中考数词考点梳理

 一、考查数词表示编号

    在通常情况下，表示年级、班、行、房间、课的编号要用基数词，且位于词首的字母要大写，基数词居后(若用英语表示，其首字母也要大写)；若要用序数词表示，则序数词必须加上the。如：

    Lesson One/ The first lesson (第1课)，Room 306 (306号房间)，Row Four/ The fourth row

(第4排)，Class Three Grade Nine (九年级三班)

    二、考查基数词的在拼写

    对基数词的拼写须注意：⑴1—20应当逐个记忆，21—99应是说整十加上连字符“-”然后再说几。如：78→seventy-eight ⑵ 百位与十位或个位之间应加and。如：675→six hundred and seventy-five。⑶若是四位和四位以上的数，则是从后面向前数，每三位为一组，用逗号分开，第一个逗号前是“千”(thousand)，第二个逗号前则是“百万”(million)，第三个逗号前则是“ 十亿”(billion)。如：7,258,369,000→seven billion，two hundred and fifty-eight million，three hundred and sixty-nine thousand。

    三、考查基数词hundred/thousand/million/billion的单复数形式

    当hundred/thousand/million/billion与two/three等数字连用表示确定数目时，这类数词需用单数形式；当此类基数词用来表达不确定数目时，即数百、数千等意思时，要用“hundreds／thousands／millions／billions + of +复数名词”表达，其中of不可少，此时hundred之类基数词前面不可用具体数字修饰，但可加many/several。试比较：

      five hundred students             (√)

      five hundreds students            (×)

      ten thousands of students          (×)

many/several thousands of students  (√)

四、考查-ty结尾的基数词的复数意义

从20至90以-ty结尾的基数词当用来表示年代或岁数时，此时要出复数形式出现。如： in the1990s/in the1990’s在二十世纪九十年代  in his/her forties在他/她四十多岁时

注意：在“基数词-单数名词-形容词”所构成的复合形容词中，其中名词要用单数形式。如：

一个十二岁的男孩→a twelve-year-old boy

一座800米长的桥→an 800-metre-long bridge

女子400米接力→girls’ 400-metre relay race

    五、考查序数词的构成与功能

    序数词除用来表示编号外，还可用来表示事物的先后顺序，此时序数词多与定冠词the、物主代词或名词所有格等连用。对序数词的考查常见于序数词的拼写以及与基数词的词形转换中。应关注下列数词的拼写与转换：

one→first, two→second, three→third；eight→eighth；nine→ninth；five→fifth, twelve→twelfth；twenty→twentieth, forty→fortieth；twenty-one→twenty-first, fifty-nine→fifty-ninth

    六、考查不定冠词a/an与序数词连用

序数词除了与定冠词the、物主代词或名词所有格等连用以表示顺序外，不定冠词a／an也能与序数词连用，可表达一种特殊功能，意为“再一”、“又一”，相当于another。如：

Then they had a second child—a son.后来他们又有了一个孩子---- 一个儿子。

    七、考查分数词的构成以及当其作主语时谓语动词的单复数

1. 分数词的一般构成：分子用基数词，分母用序数词；除分子是“1”的情况外，序数词都用复数。如： 1／3 →a(one) third，2／3 →two-thirds， 2／5→two-fifths。

注意：1／2 →one half或a half（但不说one second），1／4 → a(one) fourth/quarter，3／4 → three-quarters/fourths

    2. 分数词作主语时，谓语动词的单复数应由of后面名词的数确定：of后面的名词为可数复数名词时，谓语动词用复数形式；of后面的名词为不可数名词时，谓语动词用单数形式。试比较：

    Three-fifths of the work is hard to finish.五分之三的工作很难完成。

Three-fifths of the students in our class are League members.我们班五分之三的学生是共青团员。

注意：数词作主语时，谓语动词多使用单数形式。如：What’s two and/plus three?

八、考查时间的表达法

1. 整点钟：基数词+o’clock。

2. 非整点时间：顺读（先说点钟，再说分钟）或逆读：

⑴当分钟数小于或等于30时，可用“分钟+past+点钟”表示。如：7：25 twenty-five past seven

⑵当钟点数大于30时，可用“（60―分钟）+to +（点钟+1）”表示。如：7：35 twenty-five to eight(60―35=25) (7+1=8)

注意：15 minutes = a quarter 30 minutes = half

九、考查特殊短语的表达

我们需要掌握以下短语的常见表达：半个小时→half an hour, 一天半→one and a half days或one(a) day and a half, —、二天→one or two days或one day or two, 三、五次→three or five times。

注意：后面两个短语中的or不可用and代替。
