题目内容
I bought my younger sister a toy with my pocket money，________that is cheap but beautiful.
| A．one | B．the one | C．this | D．that |
A
解析试题分析:考查不定代词。从结构可知后面部分不是句子，而是不定代词做toy的同位语，that is cheap but beautiful是定语从句，修饰前面的不定代词，所以排除C、D选项；而前面名词是a toy，泛指概念，所以用one代替。故正确答案为A。句意：我用零花钱给我妹妹买了个玩具，一个很便宜但是很好看的玩具。
考点：考查不定代词。
