D【句意】完成整个建设需要二百万元【解析】在这里what引导一个主语从句，what既起引导作用，又在从句中作谓语动词need的宾语，如：What I want to know is why energy, unlike matter, is not made up of molecules and atoms. 我想要知道的是，为什么能量不像物质那样是由分子和原子组成的。

因此D是正确选择。

尽管that也可引导主语从句，但不能在主语从句中做成分，所以B和C错误。

关系代词what不能用来引导定语从问，所以A也不正确。

2. C【句意】尽管我们想要帮助她，Sara却拒绝了。

【解析】for在这里意为“虽然，尽管”，相当于in spite of，notwithstanding，如：For all his efforts，he didn't succeed．虽然他尽了力，但还是没有成功。
