a与one的用法区别

不定式冠词a与one的用法_高考指导,高考,基础教育1.作“一(个)”讲,不定冠词a所表达的“数量”这一概念,远不如one这个数词来得明确和恰当(注:这样使用,a或an就是one的弱势形式.参见词目1、3和4).
例如:I want to live a hundred years.—M.Swan.我想要活100岁.(是一种“姑妄言之”的说法,所以要用a,不用one)
The journey took exactly one hundred days.—M.Swan.这次旅行整整历时100天.(这里说的是一个事实,所以要用one,不用a,并可加饰exactly这样一个副词)
比较:Give me an apple,will you?给我一只苹果,好吗?(是与some或any相对而言)
Give me one apple,will you?给我一只苹果,好吗?(是与two、three…相对而言)
We saw a panda in the Zoo this morning.今天早晨我们在动物园里看见一头熊猫.(是回答“What did you see in the Zoo this morning?”的提问,所以强调的是panda)
We saw one panda in the Zoo this morning.今天早晨我们在动物园里看见一头熊猫.(是回答“How many pandasdid you see in the Zoo this morning?”的提问,所以强调的是one)
“Can a boy carry it?”—“No,perhaps a man can.”“孩子拿 得动吗?”——“不,也许成年人拿得动.”(a不一定要跟two、three…相递增)
“Can one boy carry it?”—“No,perhaps two boys can.”“一 个孩子拿得动吗?”——“不,也许两个孩子拿得动.”(one 必须跟two、three…相递增)
It seems only a day or two since we first came.我们初到这里,好像只过了一、两天.(也许是一天或一天多或甚至两天)
It seems only one or two days since we first came.我们初到这里,好像只过了一天或两天.(不是一天就是两天)
It has rained for more than a week.雨已下了一星期多了(也许是八、九天).
It has rained for more than one week.雨已下了不止一星期了.(也许是两星期)
2.作“同一”或“同样”讲,a所表达的“一体”这一概念,也不如one来得明快和响亮.
例如:In the old society,two of a trade could never agree.在旧社会同行是怨家.
