标题: OG13 97题 求大神们讲解下 没看过这个知识点
Some anthropologists believe that the genetic homogeneity evident in the world’s people is the result of a “population bottleneck”-at some time in the past our ancestors suffered an event, greatly reducing their numbers and thus our genetic variation.
A. at some time in the past our ancestors suffered an event, greatly reducing their numbers
B. that at some time in the past our ancestors suffered an event that greatly reduced their numbers
C. that some time in the past our ancestors suffered an event so that their numbers were greatly reduced,
D. some time in the past our ancestors suffered an event from which their numbers were greatly reduced
E. some time in the past, that our ancestors suffered an event so as to reduce their numbers greatly,
我看到有帖子的解释如下:破折号的确是解释的意思,但是并不妨碍平行。
破折号后面解释的是前面的整个 "Some anthropologists believe that the genetic homogeneity evident in the world’s people is the result of a ‘population bottleneck"。作用是用更通俗易懂的语言来表达前面整句话。
Anthropologists believe X - (they believe) Y.
X = that the genetic...
Y = that at some time...
我的问题是破折号后面不能是简单的解释吗为什么一定要平行?

没有一定要平行,你可以在OG里面找到破折号不平行的用法。

只是说破折号不一定都平行,没说believe后面接从句的话,不加that啊。我要暴躁了!
