【正确答案】 C

【答案解析】[听力原文]
   Elder is an assistant professor of marketing at Brigham Young University's Marriott School of Management. He says that if people notice the sound the food makes as they eat it, they may eat less.
   On the other hand, watching loud television or listening to loud music while eating can hide such noise. And this could lead to overeating.
   For the study, the researchers wanted to test whether the sounds of eating—chewing, chomping and crunching—had any effect on how much a person ate.
   During the experiments, the test subjects wore headphones and listened to noise at either a high or a low audio level. Then researchers gave them a crunchy snack: pretzels. The study found that subjects who listened to the higher volume noise ate more pretzels than those with the low audio levels.
   Elder says that when hiding the sounds of eating, like when you watch television or listen to loud music while eating, we take away the sense of hearing. And this may cause you to eat more than you would normally.
   Q: On what would Elder agree?
埃尔德是美国杨百翰大学麦里特管理学院的营销学助理教授。他称，如果人们能注意到自己吃东西时发出的声音，他们可能会吃得少一些。
   另外一方面，如果边吃东西边看电视，而电视声音又大，或者边吃东西边听音乐，而音乐声音又响，则吃东西的声音就会被掩盖。这可能会导致饮食过量。
   对于这项研究，研究人员想要测试吃东西发出的声音——咀嚼、咬牙、嘎吱作响——是否对一个人的饮食量有任何影响。
   在实验期间，实验对象戴上耳机，分别听着高音量或低音量的嘈杂声。随后，研究人员给他们吃一种脆食——椒盐脆饼干。研究发现，听高音量的实验对象比听低音量的实验对象吃得更多。
   埃尔德称，吃东西的声音如果被掩盖，比如在吃的过程中看电视或听很响的音乐，我们就会剥夺听觉。而这可能使得你比通常情况下吃得更多。
   利用播放答题导语的时间，快速浏览每道小题的四个选项。由两道题选项中的关键词sounds of eating、eat less、enjoy eating more、background music、a crunchy snack等判断，该则新闻涉及吃东西与声音的关系，可能报道的是一项研究成果。
   四个选项均有would，均表明一种设想的情况，可判断问题很可能是关于人物观点的。听到问题后立刻回忆所听内容，结合选项作答。
   新闻开头简单介绍了埃尔德，随后指出，他称，如果人们能注意到自己吃东西时发出的声音，他们可能会吃得少一些，由此可见，C项是埃尔德赞同的观点，故本题选C。
