二、 冠詞
(一) 知識概要
冠詞在英語中只有3個詞,分為兩類:不定冠詞a與an,定冠詞the。 a用在以輔音開始的單數名詞前,an用于以元音開始的單詞前。不定冠詞用來表示一類事物中泛指的某一事物,而定冠詞則用于特指的某一個或某些事物,可用于不可數名詞、可數名詞單數及可數名詞復數前。
(二) 正誤辨析
[誤]this building is an university.
[正]this building is a university.
[析]a用于以輔音音素開始的單詞前,而an用于以元音音素開始的單詞前,而不是元音字母開頭的單詞前。university的第一個音素是[j],所以用a而不要用an。又如:there is a "n" in the word.是錯句,應為:there is an "n"in the word.因字母n的發(fā)音的第一個音素是元音。要注意的還有hour因其第一個字母h不發(fā)音,所以應該用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.
[誤]i need a umbrella because it looks like raining.
[正]i need an umbrella because it looks like raining.
[析]因umbrella的第一個音素是元音,所以應用an.常用的情況有:an old man, an english teacher, an elephant, an idea, an hour ago, an honest boy…。
[誤]"can you help me" "sorry, i'm in hurry."
[正]"can you help me" "sorry. i'm in a hurry."
[析]不定冠詞的主要用法如下:
1. 用來表示一類人或事物,如:she is a teacher.
2. 指某一類人或事物中的一個,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. 相當于"one"的概念,如:i just bought a new dictionary.
5. 其主要的難點是用在固定詞組中:
如:have a walk/a rest /a look
又如:in a hurry 匆匆忙忙
make a face 作鬼臉
do somebody a favour 幫某人忙
a number of =many
又如:have a good time (玩得好)
have a cold (感冒)
have a headache (頭痛)
have a break=have a rest
[誤]i bought the dictionary yesterday. a dictionary is very good.
[正]i bought a dictionary yesterday. the dictionary is very good.
