1、although用于连词，although不能与but一起连用。 2、although， 尽管；虽然；但是；然而。 3、例：Although he is known to only a few, his reputation among them is very great.尽管只有几个人知道他，但是他在他们之中的名声很大。 4、He was in love with her, although a man seldom puts that name to what he feels.他爱上了她，虽然一个男人很少用这个词来形容他的感受。 5、Although theyre expensive, they last forever and never go out of style.尽管它们贵，它们永远耐用并且永不过时。

1、用法不同：though可以作副词使用；而although不可以作副词使用。 2、使用场合不同：though一词，没有那么正式，因此常用于口语；而although一词，较为正式，因此常用于正式场合。 3、意思不同：though有不过、即使等意思；而although有虽然、尽管等意思。 4、充当成分不同：在英语句型中，though既可以充当连词成分，又可以充当副词成分；而although只可以充当连词成分。

区别：①although和though同义，在一般情况下，可以互换使用。只是though较普遍，常用于非正式的口语或书面语中，而although则较为正式。另外although语气比though重，常用以强调让步概念。 e.g. Though/Although my car is very old, I don"t want to buy a new one. 虽然我的汽车很旧，但我不想买一辆新的。 He insisted on doing it although I warned him not to. 虽然我警告他不要做，但他仍然坚持要做。 ②even能和though组合表示强调，但even不能和although组合。因此，不能说even although,在这里even though=even if(no matter if; though即使……也……) e.g. Even if/Even though we could afford it, we wouldn"t go abroad for our vocation. 即使我们付得起这笔钱，也不出国度假。 ③当让步状语从句指某种假设情况时，通常用though,而不用although。 e.g. Though all the world were against me, I should still hold to my opinion. 就算全世界都反对我，我还是坚持我的立场。 Though everybody deserts you, I will not. 即使所有人都抛弃你，我也不会的。 ④though可以独立用作副词，常放在句末，意为all the same (还是；仍然)或however(可是；然而)，而although无此用法。 e.g. She didn"t tell me what she had done, but I know it though. 她没有告诉我她所做的事情，但我还是知道了。 It"s hard work. I enjoy it, though. 工作很苦，可是我喜欢。 ⑤though引导让步状语从句时可以倒装，而although从句则不能。 e.g. Bravely though they fought, they had no chance of winning. 虽然他们打得很勇敢，但还是没有机会获胜。 相同点：①在although和though引导的让步状语从句中，主句里不可用but,若要强调前后两部分的对比意义，可在主句前加yet或still。 e.g. Although/Though he has a lot of money, yet/still he is unhappy. 他虽然有很多钱，但并不幸福。 ②although和though引导让步状语从句时，常采用省略形式。 e.g. Although tired (=Although he was tired), he kept on working. 虽然很疲劳，但他继续工作。 The problem, though complicated(=though it is complicated), can be solved without much difficulty. 这个问题虽然复杂，但解决起来不会有很大困难。

　　下面我为大家介绍Although的一些用法： 　　1.表示“虽然”时，不要根据汉语习惯，在后面使用连词 but, 不过有时它可与 yet, still, nevertheless 等副词连用。如： 　　他虽然年纪很大了，但还很强壮。 　　正：Although he is very old, (yet) he is quite strong. 　　误：Although he is very old, but he is quite strong. 　　但是在一定的上下文中，类似下面的 although 与 but 连用的 句子 是可能的 (注意 but 引出的句子在 although 从句之前) 。如：But Ididn"t know that then, although I learned it later. 但我当时的确不知道此事，尽管后来还是知道了。 　　2. 不能用于 as though (好像)，even though (即使) 等习语中代替 though, 也不用于让步状语的倒装形式中。 　　3. 若主从句主语相同，且从句谓语含有动词be, 可将从句主语和动词 be 省略。如：Although (he is) quite young, he knows a lot. 虽然很年轻，但他很懂事了。 　　In any case, she was very lovablealthough not at all tidy. 不管怎么讲，她还是很可爱的，尽管一点也不爱干净。 　　4. 有时用于主句之后，起补充说明的作用，相当于 however, but。如：He is poor-- although he is well contented. 他很穷，然而却能知足常乐。 　　The price increase will obviously be unpopular, although it"s unlikely to reduce demand. 价格升高显然会不受人欢迎，然而这不大可能会降低人们的需求。

