問題詳情：

Anyone caring about their health will be able to speak out a few of the major vitamins,  and possibly take an educated guess at what they do. Vitamin C, found in oranges and other fruit and vegetables, is important for wound repair. And the much-talked-about “sunshine” vitamin D, produced by the skin in response to UV light, is essential for strong bones.

But what about vitamin P? It might well have you scratching your head. And that's not surprising: the term was first coined in the 1930s to describe a small group of compounds that provide pigment(天然*素) to plants, and were believed to have health benefits. A century later, these compounds are now better known as flavonoids(類黃*).

Today, scientists have identified between 4,000 and 6,000 different kinds and we now know they are responsible for many of the flavors and smells of fruit and vegetables and also that they protect them from invaders such as pests and bacteria.

They are equally important nutrients for the body, helping maintain bones and teeth, and for the production of the protein collagen(膠原), which provides structure to blood vessels, muscles and skin.

They are also said to help the body deal with some of the key drivers of illness, including oxidation(氧化), a natural process by which the body's cells age and can become damaged and defective. That means they could help to protect against chronic diseases including cancer and heart disease.

do we know about vitamin P?

would scratch our head if we took it.        refers to the compounds also called flavonoids.

was made into a coin in the 1930s.              le didn't think it beneficial in the past.

h is NOT the function of vitamin P for humans according to the passage?

ing maintain bones and teeth.

sting in producing protein collagen.

lerating the circulation of the blood.

ng the body to handle the main factors of illness.

h of the following best explains “defective” underlined in the last paragraph?

ful.                  ouraged.             e.                     cient.

does vitamin P help slow the aging process?

fighting against oxidation.                        maintaining bones.

strengthening muscles.                             protecting against chronic diseases.

【回答】

1.B; 2.C; 3.D; 4.A 解析：1.細節理解題。根據第二段中的“these compounds are now better known as flavonoids(類黃*)”可知B選項正確。“It might well have you scratching your head” 意為“它很有可能會讓你撓頭(冥思苦想)”,故A選項錯誤;“the term was first coined in the 1930s”意為“這個術語是20世紀30年代被創造的”,故C選項錯誤。根據“were believed to have health benefits”可知D選項錯誤。 2.推理判斷題。根據文章後兩段的介紹可知,維生素P對人體的作用有三種:(1) helping maintain bones and teeth(有助於維持骨和牙齒):(2)… important… for the production of the protein collagen(膠原)(有助於產生膠原蛋白);(3)help the body deal with some of the key drivers of illness(幫助身體應對一些導致疾病的主要驅動因素),因此A、B、D選項是對的,而C選項“Accelerating the circulation of the blood” 説法不對,原文應該是 “The protein collagen(膠原) provides structure to blood vessels, muscles and skin.” 3.詞義猜測題。根據最後一段 “They are also said to help the body deal with some of the key drivers of illness, including oxidation(氧化), a natural process by which the body's cells age and can become damaged and defective.”我們知道氧化會使我們的細胞衰老,受損或變得有缺陷。 4.細節理解題。根據最後一段中的“They are also said to help the body deal with some of the key drivers of illness, including oxidation(氧化), a natural process by which the body's cells age and can become damaged and defective.”可知,維生素P可幫助抗氧化。氧化是人體細胞老化的自然過程,會導致細胞受損和有缺陷,與題幹中的slow the aging process呼應。
