本文介紹了為什么飛機上的食物為什么不好吃的原因。部分原因是在高海拔地區(qū)，事實上我們不能像在地面上那樣好好地品嘗食物。主要原因是隨著飛機的爬升，氣壓也會發(fā)生變化，我們的鼻子也變得越來越麻木。當飛機飛到3.5萬英尺高的時候，鼻子不再有知覺。

【1】句意：在空中吃點可口的東西對旅行者來說就像做夢一樣。根據(jù)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.（根據(jù)最近的一些科學研究，部分原因是在高海拔地區(qū)，事實上我們不能像在地面上那樣好好地品嘗食物。）結合句意（選項）可知是“在空中吃點可口的東西對旅行者來說就像做夢一樣�！惫蔬xD。

【2】句意：飛機內部的空氣使鼻子干燥。根據(jù)下文As the plane climbs, the air pressure changes and our noses become more and more senseless.（當飛機爬升時，氣壓變化，我們的鼻子變得越來越麻木。）可知上文是關于鼻子的，可知是“科學家發(fā)現(xiàn)，即使在飛機起飛之前，飛機內部的空氣使鼻子干燥。” 結合句意（選項）可知選C。

【3】句意：鼻子不再有知覺了，就像被蛇咬傷一樣。根據(jù)上文As the plane climbs, the air pressure changes and our noses become more and more senseless.（當飛機爬升時，氣壓變化，我們的鼻子變得越來越麻木。）可知“當飛機飛到35000英尺高的時候，鼻子不再有知覺了，就像被蛇咬傷一樣�！� 結合句意（選項）可知選A。

【4】句意：這也有助于解釋為什么航空公司更喜歡吃咸和辣的食物。根據(jù)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.（它們有助于解釋為什么飛機上的番茄汁在空氣中的酸味遠低于在地面上的酸味。）可知“這也有助于解釋為什么航空公司更喜歡吃咸和辣的食物�！� 結合句意（選項）可知選E。

【5】句意：如何解決這個問題？根據(jù)上文Otherwise, the food would be tasteless. Astronauts also have to do with this problem on their journeys for similar reasons.（否則，食物就沒味道了。宇航員在旅途中也會遇到類似的問題。）和下文The studies are going on! We are looking forward to any improvements.（研究還在進行中！我們期待任何改進。）可知是“如何解決這個問題？” 結合句意（選項）可知選B。

五選五閱讀主語考查的是學生的文本語篇分析能力，從而使上下文在語義，語法，結構上完整。技巧及注意事項如下：

判斷挖空所處的位置：一般來講位于句首通常是概括文章的總結性話語；文章中部通常是轉折或者并列關系；文章末尾通常是總結段落或全文。

根據(jù)連接詞判斷語境：連接詞諸如but意味著上下文的語義關系出現(xiàn)轉折，遇到此類情況就要弄得上下文說的是什么。而and等并列詞語一般是描述前后兩個或多個相似的事情。

根據(jù)作者語氣口吻推斷：該類文章一般情況下主旨明確，有作者自己的態(tài)度傾向，所以做題時要看出作者持哪一方態(tài)度，不能選擇有悖于作者思想的句子。
