考情动态分析 2005年全国卷及各地14套题中对数词考查的比重较小，只有上海卷及湖北卷考查了数词。2006年只有两道题涉及到数词，主要以对倍数的表达方法及概数的考查为主。今后高考不会单纯考查数词，而会将其与主谓一致综合考查。 考点核心整合 一、数词分为基数词、序数词、分数、小数、概数和倍数。复习时要注意下面问题： (一)基数词的意义 表示事物数量的多少，特别是hundred,thousand,million等，前面若有基数词或某些表示数量的限定词时，它们只能用单数。基数词的复数形可表示泛指数词，如tens of people,hundreds of trees,millions of stars等。整十的数词的复数用于表示“几十岁”或“……年代”，如：in the 1980s,in ones fifties。 (二)序数词的意义 表示事物顺序，前面一般要加定冠词；表示“又一个，另一个”，前面可加不定冠词。如:a second,a fourth等,与another或 one more/once more(again)同义。 He failed the experiment for the first time,but he didnt give up and tried a second time. The chairs aren’t enough; we still need another five chairs. (三)分数的形 分子用基数词，分母用序数词，当基数词大于“1”，序数词后要用复数形。注意：当分数修饰不可数名词时，谓语动词用单数；当分数修饰可数名词时，谓语动词用复数形。 Two-thirds of the surface of the earth is covered by water. One second(one half) of the students in our class are girls. (四)概数 1.概数的表达： a dozen/dozens of/scores of/a number of/a quantity of/a few/a little/a great deal of/a large amount of/large numbers of/a great(good) many/a supply of/supplies of/a mass of/masses of 2.概数的注意事项： A number of/a few of/few/a great(good)many一般只修饰可数名词复数；a little/a great of/a large amount of只修饰不可数名词；a dozen eggs/half a dozen eggs/three dozen eggs/dozens of her eggs;four score of books/three score year sold/five score of the computers；a quantity of/quantities of/a lot of/lots of/plenty of/a supply of/a mass of/masses of 既可修饰可数名词复数，又可修饰不可数名词；谓语动词的数与quantity,supply,mass variety等保持一致。 (五)倍数的表示 1.倍数(twice...times)+as+形容词/副词的原级+as+比较对象 2.倍数+形容词/副词的比较级+than+比较对象 3.倍数+the+(size/length/height/width/weight/time)+of+比较对象 考题名师诠释 【例1】(2006北京,23)She went to the bookstore and bought .
A.dozen books B.dozens books C.dozen of books D.dozens of books 解析:dozen,score和hundred,thousand等类似，当采用复数形修饰名词时，后面要跟of,如：scores of eggs;thousands of people。但是如果前面跟具体的数字，就要用单数形，并且后面直接跟所要修饰的名词，如：two dozen apples;three hundred trees；注意score除外，如：two score of people。 答案:D 【例2】(2006浙江,15)We always keep spare paper,in case we run out. A.too much B.a number of C.plenty of D.a good many of 解析:本题考查数量表达法的用法，plenty of既能修饰可数名词也能修饰不可数名词；a number of和a good many of只能修饰可数名词复数；too much只能修饰不可数名词，但是表示强调语气，不符合句意。本句含义为：我们经常存有备用纸，以备我们用完时用。 答案:C 链接•思考 对概数既要掌握其所修饰名词的可数与不可数，还要注意概数本身的词义区分。如：too much/plenty of。 【例3】Our city has developed into a big one,which is it used to be. A.four times larger than that B.four times the size of what C.four times the size larger than what D. as four times the size as that 解析:本题考查倍数表达法，根据题干可以推知，其句型为：倍数+the size of+比较对象。该句还可以转换成下列说法：(1)...which is four times larger than what it used to be.(2)...which is four times as large as what it used to be. 答案:B 【例4】(2005湖北，28)What a table!I’ve never seen such a thing before.It is it is long. A.half not as wide as B.wide not as half as C.not half as wide as D. as wide as not half 解析:倍数的表达方通常为“倍数+as+形容词/副词的原级+as+比较对象”结构。本题干的语意为：这个桌子真特别!我从未见过这样的桌子，宽度没有长度的一半儿。 答案:C
