高中英语冠词的知识1
a 与 an 的用法区别
1.基本区别:原则上说,a用于辅音前;an用于元音前。辅音前用a的例子如: a book, a student, a school, a house,a magazine 等;元音前用an的例子如: an egg, an apple, an object, an idea, an ugly thing等。
2.易错说明:hour, honest, honor等单词的拼写虽然以辅音字母h开头,但其读音却以元音开头,因此,前面要用an。反过来,有些单词虽然以元音字母开头,但其读音却以辅音开头,那么它们的前面应用a而不是an,这些词常见的有useful,university, usual, European, united, one-eyed, one-way 等。
此外,对于数字、字母以及由单词首字母构成的缩略词,其前到底是用a还是an,也需根据读音来确定,如下:
He has an 11-year-old daughter.
Our daughter sent us an SOS for some more money.
冠词在句中的位置
1. 通常位置:一般说来冠词放在单数可数名词之前(如 a man / the man),如果名词有其他定语,不定冠词应放在定语之前(如a goodman / the good man)。
2. 特殊位置:在下面情况中,冠词的位置比较特殊,需要注意。
① 单数可数名词被 such, many, half, what等修饰时,不定冠词应置于其后,这个大家看例子就很容易明白,而且平时基本不会出错。
He arrived half an hour ago.
He couldn’t afford to pay such a price.
② 单数可数名词前作定语的形容词被 as, so, how, too 修饰时,通常采用 “as / so / how / too + 形容词 + a/ an + 名词”这样的词序。
He didn’t know how great a mistake he had made.
It is too difficult a job for me to finish in so short a time.
③ 当定冠词与 all, both, half 表倍数的 double, twice, three times等分数词等一起修饰名词时,定冠词应放在它们之后。
Turn off all the lights before you go to bed.
Everything was almost double the normal price.
