请牛牛们和版主现身拍砖吧！OG verbal 88的一些自己的看法，觉得OG的解释有点问题。

DesmondWang

Clouds are formed from the evaporation of the oceans’ water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust. A.Clouds are formed from the evaporation of the oceans’ water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
B.Clouds form by the Sun’s warmth evaporating the water in the oceans, which rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
C.Warmed by the Sun, ocean water evaporates, rises high into the atmosphere, and condenses in tiny droplets on minute particles of dust to form clouds.
D.The water in the oceans evaporates, warmed by the Sun, rises high into the atmosphere, and condenses in tiny droplets on minute particles of dust, which forms clouds.
E.Ocean water, warmed by the Sun, evaporates and rises high into the atmosphere, which then condenses in tiny droplets on minute particles of dust to form as clouds.
这道题选C没问题，但这里我对OG对B的解释有点疑问：
“the antecedent for the relative pronoun which is ambigous, again suggesting that oceans rise high”
B.Clouds form by the Sun’s warmth evaporating the water in the oceans, which rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
但是仔细看了一下，which后面是rises，所以我觉得oceans应该不能做rises的发出者，而应该是water做发出者，in the oceans是define "water"的mission critical modifier. 这样的话我觉得which rises high into指的就是water，make sense.
另外看了很多帖子，说condensing的逻辑主语是clouds，我觉得不对啊，以前听Ron说过“，participle” modify the closest tensed verb. 也就是“S.V....that S.V....., -ing...”这里的-ing应该修饰that后面的成分，prep07的43题：
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).划线句就是正确答案。这里acting和keeping的逻辑主语都是they reflect and absorb...

所以回到原题，我觉得B的错误一个在于sun's warmth evaporating the water这个表述非常笨拙，第二个在于这里原文的意思是三个动作的连续，而不是从属关系，所以不能用condensing。但不清楚这么分析对不对，到底应该如何排除B呢？请各位NN们拍砖！不胜感谢！

LZ判断B是错的两个理由有点道理，但对condensing的分析有问题，B选项中condensing的确是作为状语表结果，修饰了主句Clouds form by the Sun’s warmth evaporating the water in the oceans。

这道题主要是三个连续动作的并列，而B选项中，which rises high into the atmosphere是作为非限定定语，condensing in tiny droplets on minute particles of dust做了状语，所以与作者原意是不符的，这是B错误的真正所在。

谢谢，终于有人回复了，你说的三个连续动作我同意的。
但是还是没搞清楚B选项里-ING的修饰对象。我还是要说prep的那道题：
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).
记得ron的讲座（还是他的回复？记不清了），这道题的acting做的是in that后面的reflect和absorb的adverbial modifier，reflect和absorb在although句子的in that后面。
还有一道OG的题
In a plan to stop the erosion of East Coast beaches,the Army Corps of Engineers proposed building parallel to shore a breakwater of rocks that would rise six feet above the waterline and act as a buffer,absorbing the energy of crashing waves and protecting the beaches 这里的absorbing和protecting是做would rise的adverbial modifier，这里的would rise的逻辑主语应该是 breakwater of rocks.而不是the Army Corps
再回到这句话的A和B
A.Clouds are formed from the evaporation of the oceans’ water that is warmed by the Sun and rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
B.Clouds form by the Sun’s warmth evaporating the water in the oceans, which rises high into the atmosphere, condensing in tiny droplets on minute particles of dust.
我觉得这里的condensing也应该是is warmed和rises的adverbial modifier，逻辑主语是water而不是clouds。所以我觉得您所说的用condensing的逻辑主语是clouds来排除，我不是很想得通，难道是钻牛角尖了吗？
请继续拍砖，谢谢！

更简单的来说 我的问题在于此， S1+V1+Objective that/, which (S2)+V2....., -ing....
这里-ing 到底修饰S1+V1还是S2+V2,
thx a lot!

都有可能，你上述的疑惑

我见过ving跳跃插入语修饰前面的句子，作为正确的选项，我记得是prep上面jupiter的一个题目


当然我也见过manhattan的instructor因为ving存在修饰插入语这个clause的歧义而排除了这个ving的选项


这个点真不好讲
