A.Fewer B.less C.cheap D.short

——Why didn't you buy the MP4you had wanted
—— I had planned to.,but I was $30( ) A.Fewer B.less C.cheap D.short选D.句子意思：——你为什么没有买你想要的那个MP4?——我本来计划要买,但是我的钱少三十美元.选项辨析：A.Fewer 更少的,修饰可数名词,而所给搭配后面是钱数,不可数名词.排除.B.less 更少的,原形是little,意思不合适.C.cheap 便宜的；廉价的.主语是事物,不是人.排除.D.short.
短的,矮的,【不足的,不够的,】 (智力等)弱的,浅薄的,按照句子意思,这里需要表示【（钱数）不足、不够】.祝你开心如意!

选D，表示短缺，

D.short 表示钱不够
