托福tpo23阅读第一篇第五题求解
The first is the heat capacity of the materials that constitute the city,which is typically dominated by concrete and asphalt.During the day,heat from the Sun can be conducted into these materials and stored—to be released at night.But in the countryside materials have a significantly lower heat capacity because a vegetative blanket prevents heat from easily flowing into and out of the ground.
解释说文中没有提到construction materials 但是materials that constitute the city不是一样的么
而且答案d说vegetation prevent heat from being trapped in the ground和文中的prevent heat from flowing into and out of the ground 不是矛盾的么?(prevent from flowing out就是prevent being trapped in the ground)
