非谓语动词中 to be done和be done 的区别

to be done表示 将要被
be done并不是非谓语动词
eg.The meeting to be held tomorrow is very important.明天将要被召开的会议很重要.
继续回答吧,
done 表示“过去被,已经被,经常被”
The meeting held yesterday was very important!
再问： The meeting to be held tomorrow is very important这个句子中的to be held 应该是非谓语吧？
再答： 是啊， 明天将要被举行的会议！
