Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on faroff sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground.

Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, watts per square meter of area burned are soaked up by the earth from greenhouse gases, but watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.（1）According to the new findings, taking steps to prevent northern forest fires may ________. A.ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about northern forest fires ________. A.absorbedallow more snow to reflect more sunlight into space and thus cool the climateC.故選C。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇環(huán)保類閱讀，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，從而選出正確答案。 The artificial intelligence (AI) system, developed at University College London and set to be piloted in NHS hospitals later this year, will screen at risk patients so doctors can take early action to prevent death or serious illness. Prof Young, a consultant surgeon at Southend University Hospital, said: I am so excited about this form of technology. Instead of people getting sick or dying because they are not picked up in time, this will allow us to step in earlier which will save lives and an enormous amount of money. 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.B.By observing changes in blood cells.To stress the importance of health care.C.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”。故選A。 While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭氣) too.being plain in taste at the discovery of a predatorB.vulturemillipede故選C。然而，它們也會釋放出有害 的 Although John Wilkins, an Englishman, first put forward a decimal system (十進制) of measurement in 1668, it was the French who in 1799 made it law.

A. （2）考查主旨大意。 If plastic had been invented when the Pilgrims sailed from Plymouth, England, to North Americaand their Mayflower had been stocked with bottled water and plastic wrapped snacks, their plastic waste would likely still be around four centuries later. Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world39。 No one knows how much unrecycled plastic waste ends up in the ocean, the earth39。 This isn39。s the main trouble marine animals face according to the text?
