定语从句简化的四种方法

定语从句简化的四种方法

定语从句用来修饰名词或代词，为了使句子更简结，可以把定语从句简化为短语，其方法有以下几种：

一， 当定语从句中谓语动词的后面是介词短语时，只需要去掉关系代词和谓语动词即可，例如：

1:The student that is from Canada speaks French.

The student from Canada speaks French.

2:The book that is on the table is expensive. The book on the table is expensive.

二， 当定语从句是主动结构，且是进行时态（现在进行时态和过去进行时态），或者当定语从句表示经常性的动作或状态时，可以简化为分词短语，例如：

1:The boy that is reading a book is Tom.

The boy reading a book is Tom.

2:The students who study here are all from Shanghai.

The students studying here are all from Shanghai. 1

三,当定语从句是被动结构时，去掉关系代词和助动词，成为一个过去分词短语，例如：

1:This is a book which was written by a writer. This is a book written by a writer.

2:The floor that was swept by Bill yesterday is clean now.

The floor swept by Bill yesterday is clean now.

四，当定语从句中的谓语动词，表示一个将要发生的动作或者有某种情态意义时，可以简化为动词不

定式，例如：

1:She has a lot of work that she must do.

She has a lot of work to do. 简化下列定语从句：(作业题)

1:I bought a book that was written by Luxun.

2:That boy who is studying in class is my brother.

3:Now I have one thing that I must tell you .

4:The man that is at the school gate is my headmaster.
