高中定语从句课件PPT(条理清晰)
关系词： 用来引导定语从句，为避免先行词的重复出现用来代替先 行词的词。分关系代词和关系副词。
常见关系词：that, which, who, whom, whose, when, where, why, as
先行词与关系词的联系
• 1）"先行词"与"关系词"的内在联系"先行词"与"关 系词"之间实质上是互等、互换的关系。也就是说， 关系词的作用就是将先行词所表达意义"代到"从 句中来起作用。例如：
二：先行词已有序数词或形容词的最高级或the last, the only等作定语时，例如：
This is the most impressive TV theater that has never been put on show before. 这是以前从未上演过的最有感染力的电视剧。
That is the only way that leads to your success . 那是通向你成功的唯一之路。
Do you know the man whom you just spoke to? 错误：I have no idea about the man whom wrote the article.
• 关系代词whose ：用于代替"表示人或物意义"的 先行词，在从句中作定语，往往与它所修饰的名 词一起构成一个名词短语在从句中担当成分。 Whose常表达"某人的、某物的"之意。例如：
• 2）“先行词”的意义决定“关系词”的选择“关 系词”的选择往往是由“先行词”自身表达的意 义，以及它在从句中的语法功能而决定的。例如：
• Some people who are successful language learners often fail in other fields.
