①help后面作宾语补足语的动词不定式可以带to也可以不带to。 如：I often help my mother(to) do some housework.
②在使役动词后作宾语补足语，不定式不带to。有些动词跟不定式作宾语补足语时省去了to，这些动词有： 一感二听三让四观看。 一感：feel 二听：hear, listen to 三让：let, have, make 四观看：observe, see, watch, look at 这类动词有：make, let, have等。转为被动语态时，其后通常都用带to的不定式 (have没有被动语态)。 What would you have me do? 你要我做什么? She made him give up smoking. 她让他戒了烟。 Let him do whatever he wishes to do. 他想干什么就让他干吧。
