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.

A. buses make his brain into thinking he has been poisoned
B. buses make him feel very excited
C. he doesn’t like taking a bus to anywhere at all

2.The meaning of the underlined word “motionless” is close to “ ________”.

3.Which of the following can NOT weaken the feeling of sickness in a bus?
A. Looking out of the window
B. Looking at the passage of the bus.
C. Looking at the movement itself.
D. Looking at something quiet.
4.What’s the best title of the passage?

Travel sets us thinking and makes us in discussions of major world problems. Traveling can improve our thinking skills. That’s WHY we travel. What follows is HOW we travel.
CHEAP TRAVEL
The less you spend, the closer you come to the reason you came.
We’re savers by choice when traveling, although we could afford to stay in middle-priced hotels and eat in their restaurants if we cut back on the length of our trips. By spending less we can travel longer and travel better. We meet more locals by using buses rather than taxis and by staying in small family-run hotels and eating in local-style cafes. Spending too much money makes you away from the foreign experience you came to have.
TRAVELERS — NOT TOURISTS
What’s the difference? Travelers are more likely to get deeper into the life of a country than tourists. The way to do this is to do lots of pre-trip reading about the countries we will visit, and try to learn a few words of local languages.
Independent travel is usually far less expensive than packaged tours. We don’t use travel agents because we don’t stay in hotels that charge high, and we can get cheaper tickets on the Internet. We like figuring out where to eat and working out how to get around. This puts us into direct contact with the local people. Independent travel isn’t as comfortable or convenient, but it’s the most meaningful way to travel.
MOVING AROUND
Despite its discomforts, we take public transportation whenever possible. Traveling in a car is easier, but also scarier. In much of the world roads are poor and driving behaviors are not fixed. Luckily, even the less developed countries often have good public transportation systems, riding buses and trains brings us into close contact with the local people.
CARRYING STUFF(东西)
Backpacks work better for long-term travel than the wheeled luggage(轮式行李箱) most middle-aged travelers use. Using luggage is fine with a car, but backpacks are easier for bus and train travel. Best of all, wearing backpacks bridge the gap between age groups — allowing gray-haired travelers like us to make friends with younger travelers.
