Question

【题目】 Many people may enjoy travelling by air, but few like airline food. Airlines have always tried to improve the food quality and the taste in order to attract more travelers. 【1】 According to some recent scientific researches, a part of the reason is that at high altitude(海拔), we can’t actually taste things well as we do on the ground.

Scientists have found that even before a plane takes off, 【2】 As the plane climbs, the air pressure changes and our noses become more and more senseless. When the plane goes 35,000 feet high, 【3】 They help explain why the tomato juice on airplanes tastes far less sour in the air than it does down on the ground.【4】 Otherwise, the food would be tasteless. Astronauts also have to do with this problem on their journeys for similar reasons.【5】The studies are going on! We are looking forward to any improvements.

A. the nose no longer knows just like being bitten(咬) by a snake.

B. How to solve this problem?

C. the air inside the plane dries out the nose.

D. Getting something tasty in the air is like a dream to the travelers.

Answer 1

【答案】

【1】D

【2】C

【3】A

【4】E

【5】B

【解析】

本文介绍了为什么飞机上的食物为什么不好吃的原因。部分原因是在高海拔地区，事实上我们不能像在地面上那样好好地品尝食物。主要原因是随着飞机的爬升，气压也会发生变化，我们的鼻子也变得越来越麻木。当飞机飞到3.5万英尺高的时候，鼻子不再有知觉。

【1】句意：在空中吃点可口的东西对旅行者来说就像做梦一样。根据下文According to some recent scientific researches, a part of the reason is that at high altitude(海拔), we can’t actually taste things well as we do on the ground.（根据最近的一些科学研究，部分原因是在高海拔地区，事实上我们不能像在地面上那样好好地品尝食物。）结合句意（选项）可知是“在空中吃点可口的东西对旅行者来说就像做梦一样。”故选D。

【2】句意：飞机内部的空气使鼻子干燥。根据下文As the plane climbs, the air pressure changes and our noses become more and more senseless.（当飞机爬升时，气压变化，我们的鼻子变得越来越麻木。）可知上文是关于鼻子的，可知是“科学家发现，即使在飞机起飞之前，飞机内部的空气使鼻子干燥。” 结合句意（选项）可知选C。

【3】句意：鼻子不再有知觉了，就像被蛇咬伤一样。根据上文As the plane climbs, the air pressure changes and our noses become more and more senseless.（当飞机爬升时，气压变化，我们的鼻子变得越来越麻木。）可知“当飞机飞到35000英尺高的时候，鼻子不再有知觉了，就像被蛇咬伤一样。” 结合句意（选项）可知选A。

【4】句意：这也有助于解释为什么航空公司更喜欢吃咸和辣的食物。根据上文They help explain why the tomato juice on airplanes tastes far less sour in the air than it does down on the ground.（它们有助于解释为什么飞机上的番茄汁在空气中的酸味远低于在地面上的酸味。）可知“这也有助于解释为什么航空公司更喜欢吃咸和辣的食物。” 结合句意（选项）可知选E。

【5】句意：如何解决这个问题？根据上文Otherwise, the food would be tasteless. Astronauts also have to do with this problem on their journeys for similar reasons.（否则，食物就没味道了。宇航员在旅途中也会遇到类似的问题。）和下文The studies are going on! We are looking forward to any improvements.（研究还在进行中！我们期待任何改进。）可知是“如何解决这个问题？” 结合句意（选项）可知选B。

五选五阅读主语考查的是学生的文本语篇分析能力，从而使上下文在语义，语法，结构上完整。技巧及注意事项如下：

判断挖空所处的位置：一般来讲位于句首通常是概括文章的总结性话语；文章中部通常是转折或者并列关系；文章末尾通常是总结段落或全文。

根据连接词判断语境：连接词诸如but意味着上下文的语义关系出现转折，遇到此类情况就要弄得上下文说的是什么。而and等并列词语一般是描述前后两个或多个相似的事情。

根据作者语气口吻推断：该类文章一般情况下主旨明确，有作者自己的态度倾向，所以做题时要看出作者持哪一方态度，不能选择有悖于作者思想的句子。
