一、在句中起名词作用的从句叫名词性从句，它包括主语从句、宾语从句、表语从句和同位语从句。如：whether he will come here or not is unimportant to me.（主语从句） i don’t know what he means.（宾语从句） i’m glad that you are here.（宾语从句用在形容词之后） the teacher is satisfied with what you have done.（介词宾语从句） that was because he was ill.（表语从句） the news that he got killed in the race surprised us all.（同位语从句）
