3.重点句型定语从句：Asasix-year-oldCanadianschoolboy,RyanhadtroublebelievingthewordsspokenbyhisteacherthatmanypeopleindevelopingAfricancountriescouldn’tgetenoughcleanwater.

解析：spokenbyhisteacher是过去分词短语作后置定语，修饰thewords；that引导同位语从句，解释说明thewords的具体内容。

宾语从句：Hewastoldthatitactuallycost$2,000tobuildawell.

解析：that引导宾语从句，作told的宾语；it是形式主语，真正的主语是tobuildawell。

非限制性定语从句：Afterseveralmonths,Ryanhadraisedthe$2,000,withwhichawellwasbuiltnearaprimaryschoolinUganda.

解析：withwhich引导非限制性定语从句，which指代前面的the$2,000，相当于withthe$2,000。
