非常感谢2love2live，我来把它贴全

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.

我想你主要问的是都做although的词义

查了一下朗文和韦氏，
longman:
whereas (shows an opposite 表示相反的情况)， but , although
they want a house, whereas we would rather live in an apartment.

while: although , whereas
their country has plenty of oil, while ours has none.
朗文上没有给出二者的区别

韦氏
while: when on the other hand
easy for the expert, while it is dangerous for a novice.
in spite of the fact that
while respected, he is not liked.

whereas: while on the contrary

似乎做尽管讲的时候二者没有什么必然的区别。
请继续讨论

超强啊！

从上面解释，我们是不是可以这样认为，那就是如果while在gmat里面作为“然而”来解释时，就是错误的选项？？

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.

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

着题中如何区别WHILE和WHEREAS、？
