at heart，by heart

這一組短語的涵義也各不相同。

At heart 的意思是“在心里”、“心底里”或“本質(zhì)上”(from the heart，from the bottom of one’s heart or essentially)。by heart 的意思是“背誦”、“熟記”(by rote;to learn so well that one can remember it perfectly)。請看下面例句：

That socialite is a rascal at heart.

那個知名人士實(shí)質(zhì)上是個壞蛋。

A councillor should have the collective interest of society at heart.

議員應(yīng)當(dāng)關(guān)心大眾的利益。

王先生看來嚴(yán)肅，但買質(zhì)上他很仁慈。

I know this poem by heart.

我熟讀/我能背誦這首詩。

I don’t see the point of learning by heart all the dates in the history book!

我真不明白為什么要把歷史書里所有的日期都要記下來!

in one’s heart of hearts 在內(nèi)心深處

take something to heart 認(rèn)真考慮/關(guān)注某事

set one’s heart on something 決心做/得到某事/物
