Question

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(收縮) 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(掃描儀) 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."

【解析】

試題分析：科學家通過研究總結出一個人的心臟影響他對恐懼的感受，心臟收縮舒張時比放松時更可能去感受恐懼；這個研究是通過分析志愿者對恐怖圖片的反應和對大腦掃描的數(shù)據(jù)來實現(xiàn)的，并且科學家們發(fā)現(xiàn)了一個重要的規(guī)律就是通過心臟和大腦的對話來改變我們的感受并減小恐懼，這個規(guī)律也可以運用在焦慮和壓力的治療方面。

1.推理判斷題。根據(jù)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.，可知心臟能夠影響大腦對恐懼事件的反應，取決于心臟的有規(guī)律的收縮和舒張。所以一個人的心臟影響他對恐懼的感受，故選C。

2.細節(jié)理解題。根據(jù)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(收縮) and pumping（向---送出） blood around their bodies, compared with the point when the heartbeat is relaxed.，可知當心臟收縮舒張時比放松時更可能去感受恐懼，故選B。

3.推理判斷題題。根據(jù)短文段描述，可知這個研究是通過分析志愿者對恐怖圖片的反應和對大腦掃描的數(shù)據(jù)來實現(xiàn)的，故選C。

4.詞義猜測題。根據(jù)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，可知科學家們發(fā)現(xiàn)了一個重要的規(guī)律就是通過心臟和大腦的對話來改變我們的感受并減小恐懼，所以mechanism的意思是“規(guī)律”，故選D。

5.細節(jié)理解題。根據(jù)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.，可知通過上述研究，可以讓焦慮，有壓力的治療變得更成功，故選A。
