基数词不难记,找清规律很容易;十二以内词各异,
十三数到十九去,后加teen莫忘记;
二十、三十至九十,正式之后有-ty;
要说“几十几”,中间“-”别丢弃;
a hundred是“一百”,请你记住莫大意。 序数词 基变序、很容易,词尾加上“th”。“一”、“二”、”三”特殊记,结尾变成t,d,d
“八”减“t”,“九”去“e”,字母“f”替“ve”。遇“十”变“y”为“ie”,然后再加“th”,若是遇到几十几,只变个位就可以。§.时间的读法1)直接读法:先读小时,后读分钟
3:25
2) 间接读法:先读分钟,再读小时
①当分≤30分钟 分钟+past+小时
3:25
②当分>30分钟 (60-分钟)+to+(小时+1)
3:55
6:15__________6:30____________6:45_____________ three twenty-fivetwenty-five past threefive to four ※15minutes = a quarter ; 30minutes=half an hour数词的用法§、年、月、日的读法1、年份的表达方式
两位一读:2018 twenty eighteen
2000 two thousand ,twenty hundred
2001 two thousand and one
2、年、月、日同时表达时,一般应先写月、日,后写年。
在2001年5月4日:on May 4 th, 2001
3、表岁数或年代
in his twenties 在他20多岁时 in 1980s 在20世纪80年代
Tony's mom looks young and beautiful. It's hard to imagine she is already in her ______(fifty).fifities§、表顺序编号1、序数词表顺序
第一课:the first lesson 第一次:the first time
※序数词前常加定冠词“the”,如果序数词前有形容词性物主代词则去掉the.例如:his first book his fourteenth birthday
2、基数词表年级、班、行、房间、课的编号
“基数词居后,词首的字母大写”
第一课:Lesson One 九年级:Grade Nine 218房间:Room 218

It is said that the ________(two) biggest earthquake in Nepal killed
more than 8,000people.tenthsecond§、数词的确指和概指1.表示确指。表达确切的数量直接用基数词、分数、小数等。hundred,thousand,million,billion等前有具体数字时,不能用复数形式。300: three hundred 5000: five thousand
More than three ________(hundred) students in our school bought it.
2.表示概指。ten,hundred,thousand,million,billion等可以构成短语,表示不确切的数量。此时这些词用复数形式,不能被具体数字修饰,后面与of搭配。hundreds of thousands of

2、不定冠词用在序数词前表示“又一、再一”例如:I've tried three times, let me try a fourth time.我已经试过三次,让我再试一次吧。§、分数的表达法分数用基数词作分子,序数词作分母。分子大于1时,作分母的序数词用复数。
1/3 one third 2/5 two fifths
1/2 a half 1/4 a quarter
※分数作主语时,谓语动词的单复数由分数指代的名词的数决定。
