参考答案
【正确答案:C】
【译文】当我试图弄清是什么妨碍美国人开心时,我发现似乎有两个原因。
【解析】()that prevents so many Americans from being as happy as oneexpects表达是underetand的宾语从句,该从句的主语是what,谓语是prevents,意思是“什么阻止了……”;但为了对what进行强调,此处对从句主语what使用了强调句型it is what thatprevents...,考虑到what具有从句引导词的作用,它必须置于从句句首与前面的understand形成对接,于是语序进而调整为wha it is that prevents...,故本题答案选C。
A、B和D代入句中均不能形成语义和结构完整的句子。
【点睛】本题目是强调句型It is...that...对“从句主语(what)”进行强调。
