2019中考英语语法精讲精练及答案：数词
一、提分关键
1. 掌握基数词变序数词的规律
基变序，有规律，末尾加上-th。 一、二、三特殊记，面目全非要注意。
八加h, 九去e, ve要用f 替。 逢十改y 为ie, 后跟-th 莫忘记。
若想表示几十几，只变个位就可以。
2. 牢记百、千、百万的用法
表示具体数目时，hundred, thousand, million 用单数形式；但是表示“数百”、“数千”、“数百万”等不确切数目时，hundred, thousand, million要用复数形式，且后接of短语。
3. 熟知分数的表达
1） 分子用基数词，分母用序数词，当分子大于1时，分母加s,
2） 几个常用表达法: a half 1/2; a quarter 1/4; three quarters 3/4
4. 理清数词特殊用法
1). 序数词前一般加定冠词the, 当序数词前加a/an 时，表示“再一；又一”
2). 数词与数量单位、形容词构成复合形容词作定语时，定语成分中名词用单数形式。
a two—week holiday. 一个两周的假期。
