使役动词和感观动词后接sb do 如,let sb do make sb do have sb do
see sb do hear sb do watch sb do notice sb do
其它动词后接sb to do 如 ask sb to do tell sb to do want sb to do warn sb to do
help sb to do allow sb to do 等.

为什么动词后有的接sb to do sth 有的接sb do sth? 为什么有的动词后加动词ing 有的加 to do sth ( ) sb.to do sth. help 后边接动词不定式还是动词原形?有没有help sb,do sth.help sb,to do sth,help do sb.to do sth. want sb to后面接do sth还是doing sth 我的意思就是有的词组+to 例如 teach sb to do sth 有的却没有to 例如 let sb do sth let sb to do sth 对吗?为什么为什么没有：hope sb to do sth 为什么Allow sb to do sth,Ask sb to do sth就有to,而Let sb do sth ,H sb wishes to do sth.sb hope to do sth. invite sb to do sth
