Question

Mr. Barren doesn’t think that all bad language should be allowed. In his opinion, there are ___________ that should be kept up.

A. degrees                    B. levels                       C. limits                       D. standards

Answer 1

D

解析:

定语从句that should be kept up 中的keep up 表示“保持、维持、坚持”。根据前一句的逻辑推理：Barren 先生认为我们不能容忍所有骂人的话，可以推断出“需要维持一定的标准、准则。”
