看了很多帖子都没解决我的问题。我理解as 和 like 的区别就是，作比较， A do as B do， A like B.  as 连接的应当是主谓结构，like连接的是两个名词，就像题目中A/B选项和其他三个选项的区别一样。照此推论，句子中 computer reason 应当接 as expert does呀，为什么用 like expert呢？ 我理解只有C的后半句是正确的，难道因为这一点就忽略了like的问题了么，即没有最佳答案就选次优的？还是因为是动宾结构 make computer reason 就可以用like了？

先谢谢了

reason 在修饰computer的that从句里，computer在that 从句外，在句子结构上不和reason属于一层。所以是computer like an expert.

d,e逻辑错，b which 错，a. these错。A,b, as.. does错

那就应当是 make computer .... like an expert 对吧？多谢了
