444.It is possible that Native Americans originally have migrated to the Western Hemisphere over a bridge of land that once existed between Siberia and Alaska.
(A) have migrated to the Western Hemisphere over a bridge of land that once existed
(B) were migrating to the Western Hemisphere over a bridge of land that existed once
(C) migrated over a bridge of land to the Western Hemisphere that once existed
(D) migrated to the Western Hemisphere over a bridge of land that once existed
(E) were migrating to the Western Hemisphere over a bridge of land existing once

想请教  若不探究句意   C的用法 migrated over a bridge of land to the Western Hemisphere 有错误吗

表面上看是没有多大错误的，但是正规的英文还是要考究一下句子的结构。更贴切地表达才是好的英文。c.d这里的区别主要是后面的定语从句前面的先行词的问题。所以说关键是在这里。

OG说，

existing once in E is imprecise.

什么叫imprecise？？我觉得根本就是错的呀？？？

同问！

且B的existed once是不是错的？？

Choice D, the best answer, correctly uses the past-tense verb forms migrated and existed to refer to actions completed in’ the past. Choices A, B, and E present incorrect verb forms for expressing simple past action, and existing once in E is imprecise. Although choice C manages the correct tense, it misplaces the sentence elements so as to suggest that the Western Hemisphere once existed between Siberia and Alaska.

上面是OG的解释,这里so as to是什么意思?

哪位NN回答一下上面我的问题啊.这段OG解释的so as to是什么意思啊?记得以前说so as to的用法不对啊.

5 so as to do something formal in order to do something:

I drove at a steady 50 mph so as to save fuel.

We went along silently on tiptoe so as not to disturb anyone.

谢谢JOE老弟.那么以前人总结的"so as to不可以用"的说法是错误了?我记得以前有好多人总结过so ... as to/so that的用法时提到过.

是否是修饰歧异啊？A of B ＋existing.... 是否是因为分不清到底是修饰A（a bridge）呢，还是修饰B( land)呢？

请求nn确认。
