问题描述：
His expenditure on holidays and luxuries is rather higher in ___ to his income.
A. comparison B. proportion
答案是B翻译他在度假和奢侈品上的花销占他收入的很高一部分.
可是为什么不能选A呢?comparison的结构也是 in comparison to（ 与.相比较）可以为与他收入相比,他在度假和奢侈品上的花销太高了
答
B.proportion 为正确选项.
in comparison to 与 in proportion to 意思虽然差不多,都有“与.相比较”的意思,但用法不同.
前者不能与比较级连用,就像 Compared/ with.不能与比较级连用一样.后者可以.
