词源考究法
词源同one,inch,unit.
语法分析
1.an和a都是不定冠词,the是定冠词。冠词在语言运用中有很重要的作用,也是学校的重点考点之一。
2.通常来说,a是用在以辅音开首的词前面,an是用在以元音开首的词前面;可数名词前面用a(或an),不可数名词前面不可用a(或an),如可以说a healthy boy,却不可以说a health;
3.在特定情况下,a(或an)可以用在复数形式前面习语中有a few(books),a great many(books)等表示方法。在表示时间或款项的短语前面,如a further five minutes。在若干在形式上是复数而在意思上是单数的单词前面,如a barracks,a links。
4.在美国口语中,如a good ways,a long ways;a(或an)有时有“一个而不是那所要的一个”的意思。
I got a letter indeed,but it was from a friend.事实上,我收到了一封信,但只是一个朋友的来信。
5.a也有“任何一个”的意思。I wanted to read a book,I did not care whether it was a history,a novel,or a biography.
6.a与few搭配使用时,few是“很少”,有“几乎没有”的意思。而a few是“若干”,“有几个”的意思。
注意:only a few却等于few,也是“很少”的意思。
