专题二 数词、冠词
一.数词
1.数词概述：表示数目多少或顺序先后的词叫做数词。其用法相当于名词或者形容词。
2.数词的种类：可以分为两种： 基数词：表示数目多少的数词。序数词：表示先后顺序的数词。
3.基数词的写法和用法
1)1—12的基数词是独立的单词，即： one，two，three，four，five，six，seven，eight， nine，ten，eleven，twelve。
2)13—19的基数词以-teen结尾。如：14—fourteen，但13，15，18较特殊，13—thirteen 15—fifteen 18—eighteen。
3)20—90的整十位均以-ty结尾。如：60—sixty，但20，30，40，50，80较特殊， 20—twenty 30—thirty 40—forty 50—fifty 80—eighty。
4) 十位数与个位数之间要加连字符号“-”，如：28—twenty-eight，96—ninety-six。
5) 百位和十位(若无十位则和个位)之间加“and”，如：148—one hundred and forty-eight , 406—four hundred and six。
6) hundred(百)，thousand(千)，million(百万)，billion(十亿)等前面即使有具体的数词，也不能在它们的后面加s。
7) .百(hundred),千(thousand),百万(million)等词与介词of连用的时侯，用复数形式，表不确定数目，其前面不可与数字连用
8).表示“几十”的数词，复数形式可用来表示人的岁数或年代。
如： He is in his forties. 他四十多岁。
This took place in the 1930s. 这事发生在二十世纪三十年代。
9).基数词可与其他词构成形容词。
如： Can you say something about your two-month holiday? ?(two和month之间有连字符时，month用单数)
4. 序数词的写法和用法
1).基数词变序数词可利用口诀巧记：“一、二、三，特殊记，八去“t ”，九去“e”，“ve”要用“f”替，见“y”变成“i”和“e”，词尾加上“th”，若是遇到几十几，只变个位就可以。”
变法如下：first，second，third，eight—eighth nine—ninth，five—fifth，twelve—twelfth，twenty—twentieth，forty—fortieth，twenty-five—twenty-fifth。
其余情况均在基数词后加th。如： six—sixth, nineteen—nineteenth , hundred— hundredth, thousand—thousandth等。
2). 序数词前常用定冠词the, 表“顺序”。但如果序数词不表示顺序，而表示“又一个，另一个”时，则不能用the, 要用a. 如：Try it a second time. 再试一下。
5. 序数词表示“名次”时，不用定冠词。
He was first. 他得了第一名。
Who was first? Who was second?谁是第一名?谁是第二名?
注意:
1.分数的读法：分子必须用基数词，分母用序数词。分子如果大于1，分母须用复数形式。先读分子，再读分母。分子为one时可换用a. 如：
In our class, about a third can speak English well.
Two thirds 三分之二。
2.1/2读作“a(或one)half(而不是a second “一秒钟”)，1/4既可读作“a(或one)quarter”又可读作 “a(或one)fourth”.
3/4:Three quarters
3.小数的读法：小数点的前的基数词与前面所讲的基数词读法完全相同;小数点读作point,小数点后只须将数字一一读出。
15.67 读作: fifteen point six seven
4. 百分数的读法：先读基数词，再读百分号 “%”(读作percent).
5% 读作: five percent.
5.年代的读法为“两位，两位”地读。整百的后读hundred,整千的后读thousand, 前常加 the year. 如：
1937读作nineteen thirty-seven 或：nineteen hundred and thirty-seven
2000 年 读作 the year two thousand
December the first, nineteen ninety-four 一九九四年十二月一日
二.冠词
1. 冠词概述：冠词是虚词，本身不能单独使用，也没有词义，它用在名词的前面，帮助指明名词的含义。
2. 冠词的种类：英语中的冠词有三种，一种是定冠词，另一种是不定冠词，还有一种是零冠词。
3. 不定冠词的用法
