Unit1 句式精讲1. Did you do anything special last month?
本句是一个一般过去时的一般疑问句,其中的anything special意为“任何特别的事”,special是形容词,修饰anything。形容词修饰不定代词时要后置。例如:
Can you tell something interesting? 你能讲些有趣的事情吗?
Is there anybody important here? 这儿有大人物吗?
Would you like something to eat? 要来些吃的东西吗?
【拓展】复合不定代词的用法:
(1) 复合不定代词是由some-,any-,no-,every-加上-one,-body,-thing等所组成的不定代词。复合不定代词包括 something, somebody, someone, anything, anybody, anyone, nothing, nobody, no one, everything, everybody, everyone 等十二个。这些复合代词具有名词性质,在句中可用作主语、宾语或表语,但不能用作定语。
(2)复合不定代词通常被看成是单数第三人称。当它们充当句子的主语时,其后的谓语动词用单数形式。例如:
Is everyone here today? 今天,大家都到齐了吗?
Nothing is difficult if you put your heart into it.
世上无难事,只怕有心人。
(3) 由some-和any-所构成的复合不定代词(即something和anything;someone和anyone;somebody和anybody)之间的区别跟some和any的区别一样。
1) something,someone,somebody通常用于肯定句中,而anything,anyone,anybody一般用于否定句,疑问句或条件状语从句中。例如:

他发现了一些奇怪但却有趣的事情。
