問題詳情
Reading ComprehensionHow do you react to the taste of different foods, like coffee or lemon? Do they have a flavor that you like? Or do they taste very strongto you? Why do people react differently to different flavors?We all know that different people have different food preferences. Researchers have discovered some reasons for these differences.Your culture and your life experience are partly responsible for your preference for certain foods. Your food preferences are also partlygenetic. (Your genetic preferences are the ones that you were born with.) In order to discover people’s genetic preferences, researchers usea chemical called PROP. People taste it and respond to the taste. To some people, PROP has no flavor. The researchers classify these peopleas “nontasters.” To other people, the flavor of PROP is a little bitter, or sharp. These people are “tasters.” Then there are people who can’tstand the flavor of PROP. They find it to be unbearably bitter. These people are the “supertasters.” Tasters have more taste buds on theirtongues than nontasters do, and supertasters have more taste buds than tasters do. This explains why supertasters are more sensitive toPROP and to the flavors in certain foods. So if you think the flavors in coffee, grapefruit juice, and broccoli are very strong, you may be a“supertaster.”

你如何對不同的食物，如咖啡或檸檬的味道做出反應？他們有味道你喜歡嗎？還是他們對你的味道很強？為什麼人們對不同口味有不同的反應？我們都知道不同的人有不同的食物喜好。研究人員發現了這些差異的一些原因。您的文化和您的生活經驗部分負責您對某些食物的偏好。你的食物偏好也是部分遺傳的。 （您的遺傳偏好是您出生的偏好。）為了發現人們的遺傳偏好，研究人員使用一種稱為PROP的化學物質。人們品嚐它並回應品味。對某些人來說，PROP沒有味道。研究人員將這些人分類為“非人員”。對其他人來說，PROP的味道有點苦澀。這些人是“品嚐師”，那麼有人不能忍受PROP的味道。他們覺得這是難以忍受的苦澀。這些人就是“超級大師”，品嚐師比他們的口舌更有口味，超級大師比品酒師有更多的味蕾。這就解釋了為什麼Supertaster對PROP和某些食物的味道更敏感。所以如果你認為咖啡，葡萄柚汁和西蘭花的味道很強，你可能是一個“超級大師”。

回2F從文中" In order to discover people’s genetic preferences, researchers use a chemical called PROP. "中可明確知道PROP只是研究的工具，目的仍是為了研究出基因的影響。
