题目内容
16.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(气压)reduces one third of the sensibility(感觉)of our taste buds(味蕾).So our taste buds become senseless.The sad face,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 feelings 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,making food taste good is still hard for them.

分析 本篇文章讲述了一个问题--为什么在飞机上食物变得很难吃?科学家的回答是--由于海拔升高的原因,气压的改变钝化了我们三分之一的味觉,我们的鼻子变得干燥,对气味不敏感.这也是为什么飞机餐通常比较"重口"(偏咸且偏辣)的原因.科学家和志愿者尝试用一些方法改善飞机上的用餐,但由于气压的变化的原因,想要让飞机餐变得好吃还是很难.
解答 61.B 词义理解题.找到原句To solve this problem,airlines try hard to improve their food.这一句说到"improve their food",可以推测this problem是和food有联系的,可以排除A选项;根据原句前面一句But it is common that they feel bad about food taste.Do you agree?可知是"食物很难吃",因此答案为B.
62.C 推理判断题.根据To solve this problem,airlines try hard to improve their food.可知,为了解决食物难吃这个问题,航空公司努力改善他们的食物,故选C.
63.B 细节理解题.根据第三段句子 the change in air pressure(气压)reduces one third of the sensibility(感觉)of our taste buds(味蕾)可知,气压的变化减弱了我们三分之一的味觉.故选B
64.D 推理判断题.仔细理解最后一段内容可知,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,making food taste good is still hard for them.科学家认为要解决这个问题不容易的原因是他们无法成功地处理这种特殊的环境,比如气压的改变.因此答案为D.
65.A 内容归纳题.本文主要讲了"飞机餐为什么难吃",因此答案为A.
