2017英語語法專題
  2017英語語法專題: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:可以分爲兩種: 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。分子爲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.年代的讀法爲“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
