這是有關(guān) well 不同搭配作狀語的兩個(gè)方面的問題——
1. 作“有理由地、可能地”講,與情態(tài)動(dòng)詞 may/might/can/could 搭配表示“有充分的理由可以”或“有可能”.如：
You may well say so. 你很有理由這樣說.
We might well make the experiment. 我們該做那項(xiàng)實(shí)驗(yàn)了.
It may well be that he will do so. 那很可能是他要這樣做.
I can't very well manage to come tomorrow. 明天我不大可能來.
2. 作“正確地”或“恰當(dāng)?shù)亍敝v——
1）與副詞 as 搭配表示“最好,倒不如, 還是...的好.不妨”,may/might 只是表明說話人個(gè)人認(rèn)為可以的態(tài)度.如：
It may be as well to stop that young screamer. 但是最好還是讓那個(gè)大哭大叫的孩子住聲.
You may as well say so. 你不妨可以這樣說.
We might as well make the experiment. 我們倒不如可以做那項(xiàng)實(shí)驗(yàn)了.
2）用在比較結(jié)構(gòu) as well…as…中,如：
It may be as well to stop that young screamer right away as usually.但是最好還是可以像通常那樣立刻讓那個(gè)大哭大叫的孩子住聲.
You may as well say so as you please. 你不妨可以隨你的意思這樣說.
3) 用在 may/might just as well 中強(qiáng)調(diào)“最好、不妨”,表示“幸好可以, 也無妨”,如：
You may just as well say so. 你這樣說也無妨.
We might just as well make the experiment. 我們幸好可以做那項(xiàng)實(shí)驗(yàn)了.
補(bǔ)充回答
1. may/might as well 和may/might just as well 前者表示“倒不如可以（做某事）,不妨可以（做某事）”,后者語氣較強(qiáng),表示“幸好可以（做某事）, （做某事）也無妨”,后者替換前者后在意思上有所強(qiáng)調(diào).（見上面的例句）
2. may/might as well…as… 表示“如同...一樣,最好/不妨可以（做某事）”（見上面的例句）
