省略 to 的不定式做賓補(bǔ)的動(dòng)詞有：
1、一感feel 形式： feel sb do sth \ feel sb doing sth
2、二聽 hear ,listen to 形式：hear sb do sth \ hear sb doing ;
listen to sb do sth \ listen to sb doing sth
3、三讓 let,have,make形式：let sb do sth \ make sb do sth
4、五看 see,notice,watch , abserve ,look形式： see sb do sth \ see sb doing sth
這些省略to 的不定式做賓補(bǔ),在變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)要還原to
例如：I saw Tom fall off the tree .(變?yōu)楸粍?dòng)語(yǔ)態(tài))
---Tom was seen to fall off the tree by me .
希望能幫到你
趙老師By the way~主動(dòng)為listen to sb doing和listen to sb doing sth呢?主動(dòng)有to的呢？怎么改為被動(dòng)？含有l(wèi)isten to 變被動(dòng)的很少，在英語(yǔ)中就出現(xiàn)主動(dòng)的，英語(yǔ)的語(yǔ)法你就得按照常規(guī)的去理解，否則會(huì)越學(xué)越累。
