标题: prep2-43,伴随状语
Although iceparticles in the upper atmosphere benefit Earth in that they reflect and absorbsolar radiation, acting as a global thermostat and thus keeping Earth fromeither burning up or freezing over, they also accelerate the destruction ofthe ozone layer by reacting with chlorofluorocarbons (CFC's).

(A) acting as aglobal thermostat and thus keeping Earth from either burning up or freezingover, they also accelerate
(B) acting as aglobal thermostat and thus keeping Earth either from burning up or freezingover, while also accelerating
(C) act as aglobal thermostat and thus keep Earth from either burning up or freezing over,while also accelerating
(D) they act asa global thermostat that thus keeps Earth either from burning up or freezingover, even though it also accelerates
(E) they act asa global thermostat to thus keep Earth from either burning up or freezing over,but they also accelerate

题目选a，但是我上来就把a排除了。。因为这个acting不也有做后置定语修饰radiation的歧义吗？

这个就是区分后置定语和伴随状语的区别了~

后置定语和伴随好像就是逗号和意思的区别~

现在分词做后置定语的时候是present participle without commas
Eg: the cat sleeping on the rug is named "Sue"

现在分词做伴随状语的时候一般有逗号隔开，同时含义上讲：
1. 表示主句对后面的影响，即 express the result/purpose of the main clause
2. 表示和主句同时发生的动作

谢谢这位同学，不过逗号隔开的做后置定语也很多啊，og和prep都有很多这类的例子噢
比如prep1-113
In the pastseveral years, astronomers have detected more than 80 massive planets, mostof them as large or larger than Jupiter, which circle other stars.

(A) most of themas large or larger than Jupiter, which circle
(B) most of themas large or larger than Jupiter and circling
(C) most of themat least as large as Jupiter, circling
(D) mostly atleast as large as Jupiter, which circle
(E) mostly aslarge or larger than Jupiter, circling

选c, circling 就是做后置定语啊～

小小看法，嘿嘿
一般在GMAt里面，考doing结构和which之间，是看这个结构的逻辑主语到底是什么
逻辑思维
*ING结构的逻辑主语指主句主语，而不是宾语
* SVO, doing 结构，doing修饰主语或整句，doing修饰宾语不要逗号
Which 五个用法

*逗号或介词后。

* 就近修饰逗号前面的名词，逗号后which还是很好的选择
* Which/it不能指代前面整件事

*宾语后which不指主语，不能仅仅记忆为“就近修饰”

*介词＋which优选

以上摘抄一个XDF老师对OG12的讲解，希望有给你解题有帮助

谢谢这位同学，但是，
SVO, doing 结构，doing修饰主语或整句，doing修饰宾语不要逗号
上面的题目里circling就是做J的修饰呀，J就是宾语呀，
prep解释的是circling就是做的J的修饰。。。
