某些表示情感的形容词,后面既可以跟不定式,也可以跟that从句。如果前后的主语为同一人,用不定式结构或that从句结构都可以,往往可以相互转换;如果前后的主语不是同一人,就要用that从句。
初中英语中应掌握的这种用法的形容词主要有:glad (高兴的),happy (高兴的),afraid (恐怕,害怕),sorry (难过的,抱歉的),pleased (高兴的),surprised (吃惊的)。
I am glad to see you back. 我很高兴看见你回来 。(主语为同一人,相当于:I am glad that I see you back.)
I am glad that you are back. 你回来了我很高兴 。(主语不是同一人 )
We are happy to meet you here. 在这里遇见你我们很高兴 。
We are happy that we meet you here.
We are happy that you have passed the exam. 你通过了考试,我们很高兴 。(不可改用不定式结构 )
I am sorry to trouble you. 很抱歉打扰你 。
I am sorry that you have to leave. 你不得不离去我很难过 。
I am surprised that there are so many people in the shop. 商店里有这么多人我感到很吃惊 。
转化为 :I am surprised to see so many people in the shop.
