1、不定冠词的基本用法:不定冠词的主要功用为“非特指”、“泛指”。即指某类人或物的任何一个或某个。它有意义相同的两个形式：a 和an,a 用于辅音前，读作;an 则用于元音前，读作.1)表示“一个”这个数量，意思和“one”相当。如：Rome was not built in a day.罗马不是一天建成的。（谚语）Id like an apple.我想要一个苹果。A stitch in time saves nine.及时（缝）一针顶十针。（谚语）这种用法在某些表示重量、长度、时间等的词中特别普遍。如：a pair of socks 一双袜子 a hundred 一百 two yuan a me
2、tre 两元一米 at a glance 一瞥 eight hours a day 一天八小时。twice a week 一周两次 a cup of coffee 一杯咖啡 a handful of rice 一把米 at a blow 一下子 at a stretch 一鼓作气 one at a time 每次一个 in a word 一言以蔽之 当用复数来表示时,则用some或any.如:Id like some apples.I dont want any apples.因此,当不定冠词强调数量概念时,some 和any常被看作是a/an的复数形式.2)“任何一个,”如:Pass me
3、a pencil,please.请递一支铅笔给我.(任何一支铅笔)3)“某一个”如:A man called you just now.一个人刚刚给你打电话.She has just graduated from a Beijing university.他刚从北京一所大学毕业.4)“一类”.此用法同定冠词表示类别的用法是一致的.A child needs love.儿童需要爱.The dog is mans best friend.狗是人类最好的朋友.另：有时序数词前也用不定冠词a或an，其 汉译为“再一次（一个）”。如：I lost the first two games,but I wa
4、nt to try a third.前两盘我输了，但我想再试一盘。5)a/an与one的区别:不定冠词a/an强调数量概念时相当于one,二者可互相替换使用.eg:a/one hundred a/one third a/one dollar a/one metre 但是,a/an 与one之间也有区别,在许多情况下二者不能相互替换使用:a)one不能指“任何一个”.如:A knife is no good,you need a screwdriver to do the job properly.一把刀不行,你干这活需要一把螺丝刀合适.b)当强调“只有一个时,”只能用one.如:There i
5、s only one apple left,there were plenty in the morning.c)one 经常与day,week,month,year,summer,winter 等连用,用来讲故事或描述过去发生的事情.如:One day,many years later,I found out what had really happened.许多年后的一天,我弄明白了真正发生的什么事情.One winter the snow fell early.一年冬天雪下得早.另外,one day 也可以表示“将来某一天”.“总有一天.”如:One day youll be sorry
6、 you treated him so badly.总有一天,你会后悔,你对待他是那样恶劣.d)one 可以与another/others 连用,强调与“另一个(些)”“相对的一个.”如:One boy wanted to read,another/others wanted to watch TV.一个男孩想读书,另一个/另一些想看电视.Fill in the blanks with a,an or the(1)_ baby _ desk _bird _village _knife _useful book _university _zoo _driver(2)_orange _ear _
