题目选A，可是A的 and has been expanding 前面没有that ，不就是和holds平行了么？theory怎么能expanding？其他的选项也明显不对啊 作者: xiangzhengj 时间: 2010-6-27 22:22
是the universe has been expanding作者: stucashS 时间: 2010-6-28 06:40
If you add "that" before "has been expanding", you parallel two clauses and create a faulty parallelism, "the theory holds that the universe began in an explosive instance" and "[the theory holds]that has been expanding ever" since." Clearly the second clause lacks a subject.作者: stucashS 时间: 2010-6-29 06:43
明白了 谢谢！可是has仍然有跟在theory后面的歧义啊~
