專題二 數詞、冠詞
一.數詞
1.數詞概述：表示數目多少或順序先後的詞叫做數詞。其用法相當於名詞或者形容詞。
2.數詞的種類：可以分為兩種： 基數詞：表示數目多少的數詞。序數詞：表示先後順序的數詞。
3.基數詞的寫法和用法
1)1—12的基數詞是獨立的單詞，即： one，two，three，four，five，six，seven，eight， nine，ten，eleven，twelve。
2)13—19的基數詞以-teen結尾。如：14—fourteen，但13，15，18較特殊，13—thirteen 15—fifteen 18—eighteen。
3)20—90的整十位均以-ty結尾。如：60—sixty，但20，30，40，50，80較特殊， 20—twenty 30—thirty 40—forty 50—fifty 80—eighty。
4) 十位數與個位數之間要加連字符號「-」，如：28—twenty-eight，96—ninety-six。
5) 百位和十位(若無十位則和個位)之間加「and」，如：148—one hundred and forty-eight , 406—four hundred and six。
6) hundred(百)，thousand(千)，million(百萬)，billion(十億)等前面即使有具體的數詞，也不能在它們的後面加s。
7) .百(hundred),千(thousand),百萬(million)等詞與介詞of連用的時侯，用複數形式，表不確定數目，其前面不可與數字連用
8).表示「幾十」的數詞，複數形式可用來表示人的歲數或年代。
如： He is in his forties. 他四十多歲。
This took place in the 1930s. 這事發生在二十世紀三十年代。
9).基數詞可與其他詞構成形容詞。
如： Can you say something about your two-month holiday? ?(two和month之間有連字符時，month用單數)
4. 序數詞的寫法和用法
1).基數詞變序數詞可利用口訣巧記：「一、二、三，特殊記，八去「t 」，九去「e」，「ve」要用「f」替，見「y」變成「i」和「e」，詞尾加上「th」，若是遇到幾十幾，只變個位就可以。」
變法如下：first，second，third，eight—eighth nine—ninth，five—fifth，twelve—twelfth，twenty—twentieth，forty—fortieth，twenty-five—twenty-fifth。
其餘情況均在基數詞後加th。如： six—sixth, nineteen—nineteenth , hundred— hundredth, thousand—thousandth等。
2). 序數詞前常用定冠詞the, 表「順序」。但如果序數詞不表示順序，而表示「又一個，另一個」時，則不能用the, 要用a. 如：Try it a second time. 再試一下。
5. 序數詞表示「名次」時，不用定冠詞。
He was first. 他得了第一名。
Who was first? Who was second?誰是第一名?誰是第二名?
注意:
1.分數的讀法：分子必須用基數詞，分母用序數詞。分子如果大於1，分母須用複數形式。先讀分子，再讀分母。分子為one時可換用a. 如：
In our class, about a third can speak English well.
Two thirds 三分之二。
2.1/2讀作「a(或one)half(而不是a second 「一秒鐘」)，1/4既可讀作「a(或one)quarter」又可讀作 「a(或one)fourth」.
3/4:Three quarters
3.小數的讀法：小數點的前的基數詞與前面所講的基數詞讀法完全相同;小數點讀作point,小數點後只須將數字一一讀出。
15.67 讀作: fifteen point six seven
4. 百分數的讀法：先讀基數詞，再讀百分號 「%」(讀作percent).
5% 讀作: five percent.
5.年代的讀法為「兩位，兩位」地讀。整百的後讀hundred,整千的後讀thousand, 前常加 the year. 如：
1937讀作nineteen thirty-seven 或：nineteen hundred and thirty-seven
2000 年 讀作 the year two thousand
December the first, nineteen ninety-four 一九九四年十二月一日
二.冠詞
1. 冠詞概述：冠詞是虛詞，本身不能單獨使用，也沒有詞義，它用在名詞的前面，幫助指明名詞的含義。
2. 冠詞的種類：英語中的冠詞有三種，一種是定冠詞，另一種是不定冠詞，還有一種是零冠詞。
3. 不定冠詞的用法
不定冠詞a (an)與數詞one 同源，是"一個"的意思。a用於輔音音素前，一般讀作[e]，而an則用於元音音素前，一般讀做[en]。

A knife is a tool for cutting with.
