问题                         Scientists Develop Ways of Detecting Heart Attack
   German researchers have(1)a new generation of defibrillators and early warning software aimed at offering heart patients greater protection(2)sudden death from cardiac arrest.
   In Germany alone around 100,000 people die annually as a result of cardiac arrest and many of these cases(3)by disruption to the heart’s rhythm. Those most at risk are Patients who have(4)suffered a heart attack and for years the use of defibrillators has proved useful in diagnosing(5)disruptions to heart rhythms and correcting them automatically by intervening within seconds. These devices(6)a range of functions such as that of pacemaker.
   Heart specialists at Freiburg’s University Clinic have now achieved a breakthrough with all implanted defibrillator(7)of generating a six-channel electrocardiogram(ECG) within the body. This integrated system allows early diagnosis of(8)blood-flow problems and a pending heart attack. It will be implanted in patients for the first time this year. Meanwhile, researchers at the Fraunhofer Institute for Applied Mathematics in Kaiserslautern have developed new computer software that renders the evaluation of ECG data(9).
   The overwhelming(10)of patients at risk will not have an implanted defibrillator and must for this reason undergo regular ECGs. "Many of the current programs only(11)into account a linear correlation of the data. We are, however, making use(12)a non-linear process that reveals the chaotic patterns of heart beats as an open and complex system." Hagen Knaf says."(13)changes in the heart beats over time can be monitored and individual variations in patients taken into account." An old study of ECG data, based(14)600 Patients who had suffered a subsequent heart attack, enabled the researchers to compare risks and to show(15)the new software evaluates the data considerably better.
选项 A、Similarly
B、In this manner
C、Otherwise
D、In this way
答案D
解析 四个选项中A、B项均是“同样地”的意思，C项放句首时，一般是“否则的话”的意思，均与上下文所要表达的意思不吻合，因为前面并没有提到什么方法可做比较，故只有D项“用这种方法”比较合适。
