修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。被定语从句修饰的名词或代词叫先行词。引导定语从句的词叫关系词。关系词有关系代词和关系副词。关系代词有who、whom、which、that、whose、as等。

1.which/that　考查定语从句。分析句子结构可知,此处引导定语从句,修饰先行词a company,关系词在从句中作主语,指物,故填which或that。
2.which　考查非限制性定语从句。分析句子结构可知,逗号后面是非限制性定语从句,关系词指代前面的整个主句内容,且在定语从句中作主语,故填which。
3.whose　考查定语从句。分析句子结构可知,这是一个倒装句,此处为定语从句,先行词an artist与paintings构成所属关系,故填whose。
4.who　考查定语从句引导词。分析句子结构可知,所填词引导定语从句,修饰指人的先行词their masters,且在从句中作主语,故填关系代词who。
5.who∕that　考查定语从句。先行词是westerners(西方人),定语从句中缺少主语,故填关系代词who或that。
