8、DsignSection II Reading ComprehensionPart ADirections:Read the following four texts. Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1 If humans pump enough carbon dioxide (CO2) into the atmosphere, the stratocumulus clouds(层积云 )
9、could disappear, and the earths temperature could climb sharply to heights not predicted in current climate models. It would burn the planet. Thats the conclusion of a paper published in the journal Nature Geoscience and described in detail by Natalie Wolchover for Quanta Magazine.As Wolchover expla
10、ined, clouds have long been one of the great uncertainties of climate models. Computer models that easily capture the complexity and detail of most climate systems just arent powerful enough to predict worldwide changes in cloud behavior. But clouds are important. They reflect sunlight away from the
11、 earths surface. And stratocumulus clouds are those white blankets you might have seen as you looked out the window of arm airplane, rolling out below you and hiding the ground Researchers suspect that certain sudden, past jumps in temperature may have been caused by changes to clouds like these.For
12、 the new research, scientists modeled just a small patch of sky using a supercomputer. They found that if carbon dioxide levels reach about 1, 200 parts per million(ppm) in the atmosphere, stratocumulus clouds break up. Thats a very high carbon dioxide concentration. Right now, levels have climbed p
13、ast 410 ppm-a dangerous change from 280 ppm before the Industrial Revolution.But humans put more and more CO2 into the atmosphere every year. If current trends continue, the earth could reach 1, 200 ppm within 100 to 150 years. This could happen if our society doesnt follow through on any of its com
14、mitments to reduce emissions(排放), Wolchover reported. And even if it does, the result would be another 8 degrees Celsius of heat added to the global average, on top of the dangerous changes already underway due to greenhouse gases.Thats an enormous change, and it goes beyond predictions of worldwide
15、 ice melt and catastrophic sea level rise. And, once the stratocumulus clouds are gone, Wolchover reported, they likely wouldnt reappear until atmospheric carbon dioxide levels dropped below where they are currently.Theres still some uncertainty in the data. The 1, 200 ppm figure could change as scientists look into the issue further.1、What can we learn from paragraph 2?AMost climate systems are not complex.BCloud behavior is uncertain and hard to predict.CTemperature changes affect the stratocumulus clouds.DThe stratocumulus clouds protect planes from sunlight.2、Ho
