题目

to do to be done
使用to do来表示被动是因为：用这个不定式结构作宾补.这个不定式表示将要发生的动作.和主语名词有逻辑上动宾关系【很重要】
但是,There are many things to do 动作和主语名词有动宾关系吗?怎样的关系?
又如,For teenagers,there are always too many rules that are expected_____
该用to obey 还是to be odeyed

答案

1.句中未体现出主语,主语为某人,There are many things(for someone) to do.这样就好辨别了,宾语many things,动词do.
2.to be odeyed
