但是，下面一题却不能选sign，也不能选mark，而选symbol(象征)：
The lion is considered the king of the forest as it is a(n) _____ of courage and power. A. example C. mark
B. sign D. symbol
顺便说一句，在近几年的高考中像这类结合词义区别以及语境和生活常识进行考查的试题经常出现，同学们需引起注意。
9. “May I take your order now?” “We’d like three black _______ and two green _______.” A. coffee, cups of teas C. cups of coffee, tea
B. coffees, teas D. cup of coffees, teas
【陷阱】误选C，认为coffee和tea均为不可数名词，不能后加复数词尾-s，从而排除选项A、B、D。
【分析】选B。有的同学认为 coffee 和tea是物质名词，不可数，不能用 three coffees, two teas 这样的表达。其实，coffee既可用作不可数名词，表示“咖啡”这种物质，也可用作可数名词，表示“一杯咖啡”，即在口语中 three coffees 就等于 three cups of coffee。同样，“三杯茶”既可说成 three cups of tea，也可说成 three teas；“三杯啤酒”既可说成 three glasses of beer，也可说成 three beers。
10. _____ is a good form of exercise for both young and old. A. Walk C. The walk
【陷阱】容易误选A或D。 【分析】最佳答案为B。分析如下：
(1) 首先，选项D不如选项B佳，因为，不定式通常表示特定的动作，而动名词才表示习惯性的动作。
(2) 尽管walk用作名词时可以表示“散步”，但它是可数名词，指的是一次一次的具体的散步，而不表示抽象意义或泛指意义的“散步”，要表示此义，要用动名词 walking。比较：
How about going for a walk? 出去散散步如何?
Walking does good to your health. 散步对你的健康有益。
类似地，dance 和 dancing 以及 swim 和 swimming 的区别也是一样：
B. Walking D. To walk
(1) 名词的 dance表示“跳舞”，是可数名词，指的是一次一次的具体的跳舞，而不表示抽象意义或泛指意义的“跳舞”，要表示后者的意思，要用动名词转化来的名词 dancing。比较：
Let’s have a dance. 我们跳曲舞吧。
He is interested in dancing. 他对跳舞感兴趣。
(2) 名词的 swim表示“游泳”，是可数名词，指的是一次一次的具体的游泳，而不表示抽象意义或泛指意义的“游泳”，要表示后者的意思，要用动名词转化来的名词 swimming。比较：
She had a swim every day. 她每天游一会儿泳。 She loves swimming. 她喜欢游泳。 ◆精编陷阱题训练◆

【答案与解析】
1. 选A。hair 可用作可数或不可数名词，用作可数名词时，指一根一根的毛发或头发，如说 There’s a hair in my soup (我的汤里有根头发)；用作不可数名词时，则是整体地指一个人的头发。
2. 选B。需根据句意来分析。have no sense of direction 意为“没有方向感”。 3. 选B。需根据句意来分析。attempt 在此表示“尝试”。
4. 选B，由于上文说 didn’t have to work，所以下文相应的语境应是 did it by choice。类似地，下面一题应选D，也是因为choice与下文的have to do it 相呼应：

B. duty D. choice B. news D. idea

11. 选D。room 为无生命名词，不用 room’s 这样的所有格形式，在此可直接用名词
作定语。类似地，下面一题要选B，也是一样的道理（名词作定语通常用单数不用复数）：
