1.语境题.本题的解答有赖于对上下文的理 解.文章开头的第一句
是主题句,意思是作为一个到过很多地方的医生,我在飞机上花费了很
多 时间,听到了那样的可怕的事情飞机上有医生吗?而第二句是讲自
己以前经历过一次这样的事情.作者作 为医生,是被叫到去救人的.所以
考察四个选项,call是做合适的.

2.语 境题.分析上下文可知,该题所填入的词是指上一句中我经历
的那件事,考察四个选项,可知应该选ac cident,其意思为事故,意外的
事情.本题有可能误选condition,这是因为受到中文表 达的影响,只要
分析上下文的语态,就能够排除condition.

3.语境题.本题首先应该明确四个选项词汇各表示什么.how soon
指在多长时间之后,how long指多长的时段,how many值数量的多
少,how often指事情发生的频率.在分析本句话how __3__ this kind
of thing happens.由this kind of thing能够首先排除how many,再
根据中文表达习惯,能够确定应该选择how often,意思为这样的事情多
长时间会发生一次.

4.词汇搭配题.本题所 填入的词汇须满足两个条件,首先能够和介
词with搭配,其次符合上下文的意思.由此能够确定应该 选择
nt with的意思为使面临, 使面对,本句意思为当遇到
这样的半空中的医疗事故.

5.词汇 搭配题.本题考查access与介词构成短语的意思的辨析.由
此能够确定准确答案为access to,意思为接近;通向…的入口.本句话
的意思为在没有医护人员和通常的急救设备的情况下.

6.语境题.对本题所在的句子完整分析后,前半句话在句中作状语,
并且是做时间状 语,所以应该选择when.

注意在引导时间状语从句时when和while的区别. when，while都
有“当……时候”的意思.when既可表示某一点时间,也能够表示某一段时间.在when引导的时间状语从句中,其谓语动词能够是延续性的,
也能够是非延续性的,可 与主句中的谓语动词同时发生,也可在其后发
生.while只能表示某一段时间,不能表示某一点时间 .在while引导的
时间状语从句中,其谓语动词只能是延续性的,而且也只能与主句中的
谓 语动词同时发生或存有.另外,when和while的区别还在于：while
引导的时间状语从句多 用实行时态,而when引导的时间状语从句多用
一般时态.

7.词汇搭配题.分析本句话,the New and Journal of Medicine
last week __7__ a study about in flight medical events.其主语
为the New England Journal of Medicine,宾语为a study,由此能够
确定应该选择含有发布意思的publish.

8.词汇搭配题.本题考查固定搭配with interest,其意思为有兴趣
地,带利息,通过某种关系.

9.语境题.本题的解答有赖于对本句话理解,注意到本句中的
estimate和every day ,并且考察四个选项后,可知应该选择average,
即平均每天有三十个空中医疗事件发生.

10.语境题.本题乍一看并不知道所填入的形容词到底是什么,但当
看到下一句后就 能够确定答案.fainting and dizziness are the
most frequent complaints,其意思为昏厥和头昏是最经常发生的疾病.
由此可知这些医 疗时间都是不太严重的,由此能够确定第十题应该选
serious.

11.语境题.本题主要考察两个句子之间的逻辑关系,需要综合考虑
上下 文.上句中说他们中的绝大部分都不严重,下一句又说他们中的13%
严重到要求飞行员改变航线.由此 能够确定两句话之间是转折的关系,
应该选择but.

12.词汇搭配题.本题所填入的词汇需要满足连个条件,首先能够构
成*(动词) do sth. ,其次还要符合上下埃文的意思.由此首先能
够排除B和C两个选项.require比comm and的语气要弱,require仅
仅要求,而 command含有命令的意思,对于如此紧急的时间,应该选用
command.

13.语境题.分析本句话The most common of the serious
emergencies __13__ heart trouble, strokes,and difficulty
breathing.前面总述the serious emergenci es,后面是分述几种疾病,
由此能够确定应该选择include,其意思为含有,包括.

14.语境题.本题乍一看并不知道所填入的形容词到底是什么,但当
看到下一句后就能够 确定答案.下文中讲如果你在高于海平面5000到
8000英尺的地方机舱内的压力就会粗暴的袭击他 们自己.由此能够判断
出前面所填入的形容词是stressful,意思为有压力的,急迫的.

15.语境题.本题考查定语从句的关系代词,分析可知从句的先行词
为they,由 此可知应该选择who.

知,前后两个分句的意思是相反的.后面将由心脏病的乘客会因为其血
液中的含氧量的 降低而发病,说明这些心脏病人很难忍受这种压力.由
此能够推断出正常人能够很轻松的应对这种压力, 由此可知准确答案为
easily.

17.词汇搭配题.分析可知,本句话中的主语passengers with
heart disease __17__ experience chest pains.其中心语为
pas sengers,其后为其定语,由experience并考察四个选项,确定应该
选择used to,意思为过去习惯于…,过去经常… .

18.词汇搭配题.分析本句话__18__ common in-flight problem
is deep venous thrombosis.注意到句中的problem和is,考察四 个选
项,首先能够排除any,因为前面没有one,所以能够排除other和
another.所以准确答案为one.

19.语境题.前面句子讲在飞行中的一个常见问题是所谓的经济舱
综合症,再分析本句话__19__ happens, don’t panic....发生,都不
要恐慌.句中的__19__ hap pens为让步状语.因为此处为特指经济舱综
合症所以能够排除whatever,所以能够确定准确 答案为whenever.

20.语境题.分析本句话flights with at __20__ one attendant
are starting to install emergency medical kits to treat heart
attacks.注意到句中的one attendant,由此能够确定应该选择at
least,表示至少.
