第1题:

Nutritionists are quick to point out that supplements can be harmful, and that most people who eat a balanced diet have no need for them. What’s more, whole foods contain a host of other substances that seem to help vitamins and minerals be absorbed into the body and to do their job inside cells. Vitamins do not provide balance to a poorly selected diet, but while it is best to change unhealthy behaviors, getting selected nutrients in the form of supplement is better than not getting them at all. The type of supplement that is least likely to be harmful is a multivitamin, one that contains a combination of different vitamins and minerals. Ingredients in multivitamins are generally present at a lower dose than in specific formulas. So it is harder for them to be over consumed and cause damage.

题目问的是“营养学家对补充剂有什么看法”。文章说到：Nutritionists are quick to point out that supplements can be harmful, and that most people who eat a balanced diet have no need for them.（营养学家很快指出，补充剂可能有害，而且大多数饮食均衡的人不需要它们。），说明营养学家认为补充剂可能有害。因此B选项“They can be harmful.（它们可能有害。）”正确。

第2题:

题目问的是“在存在不健康行为的情况下，文章建议做什么”。文章说到：while it is best to change unhealthy behaviors, getting selected nutrients in the formal of supplement is better than not getting them at all.（虽然最好改变不健康的行为，但以补充剂的形式摄取所需营养总比完全得不到要好。），说明在无法立即改善不健康行为的情况下，服用多种维生素补充剂比完全不摄取营养要好。因此C选项“Taking supplements is better than none.（服用补充剂总比什么都不做要好。）”正确。

第3题:

题目问的是“为什么多种维生素补充剂最不容易有害”。文章说到：Ingredients in multivitamins are generally present at a lower dose than in specific formulas. So it is harder for them to be over consumed and cause damage.（多种维生素中的成分通常比特定配方中的剂量低。因此不容易过量摄入而造成伤害。），说明多种维生素最不容易有害的原因是它们的营养成分剂量较低。因此C选项“Lower doses reduce overdose risks.（较低剂量可降低用药过量的风险。）”正确。
