初中英語數(shù)詞專項練習(xí)

1、數(shù)詞數(shù)詞分為基數(shù)詞和序數(shù)詞兩種。表示數(shù)目或數(shù)量多少的詞叫基數(shù)詞；表示數(shù)目順序的詞叫序數(shù)詞。一.基數(shù)詞1 .基數(shù)詞就注意以下幾點：(1)幾十幾的基數(shù)詞的十位數(shù)與個位數(shù)之間要用連字符f”連接。如：eighty-five85twenty-six26(2)三位數(shù)的基數(shù)詞須在百位和十位(若無十位則和個位)之間用and連接。如：threehundredandsixty-five365twohundredandsix206(3)基數(shù)詞的復(fù)數(shù)形式。當基數(shù)詞hundred,thousand,million,billion等詞前有具體數(shù)詞或several修飾時，必須用單數(shù)。如：severalhundredyear

2、'ago幾百年前twothousandstudents兩千個學(xué)生2 .基數(shù)詞的特殊用法：(1)表示幾十年代”或幾十歲”時，用逢十的基數(shù)詞的復(fù)數(shù)形式。如：inthe1990'20世紀90年代inone'twenties在某人20多歲時(2)用在習(xí)語中。如：intwosandthrees三三兩兩地2 .序數(shù)詞序數(shù)詞應(yīng)注意的幾點事項：1 .多位數(shù)的基數(shù)詞變成序數(shù)詞時，只需將末位基數(shù)詞變成序數(shù)詞，前邊的基數(shù)詞不變。如：forty-two42forty-second第42nine-hundred900nine-hundredth第9002 .當序數(shù)詞用阿拉伯數(shù)字表示時，必須在數(shù)字

3、后加上序數(shù)詞的最后兩個字母。如：21st第2132nd第323 .序數(shù)詞前一般要用定冠詞the,如果序數(shù)詞前用a或an時，則表示又一；再一"(沒有具體范圍的限制)。如：Thoughhehadfailedtwice,hewantedtotryathirdtime.盡管他已失敗了兩次，他還想再試一次。Thelittlemonkeyhadhadthreeapples,andhewantedtoeatafourthone.那只小猴子已經(jīng)吃了3個蘋果，他還想再吃一個。3 .分數(shù)和百分數(shù)1 .分數(shù)(1)分數(shù)的分子用基數(shù)詞，分母用序數(shù)詞。如：onefifth五分之一onetenth十分之一(2)當

5、詞用單數(shù)形式。如：EightypercentofthestudentsinourschoolcomefromHenan.我們學(xué)校百分之八十的學(xué)生來自河南。ThreefourthsofthestudentsinmyclassareinterestedinEnglish.我們班四分之三的學(xué)生對英語感興趣。Twothirdsofthewaterontheearthisseawater.地球上三分之二的水是海水。4 .倍數(shù)的表示法1 .表示幾倍大?。ㄩL短；數(shù)量）”，由值數(shù)+thesize（length,amount.）”結(jié)構(gòu)組成。如：Theearthisforth-ninetimesthesizeof
