You must form the most tremendous bonds, even with a servant.

即便他是下人，是难之交。

Of Dinah's affectionate entreaty to think of her as a friend in trouble?

黛娜深情恳求她视为难之交？

I shall look after my friend in need.

来照看难之交。

Now, for the first time, she remembered without indifference the affectionate kindness Dinah had shown her, and those words of Dinah in the bed-chamber—that Hetty must think of her as a friend in trouble.

现在，她第一次毫不冷漠地想起了黛娜对她深情款待， 想起了黛娜在卧室里说那些话——赫蒂一定是把她当成了难之交。
