复合形容词与连字符
当使用两个或更多的词来描述伴随的名词时,所得到的复合形容词(两个或更多个词的组合)经常加上连字符。在某些情况下,不使用连字符作为复合形容词可以极大地改变句子的含义,比如以下情况:
“The airport authorities detained Jacob for not carrying a concealed weapons permit.”
(上句中,我们无法得知Jacob究竟是因为未携带许可还是未被许可而被拘留!)
“The airport authorities detained Jacob for not carrying a concealed-weapons permit.”
(加上连字符后,我们可以清楚地知道,Jacob是因为未携带许可而被拘留! )
