Just try your best to do it! 数词 一、主要内容 数词的定义，分类及用法二、知识要点1.定义：表示数目多少或者顺序先后的词。2.分类：基数词和序数词（1）基数词：定义：表示数目或者数量多少的词。用法：1112的基数词是独

2、立的单词，即： one，two，three，four，five，six，seven，eight，nine，ten，eleven，twelve。 21319的基数词以-teen结尾。如： fourteen，seventeen等，但13，15，18较特殊， 13thirteen 15fifteen 18eighteen。 32090的整十位均以-ty结尾。如： sixty，ninety，但20，30，40，50，80较特殊， 20twenty 30thirty 40forty 50fifty 80eighty。 4十位数与个位数之间要加连字符号“-”，如：28twenty-eight，96nine

3、ty-six。 5百位和十位（若无十位则和个位）之间加and，如：148one hundred and forty-eight 406four hundred and six。 6hundred（百），thousand（千），million（百万），billion（十亿）等前面即使有具体的数词，也不能在它们的后面加s。如：600six hundred，8百万eight million。 71000以上的数字，从后往前数每三位加一个逗号“，”第一个逗号前为千（thousand），第二个逗号前为百万（million），第三个逗号前为billion（十亿）。英语中无“万”这个词，我们可以用“几十个千

4、（thousand）”表示几万，“几百个千（thousand）”表示“几十万”。如：2，510two thousand five hundred and ten；84，296eight-four thousand twohundred and ninety-six；274，350two hundred and seventy-four thousand three hundred and fifty。 8hundred，thousand，million用复数形式修饰名词时要用“of复数名词”，如：数以百计的年轻人hundreds of young people；数以千计的书thousands

5、of books。注意：hundreds of thousands ofmillions of 复数名词，其前面不能加具体的数词，但可加several或 many。 9基数词单数名词形容词构成合成形容词。如：一个五岁的男孩a five-year-old boy；一座800米长的桥an 800-metre-long bridge；女子400米接力girls400-metre relay race。 句法功能：起名词或形容词的作用，在句中做主语，宾语，表语，定语或者同位语。Eg：Three from eight leaves five.八减去三得五。（做主语，宾语）My cell phone nu

6、mber is 135xxxxxx我的手机号码是135（做表语）We still have one hour left.我们还剩一个小时的时间。（做定语）We two will help you.我们两个会帮你的。（做同位语）（2）序数词定义：表示顺序和等级的词。用法：1基数词变序数词可利用口诀巧记：“一、二、三，特殊记，八去“t”，九去“e”，“ve”要用“f”替，见“y”变成“i”和“e”，词尾加上“th”，若是遇到几十几，只变个位就可以。”第一、第二、第三分别：first，second，third，eighteighth nineninth，fivefifth，twelvetwelfth

7、，twen- tytwentieth，fortyfortieth，twenty-fivetwenty-fifth。 2其余情况均在基数词后加th。如： sixsixth, nineteennineteenth , hundred hundredth, thousandthousandth等。 句法功能：在句中可做主语，表语，宾语或者定语等。Eg：The first is mine and the second is yours.第一个是我的，第二个是你的。（做主语）You are the second to come. 你是你第二个来的。（做表语）Do you prefer the first

8、 or the second？第一个和第二个你更喜欢哪一个呢？（做宾语）3.用法1表达时刻：小时、点钟、分钟、秒钟要用基数词。 “几点钟”用基数词加oclock。oclock可省略。如：现在是5点钟Its five（oclock）“几点过几分，30分钟”用介词past。如： 7：05five past seven；7：15fifteen（a quar- ter）past seven；7：30half past seven。“差几分几点”用介词“to”。注意：整点加“1”且用 60减去目前的分钟数。如：7：40twenty to eight；7：45fifteen（a quarter）to ei

9、ght。日常生活中的时间读法常常简化，直接按基数词的顺序读。如：7：05seven o five；7：15 seven fifteen。 2.表达编号：Lesson One the first lesson第一课；Bus No3the No3bus 3路公共汽车；表示住所时不用“No”如：302房间Room 302（读作：room three o two）；如果编号的数词比较长，一般用基数词。如：Page 457第457页；电话号码，用基数词，可单个读，重复的数字也可读“double”，如：three eight five five（double five） six three three（d

10、ouble three）。 3、表达日期年代：年份用基数词，先读前一位或两位，再读后两位。如：1999nine- teen ninety-nine；1900nineteen hundred； 2000two thousand；1905nineteen o five；年用基数词，日用序数词（读时前面加定冠词the）。如：1998年6月8日写作：June 8，1998；读作：June the eighth， nineteen ninety-eight或the eighth of June， nineteen ninety-eight。 4表达分数，小数，百分数：分子用基数词，分母用序数词，分子大于

11、“1”，分母则加“s”。如：13 one third，23two thirds；12 a（one）half， 14one fourth或a（one）quarter，34threefourths或three quarters。 5表达倍数：一倍用once，两倍用 twice，两倍以上用基数词times。如：5倍five times。 主要分为以下五种方式：倍数+as many/muchasEg：We have produced three times as many computers as we did last year.我们生产的计算机是去年的三倍之多。倍数+the size（weight

12、，height，depth，width，age，length) ofEg： China is almost twice/double the size of Mexico in area.在国土面积上，中国几乎是墨西哥的两倍大。倍数+what从句Eg：The length of the road is twice/double what it was three years ago.这条路是三年前的两倍长。倍数+比较级+than Eg：I am twice older than you. 我的年龄比你们大两倍。He has read three times more books than I

13、have.他读的书比我读过的多三倍。比较级+than+by+倍数程度Eg：The line is longer than that one by twice. 这根线比以前那根线长两倍。6、表达年龄：在资料统计中，用阿拉伯数字表示年龄，一般场合下多用单词，也可以用数字进行强调，正式的英语写作中，都用英语单词表达年龄。表示在“某人几十多岁”时用“in ones+整十数的复数形式”Eg： She is a student，16，from the United States.她是一个学生，十六岁，来自美国。 Im thirteen years old. 我十三岁。 He began to learn

14、 the piano at the age of four.四岁时，他开始学习钢琴。 When he was in his twenties，he became a very famous poet. 二十多岁的时候，他就成了一位非常有名的诗人。 在七岁时：at the age of seven，at seven，at age seven 一个七岁的女孩：a girl who is seven，a girl who is seven years old，a girl aged seven，a sevenyearold girl，a girl of seven7、特殊用法 1数词作主语，谓语动词

15、用单数。如： Two months is quite a long timeFour and two is sixWhats two and three？ 2一个半小时（一年半，一个半月可类推）onean hour and a half one and a half hours。 3不定冠词用在序数词前表又一、再一。如：Ive tried three times，let me try a fourth time意为：我已经试过三次，让我再试一次吧。 中考英语数词真题及详解1. of the land is covered with trees and grass in Pingjiang, Y
