果介词和Which搭配在一起并不表示以上三种意思，则我们只能保留介词+Which的形式。如 I know English in which I wrote the love letter.
4．判断关系代词与关系副词
方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要
求用关系代词；而不及物动词则要求用关系副词。
判断改错：
（ ） This is the mountain village where I visited last year.
（ ） This is the mountain village which I visited last year.
（ ） I will never forget the days when I spent in the countryside.
（ ） I‘ll never forget the days which I spent in the countryside.
