TPO23 reading1 第五題 - 英檢

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.



5. According to paragraph 3, why do materials in the countryside have a lower
heat capacity than materials in cities do?
○ The countryside in the Sun is the only important source of heat.
○ Construction materials in the city are not as good at keeping
buildings warm as they are in the countryside.
○ In the countryside the solar heat that flows into the ground flows out
again quickly.
○ Countryside vegetation prevents heat from being trapped in the ground.

答案是四
我只對第四個選項有疑問 他說植被可避免熱被限在地面
跟上面最後一句說植被可避免熱可以輕鬆的來回地表
這兩個意思 解析說是一樣 可是我怎麼看都是相反.

植被可避免熱被限在地面 不就表示熱可以來回地面嗎?
這樣怎麼會一樣? 求神人解除迷或謝謝!!!!
