十三、复合句——形容词性(定语)从句
    定语从句的测试重点：选择正确的关系代词或关系副词。
    切记：关系代词/副词一定要在从句中充当某种成分，即主语、宾语、表语或定语。指人时用who(做主语)、whom(做宾语)、whose(做定语)；指物时用which或that；指时间用when；指地点用where；指原因用why。此外还要注意如下几个问题：
   
    1.尤其要注意whose的用法
    whose在从句中做定语，修饰名词。所以，如果关系代词后面紧接的是名词，且关系代词又不在从句中做主语或宾语，那么，这个关系代词就应该是whose。如：
    Of course developing a system for helping students whose needs are out of the ordinary had been a necessary step in helping those students get into the world of public education.
    It is perhaps not an exaggeration to say that we shall soon be trusting our health, wealth and happiness to elements with whose very names the general public are unfamiliar.
