(二)数词
基数词和序数词的相互转换
(1)一般来说,序数词是由相应基数词词尾加th构成。
(2)十位整数变序数词的构成方法是:将y变为i,再加eth。
(3)两位或两位以上的基数词变序数词时,仅将个位数变为序数词。
此外,常考的基数词、序数词一般会在100以内,具体见下表:
one—first two—second three—third four—fourth five—fifth six—sixth seven—seventh eight—eighth nine—ninth ten—tenth eleven—eleventh twelve—twelfth thirteen—thirteenth fourteen—fourteenth fifteen—fifteenth sixteen—sixteenth seventeen—seventeenth eighteen—eighteenth nineteen—nineteenth twenty—twentieth thirty—thirtieth forty—fortieth fifty—fiftieth sixty—sixtieth seventy—seventieth eighty—eightieth ninety—ninetieth
与数词相关的表达法
(1)分数由基数词作分子、序数词作分母构成。除分子是“1”的情况外,序数词都要用复数形式。
(2)表示某人的大约年龄,即“几十多岁”时,使用基数词的复数形式。“in sb's+整十的基数词的复数”意为“在某人几十多岁时”,如:in his fifties。
(3)当hundred, thousand, million, billion前面有基数词时,用单数形式,词尾不加s;前面有many, several, a few修饰时,仍用单数形式,如:several billion years。
(4)“数词+普通名词+形容词”构成的合成形容词中,数词和普通名词都要用单数形式。
倍数表达法
(1)倍数+as+形容词(副词)原级+as ...
My income is twice as much as yours.我的收入是你的2倍。
(2)倍数+the size/length/width/depth/height of ...
My house is twice the size of his.我的房子是他的两倍大。
(3)倍数+that of ...
① The size of my house is twice that of his.我的房子是他的两倍大。
