Did you go on a long train or bus journey(旅行)? Did you feel tired during the journey? Have you ever wondered why you feel tired on a long journey, even when you've been sitting the whole time?
Research has found that feeling tired is actually a symptom(症状) of motion sickness(晕动病). Almost everyone will become motion sick. And about one person in three is very sensitive(敏锐的) to motion sickness.
Research has found that while passengers are traveling, their brains(大脑) are working hard to process(加工) the motion of the vehicle(车辆). And they may feel a mismatch(不协调) between what their feelings are telling them and what their bodies expect to feel. Changes in speed, turning corners, and stopping and starting are motions that our bodies are not really used to, and these can make us feel unwell.
Some people may get sickness faster than others. ▲ But it has been found that the longer you travel, the more likely you are to feel sick. Even the activities we do while traveling can have an effect(影响) on how we feel. Passing the time by reading a book or watching a film can create further sensory confusion(感觉困惑), as our attention is no longer focused on processing the vehicle's motion.
To cut down the effect of motion sickness, you should sit as far forward in a vehicle as possible, there you can feel less motion. You can also get a window seat. And it can also help to close your eyes and sleep.

【分析】
首先分析各题解题思路：27题需观察文章开头引入方式，原文以连续问句引出话题；28题要概括第三段核心内容，明确其是解释晕动病的成因；29题需结合第四段前后逻辑，选择衔接合理的句子；30题要定位原文减少晕动病的方法，匹配对应选项。
【解析】
27题：文章开头用三个关于长途旅行的问句引出话题，这种引入方式是提问，对应选项B，故选B。
28题：第三段主要解释晕动病的发生机制：乘客旅行时大脑处理车辆运动，身体感受与预期不协调导致不适，即晕动病的成因，对应选项A，故选A。
29题：第四段前半句提到“有些人更快感到不适”，后半句说明旅行时长的影响，中间需衔接逻辑，C选项“我们仍不清楚原因”符合，后文已知旅行时长的影响，中间对应个体差异的未知原因，故选C。
30题：根据最后一段“坐车辆前部、闭眼睡觉可减少不适”，对应方法是①睡觉、③坐前部，故选C。
