一道英语题与时间状语从句与强调句有关
It is about 9:30 ____he comes back after three evening dasses.
A when B before C that D since
when,理由?

Answer 1

此句不是强调句.强调句的话应该做成：It is at about 9:30 that he comes back after three evening classes.
强调句的特征是,去掉it,is,that之后,整个句子可以不缺成分地连在一起.
个人认为,这道题理解成状从或定从都是可以的.
状从的话,明显是时间状语从句,根据句意when合适.
定从的话,先行词是9：30,从句中缺状语,先行词是时间,因此选择关系副词when.
