标题: (请教)OG 18/101

18.   Computers are becoming faster, more powerful, and more reliable, and so too are modems, they are the devices to allow two or more computers to share information over regular telephone lines.

(A) so too are modems, they are the devices to allow

(B) so too are modems, the devices that allow

OG解释“To allow is not an idiomatic way to modify devices; either that allow or allowing would be correct.

请问:为什么不能用to allow 呢?

101.
                    
El Nino, the periodic abnormal warming of the sea surface off Peru, a phenomenon in which changes in the ocean and atmosphere combine allowing the warm water that has accumulated in the western Pacific to flow back to the east.

(D) is a phenomenon in which changes in the ocean and atmosphere combine to allow the warm water that has accumulated

(E) is a phenomenon where ocean and atmosphere changes are combining and allow the warm water accumulating

OG解释:

If the participial phrase were to modify the previous clause, a comma would have to be inserted between combine and allowing. A better choice would be to follow combine with to allow,

C)showing purpose.combine to allow shows the purpose of the changes.

为什么这里又反过来呢?

想不明白。请指教。谢谢。

18,

不定式作后置定语,与前面修饰词有动宾关系,they are the devices to allow two or more computers,意思就变成allow devices,歧义。比如i have something to do ( do sth); i want somthing to eat, 诸如此类;

101,combine 接-ing分词,本身结构就混乱,GMAT中,分词应该修饰近身名词,或逗号隔开修饰句子(前面的动作),或者放在句首,修饰主句主语(我能看到的,就这三种),此句中三者都不符合。换成to do 表结果。

不知道理解的对否

为什么呢?combine不可以是名词吗?LS所说的结构混乱是不是因为加ING没有道理呢?比如不是固定搭配之类的啦?

恩~ 觉得ing分词出现的情况好像也就这三种。got it。

combine如果是名词,就没谓语了

不理解对于to allow的解释,和下面那一题中的用法不同吗?
