• 关于非谓语动词用法的补充说明
• 1.不定式作宾语，其后跟宾语补足语时，常用“it”作形式宾语，
把不定式后置。
• I think it essential to reserve air tickets.
• I made it a rule to do shadowboxing every morning.我养成了每天
早晨打太极拳的习惯。
• 2.know 用于主动语态，特别是用于一般过去时和完成时态时，
其后作宾语的不定式在英式英语中可省去。
• I never knew him do anything without a very good reason.我知道
他做任何事情都有充分的理由。
• 用于被动态时不能省：
• I have never known that man ( to ) smile.
• That man has never been known to smile.
• 类 似 的 ： judge/suppose/consider/discover/imagine/
prove/understand, etc.
• 3.并列不定式:通常前一个加“to”，后一个省略；但如有对比关
系，都带“to”。
• It is better to give than to take.
• We ought to read more and have more practice.
• I haven’t decided whether to quit or to study.
• 4.现在分词一般式一般不作定语，除非为非限制性定语。
• This is the question having been discussed for thousands of years.
