a
冠词
一(个); 每一(个); 任一(个)
1. 基本词义:用于单数可数名词前,表示未曾提及的一(个、件……)人(或物……)
2. 辨析:
a与an
- 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;
- 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。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。a 也有“任何一个”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。I wanted to read a book,I did not care whether it was a history,a novel,or a biography. - a 与 few 搭配使用时,few 是“很少”,有“几乎没有”的意思。a few 是“若干”,有“颇有几个”的意思。注意,only a few 却等于 few,也是“很少”的意思。
a与one
含义不同:one释义:一;单独一个,仅仅一个。
a 释义:用于可数名词或单数名词前,表示未曾提到的一人、事;用于前有形容词或后. 有短语的不可数名词前;任何一;每一。
用法不同: one用法:示”一个”,意为one; 指某人或某物;代表-类人或事务;用在可数名词的单数形式前表示泛指。
例句: He’s the one person I can trust. 他是我唯一可以信赖的人。
a用法:通常来说,a是用在以辅音开首的词前面,可数名词前面用a不可数名词前面不可用a,如可以说a healthy boy,却不可以说a health。在特定情况下,a可以用在复数形式前面。
例句:Their new car’s a BMW.
他们的新轿车是辆宝马。
侧重点不同:
one是明确的数字。
a是范围概念,常被叫做不定冠词。
a / E; strong form ei / (also an / En; strong form An / )indefinite article
a 用于辅音前,an 用于元音前。在 FM、UN 等缩略语前,用 a 还是 an,需视首字母如何发音而定。如 F 是辅音字母,但其发音以 e 开头,故应说:an FM radio。U 是元音字母,但其发音以 j 音开头,故应说:a UN declaration。
