Question

In 1975, George Carlin appeared on a popular TV show, Saturday Night Live, with his famous words about blue food. “Why is there no blue food? I can’t find blue food—I can’t find the flavor of blue! I mean yellow is lemon; orange is orange and red is cherry. Where is the blue food? ”

Well, Carlin pretty much has it right—there’s not no blue food, but there’s certainly not a lot of it. Fresh-picked blueberries are blue, though they become purple when they are turned into jam. The blue in blueberries—like the purple in grapes and the red in tomatoes—is found in nature. But it isn’t a hot color for food. People don’t seem to prefer blue food. Some diet programs even suggest that those determined to lose weight should make their food blue.

Eating, in part, begins with our eyes. Charles Spence—an experimental psychologist from Oxford University—points out that color can change our taste experience. Commonly, we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour. Spence suggests: human expectations may be influenced by our long history of watching - green fruits can become sweet as they grow up and turn red.

But what about blue? Except blueberries, much of the blue food we see these days is dyed blue artificially. Food producers argue that artificial color doesn’t do much harm to health. A lot of research shows that some physical problems of kids are related to food dyes—while other studies show no effects at all. Blue birthday cake or even blue-dyed chicken can be served on the dinner table. So what?

【解析】

試題分析：本文是一篇說明文，通過對科學(xué)實(shí)驗(yàn)結(jié)果和人們飲食習(xí)慣的分析，介紹了日常飲食中藍(lán)色食物很少見的原因。

1. 文章結(jié)構(gòu)題。文章首段George Carlin所說“Why is there no blue food?...”是為了引入文章主題，即：為什么生活中藍(lán)色食物很少見。故該題正確選項(xiàng)是D。

2.“Fresh-picked blueberries are blue, though they become purple when they are turned into jam.”可知選項(xiàng)A錯誤。根據(jù)“The blue in blueberries—like the purple in grapes and the red in tomatoes—is found in nature.”可知選項(xiàng)B錯誤。選項(xiàng)D的內(nèi)容文中并未提及，故該題正確選項(xiàng)是C。

3.“we consider red-colored foods up to 20% sweeter than they actually are; and green foods as being more sour.”可知，選項(xiàng)B錯誤。選項(xiàng)C是對“not hot”的錯誤理解，因此是錯的。根據(jù)“human expectations may be influenced by our long history of watching”是指人類的飲食經(jīng)歷受長時間觀察食物生長經(jīng)驗(yàn)的影響，而不是說吃東西之前要觀察很久，因此選項(xiàng)D錯誤。根據(jù)“that color can change our taste experience”，可知該題正確選項(xiàng)是A。

4.“green fruits can become sweet as they grow up and turn red.”和后面“But what about blue? Except blueberries, much of the blue food we encounter these days is dyed blue artificially.”可知，前文說食物生長過程中改變顏色，轉(zhuǎn)折詞“But”表示轉(zhuǎn)折，“artificially”意為“人工地”，可知“is dyed”意為“被染色”，故該題正確選項(xiàng)是C。
