考向 05数词
【命题解读】
高考对数词的考查常常出现在听力、完形填空、语法填空和短文改错题型中。数词部分主要考查：
①基数词的用法
②序数词的用法
③倍数的表示方法
【命题预测】
听力理解对数词的考查主要集中在对各种号码、序列等表述。语法填空对名词数词的考查仍然会成为高考的重点，主要集中在给出词根进行词类转化，根据习惯用法或固定短语确定名词的复数形式等。
【名师指导】
1. 注意数词的基本拼写方法
从近年高考试题看，高考语法填空对数词的考查离不开具体的语境，在语境中考查数词的相关知识。做题时，既要全面、整体地看题干，还要注意分析句子成分，并根据提示词来确定名词的相关考点。通常，涉及名词考点的试题包括：
（1）根据语境判断名词的单复数；
（2）提示词是形容词、动词等此类，根据句子成分和词缀知识加上相应的后缀变成名词；
（3）名词的固定搭配；
（4）名词的所有格及名词的其他相关知识
2. 关注常见的号码及序列等的表述
语法填空对名词的考查涉及名词各方面的知识，解题时要注意首先根据提示信息确定考点，试题是考查名词的词类转换，还是考查复数名词、名词的所有格，还是考查主谓一致、名词的固定搭配等，确定了考点之后，再结合其他相关知识来做出正确解答。
3. 熟悉各种比较级倍数的表达方式
高考对名词的考查注重基础，我们在平时的复习中要打好基础，掌握足够的考纲词汇，并熟知其常见搭配和用法，并注意熟练掌握常用的名词词缀知识。

【解析】考查与数量有关的名词、代词和限定词。句意：超过8万人热衷于著名的电视秀节目《奔跑吧，兄弟》。这里thousand表示数量，此处根据句意应该是8万人是肯定的数量表达，故用数字80单数形式加thousand 结构表达。而如果使用A选项thousands of的话，就是概数，表达的是数以万计。而C选项后面不应该加上of, D选项更不应该加上thousands复数形式。故选B。
42. C
【解析】考查短语辨析及分数的表示法。句意：许多人偏爱华为手机，其中大约五分之四是成年人。a number of +可数名词的复数形式，表示“一些、许多”，其谓语动词要用复数形式”；the number of +可数名词的复数，表示“......的数量”，其谓语动词要用单数形式。根据语境可知，第一空是指“许多人偏爱华为手机”。由此可知，第一个空格处是指“许多”，可知要用a number of。第二空格为分数，分数的表达方式为：分子用基数词，分母要用序数词，当分子大于1时，分母用复数形式。“五分之四”的表示法为four-fifths。综合可知，本小题的答案为C。故选C。
43. C
【解析】考查倍数表达法。句意：当收集有关总统丑闻的记录数据时，磁带的长度是大西洋深度的35倍。表示倍数的句型：A is/was 倍数+the+表示长（宽，高等）的名词+of+B。使用as…as句型，倍数要置于as…as之前，故A、B项错误。D 选项结构不构成比较。C选项中“of短语”构成“比较”的含义。故选C。
44. C
【解析】考查固定表达。句意：一项最近的研究表明大多数孩子喜欢玩游戏，只有很小一部分人每天阅读。后面提到了most of them…表示“大多数人……”，那前面就是说剩下的少数人。a minority of…表示“少数人……”。故选C项。
45. D
【解析】考查数词的用法。句意：我们班五分之二的学生下周要去北京参加夏令营。分数的构成：分子用基数词，分母用序数词；当分子大于一时，分母用复数形式。“分数+of+名词”作主语时，如果名词是复数，谓语动词用复数形式，故选D。
