not...but...如何加从句
not...but...是很有用连接并列结构的短语,意思为“不是...而是...".
加从句也和加其他对象一样,将其放在not...but...的省略号所在位置即可.如:
It is not who you are or what background you have but what you can do for others that is of great value.
再问: 如果加的是陈述句呢?要加引导词that吗?
再答: 所给的例句就是陈述句。再如: They want not your pity but your help. He helped not me but you. Ask not what your country can do for you;ask what you can do for your country. You should pay attention not to what they say but to what they do. but 还可以被直接看作是连接词: No man is too old but he may learn.【but=but that引出的从句有结果含义】【其中的that经常省略】 It never rains but it pours.【but=but that】 There is no rule but has exception.【关系代词】 Not a man but has tears in his eyes.【关系代词】
再问: that 可以省略吗?在什么情况下不能省略呢?
再答: 问得好!省略,概括来讲,都有统一的条件,即【适用文体的限制:口语和非正式文体才经常用省略形式;二正式文体和正式交际场合都不用省略,以示庄重】
