现在分词局尾表伴随的疑问

现在总结些东西,有两个疑问,请牛牛确定.

1. differentiate from / differentiate between A and B 的区别:

用法上有区别,前者通常为 A differentiate from B, 指 A区别于B; 而后者通常为某人differentiate between A and B.

2. 关于现在分词局尾表伴随的疑问, 如下例:

I walk my dog that usually walk with me after dinner, eating some snack.

这里现在分词应跟主句动作伴随还是跟从句?还是象某些大虾经常所指示的根据具体句意判断?

1. In my opinion, "distinguish / differentiate A from B" is almost equal to "distinguish / differentiate between A and B." isn't is? Different uses are based on different contexts, I guess.

2. I think "还是象某些大虾经常所指示的根据具体句意判断" is correct. well, it might be confused sometimes.

Two good questions!

One more phrase for the 1st question, what's the difference between discriminate A from B and discriminate between A and B.

Waiting for the explanations!

我想问问这句I walk my dog that usually walk with me after dinner, eating some snack.你是从哪儿看来的？

最好能把原句找出来。我认为1. 从意思判断：主句+that+从句，doing sth.中doing意思可能只跟其中之一有逻辑关系，另一个明显不对。2. 如果如你所举的这句，我认为在gmat中可能是错误选项，因为它造成了歧义，应该避免这种情况的发生。

我在做princeton的时候碰到过类似的题目，我记得一个选项that从句, doing就是错的。具体的记不清了。

OG120. The Parthenon was a church from 1204 until 1456, when Athens was taken by General Mohammed the Conqueror, the Turkish sultan, who established a mosque in the building and used the Acropolis as a fortress.
(A) who established a mosque in the building and used the Acropolis as
(B) who, establishing a mosque in the building, used the Acropolis like
(C) who, when he had established a mosque in the building, used the Acropolis like
(D) who had established a mosque in the building, using the Acropolis to be
(E) establishing a mosque in the building and using the Acropolis as

这里选项E的错误是:and in E, establishing and using modify Athens, thus producing an absurd statement.感觉ETS认为现在分词句末就是修饰主句的,而不是根据具体意思来定.是不是有现在分词和定语从句的选项. 1. 简单句选现在分词,因为简洁.2. 如果是复杂句,现在分词容易造成歧义的,就避免,而用从句.???

你所说“ETS认为现在分词句末就是修饰主句”，此时的主句是The Parthenon was a church from 1204 until 1456，所以establishing a mosque in the building and using the Acropolis 没有修饰主句，还是从句Athens was taken by General Mohammed the Conqueror，只不过此时用了被动，establishing and using感觉像是修饰Athens，而实际应该是General Mohammed the Conqueror。如果此句用了主动，我认为establishing and using也是可接受的。

继续求教:

如果答案里有现在分词和定语从句的选项,如上面的例子如您所说用了主动,那么该选哪个?

是否 1. 简单句选现在分词,因为简洁.

       2. 如果是复杂句,现在分词容易造成歧义的,就避免,而用从句.???
