he spoke so quikly that i did't catch what he said.这句中所有语法

问题描述:

he spoke so quikly that i did't catch what he said.这句中所有语法

so that 是固定的搭配
what he said 是做宾语从句,作catch的宾语。

so。。。that
catch something 听懂

整体上说这是一个由so ....that....引导的状语从句, that后面是一个宾语从句,what he said作catch的宾语.时态为过去式,意思是:他说话太快了以至于我没有听到他说什么。

1、一般过去式 spoke
2、so···that···句型 前后时态一致
3、what引的导宾语从句

so.that
catch something 听懂
