第十三篇 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 protection1___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 an implanted defibrillator___7_____of generating a six-channel electrocardiogram (ECG) within the body. This integrated system allows early diagnosis of___8____blood-tlow 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 system2." Hagen Knaf says,“____13___ changes in the heart beats over time can be monitored and individual variations in patients taken into account3.”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.
词汇：
defibrillator n去纤颤器
overwhelming adj.压倒的
pending adj.追近的，即将发生的 pacemaker n起搏器
cardiac adj.心脏的 linear adj.线(性)的
implant vt植入 arrest n停止
electrocardiogram心电图
render 提出…… correlation n相互关系
disruption n.中断 chaotic adj. 混乱的
注释：
1…and early-warning software aimed at offering heart patients greater protection. ：本句中aimed at是过去分词短语，作前面两个名词的定语，原意是“把目标瞄准……”，此处可译为 “旨在为心脏病人提供更多保护的早期预报软件”。
2 anon-linear process that reveals the chaotic patterns of heart beats as an open and complex system:这里that引导的是process的定语从句。as是介词，open在此可译为“直观的”。本句的意思是：……能够将心脏跳动的混乱模式作为一个直观而又复杂的系统揭示出来的非线性处理方法。
3 and individual variations in patients taken into account:这里在taken之前省略了与上句相同的情态动词和助动河can be。

8 A chronic B acute C recurrent D persistent
9 A precisely B more precisely C precision D more precise
10 A maximum B minimum C majority D minority
11 A get B take C bring D fetch
12 A of B with C for D in
13 A Similarly B in this manner C Otherwise D In this way
14 A in B for C upon D with
15 A what B where C that D when
答案与题解：
L B come up with字面意思是“和……一起来到世上”，有“引起;产生;发明”的意思，符合上下文意思。A项是“走近”，C项是“到达”、“符合”，D项是“遇到(困难)”，均不合适。
2 D protection与它的动词protect -样，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。
3 A此处的谓语动词必须使用被动语态，因为主语many of these cases指的是“病人”、“病例”，那就应该是“被引起的”，故其他选项使用主动语态都不合适，况且后面by的介词短语已是一个明显的提示。
4 D此处要填的副词应该表示“已经”的意思，完成时态的谓语已经起了提示作用，A项、B
项都是“容易”的意思，C项是“经常”的意思，均不合适。
5 C从上下文看，只有C项“威胁生命的”合适，A、B、D三项分别为“致病的”、“促进健康的”、“纠错的”，均不对。
6 C take on表示“承担”，符合上下文意思，其他三项分别为“接受，接收” 7 A A项和B项均有“能够”的意思，但用法不同，capable of (doing) sth，而able to do sth，故A项才是答案。C、D项均是“熟练的，有技能的”，但后面都要用介词in，且在此处词义也不舍适。 8 B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 个空白暗示了必须填acute，因为其他三个选项“慢性的”、“复发性的”、“持久性的”，都与这个语境不协调。 9 D填这个空时要注意前面谓语动词在这里的用法，它在这里的意思相当于make，后面要求复合宾语，这里缺一个宾语补足语，显然副词(A、B)和名词(c)均不适台在这里充当宾语补足语，故只有D项合适。 10. C选项A和B分别是指最大量、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，故只能用majority。 11. B take sth. Into account是固定短语，意为“考虑，重视”，其他几个动词都与 into account不搭配。 12 A make use of是固定短语，意为“利用”，其他介词都与其不搭配。 13 D 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，这些与上下文所要表达的意思均不吻合，因为前面并没有提到什么方法可作比较，故只有D项“用这种方法”比较合适。 14 C base sth. n/。p。n是固定短语，表示“把……建立在……基础上”，此处用过去分词短语作为old study的定语，除了on/upon以外，其他介词都与其不搭配。 15 C此处空白需要填that个能引导宾语从句的连接词。从宾语从句的结构看，它的句子是 完整的，所以只需填that作为纯粹连接词就行了，其他三项均要充当从句中的句子成分，且有一定意义，故不合适。
