问题 Flooding is the most destructive weather disaster in the last hundred years.
In the summer, the wind current will be reversed because the temperature of the air over the land turns higher than ______.
选项
答案that of the air over the ocean
解析 第4个小标题Sources of floods下Rainstorms部分的第1段第5、6句：But in the summer, the air over the land heats up, becoming warmer than the air over the ocean. This causes the wind current to reverse...空白处需要名词性成分。原文是先因后果，而题目则是先果后因，故可在第5句中寻找答案。higher和 warmer表示的都是温度高的概念，但题目的比较对象是temperature，而不是air，因此答案需要在原文than之后的名词短语前加上that of.
