中考英語(yǔ)知識(shí)點(diǎn):不定冠詞的區(qū)別和用法
1.不定冠詞a 和an的用法區(qū)別:a 用在單詞發(fā)輔音開(kāi)首的單詞前,an用在單詞發(fā)元音開(kāi)首的單詞前。如:
a book, a desk, a pen, a doctor, a house
an enemy, an accident, an animal, an egg
但注意:an hour, a useful tool
2.泛指某人或某事物
An old man is sitting on the chair.
3.表示one 或every,但概念上沒(méi)有它們那樣強(qiáng)烈。當(dāng)表示one的意思時(shí),一般不用two, three等相對(duì)比。如:
Every elephant has a long nose.
Take this medicine three times a day.
4.用于某些固定詞組中。
a few, a bit, a lot of, in a hurry, at a time, all of a sudden, many a, a little, a couple of, as a matter of fact, in a word, have a good time, do sb. a favor, pay a visit to, in a way, have a word with, make a living, take a pride in, take a walk, a great deal of, catch a cold,
