想找冠词的用法高考题

历届高考中冠词的考点
冠词是一种虚词,用在名词或名词词组的前面,表示名词是特指还是泛指。冠词可分为不定冠词和定冠词两种形式。在历届高考英语试题中，冠词虽分值不大，但失分率较高。究其原因，是它的用法复杂。它的用法没有一个很固定的模式，往往是随着语境的变化而变化，可谓变化多端。但这并不意味着它就无规律可循。纵观历届高考试题，冠词的考试点无非以下三种情况：
一、考查定冠词和不定冠词的最基本用法
1、不定冠词修饰可数名词，其意思为“一个”；定冠词既可修饰可数名词，也可修饰不可数名词，往往表特指，其意思相当于“这个”。单数可数名词只要不用在抽象化的语境中，一定要加冠词（或者加不定冠词，或者加定冠词）。可用“一个”或“这个（种）”来区分不定冠词和定冠词。
【考例】1、—-Have you seen_______ pen？I left it here this morning．（NMET97）
—-Is it _______black one？I think I saw it somewhere．
A．a，the B．the，the C．the，a D．a，a
【解析】此题的两个空格处，都应有“一”的意思，“一支笔”，“一支黑色的笔”，所以答案为D。
【考例】2、Have you ever seen _____ as tall as this one?
A. a tree B. such tree C. an tree D. tree
【解析】该题干意思是“你可曾见过跟这棵一样高的树？”，选A。
2、可数名词用于泛指时，单数名词前可加定冠词，也可加不定冠词；复数名词前不加冠词。不可数名词用于泛指时，不加冠词。
【考例】3、Most animals have little connection with _______animals_______ of different kind unless they kill them for food．（NM ET 2000）
A．the，a B．／，a C．the，the D．／，／
【解析】名词的复数常常表示泛指，其前不加冠词；第二个空格填不定冠词，a different kind泛指任何一种不同种类，“animals of a different kind” 表示“（任何）一种不同种类的动物”，故选B。
【考例】4、She is_______ new er to _______chemistry but she has already made some important discoveries．（NM ET 94）
A．the，the B．the，／ C．a，／ D．a，the
【解析】此题中a newer的意思是“一个新来者”，chemistry为不可数名词用于泛指，其前一般不能使用定冠词，故该题选C。
【考例】5、The warmth of_______ sweater will of course be determined by the sort of _______wool used．（NMET 2001）
A．the，the B．the，／ C．／，the D．／，／
【解析】此题的意思是：毛衣的保暖程度当然取决于使用的毛的种类。此题中的“毛衣”和“毛”都是泛指。前者为可数名词，可加定冠词，也可加不定冠词；后者为不可数名词，不能加冠词，故选B。
【考例】6、Many people agree that _______knowledge of English is a must in _______international trade today．（NM ET 96）
A．a，／ B．the，an C．the，the D．／，the
【解析】此题中的trade是表动作之类的名词，为抽象名词，因此不可数。在此题中用做泛指，前面不加冠词，故该题选 A。
3、名词后跟有限制性的定语时，名词前通常加定冠词。
【考例】7、Many people are still in _______ habit of writing silly things in _______public places．（NM ET 93）
A．the，the B／，／ C．the，／ D．／，the
【解析】名词后跟有限制性的定语，名词前通常加定冠词。因habit受of writing silly things所修饰，表示乱写乱画的习惯，所以为特指，故 habit前加定冠词；public places泛指公共场所，而且为复数名词，所以不加冠词，选C。
【考例】8、In Hangzhou Mr Green was so struck by ___ beauty of ___ nature that he stayed for another night. (91上海)
A. /; / B. /; the C. the; / D. the; the
【解析】nature 前不用冠词，of nature 做抽象名词 beauty 的定语，所以其前要用定冠词，故选C。
4、定冠词用在形容词或副词的最高级或序数词前；在姓氏的复数前加定冠词，表示一家人。
【考例】9、 _______ cave that Gee has discovered in his lifetime is near the Alps. （上海 92）
A. The hundredth B. The hundred C. Hundredth D. A hundredth
【考例】10、________ will make a trip around the world during the ing Christmas. （上海 93）

【解析】根据叙述，上三题分别选A，C，C。

It is as pleasant a day as I have ever spent.
So short a time.
Too long a distance.
　c. quite，rather与单数名词连用，冠词放在其后。
但当rather，quite 前仍有形容词，不定冠词放其前后均可。如：quite a lot
　d. 在as，though 引导的让步状语从句中，当标语为形容词修饰的名词时，不定冠词放形容词后：
　 Brave a man though he is，he trembles at the sight of snakes. 他尽管勇敢，可见到蛇还是发抖。
当名词被比较级形容词修饰时，不定冠词通常置于比较级形容词之后。

　 All the students in the class went out.　班里的所有学生都出去了。
冠词的使用错误
大家除了掌握使用冠词的基本规则外，还应不拘泥于规则，注意冠词的活用：
1．表示世界上独一无二的事物的名词前一般加定冠词the; 但如果名词前有修饰语，也可能用不定冠词a,an。
the world, a peaceful world
the moon, a bright moon
2. 表示一日三餐的名词前面一般不用冠词，但前面如果有了定语修饰，也可能用不定冠词a, an。
Have you had supper?
We had a wonderful supper.
3. 表示乐器的名词前一般用定冠词the, 但前面如果出现定语修饰，也可能用不定冠词a, an。

He went to the station in a black car.
5. 表示语言的名词前一般不用冠词，但后面如果出现language一词，前面需加定冠词the。
English=the English language French=the French language
6. turn用作系动词时，后面作表语的单数名词前不用冠词。
He turned writer many years later.(=He became a writer many years later.)a , an , the都是定冠词，需要知道的是5格元音音素（诶，易，艾，哦，又），用法如下：
a 和 an 都是修饰单数的，它们的区别在于冠词后所加的名词（非专有名词）,例如apple要加 an而不是a ，因为apple中打头的字母发“诶”的音，所以要用an .而car则用a，原因与用an的相反，就是开头字母不是元音音素。
the比较特别点，基本都用来表示特指，也用来表示一类
