翻了几页，说说自己的想法，希望大家在讨论一下。我选错C。原题重贴如下，OA is B.

Q16:

Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than it was in any previous election.

1. a greater proportion than it was
   
   
2. a greater proportion than
   
   
3. a greater proportion than they have been
   
   
4. which is greater than was so
   
   
5. which is greater than it has been
   

"a greater proportion"  是 “more than half”的同位语，这个应该没有问题吧。然后把原句改写：Soaring television costs accounted for （more than half）a greater proportion （of） the spending in the presidential campaign of 1992, than soaring television costs accounted/had accounted for a proportion of the spending in any previous election.



再改写：Soaring television costs accounted for （more than half）a greater proportion （of） the spending in the presidential campaign of 1992, than they did/had done in any previous election.

然后复原成同位语形式: Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than they did/had done in any previous election.

所以A错， 因为1, 如果it用来指代proportion，那么was不对，应该去掉；2，如果it指代TV costs,则明显也不对，应该用they。was不对,应该用were 或者 had been (costs are proportion of ) 或者 应该用did 或者had done （costs accounted for a proportion of），

c错，因为have been事态不对，应该用were 或者 had been (costs are proportion of ) 或者 应该用did 或者had done （costs accounted for a proportion of).b 对，是因为比较前后主谓都一样，可以省略。

鄙人之见，希望牛牛们来指正。

同意，比较的是介宾部分，而A的it was把proportion提成了主语。

感谢，查了三个贴子只有这个说的最明白，我同意啊，时态的问题到这里才弄明白

我还是不明白，为什么it 就不能指代proportion?或was必须要除去？谢谢解答！！！

it 如果指proportion的话  那表明是同一事物 那显然1992的proportion和previous election的proportion不是同一回事
如果有was 的话 那前面应该有相对应的 动词吧  显然前面没有
所以错了

我发现好多题目都涉及这个地方啊，大概比较的时候出现同一类的时候其实要用that 或者those代替吧

另：以上同一个帖子中，楼主对时态的分析也很好。

再发问，是否如果答案是“a greater proportion then it”就可以了？
