Q31:

When a ton of wheat was being moved from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and cost $100, but when the canal was used, it took less than eight days and cost less than $6.

 

  1. When a ton of wheat was being moved from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and cost $100, but when the canal was used, it
  2. Moving a ton of wheat from Buffalo to New York City before the opening of the Erie Canal in 1825, it took three weeks and cost $100; using the canal, it
  3. Before the opening of the Erie Canal in 1825, moving a ton of wheat from Buffalo to New York City took three weeks and cost $100; on the canal the move
  4. In 1825, before opening the Erie Canal, to move a ton of wheat took three weeks from Buffalo to New York City, which cost $100; moving it on the canal
  5. To move a ton of wheat in 1825 from Buffalo to New York City took three weeks before the opening of the Erie Canal, costing $100, but in using the canal, the move

答案是C，可是我觉得选A

A里面when..., it...,but when...it....看起来很好的，C 就不平行了

请NN帮助解释一下吧，谢谢！

A is wrong.       what is "it"??   "it" in A could be either "the openning"  or  "a ton of wheat".

哦，有道理。

今天做了很多大全的题，发现很多地方只要it出现就有点指代不明。

呵呵，谢谢解释！

in A, "was being moved"進行時感覺也不大好。

it took sb sometime to do sth, "it" refers to nothing. it is right, anyway.
