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.

我选的是B，

C时态不对。

应该是，TV costs accounted a greater proportion in 1992 than (they did) in any previous election

they 指代 TV costs

如果ＴＨＥＹ指代ＴＶ　ＣＯＳＴＳ，那就更应该选Ｂ了吧．．．

应该选B.

a greater than后面应该是一个从句表达以往电视广告费用在总统选举费用中的比例，这个从句有3种选择：

1）完全写完整：than the television costs accounted for... in any previous election.

2) 简化主语谓语：than they did in any previous election.

3) 省略主谓只留下状语：than in any previous election.

3)应该是最简洁的最好的方式。

C选项是想采用2)的省略方式，但是时态不对，而且accounted for是实意动词，应该用do,did等来省略，have been是系统词，不能用来省略实意动词。
