2019高考英语必备知识点：不定冠词的用法

　　不定冠词a (an)与数词one 同源，是"一(个)"的意思。a用于辅音音素前，一般读作[e]，而an则用于元音音素前，一般读做[en]。并非是很多同学误解的把an放在a、e、i、o、u五个元音字母前就可以了。

　　1 表示"一个"，意为one;指某人或某物，意为a certain。

　　e.g. There's a policeman at the door. Pass me an apple, please. A Mr. Ling is waiting for you. 有位凌先生在等你

　　2初次提起某人或某物，表示"一个"。 There is a bottle on the table. The bottle is empty.

　　3表示非特指的任何"一个"，代表同类事物中的"一个"。 A camel is bigger than a horse.

　　4 代表一类人或物。

　　e.g. A knife is a tool for cutting with. 刀是切割的工具。 Mr. Smith is an engineer. 史密斯先生是工程师。

　　5用在表示时间、速度和价格等名词前，表示"每一",相当于介词，per的用法。twice a day, 80 km an hour

　　6用在序数词前，表示"再一、又一"，还没进行过/用过/来过/吃过a second time再一次(言外之意指第二次)

　　7组成词组或成语，习惯用不定冠词的短语：

　　e.g. a piece of, a cup/glass of, a pair of, a loaf of, a pile of, a kind/type/sort of, a (large) number of, a lot (of), a couple of, a bit/little/few,

　　a good/great many, many a / as a rule / as a result (of) / a great deal of, as a matter of fact, in a hurry / in a minute / in a word / in a short while(soon after/shortly after) / after a while / a moment later, quite a few/lot

　　as a result, catch/have a cold/fever /headache, have a chance; have/take a bath, have/take a break, have/take a breath; have/take a rest, have/take a swim, have a try/go, have a walk, go for a walk, pay a visit to; have a good/great time, have/live/lead a happy life,

　　Everything comes with ________ price; there is no such ________ thing as free lunch in the world.

　　A. a, a

　　B. the, /

　　C. the, a
