(三)冠词和数词及练习.pdf

第三章第三章 冠词和数词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（不定冠词（a,ana,an）和定冠词（定冠词（thethe）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（基数词（Cardinal NumbersCardinal Numbers）和序数词（序数词（Ordinal NumbersOrdinal Numbers）两种。前者表示数量，后者表示顺序。高考重点要求：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 知识点概述一一、冠冠词词（一）（一）不定冠词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,aone-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 awhile,for a long time,a cup of,a bottle of,have a rest,have a talk,havea fever,have a goodtime,have(take)a walk,have

twelfth(第十二)的特殊拼写。（2）在 13-19 中，13-19 基数词在数词 3-9 后加-teen 构成。其中 13 和 15 发生拼写变化：thirteen 和 fifteen，相应序数词在基数词后加-th 构成。13-19 岁的少年用 teens(in ones teens 在某人十多岁时)。（3）在20-90 整十位数，在基数词2-9 之后加-ty 构成。其中20、30、40、50 拼法特殊。在构成相应的序数词时，将词尾y 变 i，再加-eth。表示二十多岁等用 twenty 等的复数 twenties(in ones twenties 在某人二十多岁时)。（4）两位数之间的数，由十位数加个位数构成，中间用连字符。构成序数词时，连字符前为基数词，后为序数词。如：二十五 twenty-five;第九十九 ninety-ninth.（5）100

cashier 前面表示类指，说明属哪类人。译文：星期六我作为超市出纳员每小时挣 10 美元。a/an 的用法规则：以元音音素开头的单词前用an，以辅音音素开头的单词前用 a。例 2、One way to understand thousands of new words is to gain_ goodknowledge of basic word formation.A./B.the C.a D.one答案为 C。【解析】knowledge 是不可数名词，当被某些修饰语修饰时，前面要加不定冠词，如：He has a very good knowledge of English.他在英语方面有丰富的知识。例 3、Alexander Graham Bell invented _telephone in 1876.A./B.a C.the D.one答案为 C。【解析】the+可数名词单数表示一类泛指。例 4、The cakes are delicious.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；secondone 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.Several million B.Many million C.Several millions D.Manymillion答案为 A。【解析】在 million，hundred 等前如果有具体数字或 several 等词时，要用单数形式。many 一般不与 million 等词连用。在表示不确切数目时用复数，例如：表示“数百万”，英语为 millions of。译文：每天，世界上有百十万人通过email 传递信息。例 7、_ of the land in that district _covered with trees and grass.A.Two fifth.is B.Two fifth.are C.Two fifths.is D.Twofifths.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 ofC、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.It takes us _ hour or more to go to my hometown by _
