3. 基数与序数词变化总结:
1)基数总结:记住基数的1-10,其它多数都是从这些变化得来
11-19:多是加teen,11(eleven),12(twelve)特别,13是(three变为thir+teen),15(five去e+teen),但19(nine不去e+teen),18(以t结尾直接+een),14/16/17直接加teen
20-90:多是加ty,变法同12-19,20(twenty特殊),30变thir,40变for,50去e但,80以t结尾直接加y,90要不去e
2)序数总结:多是加th,
1-10,除1(first),2(second),3(third),5和9要去e加th,8以t结尾直接加h,其它都是加th,
11-19,除12变ve为f加th,其它统统都是基数词上加th
20-90,统统都是基数词上变y为i加eth,无例外情况
3)其它总结:
1(one),11(eleven),第1(first),第11(eleventh),除第11是规则的加th,基它各不相同
2(two),12(twelve),20(twenty),第2(second),第12(twelfth),第20(twentieth),第12/20有规则,其它无则
3(three),13(thirteen),30(thirty),第3(third),第13(thirteen),第30(thirtieth),基本为thir加teen/ty/eth
8/18/80 eight/eighteen/eighty 第8/18/80 eighth/eighteenth/eightieth,以t结尾少加了t
9/19/90 nine/nineteen/ninety 第9/19/90 ninth/nineteenth/ninetieth,除第9去e,其它都不e规则变化
3. 年月日,上午/下午,时间
1)年月日,先读月和日,再读年。月有专用词,日要用序数词(可省略the),年用虽用基数词,但两位两位的读
例1:1999/7/23 简写法:July 23,1999 读法:July (the) twenty-third,nineteen ninety-nine
//注:这里的the可省,1999要两位两位的读,不能读成one thousand,nine hundred and ninety-nine
例2:1905/1800读法:nineteen hundred and five/eighteen hundred
总结:年的读法,中间没零不加and,中间有零加and,英文中年的写法和中文一样,还是写的数字

例:There will be no water tomorrow from 8 a.m. to 3 p.m 明天上午8点到下午3点没水

1/4 quarter(特殊) 3/4 three quarters //注:四分之几英文中有专有词quarter表四分之。。。
2)读小数:统统用基数词,小数点读作point,点前不管多大的数读法基数词,点后多个小数读法同电话号码
3.4 three point four 0.2 zere point two 4.25 four point two five
1346.3452 One thousand three hundred and forty-six point three four five two
5. 电话号码
直接用基数词按顺序读出来,遇到连一起的重复数字也可用double 例:110 one one zero/double one zero
