AHey, how come you've never told me you have a cute sister…(嘿!你为什么从来没告诉我你有一个这么漂亮可爱的妹妹?)
BWhat are you trying to say?(你想说什么呢?)
AWell, you can hook me up maybe?(嗯……也许你可帮我介绍一下?)
BNo way.(休想)
“How come﹖”是口语上经常被用来代替“why”的字。但是两者用法不同。用“how come”时句子的构造很接近中文如“How come you didn't call me last night?”你为什么昨晚没打电话给我呢?这句话如果换成用“why”就须要用一般的问句形式“Why didn't you call me last night?”。
