German researchers have___1___a new generation of defibrillators and earlywarning 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 pa- tients 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 automat-ically 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 an 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 indi- vidual 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.3._________A: are causedB: causedC: are to causeD: have been causing
选项 3._________
A: are caused
B: caused
C: are to cause
D: have been causing
答案 A
解析 come up with有“引起，产生，发明”的意思，符合上下文的意义。所以答案为B。
Protection后面跟介词from或against，意为“起保护作用以免于……”，其他介词均不合适。所以答案为D。
此处的谓语动词必须使用被动语态，因为主语many of those Cases指的是“病人”, “病例”，那就应该是“被引起的”，所以答案为A。
此处需要填的副词应该表示“已经”，完成时态的谓语已经起了提示作用。所以答案为D。
从上下文看，只有C项“威胁生命”合适。
take on表示“承担”，符合上下文意思，其他三个选项分别为“接受，接收 (A项）”,“效仿（B项）”和“消减（D项）”。所以答案为C。
A和B均有“能够”的意思，但用法不同：capable of(doing)sth./able to do sth.，所以答案为A。
上下文的意思是“……的血液流通问题和即将发生的心脏病”，后面这一部分为前面这个空格暗示了必须填入B项acute。
前面谓语动词renders的意思相当于make，后面要接复合宾语，这里缺少一个宾语补足语，因此只有D是答案。
A和B分别指最大量，最小量或最高值，最低值，而选项C和选项D则指多数和少数，由于前面已有overwhelming（压倒性的）提示，所以只能选C项majority。
take…into account是固定短语，意为“考虑，重视”。所以答案为B。
make use of是固定短语，意义为“利用”。所以答案为A。
四个选项中A和B均是“同样地”,C位于句首对表示“否则的话”，这些与上下文所要表达的意义均不吻合，因为前面并没有提到什么方法可以作比较，因此答案为D 项In the way“用这种方法”。
base sth.on/upon是固定短语，表示“把……建立在……基础上”，此处用过去分词的短语作为old Study的定语。所以答案为C。
此处空白需要填上一个能引导宾语从句的连接词，从宾语从句的结构来看，它的句子是完整的，所以只需填that作为连接词就可以了。所以答案为C。
