衔接点05 数词（讲义，全国通用）英语小升初衔接

衔接点05 数词（小初考点差异及衔接） 小学视角 初中展望 1.只学 0–100 基数词 2.1–20 序数词，仅限数量、顺序、基础时间表达 1.基数词的读写和应用； 2.序数词的读写和应用。 3.分数、小数、百分数及其他用法 衔接引导 小学阶段：小学阶段主要侧重认识基数词、序数词，掌握 0-100 数字认读、拼写与基础含义，结合数量、顺序、时间、号码等简单场景直接运用，依靠单词形式和字面意思答题。题目以基础识记类题型为主，考点简单直白。 常见题型为： ①按要求写出基数词、序数词。 ②用所给单词的正确形式填空。 ③选词填空。 ④单项选择题。 ⑤数字、短语英汉互译。 初中阶段：初中阶段要求系统掌握数词变形规则、语法搭配与各类特殊表达，能结合句式、上下文语境区分基数词和序数词，熟练运用大数、分数、年代、编号等拓展用法，考查形式更多样，出题灵活且易设置陷阱。主要的题型为： ①用所给单词的适当形式填空。 ②单项选择题（侧重易混用法辨析）。 ③句型转换、同义句改写。 ④句子改错。 ⑤短文填空、完形填空。 ⑥根据语境完成数字、句式表达。 小学数词考点梳理 数词的分类：数词分为基数词和序数词。基数词表示数目的多少。序数词表示事物的先后顺序，往往与定冠词the连用。 考点一 基数词 (1)0—12单独记。如： zero, one, two, three等。 (2)13—19的词尾都是teen。如：fourteen, seventeen等，但13—thirteen，15—fifteen，18—eighteen需要特殊记。 (3)20以上的整十的基数词均以ty结尾。 20—twenty，30—thirty，40—forty，50—fifty，80—eighty等。 (4)＂几十几＂要加连字符号＂-＂。 48—forty-eight, 97—ninety-seven等。 (5)＂几百几十＂或者＂几百几十几＂在＂百＂后加and。 156—one hundred and fifty-six, 509—five hundred and nine。 (6)四位数或者四位数以上的基数词的拼写规律：用逗号从右往左每三位加一个逗号，第一个逗号读作thousand(千)，第二个逗号读作million(百万)，第三个逗号读作billion(十亿)，hundred后莫忘＂and＂。 3,610＝three thousand six hundred and ten； 94,295＝ninety-four thousand two hundred and ninety-five； 基础用法 ①直接修饰可数名词，名词多用复数形式（数量＞1 时） 例：one book 一本书 ；two books 两本书 ②表达年龄 结构：主语 + be + 基数词 + (years old) 例：I am ten (years old). 我十岁了。 ③表达电话号码、门牌号、班级、编号 数字逐个读出即可：Room 301 → room three zero one ④简单算式表达 例：One and two is three. 一加二等于三。 考点二 序数词 表示顺序的词称为序数词。其形式如下: 基数词 序数词 缩写 中文 变化说明 one first 1st 第一 特殊变化 two second 2nd 第二 特殊变化 three third 3rd 第三 特殊变化 four fourth 4th 第四 直接 + th five fifth 5th 第五 ve 变 f+th six sixth 6th 第六 直接 + th seven seventh 7th 第七 直接 + th eight eighth 8th 第八 去 t+h nine ninth 9th 第九 去 e+th ten tenth 10th 第十 直接 + th eleven eleventh 11th 第十一 直接 + th twelve twelfth 12th 第十二 ve 变 f+th thirteen thirteenth 13th 第十三 直接 + th twenty twentieth 20th 第二十 整十：y 变 ie+th 2.从第二十至第九十九 整数第几十的形式由其对应的基数词改变结尾字母y为i,再加“-eth”构成。如: twenty—twentieth,thirty—thirtieth 表示第几十几时,用几十的基数词形式加上连字符“-”和个位序数词形式一起表示。如: thirty-first 第三十一 fifty-sixth 第五十六 seventy-third 第七十三 ninety-ninth 第九十九 3.第一百以上的多位序数词 由基数词的形式变结尾部分为序数词形式来表示。