【文章內(nèi)容簡介】 A.It helps patients recover earlier.B.It has helped save thousands of lives.C.It will promote the health service greatly.D.It is intended for patients with kidney diseases.【答案】 （1）C（2）C（3）A（4）C 【解析】【分析】本文是一篇說明文，介紹超級計算機能夠分析血樣并預測哪些病人可能會患上重病，每年可以挽救數(shù)萬人的生命。 （1）考查詞義猜測。根據(jù)第二段中的“so doctors can take early action to prevent death or serious illness. ”以便醫(yī)生能夠及早采取行動，預防死亡或嚴重疾病，可以猜測出，人工智能將用于對高危病人進行“篩查”。此處screen意為“篩查”。故選C。 （2）考查細節(jié)理解。根據(jù)第三段中的“Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.”可知，計算機通過檢測紅細胞和白細胞的細微變化來評估血液檢測結果。故選C。 （3）考查推理判斷。根據(jù)第二段中的I think the potential of AI in healthcare like this is as big as the Industrial Revolution was—and signals a pletely new example in the way we manage healthcare. 楊教授認為，人工智能在醫(yī)療保健領域的潛力與工業(yè)革命一樣大，以此類比，說明人工智能在醫(yī)療領域的影響力。故選A。 （4）考查推理判斷。根據(jù)最后一段中的Instead of waiting for people to get worse, we will be able to treat them earlier. 可知，這項技術將能夠更早地治療患者，而不是坐等病情惡化，從而推斷，人工智能這一科技幫助醫(yī)生對疾病診療早預判，早介入，從而幫助挽救大量生命，將大大促進衛(wèi)生服務。故選C。 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文的邏輯關系，進行分析，推理，從而選出正確答案。4．犇犇閱讀理解 Slowly but surely we39。re moving closer and closer to 5G world. From smarthome security to selfdriving cars, all the internetconnected devices in your life will be able to talk to each other at lightningfast speeds with reduced delay, Objectively speaking, the fastest 4G download speeds in the U. S. top out at an average of Mbps. But by parison 5G promises gigabit (千兆) speeds. “5G is one of those signs, along with artificial intelligence, of this ing data age,” said Steve Koenig, senior director of market research for the Consumer Technology Association. “The selfdriving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data ing from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It39。s pulling in data from other vehicles about road conditions down the lane. It could be weather information, but also connected infrastructure (基礎設施) construction. There39。s lots of data behind that task, which is why we need high speed. Augmented reality glasses and virtual headset haven39。t yet broken the mainstream, but tech panies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones. Ericsson stated at February39。s Mobile World Congress how smart glasses could bee faster and lighter with a 5G connection, because instead of being weighed down with ponents, the glasses could rely on hardware for processing power. But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.（1）What does the author want to stress in Paragraph 1? A.The lightingfast speed of 5G.B.The expectation of 5G world.C.The difference between 4G and 5G.D.The internetconnected devices in our life.（2）What does the underlined word emblem in Paragraph 2 mean? A.Exhibition.B.Success.C.Symbol.D.Explanation.（3）We can infer from the text that ________. A.5G world won39。t e without AR glassesB.5G helps to create the artificial intelligence vehicleC.Apple pany is developing AR glasses worldwideD.Tech panies will face the fact that smartphones may be replaced（4）What will the author probably tell us next? A.How to fully expand 5G coverage.B.Smart glasses will bee faster and lighter.C.Why 5G isn39。t concentrated in big cities.D.The importance of infrastructure construction.【答案】 （1）A（2）C（3）D（4）A 【解析】【分析】本文是一篇說明文，介紹了我們離5G世界越來越近了。 （1）考查段落大意。根據(jù)第一段中的“Slowly but surely, we39。re moving closer and closer to 5G world.”緩慢但肯定的是，我們離5G世界越來越近了?？芍?，作者在第一段想強調(diào)“5G光速快?！惫蔬xA。 （2）考查詞義猜測。根據(jù)第二段中的“and that is to say, it is a sign of tim”也就是說，這是時間的標志，”可知，劃線詞的意思是“標志，象征”。故選C。 （3）考查推理判斷。根據(jù)第三段中的“This is notable because panies such as Apple are reportedly developing AR glasses to assist — or perhaps even replace — smartphones.”這一點值得注意，因為據(jù)報道，蘋果(Apple)等公司正在開發(fā)增強現(xiàn)實眼鏡，以幫助——甚至取代——智能手機?！?可知，我們可以從文中推斷，科技公司將面臨智能手機可能被取代的事實。故選D。 （4）考查推理判斷。根據(jù)最后一段中的“But don39。t get too excited. There39。s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn39。t concentrated only in big cities.”但是不要太激動。與此同時，仍有很多工作要做，包括各種試驗，以確保收音機能很好地配合硬件和基礎設施建設，這樣5G就不會只集中在大城市?！笨芍?，作者接下來可能會告訴我們“如何全面擴大5G覆蓋?！惫蔬xA。 【點評】本題考點涉及段落大意，詞義猜測和推理判斷三個題型的考查，是一篇科普類閱讀，要求考生根據(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。5．犇犇閱讀下列短文，從每題所給的A、B、C和D四個選項中，選出最佳選項。 One spring day, once the flowers have begun to open, a bee will hover (盤旋) and zip through your yard and divebomb your piic table. While you39。re thinking about avoiding an attack, that bee is focused on something else entirely: me. A honeybee has about six weeks to live. Today, like most days, her task is to fly as many as three miles from home, stick her long, strawlike tongue into a hundred or so flowers. When the bee has had her fill, shell fly home. There the bee will deposit what she has got into the mouth of one of her coworkers, who will relay it to another, and so on for about 20 minutes, until the mixture is ready to be placed into the b. Then she and her 50 000 or so mates will hover in the dark all night every night, flapping their wings to create hot, breezy conditions to remove the water from the mixture. Several sunrises later, they will seal me off in a golden cell of beeswax. In her lifetime, our bee may visit 4, 000 flowers, and yet will produce only onetwelfth of a tea spoon of me. The average American consumes nearly a pound and a half of me every year, in tea, on toast, and beyond. If I do say so myself, I am a timeless treasure. Literally—I never go bad. Ala
