It’s common knowledge that music can have a powerful effect on our emotions. In fact, since the 1930s, music therapists have relied on music to calm patients and help control pain. Now psychologists are confirming that music can also help relieve depression and improve concentration. For instance, in a recent study, 50 surgeons were given some high-stressed math problems to solve. They were divided into three groups: one worked in silence, and in another, the surgeons listened to music of their choice on headphones; the third group listened to classical music chosen by the researchers. The results of the study may surprise you. The doctors who got to choose their own music experienced less stress and scored better than the others. One possible explanation is that listening to the music you like stimulates Alfa waves in the brain, increases heart rate and expands breathing. That helps to reduce stress and sharpen concentration. Other research suggests a second relationship between music and the brain: By examining the blood of students after they listened to a variety of classical music selections, researchers found that some students showed a large increase in endorphin, a natural pain reliever. This supports what music therapists have known for years: Music can help revitalize or calm the patient. Questions 26 to 29 are based on the passage you have just heard.
选项
A、To drive the train after it is started automatically.
B、To start the train and to drive it when necessary.
C、To take care of the passengers on the train.
D、To send commanding signals to the command spot.
答案
B
解析
由短文中提到的on the train(= On the Victoria Line train),there is only one worker.If necessary,this man can drive the train. But usually he just starts it;it runs and stops by itself可知,在维多利亚线运营的火车上,工人只需启动火车,并在必要时进行驾驶,B项正确。
