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

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 ord="or">or ord="more">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ord="a">a ord="half">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.
