　　非限制性定语从句

　　The larger of the two islands is Britain, which lies to the east of Ireland. 两个岛屿中较大的一个是不列颠，它位于爱尔兰的东面。Its capital is London, which is also the capital of the UK. 其首府为伦敦，伦敦同时也是联合王国的首都。

　　非限制性定语从句是对所修饰的词作进一步的说明，通常用逗号与先行词分开，并不对它所修饰的先行词起限定作用，而是作进一步补充说明，也就是说在翻译的时候译成两个句子。如：上星期天我丢了手表，还没找到。Last Sunday I lost my watch, which is not found yet.

　　而限定性定语从句则对所修饰的词起限定作用，在句子中至关重要，若去掉了就会造成句子意思模糊。例如：Do you know the man who came to see me this morning ? 你认识今天上午来找我的那个人吗？

　　Yesterday I met Li Ping, who seemed to be very busy. Abraham Lincoln, who led the United States through these years, was shot on April 14, 1865 at a theatre in Washington, D.C. Football, which is a very interesting game, is played all over the world.

　　对比下面两组句子：

　　1. His brother who is a PLA soldier is eighteen years old.

　　His brother, who is a PLA soldier, is eighteen years old.

　　2. All the books there that have pictures in them were written by him.

　　All the books there, which have pictures in them, were written by him.
