of New Delhi Pollution Envelops New Delhi Masks Are in Great Need in New Delhi in the Neighboring States are to Blame for Burning Crop Stubble【答案】 （1）B（2）C（3）A（4）B 【解析】【分析】本文是一篇說明文，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。 （1）考查推理判斷。s most polluted city.” 新德里每年都會(huì)被污染吞沒，隨著天氣變冷，汽車和以煤為基礎(chǔ)的發(fā)電廠排放的污染物、建筑工地和道路上飄動(dòng)的灰塵，以及鄰國農(nóng)作物秸稈燃燒產(chǎn)生的煙霧，都會(huì)形成濃霧?？芍?，政府盡管發(fā)誓解決這種污染，但情況不僅沒有改變，反而更加嚴(yán)重，使得人們必須佩戴防毒口罩。故選B。根據(jù)第四段“Hundreds of flights were diverted, delayed and canceled over the weekend due to poor visibility, schools and offices were closed Monday and officials rushed to take emergency measures to try to reverse the eroding air quality. Millions of antipollution masks were distributed at schools, colleges, hospitals and markets.” 周末期間，由于能見度低，數(shù)百架航班被迫改道、延誤和取消，學(xué)校和辦公室周一關(guān)閉，官員們緊急采取措施，試圖扭轉(zhuǎn)不斷惡化的空氣質(zhì)量。由此可知，由于污染嚴(yán)重，學(xué)校、大學(xué)、醫(yī)院和市場分發(fā)了數(shù)百萬個(gè)防污染口罩。 （3）考查詞義猜測(cè)。因?yàn)樘鞖庾兝?，從汽車和以煤為基礎(chǔ)的發(fā)電廠“emitted”的污染物形成了厚厚的霧霾。由此可判斷“emitted”是排放的意思。 （4）考查主旨大意。雖然政府發(fā)誓解決污染問題，但周末的能見度低，數(shù)百架航班在周末改道、延誤和取消，學(xué)校和辦公室周一關(guān)閉，人們必須戴防污口罩，可知，新德里被嚴(yán)重的污染所籠罩。 【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷，詞義猜測(cè)和主旨大意三個(gè)題型的考查，是環(huán)保類閱讀，考生需要根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay fortable in a cooler room. Or, picture a car windshield that stores the sun39。According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing. s energy through a chemical reaction and releasing it later as heat. Such chemicallybased storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not able to make durable (耐用的) solidstate films. The new approach is the first based on a solidstate material, in this case a polymer, and the first based on inexpensive materials and widespread production technology.（1）What is the main purpose of Paragraph 1? show the main idea of the passage. practice reader
