what其他用法：

1、what +主语+不及物动词/系动词+介词

例句：The judge does not consider what each eyewitness looks like.

解析：what each eyewitness looks like是宾语从句，what在从句中作介词like的宾语。

2、What+主语+及物动词

例句：What he says is reasonable.

解析：What he says是主语从句，what 在主语从句中作宾语。

例句：It is none of your business what other people think about you. Believe yourself.

解析：本句意为“别人怎么看你，与你无关，相信你自己。”其中It是形式主语，真正的主语是what other people think about you.