如: one hundred and twenty-first 第一百二十一 one thousand,three hundred and twentieth 第一千三百二十 4.序数词的缩写形式 有时,序数词可以用缩写形式来表示。主要缩写形式有: first—1st　second—2nd　third—3rd fourth—4th　sixth—6th　twentieth—20th twenty-third—23rd 5.序数词的句法功能 序数词在句中可作主语、宾语、定语和表语。如: The second is what I really need.第二个是我真正需要的。(作主语) He chose the second.他选了第二个。(作宾语) We are to carry out the first plan.我们将实施第一个计划。(作定语) She is the second in our class.在我们班她是第二名。(作表语) 另外,基数词也可以表示顺序。只需将基数词放在它所修饰的名词之后即可,不需要添加定冠词。如: the first lesson—Lesson 1 the fifth page—Page 5 the twenty-first room—Room 21 6.序数词基本用法 基本搭配：序数词前面通常加 the 例：the first student 第一名学生 常用场景 日期：June 1st 六月一日 楼层：the third floor 三楼 排名、顺序：He is the second. 他是第二名。 区分用法：表数量用基数词，表顺序用序数词 对比： I have three pens.（三支，数量→基数词） This is the third pen.（第三支，顺序→序数词） 即学即练习 1．—Do you know the height of the old building? —Yes. It’s about ________. A．50 meters long B．50-meter-long C．50 meters 【答案】C 【详解】句意：——你知道那座旧建筑的高度吗？——知道。大约50米。50 meters long50米长；50-meter-long50米长的（复合形容词，通常在名词前作定语，不能单独在句尾作表语）；50 meters50米。根据问句中的“height”可知，此处询问的是建筑的“高度”。A项表示长度，不合题意，排除；B项为复合定语，后面需要接名词，排除；C项作表语表示具体的高度度量，意为“大约50米”，符合逻辑。 2．Today is my sister’s ________ birthday, so there are ________ candles on the cake. A．twelfth, twelve B．twelve, twelve C．twelve, twelfth 【答案】A 【详解】句意：今天是我妹妹的十二岁生日，所以蛋糕上有十二根蜡烛。twelfth是序数词，意为“第十二”；twelve是基数词，意为“十二”。第一空，根据“my sister’s...birthday”可知，此处指“第十二个生日”，用序数词twelfth；第二空，根据“there are...candles on the cake”可知，此处指蛋糕上蜡烛的数量是“十二”，用基数词twelve。 3．________ people visited the exhibition about famous scientists last month. A．Million of B．Millions of C．Two millions D．Two millions of 【答案】B 【详解】句意：上个月数百万人参观了关于著名科学家的展览。million前面有具体数字时，用单数形式，后不加of；前面没有具体数字时，用复数形式，后加of，表示“数百万的”。本题空前无具体数字，表示概数，应用Millions of。 4．I’m very happy because today is my grandma’s ________ birthday. A．seventy B．the seventy C．the seventieth D．seventieth 【答案】D 【详解】句意：我非常高兴因为今天是我奶奶的七十岁生日。在描述某人的多少岁生日时，应该使用序数词来表示顺序，并且序数词前有名词所有格修饰时，序数词前不用定冠词“the”。“seventy”是基数词，表示数量；“seventieth”是序数词，表示顺序。所以这里应该用“seventieth”，并且前面不用加“the”。 5．We have _________ classes in the morning.

