Question

I have a lot of work to be done.我有许多工作要完成。有语法问题吗？

如果理解work与不定式构成逻辑上的动宾关系，是不是也应该用主动形式表示被动意义？
原题语境是I have a lot of work to be done，so I'm afraid i can't go to the party.

Answer 1

I have a lot of work to be done.我有很多工作要（让别人）做。
I have a lot of work to do.我有很多工作要做。这是非谓语结构中动词不定式主动表被动，胆动作发出者仍是主语 I

在一种情况下两者意思一样，既：There is a lot of work to do/to be done。（没有出现具体动作发出者的情况下）

Answer 2

I have a lot of work to be done 我有许多事情要做 （请人做）
I have a lot of work to do.我有许多事情要做 （亲自做）

Answer 3

如果是work作主语，工作是被做
there is a lot of work to be done才用to be done，
