【第2篇 小學英語語法知識點總結：數(shù)詞
表示數(shù)目多少或順序多少的詞叫數(shù)詞，數(shù)詞分為基數(shù)詞和序數(shù)詞。表示數(shù)目多少的數(shù)詞叫基數(shù)詞；表示順序的數(shù)詞叫序數(shù)詞。
一、基數(shù)詞
1）基數(shù)詞寫法和讀法： 325 three hundred and twenty-five；
2）基數(shù)詞一般是單數(shù)形式，但下列情況，常用復數(shù)：
a. 與of 短語連用，表示概數(shù)，不能與具體數(shù)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；
如：they arrived in twos and threes. 他們三三兩兩的到達了。
c. 表示“幾十歲”；

二、序數(shù)詞
序數(shù)詞的縮寫形式： first—1st second—2nd thirty-first—31st

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(shù)（分數(shù)）+ 形容詞（副詞）比較級+ than…
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(shù)，表示增加多少倍
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(shù)表示法
構成：基數(shù)詞代表分子，序數(shù)詞代表分母。分子大于1時，分子的序數(shù)詞用單數(shù)，分母序數(shù)詞用復數(shù)：
1/3 one-third ； 3/37 three thirty-sevenths.
