Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plane. So airlines( 航 空 公 司 ) offer passengers food. But it is common that they feel bad about food taste. Do you agree?

To solve this problem, airlines try hard to improve their food. They would like to do so because they don’t want to lose customers.

However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude(海拔) we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure(氣壓) reduces(降低) one third of the sensibility(感覺) of our taste buds ( 味 蕾 ). So our taste buds become senseless. The sad fact, however, is that our noses don’t know it.

All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy(辛辣的) food. Without doing so, the food would be tasteless.

Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feeling about food taste.

Though scientists try their best, it is not as easy as they thought. Because they can’t deal with the special environment successfully, such as the change in air pressure(氣壓), making food taste good is still hard for them.

1.In Paragraph 2, this problem means________.

A. passengers stay long in the plane B. food on the plane tastes bad

C. passengers have no food to eat D. food on the plane is expensive

A. No one can find out the reasons

B. people can taste well anywhere and anytime

C. high altitude is part of the reason of plane food’s bad taste

D. our noses are not dry or wet on the plane all the time

3.Why do scientists feel it hard to make food on the plane taste good?

A. The volunteers don’t know about food taste.

B. The volunteers don’t understand them at all.

C. They can’t find enough volunteers to try it.

D. They can’t solve the special environment problem.

4.What is the best title of the passage?

A. Taste of Airplane Food. B. Airplane Travel.
