考点：考查数词的用法
8．C

12．C
解析：C
【解析】句意：近三分之二的美国孩子从兼职工作中得到钱。分数是由基数词和序数词一起来表示的。基数词作分子，序数词作分母，除了分子是“1”以外，其它情况下序数词都要用复数形式。故答案为C。
13．A
解析：A
【解析】
句意：我们班五分之二的学生打算下周去北京参加夏令营。分子大于1时，做分母的序数词用复数，因此五分之二的表达应该是 two fifths，排除B,D；分数后面的名词为复数名词students，根据主谓一致的原则，只能用are，故答案选 A。
点睛：本题考查的知识点有分数的表达和主谓一致，一般情况下，表示分数时，分子要用基数词，分母要用序数词，如果分子大于1，表示分母的序数词要用复数形式，如：two thirds 三分之二。由“分数或百分数+名词”构成的短语作主语时，其谓语动词的数要根据短语中后面名词的数而定。如：60% of the students in our class are girls. 我们班60%的学生是女生。Two thirds of the apple is red.这个苹果的三分之二是红色的。
14．D

16．A
解析：A
【解析】句意：我们班五分之二的学生将要去下周在北京的夏令营。分数的表达方式是：用基数词+序数词表示，如果分子大于1,分母则要用复数形式，所以Two-fifths是正确的表达方式，分数引导的短语作主语，其谓语动词的数应根据分数后面的名词students来确定。所以选用be动词的复数形式，故选A。
点睛：全面总结一下分数的表达方式：首先，分数是由基数词和序数词构成——分子用基数词，分母用序数词，分子超过“1”时，分母用复数。1/4 可写作a [one] fourth，也可写作 a [one] quarter，分数引导的短语作主语，其谓语动词的数应根据分数后面的名词来确定。17．B
解析：B
【解析】
--你的周末怎么样？--很棒！它是我祖父的九十岁生日。他出生在二十世纪二十年代。one’s
+序数词+birthday，表示某人多少岁生日，ninetieth第九十；在表示在多少世纪多少年代时，经常用in +世纪+整十+s，所以二十世纪二十年代可以表示为：in the 1920s.结合句意，故选B。
18．A
解析：A
【解析】
句意：直到杨小姐告诉我那件事，我才知道她五十岁。考查数词辨析。英语中一般直接用基数词表示年龄，不用序数词，可排除C项。用“基数词+ years old”表示年龄时，注意years是复数形式，而“基数词—year—old”相当于形容词，year用单数形式。根据句意语境，可知选A。
19．B
解析：B
【解析】
【分析】
【详解】
句意：今天是我妹妹的九岁生日。我的家人会聚在一起庆祝。nine九，基数词； ninth 第九，序数词；表示某人的第几个生日用序数词，前面有名词所有格，不加定冠词the。根据题意，故选B。
20．C
解析：C
【解析】
【详解】
句意：这四个数中哪一个最大？——三分之二。考查分数的表达法。在英语中分数的表达法为：分子用基数词，分母用序数词，当分子大于一时，分母用复数形式；A. One third三分之一；B. A half一半、二分之一；C. Two thirds三分之二；D. A quarter四分之一。四个数相比较，可知三分之二最大，故答案选C。
21．C
解析：C
【解析】
试题分析：句意：--好消息，我们将有一个三天的假期。---我已经听说了，但是它在三天后才到。a three-day holiday中，.three-day是复合形容词作定语，表示为期三天的。例如：一名10岁的男孩，a ten-year boy。in three days和in three days' time意思一样，但它们不是三天之“内”的意思，而是三天以后的意思。例如：I’ll come back in three days.表达的意思我在三天后回来。因此选择C。
考点：考查数词的用法
22．B
解析：B
【解析】
【分析】
【详解】
考查数词，句意：“-嗨，杰克！放学后踢足球怎么样？-我很乐意，但今天是我祖父的九十岁生日，我们要庆祝一下。”，表示某人多少岁的生日，应该用序数词，第九十Ninetieth，故选B。
23．A
解析：A
【解析】
句意：——Mr Black看起来非常地激动。——是的，90%的学生已经来参加他的70岁的生日聚会。根据语境可知用现在完成，其结构是have done的形式，主语是复数，这里用have；表示某人的第几个生日用序数词，his seventieth birthday他的第70岁生日。故选A。
24．D
解析：D
【解析】
句意：﹣﹣妈妈，我四分之三的同学都戴眼镜。﹣﹣哦，天啊，你得好好保护你的眼睛。分数的表达法为：分子基数词，分母序数词，分子大于一，分母加s，所以四分之三的表达方法为three﹣fourths。分数作主语时，其后的谓语动词的单复数取决于它所修饰的名词，此处的classmates是可数名词复数形式，所以第二个空缺处应用动词的非第三人称单数形式wear，故选D。
25．B
解析：B
【解析】
句意：——那座大桥多长？——大约两千米长。thousand千，有数词修饰时，不加s。two thousand修饰meter，故meter用复数形式，故选B。

