英语16数词

第十六讲数词

一学习目标

了解数词的考点。

二考点解析

数词分为两种:基数词(表示数目)和序数词(表示顺序)。

考点一dozen 和score

1.dozen(一打,十二),score(二十)与具体数词或与many,several 等连用时,后不加-s,所修饰的名词前介词of有无均可。但是习惯上score多与of连用,而dozen很少与of连用。

如:

two dozen eggs 两打鸡蛋,

many dozen pencils好多打铅笔;

two score of eggs 40个鸡蛋;

three score of people 60个人。

dozen,score的复数形式后接of时,表示“许多”。

如: dozens of eggs几十个鸡蛋,scores of pencils几十支铅笔。

2.当所修饰的名词之前有限定词these, those, my, your等或是修饰人称代词宾格them,us,you 时,这时需要加of.

如:two dozen of these pens, three score of them

考点二分数的表达法

分子用基数词,分母用序数词,若分子大于1,则分母用复数。如:one-fourth(a quarter) 1/4;two-fifths 2/5。

(2016·全国乙)Two-thirds believe more families will follow the example of Obama’s family.

三分之二的人认为会有更多的家庭模仿奥巴马家庭的做法。

考点三年龄的表达法

表示某人的确切年龄,用“基数词+year(s) old”或者“at the age of+基数词”,也可直接用基数词;表示某人几十多岁时,用“in one’s+基数词的复数(如twenties,thirties等)”来表达。

She is still in her twenties.

她才二十几岁。

考点四年龄的表达法

表示“几十年代”时,在年份后加-s或-’s。

(2016·全国乙)In the 1960s we were all a little wild and couldn’t get away from home far enough or fast enough to prove we could do it on our own.

在20世纪60年代,我们都有点不安分,想尽快离家或离家远点来证明自己能够自立。
