英語(yǔ)中有兩種冠詞:定冠詞和不定冠詞，三種形式:the和a,an。冠詞雖小，但用起來(lái)很容易出毛病，因此要特別注意。

不定冠詞

(1)不定冠詞a和an的區(qū)別是:a用在以輔音開始的單詞前面，an用在以元音開始的單詞前面，如:

an island, an owl, an effective method, an old man, a fierce tiger, a university, etc.

注意要以單詞發(fā)音的第一個(gè)音素為準(zhǔn)，不要以拼寫的第一個(gè)字母為依據(jù)，這就是為什么像university, unique, unified這些詞，其前面用a而不用an的原因所在。

(2)不定冠詞一個(gè)基本意義就是。ne，因此，很顯然，它不能和復(fù)數(shù)名詞一起用。例如:

(誤)An ears is an organ for listening.

(正)An ear is an organ for listening.

(3)不定冠詞可用在可數(shù)名詞的單數(shù)形式前表示類屬，其意義相當(dāng)于可數(shù)名詞的單數(shù)形式前用定冠詞the或可數(shù)名詞的復(fù)數(shù)形式前不用冠詞表示的類屬。因此，以下三個(gè)句子意義相同:

A tiger is a wild animal.

The tiger is a wild animal.

Tigers are wild animals.

它們都解釋“老虎是一種野生動(dòng)物”。如果說(shuō)成Tiger is a wild animal.那就錯(cuò)了。實(shí)際上，凡見到可數(shù)名詞單數(shù)形式前沒有冠詞的，都值得考慮一下，這種情況大多是錯(cuò)的。

(誤)From then on, we've kept in touch with another through e-mail.

(正)From then on, we've kept in touch with another through e-mails.

(4)不可數(shù)名詞前不可以用不定冠詞，這樣的名詞包括抽象名詞、物質(zhì)名詞和一部分集合名詞

(誤)You can get a information from newspaper and the Internet.

(正)You can get information from newspaper and the Internet.

(正)You can get a piece of information from newspaper and the Internet.

(誤)I'd like to share my favourite fruits with you.

(正)I'd like to share my favourite fruit with you.

(誤)Paper is made from a bamboo.

(正)Paper is made from bamboo.

定冠詞

定冠詞，顧名思義，是用來(lái)指特定的人或物的，這是它的基本的用法。定冠詞的用法。

(1)肯定用定冠詞情況:①上文中已經(jīng)講到過(guò)的;②后面有限定性的修飾語(yǔ)的;③說(shuō)話雙方所共知的;④世上與眾不同的。如:

Cut up a tomato, and put the tomato on the bread. ( tomato是上文中提到過(guò)的)

The singer in that room was given a warm welcome by his fans. ( singer后面有in thatroom的限制)

Please fill in the form and sign it. ( form是雙方所共知的)

Which is the biggest, the sun, the moon or the earth? ( sun, moon, earth都是世界上罕有的的)

(2)定冠詞也可以用在單數(shù)可數(shù)名詞前表示類屬，如前面舉過(guò)的例子:

The tiger is a wild animal.

(3)形容詞的高級(jí)前要用定冠詞，如:

No matter how busy our parents are, they should make the best use of their time to stay withtheir children.

Television is the most effective tool to inform children of the latest news and scientific development over the world.

不用定冠詞的情況。

(1)不要看到most，就以為它前面非得有個(gè)the不可，most有別的用法。如:

(誤)With the emerge of information technology, the knowledge in textbook can't satisfychildren's curiosity any more. The most children need to learn wider knowledge and know moreabout our world.

(正)With the emerge of information technology, the knowledge in textbook can't satisfychildren's curiosity any more. Most children need to learn wider knowledge and know moreabout our world.

(2)序數(shù)詞前要用定冠詞，很多人把這條規(guī)則都記得很牢，但在某些固定的表達(dá)方式中出現(xiàn)的序數(shù)詞前面卻是不用the的，如果把它們看成是錯(cuò)誤，那就上當(dāng)了。如:。

John came out first in the final examination.

You are second to none as far as intelligence is concerned.

(3)大洋、海、河、山脈前都要求有定冠詞，但洲名前卻不能有定冠詞，如:。

the Yangtze River, the Mountain Tai，the Arctic Ocean, the West Lake, North America,Africa。

(4)指演奏一種樂器時(shí)，樂器前必須要有定冠詞;指進(jìn)行一種球類活動(dòng)時(shí)，球類前面不可用定冠詞，如:

My younger brother prefers to play the guitar rather than play basketball.

(5)語(yǔ)言名稱前沒有定冠詞，如:

(誤)The Chinese, the most difficult but beautiful language in the world, is my mother tongue.

(正)Chinese, the most difficult but beautiful language in the world, is my mother tongue.

但如果在Chinese后面加上language，那么前面就要加定冠詞T , the Chinese指的是全體中國(guó)人，如:

All the Chinese love their own language-Chinese most.

類似地，我們說(shuō):

Germany, the Germany language(德語(yǔ))，the German(德國(guó)人);

Japan, the Japan language(日語(yǔ)), the Japanese(日本人);

Korea, the Korea language(韓語(yǔ))，the Korean(韓國(guó)人)

(6)在“……年代”前必須用定冠詞，但在一個(gè)具體的年份前絕不能用定冠詞，如:

(誤)...people who died in 1860's.

(正)...people who died in the 1860's.

(誤)...people who died in the 1860.

(正)...people who died in 1860.

(7)人名前不可用定冠詞，如，不可說(shuō)I'd like to invite the Jack Green，應(yīng)該說(shuō)I'd liketo invite Jack Green.

在人名的所有格前，也不可用定冠詞，如，不可說(shuō)I believe you are a particular friendof the Pickwick's，只可以說(shuō)I believe you are a particular friend of Pickwick's.

(8)定冠詞和指示代詞this, that, these, those在用于特指時(shí)，其性質(zhì)、作用是一樣的，因此不能同時(shí)使用:

(誤)The this man came up to me in the street and started making rude suggestion.

(正)This man came up to me in the street and started making rude suggestion.

以上就是關(guān)于英語(yǔ)定冠詞和不定冠詞的用法，希望可以給大家學(xué)習(xí)帶來(lái)幫助。
