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.
[析]因umbrella的第一个音素是元音,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.
