不是RUN-ON的问题 GOOGLE出来外国人的解释是 D和E没有语法上的错误 所以我们应该将两者再做别的方面的比较 也就是意思差别的比较了 D and E both correctly start with "an event that caused" - yes, that's both the original intent of the sentence and it's grammatically correct. D introduces another "and" towards the end, which again dictates parallelism (which is not present here) and again mars the original intent of the sentence - one event led to the next, rather than two events being side-by-side parallel E correctly indicates that the event caused the extinctions and those extinctions mark the end of the era -- by 会员 free_over (2010/3/1 15:40:55)
关于D的解释没看得太懂,好像是说, and it marks又引出一个平行概念,但是文中并没有这一层意思,是多余的。 |
