二、 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的发音的个音素是元音。要注意的还有hour因其个字母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.

[析]因umbrella的个音素是元音,所以应用an.常用的情况有:an old man, an English teacher, an elephant, an idea, an hour ago, an honest boy…。

[误]“Can you help me” “Sorry, I'm in hurry.”

[正]“Can you help me” “Sorry. I'm in a hurry.”

[析]不定冠词的主要用法如下:

1. 用来表示一类人或事物,如:She is a teacher.

2. 指某一类人或事物中的一个,如:An elephant is bigger than a horse.

3. 泛指某一人或事物,如:A man is waiting for you at the school gate.

4. 相当于“one”的概念,如:I just bought a new dictionary.

5. 其主要的难点是用在固定词组中:

如:have a walk/a rest /a look

又如:in a hurry 匆匆忙忙

make a face 作鬼脸

do somebody a favour 帮某人忙

a number of =many

又如:have a good time (玩得好)

have a cold (感冒)

have a headache (头痛)

have a break=have a rest

[误]I bought the dictionary yesterday. A dictionary is very good.

[正]I bought a dictionary yesterday. The dictionary is very good.

[析]在文章中次提到某物时用不定冠词,而第二次提到时用定冠词。

[误]Please turn off lights before you leave.

[正]Please turn off the lights before you leave.

[析]虽然是次提到某物但说话双方均知其所指,也应用定冠词。

[误]There are nine planets around a sun.

[正]There are nine planets around the sun.
