“173.The widely accepted big-bang theory holds that the universe began in an explosive instant 10 to 20 billion years ago and has been expanding ever since.e

A.that the universe began in an explosive instant 10 to 20 billion years ago and has been expanding

B.that the universe had begun in an explosive instant 10 to 20 billion years ago and had been expanding

C.that the beginning of the universe was an explosive instant 10 to 20 billion years ago that has expanded

D.the beginning of the universe to have been an explosive instant 10 to 20 billion years ago that is expanding(A)

E.the universe to have begun in an explosive instant 10 to 20 billion years ago and has been expanding

错误选项E. had been expanding与holds并列错误，begin逻辑上应该与expand并列；hold…to have begun的表达不如宾语从句直接”



错误选项E. had been expanding与holds并列错误，begin逻辑上应该与expand并列；hold…to have begun的表达不如宾语从句直接”



笔记对E选项的分析不够清楚
1. 个人认为E选项错误在于，holds这里表示holds一个观点，holds something to do 是逻辑错误；E选项作为一个完整的从句看, begin和expand的并列不存在问题。

笔记里面的解释有待商榷，请斑竹指正,大家讨论。

2. E选项用的是have,而非had，希望版本更新的时候能修正一下，以免confuse同学们。
