2. such...as...与such...that...的区别 such...as...中的 as 引导的是定语从句， 而such...that...中的that引导的是结果状语从句。 当as 引导定语从句时，as 在从句中一般作主语或宾语 。 而that引导结果状语从句时，that在从句中不作任何成 分，即从句是非常完整的句子。 This is such a difficult problem ______ all of us can’t work out.（从句中的work out缺少宾语，前面的as是关系代 词，用作work out的宾语。） This is such a difficult problem ______ all of us can’t work it out.（从句是完整的句子，前面的that只起引导从句 的作用，在从句中不作成分。）
