[求助]大全885SECTION1-17

17.   During the nineteenth century Emily Eden and Fanny Parks journeyed throughout India, sketching and keeping journals forming the basis of news reports about the princely states where they had visited.

(A) forming the basis of news reports about the princely states where they had

(B) that were forming the basis of news reports about the princely states

(C) to form the basis of news reports about the princely states which they have

(D) which had formed the basis of news reports about the princely states where they had（E）

(E) that formed the basis of news reports about the princely states they

A,E比较疑问如下：

1，个人认为forming 和that formed 均可；

2，定语从句先行词states后面跟where,和that的不同？

3；A中定语从句的过去完成时态存在问题吗？

我觉得that指代的是sketching（详细描述） and keeping journals（保留日志） ，所以用that会好点吧

在og中，关于过去完成时是这样描述的， the past perfect properly describes action that is completed prior to some other event described with the simple past tense

所以我觉得在后面这个main clause 中，还是用过去是比较好吧。他们描述和记录，和他们到这个地方应该是同时发生的，没有先后时间关系
