一个英语语法问题
我在看书时,经常看到to be后面加ing,例如 Lucky Edward happen to be standing next to me这样的、随便问下Charlie trying to be attentive 不定式后可加形容词?

Answer 1

不定式有三种时态.即一般式to do 进行式to be doing和完成式to have done 它们一般和一些特定的动词连用.如seem /appear/pretend后和it is said/reported,等后面常用这三种时态.如
His mother seems to have known about it .
=His mother seems to have been told about it .
Tom pretended to be reading when his teacher came in.(老师进来汤姆假装在看书)
The book is said to have been translated into several languages.(据说这本书已被译成几种语言.动词译在动词说之前就已发生所以用完成时且被动)
Tom is said to have graduated from college.(所说汤姆已大学毕业了)
你所问的动词try后可接的不是形容词而是系动词原形后加的形容词,如 try to be careful .而不是try to careful.
