Question

【題目】根據(jù)短文內(nèi)容，選擇最佳答案。 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 plan. 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 one third of the sensibility（感覺）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.

A.passengers stay long in the plane

D.food on the plane is expensive
（2）What do airlines do to solve this problem?
A.Get more customers.
B.Offer more food.
C.Improve their food.
D.Reduce the ticket price.
（3）As the plane moves up, the change in air pressure reduces of the sensibility of our taste buds.
A.half
B.one third
C.one fourth
D.one fifth
（4）Why do scientists feel it hard to made food on the plane taste good?
A.The volunteers don't know about food taste.
B.The volunteers don't understand them.
C.They can't find enough volunteers.
D.They can't deal with the special environment successfully.
（5）What is the best title of the passage?

D.The Change in Air Pressure

Answer 1

【答案】
（1）B
（2）C
（3）B
（4）D
（5）A
【解析】文章大意：本文講述的是為什么飛機(jī)上的食物口感不好的原因，及其改進(jìn)的措施。據(jù)科學(xué)家研究，在高海拔情況下，人的感覺變了，三分之一的味蕾減少了，因此，要做出口感好的食物還很困難。
（1）推理判斷題。題意：在第二段里的 “this problem” 意思是什么？A. passengers stay long in the plane乘客在飛機(jī)上待的時(shí)間長(zhǎng)；B. food on the plane tastes bad飛機(jī)上的食物口感不好；C. passengers have no food to eat乘客沒有食物吃；D. food on the plane is expensive飛機(jī)上的食物貴。這個(gè)問題是第一自然段里提到的主要內(nèi)容：But it is common that they feel bad about food taste. 乘客普遍認(rèn)為食物的口感不好。故選：B。
（2）細(xì)節(jié)理解題。題意：航空公司做什么來解決這個(gè)問題？A. Get more customers.得到更多的顧客；B. Offer more food.提供更多的食物；C. Improve their food.改善他們的食物；D. Reduce the ticket price.降低票價(jià)。由第二段第一句：To solve this problem, airlines try hard to improve their food.可知，航空公司通常改善食物的方式來解決這個(gè)問題。故選C。
（3）細(xì)節(jié)理解題。題意：隨著飛機(jī)上升，氣壓的改變使得我們的味蕾減少了多少？A. half 一半；B. one third三分之一；C. one fourth四分之一；D. one fifth五分之一。由第三段里的：As the plane moves up, the change in air pressure（氣壓）reduces one third of the sensibility（感覺）of our taste buds（味蕾）可知，減少了三分之一。故選B。
（4）細(xì)節(jié)理解題。題意：為什么科學(xué)家們感到使飛機(jī)上的食物可口難？A. The volunteers don't know about food taste.志愿者不了解食物的口感；B. The volunteers don't understand them.志愿者不理解他們；C. They can't find enough volunteers.他們找不到足夠的志愿者；D. They can't deal with the special environment successfully.他們不能成功處理特殊的環(huán)境。由短文最后一句：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.可知因?yàn)椴荒艹晒μ幚硖厥獾沫h(huán)境，所以他們認(rèn)為要改善飛機(jī)上的食物的口感難。故選D。
（5）主旨大意題。題意：短文最好的標(biāo)題是什么？A. Taste of Airplane Food飛機(jī)上食物的口感；B. Airplane Travel飛機(jī)旅行；C. Scientific Research on Noses關(guān)于鼻子的科學(xué)研究；D. The Change in Air Pressure氣壓的改變。短文主要講述的是為什么飛機(jī)上的食物口感不好的原因，及其改進(jìn)的措施。故選A。
