He arrived in the afternoon, when nobody was home.
This is the town where I was born.
I visited Paris, where I spent a wonderful week.
请问老师,when的先行词是arrived吗?二三句中,where的先行词分别是 the town和visited吗?
第二句中where的先行词是the town。第三句中where的先行词是Paris。
第一句中判断先行词是什么,首先要理解句子的语义。这个when从句是补充说明下午到达时的情况,即到达的时候家里没有人。而不是说整个下午家里都没有人。所以这个when实际上等于at which time,其先行词为谓语部分,即arrived in the afternoon。
补充一个韦氏高阶词典的例句,其中when从句的先行词也是主句的谓语部分:We're still waiting for the test results, when we'll decide our next move.
