三、完形填空
Music helps us exercise, but why does it have this effect? Scientists say there are some 1.
The first is simple: music distracts（使……分心）us. When we listen to a song we like, our brain pays attention to the music. 2 we exercise for 20 minutes, for example, our body may be tired. But because of the music, we may not feel this right away. 3, we will exercise a little longer.
Music can also motivate（激励）us. When we hear dance music, for example, we 4 start to move to the beat. An upbeat（欢快的）song also makes us feel happier. This gives us energy and helps us 5 longer.
However, according to a new study by scientist Tom Fritz, this is only part of the explanation. In the study, at first, Fritz divided 61 people into several groups. 6 they all exercised twice. The first time, each group worked out for six minutes 7 listening to music. The second time, they exercised for six minutes on special Jymmin machine. On these machines, each group made music as they moved. In the end, 53 of the 61 people said the 8 thing: they felt less tired when they exercised on the Jymmin machines.
How does Fritz explain this? Fritz said that maybe people did better on the Jymmin machines because they had more control. People created the beat. 9 could make it go faster or slower. Also, each group was making music together and having fun. In the future, Fritz wants to 10 if Jymmin exercise can help with some illnesses. For example, it may even be a good way to treat depression（抑郁症）.
