初一基数词序数词练习题(含答案)(DOC 6页).doc

1、一、基数词下面把100以内的基数词分为四类。第一类：one一 two二 three三 four四 five五 six六 seven七 eight八 nine九ten十eleven十一 twelve十二这一类共计十二个单词，在结构上与其他的基数词相比较是特殊的，就象不规则的动词一样，要求逐个的硬背下来，这对学好其他的基数词和序数词都是及其重要的。 2、第二类：thirteen十三 fourteen十四 fifteen十五 sixteen十六 seventeen十七eighteen十八 nineteen十九这一类基数词共有七个。它们在结构上有两个特点：一是在发音方面都有两个重音；二是在拼法上都有后

2、缀teen。除了thirteen和fifteen之外，都是纯粹地在另一个基数词的后面加上后缀teen。但要注意eighteen的拼法，eight本身有t字母，因此只加een。 3、第三类：twenty二十 thirty三十 forty四十 fifty五十 sixty六十 seventy七十eighty八十 ninety九十这类基数词共有八个。都是十位的整数，均以后缀ty结尾。其中sixty、seventy、eighty、ninety基本上是在相应的基数词后面加上后缀ty。但要注意eighty的拼法，eight本身有t字母，因此只加y。 4、第四类：这一类和很简单，可以看成是一种合成词。其结构方

3、式是：用十位整数加上个位整数，其间用连字符号“”连接，表示“几十几”。这类基数词的变化都是规则的。如：twenty-one二十一 forty-six四十六seventy-eight七十八 ninety-five九十五二、序数词下面把199的序数词也分为四个类。1、第一类first(1st)第一second(2nd)第二third(3rd)第三（在括号里的是缩写形式，均在阿拉伯数字后面加上相应序数词的最后两个字母构成，以下各类与此相同。）这类序数词只有三个，在整个序数词里面是特殊的，就和第一类基数词一样，需要逐个地硬记下来。 2、第二类：fourth(4th)第四 fifth(5th)第五six

4、th(6th)第六 seventh(7th)第七eighth(8th)第八 ninth(9th)第九tenth(10th)第十 eleventh(11th)第十一twelfth(12th)第十二 thirteenth(13th)第十三fourteenth(14th)第十四 fifteenth(15th)第十五sixteenth(16th)第十六 seventeenth(17th)第十七eighteenth(18th)第十八 nineteenth(19th)第十九这一类序数词共有十六个。均在相应的基数词后面加上后缀th构成。要注意其中fifth、eighth、ninth、twelth四个词的拼法

5、。 3、第三类：twentieth(20th)第二十 thirtieth(30th)第三十fortieth(40th)第四十 fiftieth(50th)第五十sixtieth(60th)第六十 seventieth(70th)第七十eightieth(80th)第八十 ninetieth(90th)第九十这一类全是十位整数的序数词，共八个。它们的构成方法是：先将相应的十位整数的基数词词尾ty中的y改成i，然后在加上后缀eth。 4、第四类：thirty-first(31th)第三十一 sixty-second(62nd)第六十二eighty-seventh(87th)第八十七 ninety-

6、eighth(98th)第九十八这类表示“第几十几”的序数词，跟表示“几十几”的基数词一样简单。在构成方法上均由基数词“几十几”变化而来，十位数不变，仅把个位上的基数词变成序数词就行了。 基数词及序数词重要用法1. 基数词的用法基数词用于表示事物的数量，在表示基数词时，要特别注意hundred, thousand, million, billion等几个词的用法：若其前用了基数词，则不论其面是否有of，都必须用单数形式(此时若带of则通常表示特定范围中的一部分)；若泛指数百、数千、数百万等，则用 hundreds of, thousands of, millions of 等这样的结构。如：T

9、lifetime is near the Alps. 乔治一生中找到的第一百个山洞在阿尔卑斯山附近。注：序数词前有时可用不定冠词，表示“每一，又一”。如：Well have to do it a second time. 我们将再做一遍。基变序口诀基变序，有规律 词尾加上-ed(fourth,sixth) 一、二、三，特殊例， 结尾字母t,d,d(first,second,third) 八去t,九去e,(eighth,ninth) ve要用f替;(fifth,twelfth) ty将y改成i, th前面有个e。 若是碰到几十几， 前用基来后用序。 或记忆为：一、二、三，特殊记，词尾字母t,d,
