數(shù)詞分為基數(shù)詞和序數(shù)詞兩種

1、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“-”連接。如：     eighty-five 85     twenty-six 26     （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： 

2、0;   three hundred and sixty-five 365     two hundred and six 206     （3）基數(shù)詞的復(fù)數(shù)形式。當(dāng)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：     several hun

3、dred years ago幾百年前     two thousand students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：     in the 1990s 20世紀(jì)90年代     in ones twenties在某人20多歲時 &

4、#160;   （2）用在習(xí)語中。如：     in twos and threes三三兩兩地 二. 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-two 42 forty-second第42     nine-h

5、undred 900 nine-hundredth第900   2. 當(dāng)序數(shù)詞用阿拉伯?dāng)?shù)字表示時，必須在數(shù)字后加上序數(shù)詞的最后兩個字母。如：     21st第21     32nd第32   3. 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：     Though he had failed tw

6、ice, he wanted to try a third time.     盡管他已失敗了兩次，他還想再試一次。     The little monkey had had three apples, and he wanted to eat a fourth one.

8、#160;  five eighths八分之五     （3）當(dāng)分子是1時，可以用one也可以用a。如：     a second = one second     a third = one third     （4）當(dāng)分母是2和4時，分別可以用half和quarter代替。如：     

9、;a half二分之一     three quarters四分之三   2. 百分?jǐn)?shù)     百分?jǐn)?shù)用percent表示。如：     forty percent百分之四十     three percent百分之三   3. 分?jǐn)?shù)、百分?jǐn)?shù)與主謂一致     分?jǐn)?shù)、百分?jǐn)?shù)的考查往往和主謂一致相聯(lián)系

10、。當(dāng)分?jǐn)?shù)、百分?jǐn)?shù)修飾可數(shù)名詞的復(fù)數(shù)時，謂語動詞用復(fù)數(shù)形式；當(dāng)分?jǐn)?shù)、百分?jǐn)?shù)修飾不可數(shù)名詞時，謂語動詞用單數(shù)形式。如：     Eighty percent of the students in our school come from Henan.     我們學(xué)校百分之八十的學(xué)生來自河南。     Three fourths of the