数词 （一）分类：数词有基数词和序数词两种。可以作句子的主语、宾语、表语和定语。 1、基数词：表示数目的词叫基数词。 常用的基数词有：
[注]：(1)百位与十位之间要加and；百位为0的话，就加在百位和个位之间。 108→one hundred and eight, 146→one hundred and forty-six, 500→five hundred , 1001→one thousand and one, 1813→one thousand eight hundred and thirteen. 一千：1000→one(a)thousand, 一万：10,000→ten thousand, 十万：100,000→one hundred thousand , 百万：1,000,000→one million, 千万：10,000,000→ten million, 亿：100,000,000→one hundred million, (2)英语用千、百万等单位计数，大数字从右向左看, 每隔三位划一逗号，倒数第一个逗号之前要用thousand，倒数第二个逗号之前要用million，倒数第三的逗号之前要用billion 表示。 3，456，789 three million four hundred and fifty- six thousand seven hundred and eighty-nine 6，004，001 six million four thousand and one (3) hundred、 thousand、 million表示确切的数时，不加s。如：five hundred(五百)，加S时表示不确定的数，后面必须要有of，前面可以加上some, many, several等词，翻译为：“成…上…”。hundreds of(成百上千的)，thousands of(成千上万的), millions of(成百万的) 2、序数词：表示顺序的数词叫序数词。 ①英语的序数词基本变法： (1) 一般在基数词后加th,(2)-ve结尾的改为-fth,(3)-ty结尾的改为-tieth,(4) 熟记特殊词。
初中英语知识点总结数词知识点总结 初中英语知识点总结:数词知识点总结数词分为基数词与序数词两类，表示数量多少得数词就是基数词,如ｏne(一），ｔwo（二），sｅｖen(七)等，表示顺序次第得数词叫序数词，如the fｉrsｔ（第一),the secoｎd(第二），the ｓeventh(第七). 在对数词进行复习得时候,同学们首先要会读会写所有基数词与序数词,以及与数词有关得时间表达法。对数词得考查，中考常采用单选题及听力题. （一)、序数词一般由基数词加th 构成 (二)、序数词得构成及用法： １、以下几个序数词较为特殊： fｉrst(第一)ｓeｃonｄ（第二)ｔhirｄ(第三)fiftｈ（第五) ｅiｇhth（第八）ｎｉｎｔh(第九)twelｆｔh（第十二） 2、以tｙ结尾得基数词变为序数词得构成方法就是：先将十位整数得基数词尾得-ｔｙ变成-tｉ，然后再加eｔh、 如：ｔｗenty twentiｅth（第二十) eigｈtｙeｉghtｉｅth（第八十） ３、基数词几十几变成序数词时,仅将个位数变成序数词，十位不变。 如：thirtytwo ｔｈirｔysecｏｎｄ(第三十二) sevenｔy－fｉve sｅveｎty-fifｔh（第七十五） 4、序数词得缩写形式，在阿拉伯数字后加上序数词得最后两个字母构成。 如：fifｔh ５th ｓecond ２nd 5、序数词前通常要用定冠词the。
６、ｈｕndｒed,thｏusand，ｍillioｎ,biｌｌion 等词在构成具体得数字时用单数形式。只有在表达笼统得多数时才加s，构成复数形式,前面不能加具体得数字。 如：three hundｒed seａts 三百个座位 ｈundｒedｓｏf 数以百计得,成百上千得thouｓａnds of 数以千计得，成千上万得 ｍillｉoｎｓｏf 数百万得billｉｏns ｏf 数十亿得 （三)与数词有关得时间表达法： 1、钟点表示法: ①顺读法 如：1:１5 one fｉfteen 3：30 thｒee ｔhｉrty ②倒读法(用pａsｔ/ｔｏ表示） 如:１:１5 ａｑuａｒｔer pａst one ３:30 half ｐａst threｅ 7：５6 ｆoｕr to eight ③表示钟点只用基数词,并且钟点前用介词at. 2、日期表示法： ①英语中日期得排列顺序就是：星期、月、日、年 如：20１６年3 月１7 日,星期一 Moｎday，Marcｈｔhe 17th，2０16、 ②在具体某一天前用介词oｎ 3、世纪、年代表示法

