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.Why is stress good according to Dr.Jones？
A：It is good for muscle cramps.
B：It is good for macular degeneration.
C：It goes well with trauma.
D：It makes human body stronger.

本题考查的是细节理解。 【关键词】why；stress；good；Dr.Jones 【主题句】第3自然段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.这种毒性实际上可能来自植物，特别是那些在恶劣条件下存活的植物。在恶劣条件下生存的食物，通过给我们的身体施压使我们更强壮，而不是因为它们富含抗氧化剂。 倒数第2自然段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. 虽然琼斯博士承认了维生素E对肌肉痉挛和黄斑变性的益处，但他并不赞同它可以改善一个人的身体表现。他认为，足球等激烈接触性运动的运动员可以从创伤中受益。“球员必须在周二和周四被垫子碰撞才能在周日比赛 ——他们需要实际的创伤。”他说。 【解析】本题的问题是“根据Dr.Jones，为什么压力是好的？”A选项“它对肌肉痉挛有好处”；B选项“它对黄斑变性有益”；C选项“与创伤相配”；D选项“它使人体更强壮”。根据主题句，是维生素E对肌肉痉挛和黄斑变性有益处，故A、B选项错误；C选项文章未提及，故错误；通过施压，可以使身体更加强壮，故D选项正确。
