1、分析一致性，巧妙学数词数词属限定词，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 and two grey _. A. one B. once C. ones 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
2、B. Lesson Twelfth C. Twelfth Lesson D. the Lesson Twelfth 析：A为正确答案。第十二课可表达为Lesson Twelve或the twelfth lesson。 例3：Its _ 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 col
3、d last winter. A. hundreds old people B. hundred old people C. hundreds of old people D. hundred old peoples 析：B为正确答案。使用数词+量词+复数名词结构时，量词应用单数形式。 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
4、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 1990s / 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 ones 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. thirtys 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
5、 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 the 90s表示在90年代；in their fifties表示在他们五十多岁时。 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
6、，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，作主语时动词用单数。 例1：Ten years _ a very short time in history. A. is B. are C. has been D. were 析：A为正确答案。Ten years 可看成一个整体，作主语动词用单数。 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可看成一个整体，作主语动词应用单数。 例3：He is the only
7、 one of the employees who_ sent abroad for further training for five years. A. is B. are C. have been D. has 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
8、. 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：Dont take _ one-sided view of anything. A. a B. an C. the D. / 析：A为正确答案。one为辅音发音开头，前面应加a。 序数词前面通常加the修饰，表示第几次用the+
9、序数词+time，但表示又一次、再一次时，应用a+序数词+time。 例2： Ive 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
10、B大/长.倍)。 例1：The house rent is expensive. Ive got about half the space I have at home and Im paying _here. 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 e
11、at _ vegetables per person today as they did in 1910. A. more than twice 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。
