2019年高考一輪復習英語知識點：冠詞與數(shù)詞

　　冠詞與數(shù)詞

　　冠詞本身不能單獨使用，也沒有詞義，它用在名詞的前面，幫助指明名詞的含義。英語中的冠詞題型基本分為有三種，一種是定冠詞(指定，特指，有限定條件或者范圍)，另一種是不定冠詞（沒有指定，不是特指，泛指，一般為同類），還有一種是零冠詞(即不使用冠詞，常常放在不可數(shù)名詞中物質(zhì)名詞和抽象名詞的前面)。

　　2.1 不定冠詞的用法

　　不定冠詞a （an）與數(shù)詞one 同源，是"一（個）"的意思。a用于輔音音素前，一般讀作[e]，而an則用于元音音素前，一般讀做[en]。 并非是很多同學誤解的把an放在a、e、i、o、u五個元音字母前就可以了。

　　1 表示"一個"，意為one；指某人或某物，意為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"一個"。                 There is a bottle on the table. The bottle is empty.

　　3表示非特指的任何"一個"，代表同類事物中的"一個"。 A camel is bigger than a horse.

　　4 代表一類人或物。

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

　　5用在表示時間、速度和價格等名詞前，表示"每一",相當于介詞，per的用法。twice a day, 80 km an hour

　　6用在序數(shù)詞前，表示"再一、又一"，還沒進行過/用過/來過/吃過a second time再一次(言外之意指第二次)

　　7組成詞組或成語，習慣用不定冠詞的短語：

　　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.

　　B. the, /

　　8用在某些物質(zhì)名詞和抽象名詞(不可數(shù)名詞)前 ，即不可數(shù)名詞可數(shù)化
