Discoveringusefulstructures;Learninggoals;revision;2.什么是定语从句？

在复合句中，修饰一个名词或代词的从句叫做定语从句。

Iknowthegirl.Thegirlisinred.(两个简单句)

→Iknowthegirlwhoisinred.（定语从句）

被修饰的词是thegirl。这个词就称为先行词。

其中连接两个句子的是that，称为关系词。关系词在从句中指代先行词，并在从句中充当一定的成分，;;revision;更详细地描述人和物;1．(教材P4)Therecomesatime______theoldmustgivewaytothenew,anditisnotpossibletopreserveeverythingfromourpastaswemovetowardsthefuture．
