第5期,语法运用 Grammar in use英语数字的表达方式一、基数词1 one2 two3 three 4 four 5 five 6 six7 seven 8 eight 9 nine10 ten 11 eleven 12 twelve13 thirteen 15 fifteen 18 eighteen,20 twenty 21 twenty-one 30 thirty40 forty 50 fifty 80 eighty100 one hundred 1,000 one thousand1,000,000 one million,【总结】基数词的基本构成如下:1.1-12为基数词中的基本数词。2.13-19的基数词在数词3-9后加-teen构 成。其中13(thirteen),15(fifteen),18(eighteen)发生拼写变化。3.20-99之间的整十位数,在基数词2-9之 后加后缀-ty构成。其中20(twenty),30(thirty),40(forty),50(fifty),80(eighty)拼写发生变化。个位数不为零的十位 数,由十位数加个位数构成,中间用连 字符号。,4.整百位数由基数词1-9加hundred构成。百位数中若十位数不为零,百位数与十 位数之间用and连接,也可以省略;但 百位数后直接加个位数时,and 一般不 能省略。如:110(one hundred and ten);205(two hundred and five).,5.整千位数由基数词1-9加thousand构成。千位数带百、十、个位数可由千位数 直接加百、十、个位数构成。英语中 没有“万”这个单位。一万以上至百万 以下的数字都用“千”作单位表示。如:10,000(ten thousand);200,000(two hundred thousand)。6.百万以million作单位表示。7.十亿以billion作单位表示。,提示:1.1100-1900之间的整数也可以用百为单 位表示。如:1300(thirteen hundred)。2 hundred,thousand,million被several或 基数词修饰表示计数时不能用复数。如:several hundred(几百),three thousand(三千),two Million(二百万)。3 hundreds of(几百),thousands of(几千;成千上万),millions of(几百万)表示不 定数量。,二、序数词1st first5th fifth12th twelfth2nd second 8th eighth 20th twentieth3rd third 9th ninth 100th hundredth,【总结】序数词的基本构成如下:1.序数词1-3为特殊变化,即:first(第一),second(第二),third(第三)。2.序数词4-19在相应基数词词尾加-th构 成。注意fifth(第五),eighth(第八),ninth(第九)和twelfth(第12)的特殊拼 写。,3.20-99之间的整十位数在构成序数词时,将相应基数词词尾-y变成-i,再加-eth。如:twentieth(第20),fiftieth(第50)等。其余个位数不为零的十位数在构成序 数词时,十位数用基数词表示,个位数 用序数词表示。如:twenty-first(第21),thirty-seventh(第37)。,4.整百位数构成序数词时,在hundred后 面加上-th。如:(a/one)hundredth(第 100),two hundredth(第200)。百位数 含十位数和个位数构成序数词时,只需 将最后一个数变成序数词。如:(one)hundred(and)fifty-eighth(第158)。5.千至百万的数构成序数词时,同样是将 最后一个词变为序数词。如:(one)thousand two hundred(and)forty-second(第1242).,三、加减乘除A.加Addition is adding two or more numbers together to find their total.,Here 1 ball is added to 1 ball to make 2 balls.This would be written:1 plus 1 equals two.(1+1=2),B.减Subtraction is taking one number away from another.,If you have 5 apples,then subtract 2,you will have 3 left.This would be written:5 minus 2 is 3.(5-2=3),C.乘Multiplication is adding a number to itself a particular number of times.,If each child has five balloons,and there are four children,then they have twenty balloons totally.This would be written:5 multiplied by 4 equals 20.(54=20),D.除Division is separating(分开)something into parts.,4 friends want to share 16 watermelons equally.How do they divide the watermelons?This would be written:16 divided by 4 is 4.(164=4),实战演练I.你能用英语写出下列数字的基数词及序数词吗?试一试吧,不要看上面的提示哦!1.7 _ _2.11 _ _3.33 _ _4.99 _ _5.845 _
