Although improved efficiency in converting harvested trees into wood products

may reduce harvest rates, it will stimulate demand by increasing supply and

lowering prices, thereby boosting consumption.

A.     in converting harvested trees into wood products may reduce harvest

 rates, it will stimulate demand by increasing supply and lowering prices,

thereby boosting.

B.     In converting harvested trees into wood products may reduce harvest

rates, demand will be stimulated because of increasing supply and

lowering prices, which boost.

C.    Of converting harvested trees into wood products may reduce harvest

rates, it will stimulate demand by increasing supply and lowering prices,

which boosts.

D.    Of harvested trees being converted into wood products may reduce

harvest rates, it will stimulate demand, because it will increase supply

and lower prices, thereby boosting.

E.     When harvested trees are converted into wood products may reduce

harvest rates, demand will be stimulated because of increasing supply

and lowering prices, which boost.

答案给的是B 偶觉得那个,WHICH肯定有问题~不是PRICES来BOOST CONSUMPTION的

而BOOST应该做一个伴随结果状语,是demand will be stimulated because of increasing supply and

lowering prices,所产生的影响的结果

偶选A

lowering prices,所产生的影响的结果

偶选A

Me too. A

A

楼主的图片倒是挺漂亮,不过这题选A应该是肯定不行的.因为很明显,5个选项中的主句主语分别是由"it"和"demand"构成.如果用"it",那"it"就必须得在逻辑上可以完成此句想要表达的意思.此时和"demand"在逻辑上进行对比,似乎并没有明显的依据说efficiency足已发出主句中的"stimulate"的动作,同时,也更没有依据认为efficiency足已做出increase 和 lower这两个动作(注意:原文的it will do ...by doing ..and doing..).而楼主做为判断依据的"which / doing"之间的区别反而可以找到用"which"的依据,因为之前是A and B的名词平行,所以which boost完全可以用A and B做主语,这里同"DOING"之间的比较并没有什么绝对的逻辑错误.

综上所述,选B没有异议.

对刚才的回复表示抱歉~~~~仔细读了一下,发现本题中所有的动词确实均由efficiency发出.而B中的demand will be stimulated because of .....确实是极度awkward的用法.

对楼主表示歉意~~
