D从语法上, in ... growth, so both damaged and slowed can only modify growth
But E, in damaging and slowing the growth of forests...., in + damaging and slowing ...., 语法上, damaging 不必须refer to growth, 而逻辑上, 显然damaging forests更合适
以下是引用shijinnan在2005-3-18 3:30:00的发言: 我对b and e还是有疑惑。我觉得,b 显示这个damage or slow of grow of forests的后果已经造成了。现在没有达成共识酸雨是不是原因之一。而e选项是,作为一个general case来讨论,到底酸雨对雨林又没有破坏的可能。不知道我理解的对否,请大家指正。
b strenthen a situation,a result
but e strenthen a process
since a (the original meaning) strenthen the process,d distort the orinial meaning
