前面加冠词a，the，例如：
1、Ben has also been in the wars. He is still in plaster after breaking a leg.本也受了伤。他摔断了一条腿，现在还打着石膏。
2、He broke a leg and was~ d for a month.他跌断了一条腿，要留医一个月。
3、A man was shot in the leg.一个人被射中腿部。
4、These jeans are too long in the leg.这条牛仔裤的裤腿太长。
英语中的习惯用法。只能说three-legged/three-leg table，500-word composition不能说500-worded composition。
