资料：What，if anything，do we gain by clinging to our antioxidant supplements？

Very little，according to an accumulating body of research. We don’t need massive doses of antioxidants，we need stress to compel our own bodies to create antioxidants.“Everybody thinks oxidation is bad，and that antioxidants are good，”says Dr.Jones，“That’s bogus. A little bit of poison is good.”

That poison can actually come from plants，especially those that have survived harsh conditions. Foods that have survived harsh conditions make us stronger by stressing our bodies，not because they’re rich in antioxidants.

As the science quarterly Nautilus explains，plants have developed an arsenal of chemicals to help them ward off insects and grazers. These“antifeedants，”when ingested by humans，trigger the body to release proteins and activate genes that “produce antioxidants，enzymes to metabolize toxins，proteins to flush out heavy metals，and factors that enhance tumor suppression.”

Plants prepare your body to handle toxins in the same way as exercise prepares you to race-by stressing your body. And supplements，says Dr.Hooper，interrupt this process.

“These antioxidant supplements are like a Trojan horse，”continues Dr.Hooper. They say，I’m a good guy. You guys go to sleep and while the defense is asleep the antioxidants get rid of any oxidation. It puts the defense-system’s army to sleep.

While Dr.Jones acknowledges the benefits of vitamin E for muscle cramps and macular degeneration，he doesn’t approve the idea that it improves one’s physical performance. He suggests that athletes in intense contact sports such as soccer and football benefit from trauma. “Players have to be hit with pads on Tuesdays and Thursdays in order to compete on Sundays-they need that actual trauma.”he says.

“Everything in our society is geared toward，How can we reduce stress？”adds Dr.Hooper. “When it should be just the opposite. We need stress. Stress is good.

What is the purpose of this article？

A.to correct the misunderstanding of antioxidant supplement
B.to encourage readers to taken more vitamine
C.to encourage readers to do more physical exercise
D.to inform athletes of the benefits of trauma

本题解析：

本题考查的是主旨大意。

【关键词】purpose

【主题句】第1自然段What，if anything，do we gain by clinging to our antioxidant supplements？如果有的话，我们通过坚持使用抗氧化补充剂获得了什么呢？

第2自然段Very little，according to an accumulating body of research. We don’t need massive doses of antioxidants，we need stress to compel our own bodies to create antioxidants. 根据一项积累的调查研究显示，通过抗氧化补充剂收获寥寥。我们不需要大剂量的抗氧化剂，我们需要压力来促使我们自己的身体产生抗氧化剂。

【解析】本题的问题是“这篇文章的目的是什么？”A选项“纠正对抗氧化补充剂的误解”；B选项“鼓励读者多服用维生素E”；C选项“鼓励读者多做体育锻炼”；D选项“告知运动员创伤的好处”。根据文章，作者主要是通过引用两位博士的研究，论证使用抗氧化补充剂是不必要的，纠正人们对其的误解，故A选项正确。
