Scientists Develop Ways of Detecting Heart Attack

　　German researchers have come up with a new generation of defibrillators and early-warning software aimed at offering heart patients greater51 from sudden death from cardiac arrest.

In Germany alone around 100,000 people die annually52a result of cardiac arrest and many of these cases are caused by disruption to the heart's rhythm. Those most at53 are patients who have already suffered a heart attack, and for years the use of defibrillators has proved useful in.54life-threatening disruption to heart rhythms and correcting them automatically by intervening within seconds. These devices 55 on a range of functions, such as that of pacemaker (起搏器).

Heart specialists at Freiburg's University Clinic have now achieved a breakthrough with an implanted defibrillator 56 of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows57diagnosis of acute blood-flow problems and a pending heart attack. It will be implanted in58 for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that59the evaluation of ECG data more precise.

The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this60undergo regular ECGs. "Many of the current programs only get into61 a linear correlation of the data. We are, however, making use in a non-linear process62reveals the chaotic patterns of heart beats as an open and complex system," Hagen Knaf says, "In this way changes in the heart63 over time can be monitored and individual variations in patients taken into account." An old study of ECG data, based upon 600 patients who had64a subsequent heart attack, enabled the researchers to compare risks and to show that the new software evaluates the65 considerably better.

参考答案：

51.C。本题考查句意和固定搭配。题干：德国研究者们发明了新一代的除颤器和预警软件，旨在为心脏病人提供更多保护，使他们免遭心脏停止导致的突然死亡的风险，“使……免受”的固定用法为protection from，其他选项无此用法。故C选项为正确答案。

52.B。本题考查固定搭配。题干：仅在德国每年就有10万人死于心脏停止。其中大部分是由于心律中断导致的。as a result of为固定搭配，意为“由……导致的”。故B是正确答案。

53.D。本题考查上下语义。题干：危险最大的是那些已经犯过一次心脏病的病人。at last意为“最后”，at aU意为“根本;究竟”，常用于否定句，at once意为“立刻，马上”， at risk意为“处于危险中”，可知只有D选项at risk符合句意。

54.C。本题考查句意。题干：……几年来除颤器被证实在诊断心律中止和几秒钟内实施自动干涉调整心律中是有用的。四个选项中能与“life-threatening disruption to heart rhythms”搭配的只有C选项的diagnosin9，意为“诊断”,其他选项填入此处都说不通。故C是正确答案。

55.C。本题考查动词固定搭配。“承担，呈现”的固定用法为take on。故C是正确答案。

56.D。本题考查旬意。题干：这种除颤器可以在体内产生六个频道的心电图。worthy of意为“值得”，full of意为“装满，全神贯注于……的”，proud of意为“为……而感到骄傲”，capable of意为“有……能力的，可以……的”，只有capable of放入此处符合旬意，因此D为正确选项。

57.D。本题考查句意。本文一直在讲心脏病的早期诊断，所以只有D选项符合句意。

58.C。本题考查上下文语义。空格所在的句中“it”指代上文的“an implanted defibrillator”，而这个仪器就是为病人开发的，所以C选项patients符合上下文语义。

59.D。本题考查句意。题干：同时，凯瑟劳特的弗劳胡佛实用数学学院的研究者开发了一种新计算机软件。这种软件使心电图数据更加准确。carry意为“携带，支持”，have意为“有”，require意为“需要”，make意为“使得”中。只有make具有“使得”的意思，符合句意，因此D为正确选项。

60.A。本题考查上下文语义。前面提到大部分有风险的患者不能用内置除颤器，这是因。后面提到必须接受常规的心电图检查，这是果。所以A选项reasons“原因，理由”为正确答案。

61.A。本题考查固定搭配。题干：目前的许多计划只把数据的线形关系考虑在内。“把……考虑在内”的固定用法为get into与account搭配，而且后文也提到了“taken into account”。故A为正确选项。

62.B。本题考查定语从句。空格后的“reveals the chaotic patterns ofheart beats as an open and complex system”整个句子做前面名词process的定语，这个定语从句缺少主语，因此that正确。

63.A。本题考查固定搭配。“心脏跳动”的英语表达为heartbeats。故A为正确选项。

64.A。本题考查句意。题干：“……一个基于600位犯心脏病患者的以前的心电图数据……”。suffer意为“遭受”，launch意为“发射”，avoid意为“避免”，start意为“开始”，只有suffer符合整个句子的意思。故A为正确选项。

65.D。本题考查上下文语义和句意。题干：……结果显示新软件明显能更好地处理心电图数据。option意为“选择”，method意为“方法”，proposal意为“建议”，data意为“数据”，只有data符合上下文的意思，而且data一词多次出现在本段中，故D为正确选项。
