【题目】Traveling makes us feel sick because modern transport tricks the brain into thinking we have been poisoned, a scientist has said.
Being in a car, train, boat or plane makes conflicting signals in the brain which causes an action similar to something that happens when someone is poisoned. Dr Dean Burnett, from Cardiff University, said the feeling of sickness is caused because the brain thinks the body needs to remove a toxin through vomiting . But in fact, the “poisoning”effect is caused by the mixed messages-- for the muscles , they tell the brain the body is motionless, but for the ears, they got the feeling that the body has some movement.
Dr Dean Burnett explained that reading in a car made the feeling of travel sickness worse, because the eyes were focused on a small, motionless space and gave the brain no information to explain that the body was moving.
The feeling of sickness could be weakened by looking out of a car window because this showed the brain that movement was taking place. “You can see the passage and movement itself, and that balances the system,” he said. “The brain’s going: ‘Oh, look, things are moving--I must be moving’--and then it calms down the sickness.”
Dr Burnett said there was no clear reason why some people suffered from car sickness more than others. But he said there were several other aspects of modern life with which the brain had not yet recognized or understood.

【1】细节理解题。根据文中的句子Traveling makes us feel sick because modern transport tricks the brain into thinking we have been poisoned,可知，他之所以晕车是因为公共汽车欺骗他的大脑，使他的大脑认为他中毒了，故答案选A。
【2】词义猜测题。根据下文but for the ears, they got the feeling that the body has some movement.但是对于耳朵，他们感觉身体有一些运动，可知此处句意为“对于肌肉，它们告诉大脑身体是静止的”，所以motionless意思是“静止的”，结合选项可知与C选项意思相近，故答案选C。
