　　2.做宾补：

　　不定式可以表示一次性、具体性行为，以及将来意义的行为。现在分词可以表示当时正在发生的进行意义的行为，亦可表示-个持续时间的延续性的行为动作。过去分词可以表示完成意义的行为或状态，及物动词的过去分词亦有被动意义，不及物动词的过去分词仍是主动意义。

　　3.做表语：

　　不定式和动名词做表语解释主语内容，且可以和主语颠倒，意思仍然通顺，回答what的问题。它们有时存在经常性和一次性行为的区别，分词做表语表明主语的性质、特征和状态，不能和主语颠倒，可以回答how的问题。

　　Our job today is to clean the office.(=To clean the office is our job today.)

　　The news is very exciting.(How is the news?)

　　They are very tired after a long walk.

　　The door is locked now.

　　The children are well dressed these days.

　　4.做定语：

　　不定式做定语与先行词有动宾、主谓和解释先行词内容等关系。在时态上常是将来意义，现在分词做定语是现在时或进行时态意义;过去分词做定语则是完成时态意义。此外，不定式做定语时只能后置，不可前置，而单个分词做定语可前置，分词短语做定语则须后置。动名词做定语，须前置，且要重读，它表明先行词的用途。而分词做定语表明先行词的性质、特征和状态。

　　a swimming boy=a boy who is swimming a swimming pool=a pool for swimming

　　The house being built (=which is being built) now will be our new library.

　　The house built (=which was built) last year is our new library now.

　　5.做状语：

　　不定式和分词做状语各有不同分工。动词不定式多做目的、结果和原因状语，且多放在句末;分词

　　可以表示时间、原因、条件、让步、方式状语，多置于句首，做伴随状语，多放在后面。分词用于go doing结构中作目的状语。

　　(1).目的状语：通常有不定式表示，由于不定式的客观性和将来性特征。不定式前还可加上in order，so as来加强说话的口气。但so as to通常不用于句首。

　　The Smiths have gone to London to spend their holidays.

　　I came here (in order/so as) to hear the report.

　　In order to(不用so as to) see better, we took front seats.

　　(2).时间状语：分词作时间状语相当于时间状语从句。现在分词作时间状语一般位于句首，表示的动作和谓语动词的动作同时发生，有时现在分词前可以加上时间连词。如果分词动作发生在谓语动词之前，用现在分词的完成体形式。过去分词作时间状语与谓语动词构成同时性和被动意义。分词前有时加上时间连词。

　　Arriving (=When he arrived) at the bus stop, he found his sister there.

　　Waiting (=When I was waiting) to see the doctor, I met with a friend of mine.

　　Having (=When we have) made full preparations, we are ready for an examination.
