题目：counterfeit can be regarded as _____.

文章：the new policy government has nominated to deal with the increasing counterfeit can be regarded as ineffective.

这道题乍一看很简单，答案为ineffective，但是如果你选了该答案的话就落入陷阱了。正确答案应该是increasing。

而这里的陷阱就是黄老师今天要讲的定语从句了。所谓定语从句，就是在一个名词后面加一个从句来修饰该名词，比如the book which you gave that mad person is interesting. 里面的which you gave that mad person就是修饰the book的定语从句。

但是，同学们可能还记得，定语从句在某些条件下是可以省略关系代词which that who的，比如上面那句话，就可以写成：the book you gave that mad person is interesting.

那么，假设现在有一道题：that person is ____. 同学们一定发现了，这道题答案应该是mad，而不是interesting。因为interesting属于主句修饰主语book的成分。

同理，我们再回到上面那道题，同学们可以对比下这两句话：

the book you gave that mad person is interesting.

the new policy government has nominated to deal with the increasing counterfeit can be regarded as ineffective.

大家一定也发现了，虽然第二句话的词明显复杂了一点，但是其实本质上这两句话结构是一样的，都是省略关系代词的定语从句，而第二句话的ineffective其实是修饰主语policy的，所以答案为increasing。
