数词属限定词,它与很多词存在一致关系,分析这些一致关系,可以巧妙地学习数词。
一、 分析数词与名词一致性,巧妙学习数词
基数词(大于1)后面应接复数名词,但复合形容词中的基数词应修饰单数名词,序数词后面应接单数名词。表示第几时可用the+序数词+单数名词,也可用单数名词加基数词。
例1:She has one pink pen
A. one B. once C. one's D. ones
析:D为正确答案。two后面应接复数名词。
例2:We are going to learn ________ next week.
A. Lesson Twelve B. Lesson
C. Twelf
析:A为正确答案。第十二课可表达为Lesson Twelve或the twelfth lesson。
例3:It's ________ walk from here to my school.
A. two-hours B. two hours
C. two-hour D. a two-hour
析:D为正确答案。该空为复合形容词作定语,中间的名词应用单数。
二、 分析数词与量词一致性,巧妙学习数词
数词后面接量词时,数词无论有多大,量词都要用单数形式。
例1:Two ________ died of cold last winter.
A. hundreds old people
B. hundred old people
C. hundreds of old people
D. hundred old peoples
析:B为正确答
例2: Shortly after the accident, two________ police were sent to the spot to keep order.
A. dozen of B. dozens C. dozen D. dozens of
析:C为正确答案。two后面应接单数量词。
三、 分析数词与介词一致性,巧妙学习数词
数词前面加介词常表示年龄或年代,此时数词需用复数形式。这样的场合常见的有:in the 1990's / 1990s (在二十世纪九十年代), by twos and threes (三三两两地), in the eighties (在八十年代), in one's sixties (在某人六十多岁时)。
例1:The hero of the story is an artist in his________.
A. thirtieth B. thirty
C. thirty's D. thirties
析:D为正确答案。in his thirties意为"在他三十多岁时"。
例2:It is rare in ________ that people in ________fifties are going to university for further education.
A. 90s; the B. the 90s; /
C. 90s; their D. the 90s; their
析:D为正确答案。in
四、 分析数词与动词一致性,巧妙学习数词
分数、百分数作主语时谓语动词取决于of后面的名词;one of+复数名词表示总数超过一个,作主语时动词用复数,the only one of+复数名词表示总数中只有一个,作主语时动词用单数;表示重量、长度、价值、时间等概念的复数名词可看成一个整体,作
例1:Ten years ________ a very short time in history.
A. is B. are C. has been D. were
例2:As we all know, three feet________ equal to one meter.
A. are B. is C. were D. was
析:B为正确答案。three feet可看
例3:He is the only one of the employees who________ sent abroad for further training for five years
A. is B. are C. have been
析:D为正确答案。析语境可知,该句表示他是五年来被派往国外培训的唯一一位雇员,所以谓语动词应用现在完成时单数形式 has been。
例4:________ of the land in that district ________covered with trees and grass.
A. Two fifth; is B. Two fifth; are
C. Two fifths; is D. Two fifths; are
析:C为正确答案。分数的表示方法为:先讲分子,再讲分母,分子用基数词,分母用序数词,当分子大于1时,分母用序数词复数形式。因为land为不可数名词,动词应用单数形式。
五、分析数词与冠词一致关系,巧妙学习数词
复合形容词中基数词常与不定冠词搭配,此时基数词若为元音发音开头时,应在其前面加an,若为辅音发音开头的应在其前面加a。
例1:Don't take ________ one-sided view of anything.
A. a B. an C. t
析:A为正确答案。one为辅音发音开头,前面应加
序数词前面通常加the修饰,表示第几次用the+序数词+time,但表示又一次、再一次时,应用a+序数词+time。
例2: I've already asked him three times, I wonder if I can ask him________time.
A. four B. fourth
C. a four D. a fourth
析:D为正确答案。该空语境表示又一次、再一次,应填a fourth。
六、分析数词与倍数搭配关系,巧妙学习数词
数词与倍数(times)搭配常用于A is...times as large/long as B句型 (A是B大小/长度的......倍)或A is...times larger/longer than B (A比B大/长......倍)。
例1:The house rent is expensive. I've got about half the space I have at home and I'm payin
A. as three times much
B. as much three times
C. much as three times
D. three times as much
析:D为正确答案。该空表示我所花的费用是家里的三倍,应使用A is...times as large/long as B句型,here前面省去了as I pay at home。
例2:Americans eat ________ vegetables per person today as they did in 1910. A. m
B. as twice as many
C. twice as many as
D. more than twice as many
析:D为正确答案。as they did in 1990提示该空格处表示倍数,可使用A is...times as large / long as B句型。
例3:After the new machinery was set up, the company produced ________ refrigerators in 2000 as the year before.
A. as twice many B. as many twice
C. twice as many D. twice many as
析:C为正确答案。as the year before暗示该空表示倍数,应使用A is...times as large/long as B句型。
