fourpenny

I hit her such a fourpenny one that I sent her flying.

我一拳把她打飞。

but before the week was out he was sure to think better of it, bring me my fourpenny piece, and repeat his orders to look out for 'the seafaring man with one leg.

但不出一星，他准又会改变主意，把那四便士银币给我，重新叮嘱我，要我留神那“独腿水手”。

One day,he took me aside and promised me a sliver fourpenny on the first of every month if I would keep my eye open for a sailor with one leg and let him know the moment he appeared.

有一天他把我拉到一边，向我保证每月初给我四便士，如果我能留心注意一有一条腿的水手，并且在他（水手）出现的那一刻告诉他。
