问题 In contrast to the substantial muscular activity required for inhalation, exhalation is usually a ______ process.
选项 A、slow
B、passive
C、precise
D、complex
E、conscious
答案 B
解析 - 方程等号：in contrast to表示对比，前后句意构成反义重复。
- 强词和对应：前文提到吸气是需要大量的肌肉活动的，空格和activity根据in contrast to取反，体现呼气是“不需要活动”，负向。slow缓慢的，passive被动的，precise精确的，complex复杂的，conscious有意识的。答案选B。
