关于tony大牛总结贴的一个疑问

看了关于tony大牛的总结贴，有一个疑问

七.逻辑主语。

1.这个考点只需要注意一个问题，什么时候去思考是否有逻辑主语的问题？

标志性结构：a.doing, svo.

b.prep +doing/done, svo

c.adj, svo

d, conjunction +doing/done, svo.

e,doing/done放在主从句之间，一定错！（主义是主从句，不是主谓之间。这个考点一定会被拍砖，非常欢迎大家拍，好好拍，一定要弄清楚那道一年了没有结论的题）逻辑主语是最重要亦是最有效的考点，一定要注意！

可是我看到下面的问题

43.  (26724-!-item-!-188;#058&003285)

 Although ice particles in the upper atmosphere benefit Earth in that they reflect and absorb solar radiation, acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate the destruction of the ozone layer by reacting with chlorofluorocarbons (CFC's).

(A) acting as a global thermostat and thus keeping Earth from either burning up or freezing over, they also accelerate(A)

(B) acting as a global thermostat and thus keeping Earth either from burning up or freezing over, while also accelerating

(C) act as a global thermostat and thus keep Earth from either burning up or freezing over, while also accelerating

(D) they act as a global thermostat that thus keeps Earth either from burning up or freezing over, even though it also accelerates

(E) they act as a global thermostat to thus keep Earth from either burning up or freezing over, but they also accelerate
            

 

解释说A中acting只能向前修饰，不存在歧义，因为如果要向后修饰，必须在Although从句和acting之间加上连词，因为这都是修饰主句的状语，没有连词无法并列存在。
            

 

麻烦各位帮我确认一下，谢谢啦

恩~是的，可能那时候ets还没有出类似的题所以tony没有总结到吧。
