感官动词变被动需要加to吗

＋﹏＋ 你说的对，感官动词和使役动词的被动语态都要加to.先以使役动词make为例，The great news made her feel happy.这好消息使她很高兴.变被动，she was made to feel happy by the greatget是一般态(完整过程),而不是不定态，所以不加to 2.He was seen to get into a white car with a female. 加to是因为和谓语was seen分隔作用，删除谓语was see

?▂? 【注意】若不定式作感官动词的补足语，用于被动语态，后面原有动词原形改为带to不定式。We saw him go into the restaurant. → He was seen to go into the restaurant. I hear the同样，若是被动态，也需要加to。主动：We have never known the boy smile.我们从来不知道那个男孩会笑。被动：That boy has never been known to smile. 没有人见过那个男孩

感官动词或使役动词使用省略to的动词不定式，主动语态中不带"to",但变为被动语态时，须加上"to"。如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，在主动语态变被动语态时，书上说感官动词和使役动词变被动语态后要加to 这句话的意思是，原来的句子为省to不定式时在被动句时要把to还原也就是make/see/watch

?▂? 考点②：特殊形式的被动语态1、带双宾语的动词变被动要加to/for 直接宾语（物）间接宾语（人）巧记“直物间人”Shegavemeabook.Iwasgivenabookbyher.(将间宾me改为主语）Abookwasgiventomebyher6.感官动词和使役动词的被动语态即hear , watch , see , make , let 等词在主动句中，其后的动词不加to,但变被动句时必须加to.(主动句中to离开，被动句中to 回来) 1)I saw him

感官动词或使役动词使用省略to的动词不定式，主动语态中不带to,但变为被动语态时，须加上to。如：let,have,see,notice,watch,listen to,hear,observe,feel等。The boss makes th通常情况下，感官动词(see, notice, hear, feel, observe等)后接不带to的不定式，这些动词变被动时，需还原to。例子：see sb. do sth. (do,没有to) 看见某人做某事变被动：sb
