问题 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.Which of the following statements is true according to the article？A.A large amount of antioxidant supplements are not necessary.B.Oxidation can not do anything good at all to our body.C.Plants surviving hard conditions can produce a lot of antioxidant.D.Antioxidant supplements can improve one’s physical performance.
选项 A.A large amount of antioxidant supplements are not necessary.
B.Oxidation can not do anything good at all to our body.
C.Plants surviving hard conditions can produce a lot of antioxidant.
D.Antioxidant supplements can improve one’s physical performance.
答案 A
解析 本题考查的是细节理解。
【关键词】statements；true
【主题句】第1自然段We don’t need massive doses of antioxidants，we need stress to compel our own bodies to create antioxidants.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。
第2自然段“Everybody thinks oxidation is bad，and that antioxidants are good，”says Dr.Jones，“That’s bogus. A little bit of poison is good.”“每个人都认为氧化是坏的，抗氧化剂是好的，”琼斯博士说，“这是假的。有一点点毒是好的。”
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。
第4自然段 These“antifeedants，”when ingested by humans，trigger the body to release proteins and activate genes“produce antioxidants……当人类摄入这些“拒食剂”时，它们会触发身体释放蛋白质并激活产生抗氧化剂的基因……
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.虽然琼斯博士承认维生素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。
【解析】本题的问题是“根据这篇文章，以下哪一项陈述是正确的？” A选项“不必要用大量的抗氧化补充剂”；B选项“氧化对我们的身体没有任何裨益”；C选项“在艰苦条件下存活的植物可以产生大量的抗氧化剂”；D选项“抗氧化补充剂可以改善一个人的身体表现”。根据主题句，琼斯博士否定了“氧化是坏的”观念，故B选项错误；植物是通过激活人体产生抗氧化剂基因，而非自身产生，故C选项错误；琼斯博士认为无法改善身体表现，与事实不符，故D选项错误，因此A选项符合题意。
