冠词

(一) 知识概要

冠词在英语中只有3个词,分为两类:不定冠词a与an,定冠词the。a用在以辅音开始的单数名词前,an用于以元音开始的单词前。不定冠词用来表示一类事物中泛指的某一事物,而定冠词则用于特指的某一个或某些事物,可用于不可数名词、可数名词单数及可数名词复数前。

(二) 正误辨析

[误]This building is an university.

[正]This building is a university.

[析]a 用于以辅音音素开始的单词前,而an用于以元音音素开始的单词前,而不是元音字母开头的单词前。university的第一个音素是[j],所以 用a而不要用an。又如:There is a “n” in the word.是错句,应为:There is an “n”in the word.因字母n的发音的第一个音素是元音。要注意的还有hour因其第一个字母h不发音,所以应该用an hour。例如:

I need an hour to finish the work.

It is a useful dictionary.

It is a European country.

I bought a used car.

[误]I need a umbrella because it looks like raining.

[正]I need an umbrella because it looks like raining.
