(1)考查时态语态。句意：最近，中国科学家在河南省南阳发现了很多种恐龙骨头。由“recently”可知，本句的时态为现在完成时，主语Many kinds of dinosaurs' bones和动词find之间是被动关系，所以用被动语态，故填have been found。
(2)考查连词。句意：当科学家们检查这些骨头时，他们惊讶地发现这些恐龙不仅能像其他恐龙一样奔跑，而且还能爬树。分析句子可知，此处缺少从属连词引导时间状语从句，故填When。
(3)考查非谓语动词。be surprised to do sth.惊讶地做某事，故填to spot。
(4)考查介词。like作介词意为“像”，根据句意可知，此处应填like。
(5)考查副词。句意：恐龙在大约6千万年前突然灭绝。die out固定短语，“灭绝”故填out。
(6)考查代词。think 后接省略that的宾语从句，宾语从句中缺少主语，主语指的是恐龙灭绝这件事，用it来指代，故填it。
(7)考查形容词。unexpected意外的，应用形容词修饰名词incident，故填unexpected。
(8)考查连词。when引导的时间状语从句中缺少连词来连接hit和put，hit与put为并列关系，故填and。
(9)考查固定短语。not any more固定短语，“不再”。本句的否定词隐含在前文的too...to… (太……而不能) 中，故填more。
(10)考查介词。句意：没人确切地知道恐龙为什么在这么短的时间内从地球上消失以及是如何消失的。for sure固定短语，“确切地”，故填for。
[点评]本题考点涉及时态语态，连词，非谓语动词，介词，副词，代词，形容词等多个知识点的考查，是一篇科普类阅读，要求考生在理解细节信息的基础上，进一步根据上下文的逻辑关系，并结合相关语法知识，进行分析推理，从而写出正确的单词形式。
