1.There is no consensus on what role, if any, is played by acid rain in slowing the growth or damaging forests in the eastern United States. (A) slowing the growth or damaging (B) the damage or the slowing of the growth of (C) the damage to or the slowness of the growth of (D) damaged or slowed growth of (E) damaging or slowing the growth of 答案是E,但是和C相比,虽然C用了名词,但是E可能会有歧义,可能是damaging or slowing the growth of (forests)破坏森林和减慢森林的增长,也可能是damaging or slowing (the growth of forests)破坏和减慢森林的增长。所以我最后选了C更加清晰的情况。为什么呢?