英语------数词 ▲掌握分数、时间、日期的表达法。 【复习要点】 （一）基数词 1 one 11 eleven 100 a hundred 2 two 12 twelve 20 twenty 1000 a thousand 3 three 13 thirteen 30 thirty 1，000，000 a million 4 four 14 fourteen 40 forty 10，000，000 ten million 5 five 15 fifteen 50 fifty 100，000，000 a hundred million 6 six 16 sixteen 60 sixty 1，000，000，000 a billion 7 seven 17 seventeen 70 seventy 8 eight 18 eighteen 80 eighty 9 nine 19 nineteen 90 ninety 10 ten 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one。 4．101—999的基数词先写百位数，后加and再写十位数和个位数。如：691 six hundred and ninety-one。 5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。6．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如： 888，000，000读作：eight hundred and eighty-eight million。 基数词的用法： 1. 基数词在句中的作用 基数词的作用相当于名词和形容词，在句中可作定语、主语、宾语（介宾）、表语、同
数词讲解专项练习 1 数词的讲解 一、定义：表示数目或顺序 二、分类：分为基数词和序数词两种。表示数目或数量多少的词叫基数词；表示数目顺序的词叫序数词。 三、基数词的构成： 1）1-12的基数词是独立的单词，即：one ，two ，three ，four ，five ，six ，seven ，eight ，nine ，ten ，eleven ，twelve 。 2）13-19的基数词以-teen 结尾。如：fourteen ，seventeen 等，但13，15，18较特殊，13—thirteen, 15—fifteen, 18—eighteen 。 3）20-90的整十位均以-ty 结尾。如：sixty ，ninety ，但20，30，40，50，80较特殊，20—twenty, 30—thirty, 40—forty, 50—fifty, 80—eighty 。 4）十位数与个位数之间要加连字符号"-" ，如：28-twenty-eight ，96-ninety-six 。 5）百位和十位（若无十位则和个位）之间加and ，如： 148—one hundred and forty-eight 406—four hundred and six 6）hundred （百），thousand （千），million （百万），billion （十亿）等前面即使有具体的数词，several, some, many也不能在它们的后面加-s 。如：six hundred，eight million。如果表示不确定数目时，用hundreds of /thousands of /millions of /billions of +名词复数, 前面不能再加数字。 7）1000以上的数字，从后往前数每三位加一个逗号" ，" 第一个逗号前为千（thousand ），第二个逗号前为百万（million ），第三个逗号前为billion （十亿）。英语中无“万”这个词，我们可以用" 几十个千（thousand ）" 表示几万，" 几百个千（thousand ）" 表示" 几十万" 。如：2，510＝two thousand five hundred and ten 84，296＝eighty-four thousand two hundred and ninety-six 274，350＝two hundred and seventy-four thousand three hundred and fifty。 四、序数词的构成： 1）序数词一般是以与之相应的基数词尾加-th 构成，如：fourth, tenth, 但以下的这些基数词变为序数词时，有特别之处。 One —first, two —second, three —third, five—fifth, nine —ninth, twelve —twelfth 2）以_ty 结尾的单词，要先变y 为i, 在加-eth. 。如：thirty —thirtieth, fifty—fiftieth 3）以one, two, three 等结尾的多位数词，要将个位数变成序数词。如： twenty-one —twenty-first, one hundred and one—one hundred and first 注意：序数词前常用定冠词，有时还可以用不定冠词a/an 则表示" 又一" 的意思。（没有具体范围的限制）如： Mr. Brown has a second car. 布朗先生另外还有一辆车。 He has tried a second time. 他又尝试了一次。 五、数词的应用 1)时刻的表示:小时、点钟、分钟、秒钟要用基数词。 ①“几点钟”用基数词加o'clock 。o'clock 可省略。如:5点钟-five (o'clock ) ②“几点过几 分” , ≤30分钟" 用介词past 。如: 7:15— fifteen/ a quarter past seven 7:30— half past seven
