31. A. although B. while C. therefore D. then
答案A。仔细阅读上下文，就能看出“and 31 the passengers had fastened their seat belts, they were suddenly thrown forward.”两个句子是对比关系，意思为“尽管旅客系着安全带，但大家还是被抛向前面”。
32. A. showed B. presented C. exposed D. appeared
答案D。A选项正确说法应该为“showed up”，B和C选项意思和用法不符合语境;只有D选项正确。Appear意为“出现”。
33. A. well B. still C. calm D. quiet
答案C。应该注意but一词的意义在于引起一个相反的概念。“She looked very pale, but was quite 33 .”也就是说，所选择的单词应该是pale一词含义的反义词。所以用C选项最合适。全局意思为“尽管她脸色苍白，但她很镇静”。其他选项意思或用法有误。
34. A. inquired B. insured C. informed D. instructed
答案C。A选项意思为“询问”;B选项意思为“保险”;C选项意思为“告诉”;D选项意为“指示”。只有C选项的意思和用法正确。
35. A. hesitation B. surprise C. doubt D. delay
答案A。A选项意为“犹豫”，最符合本句话的场景。全句意思为“犹豫一会后，一个人站了起来跟服务员进了驾驶舱”。
36. A. to B. by C. near D. on
答案A。close to属于固定搭配词组，意思为“接近”。其他选项的搭配不正确。
37. A. surround B. circle C. observe D. view
答案B。A选项意为“包围”;B项意为“绕圈子”;C和D选项的意思为“观察，看”。在这里可以判断，飞机是在机场上空绕了几个圈子。
38. A. intimate B. familiar C. understood D. close
答案B。A选项意思为“亲密的”;B项意为“熟悉”。本句话的含义是，飞机是在机场上空绕了几个圈子，目的是熟悉空管指示。
39. A. moment B. movement C. idea D. affair
答案A。A选项的意思为“时刻”。全句意思是“可怕的一刻来临了，他要降落了”。其他选项的意思不正确。
40. A. as B. unless C. while D. so
答案A。注意本处的意思为“当……时候”。A项as与C项while的意思都是“当……时候”，但while指一个较长的时间过程，而as指事情发生的一刻。由于飞机触地touch the ground是一个短暂性动作，此处应选择as。

Lucia: Thanks. I have a terrible headache. It seems to be flu.
A. What do you want to do? B. Can I help you?
