【答案解析】本题考查连词辨析。given做为介词使用,意为“考虑到……”;provided (that)或providing (that)可以用做从属连词,引导条件状语从句,意为“如果……的话”,“只要……”;convince意为“使相信,说服”,常用于句型convince sb. of sth.和convince sb.+that从句; believe为动词,意思为“相信”,“认为”,后面直接跟宾语,很少用过去分词的形式作状语。本题选择C项,convince放在句首,表示“相信……”后面接that从句,从句后为完整的主句时,常用convinced。
【答案解析】本题考查定语从句。根据空白处所在的句子结构,这里需要填入一个引导定语从句的关联词。选项A的however和选项C的what不能引导定语从句,可以排除。选项B的where虽然可以引导定语从句,但其先行词应当是表示地点的词语,故也可以排除。因而本题的正确选项为D。关系代词that引导的定语从句本身是一个复合句,that指代先行词material,research has shown为插入语。
