A是eat 的不定式形式,B是动名词,C是将来进行时,D be eaten是被动语态,被吃.
由句子可以看出空格部分在句子中主语,是个选项中A、B可以做主语.
to do做主语和doing做主语的区别:
1.to do 一般情况下是用it做形式主语.例:It is rude to turn your back to your teacher and refuse to answer.
2.动名词作主语表示一般或抽象的多次性动作,不定式作主语表示具体的或一次性的动作,特别是将来的动作.例如:
_______ is a good form of exercise for both young and old.
这里不能写to walk,而只能是walking.
