Question

It is unhealthy _______ us to eat too much sweet food and it is wrong _______ us to buy sweet food every day.

A. of, of B. for, of C. of, for D. for, for

 

Answer 1

B

【解析】

试题分析：句意：吃太多的甜食对我们是不健康的，而且没人买甜食是错误的。句型It is +形容词+ for sb.to do sth.做某事对某人来说……；但如果形容词是表述某个人的属性，特征时，往往用介词of，如It’s kind of you to help me.结合语境故选B。

考点：考查介词。
