there are many things important for sc, which we do not see in general grammar books. that is why we stay here.
to refer to a general action, we should use the noun not doing. of course, if there is no noun, we have to use doing.
the problem is that general action is different from the action caused by an agent/noun in the sentence. we have to realize that "doing" in this case take different gramartical role. "doing' in this case refers to a specific action caused by an agent in the sentence. "doing" in this case is called particile in grammar book but it is never explained fully in those book while, in the test, gmac test us this point.
compare"
learning english, I make my thinking better.
learning (of) english is good.
in the first sentence, learning is caused by "I". in the second sentence, learning refers to a general action. in the sentence, there is no agent which cause "learning".
this thing is not explained in general grammar books but is tested on gmat sc. why gmat test us this point ? because this point affect the meaning of the sentence and so is considered important.
gmat do not test us the rarely used idioms, because it think that most non natives can not use those idioms . gmat want a logical writer, not a grammarian remembering many rarely used idioms.
there is one more point. some times, doing is used to refer to general actions though the relevant noun exists. this situation happens because paralelism should be considered more important than the choice between doing and the noun. an example for this case is the question " spliting apart ..." in og books. pls do searching in the pdf files of og 11 or 12. you will find the problem.
do you agree with me? if you think my posting is helpful. pls say thank
