语法考点

数词

表示数目多少或顺序多少的词叫数词，数词分为基数词和序数词。表示数目多少的数词叫基数词；表示顺序的数词叫序数词。英语的数词可以作句子的主语、宾语、表语和定语。 1. 基数词 基数词的构成

规则 1—12的基数词是独立的单词 举例 one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve 特殊 13—19的基数词以-teen结尾 20—90的整十位均以-ty结尾 fourteen, seventeen sixty, ninety 13，15，18较特殊：13—thirteen 15—fifteen, 18—eighteen 20, 30, 40, 50, 80较特殊： 20—twenty, 30—thirty, 40—forty 50—fifty , 80—eighty 十位数与个位数之间要加连字符28—twenty-eight, 号―—‖ 96—ninety-six 百位和十位之间加and 148—one hundred and 若无十位则和个位之间加and forty-eight hundred（百），thousand（千）million（百万）， billion（十亿） three hundred, seven thousand, four million, eight billion hundred, thousand, million用复数形式修饰名词时要用―of＋复数名词‖ 巧记口诀

巧记 100 以内的基数词

基数词，不难记，找清规律很容易，十二以内词各异； 十三数到十九去，后加 -teen，莫忘记； 二十三十至九十，整十之后有 -ty / ti /； 要说基数―几十几‖，连字符号―-‖别丢弃； a hundred 是―一百‖，请你记住别大意。

2）以-ve结尾的改为ve为-f再加th。如：five—fifth

3）以-ty结尾的改为ty为-tie再加th。如：twenty—twentieth 4）熟记特殊词。如：one—first，two—second，three—third 注意：

(1) 两位以上的序数词仅个位数部分用序数词，其余部分仍用基数词。 如：thirty-sixth

(2) 使用序数词时一般加定冠词the。 如：I'm in the third grade

(3) 序数词作―几分之几‖讲时，用复数形式。 如：1/5→one fifth

On the last day I made a big decision. I got up early and bought thirty-seven cards. I spent the whole day in my room, but I did not write a single card!
