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.

答案與解析：
1.A call有召喚、召集之意。在飛機(jī)上有人生病了，就要call a doctor。其他幾個(gè)選項(xiàng)，address指稱呼某人，inform是告訴的意思，而survey則指調(diào)查，都不符合文意。
2.A 此題考查詞匯和上下文理解。飛機(jī)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(zāi)難，用在這里，言過其實(shí)。
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(gè)選項(xiàng)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(jīng)觀察，四個(gè)選項(xiàng)都加了ed表示被動語態(tài)。A、B、C、D選項(xiàng)的意思分別是面對、對待、識別、假設(shè)。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(yán)重的醫(yī)療事故，那自己將怎樣面對。根據(jù)文意，此處應(yīng)選confronted。
5.B 此處考查詞組的固定搭配access to有權(quán)使用、接近。作者想知道在沒有醫(yī)院醫(yī)護(hù)人員和緊急醫(yī)療設(shè)備的情況下如何應(yīng)對突發(fā)醫(yī)療事故。
6.C 此題考查上下文連接。文意表達(dá)的是：當(dāng)上周的醫(yī)療周刊登出了關(guān)于機(jī)上醫(yī)療事件的研究時(shí)，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(yīng)該是出版。故選published。
8.C 本題要表達(dá)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(jī)上突發(fā)醫(yī)療事件的次數(shù)，而數(shù)據(jù)統(tǒng)計(jì)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(xiàng)，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(yán)重與否用serious表達(dá)。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(jìn)行對比，所以這里的連詞是but。
12.A 此處重點(diǎn)考查詞匯的細(xì)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(jī)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(yán)重的突發(fā)病。這里的空缺結(jié)合選項(xiàng)可知，表達(dá)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(gè)選項(xiàng)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(jī)要飛到海拔5000-8000英尺，這個(gè)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(jī)艙壓力相當(dāng)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(jī)進(jìn)行對比。意即，大多數(shù)健康的人能輕松應(yīng)付。選擇easily。
17.B 參照上文。由于此文是一個(gè)客觀描述，所以，心臟病患者乘客在缺氧情況下應(yīng)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(yīng)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。
