Part II. TRANSCRIPT
How the speed of eating affects our health
Could eating fast make you gain more weight? Research suggests people who eat faster tend to have a higher body weight. So how fast are we talking? (Q1) It takes around 20 minutes from when we start eating for the brain to register that we’ve had enough. So if you’re rushing your meal, you might unwittingly overeat. (Q2) In one small study, people who ate the same meal in 24 minutes instead of six said they felt fuller with lower levels of the hunger hormone ghrelin found in their blood. And, they ate about 100 fewer calories’ worth of snacks three hours later. (Q3) Studies have also linked fast eating with higher rates of belly fat, blood pressure, and metabolic problems like type 2 diabetes. A small Japanese study found higher peaks of blood sugar in healthy women who took 10 minutes to eat a meal instead of 20. Consistently high blood sugar can lead to things like cardiovascular problems in people with and without diabetes. Now, if all this makes you want to eat more slowly, (Q4) nutritionists have some tips, like using smaller spoons, consciously chewing more, and taking a sip of water in between mouthfuls. Of course, if you’re worried your eating speed might be related to an eating disorder, it would be a good idea to seek medical advice.
unwitting adj. 无意的，未察觉的
overeat v. 吃得过多
hormone n. 激素
metabolic adj. 新陈代谢的
cardiovascular adj. 心血管的
Part III. KEY
Q1. B.【解析】细节题。根据“It takes around 20 minutes from when we start eating for the brain to register that we’ve had enough.”，可知从我们开始吃东西到大脑意识到我们已经吃饱，大约需要20分钟。正确答案为B。
Q2. C.【解析】细节题。根据“In one small study, people who ate the same meal in 24 minutes instead of six said they felt fuller with lower levels of the hunger hormone ghrelin found in their blood. And, they ate about 100 fewer calories’ worth of snacks three hours later.”，可知研究发现，那些在24分钟内而不是6分钟内吃完同样食物的人，他们饱腹感更强，饥饿激素水平更低。此外，他们在三小时后摄入的零食热量也更少。正确答案为C。
Q3. D.【解析】推理题。根据“Studies have also linked fast eating with higher rates of belly fat, blood pressure, and metabolic problems like type 2 diabetes.”，可知快速进食与更高的腹部脂肪率、高血压以及2型糖尿病等代谢问题是相关联的。也就是说，快速进食可能会增加代谢谢类疾病风险，因此正确答案为D。
Q4. C.【解析】细节题。根据“Nutritionists have some tips, like using smaller spoons, consciously chewing more, and taking a sip of water in between mouthfuls.”，可知营养学家提供了一些建议，比如使用较小的勺子，有意识地多咀嚼，以及在每口之间喝一口水。正确答案为C。
Q5. A.【解析】主旨题。根据全文，文章主要讨论了吃东西的速度如何影响健康，讲解快速进食可能导致的健康问题以及如何通过慢速进食改善健康。因此正确答案为A。
