【习题】图中b处气温比同纬度平原地区低的主要原因()①到达b处的太阳辐射少②b处的地面辐射弱③b处大气吸收的地面辐射少④b处大气的保温作用弱A.①②B.③④C.①④D.②④【争论】在一堂“气温”复习的公开课上,授课教师选用了上述习题,并通过讲解得出参考答案为B选项。评课阶段,有教师对②选项是否错误提出了疑义。随后,听课教师以我国青藏高原为例,就其地面辐射是否比同纬度平原地区弱;如果弱,这是否是高原气温低的
【Problem】 The main reason for the lower air temperature at b than in the same plain (a) ① Less solar radiation reaching b. ② Less ground radiation at bb. ③ Less ground radiation absorbed by atmosphere at ④. B. ①②B.③④C.①④D.②④ 【Argument】 In an open class of “Temperature” review, the lecturer selected the above exercises and explained that the reference answer is B option. During the assessment stage, some teachers raised doubts about whether the ② option is wrong. Subsequently, the lecture teacher taking the Qinghai-Tibet Plateau of China as an example, weaker whether the ground radiation is lower than that in the same plain area or not; if it is weak, is this a low-altitude plateau?
