解析
【分析】
本题包含语法填空和词汇拓展两部分。语法填空需结合固定搭配、时态、词性变化、连词用法等基础语法知识点解题；词汇拓展考查单词的词性与词义。具体思路：26题依据固定搭配和冠词用法；27题根据过去时间状语确定时态；28题由语境判断介词；29题用否定句并列连词；30题按hundreds of的用法；31题结合定语从句时态；32题用比较级修饰规则；33题选特殊疑问词；34题用动名词作主语；35题用形容词性物主代词；36、37题根据词汇知识判断词性和词义。
【解析】
26. 考查冠词与固定搭配。search for是固定短语，表“寻找”；此处泛指“一个尘土飞扬的区域”，dusty以辅音音素开头，故填a。
27. 考查一般过去时。句中时间状语One morning表过去，描述过去动作用一般过去时，故填noticed。
28. 考查介词。此处表“用小工具”，介词with可表“使用（工具）”，故填with。
29. 考查连词。否定句中连接并列成分用or，构成“not...or...”表“不是……而是……”，故填or。
30. 考查名词复数。hundreds of后接可数名词复数，piece的复数是pieces，故填pieces。
31. 考查一般过去时。定语从句描述过去营地的动作，用一般过去时，故填played。
32. 考查形容词比较级。much修饰形容词比较级，great的比较级是greater，故填greater。
33. 考查疑问词。特殊疑问句询问“什么秘密”，用疑问词What，故填What。
34. 考查非谓语动词。此处作主语，用动名词，Study的动名词是Studying，故填Studying。
35. 考查形容词性物主代词。修饰名词find用形容词性物主代词，they的对应形式是Their，故填Their。
36. 考查单词词性与词义。gene是名词，意为“基因”，故填n. 基因。
37. 考查单词词性与词义。guardian是名词，意为“守护者”，故填n. 守护者。
【答案】26. a 27. noticed 28. with 29. or 30. pieces 31. played 32. greater 33. What 34. Studying 35. Their 36. n. 基因 37. n. 守护者
