你知道下课的时间吗？（定语从句）It was already five oclock when the class was over.=When the class was over, it was already five oclock. 当下课时己经是5点了。（时间状语从句）When, where和why在引导定语从句时可以用“介词which”的结构来替换，在引导状语从句时却不行。This is the factory in which (where) his father once worked. 这就是他的父亲曾经工作过的那个工厂。（定语从句）Put back the book where it was. 把书放回原处。（状语从句）定语从句中的关系词在从句中充当某种句子成分，因此去掉它则从句成分不完整；而结果状语从句中的连接词在从句中不作任何成分，去掉后从句的成分仍然完整。It is such an interesting book as we all like. 它是我们大家都喜欢的如此有趣的书。（as用作动词like的宾语，它引导的是定语从句）It is such an interesting book that we all like it. 它是一本如此有趣的书，我们大家都喜欢它。（that不充当句子成分，故它引导的是结果状语从句）定语从句与同位语从句定语从句在复合句中相当于形容词，对先行词起修饰、描述或限制的作用，与先行词之间有从属关系。同位语的作用相当于名词，对前面的名词给予补充说明或进一步解释，是前面名词的具体内容,与先行词之间是同位关系。The news that she had passed the exam made her parents very happy. 她考试及格的消息使她父母亲很高兴。（同位语从句）此句中的同位语从句 The news that she had passed the exam 可以改写成表语从句：The news is that he passed the exam. The news that he told us interested all of us.他告诉我们的消息使大家都感兴趣。（定语从句）The news that he told us 是定语从句，此句不能改写为：The news is that he toldus.定语从句与强调句强调句的结构为“It iswas被强调部分that从句”。被强调部分可以是除谓语以外的任何成分，当被强调部分是人时，还可用who代替that。这一句型中，一定不能因为被强调部分是表时间或地点的词就用when或where代替 that。It is on the morning of May 1st _ I met Liang Wei at the airport It is the factory _ Mr Wang works从结构上看：小题是强调句，故填 that。小题则是定语从句，用上述方法转换便知the factory前差个介词in，故填 where。定语从句练习一 在下列定语从句中，用适当的介词填空。1. The pencil _ which he wrote was broken.2. He built a telescope _ which he could study the skies.3. The woman, _ whom I learned the news, is a nurse.4.
