数词何时用复数形式

英语中，数词包括基数词和序数词。通常情况下，基数词表示事物的数量，序数词表示事物的顺序。如：

1）There are three hundred and sixty-five days in a year.一年有三百六十五天。

2）Today is her tenth birthday,so she is very happy.今天是她的十岁生日，所以她很开心。

此外，我们还会遇到许多数词的复数形式，常见的有以下几种情况：

一、表示约数时，常用“hundreds/thousands/millions/...+of”结构，其中hundred, thousand,million等词均要用复数形式。如：

1）Hundreds of people want to get the job.数以百计的人想得到这份工作。

2）Thanks to Project Hope,thousands of children have better lives now.多亏希望工程，现在成千上万的孩子过上了更好的生活。

3）There are millions of living things on the earth.世界上有数以百万计的生物。

例1（2016年永州卷）Mount Tai is so famous that______people visit it every day.

A.hundred of B.seven hundreds of C.hundreds of

例2（2016年安顺卷）Unluckily,______people were killed in the earthquake.

A.two thousands B.thousand of C.two thousands of D.thousands of

例3（2015年天津卷）Basketball is so exciting that______people play it for fun.

A.million B.two millionsC.million of D.millions of

二、表示分数时，分子用基数词，分母用序数词。当分子大于1时，分母的序数词要用复数形式。另外，表达四分之几，可用“基数词+quarter(s)”。如：

1）Three sevenths of the students in this class have bought dictionaries.这个班七分之三的学生已经买了词典。

2）Three fourths of the world’s books and newspapers are written in English.世界上四分之三的书和报纸是用英文写的。

3）Three quarters of the water in this area has been polluted.这个地区四分之三的水已经被污染。

注意：分数与所修饰的名词之间需加介词of，当“分数+of+名词”结构作主语时，谓语动词须和of后的名词保持一致。

例4（2016年滨州卷）—What do you think of the environment here?

例6（2016年兰州卷）______of the students in Class 6 have lunch at school.

A.Two fifth B.One thirds C.Three fifth D.Three quarters

三、表示“某一世纪的几十年代”时，在年代后加s（或加’s）。如：

1）The TV play tells a story in the 1970s.这个电视剧讲述了20世纪70年代的一个故事。

2）Today we are going to show everyone clothes from the 1970s to the 1990s.今天我们要向大家展示20世纪70年代到90年代的服装。

四、表示“某人处于几十多岁”时，用表示整十的基数词的复数形式。如：

1）My uncle had his own company in his twenties.我叔叔在二十多岁时就有了自己的公司。

2）Karl Marx began to learn Russian in his sixties.卡尔·马克思六十多岁时开始学习俄语。

五、用在习惯用语中。如：a bunch of fives“一只手；拳头”；in twos and threes“三三两两”；by ones and twos“三三两两；零零散散”；by twos and threes“两三个一次；三三两两”；at sixes and sevens“乱七八糟；不和”；on all fours“匍匐；爬着”；to the nines“完美”等。如：

1）Some of us know he’s got a bunch of fives.我们中间有些人知道他的拳头很厉害。
