参考答案：
【答案】
1．C
【详解】句意：——现在几点了？——两点半。
考查时间表达法。英语时间表达方式：“基数词+o’clock”表示整点；用基数词按“小时+分钟”的顺序直接写出时间；如果分钟数少于30分钟，可用“分钟+past+小时”表示；如果分钟数多于30分钟，可用“（60-原分钟数）+to+（原小时数+1）”表示；如果表示半点，可用结构“half past+小时”。结合选项可知，选项C“两点半”符合。故选C。
2．C
【详解】句意：我们学校有一个大图书馆。里面有成千上万的书。
考查大数的表达。当thousand与数词连用时，表示一个具体的数字，后面不加s；当thousand与of+复数名词连用时，表示一个多而不具体的数字，后面加s。 根据“There are…books in it.”可知，此处可以泛指成千上万的书，只有thousands of“成千上万”表述正确。故选C。

5．B
