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?".而第二句是讲自己曾经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accident,其意思为事故,意外的事情.本题有可能误选condition,这是由于受到中文表达的影响,只要分析上下文的语态,就可以排除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可以首先排除how many,再根据中文表达习惯,可以确定应该选择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,首先可以和介词with搭配,其次符合上下文的意思.由此可以确定应该选择confront.confront 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.由此可以确定正确答案为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,也可以表示某一段时间.在when引导的时间状语从句中,其谓语动词可以是延续性的,也可以是非延续性的,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在.另外,when和while的区别还在于:while引导的时间状语从句多用进行时态,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 England 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,由此可以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可以确定答案.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,由此可以确定第十题应该选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.由此可以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,首先可以构成*(动词) sb.to do sth.,其次还要符合上下埃文的意思.由此首先可以排除B和C两个选项.require比command的语气要弱,require只是要求,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 emergencies,后面是分述几种疾病,由此可以确定应该选择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可以确定答案.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.由此可以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.

16.语境题.本题的解答需要考查下一句话.由下句话开头的but可知,前后两个分句的意思是相反的.后面将由心脏病的乘客会由于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.由此可以推断出正常人可以很轻松的应对这种压力,由此可知正确答案为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passengers,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,首先可以排除any,由于前面没有one,所以可以排除other和 another.所以正确答案为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__ happens为让步状语.由于此处为特指经济舱综合症所以可以排除whatever,所以可以确定正确答案为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,由此可以确定应该选择at least,表示至少.
