题目

阅读理解 Listening to music while studying or doing homework is a very common habit among students. The research in 1972 showed that there was an increase in the performance of workers when listening to music. However, this research was limited, and was only used to study a very specific and representative working environment at the time-factories. Workforce tasks were repetitive, predictable and boring. But what about the complex (复杂的）and creative jobs? What about studying complex academic programs? It seems that when the work at hand forces us to really focus on what we arc doing, the presence of the music is a burden that we must avoid. For example, the research published in Psychological Reports found that when some volunteers had to choose a piece of music and listen to it while studying or doing homework, they performed worse than those who did not choose and simply accomplished the task without listening to music. In other words, even though music is used for studying, it may just be because you like the music, not because it improves memorization and learning outcomes. Why is it not good to listen to music while studying? The answer lies in two concepts: multitasking (多任务化）and attentional concentration. Multitasking is the ability to perform more than one task at the same time and is closely related to working memory. This type of memory is responsible for keeping in mind the elements with which we woric in real time. Attentional concentration is how the brain directs mental processes toward solving some problems and not others. When we focus on something, we are using a large part of our nervous system to fix it. For this, you have to pay the price for neglecting other functions. （1） What was the disadvantage of the research in 1972? A . A short length of time. B . A shortage of researchers. C .
