Question

i know he did not tell you that he would come then

i know he did not tell you that he would come then. he did not tell you 做什么成分呢，是宾语从句，省略了that吗？后面的that he would come 是宾语从句，做的谁的宾语呢？

Answer 1

这个句子有两个宾语从句，在宾语从句中又引出了另一个宾语从句。
第一个宾语从句是( that) he did not tell you that he would come then, 这里省略了that，这个从句作know的宾语。
第二个从句是在第一个从句里面的that he would come then，这个宾语从句作tell的宾语。
