Question

I bought a storybook yesterday ____ cover is white.这个题的空里要写whose，为什么？

Answer 1

定语从句特点：1）先行词在从句中做成分，可为主语，宾语，表语，定语，状语。
2） 引导词代替先行词在从句中做相应的成分，引导词的判断根据先此词所作成分判定
3） whose 做引导词引导定语从句的特点是先行词在从句中做定语，也可以理解为，先行词和从句中的名词间存在所属关系。
He is the student whose father got a big fish.(the student's father)
We all like the book whose writer is HanHan (the writer of the book)
注意：在非限定性定语从句当中，whose= the + 名词 + of + which
He bought a golden watch, whose hands was made by gold.
He bought a golden watch, the hands of which was made by gold.
