數詞語法講解及練習題
數詞分兩類:基數詞和序數詞.表示數目的詞叫基數詞,表示須序的詞叫序數詞。下面學習啦小編為大家帶來數詞語法講解及練習題，歡迎大家學習!
一、數詞語法講解
1.基數詞
1)基數詞一般可寫成如345或three hundred and forty-five。
2)基數詞一般是單數形式，但遇下列情況，常用復數：
a. 與of 短語連用，表示概數，不能與具體數目連用，如scores of people 指許多人;
b. 在一些表示"一排"或"一組"的詞組里。例如：
They arrived in twos and threes. 他們三三兩兩的到了。
c. 表示"幾十歲"。
d. 表示"年代"，用 in +the +數詞復數。
e. 在乘法運算的一種表示法里，如Three fives is(are)fifteen。
2.序數詞
序數詞的縮寫形式如first---1st second---2nd thirty-first---31st等。
3.數詞的用法
1)倍數表示法
a. 主語+謂語+倍數(或分數)+ as + adj. + as。例如
I have three times as many as you. 我有你三倍那么多。
b. 主語+謂語+倍數(分數)+ the size (amount，length…) of…。例如：
The earth is 49 times the size of the moon. 地球是月球的49倍。
c. 主語+謂語+倍數(分數)+ 形容詞(副詞)比較級+ than…。例如：
The grain output is 8 percent higher this year than that of last year. 今年比去年糧食產量增加8%。
d. 還可以用by+倍數，表示增加多少倍。例如：
The production of grain has been increased by four times this year. 今年糧食產量增加了4倍。
2)分數表示法的構成：基數詞代表分子，序數詞代表分母。分子大于1時，分子的序數詞用單數，分母序數詞用復數。例如：
1/3 one-third; 3/37 three and three-sevenths.
