In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.


A. electricity was in less than one percent of homes, where lighting was still  


B. electricity was in less than one percent of homes and lighting still  


C. there were less than one percent of homes with electricity, where lighting was still being


D. there was less than one percent of homes that had electricity, having lighting that was still  


E. less than one percent of homes had electricity, where lighting had still been


answer is A

想请问各位nn,为什么说这个had still been的时态不对啊？未划线部分的 had installed electric lighting不也是一样的吗？

感谢感谢！！！！

我的看法：but后跟了一个独立的主句，where引导一个从句修饰but后主句中的home。所以如果where从句中没有明确表示时间的词，那么where从句中的谓语应该和but后主句的谓语动词时态对应，即和“was”对应，而不是和but之前的句子的谓语动词时态对应。如果从句用过去完成时，则表示动作先于主句的was，这明显不是句子要表达的意思。句子所表述的两个情况是发生在同一时间段的。

以供参考

谢谢．

 but　less than one percent of homes had electricity, where lighting had still been．．．．

是和but里面的时态对应的呀？

还是不太明白

我来解释下

首先，E的where 是不对的，它修饰地点，所以，唯一逻辑的就是home

其次，grammtically, past perfect denotes an action completed at a specific time in the past.

作为home,它需要用simple past 来奠定一个时间点，来给theaters, restaurants, shops, and banks 那些做reference (不知道我这个expression是不是很awkward...)

所以，它不能用past perfect

OG 17,80,都是很好的例子，仔细看看ets的解释，一定能体会到的
