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. A. a greater proportion than it was B. a greater proportion than C. a greater proportion than they have been D. which is greater than was so E. which is greater than it has been
A. It这里不能指代一句话,指代错误; B. 正确;原句补充完整:Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than the proportion television costs had accounted for the spending in any previous election; C. they have been中的been与之前的accounted不对应,直接改成were就好;they指代错误;指代同B中还原后的正确句子;现在完成时使用错误,in any previous election说明应用过去完成时; D. Which不能指代前面的词语; E. Which不能指代前面的词语;it指代不清。
后面的讲解我总觉得有问题,望大神讲解一下?in any previous election说明应用过去完成时?
