prep 1 - 81

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

答案是A，我选了E，原因是E用了homes had electricity和前半句的public places had installed...对称。其次，后面用了过去完成时，对应at the end of 19th century.

但我承认E中的where不好。请问这是E唯一的错误吗？

另外，请问A的结构为什么好呢？谢谢拉

马上就要考试了，急盼NN答复，谢谢

之所以用过去完成时，是因为前半句有at the end of the nineteenth century，而且全半句也用了过去完成时，我觉得这个应该不是问题啊。我同意where这里指代有问题，但是，应该不存在歧义啊，因为句子里面只有where只可能refer to homes。

请再讨论

where不是普通的错误，是很，非常，及其严重的错误。参见og-38

Scientists have observed large concentrations of

heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.

(A)
                        Baltic Sea sediments, which are consistent with the growth of industrial activity there

(B)
                        Baltic Sea sediments, where the growth of industrial activity is consistent with these findings

(C)
                        Baltic Sea sediments, findings consistent with its growth of industrial activity

(D)
                        sediments from the Baltic Sea, findings consistent
                with the growth of industrial activity in the
                area

(E)  sediments from the Baltic Sea, consistent with the
                growth of industrial activity there

All of the choices but D contain ambiguities. In A and B the words which and where appear to refer to sediments, and in E it is not clear what consistent describes. In A, C, and E, there is no logical place to which there or its could refer. In D, the best choice, the phrase sediments from the Baltic Sea tells where the sediments originate, findings
            provides a noun for consistent to modify, and in the area clearly identifies where the industrial activity is growing.
