4、ature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated(低估)the speed of flowering by 8.5 times and leafing by 4 times.“Across all species, the experiments under-predicted the speed of t

5、he advance for both leafing and flowering that results from temperature increases,” the study said.The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.Plants are necessary for life on the Earth. They are the base of the food cha

6、in, using photosynthesis(光合作用)to produce sugar from carbon dioxide and water.

The increasing speed of flowering is beyond scientists expectation.C. Climate change leads to the change of food production patterns.D. Food chains have be

12、文章论述了全球变暖的气候环境会让植物提前生长开花,进而影响整个食物链及生态系统。57. B 细节理解题。第一段话给读者传达的主要信息存在于主句,而不是 which 所引导的定语从句上。根据“Plants are flowering faster than scientists predicted”可知,作者是要告知读者植物开花的增速超出了科学家的预期。故选 B。A 为次要信息。258. C 推理判断题。第五段话“It found that some experiments had underestimated(低估)the speed of flowering by 8.5 times and

13、 leafing by 4 times”暗示读者:对于植物所设计的实验应该有所改进,故答案选 C。59. B 细节理解题。根据第四段“They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services”可知植物对气候变化的反应对整个食物链和生态系统都至关重要。故答案选 B。60. D 推理判断题。从倒数第二段“has risen by about 0.8 since
