My brother and I gave our 92—year—old mother a cordless portable phone for her birthday.Soon thereafter,we began to get an unusual number of casual long—distance calls from our ordinarily frugal mom. When we asked her about it,she replied,"Why not?It doesn't cost a penny.The phone's not attached to anything." 我和我哥哥送给我92岁高龄的母亲一台无绳移动电话机（手机）作为生日礼物。之后不久，我们就从向来很节俭的母亲那里接到大量随意打来的长途电话。我们问她何故，她回答说：“为什么不打？它分文不花，那电话跟什么都不连着。”
