at heart：内心里，实质上，本质上

e.g. Her modesty is all put on; at heart she is very vain.

e.g. With all the outward severity he is kind at heart.

e.g. His manners are rough, but he is a kind man at heart.

他虽然举止粗鲁，但心地善良。

e.g. She may appear severe toward her children but she is a fond mother at heart.

她表面上对孩子的态度很严厉，实际上是一位慈祥的妈妈。

at least：至少，最起码

e.g. These, at least, were their professed reasons for pulling out of the deal.

至少这些是他们自称退出这宗交易的理由。

e.g. At least Jeremy had the good form to go back and apologize.

杰里米回去道歉至少是有礼貌的举动。

2. So it was perfectly reasonable to see the marriage plot as a way of binding up the unhealed wounds of the reformation, but the Queen wasn't fooled not for a moment.

bind up

彼得希望通过安慰能使玛丽不再伤心。

e.g. He whipped out a handkerchief to bind up his injured finger.
