• 20．They say music is universal，and it seems to be true since wherever we go，we see people listening，playing or dancing to it.We tend to think that music is larger than our cultural differences and shows the deeper connections between us.
     But according to a recent study published in the journal Current Biology，music doesn't speak to everyone.There is a condition，the researchers argue，called "musical anhedonia".They say that those who have this condition lack the ability to experience pleasure from music.
     For the study，30 people listened to the same，mostly classical music pieces.They were then asked to complete a questionnaire on how they felt about the music.At the same time，the researchers measured their heart rate and skin reaction，which are considered physiological measures of emotion.
     According to the researchers，most of the people in the study got pleasure from the music.They had a quicker heartbeat and sweated more.However，a small number had very little and even no pleasant feeling while they listened.These people had none or very few of the physical signs the others in the study experienced.
     The researchers say that this means people have different abilities to enjoy music and that "there are people who specifically can't enjoy music at all"，study author Josep Marco-Pallres of the University of Barcelona in Spain told Live Science.
     To study the condition further，another group of scientists，at Columbia University，US，researched brain activities.They found that the key is the blood flow to the reward system in the brain.
     "People who got less pleasure from music had lower blood flow to areas involved in the reward system of the brain when listening to music， " reported the Daily Mail.
     The lower blood flow makes it more likely that the brain's "reward system" will not be active.Thus，it will produce less of the "pleasure chemical" dopamine.As a result，people get less pleasure from music.
     If the research is correct，according to National Public Radio，there are simply people who just don't get music.They may get pleasure from many things，but a good song isn't one of them.

  B．They like to listen to certain types of music.

  A．To learn how music influences people's emotions.
  B．To understand the relationship between music and the body.
  C．To learn what music people love the most.
  D．To see whether music works in the same way for all people.
  （3）What happened to the participants when they listened to music？

  
  A．Those who enjoyed music had more dopamine produced.
  B．Those who enjoyed music had slower blood flow.
  C．All of them had faster heartbeat and sweated more.