although和though的区别：1、语气不同两词同义并可换用，但although语气较though更重，通常放在句首并用于正式场合。如：I"d quite like to go out,(al)though it is a bit late.我很想外出，虽然为时稍晚。Although it was snowing,it was not very cold.虽然下着雪，但并不很冷。2、强调词位置用though时，可将强调的词前置，但although不能。如：Poor though he is,he is happy.虽然他穷，但过得很愉快。Child though she was,the actress was drawing a crowd.尽管还是个孩子，这个女演员却引起了人们的注目。（child前无冠词a）3、从句性质不同although引导从句常指事实，而though引导的句子可表假设。如：Let"s start as arranged though it rains tomorrow.即使明天下雨，咱们也按预定的计划出发吧。（假设）He was not unhappy although he had to live alone.虽然得一个人生活，他毫无不快之感。（事实）4、用作副词although只用作连词，而though除作连词外，还可用作副词，常置句末，句子较长时，也置于句中。如：It"s hard work,I enjoy it though.这是苦差事，可我干得颇有乐趣。There"s no excuse,though,for hurting her feelings.伤到她的感情一事，还是不可原谅。

一、词性方面although只能作连词，though不仅可以作连词，而且还可以作副词，含义是“不过，然而”。例句1：Although/Though he is young,he looks very old.(虽然他年纪很小，但是看起来很老。)句子中although或though作从属连词，引导让步状语从句。例句2:He had a fight with her yesterday.They are still good friends now,though.(昨天晚上他和她打了一架，不过他们现在仍然是好朋友。)在这个句子中，though是副词。二、用法方面1、although所引导的让步状语从句一般用陈述语气，从句所说的内容常指事实，而不指假想；而though所引导的从句却可以用来表示假设或推测，从句既可以用陈述语气，也可以用虚拟语气。例句1：Although the box is very small,it is really useful.(尽管这个箱子很小，但它真的非常有用。)在这里although引导的从句陈述的是事实而非假设。例句2：Help her though she may refuse.(帮帮她吧，即使她可能拒绝。)在这里though引导的从句用来表示假设或推测。2、although常用于正式文体中，不能和even、as连用；though常用于口语和非正式文体中，可以和even、as连用。例句1：He won"t go there,even though the library is not far.(虽然图书馆不远，但他不会去那里。)例句2：It looks as though she has gone home.(看起来好像她回家了。)3、although引导的状语从句不能使用倒装形式；though引导的状语从句位于句首时，既可以使用倒装形式，也可以用正常语序。例句1：Although/Though he is poor,he is very happy.(尽管他很穷，可是他很快乐。)这里although/though引导的让步状语从句采用正常语序，此时although和though可以互相替换。例句2：Poor though he is,he is very happy.(尽管他很穷，可是他很快乐。)在这里，though引导的让步状语从句Poor though he is采用了倒装语序，此时就不能用although来代替though。

区别如下：1、使用场合不同although和though同义，在一般情况下，可以互换使用。只是though较普遍，在文体上不如 although 正式，常用于省略句，或引出倒装语序的让步状语从句。而although通常置于句首并用于正式场合。另外although语气比though重，常用以强调让步概念。2、词性不同although 一般不用作副词，而 though 可用作副词，且一般放在句末(不放在句首)，意为“可是”、“不过”。例句：Although the sun was shining it wasn"t very warm.翻译：尽管太阳高照，却不很暖和。例句：Anne was fond of Tim, though he often annoyed her.翻译：安妮喜欢蒂姆，虽然他经常使她心烦。扩展资料例句Although he is known to only a few, his reputation among them is very great虽然知道他的人不多，但他在这些人中名声却很响。Although I was only six, I can remember seeing it on TV.虽然那时我只有6岁，我依然记得在电视上见过它。I look back on it as the bloodiest ( though not literally) winter of the war .我现在回想起来，觉得那是战时最血腥的（但并非字面意义上的）一个冬天。I like him. Though he makes me angry sometimes .我喜欢他，不过他有时惹我生气。

