(2013·高考四川卷,E)Fear may be felt in the heart as well as in the headaccording to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.

Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting(收缩) and pumping blood around their bodiescompared with the point when the heartbeat is relaxed.Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful eventdepending on which point it is at in its regular cycle of contraction and relaxation.

Sarah Garfinkel at the Brighton and Sussex Medical School said“Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”

The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces.Dr Garfinkel said“The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus our hearts can also affect what we see and what we don’t seeand guide whether we see fear.”

To further understand this relationshipthe scientists also used a brain scanner(扫描仪) to show how the brain influences the way the heart changes a person’s feeling of fear.

“We have found an important mechanism by which the heart and brain ‘speak’to each other to change our feelings and reduce fear”Dr Garfinkel said.

“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reducedwe may be able to develop more successful treatments for anxiety disordersand also for those who may be suffering from serious stress disorder.”

1.What is the finding of the study?

AOne’s heart affects how he feels fear.

BFear is a result of one’s relaxed heartbeat.

CFear has something to do with one’s health.

DOne’s fast heartbeats are likely to cause fear.

2.The study was carried out by analyzing________.

? Avolunteers’ heartbeats when they saw terrible pictures

? Bthe time volunteers saw fearful pictures and their health conditions

? Cvolunteers’ reactions to horrible pictures and data from their brain scans

? Ddifferent pictures shown to volunteers and their heart?brain communication

3.Which of the following is closest in meaning to“mechanism” in Paragraph 6?

AOrder. BSystem.

CMachine. DTreatment.

4.This study may contribute to________.

? Atreating anxiety and stress better

? Bexplaining the cycle of fear and anxiety

? Cfinding the key to the heart?brain communication

? Dunderstanding different fears in our hearts and heads

 

【答案】

1.A

2.C

3.B

4.A

【解析】本文是一篇说明文。本文讲述了科学家通过研究揭示了恐惧与心脏和大脑的关系。

1.

2.2】解析:选C。由文章第四段和第五段可知,实验是通过分析志愿者对可怕图片的反应和他们的大脑扫描数据来进行的。A志愿者看到可怕图片时的心跳太片面;B项中提到了身体健康状况,而文章中并没有提及,故排除;D项中的heart?brain communication是在实验后提到的,故也排除。

3.3】解析:选B。结合上文的实验可知,mechanism所在句句意为:我们已经发现了一个重要的(身体内的)机制,通过它心脏和大脑可以互相交流来改善我们的情绪并减少恐惧。故只有Bsystem“体系,系统mechanism意思相近。order“顺序,命令machine“机械,机器treatment“治疗

4.4】解析:选A。推理判断题。由最后一段中的...we may be able to develop more...disorder.可知这个研究对治疗焦虑和压力有好处。所以选A项。

(2013·高考四川卷,B)On a sunny day last AugustTim heard some shouting.Looking out to the sea carefullyhe saw a couple of kids in a rowboat were being pulled out to sea.

Two 12?year?old boysChristian and Jackrowed out a boat to search for a football.Once they’d rowed beyond the calm watersa beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for it and the boat was out of control.

Tim knew it would soon be swallowed by the waves.

“Everything went quiet in my head”Tim recalls(回忆)“I was trying to figure out how to swim to the boys in a straight line.”

Tim took off his clothes and jumped into the water.Every 500 yards or sohe raised his head to judge his progress.“At one pointI considered turning back” he says.“I wondered if I was putting my life at risk.”After 30 minutes of strugglinghe was close enough to yell to the boys“Take down the umbrella

Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowingbut the waves were almost too strong for him.

“Let’s aim for the pier(码头)”Jack said.Tim turned the boat toward it.Soon afterwardwaves crashed over the boatand it began to sink.“Can you guys swim”he cried.“A little bit”the boys said.

Once they were in the waterTim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys’faces.

“Are we almost there”they asked again and again.“Yes”Tim told them each time.
