【题目】Passage 3

Restaurant chefs, home cooks, and foodies — people who love good food — often say that we eat with all of our senses.

First, we use our sense of sight to appreciate how a meal is presented, either on a dinner plate or a dining table. 1 Additionally, with our sense of smell, we breathe in the mouth-watering smell rising up from the meal. Finally, we enjoy the food with our sense of taste.

But does sound also affect our dining experience? A new report from researchers at Brigham Young University said yes. Hearing is often called ＂the forgotten food sense.＂ says Ryan Elder, and assistant professor of marketing at Brigham Young University. 2 On the other hand, watching loud television or listening to loud music while eating can hide such noises. And this could lead to overeating.

During the experiments, the test subjects wore headphones and listened to noise at either a high or low audio level. 3 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. 4 The researchers are calling this the ＂crunch effect＂, which they admit may not seem like much at one meal. But over a week, a month, or a year, all that food can really add up. So hearing the sound of eating /span>does reduce the amount of food you consume.

5 Hearing the noises of your meal as you eat could also help you to be more mindful of the experience and perhaps help you to enjoy it more.

A. In fact, beautiful food is healthier than food that doesn’t look appealing.

B. But besides not overeating, there is another benefit.

C. And this may cause you to eat more than you would normally.

D. Then researchers gave them a hard snack: pretzels.

E. Our sense of touch can also be important when preparing or sharing food.

F. He notes that soft and sweet sound is thought to enhance the taste of food.

G. He says that if people notice the sound the food makes as they eat it, they might eat less.

＂Although I did not enjoy the violence of boxing, I was inteested in how one moved one’s body to protect oneself, how one used a strategy both to attack and retreat, ＂he wrote in his autobiography.
