there is so much work to be done和I have so much work to do.
不定式中到底什么时候有主动什么时候用被动.
morning air is so good to beathe的原因.

如果句子的主语不是不定式的逻辑主语,则不定式需用被动语态.*i am going to the post office ,for i have a letter to post.《主动语态》(我要到邮局去,因为我有信要寄.) （句子主语i是不定式to post的逻辑主语,是我去发信,故用主动语态） A:Li ming ,i am going to the post office ,i know you have an import letter to post B:thank you ,but i have no letters to be posted now.通过对话的上下文理解之所以用to be posted 是因为句子中不是不定式主语,不是“李明寄”,而是“我”,所以用被动.
