In fact Are you worried that these three types of jobs won39。So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.（1）What is the main purpose of paragraph 1? A.To stress the importance of good memory.D.Be inferior toBe related to（3）Which of the following jobs is the most likely to be replaced? A.The psychologist.（4）Which of the following suggestions can the author give about job replacement of AI? A.Upgrade people39。根據(jù)第一段可知一個名叫奈杰爾而后文主要與人工智能有關,由此推斷作者寫第一段的目的是引出人工智能這個話題。結(jié)合下文推斷人工智能能夠具有取代人類的工作是因為AI在日常任務中表現(xiàn)超過了人類,劃線詞的意思是勝過,超過,故選A。人工智能不可能像科學家,小說家和藝術家那樣進行發(fā)明創(chuàng)造。 （4）考查推理判斷。5．Directions: Choose the one that fits best according to the information given in the passage you have just read. 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.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.s Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica39。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? Used to Be Much Greener Once Experienced Warm Periods Cities Warned of Coming Disasters Greenland, A Perfect Destination【答案】 （1）C（2）B（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了在古代沉積物中發(fā)現(xiàn)的一條微小線索揭開了格陵蘭島過去和未來氣候的大秘密。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為的還要熱。根據(jù)第三段中的“This new information could help researchers better measure Greenland39。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,’” （4）考查主旨大意。 【點評】本題考點涉及細節(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，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。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。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. . 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，城市規(guī)模的擴大，印度的新德里成為世界上污染最嚴重的城市。s most polluted city.” 新德里每年都會被污染吞沒，隨著天氣變冷，汽車和以煤為基礎的發(fā)電廠排放的污染物、建筑工地和道路上飄動的灰塵，以及鄰國農(nóng)作物秸稈燃燒產(chǎn)生的煙霧，都會形成濃霧。故選B。由此可知，由于污染嚴重，學校、大學、醫(yī)院和市場分發(fā)了數(shù)百萬個防污染口罩。因為天氣變冷，從汽車和以煤為基礎的發(fā)電廠“emitted”的污染物形成了厚厚的霧霾。 （4）考查主旨大意。 【點評】本題考點涉及推理判斷，詞義猜測和主旨大意三個題型的考查，是環(huán)保類閱讀，考生需要根據(jù)上下文的邏輯關系，進行分析，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.1
