首先，当though作从属连接词时，表示“虽然”、“尽管”、“即使”之意，与从属连词although相同，但在使用场合上有所不同。though比although使用得普遍得多。所以，当强调让步关系时多用although。另外，though还可以作副词；although只能是从属连词。although、even though和though可用于句首或带有动词的从句开头。
We bought the car although it was old.
虽然这辆车是旧的，我们还是买了下来。
Although it was dark，he still worked in the field.
天黑了，他依然在田里劳作。
Although the sun was shining it wasn't very warm.
尽管太阳高照，却不很暖和。
Although small，the kitchen is well designed.
厨房虽小，但设计巧妙。
Although/Even though/Though everyone played well，we lost the game.
We lost the game，although/even though/though everyone played well.
尽管每个人都打得不错，我们还是输了。
(一)although的让步语气比though强，大多用于正式的文体，指已成立的事实;though的语气较弱，一般指设想和假定的情况。例：
He wouldn't take an umbrella although it was already raining.
虽然当时已在下雨，他还是不愿意拿雨伞。（事实）
He wouldn't take an umbrella though it should rain cats and dogs.
虽然有可能会下大雨，他还是不愿意拿雨伞。（假设）
但是，这种用法区别的讲究却渐行渐远。
Though [Although] it was raining，we went there. 虽然下着雨，但我们还是去了那儿。
Though [Although] it was barely four o’clock，the lights were already on. 尽管才四点钟，灯已经亮了。
Though [Although] we are poor，we are still happy. 我们虽然穷，仍然很快活。
(二)although在句中大都放在句首的位置，如放在句中(如上面一例)，则表示强调的意味;though放在句首和句中均可。though若要加强语气时，可将位置移后，构成异常语序的让步状语从句；注意：倒装后位于句首的名词之前不用冠词，但 although 一般不可以构成异常语序的用法：
Urgent as/though the message is，it is impossible to send it there in time.
消息很紧急，但不可能及时送到。
下辈子，我们依然还是好朋友：In the next life, we will still be best friend.We will still be best friends in the next life.我觉得这样翻译比较确切，用 will 比用 are 更适合。自己认真翻译的，有问题请追问。
Child as/though he was，he faced the dangerous situation calmly.
尽管还是个孩子，但他能冷静地面对危险情况。
Poor though I am，I can afford it.（Though I am poor，I can afford it.）
我虽穷，但这东西还是买得起的。
Child though he was，he did quite well. (Though he is a child，he did quite well.)
他虽是孩子，但干得很好。
Hard as/ though he works，he makes little progress. (=Though he works hard，he makes little progress.)
尽管他学习很努力，但几乎没取得什么进步。
(三)although 只能作从属连词使用;though除作从属连词外，还可用作副词，表示“然而”、“但是”、“可是”、“不过”等义，这时候，though一般放在句末。例：
Our team lost. It was a good game though.
我们队输了，可是这也不失为一场好球。
We are still friends，though，which is good.
不过我们仍然是朋友，这令人感到欣慰。
He said he would write to her. He didn’t，though.
他说过他要给她写信的，但是他却没有写。
It’s hard work; I enjoy it though. 工作很辛苦，可是我乐意干。
He is looking fit，though. 但他看起来很健康。
You can count on him，though. 不过你可以指靠他。
（四）在从属连词though(although)之后绝不可与but连用；中国人由于受汉语“虽然…但是…”的影响，常犯though(although)之后与并列连词but连用的错误。见下例：
Though the idea may be dead，but it is far from being buried. (错)
我们永远是朋友英文：We are always friends 1、We are still friends, though, which is good. 不过我们仍然是朋友，这令人感到欣慰。2、He's made a lot of new friends. 他交了许多新朋友。3、We've been friends。
Though the idea may be dead，it is far from being buried. (对)
尽管这种思想可能已无人相信，但还远没被人遗忘。
特别值得说明的是，从属连词虽然不可以和并列连词联用；但是，却可以和副词yet，still，nevertheless等联用：
尽管他被认为是一位伟大的作家，但他的作品并没有被广泛阅读。
Though he is poor，yet he is satisfied with his situation.
尽管他很穷，但他对他的境况是满意的。
Though [Although] admission was free ，nevertheless few people attended the lecture.
尽管免费入场，但听演讲的人却不多。
Alhough he was ill，yet/still/nevertheless he managed to look careful.
虽然他病了，但他尽力显出很注意的样子。
Though the sore be healed ，yet a scar may remain.
伤口随愈合，伤疤却永留。
不是，而是We are still good friends.
另一点要注意的是，词组as though、even though的though不能改作although，因为它们是固定词组。
（六）even though/even if引导的让步状语从句，although却不可以这样用
这两个短语表示语气更强的让步，常常意为“再退一步说”。Even though更加强调对“既成事实”的让步，even if更强调对“假设”的让步。
Even though we are far away, we are still friends
I'll get there even if/even though I have to walk all the way.
即使得一路走着去，我也要走到那里。
Even if he is poor，she loves him.
即使他很穷，但她还是爱他。（假设他是个穷鬼）
Even though he is poor，she loves him.
尽管他很穷，但她还是爱他。（事实他就是个穷鬼）
（七）在 as though(好像，仿佛)，even though(尽管，纵然)等固定短语中不能用 although：
Rusty nodded as though she understood the old woman
拉斯蒂点点头，好像听懂了那位老妇人的话似的。
She closed her eyes as though she were tired. 她闭上眼，仿佛很疲劳似的。
We felt as though we had witnessed the whole thing. 我们感到仿佛目击了整个这件事似的。

他们看样子会离婚。

尽管她知道这错了，她也不肯改变。

I like her，even though she can be annoying at times.
尽管她有时可能很烦人，我还是喜欢她。

我喜欢她，虽然有时烦得真想把她掐死。

哪怕失败，我也要试一下。
尽管她坐得起出租汽车，但她从未坐过。
