初升高總復習3數(shù)詞

初升高總反復數(shù)詞數(shù)詞：表示數(shù)目多少或順序先后的詞叫數(shù)詞。數(shù)詞有兩種：

表示數(shù)目多少的數(shù)詞叫基數(shù)詞，如：one，ten，twenty-three；

表示順序先后的數(shù)詞叫序數(shù)詞，如：first，third，twentieth。英語名稱：Numeral

縮寫形式：num.

1.基數(shù)詞

基數(shù)詞相當于名詞，在句中可作主語、表語、定語、狀語等。

［例句］

ThreeofmyclassmatesarefromShanghai.Iamtwentythisyear.Theyhavefourclassesinthemorningandthreeintheafternoon.2.基數(shù)詞的構成結構21~99的兩位數(shù)字，在10位和個位之間加連字符構成，如89eighty-nine.101~999的三位數(shù)字，由hundred加and再加二位數(shù)或末位數(shù)字，如：101-onehundredandone,223-twohundredandtwenty-three.四位以上數(shù)字，應從個位起向前數(shù)三位加逗號，讀作thousand;再數(shù)三位加第二個逗號，讀作million;再數(shù)三位加逗號，讀作billion，其讀法如下：1001-onethousandandone5386-fivethousand,threehundredandeighty-six3.

數(shù)詞的用法：1)表示年、月、日，“年”用基數(shù)詞，“日”用序數(shù)詞。如：Mayeleventh，20102)表示時間。如：It’seleventwenty.3)表示編號。編號既可以用基數(shù)詞表示，也可以用序數(shù)詞表示。區(qū)別是基數(shù)詞用在名詞之后，序數(shù)詞用于名詞之前，并加定冠詞。如：LessonNine；theNinthLesson4)序數(shù)詞前加冠詞“a”表示“再一次”。如：CanItryasecondtime?要注意的是hundred,thousand,million與billion的用法。①前面有別的基數(shù)詞時，即若干個百、千、百萬、十億時，其本身都不要加s，如：threehundredstudents。②若表示成百，成千或數(shù)百，數(shù)千時，前面不能有基數(shù)詞，但其本身要用復數(shù)形式，然后+of+名詞復數(shù)。如：fivehundredstudents；millionsofpeople4.

與數(shù)詞相關的主謂一致原則1)當名詞短語的中心詞為表示時間、路程、金錢或重量等的復數(shù)名詞時，往往根據(jù)意義一致的原則，把這些復數(shù)名詞看作一個整體，謂語采用單數(shù)形式。［例句］Twentydollarsisnotenough.二十美元不夠。2）如果“數(shù)詞”是單用時，則表示人或物，謂語動詞一般用復數(shù)。［例句］Threewerekilledandtenweremissinginthataccident.

在那起事故中，三人被殺，十人失蹤。2.

序數(shù)詞1)序數(shù)詞的構成：★大多數(shù)的序數(shù)詞是由基數(shù)詞加-th構成。如：seven―

seventh；ten―

tenth★以-t結尾的基數(shù)詞只在詞尾加-h。如：eight―

eighth★以-ve結尾的基數(shù)詞改-ve為-f再加-th。如：five―

fifth；twelve―

twelfth★以-y結尾的基數(shù)詞改-y為-ie再加-th。如：twenty―

twentieth，thirty―

thirtieth★幾十幾的序數(shù)詞只在個位數(shù)上有所改變。如：twenty-one―

twenty-first；thirty-three―

thirty-third★特殊的序數(shù)詞：one―

first；two―

second；three―

third；nine―

③1stFebruary④1/2。倍數(shù)的講法有所不同。兩倍用twice,而三倍以上用數(shù)詞加times,如：HehasthreetimesasmanybooksasIhave.表示時間：7：05sevenfivefivepastseven6:55sixfifty-fivefivetoseven9:30halfpastnineninethirty10：00teno’clock其他數(shù)字表示法小數(shù)的小數(shù)點讀作point，零讀作o或zero,小數(shù)點后面的數(shù)字按個位基數(shù)詞依次讀出。分數(shù)分子用基數(shù)詞，分母用序數(shù)詞，當分子大于1時，分數(shù)要在序數(shù)詞上加s，但1/2用onehalf,1/4用aquarter.1/3

讀作onethird而

2/3

讀作twothirds。百分數(shù)(%)，讀作percent(percent),但不論是多少均用作單數(shù)形式不能加s?！究碱}鏈接】1.—What’sthetime,please?—It’s_______.A.ninethirty-five

序數(shù)詞前面加定冠詞the,表示順序，即

“第幾”；加不定冠詞a/an,表示“再一次，又一次”，相當于another。2.

hundred,thousand等詞，與數(shù)詞連用，用單數(shù)；與of連用，用復數(shù)。3.

a/an表示泛指,the表示特指。一般情況下，第一次出現(xiàn)的人和物用a/an,第二次出現(xiàn)時，用the。4.

名詞前面加the,名詞表示具體的建筑物或實物；名詞前面零冠詞（one），名詞表示抽象的概念。<一>根據(jù)所給的漢語及句意，用恰當?shù)膯卧~或短語完成句子：1.Thereare______________________(三十或三十一)daysinamonth.2.Themanliveson________________(四十)floor.3.Whatwillbethepopulationoftheworldbytheendofthe___________(二十)century?4.Mother’sDayisonthe___________(第二)SundayinMay.5.About___________(一半)ofhisbooksareinEnglish.6.Thereis______pictureof___________elephanton___________wall．7.Thisis___________usefulbook．I'vereaditfor___________hour．thefortieththirtyorthirty-onetwentiethsecondahalfaantheaan8.Let'sgooutfor___________walk．9.It'stoohot．Open___________door，please．10.Thereis___________womanover
