高考英语语法系列训练（三）数词
I.知识点归纳
一．基数词和序数词
1. 基数词:表示数目的词为基数词
1)21-99的两位数，在十位数和个位数之间加连字符构成。如：fifty- three (53)
2)101-999的三位数由hundred加and再加两位数或末位数。如：three hundred and twenty-five (325)
3)基数词hundred，thousand，million，billion表示确切数目时不能加s如：five thousand students (五千个学生)，但在表示不确切数目时，要用复数形式，如：hundreds of／thousands of students(许多学生)
4)dozen和score的复数形式应注意以下几点：dozen(一打，十二个)；score(二十)；
当dozen与数词，或many，several等连用时，不加“s”，所修饰的名词前常省去“of’，例如：two dozen pencils(两打铅笔)；dozens of people(许多人)
注意：当后面的名词前有"these"，“those"，“them"，" us"等词时,应加"of "，如： a dozen of these people，two dozen of them .two score of people中应加“of"，但three score and ten people(七十人)中不加of，scores of people指“许多人”
2.序数词: 表示顺序的数词为序数词
1)序数词一般由基数词后+th构成，前面一般加定冠词the，表示“第几”。如：the two hundredth，the eighteenth。如加不定冠词，则意为“又一,再一”.如：I like the film very much, so I want to see it a second time.有时也可不加冠词，如： He was first in the race．The girl came out first/second in the contest．
2)以ty结尾的基数词构成序数词时，先把y改成i，再加eth。如：the twentieth，the fiftieth
3)不规则的序数词有以下几个：first，second，third，fifth，eighth，ninth，twelfth
4)“二十”以上的多位数，个位数用序数词，其余仍用基数词。如：ninety-third；one hundred and forty-ninth
5)基数词与序数词连用时，通常是序数词在前。如：the first two pages of the book(这本书的前两页)
3.其他几种数词
1)分数由基数词和序数词合成，分子用基数词，分母用序数词，分子大于1时，分母的序数词要用复数形式 如：1/3: one(a)third 2/3: two thirds 1/2 : one(a)half 1/4 one(a)quarter／one(a)fourth 3/4: three quarters 注意：a year and a half／one and a haft years(一年半) 2)小数点读point；“零”读o[au]或zero；小数点后的数字按个位基数词依次读出。如：0.62读作zero point six two 3)百分数由percent(percent)表示：29％ 一29 percent
二.数词在句中的作用
1.主语：Two of them are teachers． 2.定语：There are fifty students in our class．
3.宾语：Give me two． 4.表语：I'm eighteen now．
5.同位语：You may leave it to us two．6.状语：This room is one-sixth larger than that one．
三.时间表示法
1.钟点
1) 正读法------按时间表上的数字读：先读钟点数，后读分钟数。如：10：20— ten twenty
2) 倒读法------表示几点过几分，用介词past，多用在半小时以内(包括半小时);表示几点差几分，用介词to，多用在半小时以上(不包括半小时).如：9：30： half past nine(九点半)
7：05： five past seven(七点过五分) 8：50： ten to nine ( 八点五十；差十分九点)
3)表示整点 8:00：eight o'clock (sharp)
4)表示在某个钟点，用介词at.如：They begin to work at half past seven．
2.日期
1) 年代用基数词，在某年要用介词in。如：He was born in l983．他出生于1983年。（1983读成nineteen eighty-three）
2)月份首字母要大写，在某月也用介词in，如果有年代出现，在月份名后加年代，中间用逗号。如：It happened in January，1999．这事发生在1999年1月。
3)月日同时出现时可有两种表示法
英国说法：顺序为先日后月。如:4(th)May(五月四日——读成: the fourth of May)
美国说法：顺序为先月后日。如：May 4(th)(五月四日——读成: May the fourth)
表示在某月某日，不管用在前还是在后，都用介词on如：The meeting will be held on March 9(th)．We'll leave for Shanghai on 8th June．
4)年月日同时出现时，年代位于最后，其前加逗号 如：Mary was born on January 1st，1990，
