在英语里可以用a dab hand来形容某人是做某事的内行、老手。这个说法后常跟介词at来表示某人是哪个行当的能手。
　　例句：
　　1.I'm going to ask my brother to help put up the shelves. He's a dab hand at DIY.
　　2.I'm not boasting, but I'm a dab hand in the kitchen. What would you like to eat?
　　注意：
　　To dab的意思是轻轻地触摸、涂抹某物或擦拭液体。
　　例句：
　　1.If you spill wine on the carpet, just dab it gently with a damp cloth. Don't rub it in.
　　2.Before she goes out my girlfriend always dabs some perfume behind her ears.
