零冠词的记忆法

冠词在英文中属于虚词,在句子里主要是对名词起限定作用。这类词的数量很小,但是其活动性却很大,很大。在英文中,a / an并不等于one 。
例:He only has one dictionary.他只有一本词典。( 正确 )
He only has a dictionary.他只有一本词典。( 错误 )
One minute is enough for me to do it . 我做这件事一分钟足够了。(正确 )
A minute is enough for me to do it . 我做这件事一分钟足够了( 错误 )
1) 不定冠词在句子中最大的语法功能是:用在可数名词的单数形式前表示泛指--表明一类人或事物区别于它类。
例:I am a Chinese. 我是(一个)中国人。
This is a book. 这是(一本)书。

2)为了读音的方便,在以元音音素开头的可数
名词的单数名词前用an而不用a。当我们使用an时,条件有三:①这个名词的读音必须是以元音音素开头--即它的 音标的第一个音素是元音,而不是说它是以元音字母开头。②它必须是个可数名词。③它还必须是个单数名词。我们常常见到这类用法:
a university 一所大学 an hour 一个小时
an orange 一只桔子 an engineer 一位工程师
an ordinary man一个普通人
an honest person一位诚实的人

3)定冠词在句子中,既可以用于可数名词前,也可以用于不可数名词前;既用在可数名词的单数形式前,也用在可数名词的复数形式前。从表达意义上讲,它既可表达this, that之意义,也可表达these, those之意义。例:
This is the very ink I'm going to buy. 这正是我要买的那种墨水。
The words on the blackboard are to be learned next time. 黑板上的这些单字是下次课要学的。

4) 定冠词在句子中最大的语法功能是对名词加以限定,使其成为具有某种意
义的特定名词。这种"特定意义"通过比较是不难看出的。例:
Here are the records you want. 这些是你要的唱片。
I bought some records yesterday. 昨天我买了几张唱片。
Have you decided on the prices yet? 价格你们确定了吗?
了解了上述关于冠词的几个基本概念以后,我们就可以来进一步讨论冠词基本用法的具体情况了。

不定冠词基本用法

1)用于泛指人或者事
She wanted to rent an apartment near the campus. .她想在学校附近租一套房子。
Before she left for London, Sally sent me a picture of herself. 萨莉动身去伦敦前送给我一张她的照片。
A grammar book is necessary to a language learner. 对语言学习者来说,语法书是很必要的。
A teacher likes putting a watch on his / her desk while lecturing .老师讲课时总爱将手表放在讲台上。

2) 用于某些词组中。这种用法是约定束成的,我们只有遵从而无旁的选择。例如:
have a rest(休息) have a look(瞧瞧) have a good time(过得开心)
take a shower(淋浴) take a break(休息) take a bath(洗澡)
get a cold(患感冒) get a fever(发烧) develop into a habit (养成习惯)
make a living(谋生) make a guess at(猜测) make a difference between(区分)
in a moment(过一会儿) in a sense(在某种意义上) in a way(在某种程度上)
once in a while(间或) have an advantage over(优于)
have an edge(略胜过)as a result(因此)as a rule(通常)as a whole(总体上说)

a/an 不定冠词和 the 定冠词的用法

1. 基本文法说明
英文中的冠词是用来指称陪伴单数可数名词,也就是当你在句子中提到单个或单件的人事物时,需要在前面加个冠词来表示单“一”的存在。而冠词中又分为「不定冠词」以及「定冠词」两类。顾名思义,「定冠词 the」的使用时机在于你所提到的单数名词是“那一个”“这一个”特别指定的目标物,反之如果没有特定的指称对象就只要用「不定冠词 a/an」就可以了。

2. 错误发生情况及修正练习
仔细看看下列的句子,哪里出了错?又该如何修正?
A. I am not English. I am Chinese.
我不是英国人。我是中国人。
B. Our department needs a secretary and accountant.
我们部门需要一名秘书和一名会计。
C. I am eating an apple pie. An apple pie is still hot.
我正在吃苹果派。这派还正热着呢。

3. 错误修正及解释
正确的句子如下:
A. I am not an English.I am a Chinese.
根本忘记在单数名词前面加冠词
会发生这样的错误通常是因为受到中文习惯的影响,因为在中文的表达里我们并不一定会把“一个”或“一样”等等的量词说出来或写出来,所以在英文表达的时候要特别留意。
B. Our department needs a secretary and an accountant.
有连接词的时候忘记在后面的单数名词加冠词
虽然and 之类的连接词有连接前后两个名词的功用,但是个别的冠词还是不能省哦!
C. I am eating an apple pie. The apple pie is still hot.
搞不清楚定冠词 the 应该用在“那一个”“这一个”特别指定的目标物前面
通常第一次提到一样东西或一个人的时候,我们是在介绍全新或者是听者不知道的人事物,因此不需要特别指定只要用不定冠词 a/an 就可以了。但是当我们在后来的叙述或谈话中再次提到“那”一样东西或“某”个人的时候,就要用到定冠词 the 来表示先前已经提过的单数名词。
