求教：prep-2-111（现在分词作伴随）

问一下B中that a star从句中谓语是神马？

同问，
不是一般 ing放在最后的时候会有修饰歧义吗？

例如PREP2 101

101.    (29777-!-item-!-188;#058&004380)

The electronics company has unveiled what it claims to be the world's smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs less than 11 ounces.

(A) to be the world's smallest network digital camcorder, the length of which is that of a handheld computer, and it weighs
(B) to be the smallest network digital camcorder in the world, which is as long as a handheld computer, weighing
(C) is the smallest network digital camcorder in the world, which is as long as a handheld computer, and it weighs
(D) is the world's smallest network digital camcorder, which is as long as a handheld computer and weighs
(E) is the world's smallest network digital camcorder, the length of which is that of a handheld computer, weighing

答案是D, B错的原因就是weighing后置修饰有歧义， 可能修饰camcorder,也可能修饰句子主语company, 如果要修饰从句里的camcorder, 需要用连词连接。

那么 (B) that a star as bright as the full moon exploded into view 340,000 years ago, emitting
这里的emitting 按说也有修饰歧义呀！！！！

首先，我们看LZ的句子。Astronomers have uncovered evidence that a star as bright as the full moon exploded into view 340,000 years ago, emitting... 这里，我们看句子的主语是Astronomers have uncovered evidence。而emitting做为伴随状语修饰a star（那个从句里的主语）

再看你的句子：is the world's smallest network digital camcorder, the length of which is that of a handheld computer, weighing。从逻辑上看weighing是修饰 camcorder 或者computer的。注意，无论是主句里的还是从句里的，这2个全是宾语。


GMAT的语法题里，这种ing表示伴随的，都是由主语发生的动作。 怎么说呢？分词跟着主语走就对了。

也许我说清楚了吧。。大家继续探讨

ing.都是跟宾语这个说法确定吗？好像以前有专门说明

那么楼主的句子没有主语的修饰歧义吗？