although尽管through通过

1.although一般引导让步状语从句.比如Although he was tired ,he still worked hard.尽管他已经退休，他还恪尽职守，兢兢业业。2.although引导的从句放在主句前后均可,有时还可放在句中. 例如：Although many difficulties are still ahead, we are determined to make greater achievements. 尽管在前面的道路上还有许多困难,但是,我们决心要取得更大的成就. He often helps me with my English although he is quite busy. 尽管他相当忙,但是还常常帮我学英语.4. although引导的从句不能与but, however连用,但可与yet, still连用.不能说：Although he was old, but he worked hard. 应把but去掉.当然,保留but而去Although也可. 5.在让步状语从句中,although一般可以用though和while来替换.6.在时间，条件，地点，方式，让步等状语从句中，如果从句主语和主句主语相同，或者从句主语是it时，从句的主语和谓语动词的一部分经常省略。例如Although (he was ) tired,Tom kept on working till late at night.

Although I am very tired, I keep working without rest.

通常两者可以互换，当though用于倒装是不可用although

though有三个词性，副词、连词、介词。although就有连词的词性。

although和though的区别：1、语气不同两词同义并可换用，但although语气较though更重，通常放在句首并用于正式场合。如：I"d quite like to go out,(al)though it is a bit late.我很想外出，虽然为时稍晚。Although it was snowing,it was not very cold.虽然下着雪，但并不很冷。2、强调词位置用though时，可将强调的词前置，但although不能。如：Poor though he is,he is happy.虽然他穷，但过得很愉快。Child though she was,the actress was drawing a crowd.尽管还是个孩子，这个女演员却引起了人们的注目。（child前无冠词a）3、从句性质不同although引导从句常指事实，而though引导的句子可表假设。如：Let"s start as arranged though it rains tomorrow.即使明天下雨，咱们也按预定的计划出发吧。（假设）He was not unhappy although he had to live alone.虽然得一个人生活，他毫无不快之感。（事实）4、用作副词although只用作连词，而though除作连词外，还可用作副词，常置句末，句子较长时，也置于句中。如：It"s hard work,I enjoy it though.这是苦差事，可我干得颇有乐趣。There"s no excuse,though,for hurting her feelings.伤到她的感情一事，还是不可原谅。

区别如下：1、使用场合不同although和though同义，在一般情况下，可以互换使用。只是though较普遍，在文体上不如 although 正式，常用于省略句，或引出倒装语序的让步状语从句。而although通常置于句首并用于正式场合。另外although语气比though重，常用以强调让步概念。2、词性不同although 一般不用作副词，而 though 可用作副词，且一般放在句末(不放在句首)，意为“可是”、“不过”。例句：Although the sun was shining it wasn"t very warm.翻译：尽管太阳高照，却不很暖和。例句：Anne was fond of Tim, though he often annoyed her.翻译：安妮喜欢蒂姆，虽然他经常使她心烦。扩展资料例句Although he is known to only a few, his reputation among them is very great虽然知道他的人不多，但他在这些人中名声却很响。Although I was only six, I can remember seeing it on TV.虽然那时我只有6岁，我依然记得在电视上见过它。I look back on it as the bloodiest ( though not literally) winter of the war .我现在回想起来，觉得那是战时最血腥的（但并非字面意义上的）一个冬天。I like him. Though he makes me angry sometimes .我喜欢他，不过他有时惹我生气。

