Question

【題目】根據短文內容的理解，選擇正確答案。 Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases (維生素缺乏癥) to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation (營養(yǎng)補充) — and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves.
Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster.
Promoters of vitamins and minerals — especially vitamins A, C, and E— would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you're covered. It's okay to eat fast foods for the rest of the day or skip meals to achieve today's fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber (纖維) and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek.
And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes (胡蘿卜素) from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods.
You'd be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you'd pay much more than if you got the same nutritional value from natural sources.
But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many different supplements as desired. The reported benefits of high dosages of certain nutrients have led some people to believe that the more the better. Many take several vitamin and mineral supplements without regard to possible consequences.
Surprising new research suggests that vitamin C pills may speed up hardening of the arteries, the underlying cause of heart attacks. Researchers said their findings support the recommendations of health organizations, which urge people to avoid high doses of supplements and to get their nutrients from food instead.
As appealing as they're made to sound, nutritional supplements are danger in disguise. If you're looking for good health, don't look on the supplement shelves of your supermarket. Look in the produce section instead.

Answer 1

【答案】
（1）D
（2）A
（3）B
（4）C
【解析】本文介紹的是過分的依賴營養(yǎng)補充藥對我們的身體健康的不利影響，我們還是要尋找天然營養(yǎng)。
（1） 細節(jié)理解題。根據第三段最后一句The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek.（對維生素和礦物質補充劑的關注可能實際上是在掠奪我們所尋求的全部營養(yǎng)）所以答案是：D
（2） 詞義猜測題。根據第三段的內容, 再根據常識可知, 這些營養(yǎng)補充應該是由生意人提供的, 所以答案是：A
（3） 細節(jié)理解題。根據第三段中A diet rich in fiber (纖維) and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement.可知, 你從營養(yǎng)補充劑中不能得到纖維。所以答案是：B
（4） 推理判斷題。根據最后一段第二句If you're looking for good health, don't look on the supplement shelves of your supermarket.（如果你尋求健康的身體, 別看你超市貨架上的營養(yǎng)補充藥。）可知, 這些東西對你的身體是有害的。所以答案是：C
