【正文】 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。 【點評】本題考點涉及細(xì)節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。因此，本文的最佳標(biāo)題應(yīng)為“格陵蘭島曾經(jīng)更加綠色”。 （4）考查主旨大意?！案窳晏m西北部可能真的感覺很遙遠(yuǎn)，但冰蓋的變化將關(guān)系到世界上每個沿海城市的每個人。根據(jù)第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 故選B。根據(jù)第三段中的“This new information could help researchers better measure Greenland39。故選C。根據(jù)第一段中的“The mud, and remains of mon flies in it, record two interglacial periods（間冰期）in northwest Greenland.”在格陵蘭島西北部，泥漿和常見蒼蠅的殘骸記錄了兩次間冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”盡管研究人員很早就知道這兩個時期——全新世早期和最后一次間冰期——在北極經(jīng)歷了變暖，但混合的蠅類表明格陵蘭島甚至比之前認(rèn)為的還要熱?，F(xiàn)在研究人員認(rèn)為，格陵蘭北部的冰蓋經(jīng)歷了比之前認(rèn)為的更強(qiáng)烈的變暖。s scientists to find ancient lake deposits. are surprised at the landscape feature of Greenland today. measure the changing temperatures by directly examining mud. holds enough ice that might one day threaten life in coastal cities.（4）Which do you think is the best title of the passage?

During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica39。s ice sheet might respond to manmade global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world, said Yarrow Axford, an associate professor in the team. One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today, said Axford. This new information could help researchers better measure Greenland39。s past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of mon flies in it, record two interglacial periods(間冰期)in northwest Greenland.4．Directions: Choose the one that fits best according to the information given in the passage you have just read. 故選B。所以短文的最佳標(biāo)題為讓現(xiàn)代科技溫暖你的冬日。人們憑借科學(xué)技術(shù)發(fā)明了各式各樣的防寒方法。通讀全文可知，在科技并不發(fā)達(dá)的過去，人們可能會為如何在嚴(yán)寒天氣里更好地保暖而倍感困擾。故選C。先進(jìn)的技術(shù)、引擎環(huán)和設(shè)計為我們提供了解決老問題的新方法。根據(jù)第二段中的Fortunately, things don39。故選A。根據(jù)第四段中的 At the touch of a button, or through an app on our phones, the clothing generates heat from elements placed inside. 可知，只要按下按鈕，或者通過手機(jī)上 應(yīng)用程序，安裝在衣服內(nèi)部的電子元件就會產(chǎn)生熱量。故選D。所以通過 keep warm可知，外出時要想暖和一些，就要多穿衣服。根據(jù)第一段中的In my memory, winters always used to be really unpleasant. You had to bundle up just to keep warm when you went outside. 可知，在我的記憶中，冬天總是很不令人愉快。比如，用智能電子設(shè)備調(diào)節(jié)屋內(nèi)和衣物的溫度；使用無線科技制造會自動發(fā)熱的服飾?，F(xiàn)如今，每到嚴(yán)冬時節(jié)，雖然溫度驟降、天氣惡劣，但隨著各類智能保暖產(chǎn)品的問世，冬天也能變得舒適宜人。D.Ways of keeping warmB.s the best title of this passage?
