英语长难句分析
33.There are,of course,exceptions.Small--minded officials,rude waiters,and ill mannered taxi drivers are hardly unknown in the US.Yet it is an observation made so frequently that it deserves comment.
请问,Yet it is an observation made so frequently that it deserves comment.这句话,是不是made前面省略了which is,这是不是一个省略结构的定语从句.后面是不是so that 结构呢?
