1、中考英语语法专项复习 数词 中考对数词的考查主要围绕基数词和序数词的用法、时刻表达法、年、月、日表达法、电话号码及编号、分数的表达法、百分数的表达法、加减乘除表示法、hundred、thousand、million、billion的用法。卷面中数词所占分值约为 2-3分左右，一般分布在单选、完形填空、语法填空,翻译中。主要掌握1-13及20、21等的序数词的形式，其它序数词都是在基数词末尾加-th，是有规律可循的。onefirstsixsixtheleveneleventhtwosecondsevenseventhtwelvetwelfththreethirdeighteighththirte

2、enthirteenthfourfourthnineninthtwentytwentiethfivefifthtententhtwenty-onetwenty-firstthirtythirtieth另外，序数词的缩略形式是由阿拉伯数字加序数词的最后两个字母构成。例如：1st, 25th。基数词记忆口诀：基数词很容易，0至12词各异，单独记。13至19，以teen结尾不要丢；20至90，整十后面有个ty；几十几，也容易：先说几十，再说几，中间短杠“-”加上去。hundred是一百，百内数字记心怀。几百几，挺容易：先说几百，再说几，中间and加上去。thousand是一千，千内数字记心间。序数词

3、记忆口诀：基变序，很容易，基后th跟上去，第一、二、三要牢记，因为它们是特殊的（first、second、third）。8去t，9去e；ve要用f替，5 和12记心里；y尾单词变ie，此类词都是整十的；上述变化要牢记，th后面跟上去。要变几十几，也是很容易：只变个位就可以。二、时刻表达法。思维导图记知识点时刻表达法先说分钟，后说钟点先说钟点，后说分钟表示时刻有两种说法： 1) 先说分钟，后说钟点。几点过几分，分钟不超过三十分钟时用past。例如：Its five past eight now. 现在是八点（过）五分。几点差几分或差几分几点，差的分钟数不超过二十九分钟时,用to。例如：Its t

4、wenty-nine to eight. 八点差二十九分。Its a quarter to eight. 差一刻八点。2)先说钟点，后说分钟。在日常生活中，为了简便，常用这种说法。例如：Its eight thirty. 八点三十分。三、年、月、日表达法年、月、日表达法年份用基数词表示，一般写为阿拉伯数字读时可以以hundred为单位也可以以世纪、年代为单位分别来读在哪个月用介词in加月份词表示日期用定冠词the加序数词表示。在哪一天要用介词on 思维导图记知识点1） 年份用基数词表示，一般写为阿拉伯数字，读时可以以hundred为单位，也可以以世纪、年代为单位分别来读。如：1949 读作 n
