Little joy can equal ______ of a surprising ending when you read stories.

C.any
D.some
网友回答
A解析思路分析：句中可用that代指前面提到过的不可数名词joy。句首的little与后面的a surprising ending when you read stories是解题过程中的关键词。that of a surprising ending相当于the joy of a surprising ending。类似的用法还有：The weather here is better than that of Beijing.这儿的天气比北京的天气要好。
【点评】该题考查代词用法，难度偏难。解题时要注意不同代词在用法上的区别。
