好像没有人进行过成文的总结,我找到一道og的解释,你可以看看 It is a special feature of cell aggregation in the developing nervous system that in most regions of the brain the cells not only adhere to one another and also adopt some preferential orientation. (A) to one another and also adopt (B) one to the other, and also they adopt (C) one to the other, but also adopting (D) to one another but also adopt(D) (E) to each other, also adopting Choice A and B are incorrect because and should be but to conform to the idiomatic construction not only but also. Choice B can be faulted for including they where there should be only adopt to form a parallel with adhere. Moreover, the other in B is inappropriate because many more than two brain cells are being discussed. Choice C contains the other and has adopting in place of adopt, the verb form parallel to adhere. Choice D is correct. In choice E, adopting is again wrong and each other is less appropriate than one another for referring to a multitude of cells. This is a very easy question. |
