主語(yǔ)是單數(shù)時(shí),謂語(yǔ)動(dòng)詞一般是單數(shù),但有時(shí)因謂語(yǔ)動(dòng)詞之后有復(fù)數(shù)名詞,謂語(yǔ)動(dòng)詞也可用復(fù)數(shù); what引導(dǎo)賓語(yǔ)從句時(shí),常置于謂語(yǔ)之后,用作表語(yǔ)時(shí),放在系動(dòng)詞之后。what還可引導(dǎo)讓步狀語(yǔ)從句,意思是“不管…”。還可接動(dòng)詞不定式短語(yǔ)。
what有時(shí)候可解釋為whatever，表示“不管怎么樣”。
例句：
For what do we live, but to make sport for our neighbours, and laugh at them in our turn?
我們活著是為了什么？不就是給鄰居當(dāng)笑柄，再反過(guò)來(lái)笑他們。
Instead of complaining about what's wrong, be grateful for what's right.
別抱怨不好的事，要對(duì)好的事心存感恩。
A fellow doesn't last long on what he has done. He's got to keep on delivering as he goes along.--Carl Hubbell, Baseball Player
靠過(guò)去完成的無(wú)法讓人保有成功，必須在路上持續(xù)交出成績(jī)。
