复合不定代词
something / anything 之类,修饰语必须放在后面。
something interesting(定语后置)
要点
  1. some- 类多用于肯定句,any- 类多用于疑问句和否定句。
  2. 修饰它们的形容词必须放在后面。
  3. 作主语时谓语动词一律用单数。
  4. no- 类本身含否定:nothing、nobody、none。
  5. 四个前缀横着排:some- / any- / every- / no-,各配 -thing(物)与 -body / -one(人),一共十二个。
  6. something / anything 后面常接不定式作定语:something to drink、anything to eat。
  7. nobody / nothing 作主语时,反意疑问句的附加部分用肯定:Nothing is serious, is it?
  8. none 与 nothing 不同:none 既可指人也可指物,且常与 of 连用:None of them answered.
例句
I would like something to drink.
我想要点喝的。
Do you have anything cheaper?
你们有便宜点的吗?

没什么可做的。
Everything will be free.
一切都将是免费的。

易错提示
  • 定语必须后置:something interesting,不能说 interesting something。
  • everyone、everything 作主语,谓语用单数。
  • -body 和 -one 意思一样,nobody = no one,作主语时谓语都用单数:No one is in the room.
  • 已经写了 nothing / nobody 就别再加 not —— I know nothing about it 才对,两个否定叠一起意思就翻了。
