Being so weak, you might as well see a doctor.
都这么虚弱了,你最好去看看病。
might (just) as well: (通常用于口语)用来建议做并不是太想做的事情,由于没有更好的选择、又只能如此(used to suggest doing something that you do not really want to do, because you have no better ideas.)。这个搭配的表达有点像汉语中的让步状语从句,经常会在翻译中加上“既然”“反正”之类的词加强相应的语气。
例句:
You'll need a new suit at Spring Festival anyway, you might as well have it now.
反正你春节也得添一套新衣服,还是现在添了吧。
Since Jack wouldn't take up the job, we might as well ask Richard to do it.
既然杰克不愿意承担这个任务,我们只好请理查德来干了。
