Q24

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.

答案是d，我选a，请诸位探讨！感谢！

a: Although ....., it will [stimulate demand] by [IS] and [LP], thereby [bossting consumption].

d: Although ....., it will [stimulate demand], because [IS]+[LP], thereby [boosting comsumption].

逻辑上来说，D选项清楚一些。stimulate demand的原因是boosting comsumption，而IS和LP是boosting comsumption的前因。

用括号表示分句间相互关系：although ...., [it will SD, because (IS and LP, thereby BC)]。

至于efficiency of，其中心词不是单纯的harvested trees，而是一个sth. been done的分词结构（类似于独立主格结构，表示完整的主语和动作）。

虽然efficiency in doing sth.是常用的词组和表达方式，但事实上，本题使用此结构是有待商榷的——毕竟这里doing没有主词。
