分析 本文主要讲述了指纹的唯一性及它在刑事案件侦破中的重要作用.
解答 36--40 GCDFA
36.G 考查上下文理解判断能力.根据下文Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children可知,科学家和专家都证明了指纹的独特性,父母没有遗传给小孩相似的纹路排列,那前文应提到了指纹的唯一性.故选G.
37.C 考查上下文理解判断能力.根据前文Burns,cuts and other damage to the outer part of the skin will be replaced in time by new one,which bears a reproduction of the original pattern及下文Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take可知,烫伤和刀伤等不会改变指纹,而罪犯销毁指纹也是危险的.即表层皮肤受损不能改变指纹,只有深层皮肤受损才可改变.故选C.
38.D 考查上下文理解判断能力.根据下文Because of the simplicity and economy of this system,finger-prints have often been used as a method of solving criminal case可知,指纹鉴定已经被使用来作为解决刑事案件的一种方法,前文应是:使用特殊的方法,身份确认可以在短时间内成功地达成.故选D.
39.F 考查上下文理解判断能力.根据前文A suspected man may deny a charge but this may be in vain可知,嫌疑犯否认指控是徒劳的,即年龄,面貌或其它特征的改变,指纹也不会改变.故选F.
40.A 考查上下文理解判断能力.根据前文When a suspect leaves finger-prints behind at the scene of a crime,they are difficult to detect with the naked eye可知,嫌疑犯留下的指纹很难用肉眼看到,那下文应是:特殊的技术使之现形.故选A.
点评 七选五题型看似简单,实际上有时完全作对并不容易,需要方法和分析能力及足够的耐力,有必要进行专门练习.首先,快速浏览一遍七个备选答案,先确定哪个选项适合放在文章的什么位置.其次,快速浏览文章,确定文章体裁,抓住文章结构,分析篇章结构,找出各段的主题句或主旨大意.其三,注意各选项中出现的句子衔接手段,寻找句中衔接标志词,七选五备选答案中有两个多余的选项,会对文章中两个空的选择构成干扰,这时要特别细致地比对相似选项.最后,用代入法,检查答案是否合理,将所有选择答案放回空白处,通读全文,检查文章内容是否语义连贯合理、紧扣主题,语篇结构是否通顺连贯、具有一致性、合乎逻辑,写作思路是否清晰明了,格式以及用语是否恰当贴切,从而判断选择的答案是否正确.
