regard as 的用法
问题描述：
regard as 的用法
( ) as a famous scientist, he was offered a good post at a university.
A. regarded
B. having been regarded
请问各位高手,应该选哪个呢?答案是A,可是如果从时间顺序理解,B应该是比较合适的.那到底是怎样呢,先谢谢啦!
答
选 A regarded 这是过去分词做状语表示被动和已经.所以不用B.having been regarded
因为这是现在分词完成时态的被动式.表示某一动作已完成或持续了多久.常有一个时间状语在分词后.下面给你两个例子你会明白.
Given more time ,we could do it better.=If we were given more time ,we could it better.
Having been taught several times ,he still couldn't answer the question.= Although he had been taught several times ,he still couldn't answer the question.
