Music helps us exercise. Why does it have this effect? 54
The first is simple:Music distracts(使分心）us. Our body might be tired after we exercise for 20 minutes. But we may not feel this at once because we are listening to music. 55
Music also cheers us up. When we hear dance music, for example,we naturally start to move to the beat. 56 This gives us energy and helps us exercise longer. In a study, Fritz put 61 people in small groups. He tested them on a special machine. One time, each group did sports while listening to music for six minutes. Another time they exercised for six minutes. In the end,53 of the 61 people said the same thing: 57 When we exercise and make music with other people, doing sports seems to be easier.
58 "Maybe people did better on the special machines because they had more control," he says. People created the beat. They could make it go faster or slower. Also,the activity was social. Each group was making music together and having fun.
A. A cheerful song makes us feel happier.
B. We can exercise a little longer.
C. How does Fritz explain this?
D. Experts say there are two main reasons.
E. They felt less tired when they exercised with music.
54. 55. 56. 57. 58.

54. D 55. B 56. A 57. E 58. C
