请教SC 一道：为啥A不对呀？

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

there by和then一样是副词不是连词吧

A的正确写法应该是.....,and there by boosting....

答案是C么？我觉得哈，boost consumption 应该只是lower price 的功劳吧，而A选项用句末分词反应的是主句主语或者整个句子造成的影响或者结果，逻辑分析下就知道不对了~

关键不是词性的问题

这个问题之前有讨论过很多的，建议楼主可以去这个链接看：

B is better, only the lower prices can boost consumption

sucy

B the best

it 指代有问题，A中指improved efficiency . 根据意思指Harvest Rates更符合情况。

另外，By表示伴随的方式或动作。如果用By的话意思就是增加供应和降低价格和Stimulate Demand同时发生。根据意思，Stimulate demand 应该是Increasing Supply And Lowering Prices的结果。

Boosting放到句末有两种解释情况。1，修饰整个句子表示伴随状况或结果，2，就近修饰名词。
