請問三句英文的意思及使用狀況或形容

deserve it (something) /or not deserve it (something)= to have/ or not to have earned something by good or bad actions or behaviour
e.g. What have I done to deserve this? 我做了甚麼而得到這?
Unless “deserve it / not deserve it “應得的/不應得的is explained in the context, a reader doesn’t know whether it is something good or bad. 這兩個片語, 要理解上文下理才明白其真正含意。不能單指一面的!!
e.g. You deserve a rest/ holiday/ break ----à something positive about you
You deserve some punishment ----à something negative about you
He doesn’t deserve a medal ----à something negative about him
He doesn’t deserve this punishment --à sympathetic towards him
You deserve it. (正面) =這是你應得的。
(負面/劣) =這是你的報應/這是你應得的懲罰。 = it serves you right
He doesn’t deserve it. (正面/同情)= 他不應受到這種對待。
(負面/劣) =他不配得到這。
it serves somebody right (負面)= you think somebody deserves something unpleasant that happens to them because they have been stupid or unkind.
That serves you right =這是你的報應/這是你應得的懲罰。

You deserve it = 你應得的
情況: 你下屬幫了你很多, 你放了一日假給他, 但他拒絕, 你可以講you deserve it

He doesn't deserve it = 他不應得的
情況: 今個project個個都很努力, 但只有他偷懶, 所以分花紅時, 你可以講he doesn't deserve it

That serves you right = 抵死! 你都有今日
你朋友早前取笑你, 現今佢有難, 你可以說serve you right
