定语从句中介词+关系代词的结构一定可以换成关系副词吗?
比如这些句子: (1) We have decided to go on a world tour in which we'll perform in ten different metropolises. (2) The plane in which we flew to Canada is very comfortable. (3) The person with whom you talked is the very man which we're looking for. (4) The mathematic problem about which they are discussing is obviously very complicated. 另外,顺便问一下有没有这样的情况:只能用介词+关系代词引导定语从句,而不能用对应的关系副词引导定语从句?
不一定啊!where,when,why分别表示地点,时间,原因的关系副词.而介词+which的意思可以有很多其他的意思.不是这三种意思的情况下自然是不能替代的.上面4句都是不能替代的.
