　　【答案】

　　26. [E] challenges

　　27. [J] searched

　　28. [D] categorizing

　　29. [K] similarities

　　30. [L] slightly

　　31. [G] percentage

　　32. [O] traditional

　　33. [ I ] regardless

　　34. [H] proving

　　35. [M] suggests

　　【解析】

　　26. 根据简单句的基本句型尝试，此空格处应填入谓语动词，再根据时态和主谓一致原则，此处可填入的备选项为challenges和suggests或tastes，再根据前后文语境锁定答案为challenges，这里的challenge是动词，表“怀疑”。

　　27. 根据主谓宾的常识以及时态要求将答案缩小在searched和applied之间，再看空格后面的搭配为for, search for 意思为寻找符合语境;倘若选applied，apply for的意思是申请，与与语境明显不符合。综上，故答案为searched。

　　28. 根据介词后面需要搭配名词或动名词的原则，确认该空格应在名词性质的备选项中记性选择，在根据前后文语义应该填入 categorizing， categorize A as B or C，把A分为B或C;categorize brains as “male”or“female” ，把电脑分为男性或女性。

　　29. 根据句法知识和词性搭配，该空格应该填入名词词性，再根据空格前的逻辑词while表对比这一用法，确定while从句与主句是对比关系，主句中有difference一词，故将答案锁定为 similarities。

　　30. 根据词性搭配原则，此处应该填入副词故而在slightly和briefly之间进行选择，再根据语义将答案确定为slightly。

　　31. 根据词性搭配和small一词的用法，将答案锁定为percentage，a small percentage of 表示一小部分。

　　32. 根据词性搭配尝试此处应该填入形容词，再根据前文语义将答案确定为traditional。

　　33. 此题主要考察单词的固定搭配，regardless of 表示无论，无论从语法还是语义均符合要求，故而选regardless。

　　34. 根据原文，此处从语法方面考虑需要填一个非谓语动词，再根据前文语义故而选择 providing.

　　35. 根据简单句基本句型和时态及主谓一致此处应该填第三人称的动词，再根据语义，只有suggests符合。
