ding and nervous system problems.
24. It has seen that large doses of multivitamins .
[定位与替换]本题是问从文章中可以看出服用大剂量的多种维生素会怎样?根据题干中的large doses of multivitamins可以定位到文章第七段的第二句,大剂量的服用可能会引起麻烦,例如失血过多或造成神经系统的问题。所以应该选A) may bring about serious side effects可能会引起严重的副作用。side effects是对原文中excessive bleeding and nervous system problems的概括性替换。
[干扰项分析] B) may help prevent excessive bleeding 可能有助于帮助防止失血过多,与原文说法相反;C) the likely to induce the blockage of arteries可能会引起动脉堵塞,文中无信息支持;D) are advisable for those with vitamin deficiencies对于那些维生素缺乏的人是可取的,也无信息支持。
Multivitamins are no substitute for exercise and a balanced diet, of course. As long as you understand that any potential benefit is modest and subject to further refinement, taking a daily multivitamin makes a lot of sense.
25. The author concludes the passage with the advice that _______.
[定位与替换]本题是问作者用一个什么建议来总结全文的?最后一段的意思:当然,多种维生素不能代替锻炼和平衡的饮食。只要对此理解了,就应知道该选D) it’s reasonable to take a rational dose of multivitamins daily每日服用合理的剂量是明智的。
[干扰项分析] A) the benefit of daily multivitamin intake outweighs that of exercise and a balanced diet与文章最后一段的第一句相反;B) it’s risky to take multivitamins without knowing their specific function在不知道维生素具体的功能之前就服用是危险的,这不仅不是作者的建议,而且与原文第六段的说法不一致;C) the potential benefit of multivitamins can never be overestimated维生素的潜在好处永远不可以被高估,这也不是作者的建议。
