数词用法归纳
一、定义与分类
数词是指表示数目多少或顺序先后的词。
表示数目多少的数词叫基数词,如one,five,ten,thirty,sixty-five等;
表示顺序先后的数词叫序数词,如first,sixth,tenth,twenty-first等。
数词用法相当于名词和形容词,在句中可用作主语、宾语、表语、定语、同位语等。
二、基数词
1.英语中没有“万”这个读数单位,要表示汉语中的“万”,英语需借用thousand一词,如“一万”用“十个千”表示(tenthousand),“十万”用“一百个千”表示(onehundredthousand)。
2.用作基数词单位的hundred,thousand,million,billion通常不带复数词尾-s,但若用于表示数百、数千、数百万这样的泛指,则用复数。
如:
Abouttwothousandpeoplediedintheearthquake.大约有两千人在地震中丧生。
Thousandsofpeoplegototheseasideeveryyear.每年成千上万的人到海滨去。
3.表示整十的基数词用复数形式可以表示人的大约岁数或年代。
如:
Heisinhisearlytwenties.他才二十出头(from)。
Thistookplaceinthe1930s.这事发生在20世纪30年代。
三、序数词
1.许多序数词是由相应的基数词后加词尾-th构成的,如four/fourth,six/sixth,ten/tenth,sixteen/sixteenth,但是nine变为序数词是ninth,而不是nineth。
2.twentieth,thirtieth,fortieth等表示整十的序数词,由相应的基数词将词尾y改为ie,再加-th构成。
3.first,second,third通常可缩写为1st,2nd,3rd。
凡是以th结尾的序数词可缩写为“基数词+th”:
4th,5th,9th,11th,60th,128th等。
4.非整十的多位数,将个位数变成序数词即可:
twenty-first(第21),thirty-sixth(第36),ninety-ninth(第99),threehundredandsixty-fifth(第365)等。
5.hundred,thousand,million等序数词形式为hundredth,thousandth,millionth等。
6.序数词前通常要用定冠词,但表示考试或比赛等的名次时,通常可省略其前的定冠词。
如:
Myroomisonthesecondfloorandhisonthethird.我的房间在三楼,他的房间在四楼。
Hewas(the)thirdintheexam.他考试得了第三名。
注:
有时序数词前不用定冠词,而用不定冠词,表示次第在原有基础上的增加。
如:
We’llhavetodoitasecondtime.我们得再做一次(from)。
序数词前用定冠词和不定冠词的区别在于:
定冠词表特指,不定冠词表泛指,有类似another的意思,但比another的意思更明确。
四、分数、倍数、小数和百分数
1.分数。
分数由基数词和序数词构成:
分子用基数词,分母用序数词,当分子超过“1”时,分母用复数。
如:
twothirds=2/3 threefifths=3/5
注:
1/2通常读作a[one]half,一般不读作asecond;1/4可读作a[one]fourth,也可读作a[one]quarter。
2.倍数。
英语中表示倍数时通常借助half,double,twice,threetimes等之类的词。
如:
They'retwicethesizeofchickens.它们比鸡大一倍。
Theirhouseisaboutthreetimesasbigasours.他们的房子大约有我们房子三倍大。
3.百分数。
百分数由基数词和百分号(%)组成,百分号(%)读作percent。
如:
thirtypercent=30% 60percent=60%
