In for a penny, in for a pound
The pound here is the British pound sterling. A penny is 1/100 of a pound. This old saying tells us that if we decide to do something,we shouldcommitourselves to it boldly and completely.
英镑是英国钱币. 一英镑有一百便士. "In for a penny, in for a pound" 是一句谚语, 告诉我们, 既然决定了要做某事情, 就要全心全意的投入, 不论代价地做好它, 正所谓 "一不做, 二不休".