作为连词although 和 though 通常可以互换使用：Although （或 though ） 尽管她微笑着,她却在生气.Although常放在从句的开头（如前面例句）,而though 可以出现在其它位置,当用来连接词语或短语时更为常用,如尽管穷一些却更有头脑 或在下面这种结构中 尽管 （不用 although ） 我很喜欢歌剧,我也不愿这个周末一直坐等到 打铃 散场.As conjunctions,although and though are generally interchangeable:Although (or though ) she smiled,she was angry.Although is usually placed at the beginning of its clause (as in the preceding example),whereas though may occur elsewhere and is the more common term when used to link words or phrases,as in wiser though poorer,or in constructions such as Fond though (not although ) I am of opera,I"d rather not sit through the Ring cycle this weekend.

区别：①although和though同义，在一般情况下，可以互换使用。只是though较普遍，常用于非正式的口语或书面语中，而although则较为正式。另外although语气比though重，常用以强调让步概念。 e.g. Though/Although my car is very old, I don"t want to buy a new one. 虽然我的汽车很旧，但我不想买一辆新的。 He insisted on doing it although I warned him not to. 虽然我警告他不要做，但他仍然坚持要做。 ②even能和though组合表示强调，但even不能和although组合。因此，不能说even although,在这里even though=even if(no matter if; though即使……也……) e.g. Even if/Even though we could afford it, we wouldn"t go abroad for our vocation. 即使我们付得起这笔钱，也不出国度假。 ③当让步状语从句指某种假设情况时，通常用though,而不用although。 e.g. Though all the world were against me, I should still hold to my opinion. 就算全世界都反对我，我还是坚持我的立场。 Though everybody deserts you, I will not. 即使所有人都抛弃你，我也不会的。 ④though可以独立用作副词，常放在句末，意为all the same (还是；仍然)或however(可是；然而)，而although无此用法。 e.g. She didn"t tell me what she had done, but I know it though. 她没有告诉我她所做的事情，但我还是知道了。 It"s hard work. I enjoy it, though. 工作很苦，可是我喜欢。 ⑤though引导让步状语从句时可以倒装，而although从句则不能。 e.g. Bravely though they fought, they had no chance of winning. 虽然他们打得很勇敢，但还是没有机会获胜。 相同点：①在although和though引导的让步状语从句中，主句里不可用but,若要强调前后两部分的对比意义，可在主句前加yet或still。 e.g. Although/Though he has a lot of money, yet/still he is unhappy. 他虽然有很多钱，但并不幸福。

though有三个词性，副词、连词、介词。although就有连词的词性。

区别：①although和though同义，在一般情况下，可以互换使用。只是though较普遍，常用于非正式的口语或书面语中，而although则较为正式。另外although语气比though重，常用以强调让步概念。 e.g. Though/Although my car is very old, I don"t want to buy a new one. 虽然我的汽车很旧，但我不想买一辆新的。 He insisted on doing it although I warned him not to. 虽然我警告他不要做，但他仍然坚持要做。 ②even能和though组合表示强调，但even不能和although组合。因此，不能说even although,在这里even though=even if(no matter if; though即使……也……) e.g. Even if/Even though we could afford it, we wouldn"t go abroad for our vocation. 即使我们付得起这笔钱，也不出国度假。 ③当让步状语从句指某种假设情况时，通常用though,而不用although。 e.g. Though all the world were against me, I should still hold to my opinion. 就算全世界都反对我，我还是坚持我的立场。 Though everybody deserts you, I will not. 即使所有人都抛弃你，我也不会的。 ④though可以独立用作副词，常放在句末，意为all the same (还是；仍然)或however(可是；然而)，而although无此用法。 e.g. She didn"t tell me what she had done, but I know it though. 她没有告诉我她所做的事情，但我还是知道了。 It"s hard work.

