The continental United States receives an average of 30 inches of precipitation a year; transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow of streams and rivers.

(A) transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, while the balance of 9 inches contributes to the flow

(B) even though transpiration from soil and from plants returns approximately 21 of the 30 inches to the atmosphere, the remainder of 9 inches contribute to the flowing

(C) although transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the balance of 9 inches contribute to the flowing

(D) with transpiration from soil and from plants to return approximately 21 inches to the atmosphere, the rest of the 9 inches contributes to the flow

(E) as transpiration from soil and from plants return approximately 21 of the 30 inches to the atmosphere, the rest of the 9 inches contribute to the flow
A中的while应该会产生歧义吧，同时和虽然。记得是OG上说的，...,while...时。可答案选A.谁能解释下。

B: the remainder of 9 inches 作主，谓动用单数，所以应该是 contributes

C: transpiration 作主，谓动用单数，所以应该是returns

D: with +n. +to do错误，with的独立主格形式为：

with +n. +n./adj/-ed/-ing

E.transpiration 作主，谓动用单数，所以应该是returns

呵呵，我问的是A中的while的歧义问题。

loverwy

while表转折，“但是”，“然而”

while也有同时的意思啊，记得是OG上说的歧义问题。

比如
OG131
Over 75 percent of the energy produced in France
derives from nuclear power, while in Germany it is just
over 33 percent.
(A) while in Germany it is just over 33 percent
(B) compared to Germany, which uses just over 33
percent
(C) whereas nuclear power accounts for just over
33 percent of the energy produced in Germany
(D) whereas just over 33 percent of the energy
comes from nuclear power in Germany
(E) compared with the energy from nuclear power in
Germany, where it is just over 33 percent

A的解释说while is somewhat  ambiguous,since it might indicate simultaneity rather than contrast.

哦买嘎

我觉得根据原文的意思，这两个过程是同时发生的，所以用while是正确的，其实每个词（包括汉语）都有好多个含义，如果都抠得这么细的话，那就没有正确的句子了。每个词只要在上下文的语境中能够表达出该意思就是正确的；while在这里不管是当“在。。时候”或是表示转折，都不会影响句子表达的意思。再者，即使把这个while算是一个错误，那么A选项也是这五个选项中错误的最少的一个，我们不应该选它吗？

while 表示同时最常见的是while doing
while+句子一般都表示虽然吧，逻辑上。

個人認為while在這是表達對比的涵意,所以用even though 或是 although 則改變句意
