25、定式的复合结构动词不定式的复合结构动词不定式的复合结构是“for/of sb.to do sth.”。不定式复合结构的介词用for还是of,主要决定于前面形容词的性质。一般说来,of前面的形容词是careful,clever,foolish,good,kind,nice,wise等,说明人的特性。for前面的形容词是dangerous,difficult,easy,hard,heavy,important,interesting,necessary等,一般说明不定式动作的特性,前面如果是名词用for。如:Its a good idea for parents to allow children
26、 to study in groups during the evening.Its wise of him to do it well.带疑问词的不定式短语带疑问词的不定式短语动词不定式前面可以带疑问代词what,which,who或疑问副词how,when,where,why等。这种结构起名词的作用,在句子里用作宾语、主语、表语等,或者单独使用。要注意的是,why后面的不定式不带to。如:(1)用作句子的成分。I dont know what to try next.(作宾语)Where to go is not decided yet.(作主语)(2)单独使用时相当于一个特殊疑问句。Wh
27、at to do next?=What will we/you do next?Why go there?=Why do we/you go there?不定式的否定式是not/never to do.;不带to的不定式的否定式是not/never do.如:They decide not to talk to each other.His parents tell him never to play soccer in the street.Part 5动名词(动名词(doing)用作主语用作主语动名词相当于名词,在句子中可以做主语、宾语、表语、定语等。Fighting broke out
