回複：Thank you for a thorough explaination.

1. Try to avoid slang in your writing, such as "a whole bunch of...." They confuse,annoy and discourage your readers. --I never knew this is a slang

2. Never put a comma before that-induced clauses, such as "that the poet vividly and incisively...". Besides, the clause led by "that" in your sentense doesn't modify "envisagement". haha, i put that comma without realizing why :)

3. More than several cases, I found, in your sentences, the subjects do not agree with predicates,especially in relatively longer sentences. --That's why i hate writing. if possible would you please provide me  more examples? 

4. Tense. Such as this one, "After I wake up, I will only see..."  After waking up?

Ok, enough hammers from me for today.
