1、数 词数词分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。 一.基数词 1.基数词就注意以下几点： （1）几十几的基数词的十位数与个位数之间要用连字符“-”连接。如： eighty-five85 twenty-six26 （2）三位数的基数词须在百位和十位（若无十位则和个位）之间用and连接。如： threehundredandsixty-five365 twohundredandsix206 （3）基数词的复数形式。当基数词hundred,thousand,million,billion等词前有具体数词或several修饰时，必须用单数。如： several

2、hundredyearsago几百年前 twothousandstudents两千个学生 2.基数词的特殊用法： （1）表示“几十年代”或“几十岁”时，用逢十的基数词的复数形式。如： inthe1990s20世纪90年代 inonestwenties在某人20多岁时 （2）用在习语中。如： intwosandthrees三三两两地 二.序数词 序数词应注意的几点事项： 1.多位数的基数词变成序数词时，只需将末位基数词变成序数词，前边的基数词不变。如： forty-two42forty-second第42 nine-hundred900nine-hundredth第900 2.当序数词用阿拉伯数

3、字表示时，必须在数字后加上序数词的最后两个字母。如： 21st第21 32nd第32 3.序数词前一般要用定冠词the，如果序数词前用a或an时，则表示“又一；再一”（没有具体范围的限制）。如： Thoughhehadfailedtwice,hewantedtotryathirdtime. 尽管他已失败了两次，他还想再试一次。 Thelittlemonkeyhadhadthreeapples,andhewantedtoeatafourthone. 那只小猴子已经吃了3个苹果，他还想再吃一个。 三.分数和百分数 1.分数 （1）分数的分子用基数词，分母用序数词。如： onefifth五分之一 o

4、netenth十分之一 （2）当分子大于1时，分母用序数词的复数。如： twothirds三分之二 fiveeighths八分之五 （3）当分子是1时，可以用one也可以用a。如： asecond=onesecond athird=onethird （4）当分母是2和4时，分别可以用half和quarter代替。如： ahalf二分之一 threequarters四分之三 2.百分数 百分数用percent表示。如： fortypercent百分之四十 threepercent百分之三 3.分数、百分数与主谓一致 分数、百分数的考查往往和主谓一致相联系。当分数、百分数修饰可数名词的复数时，谓语

5、动词用复数形式；当分数、百分数修饰不可数名词时，谓语动词用单数形式。如： EightypercentofthestudentsinourschoolcomefromHenan. 我们学校百分之八十的学生来自河南。 ThreefourthsofthestudentsinmyclassareinterestedinEnglish. 我们班四分之三的学生对英语感兴趣。 Twothirdsofthewaterontheearthisseawater. 地球上三分之二的水是海水。 四.倍数的表示法 1.表示“几倍大小（长短；数量）”，由“倍数+thesize（length,amount.）”结构组成。如

6、： Theearthisforth-ninetimesthesizeofthemoon. 2.表示“比大几倍”，由“倍数+形容词（副词）比较级+than+被比较部分”结构组成。如： Thisboxisthreetimesbiggerthanthatone. 3.表示“是倍”，由“倍数+as+形容词+as+被比较部分”结构组成。如： Ourfactoryistwiceasbigastheirs.数 词( ) 1.
