Question

主语从句用什么引导

Answer 1

引导主语从句的连词主要有：从属连词：that、whether；连接代词：who、whoever、whom、whose、what、whatever、which、whichever；连接副词：when、where、how、why、whenever、wherever、however。

主语从句，即在复合句中充当主语成分的句子，例如"That he finished writing the composition in such a short time surprised us all"，他在很短的时间内写完作文让我们都很惊讶，此复合句主要描述的是某事让我们惊讶，某事就是该复合句的主语，因此“That he finished writing the composition in such a short time”便是该复合句的主语从句。
