英語學習中,經常涉及到冠詞的用法填空及選擇,之前發布的文章中,已經詳細介紹了定冠詞the的用法(可以翻看作者之前文章)。今天我們詳細介紹不定冠詞a/an的用法。
一、定冠詞的用法:
a 、an與數詞one 同源,是&34;的意思。a用於輔音音素前,而an則用於元音音素前。
詳細用法如下:
(1) 表示某一類人或某事物中的任何一個,經常用在第一次提到某人或某物時,用不定冠詞起介紹作用,表示一個。
I gave him a book yesterday . 我昨天給了他一本書。
I am reading an interesting story .我在讀一則有趣的故事。
(2) 表示人或事物的某一種類, 強調整體, 即以其中的一個代表一類。
A horse is useful to mankind. 馬對人類有用。
(3) 不定冠詞用在事物的&34;前,如時間, 速度, 價格等意義的名詞之前,表示 &34;。
We often go to school twice a day. 我們常常一天兩次去學校。
They send emails to each other three times a month.他們每個月給對方發三次電子郵件。
(4)在特定的短語裡表示特定的含義,與不可數名詞連用
如:have a good time 過得高興
(5) 一日三餐前有修飾語時。
如:-Mum, what should we have for lunch?
-Jiaozi.
-Oh, what a wonderful lunch! I enjoy it very much.
(6)不定冠詞用於某些詞組中。(需熟記於心)
after a while過了一會兒;過一會兒 /make a difference有影響;有所作為
in a hurry 迅速地;匆忙地;急速 / in a word總而言之;簡言之
keep an eye on留意;密切注視 /all of a sudden 突然地;出乎意料地
make a living 謀生;維持生計/ have a cold感冒/have a gift for有······的天賦
as a result 因此;結果/as a matter of fact 事實上/a waste of ...······的浪費
a little / a few / a lot / a type of/ a great many / as a rule通常;照例 /in a minute / in a short while / have a try 試一試
口訣記憶: 泛指用a/ an,單數可數;特指用the,不特不the。
