英语3年中考2年模拟一轮专题复习学案 第四讲 数词 原卷
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、翻译中。
一、基数词和序数词的构成规则
思维导图记知识点
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。
one—first six—sixth eleven—eleventh
two—second seven—seventh twelve—twelfth
three—third eight—eighth thirteen—thirteenth
four—fourth nine—ninth twenty—twentieth
five—fifth ten—tenth twenty-one—twenty-first
thirty—thirtieth
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
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：
It’s 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：
It’s twenty-nine to eight. 八点差二十九分。
It’s 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：
It’s eight thirty. 八点三十分。
三、年、月、日表达法?
思维导图记知识点
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 nineteen hundred and forty-nine 或 nineteen forty-nine；2000读作twenty hundred，或two thousand。
表示在哪一年，一般在年份前加介词in，使用year时，year放在数词之前。如：in the year two fifty-three B.C. 在公元前253年。但是，通常采用in加表示年份的阿拉伯数字。
2）在哪个月用介词in加月份词表示。例如：in May在五月。
3）日期用定冠词the加序数词表示。在哪一天要用介词on。例如：
National Day is on Oct. 1. (=National Day is on the 1st of October．) 国庆节是十月一日。
4）美国英语的月份在日期前面, 如：2008年8月3日表达为August 3, 2008；英国英语的习惯是日在月前, 如：3 August 2008或3rd August 2008.
四、电话号码及编号。
编号既可以用序数词，也可用基数词。例如：? the first lesson -- Lesson One 第一课?
the fiftieth page?-- page 50第五十页?
有的编号习惯上常用基数词。例如：? Room 829 (读作eight two nine) 829号房间 ?
Tel. No. 2793586 (读作Telephone number two seven nine three five eight six)
五、分数的表达法
分数由基数词和序数词合成。分子用基数词，分母用序数词。分子是1 时，分母用单数形式；分子大于1时，分母用复数形式。例如：1/3 → one third；2/3 → two thirds
六、加减乘除表示法。
思维导图记知识点
1)“加”用plus，and或add表示；“等于”用is，make，equal等词表示。
1+2=? 可表示为：How much is one plus two?
If we add one to/and two, we get three．一加二等于三。
2）“减”用 minus表示。
10－6＝? How much is ten minus six?
Take six from ten and the remainder is four. 十减去六等于四。
3） “乘”用time（动词）或multiply表示。
3X7＝? How much is three times seven?
Three multiplied by seven makes twenty-one．三乘以七等于二十一。
4） “除”用divide的过去分词形式表示。
12 ÷ 4=? How much is twelve divided by four?
Twelve divided by four equals/gives/makes three．十二除以四等于三。
考点一：基数词和序数词的用法
典例1：（2018甘肃白银 武威）22. The number “23,456”can be read as “________”.
A. twenty-three thousand, four hundred and fifty-six
B. twenty-three thousand and four hundred fifty-six
C. two three thousand and four five six
D. two three thousand, four and five six
【答案】A
【解析】句意：数字23456可以读作二万三千四百五十六。首先，英语数字都是以1000为单位的，thousand(千)，million(百万)，billion(十亿)所以从右向左三位三位的用逗号断开。百位和十位之间用and相连，个位和十位之间加连字符。故答案选A。在英语中，数字的读法是：从数字的右端向左端数起，每三位数加一个逗号，第一个逗号前面的数字后添加 thousand，第二个逗号前面的数字后添加 million，第三个逗号前面的数字后添加 billion，以此类推，两个逗号之间最大的数为百位数形式。另外，百位和十位之间用and连接，十位和个位之间用连字符“-”连接，而且具体数字和数量单位名词连用时数量单位名词不可使用复数。所以本题23456，应读作twenty-three thousand, four hundred and fifty-six，故答案选A。
举一反三

【解析】句意：我的祖父母居住在五层的旧公寓里，他们在三楼。第一空表示数量，故用基数词five；第二空表示次序用序数词，on the third floor意为“在三楼”。
【答案】D

A. Two fifths; are B. Second fifths; are C. Two fifths; is
【答案】A
【解析】考查分数用法及主谓一致。句意：我们班五分之二的学生打算下周去北京夏令营。分数表示：分子用基数词，分母用序数词，分子大于一时，分母加s。第一个空格处五分之二表示成two fifths，所以排除B；句中谓语动词随主语的单复数而变化，本句主语Two fifths of the students为复数名词，故选A。

A. twenty-three thousand, four hundred and fifty-six
B. twenty-three thousand and four hundred fifty-six

【答案】A
【解析】句意：数字23456可以读作二万三千四百五十六。首先，英语数字都是以1000为单位的，thousand(千)，million(百万)，billion(十亿)所以从右向左三位三位的用逗号断开。百位和十位之间用and相连，个位和十位之间加连字符。故答案选A。在英语中，数字的读法是：从数字的右端向左端数起，每三位数加一个逗号，第一个逗号前面的数字后添加 thousand，第二个逗号前面的数字后添加 million，第三个逗号前面的数字后添加 billion，以此类推，两个逗号之间最大的数为百位数形式。另外，百位和十位之间用and连接，十位和个位之间用连字符“-”连接，而且具体数字和数量单位名词连用时数量单位名词不可使用复数。所以本题23456，应读作twenty-three thousand, four hundred and fifty-six，故答案选A。

A. twenty-three thousand, four hundred and fifty-six
B. twenty-three thousand and four hundred fifty-six
C. two three thousand and four five six
D. two three thousand, four and five six
【答案】A
【解析】句意：数字23456可以读作二万三千四百五十六。首先，英语数字都是以1000为单位的，thousand(千)，million(百万)，billion(十亿)所以从右向左三位三位的用逗号断开。百位和十位之间用and相连，个位和十位之间加连字符。故答案选A。在英语中，数字的读法是：从数字的右端向左端数起，每三位数加一个逗号，第一个逗号前面的数字后添加 thousand，第二个逗号前面的数字后添加 million，第三个逗号前面的数字后添加 billion，以此类推，两个逗号之间最大的数为百位数形式。另外，百位和十位之间用and连接，十位和个位之间用连字符“-”连接，而且具体数字和数量单位名词连用时数量单位名词不可使用复数。所以本题23456，应读作twenty-three thousand, four hundred and fifty-six，故答案选A。
