考點一:確切數量與模糊數量表示法
●當hundred, thousand, million等前面有不定冠詞a或one, two, three, four等數詞時,hundred, thousand, million等要用單數形式表示“確切數量”。如果表示“數百、數千、數百萬”等“模糊數量”時,hundred, thousand, million要用復數形式,且后面要與of連用。如:a hundred people“一百人”,four thousand cars“4000輛車”,seven million dollars“700萬美元”,hundreds of computers“數百臺電腦”,thousands of trees“數千棵樹/成千上萬棵樹”,millions of stars“數百萬顆星星”等。
●表示“模糊數量”時,還可用and連接兩個數詞hundred, thousand或million, 此時這兩個數詞都要用復數形式,后面同樣都要與of連用。如:hundreds and thousands of“千千萬萬的”,hundreds and millions of“億萬的”等。

考點三:分數詞表示法
分數詞由“基數詞+序數詞”構成,基數詞表示“分子”,序數詞表示“分母”。當“分子”大于1時,“分母”要用復數形式。比較:one third三分之一,two thirds三分之二,three fifths五分之三,four sevenths七分之四。
●構成分數詞時,基數詞與序數詞之間加不加橫線都可以。如:one-third=one third,three-fifths=three fifths。
●“數詞/冠詞a+quarter”表示“四分之……”,quarter表示“分母”,相當于“數詞+fourth(s)”。當“分子”大于1時,quarter要用復數形式。如:one/a quarter=one fourth“四分之一”;three quarters=three fourths“四分之三”等。
●表示“百分之……”的percent或per cent不用復數形式,構成形式:“基數詞+percent/per cent”。如:one percent/per cent“百分之一”,twenty-six percent/per cent“百分之二十六”等。

—That’s ______ of the world’s total.
A. two third B. two-third
C. two thirds D. two three
【答案】 C
重要補充
1.
考查分數詞用法的試題,還常結合主謂一致進行考查。此時,我們要依照分數詞所修飾的名詞來確定句子的謂語用單數還是用復數。如果所修飾的是復數形式的可數名詞,謂語要用復數形式;如果所修飾的是不可數名詞,謂語要用單數形式。比較例句:
One third of the people there are farmers.那里三分之一的人是農民。
Two thirds of the work has been done.這項工作的三分之二已經完成。
2.
population (人口)要用單數形式,但表示“百分之幾的人口”作主語時,謂語動詞卻要用復數形式。如:
Over 80 per cent of our whole population are peasants.我國總人口的百分之八十以上是農民。
Twenty percent were dropped in the examination.有百分之二十的人考試不及格。

考點五:基數詞與序數詞辨異
●表示人或物的“數量”,要用基數詞。如:five students“五個學生”,one hundred computers“一百臺電腦”。
●表示“第幾”要用序數詞,前面要與the或人稱代詞所有格連用。例如:the First World War“第一次世界大戰”,the third flood“第三層樓”,in her second class“在她的第二節課上”。
●“a/an+序數詞”不是強調“第幾”,而是表示“又一、另一、再一”。例如:a second Lei Feng“又一個活雷鋒”,a third time“再次”。
