33、其他用户的体验。tips 三层级解细节推理判断题细节推理判断题，即要求考生根据文章的某个句子、段落或全文所提供的事实进行逻辑推理，推断出作者没有提到的或者没有明说的事实或者可能发生的情况，旨在考查考生透过词语的字面意义去理解作者言外之意的能力。细节推理判断题题干中通常含有infer, suggest, imply, conclude, intend等标志性词语。此类题型可采用“信息定位同义替换综合分析”法来解答：1跳读，找到相关信息点(即能够进行推理的依据)；2细读，理解相关信息点的字面意义；3分析推理，在理解字面意义的基础上进行符合逻辑的推断，理解作者的言外之意。切勿拿文章中非关键的细节内容作为推理的结论；结合选项，找到与文章信息点所表达意思相近的选项。例如上文第11题属于细节推理判断题，由倒数第二段中的“Online reviews are one of the first things I look at when I am about to buy a new product.”可推知答案，切忌单纯根据字面意思而误选。如B选项中的reviews一词与信息句中的online reviews一致，因此很容易选错。
