小学英语数词及专项训练

小学英语数词及专项训练一、数词的分类：基数词和序数词。基数用于表示数量多少，而基数词用于表示次序，常在日期中出现。区别：基数词前面没有“the”；序数词前一定要有“the”。1、超过二十以上的两位数需要在个位和十位之间加上“-”。如：21twenty-one2、用基数词来修饰可数名词时，一定别忘了它的复数形式。如：十八个男孩eighteenboys3、用基数词修饰不可数名词时，如是复数，变它的量词为复数。如：两碗米饭twobowlsofrice4、序数词一般加“th”，特殊的有：first,second,third,fifth,eighth,ninth,twelfth；二十及二十以外的整十：twentieth,thirtieth,fortieth…“第几十几”：前面整十不变，后面“几”改为序数词。如：88eighty-eighth巧记基数词和序数词：1,2,3,特殊记,加th从4起;8少t,9去e,逢5逢12ve变f;

20~90,y要变ie;若是几十几,前基后序别倒位.二、数词的表示方法：基数词序数词对照表1onefirst1th2twosecond2nd3threethird3rd4fourfourth4th5fivefifth5th6sixsixth6th7sevenseventh7th8eighteighth8th9nineninth9th10tententh10th11eleveneleventh11th12twelvetwelfth12th13thirteenthirteenth13th14fourteenfourteenth14th15fifteenfifteenth15th16sixteensixteenth16th17seventeenseventeenth17th18eighteeneighteenth18th19nineteennineteenth19th20twentytwentieth20th21twenty-onetwenty-first21st22twenty-twotwenty-second22nd23twenty-threetwenty-third23rd24twenty-fourtwenty-fourth24th25twenty-fivetwenty-fifth25th26twenty-sixtwenty-sixth26th27twenty-seventwenty-seventh27th28twenty-eighttwenty-eighth28th29twenty-ninetwenty-ninth29th30thirtythirtieth30th40fortyfortieth40th50fiftyfiftieth50th60sixtysixtieth60th70seventyseventieth70th80eightyeightieth80th90ninetyninetieth90th100onehundredonehundredth100th三、数词的用法1.章节、页数的读法第一章：thefirstchapter;ChapterOne第二节：thesecondsection;SectionTwo第三课：thethirdlesson;LessonThree第463页：pagefoursixthree第2564页：pagetwofivesixfour或twenty-fivesixty-four注意：如果页码的数字较长，通常用基数词。2.房间、门牌、电话号码的读法第305房间：Roomthreeo（零）five长安街76号：seventy-sixChang'anStreet电话号码：204-2244：telephonenumbertwoo（零）fourtwotwo（doubletwo）fourfour十一路公共汽车：Bus（No.）eleven3.年代、日期、时刻的读法（1）年份是四位数字时，各分成二位来读，eg.公元1995年：1995（=nineteenninety-five）
