Vitamins do not provide balance to a poorly selected diet, (17) but while it is best to change unhealthy behaviors, getting selected nutrients in the formal 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.

题型总结

Section B 中的推理题

题型分析

推理类题目考查学生在弄懂细节信息之后，理解关键语句背后的深层含义。考生要综合各类信息、关键词、上下文和语气语调等要素，做出逻辑分析判断，读懂说话人的真实想法。常见提问句式：What does the man mean/suggest/imply/indicate by saying…? What can be inferred/concluded from the talk? What do we learn from the passage?

解题技巧

推理题本身特征并不明显，所以考生要提前浏览选项。留意选项当中的专有名词，理清各个信息之间的逻辑关系。在理解陈述事实的基础上，进行归纳或是逻辑推理，读懂说话人的隐含含义，判断后续可能出现的情况。日常用语和说话语气同样可以作为答题参考。这一部分听力文本篇幅更长，上下文逻辑更加清晰，题目之间关联性更强，方便考生推理作答。
