I wondered what I would do if 4 with a real mid?air medical emergencywithout access 5 a hospital staff and the usual emergency equipment. So 6 the New England Journal of Medicine last week 7 a study about in-flight medical events, I read it 8 interest.
The study estimated that there are a(n) 9 of 80 in-flight medical emergencies on U.S. flights every day. Most of them are not 10; fainting and dizziness are the most frequent complaints. 11 13% of themroughly four a dayare serious enough to 12 a pilot to change course. The most common of the serious emergencies 13 heart trouble, strokes, and difficult breathing.
Lets face it: plane rides are 14.For starters, cabin pressures at high altitudes are set at roughly 15 they would be if you lived at 5,000 to 8,000 feet above sea level.

答案與解析：
1.A call有召喚、召集之意。在飛機上有人生病了，就要call a doctor。其他幾個選項，address指稱呼某人，inform是告訴的意思，而survey則指調查，都不符合文意。
2.A 此題考查詞匯和上下文理解。飛機上有人突然暈倒是一件突發(fā)事件，即事故，所以，此題選擇accident。incident指事件，disaster指災難，用在這里，言過其實。
3.D 此題考查上下文理解。這種事情發(fā)生的頻率到底有多高呢?作者感到很好奇。四個選項中，只有how often連起來表示頻率。故選D。
4.A 此題考查詞匯和上下文理解。經觀察，四個選項都加了ed表示被動語態(tài)。A、B、C、D選項的意思分別是面對、對待、識別、假設。作者由文章開頭的小事故聯(lián)想到如果真在半空中遇到嚴重的醫(yī)療事故，那自己將怎樣面對。根據(jù)文意，此處應選confronted。
5.B 此處考查詞組的固定搭配access to有權使用、接近。作者想知道在沒有醫(yī)院醫(yī)護人員和緊急醫(yī)療設備的情況下如何應對突發(fā)醫(yī)療事故。
6.C 此題考查上下文連接。文意表達的是：當上周的醫(yī)療周刊登出了關于機上醫(yī)療事件的研究時，我懷著巨大的興趣去讀了。所以，這里選when。
7.D 參照上文，周刊最可能發(fā)出的動作應該是出版。故選published。
8.C 本題要表達帶著興趣，伴隨用with。
9.B 此處考查上下文理解。作者查出了美國平均每天機上突發(fā)醫(yī)療事件的次數(shù)，而數(shù)據(jù)統(tǒng)計一般都會用平均數(shù)字來說明問題。所以，這里選average。其他選項，a sum of、an amount of、a number of分別表示一筆、一些(后加不可數(shù)名詞)、一些(后加可數(shù)名詞)。
10.D 病痛嚴重與否用serious表達。所以，這里選serious。
11.C 此處答案需從后文查找。能使飛行員改變航道的病與輕微的暈厥進行對比，所以這里的連詞是but。
12.A 此處重點考查詞匯的細微區(qū)別。inspire(鼓舞)和encourage(鼓勵)顯然不符合要求;require(要求)常用于按照規(guī)定、慣例、環(huán)境等提出的要求去做某某人做某事。根據(jù)原文的意思，機上有重病患者，這種情況要求飛行員改變航向，挽救生命。因此，選擇D答案。
13.A 作者在此處舉例說明了什么病是嚴重的突發(fā)病。這里的空缺結合選項可知，表達包括的概念。contain指容納、包含，只有include最符合題意。
14.D 此題考查上下文理解。四個選項意思是：enjoyable(輕松愉快的)、stimulating(刺激的)、tedious(乏味的)、stressful(壓力大的)。從下文可知，飛機要飛到海拔5000-8000英尺，這個過程并不是輕松愉快的，既能引發(fā)病痛，也絕不是乏味的這樣簡單，所以，這里要選擇stressful。
15.B此處考查疑問代詞。原文意思為：對于初乘航班者，高空里機艙壓力相當于生活在海拔5000-8000英尺高度的氣壓。what 指代 pressures，故選B。
16.C 此題考查上下文理解和詞匯。從下文可知，此處與有心臟病的乘客乘坐飛機進行對比。意即，大多數(shù)健康的人能輕松應付。選擇easily。
17.B 參照上文。由于此文是一個客觀描述，所以，心臟病患者乘客在缺氧情況下應該可以/可能感到胸痛。選may。
18.D 前文中提到chest pains，所以這里應該用另外一種(another)，故選D。
19.A 選A無論發(fā)生什么。
20.C 此題考查固定搭配at least。
