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