A．three-fifth; are B．three-fifth; is C．three-fifths; are D．three-fifths; is 【答案】C 【详解】句意：这里大约五分之三的警官年龄在30岁以下。  three-fifth五分之三（形式错误）；three-fifths五分之三（正确形式）；is用于单数主语；are用于复数主语。分数表达中，分子用基数词，分母用序数词，当分子大于1时，分母需加-s，故“五分之三”应为“three-fifths”；主语“About three-fifths of the police officers”中的中心词“officers”为复数，谓语动词应用“are”。 三、完成句子 26．数千人观看了现场直播。 ________ people watched the live broadcast. 【答案】Thousands of 【详解】原句关键词为“数千人”，thousands of表示“数以千计的；数千的”。 27．两根胡萝卜在书桌上。 ________ ________ are on the desk. 【答案】 Two carrots 【详解】原句中“两根胡萝卜”是关键名词，“两根”用two表示，句首大写；“胡萝卜”用carrot，因为前面有two修饰，应用名词复数carrots。故填Two；carrots。 28．今天是星期一，3月1日。   Today is Monday, ________ 1st. 【答案】March 【详解】原句中“3月”是关键词，表示“3月”的单词是March。月份是专有名词，首字母大写。故填March。 29．75 percent of the students passed the exam. (同义句转换) ________ ________ ________ the students passed the exam. 【答案】 Three fourths of 【详解】句意：75%的学生通过了考试。原句“75 percent of”表示“百分之七十五的”，同义表达可用“Three fourths of”表示“四分之三的”，因75%等于3/4，即四分之三，句首单词首字母大写。 30．Timo usually gets up at seven twenty.（改为同义句） Timo usually gets up at ________ ________ ________. 【答案】 twenty past seven 【详解】句意：蒂莫通常七点二十分起床。原句“seven twenty”采用的是直接读法（小时+分钟），意为7点20分。 英语中表达时间还可借助介词past。当分钟数在30分钟以内（含30分钟）时，结构为“分钟+past+小时”，意为“几点过几分”。故填twenty；past；seven。 31．数百万游客每年来参观这个瀑布。 ________ ________ tourists come to visit this waterfall every year. 【答案】 Millions of 【详解】原句中“数百万”是关键词，表示“数百万的”的短语是millions of。本句为一般现在时，短语millions of后接可数名词复数tourists，句首首字母大写。故填Millions；of。 32．尽管他的妈妈四十多岁了，她看起来还是非常年轻。 His mother looks pretty young even though she is ________ ________ ________. 【答案】 in her forties 【详解】原句中“四十多岁”是关键词，固定表达in one’s forties表示“在某人四十多岁时”，主语为his mother，对应物主代词用her。 33．他每周阅读五次。   He reads ________ ________ a week. 【答案】 five times 【详解】根据汉语提示可知，five times表示“五次”。 34．在20世纪20年代，它在上海流行起来。 ________ ________ ________, it became a fashion in Shanghai. 【答案】 In the 1920s 【详解】原句中“在20世纪20年代”是关键词，对应的英文表达是“In the 1920s”，在句中作时间状语。 35．许多潮水有两米高。 Many tides are ________ ________ ________. 【答案】 two metres high 【详解】原句中“两米高”是关键词，表示两米高的短语是“two metres high”。 【培优提升】 四、语法选择 阅读下面短文，按照句子结构的语法性和上下文连贯的要求，从所给的四个选项中选出一个最佳答案，使短文连贯完整。 My name is Mary.

They are our new books”，并没有杂乱的描写，说明课桌是整洁的，tidy（整洁的）符合语境；middle（中间的）、last（最后的）、welcome（受欢迎的）均与语境无关。 45．句意：你能看到上面有一些书。后文明确说明“They are our new books”，因此books（书）符合语境；watches（手表）、pencil boxes（铅笔盒）、pens（钢笔）均与后文描述不符。 五、选词填空 用方框中所给单词的适当形式填空，使短文完整正确。（每个单词限用一次，每空限填一个单词。） real  dumpling  be  mutton  we  great  can  fit  one  much Do you often eat in restaurants?

It’s about ________. A．50 meters long B．50-meter-long C．50 meters 2．Today is my sister’s ________ birthday, so there are ________ candles on the cake.
