一、一般情况下，while在表示让步语义时与although同义，两者可以互用。
1.它们引导的让步状语从句都表示与主句中的某一动作或状态有着意义上的对比。如：
(1) While this is true of some, it is not true of all. 虽有一部分是真的，但不见得全都是真 的。
(2) While I feel great sympathy for you, I can’t really do very much to help. 虽然我对你深为同情,但我实在是帮不上什么忙。
(3) They are generous although they are poor. 他们虽然贫穷却很大方。
(4) Although I appreciate her reasoning,I reject her conclusions. 虽然我欣赏她的推理能力,却不能接受她的推论。
2. while和although引导的让步状语从句都不能和but连用，但可以跟nevertheless或yet连用。 如：
(1) While I admit I did it, (nevertheless) I didn’t mean to. 尽管我承认这件事，但我并不是故意的。
(2)Although admission was free, (nevertheless)few people attended the lecture. 尽管免费入场，但几乎没什么人去听演讲。
(3)Although (he was) riously wounded, (yet) he refud to leave the battle line. 他虽然身负重伤,但坚持不下火线。
它们引导的让步状语从句都可以省略与主句相同的主语和与其相应的be动词。如：
(4) While (I am)told you are wrong, I am sure you are honest. 尽管我知道你错了，但我还是相信你很诚实。
(5) Although (she was) not yet six months old, she was able to walk without support. 她虽然还不到6个月, 但已能不用搀扶走路了。
二、在一些特定的语境和语体中，这两个词在用法上还是有细微差别的。
1. while引导的状语从句在大多数情况下置于句首；而although引导状语从句，可置于句首也可置于句中或句末。如：
(1) While we don’t agree, we continue to be good friends. 尽管我们意见不一致，但我们仍是好朋友。
(2) While the ways ud are quite different,the result is similar. 虽然所用方法完全不同，但效果却相似。
(3) Although young Tom comes of a musical family, he doesn’t like singing. 虽然年轻的汤姆出身于音乐之家，但他不喜欢唱歌。
(4) We’ll try to finish the work in time although we are short of hands. 虽然缺少人手，我们还是要按时完成这项工作。

(5) Common salt, although (it is) dissolved in water,does not change its chemical properties. 尽管食盐溶于水，但其化学性质不变。
2. although引导的状语从句常含常有“not”一词，修饰主句或纠正一个错误的概念；而while一般不这样用。如：
(1)I have a lot of my grandfather’s features although I’m not so tall as he was. 虽然我不及我祖父个子高，但相貌却与他很相似。

3. but不可连用，但but although可以连用，且往往置于句首；而while没有这种用法。如:
(1) But although the situation was clearlydang-erous, the public was not at all happy with the idea of a government police force. 尽管局势是明显地危险,可是老百姓对政府动用警力的做法仍很不满意。
4. while引导的让步状语从句在意义上一般与主句的对比不太强烈，即主句与从句只是部分不一致；而although在表示让步语义时是最为通用的从属连词，所引导的从句往往使主句内容含有似乎使人感到意外或料想不到之意。以下例句中while和although不可换用。
(1) While I admit his good points, I can e his shortcomings. 尽管我承认他的优点，我也能看到他的缺点。 爪子的英文
(2) While I like the color of the hat, I don’t like its shape. 虽然我喜欢这顶帽子的颜色，但不喜欢这种式样。

(5) Smith kept her coat on although it was warm in the room. 尽管房间里很暖和，可史密斯仍旧穿着外套。 朱陶
5.这两个连词都可用于让步结构，但两者所连接的句子的主从关系恰好相反。比较：
