主語是單數(shù)時,謂語動詞一般是單數(shù),但有時因謂語動詞之后有復(fù)數(shù)名詞,謂語動詞也可用復(fù)數(shù); what引導(dǎo)賓語從句時,常置于謂語之后,用作表語時,放在系動詞之后。what還可引導(dǎo)讓步狀語從句,意思是“不管…”。還可接動詞不定式短語。

　　what有時候可解釋為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，再反過來笑他們。

　　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

　　靠過去完成的無法讓人保有成功，必須在路上持續(xù)交出成績。
