not only...but also...的疑惑，大权354

354 In
                    1978 a national study found that not only had many contractors licensed by a self-policing private guild failed to pass qualifying exams, they in addition falsified their references.

(A) they in addition falsified their references

(B) they had their references falsified in addition

(C) but they had also falsified their references

(D) they had also falsified their references（C）

(E) but their references were falsified as well

请问为什么（c）是正确的？看下面OG-125题中的（c）选项，形式与此题类似，解释说不平行，为何这里又是正确的？

125.
                    The winds that howl across the Great Plains not only blow away valuable topsoil, thereby reducing the potential crop yield of a tract of land, and also damage or destroy young plants.

(A) and also damage or destroy

(B) as well as damaging or destroying

(C) but they also cause damage or destroy

(D) but also damage or destroy（D）

(E) but also causing damage or destroying

Choice D, the best answer, correctly employs the correlative construction not only x but also y, where x and y are grammatically parallel and where both x and y (damage and destroy) apply to young plants. Choices A, (not only... and also), B (not only... as well as), and C (not only... but they also) violate the not only... but also paradigm.  Moreover, B contains terms (blow... damaging) that are not parallel. In C and E, damage is used not as a verb with young plants as its direct object but as a noun receiving the action of cause; consequently, these choices fail to state explicitly that the damage is done to young plants. E also violates parallelism (not only blow... but also causing).

一个优先问题，选项中没有完美的not only...but also...时，可以退而求其次。但是如果选项中有完美平行的，就一定要选完全平行的那个。GMAT的正确选项并不是最完美的选项，而只是较好的那个。

记得有个牛人讲过,第一个是倒装,倒装的结构后面的but also要插入代词以平行,不加不好

但是没有倒装的时候不能插入代词,加入是错
