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(shuō)明文，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。 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 s most polluted city. 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. 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.Delhi has been the centre of a succession of mighty empires and powerful kingdoms in India. Numerous ruins scattered throughout the territory offer a constant reminder of the area39。 【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，是一篇科研類閱讀，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。 （4）考查主旨大意。由此推斷，消極會(huì)消耗我們身體的能量，降低對(duì)疾病的抵抗力。re happy, but to slow down dramatically when we39。 （3）考查推理判斷。根據(jù)第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關(guān)注生活中積極的事物，是為了增強(qiáng)他們的免疫功能。選C。因此，當(dāng)我們的身體需要額外的能量時(shí)，（我們的身體）會(huì)去找免疫系統(tǒng)。 （1）考查推理判斷。十年前作者與生物學(xué)家羅伯特D.Age, health and happinessC.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage? A.Our ancestors evolved their immune systems in fighting against fierce animals.C. study? A.D.immune function and healthB.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. A.organs will speed up metabolic processes to answer itC.re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, being more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.（1）According to Robert Trivers, when our body needs extra energy, ______. A. As a result, our immune system evolved to run in maximum amounts when we39。t need to waste energy making immune cells to fight off tomorrow39。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you39。 Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive em
