问题 Scientists Develop Ways of Detecting Heart Attack
German researchers have come up with a new generation of defibrillators (除颤器)and early-warning software aimed at offering heart patients greater __(51) from sudden death from cardiac arrest (心脏停搏）In Germany alone, around 100，000 people die annually__ (52) a result of cardiac arrest and many of these cases are caused by disruption to the heart’s rhythm. Those most at_(53) are patients who have already suffered a heart attack, and for years the use of defibrillators has proved useful in_(54) life-threatening disruptions 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,心电图）within the body. This integrated system allows_(57) diagnosis of severe blood-flow problems and a pending (艮P将发生的）heart attack. It will be implanted in _(58) for the first time this year. Meanwhile, researchers at the Fraunhofer Institute
for Applied Mathematics in Kaiserslautern have developed new computer software that _(59) the evaluation of ECG data more precise.
The overwhelming majority of patients at risk will not have an implanted defibrillator and must for this__(60) undergo regular ECGs. “Many of the current programs only take into (61) a linear correlation of the data. We are, however, making use of a
non-linear process (62) reveals the chaotic patterns of heart beats as an open and complex system，，，Hagen Knaf says. “In this way changes in the heart (63) over time can be monitored and individual variations in patients taken into account.，’ An old study of ECG data, based upon 600 patients who had_(64) a subsequent heart attack,enabled the researchers to compare risks and to show that the new software evaluates the (65 ) considerably better.
选项 A purpose
B reason
C treatment
D chance
答案B
解析本题考查短语的含义。本句的意思是“绝大多险中的患者没有植入性除颤 器，因此必须接受普通的心电图A项for this purpose“为了这个目的”，B项for this reason是“为此、由于这个原因”，C、D选项所以答案是B。
