whereas + while

According to findings derived from functional magnetic resonance imaging (MRI), the area of the brain in which a second or third language is stored depends on the age of the language learner; whereas each language occupies a distinct area of the brain in an adult learner, language areas overlap in a young child.

 

 

1. whereas each language occupies a distinct area of the brain in an adult learner,
           
2. whereas for adults each language occupies a distinct area of the brain and
           
3. each language occupies a distinct area of the brain when they are learned by an adult, while
           
4. each language in adults occupied a distinct area of the brain, while
           
5. each language occupying a distinct area of the brain for an adult learner, and

while, whereas, or although
The use of "while" to show contrast is common and accepted in informal usage. In
formal writing, however, "while" should be reserved to show that two or more
events occur at the same time. In the following sentence, the two events are
occurring simultaneously.

Measurements were taken while the specimen was rotating in the rig.
For comparisons and contrasts, "whereas" and "although" should be used instead
of "while."

Positions are logged manually, whereas temperatures and pressures are recorded
automatically by the thin-film sensors.
These two events happen in different ways. They do not necessarily occur at the
same time.

Although positions are logged manually, temperatures and pressures are recorded
automatically by the thin-film sensors.
The meaning of this sentence is similar to the previous one, but it places more
emphasis on the differences between the two events.

Indiscriminate use of "while" where "whereas" or "although" would be more
appropriate can even result in ambiguity and misunderstanding:

While my cat, Princess, eats quickly, she enjoys a leisurely stroll.
Does she do both at the same time? Using "whereas" or "although" in this sentence
would clear up the confusion.



In each sentence, select the best choice for formal writing:

While /Although the method is efficient for most applications,
it can produce errors when small, irregularly shaped specimens are tested.
Place the sample into the rig while / whereas the power is off.
The Structures Division had responsibility for the fan blade design, while /whereas
the Materials Division was to develop the composite material for the blade. (The two
projects are not necessarily happening at the same time.)
While /Although the experiment was thermal cycling, an inert atmosphere was
maintained to avoid oxidation of the aluminum framework.
The single-crystal material is somewhat stronger, while /whereas the composite is
significantly lighter.
Make sure that excessive pressure is not applied while / whereas the surfaces are in
contact with each other.

从这里的解释可以看出来，

while一般用在非正式英语中。正式英语中，while表示对比概念的时候，两个事物要是同时发生的。（进一步说明了while表达两个动作同时发生的特性）

whereas则是重点表示事物的强对比性，而两者不一定是同时发生的。

在当同时出现while和whereas，而句子是要表达两者的强对比概念时，应该使用whereas

而although是表示让步的意思。

用while/whereas/although 主要还是看句子意思。强调同时发生用while，强调对比用whereas，表让步用although

OG有一题解释道（131T）while 和 whereas 都可以做对比（A,B对比）。但是while是容易产生歧义的，因为还可以表示A,B两事件的同时性，而并不表示对比。

顶一个 我看见OG13 的130题的解释中也提到了 while is indicae simultaneity rather than contrast而 whereas表示的是强对比~
再问一句题外话。。。although这个词是必须放句首么？
