57、Sorrows remembered sweeten present joy. ----- Pollok
不忘過去的痛苦，才能倍感今天的幸福。-----波洛克
sorrow means a feeling of sadness or distress caused esp. by loss, disappointment or regret, grief.悲傷，悲痛，懊喪，悔恨。
sorrow后常跟的介詞有at/for/over.例如：sorrow at somebody’s death因某人去世而悲傷。sorrowing over his child’s death因他孩子夭折而悲傷。
我們再來看一下這個單詞的另一個固定搭配：
more in sorrow than in anger：with more regret than anger for what was done.感到遺憾，倒并不生氣。例如：It was more in sorrow than in anger that he criticized his former colleague.他批評以前的同事，并非出于氣憤而是為他惋惜。
這句格言選自蘇格蘭宗教詩人波洛克的"時間的進程"。
58、One good turn deserves another.
善有善報/以德報德
Turn,在這里做名詞，解釋為(幫助或損害別人的)舉動，行為：do somebody a good (bad) turn.做一件有利(損)于某人的事。除此以外，turn還可以做動詞，比如：turn a somersault翻跟斗；turn somebody against another使某人與另一人作對；turn a street corner沿街角拐彎。
再來學(xué)習(xí)幾個關(guān)于turn的詞組：turn upside down，顛倒，弄亂。Don’t turn our arrangements upside down.別把我們的安排搞亂了；Turn on the tears，一下子流起淚來；On the turn，正在轉(zhuǎn)變中；To the turn of a hair絲毫不差地。
Deserve, to have earned something by good or bad actions or behavior,應(yīng)受；值得。Deserve punishment ( a reward )應(yīng)受處罰(獎賞)；deserve to be mentioned值得一提。
