supported 15 ． whether 16 ． has
【导语】这是一篇说明文。介绍的是人们更喜欢一些味道而不是其它的味道的一个原因，是因为人们对气味的偏好是习得的，这个理论也是越来越多地被专家支持的。
14 ．考查非谓语动词。句意：被专家越来越多地支持的一个理论表明气味的偏好是习得的。分析句子结构可知，空格处的动词做非谓语，结合空格后的 by experts 可判断出该处意为 “ 被专家们支持 ” ，所以空格处应用过去分词表被动。故填 supported 。
15 ．考查宾语从句的引导词。句意：解释我们怎样确定气味是不是危险的是容易的：我们学习到的。分析句子结构可知，空格前的 determine 为及物动词，空格后是主 + 系 + 表的句子结构，所以空格处的词用来引导宾语从句。再结合句意及空格后句子中的 or not 可知，此处考查 whether…or not 的搭配。故填 whether 。
16 ．考查主谓一致。句意：气体本来没有可识别的味道。分析句子结构可知空格处的动词作谓语，本句话是在陈述客观事实，应用一般现在时态，且主语 gas 在本文中指的是气体的统称，为不可数名词，所以谓语动词要用单三形式。故填 has 。
