4．The voluminous personal papers of Thomas Alva Edison reveal that his inventions typically sprang to lire not in a flash of inspiration but evolved slowly from previous works．
(A) sprang to life not in a flash of inspiration but evolved slowly
(B) sprang to lire not in a flash of inspiration but were slowly evolved
(C) did not spring to lire in a flash of inspiration but evolved slowly
(D) did not spring to lire in a flash of inspiration but had slowly evolved
(E) did not spring to life in a flash of inspiration but they were slowly evolved
Parallelism +Idiom
The construction not．．．but shows a contrast．The words following not must be parallel in construction to the words following but．In the original sentence not is followed by a prepositional phrase(in a flash of inspiration)；but is followed by a verb(evolved)．To make the two contrasting elements parallel，not should be followed by a verb rather than a phrase．
A Construction following not is not parallel to the construction following but．
B Construction following not is not parallel to the construction following but ,the passive voice were evolved is incorrect．
C Correct．In this sentence，not is followed by the verb spring just as but is followed by the verb evolved．
D Had evolved introduces an incorrect verb tense．
E Construction following no．t is not parallel to the construction following but．
The correct answer is C．
请问用D为什么不对？inventions 复数不是说明这个发明的过程不是瞬间的吗
