问题:不太明白从句that在这里是修饰哪个的,该怎么理解,给出的答案是a我选了e

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.

我觉得应该选a呀,给出的答案是b,which去修饰price,不太明白,我认为是前面那句话导致了boost的啊,

a应该更好吧,而且b换成了被动...大家讨论讨论

Q29.

The army cutworm moth is a critical source of fat for many

of Yellowstone National Park’s grizzly bears; they overturn

rocks to find them and consuming as many as 40,000 apiece

in a single day.

A.     bears; they overturn rocks to find them and consuming

as many as.

B.     bears; overturning rocks to find the insects, consum-

ing up to

C.     bears, overturning rocks to find them and they consume

as many as.

D.     bears, and they overturn rocks to find them and con-

sume up to

E.      bears, which overturn rocks to find the insects, consuming

as many as.

答案选e,我认为consuming修饰是不是在这里不是很清晰,c正不正确

第一题答案是A. personify + N.

第二道题目应为A

B. which 可指带lowering prices or (increasing supply and lowering prices), 产生歧义

on top of that, 该句子本想说,improved efficiency , demand, increasing demand and lowering prices 三者都是联系的,improved efficiency 通过促使increasing demand and lowering prices 从而stimulate demand, B 中, 这3者的联系没了, 尤其improved efficiency 与 increasing demand and lowering prices 的促使作用.

open to discuss.

第三题C不好

overturning rocks to find them and they consume 怎么能并列呢？个人认为E还是最佳答案

thanks very much,第一个中devastation and enslavement 应该是复数怎么不选e,疑问!!
