If you get seasick easily, you may prepare for boat rides with some medicine and other helpful stuff. Now there's one more remedy: Timing your breathing to control the nauseating (作呕的)motion. The technique presumably works because it helps control gravity sensors (传感器)in the abdomen (腹部)—a lesser-known input to our fine-tuned balance system. The brain is traditionally thought to sense body position in three ways. The inner ears sense motions of the head; the eyes see where the head is; and tiny sensory organs in muscles and tendons (筋)sense where the rest of the body is. More recently, researchers have realized that sensors in many other parts of the body also play a role: in the abdomen, the lower organs, and even blood vessels. As long as all of these sensors send matching signals to the brain, we feel directed. But if one or two don't match up, the brain gets confused and we become nauseated. According to the passage, which of the following helps control gravity sensors in the abdomen? A. Timing one's breathing.B. The nauseating motion.C. Some medicine.D. Our fine-tuned balance system.

题目解答
答案
解析
考查要点：本题主要考查学生对文章细节的理解能力，需要根据上下文准确提取关键信息。
解题思路：文章第一段明确提到“Timing your breathing to control the nauseating motion”（通过控制呼吸来缓解晕船引起的不适），并指出这种技术的作用原理是“control gravity sensors in the abdomen”（控制腹部的重力传感器）。因此，直接对应选项A。其他选项或为干扰项（如B、C）或与题干无关（如D）。
关键信息定位：
- 第一段首句：文章开篇提出“Timing your breathing”是缓解晕船的新方法。
- 第一段末句：进一步解释该方法的作用机制是“control gravity sensors in the abdomen”（控制腹部的重力传感器）。
- 选项分析：
- A. Timing one's breathing：与文章直接对应，正确。
- B. The nauseating motion：是晕船的症状本身，而非解决方法。
- C. Some medicine：文章开头提到药物是传统方法，但未说明其作用机制。
- D. Our fine-tuned balance system：平衡系统是整体概念，而非具体方法。
