【题目】Anger and other strong emotions (情感) can probably cause deadly heart beats in certain weak people,the US researchers said on Monday.
Earlier studies have shown that earthquake,war or even the loss of a World Cup Soccer game can increase chances of death from sudden cardiac arrest,in which the heart stops passing blood.
“It’s certainly been shown in all different ways that when you put people under pressure,sudden death will increase,” said Dr.Rachel Lampert of Yale University in New Haven,Connecticut.
“Our study starts to look at how this really has an effect on the electrical system of the heart,” Lampert said.
She and her assistants studied 62 patients with heart disease and ICDs that can discover dangerous heart beats and send an electrical shock to bring a normal heart beat back.
Patients in the study took part in an exercise in which they told a recent angry period while Lampert’s team did a test called TWave Alternant that measures electrical instability(不稳定性) in the heart.
Lampert said the team on purpose asked questions to get people to experience the angry period again.“We found in the lab that yes,anger did increase this electrical instability in these patients,” she said.
Next,they followed patients for three years to see which patients later had a cardiac arrest and needed a shock from their ICDs.“The people who had the highest anger were 10 times more likely than everyone else to have cardiac arrest,” she said.
Lampert said the study suggests that anger can be deadly,at least for people who are already weak /span>to this type of electrical disorder in the heart.
【1】From the passage we know cardiac arrest refers to ________.
A.someone who will be caught if he does something wrong
B.some place where you can show all your feelings
C.some disease that can kill people instantly
D.something used by patients in hospital
【2】The underlined word “this” in Paragraph 4 refers to “________”.
A.feelings of anger and pressure
B.games
C.feelings of happiness
D.hunger
【3】What did Lampert use to measure electrical instability of patients’ heart?
A.ICD and TWave Alternant test.
B.ICD and Cardic arrest.
C.Cardiac arrest.
D.The passage doesn’t tell us.
【4】The passage is mainly about ________.
A.new findings for heart disease
B.that anger really can kill a person
C.a new test of measuring heart blood
D.a study showing danger of heart beats
【答案】【1】 C
【2】 A
【3】 A
【4】 B
【解析】【1】推理判断题。文章第二段说到此前的研究表明,地震、战争甚至输掉一场世界杯足球赛都会增加cardiac arrest引起死亡的几率,并用非限制性定语从句解释,cardiac arrest是一种由心脏突然停止供血而引发的死亡,医学名为心源性猝死。
【2】推理判断题。上文主要讲述的是愤怒、压力等情绪会导致人猝死,因此,这段中作者要讨论的是这些情绪是如何导致人死亡的。所以这里的this指的应该是“愤怒”和“压力”。
【3】推理判断题。在第五段提到对62名心脏病患者进行了研究,这些患者都携有可以探测到危险性心律或心律失常,并能释放电刺激使心律恢复正常的植入式心脏除颤(ICD)。这是试验的辅助工具。在第六段提到研究小组让病人进行一项练习,即讲述最近发生的一件令他们生气的事情,同时通过一种名叫“T波交替”的试验来测量病人心电的不稳定度,这是一种方法。
【4】主旨大意题。美国研究人员称,对某些“脆弱”的人来说,愤怒可能会触发致命的心律失常。
