求助OG13 几道题目， SC17

torresAing

17 . Sunspots, vortices of gas associated with strong electromagnetic activity, are visible as dark spots on the surface of the Sun but have never been sighted on the Sun’s poles or equator.

(A) are visible as dark spots on the surface of the Sun but have never been sighted on

(B) are visible as dark spots that never have been sighted on the surface of the Sun

(C) appear on the surface of the Sun as dark spots although never sighted at

(D) appear as dark spots on the surface of the Sun, although never having been sighted at

(E) appear as dark spots on the Sun’s surface, which have never been sighted on

OG说B 没有标点符合，On the surface 。。。of the sun是ungrammatical and makes no sense ；
什么意思？？？

on the surface of the Sun和the Sun’s poles or equator紧接着用不是很奇怪麽~所以不合乎文法。。B选项好奇怪啊

stlibai

b选项是插入语,前后要加逗号的.
我原来选了E.现在看是不是因为改变了句子中心所以错啊？

恳请指导

E选项完全扭曲了句意

而且which在GMAT中，都不可以使用非限定性定语从句

感谢ls~我基本所有问题你都有回答,真是又牛又善良

应该是我刚做og的时候不知道要尊重划线句原句犯的错误

同意DUKB24的说法。
非限制性定语从句还是挺常见的。
但是本题中，如果是which引导非限制性定语从句，句子内容就乱了套了。语法可能没问题，但是基本不知所云了。

额......which不是只能非限制性修饰么= =that才是限制性啊 我凌乱了.....
虽然这题是通过逻辑排除E。E选项，我认为此处which错误指代Sun’s surface，不合逻辑。且原句平行并转折的逻辑层次改变了。
