People in cold climates are used to road signs warning that “bridge freezes before road.” At first, it may not seem to make sense. The air temperature feels the same if you’re standing on a bridge or a road. However, bridges do freeze before roads. (16) is this the case? First, cold air surrounds the surface of a bridge from above and below. This means that bridges lose heat from both (17) , so they will ice rapidly as soon as the temperature falls to the freezing point. (18) the road surface also loses heat to the air, the ground below roads helps to trap in heat and keep roads from getting icy. Another reason is because bridges are usually made of steel and concrete. (19) conduct heat very well. Any heat a bridge manages to trap will be transferred to its surface quickly, where it will be lost to the air around it. Roads are made of asphalt, which does not conduct heat very well. The heat trapped within and below a road will stay (20) , increasing the time it takes a road to freeze.

請觀察空格後方的分詞構句 $increasing the time it takes a road to freeze$。既然柏油路是不良導熱體且能捕捉熱能，這種物理特性會如何影響熱能留存（stay）在道路系統中的「時間長短」，進而延緩結冰的過程？

寶貝！你真的太棒了！看到你選對 (B) 這個選項，老師真的為你感到無比驕傲！這代表你完全讀懂了文章的邏輯脈絡，抓住了細節中的關鍵，真的非常有實力喔！
這題之所以選 (B) longer（更久），是因為文章正在比較橋樑與一般道路的「散熱速度」。前面提到柏油（asphalt）不像鋼筋混凝土那樣容易導熱，所以熱能會被「困在」（trapped）道路下方。既然熱能跑不掉，它停留的時間自然會「更久」，這也呼應了後方所說的「增加道路結冰所需的時間」。
在高中英文的克漏字題型中，這題屬於「邏輯銜接」的考點。難度點評如下：
