在there be句型及with的復(fù)合結(jié)構(gòu)中，可以用主動(dòng)形式表被動(dòng)意義。

例如：

There is nothing to read. \ There is nothing to worry about.

With so much work to do, Mary cannot but stay at home.

There is nothing doing these days. 這些天沒(méi)事干。

I see there’s a good idea planning. 我知道又在打好主意。

在“疑問(wèn)詞what/which/whom+不定式”結(jié)構(gòu)中，有時(shí)以主動(dòng)形式表被動(dòng)意義。

例如：The question is which to choose.問(wèn)題是挑選哪一個(gè)。

He will advise you what to do.他會(huì)建議你們做什么。

在“too...to...”結(jié)構(gòu)中，用主動(dòng)形式表示被動(dòng)意思，此時(shí)不定式前面可以加邏輯主語(yǔ)。

例如: The box is too heavy (for me) to carry.這盒子太重了,搬不動(dòng)。

The room is not enough (for us) to have a meeting in.這個(gè)房間不是大到足夠能在里面開(kāi)會(huì)。
