我知道他穿着破烂的牛仔裤看上去有些浑金璞玉的样子,但清楚他是为当地的慈善事业做了许多有益的工作。 I know he looks a bit of a rough diamond in his tattered jeans, but apparently he does a lot of good work for local charities.
他这个人做事一不做二不休--向慈善事业捐款不捐则已,一捐就是一大笔。 He's not a man who does things by halves -- either he donates a huge sum to a charity or he gives nothing.
