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.

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

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

首先theory后面最好用that，排除D和E。

C太复杂，有begin动词尽量不用名词

B的过去完成时态有错误！

所以答案选A。

请大家讨论一下这样解释是否合理？

不是theory后面应该用that吧~
这里是宾语从句啊~
其他应该这么考虑吧,

这是宾语从句所以用that, 大多数情况下解释theory都是后面跟that+从句

begin一般用begin doing或begin to do

C和D中，还有个错是用beginning做从句的小主语了，与后面的expand搭配不合适，所以排除C，D
