which非限制性定语从句作文好句?

一、基本结构与用法

补充说明作用

which引导的非限制性定语从句用于对先行词或整个句子进行补充说明，去掉后不影响主句意义。例如：

*This project, which was completed last year, has won several awards.*

指代内容

可以指代物（如：*the book which I found*）或整个主句（如：*which surprised everyone*）

二、典型应用场景

描述事物特征

*The company, which operates in three countries, is one of the largest in the industry.*

时间/地点状语

*Where the meeting was held, we discussed the project's next steps.*

三、写作建议

位置要求：

必须用逗号与主句隔开，且位于先行词后

避免混淆：若先行词被形容词最高级修饰（如 *the tallest building*），需用that引导限制性定语从句

替代关系：可替换部分从句结构，如将 *which arrived just now* 替换为 *that arrived just now*（需注意that仅限限制性定语从句）

四、扩展句型

*which + 动词 + 宾语 + 定语*：*which was published last month has been widely read.*

注：使用which时需注意与that的区别，后者仅限限制性定语从句。建议结合具体语境选择合适引导词，并通过替换练习提升写作能力。
