动词不定式

　　二、 不定式作宾语

　　不定式作宾语有两种：一种是及物动词后直接跟带to的不定式;另一种是“动词+疑问词+带to的不定式”

　　1. 动词+带to的不定式结构

　　只能跟动词不定式的动词，常见的有：afford， agree， aim， appear， arrange， ask， believe， care， claim， decide， decline(拒绝)， demand， desire， determine， endeavor， expect， fail， hesitate， hope， intend， learn， long， manage， mean(想要)， offer(表示愿意做…)， pretend， promise， refuse， seek(试图)， swear， undertake， wish(想要)等。

　　2. 动词+疑问代(副)词+不定式

　　这类动词常见的有：advise，decide， discuss， find out， forget， inquire， know， learn， regard， remember， see， settle， teach， tell， think(=consider)， understand， wonder等。这些疑问代(副)词有what， when， where， which， how， whether等，但不包括why，如：

　　when to speak before strangers.

　　who(m) to visit.

　　which one to choose.

　　You can decide whether to go forward or stay here.

　　when to see a doctor.
