In some children who go blind, certain parts of the brain that normally control vision appear to switch jobs and focus instead on sound, a new study has found.
The study, by researchers at the University of Montreal, involved 7 adults who could see and 12 adults who had lost their vision when they were children. Each participant sat in a room with 16 loudspeakers at different locations. The room was designed so that there were no echoes. During the experiment, the speakers irregularly produced sounds. Participants had to point to where the sounds were coming from. Meanwhile, the researchers monitored blood flow in the brains of the participants to see which brain structures were working during the task.
The results showed that 5 of the blind participants were very good at pointing to where sounds were coming from. In these people, blood flow increased in the visual cortex — an area at the back of the right side of the brain. This part of the brain is usually associated with vision. The other 7 blind participants showed no increase in activity in the visual cortex. These people didn’t do very well at picking out where sounds were coming from. Now, the researchers are looking at whether these people have gained an enhanced sense of touch instead of sound to replace their lost vision. The scientists say that their study shows how adaptable parts of the brain can be.
Questions 32 to 35 are based on the passage you have just heard.
32. What is the purpose of the experiment described in the passage?
33. What were the participants of the experiment asked to do?
34. During the experiment, why was blood flow in the brains of the participants measured?
35. What can best summarize the main idea of the passage?
选项
A、Tell the difference between 16 sounds.
B、Take down the time each sound lasted.
C、Identify the direction the sound came from.
D、Detect the number of the loudspeakers.
答案
C
解析
选项均以原形动词开头以及选项中重复出现的sound表明,本题可能考查与声音有关的行为动作。由短文中提到的Participants had to point to where the sounds were coming from可知,参与者被要求辨别出声音的方向,故答案为[C]。