能

although……，but……是不可以连用的如果要强调一下，可以用although……，sb. still……

任意去掉although和but中的一个。由于在同一句中既用了从属连词although，又用了并列连词but，使得该句一半像复合句，一半像并列句，从而导致错误。although是从属连词，but是并列连词，它俩放在一起，会造成语法上冲突，这就是：although和but不能连用的根本原因。

区别如下：1、使用场合不同although和though同义，在一般情况下，可以互换使用。只是though较普遍，在文体上不如 although 正式，常用于省略句，或引出倒装语序的让步状语从句。而although通常置于句首并用于正式场合。另外although语气比though重，常用以强调让步概念。2、词性不同although 一般不用作副词，而 though 可用作副词，且一般放在句末(不放在句首)，意为“可是”、“不过”。例句：Although the sun was shining it wasn"t very warm.翻译：尽管太阳高照，却不很暖和。例句：Anne was fond of Tim, though he often annoyed her.翻译：安妮喜欢蒂姆，虽然他经常使她心烦。扩展资料例句Although he is known to only a few, his reputation among them is very great虽然知道他的人不多，但他在这些人中名声却很响。Although I was only six, I can remember seeing it on TV.虽然那时我只有6岁，我依然记得在电视上见过它。I look back on it as the bloodiest ( though not literally) winter of the war .我现在回想起来，觉得那是战时最血腥的（但并非字面意义上的）一个冬天。I like him. Though he makes me angry sometimes .我喜欢他，不过他有时惹我生气。

though/although/as的区别为：含义不同、用法不同、侧重点不同。一、含义不同1.though释义：conj. 虽然；尽管2.although释义：conj. 然而；可是3.as释义：conj. 因为；像；当 ... 之时；像 ... 一样；结果；尽管二、用法不同1.though用法：though引导让步状语从句时表示一种假设的情况或含有推测的意味，从句的谓语动词可用陈述式，也可用虚拟式，有时为了强调让步的意义，可采用倒装语序。2.although用法：although的基本意思是“尽管，虽然”或“然而，但是”，常用于引导陈述语气的让步状语从句，且引导的句子常指事实，而不指设想。3.as用法：as还可表示原因，作“因为,既然”解，引导原因状语从句，表示不说自明的原因或理由，语气较轻，是附带提及，不加强调。as引导的从句可放在主句之前(表示原因不明显)，也可放在主句之后(表示原因明显)。三、侧重点不同1.though解析：在用though连接的从句中，谓语是be,而从句的主语与主句的主语相同时，从句的主语与be可同时省略。2.although解析：although可置于句首此时多用逗号与主句分开，也可置于句末此时用不用逗号均可，也可用于句中表强调。3.as解析：as可表示让步，作“尽管”解,引导让步状语从句。当主句的谓语动词是be或其他系词的限定形式时，常用于“名词形容词，过去分词+as+主语+be其他系词”的限定形式名词位于句首时一律不用冠词。

although和though的区别：1、语气不同两词同义并可换用，但although语气较though更重，通常放在句首并用于正式场合。如：I"d quite like to go out,(al)though it is a bit late.我很想外出，虽然为时稍晚。Although it was snowing,it was not very cold.虽然下着雪，但并不很冷。2、强调词位置用though时，可将强调的词前置，但although不能。如：Poor though he is,he is happy.虽然他穷，但过得很愉快。Child though she was,the actress was drawing a crowd.尽管还是个孩子，这个女演员却引起了人们的注目。（child前无冠词a）3、从句性质不同although引导从句常指事实，而though引导的句子可表假设。如：Let"s start as arranged though it rains tomorrow.即使明天下雨，咱们也按预定的计划出发吧。（假设）He was not unhappy although he had to live alone.虽然得一个人生活，他毫无不快之感。（事实）4、用作副词although只用作连词，而though除作连词外，还可用作副词，常置句末，句子较长时，也置于句中。如：It"s hard work,I enjoy it though.这是苦差事，可我干得颇有乐趣。There"s no excuse,though,for hurting her feelings.伤到她的感情一事，还是不可原谅。
