冠词和数词及练习

.本资料来源于七彩教育网第三章 冠词和数词冠词是一种辅助性的词，不可在句中独立担任一个成分。放在名词前，帮助说明名词的含义，使用极为频繁。冠词有不定冠词（a, an）和定冠词（the）两种。a和an的基本含义是“一，一个”，表示泛指，不强调数目，只表示名词不是特定的；the的基本含义是“这个，那个”，表示特指，在可数的单复数名词或不可数名词前面都可以用。冠词本身是虚词，没有意义，同时也没有词义，它用在名词的前面，帮助指明名词的含义数词可分为基数词（Cardinal Numbers）和序数词（Ordinal Numbers）两种。前者表示数量，后者表示顺序。 高考重点要求：一、冠词1、不定冠词、定冠词和零冠词的基本用法2、不定冠词和定冠词的位置3、冠词常见的习惯搭配用法二、数词1、掌握基数词、序数词构成2、掌握基数词、序数词的基本用法3、基数词、序数词在表示倍数、百分数、年、月、日等的基本用法第一节 知识点概述一、冠词（一） 不定冠词不定冠词用a还是an由后面一个词的首音决定。以元音开头的词前用an，以辅音（包括半元音，不是元音字母）开头的词前用a。例如：辅音字母或半元音开头：a tree, a university, a house, a European country, a one-eyed man元音或半元音开头：an apple, an umbrella, an hour, an elephant, an opera值得注意的是：1如果不定冠词后面第一个词以辅音音素开头就用a。例如university, useless, useful, unit, uniform; 以元音音素开头用an .例如:an uncle , an apple 。2如果不定冠词后面第一个词以不发音的h开头，而h后面第一个音的音素是元音因素，就用an。例如hour, honest。3如果不定冠词和名词之间有其他词，不定冠词的形式仍取决于它后面第一个词的语音形式。例如a rich uncle , a beautiful actress。不定冠词的用法如下：1用在单数可数名词前，表示一类人或事物，如：A dictionary is a useful book.An underground train can start and stop quickly.2说明某人或某东西属于哪一类，如： This is a book. He used to be an engineer.3泛指某人或某物，但未具体说明何人、何物，如： A boy is waiting for me.Give me a pen, please.4表示数量，有“一”的意思，如： Behind the house there is a garden. once a week.5用于某些固定词组中，如： a few, a little, a lot of, a number of, just a minute, in a hurry, for a while, for a long time, a cup of, a bottle of, have a rest, have a talk, have a fever, have a good time, have(take) a walk, have a toothache, take a bath, give a lesson（二）定冠词定冠词的用法如下：1指彼此都知道的人或事物，如： Open the door, please.

Hed like to have _ third one because _ second one is rather too small.A. aa B. thethe C. athe D. thea答案为C。【解析】 注意序数词前面的冠词的用法：当序数词表示顺序时用定冠词the；表示再来一次使用不定冠词a (an)。从句子的意思可知，third one表示再吃一个，所以填a；second one表示所吃的第二个，所以填the。这句话的意思是：蛋糕很好吃。他想再吃一个，因为他吃的第二个太小了。例5、A bullet hit the soldier and he was wounded in _leg.A. a B. one C. the D. his答案为C。【解析】 伤及某人某部位或拍、打、拉某人某部位要用句式wound/bit/beat/pat/take+sb+介词+the+部分。译文：子弹击中了战士，他的腿受了伤。例6、_people in the world are sending information by email every day.A.

Two fifth.is B. Two fifth.are C. Two fifths.is D. Two fifths.are答案为C。【解析】 分数的分子用基数词，分母用序数词表示。如果分子大于1，序数词后加-s。分数和百分比作主语时，谓语动词的形式取决于分数和百分数后的名词。句子中的主语land是单数，所以谓语动词要用is covered。 例8、Paper produced every year is _ the worlds production of vehicles. A. the three times weight of B. three times the weight ofC. as three times heavy as D. three times as heavier as 答案为B。【解析】 表示倍数的词数放在the weight of前，意思是“重量的几倍”。 例9、 An accident happened at_ crossroads a few metres away from_ bank.A. aa B. /a C. /the D. the/答案为A。【解析】 at a crossroads表示“在十字路口”，crossroads“十字路口”是复数形式单数用法；bank是可数名词，不能单独使用(要加冠词或复数)，又非特指，不能用the。此处是泛指，前面要用不定冠词a。例10、Smith _ me to buy several _ eggs for the dinnerA、askeddozen B、suggesteddozens of C、haddozen D、persuadeddozens of答案为A。【解析】 “dozen +复数名词”前除了用具体数词修饰外，还可以用several, many 修饰，如several dozen people, many dozen students等，dozen 不加s。第三节 巩固练习1.
