Fear may be felt in the heart as well as in the head, according 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(向---送出) blood around their bodies, compared 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 event, depending 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. So our hearts can also affect what we see and what we don't see - and guide whether we see fear."
To further understand this relationship, the 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 reduced, we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder."
小题1:What is the finding of the study?
A.fear has something to do with one's health.
B.fear is a result of one's relaxed heartbeat.
C.One's heart affects how he feels fear.
D.One’s fast heartbeats are likely to cause fear.
小题2:When are people more likely to feel a sense of fear ?
A.When the heartbeat is relaxed.
B.When their hearts are contracting.
C.When people are tired.
D.When people are happy.

A.the time volunteers saw fearful pictures and their health conditions
B.volunteers' heartbeats when they saw terrible pictures
C.volunteers' reactions to horrible pictures and data form their brain scans
D.different pictures shown to volunteers and their heart-brain communication
小题4:Which of the following is closest in meaning to "mechanism" in Paragraph 6?
A.Order.B.Machine.C.Treatment.D.System.
小题5:This study may be useful to _______.
A.treating anxiety and stress better

试题分析:科学家通过研究总结出一个人的心脏影响他对恐惧的感受,心脏收缩舒张时比放松时更可能去感受恐惧;这个研究是通过分析志愿者对恐怖图片的反应和对大脑扫描的数据来实现的,并且科学家们发现了一个重要的规律就是通过心脏和大脑的对话来改变我们的感受并减小恐惧,这个规律也可以运用在焦虑和压力的治疗方面。
小题1:推理判断题。根据短文第二段描述Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.,可知心脏能够影响大脑对恐惧事件的反应,取决于心脏的有规律的收缩和舒张。所以一个人的心脏影响他对恐惧的感受,故选C。
小题2:细节理解题。根据短文第二段描述 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(向---送出) blood around their bodies, compared with the point when the heartbeat is relaxed.,可知当心脏收缩舒张时比放松时更可能去感受恐惧,故选B。
小题3:推理判断题题。根据短文段描述,可知这个研究是通过分析志愿者对恐怖图片的反应和对大脑扫描的数据来实现的,故选C。
小题4:词义猜测题。根据短文描述We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear,可知科学家们发现了一个重要的规律就是通过心脏和大脑的对话来改变我们的感受并减小恐惧,所以mechanism的意思是“规律”,故选D。
小题5:细节理解题。根据短文第一段描述we may be able to develop more successful treatments for anxiety disorders, and also for those for those who may be suffering from serious stress disorder.,可知通过上述研究,可以让焦虑,有压力的治疗变得更成功,故选A。

There are not many red-crowned cranes in the world, but every winter you can see some in the Red-crowned Crane Nature Reserve in the Yellow Sea Wetlands.

One night, I felt very tired, so I sat outside in a small park and began to eat a small piece of bread.
