问题描述：
When travelling in buses or trains,we are likely to have conversations _____ we give information or opinions about different things.
A.where \x05B.which \x05C.what \x05D.when
答
A.
where = in which = in the conversations.
把这个复合句拆开成两个简单句,你不用关系副词/代词,而用人称代词或重复相同的名词（短语）：
1.When.,we like to have conversations.
2.----we give information or opinions about different things.
告诉我：----we.前面你打算填什么?才能和前句衔接起来?
当然是：In the/ our conversations we give.things.
好了,在用关系代词或关系副词把这两句合并,还原成原句吧!
In the/ our conversations = in which = where
合起来：When...,we like to have conversations where we give.
如果,B,加个 in ,即,in which,当然是可以的.
明白了,给个回答.
