数词考点大盘点
数词在高考中虽然不像其它词类那么"热",但也有其考查的重点和难点,须引起同学们的注意。
一、考查基数词的用法
1. 基数词hundred, thousand, million等表示确切数目时,其词尾不能加-s,其前面可用数词或several, some等修饰;当表示笼统数目时,其词尾要加-s,可跟of连用,其前不能用数词,但可以用several, some等修饰。
【原题再现】1. ________ people in the world are sending information by e-mail every day.
A. Several million B. Many millions C. Several millions D. Many million
2. dozen和score的用法要注意以下几点:
1) dozen与数词或many, several等连用时,不加-s,所修饰的名词前常省去of。如two (many, se
veral) dozen pencils。但是,在a dozen of these / those people, two dozen of them等短语中应加of,这是习惯用法。
2) two score of people中应加of,但在three score and ten people(70人)中,不加of。
3) 表示"几十;许多"时,可使用dozens of; scores of形式。

A. asked; dozen B. suggested; dozens of C. had; dozen D. persuaded; dozens
3. 注意年龄、年代的表达法。表达"在某人几十岁时"用"in one's +逢十的基数词复数";表达"在几十年代"时,用"in the +逢十的基数词复数"。

二、考查序数词的用法
序数词一般由基数词+th构成。以y结尾的基数词构成序数词时,先把y变为i,再加eth。如twentieth; fiftieth。常用的不规则的序数词有:first, second, third, fifth, eighth, ninth, twelfth。序数词前通常要加定冠词the,但序数词不表示顺序而表示"再一;又一"时,前面要用不定冠词a(an)。

三、考查分数和百分数的用法
表示几分之几或百分之几的人或物时,须在分数或百分数和人或物之间加of。若充当主语,谓语动词的数须与of后的名词保持一致。

A. Two fifth; is B. Two fifth; are C. Two fifths; is D. Two fifths; are

英语中表达倍数常用下列句型:
1. A is three / imes the size / height / length / f B.
2. A is three / imes as big / high / long / as B.
3. A is three / imes bigger / higher / longer / han B.
用times表示倍数时,一般只限于三倍或三倍以上的数,表示两倍常用twice或double。

例题解析
1.---What time is it now? ---It is___________.
A. eleven and thirty B．eleven thirty C. thirty eleven D．eleven—thirty
解析:考查英语中时间的表达方法。在英语中，时间用基数词表示，先读“时”，再读“分”，11：30读作eleven thirty，还可以表示为 half past eleven。 答案B
2.She has been skating for_____________．
A. three and a half years B．three and half a year
C．three and a half year D．three years and half
解析:考查“三年半”，表达方法。“三年半”有两种表达方法：three and a half years或 three years and a half，故选项A正确。答案A
3．I have to write a ______ composition every other week．
A. six-hundred-words B．six-hundreds—words C. six-hundreds—word D．six-hundred—word
考查整“百”的表示方法及名词做修饰语时用单数的规则。数词hundred做定语时不加“s”，即“几百”用“基数词+hundred'’表示。另外，此题中的“六百字”应看做一个整体来修饰名词co
mposition，所以要加连字符“--”，且word用单数形式。由此可见，选项D正确。
答案D
4．The hall can hold ______________people．
A. five hundred and fifty five B．five hundred fifty-five
C．five hundred and fifty-five D．five hundreds and fifty five
考查数字的读法。“几十几”的数字，构成是先说“几十”再说“几”，中间用连字符“一”。百位和十位之间用and连接，百位不能加“s”．所以选项C正确。答案C
5.There are eight classes in our grade．I'm in ______ .
A. Grade Three，Class Two B. Class Two，Grade Three
C. grade three，class two D．class two，grade three
解析:考查基数词的用法。“几年级几班”，用“名词+基数词”表示，此时作为专有名词必须大
写。英文的排列顺序是“先小后大”，即“先读班级后读年级”，所以选项B正确。答案B
6.1990s is read in English as______________ ．
A. twenty ninth B．twenty ninths C. nineteen nineties D．nineteen ninety
解析:考查年代的读法。1990s代表“20世纪90年代”，按正常的读法，年代分“前两位”和“后两位”。本题前两位是“19”，即 nineteen；后两位是“90”，因为有s，所以用 nineties．因此选择选项C。 答案C
7．We are going to learn ______ next week．
A.Lesson Four B．Lesson Fourth C．Fourth Lesson Fourth D．the Lesson
解析:考查基数词与序数词的不同表达方法。“第几课”可用“Lesson+基数词”表示，也可用“定冠词the+序数词+Lesson'’表示，因此选项A正确。答案A
8.He left his hometown ．
A．when he thirties B．in the thirties C. in his thirties D．at thirties
