a和one的区别是什么？
展开全部 a和one的区别1. 尽管a和one这两个在意义上有些相似，但他们几乎不能互换使用。
2. 在连续记数时，习惯上用one，不用a3. 在名词前使用one 往往表示数量上的对比。
4.用在某些固定的词组中。
如： in a hurry, in a word one by one, one day另：不定式冠词a与one的用法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（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） 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。
We all march forward to one objective,i.e.,communism. 望采纳！
try to guess a word's meaning by reading the sentences before and ...
Try to guess a word's meaning by reading the sentences before and after it .翻译：根据上下文推测单词的意思。
word's——单词的意思，不是简写。
's的用法1. 名词所有格。
's加在单数名词或不以s结尾的可数名词复数后面，构成所有格，也可以加在one, another, other, neither等代名词之后构成所有格。
以s结尾的复数名词只需加“'”，即构成所有格。
例：the fox's tail狐狸的尾巴（可数名词单数's+名词）Hermingway's novel海明威的小说（人名's+名词）the boys' teahcer男孩的教师（以s结尾的可数名词复数'+名词）children's bedroom孩子的卧室（不以s结尾的可数名词复数's+名词）one's self-esteem人的自尊心2. is\has\does的缩写，多用于口语中。
例如：She's beautiful.她很漂亮。
（'s是is的缩写）Mary's going to look after you. 玛丽会照顾你的。
（'s是is的缩写）be going to do 计划做某事。
It's got to be done. 这件事非做不可。
（'s是has的缩写）What's he want？他想要什么？（'s是does的缩写）这个缩写是根据后面跟着的词判断。
初学者如果不能直接判断，可以试着把句子还原。
比如What's he want? = What does he want?请记住，一个句子只能有一个动词（原形、过去式、过去分词）。
若's 后面有动词原形，则为does的缩写；'s后面是动词的过去分词，则必定为has的缩写；若's后无动词，则为is的缩写。
3. 与let连用，为us的缩写。
例如：Let's go.我们走吧。
4. 4用于构成店名、家庭、特定地点等。
例如：The butcher's肉店（从业人员+'s）at Mary's在玛丽家里（人名+'s） St. Paul's圣保罗教堂（这种用法多数是约定俗成的，多用于博物馆、教堂等）s'和's的区别加s' 是指名词的复数的所有格加‘s 是指名词单数的所有格例：老师的 teacher's老师们的 teachers'参考资料百度文库：https://wenku.baidu.com/view/e28419079b6648d7c1c746b2.html
