争议题GWD25-Q24再开帖，希望nn可以给个定论，A or B

lemonsong

说一下我的看法
我做题的时候选的是 A，看讨论分析之后觉得 B 越来越像正确的
毫无疑问，A 的语法表达是完美的，但 B 的语法也没有硬伤。而且，ETS 的考试逻辑为王，而 B 的逻辑表达远胜于 A，所以不能排除 B 是正确答案的可能。
先说说 A 的逻辑，提高的效率通过增加供应和降低售价会刺激需求，所以推动消费。
1、效率会刺激需求，这个逻辑很有问题；而且 刺激需求——》所以推动消费，中间好像也缺少了必要的说明
2、效率不能作为“增加供应和降价”的逻辑主语，它们的逻辑主语应该是人。
3、boosting 的用法这里是作伴随状语。但对一个表将来的动作（stimulate）伴随感觉不太对，我觉得表结果的伴随状语一般都用在已发生的动作中，而未见过用在对将来的推测中。（这点未经证实，向NN求证）
反观 B 的逻辑表达则合理很多：虽然提高的效率会……，但需求会因为增加供应和降价被刺激，而增加供应和降价会推动消费。
只要 which 引导的非限定定从可以修饰 increasing supply and lowering prices，B 的语法是无大问题的。
希望有NN现身说明一下 noun1 and noun2, which（定从） 的语法点是否被 ETS 认可
只要上述语法点没错， B 会是比 A 更优选的答案

Although improved efficiencyin converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boostingconsumption.
A的逻辑是效率提高-->供应增加价格降低--->需求增加--->消费增加
注意it和efficiency位置相对，指代很清晰哦，而且by引导的部分说明supply和prices才是efficiency和demand的这中间一环哦。
另外逗号加ing放在句尾是修饰整句的，所以导致boost的是整个前边的动作。


Although improved efficiency in converting harvested trees into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boostconsumption.
B中which只能修饰前面挨着的名词，所以B就成了供应增加价格降低导致消费增加。虽然也没有错，但肯定是A中的需求增加导致消费增加更合逻辑。
而且B中第一节讲efficiency，第二节直接跳到demand，根本没提efficiency，却还用了although在哪里，明显run-on

一开始选的是A，后来感觉B有道理，理由如下：

A和B中的increasing以及lowerng不一样
A中的increasing和lowering是接在by后面，也就是说
improved efficiency will stimulate demand by increasing supply and lowering prices.
关键点是：效率不能做增加供应的逻辑主语，增加供应的逻辑主语应该是人。

而B中increasing是作为supply的形容词修饰supply，because of虽然不是很通顺，但是后面接的是名词supply和prices，结构上没错。

至于B中的which，个人认为没有错
先行词是increasing supply和lowering price
不断提高中的供应以及不断降低的价格   会  促进 消费。

PREP 2012 的题。。。别争了。。选A

夏日之浅浅

increasing supply and lowering prices是不是improved efficiency stimulate的？it指代哪个？选了B，现在觉得AB都对呢

A没有错啊……AB之间纠结了好久……

多谢~终于有了定论

A更好，因为although表示转折，前后的主语理应是一个。

B中which的指代可能造成误解，到底是increasing supply 还是 lowering prices，或者是前面的一句话都有问题，而且increasing supply本来就有些问题，increased supply更好些。

Verb form; Grammatical construction; Idiom
The correct version of the sentence must clarify the sequence of two effects of improved efficiency in converting harvested trees into wood products: first, stimulating demand and second boosting consumption. The first of these effects is itself caused byincreasing supply and lowering prices.
A. Correct. The subject of the independent clause it clearly restates the subject of the dependent clause efficiency, and the use of active voice in both clauses clarifies the although relationship announced at the beginning of the sentence.
B. The passive voice in the independent clause obscures the sentence's meaning, making the cause of increasing supply and lowering prices unclear; the relationship between efficiency and demand is similarly unclear.
C. The preposition of is not idiomatic in the context of this sentence; the referent of the relative pronoun which is ambiguous.
D. The passive phrase of harvested trees being converted is wordy and unclear.
E. This sentence obscures the identity of the efficiency that may reduce harvest rates; the passive construction in the independent clause causes further ambiguity. (What will stimulate demand? How are increasing supply and lowering prices causally connected to demand?)
The correct answer is A.
