问题 How many Earths could fit inside the Sun? [br] What does our atmosphere do?
选项 A、It absorbs the heat from the ground and sends it to the Sun.
B、It absorbs the heat from the Sun and emits it back to the Earth.
C、It absorbs the heat from the Sun and emits it the same way.
D、It absorbs the heat the ground emits and sends some of it back to the Earth.
答案 D
解析 根据题干信息词our atmosphere定位到第二个小标题下的第二段末句Our atmosphere does the same thing--it absorbs the heat that the ground emits and sends some of it back to the Earth。本题问，大气的作用是什么?根据文章表述，地球吸收来自太阳的热量然后释放，就像夏天里太阳落山后路面还持续放热一样，大气也在做同样的事——吸收地面的热量，然后再把一部分返回到地面，故本题选D。
