解析

【分析】
首先通读整篇短文,明确文章核心讲述的是科学家在沙漠区域发掘恐龙化石的相关研究发现,先梳理题干给出的备选词和对应的变形方向,之后逐空分析句子的语义和语法结构:第一步先判断每个空缺处需要的词性/成分,第二步结合上下文语义匹配对应的备选词,第三步根据语法要求将单词变形为正确形式,最后代入全文通读检查逻辑是否通顺。
【解析】
31. 句意:埋在沙子里的是比普通岩石有趣得多的东西——是一块古老骨骼的部分残骸。前文提到发掘偏远区域,后文也多次提到沙漠、沙子相关内容,此处表示埋藏的地点,直接填入短语in the sand即可。
32. 句意:团队使用特殊的刷子和工具小心地从沙子中揭开化石的秘密,不破坏它。此处考察固定搭配use sth. to do sth. 表示“使用某物做某事”,结合语义“揭开、解锁秘密”,将unlock变为不定式形式to unlock。
33. 句意:研究人员随后讨论这种生物是否在环境完全不同的时期曾生活在这里。此处位于动词discuss之后引导宾语从句,表达“是否”的含义,直接填入引导词whether。
34. 句意:他们的发现表明,非洲的北部区域很久以前可能是湿润葱郁的,不像现在这么干旱。此处需要形容词修饰名词areas,结合备选词northern表示“北部的”,符合语义,填入northern。
35. 句意:当地专家解释,这个非洲的化石可以提供关于这些古老生物如何生存的重要信息。此处需要形容词修饰名词fossil,将名词Africa变为形容词African,表示“非洲的”,符合语境。
36. 句意:这个令人激动的发现帮助科学家更好地理解我们星球的历史。此处形容词exciting后面需要接名词作句子主语,将动词discover变为名词形式discovery,表示“发现”,符合语义。
【答案】
31. in the sand
32. to unlock
33. whether
34. northern
35. African
36. discovery
【知识点】
短文选词填空,词形转换,宾语从句
【点评】
本题属于记叙类语境选词填空题,整体话题贴近自然科学探索,既考查学生对全文主旨和上下文逻辑的理解能力,也考察了固定搭配、词性转换、宾语从句引导词等基础语法点,易错点集中在35、36空的词形变形,学生容易直接填入原形忽略词性修饰要求。
