If I were you, I'd skip it. We both have to get up early tomorrow and anyway, I've heard it's not as exciting as advertised.
重点
本句是个建议句型。if I were you为虚拟语气形式,表示对现在情形的假设,意为“如果我是你的话/换成是我(我会做某事)”。
skip it相当于stay out of it,意为“避开,躲开”,在口语中通常用于指“不参加(活动)等;避开是非”。如:
My father told me to stay out of/skip trouble. 我父亲叫我避开是非。
考点归纳
与if I were you类似的句型还有:
if he/she were意为“如果/要是他/她……”。如:
If he were here, everything would be all right. 如果他在这,一切都会好的。
if I were in your shoes意为“如果我站在你的立场上/与你的角色互换”。如:
If I were in your shoes, I would sue him. 我要是你,就告他。
