在英語(yǔ)上,我們把somebody anybody nobady something anything nothing someone anyone none 等等這樣的詞稱之為復(fù)合不定代詞,在不定代詞之后,通常謂語(yǔ)動(dòng)詞用單三型式,（is was has).
復(fù)合不定代詞在句子中作主語(yǔ)時(shí),謂語(yǔ)動(dòng)詞一般用單數(shù)形式.如：Nobody knows his name.沒(méi)有人知道他的名字.
陳述部分主語(yǔ)是不定代詞everybody,anyone,somebody,nobody,no one等,疑問(wèn)部分常用復(fù)數(shù)they,有時(shí)也用單數(shù)he.This is our new headmaster,isn’t it?
