你的例子已经不少了这样的词大概就是那些
1:使役动词 let,have,make:
2:感官动词 smell,see,watch,look at,notice ,observe,hear,listen to,feel,find 等后作宾补,省略to.
在被动语态中则to 不能省掉
--------------------------------------------------
The boss made them work the whole night.
=They were made to work the whole night.
以此类推,大概是:
主语+使役动词(或感官动词)+宾语+do (sth)
变为被动语态:
原来的宾语(变成主格)+ be动词(要看具体时态变化)+使役动词(或感官动词)的过去分词+to+do(sth)
---------------------照着这个句式套,(或者照着你的例句套),就可以了
