冠词是一种虚词，这词本身没有实在的意义，不能独立使用，不能独立的承担句子的成分，只能置于名词前，用来帮助说明词的含义，使词的含义更加完整。
2. 分类：不定冠词a/an 定冠词the (零冠词)二. 不定冠词a/an1. a/an的区分：
a用于辅音音素前，an用于原音音素前，不仅仅是五个元音字母A E I O U。 例如：an hour['au?]/ an hones man/
a university/ a united[ju:'naitid] country/ a European country

5. 用于习惯用语中：
感冒have a cold 玩的很高兴have a
good time 突然 all of a sudden 三.定冠词1. 定冠词“the”和指示代词this/that同源，有“那，这个”的意思，但较弱，和名词连用来表示某个或某些特定的人或物。
2. 在哪些情况下使用定冠词“the"：
(1) 表示某个或某些特定的人或物：
例:汤姆是我们班的班长。（不是别的班的）
Tom is the moniter of our class.
(2) 特指双方都明白的人或物：
例:我很冷，请把门关了。(双方都知道是
哪个门）I am cold,would you please
close the door.

第三the third
他是我们班最高。
He is the tallest in our class.6. 用在表示乐器的名词前：
例.他会弹钢琴/拉小提琴/弹吉他......

这里要和球类，棋牌类区别开来：
例如:打篮球/踢足球/下棋......
play basketball/football/chess......
7.用在姓氏的复数名词前，表示一家人：

(2)名词已经有了物主代词，指示代词，不定代词，名词所有格：

总结 总的，从原则上来讲，单数可数名词除了在惯用词组中以外，必须有冠词a an the. 复数名词和不可数名词用于泛指时可以不用冠词，用于特指时就必须用定冠词the。
同学们在使用中,要看清楚名词的数，语
句要表达的意思，以及多积累英
语中的惯 用语。
