Question

[-B38] ______ percentage of his income is taxable?

Answer 1

看来你得记住这样一个固定搭配了：

“What percentage of.” “.的百分比是多少?”

percentage的用法是 The percentage of +sth+ is,

注意这里不管后面跟的是什么词,都用is(这里忽略别的时态) ,

类似的单词我们还学过：population.

“What's the population of.” ".的人口是多少"

“The population of .”

本句子的意思是“他的收入有百分之几的交税?”
