what和which修饰名词做定语的区别

Answer 1

　　区别what,which的小技巧 　
　　一、后接名词时的区别
　　当用作定语修饰其后接名词时，只用which和what。
　　which和what的区别是：
　　前者用于选择范围较小或较明确的场合，后者用于选择范围较大或不明确的场合。
　　如：Which color do you like, black or white?
　　黑色和白色，你喜欢哪种？
　　Which is bigger, the sun or the earth?
　　太阳和地球哪个大?
　　What color is your car?
　　你的汽车是什么颜色的？
　　但是，若指人，即使选择的范围不明确，也可用which。
　　如：Which [What] writers do you like?你喜欢哪些作家? 　　
　　二、what,which其后不接名词时的区别
　　当其后不接名词时，二者均可用，which和what的用法区别依然是：
　　前者用于选择范围较小或较明确的场合，后者用于选择范围较大或不明确的场合。
　　如：Which is in the box, the red one or the black one?
　　哪一个在盒子里，是红色的那个还是黑色的那一个？
　　What is in the box? 盒子里装的是什么东西？
