高中英语语法考点纵览第四章数词一、概述数词是表示数目多少或顺序先后的词。
由定义进而将数词分为两类:基数词和序数词,前者表示数目的多少,后者表示顺序的先后。
本章首先概述了数词的定义,进而从定义出发,将数词分为基数词和序数词两大类,接着以基数词和序数词分类阐述了数词在句中的作用,然后,以两大类数词为纲,分别介绍了两大数词的用法(包括表示法、特殊用法等)可谓内容详实。
最后介绍倍数的表示法(包含倍数的表达、含义及表达法之间的区别)。
为了使本章内容更加全面充实,最后介绍了一下特殊数的表达法。
本章末尾对数词进行了归纳、提炼并提出学好数词的“点金术”。
此章内容比较简单,线索比较清晰,学起来应该比较容易,关键要把握特殊的含义及用法。
相信,在把握好线索,全面了解掌握含义及用法的基础上定能对数词有全新的认识。
二、定义及分类表示数目多少或顺序先后的词,叫做数词。
数词与不定动词很相似,其用法相当于名词或形容词。
数词可以分为两种:表示数目多少的词叫做基数词,表示顺序先后的词叫做序数词。
三、在句中的作用数词的用法相当于名词或形容词,所以在句子中数词能够充当名词和形容词所能充当的成分,如:主语、宾语、表语、同位语、定语、状语。
如:It is said that thirteen is an unlucky number.(基数词作主语)The first isn’t the best.(序数词作同位语)It is north two hundred.(基数词作宾语)He is among the first to get to the international airport.(序数词作表语)The visitors in this place of interest are about five thousand.(基数词作表语)Now, he has become the first in the race.(序数词作表语)We, four will look together to solve the problem.(基数词作同位语)Jim, the last, was scolded by his teacher.(序数词作同位语)The kind woman gave the boy five apples.(基数词作定语)I think he is the first person knowing the secret.(序数词作定语)It’s very dangerous to ride two or more.(基数词作状语)The company ranks first among the similar companies.(序数词作状语)四、两种基本数词的用法1、基数词的用法(1)基数词中的1—12是单个的独立的单词,13—19加后缀-teen构成的相应基数,20—90是由2—9加后缀-ty构成的相应基数。
