【题目】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 and pumping 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.Thus, 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 who may be suffering from serious stress disorder.”

【1】What is the finding of the study? ________.

A. Fear is a result of one's relaxed heartbeat.

B. One's heart affects how he feels fear.

C. Fear has something to do with one's health.

A. volunteers' heartbeats when they saw terrible pictures

B. the time volunteers saw fearful pictures and their health conditions

C. volunteers' reactions to horrible pictures and data from their brain scans

D. different pictures shown to volunteers and their heart-brain communication

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

A. order B. treatment C. machine D. system

4This study may contribute to ________.

A. treating anxiety and stress better

B. explaining the cycle of fear and anxiety

【题目】 As Internet users become more dependent on the Internet to store information, are people remembering less? If you know your computer will save information, why store it in your own personal memory, your brain? Experts are wondering if the Internet is changing what we remember and how.

In a recent study, Professor Betsy Sparrow conducted some experiments. She and her research team wanted to know how the Internet is changing memory. In the first experiment, they gave people 40 unimportant facts to type into a computer. The first group of people understood that the computer would save the information. The second group understood that the computer would not save it. Later, the second group remembered the information better. People in the first group knew they could find the information again, so they did not try to remember it.

In another experiment, the researchers gave people facts to remember, and told them where to find the information on the Internet. The information was in a specific computer folder (文件夹). Surprisingly, people later remember the folder location (位置) better than the facts. When people use the Internet, they do not remember the information. Rather, they remember how to find it. This is called "transactive memory (交互记忆)"

According to Sparrow, we are not becoming people with poor memories as a result of the Internet. Instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. This doesn't mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing.

【1】What can we learn about the first experiment?

A. Sparrow's team typed the information into a computer.

B. The first group didn’t know where the information is.

C. The two groups remembered the information equally well.

D. The second group had a better memory of the information.

【2】In transactive memory, people ______.

A. know how to access huge amounts of information later.

B. learn how to organize small amounts of information.

C. organize huge quantities of information like a computer.

D. bear huge quantities of information in mind.

【3】What is the effect of the Internet according to Sparrow's research?

A. We are becoming more intelligent.

B. We are using memory differently.

C. We have poorer memories than before.

D. We need a better way to access information.
