37、ntinue studying human brains, well know more _10_ the science of riskseeking.本文是一篇说明文。文章讲述了人们喜欢冒险的原因和科学依据。1greater解析：考查形容词比较级。这里用great的比较级与句中的better相呼应。2was_passed解析：考查动词的时态和语态。主语“the quality of risktaking”是谓语动词动作pass的承受者，需用被动语态；这里是描述过去发生的事，用一般过去时。3why解析：考查名词性从句。本空后的内容解释了为什么不是所有的人都喜欢冒险，故用why引导宾语从句。4
38、killed解析：考查非谓语动词。过去分词killed作宾语补足语，宾语one与宾补动作kill之间是动宾关系。5that/which解析：考查定语从句。关系代词that/which指代先行词“a range of character types”，引导定语从句，并在从句中作主语。6or解析：考查连词。前后两个分句在意义上是选择关系，故用or连接。7willingness解析：考查词性转换。空格中所填单词前有形容词性物主代词your，且在句中作主语，故用willing的名词形式。8To_help解析：考查非谓语动词。“To help you do that”是不定式短语作目的状语。9taking解析：考查非谓语动词。mean doing sth.意思是“意味着做某事”。10about解析：考查介词。know about sth.是习惯搭配，意思是“了解，知道”。
