标题: 以前的帖子没说清楚啊 og 196

196. 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

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.

我想问一下og的解释中 existing once in E is imprecise是什么意思啊？？谢谢！！

汗，字面意思啊

E中的existing once 不准确。

不知道LZ是不是问这个啊。

existing once 与that once existed 不是一个意思吗？难道once 放到后面修饰不行吗？

改变副词的位置就会改变它的修饰对象。

同意carolhide, 而且我好像觉得Once的意思都不一样了呢
