Answer 1

分析 本文关于怎样分析信息及信息来源的可靠性，并给出了一些评估健康信息来源的建议：1、找到信息最初的来源；2、注意误导性的语言；3、运用你的常识；4、做出适合自己的决定．

解答 GDFBA
1．G结构分析题．通过整体把握，可以发现文章是"总分总"的结构，第一段与最后一段是开头和总结，而中间的段落便是作者提出的建议．因此第一段末的句子应该起到统领下文各条建议的作用，故选G．
2．D上下文串联题．本段的关键词是the original source信息最初的来源，作者建议要认真考虑研究的内容，并能检测判断这些内容是否科学；D项中的the original research同the original source相对应．故选D．
3．F语境辨析题．根据本段的标题是：Watch for misleading language．注意误导性的语言；再根据Some studies will find that a behavior"contributes to"or is"associated with"an outcome； this does not mean that a certain course must lead to a certain result．可知有些研究发现某些行为与某种结果有关．那么作为读者我们要知道有些信息也许是错误的解释了，所以我们要细心阅读以求充分理解．F项符合语境．故选F．
4．B联系上文题．根据前句Be especially careful of information contained in advertisements．可知要我们特别注意广告里包含的信息，因为广告里的信息是为了向我们出售一些内容，所以广告的信息很可能是不准确的．所以要当心江湖骗术．空格前提到的advertisements和B选项中的an ad是对应的．故选B．
5．A小标题选择．本段说朋友和家人可能也会提供很多的建议和想法，但是我们每个人都应该找到适合自己的，故与选项A表达的意思是相同的，即要做出适合自己的决定．故选A．

点评 对于此类题型的解答，可以将整个文段首先浏览一遍，大概理解意思．答题过程中，根据所提供的答语或是后文进行作答，同时，做题过程中也可以使用排除法，将选项带到文章中逐一的作答，答完后注意通读检查是否符合逻辑，语义顺畅．
