B。【解析】考查感叹句。句意：多么糟糕的一天，雨下得太大了，我们不得不待在家里。中心词是day名词且可数，故选B。what +a/an+形容词+可数名词单数+主语+谓语!故选B。

24. — “Why couldn’t they meet us at five o’clock?”

A。【解析】考查不可数名词。句意：——为什么他们不能在5点和我们见面?——因为交通拥堵而耽搁了。对于此题，首先要明确traffic为不可数名词，没有复数形式，故排除B和D。另外，汉语习惯说“交通拥挤”，而英语习惯上却不能用crowded 来修饰 traffic，要表示汉语的“交通拥挤”，英语通常说heavy traffic，故选A。
