数词在各个题项中，单选、阅读、听力、写作中发挥着很强的作用，往往用以说明事实的精确性和可信性。数词是由两大部分构成的即基数词和序数词，而其他数字表示法如分数，小数等均由这两大部分的不同组合而构成。

1.B

2. C 表示"几十"的数字的复数与所有格代词一起来用以表示人的年龄，本句为"二十多岁"。

3.C 定冠词"the"和数的复数形式在一起表示年代。

4.D 序数词前面加不定冠词表示"又一次"(已经四次了)

5.A 这里"first"有人说起副词作用，可以看成表语，也可以看做一种"取得第一名"的习惯用法。

6.D 序数词和名词共同构成的专有名词还可以是thc Second World War的形式。

7.C 只有C项为正确的表达方式，或者也可以写成"one or two days".再如：one hour and a half或one and a half hours.

8.B "in half"表示"分成一样大小的两半"。也可以说"cut…in two"

9.B 再如twice the height(depth，width，weight，etc.)of

10.D either…or…连接主语用就近原则。be to hand out the prizes意为"要颁发奖品"。

11.答案为B。百分比作修饰语，前面不加冠词且不能加复数。

12.答案为B。分数做定语，分子用基数词，分母为序数词，当分子大于1时，分母用复数，本题中，其它表达方式均不正确。

13.答案为A。表增加或减少的数量的百分比，用by+百分数表示。

14.答案为A。不可数的名词的百分比用单数;可数名词的百分比则用复数。C项时态不对，另如：90 percent of the population here are peasents.这个句子中population的意思是people.

15.答案为A。"dozen"与数词或many，several等词连用时复数一般不加s，故B、C两项不选。此外，dozen与数词连用做定语，一般也不加of.当然也有例外：Place them in dozens on the table.dozens表数量很多。Two dozen of these are wanted.dozen后面有of因为有限定词these，the等。Dozens of people were here.dozens of也表示"很多"。

16.答案为B。"半打"的表达方式一定要用"hall a dozen"。

17.答案为B。score做定语修饰名词用a(three)score of，而不用复数形式;常用"scores of"为其复数形式，意为"大量"，但有：three score and ten，a score or more

18.答案为B。"hall"起副词作用，修饰过去分词"done"，因为这个过去分词表状态，故"half"应在"done"前。再如：well done，well known，不用a half修饰done，故不选C、B两项。

19.B意为"同时"，不是"立刻"。

20.B

2l.A 如：tens of thousands of(小数在前，大数在后)thousands and thonsands of(两数一样大)。

22.B 居住的门牌号用介词at+号数+街道名"。

23.A

24.答案为D。"walk"作为名词，常与不定冠词连用。注意：在表数量的合成词中，名词部分为单数，如：a two-year-old boy.

25.答案为B。"在20世纪40年代"，必须有定冠词"the".此外，年代后要加's或s。"他已经40多岁了"要用in his forties。

26.答案为B。dozen与数词或多或少several, many连用时，复数不加s。dozens of表示数量很多，在修饰有these，the等词限定的名词时，可用dozen of的形式。如：three dozen of these eggs.

27.C 28.A 29.C 30.B 31.D 32.C
