A so as B as that C such that D such as 为什么选D
答
很高兴能为你解答疑惑.
答案：D
首先排除B,用法根本不存在,错误显而易见.
这里出现固定用法：so……as/that（如此……以至于） such……as/that（这类/这种……）
区别为：so后面加形容词,举例：so different as/that
such后面加名词,举例：such problem as/that
而such……as与that的区别又有：as引导定语从句,that引导结果状语从句.
such……as引导定语从句,而后面从句中缺主语,属于定语从句,故而选D
希望我的回答能够帮助到你,有任何疑问请继续追问.
