2019-2020学年中考英语语法备考04 数词(讲解)(含答案)
2019-2020学年中考英语语法备考秘籍—数词【分析解读】数词为中考考点，但是考频不高。
主要考点为基数词、序数词分数以及hunfred/thousand/million的用法这些用法具有固定性，所以才用的记忆方法比较好。
【知识方法】基数词的用法序数词的用法年代表达法日期表达法数词分数的表答法小数的表达法百分数的表达法倍数的表达法知识清单数词英语数词表示数目或者顺序，可分为基数词和序数词。
基数词表示数量，序数词表示顺序。
知识梳理：提纲挈领，抓住重点和难点！1. 基数词的构成注意：(1)基数词1-12是独立单词，需逐个记忆。
(2)基数词13-19是在个位数词的词干后加-teen构成，其中thirteen,fifteen,eighteen变化不规则。
(3)基数词20-90的整十数除twenty,thirty,forty,fifty, eighty为特殊形式外是在个位数词后面加-ty构成。
基数词21-99的非整十数是在十位数词后面加上个位数词构成，中间加上连字符“-”。
如21 twenty-one2.基数词的读法(1)在读三位数或三位数以上的基数词时，需在十位数之前（若十位数是“0”，在个位前）加连词and。
304-three hundred and four1,342-one thousand,three hundred and forty-two(2)阿拉伯数字每三位数就需用一个逗号隔开，从后往前数；所用的英语单词为：thousand(千）,million(百万）,billion(十亿）,英语中没有“万”和“亿”，在表示“万”和“亿”时要按十进位法来推算。
1万可用10千来表示，即10,000。
100,000,000可写成a hundred million。
35,845可写成thirty-five thousand,eight hundred3.基数词的基本用法4.hundred,thousand,million与billion的用法(1)与具体数词one,two…或several,some,many等车用时，要用单数形式。
