A. that B. which C. this D. what
题目解答
答案
B
解析
步骤 1:分析句子结构
句子的主干是"The postman comes at 6:30 in the morning",后面的部分是定语从句,修饰前面的时间"6:30 in the morning"。
步骤 2:确定定语从句的引导词
定语从句中缺少时间状语,因此需要一个可以引导定语从句并且在从句中作时间状语的词。选项中,"that"和"which"都可以引导定语从句,但"that"不能引导非限制性定语从句,而"which"可以。因此,选择"which"。
步骤 3:验证句子
将"which"代入句子,句子变为"The postman comes at 6:30 in the morning, at which time I am usually fast asleep.",句子语法正确,意思通顺。
