although

although 与though的用法区别

一、用作连词

表示“虽然”，两者大致同义，可换用，只是although 比though 更为正式：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、用作副词

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”：

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。

三、用于习语

在as though(好像，仿佛)，even though(即使，纵然)等固定短语中不能用although：

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。

He is an honest man, I must say, even though I have opposed him. 尽管我反对过他，我还得说他是一个诚实的人。

She was always afraid of men, even though she had lots of boyfriends.尽管她有很多男朋友，她总是害怕男人。

四、用于倒装

though 引导的让步状语从句可用部分倒装的形式(注意：倒装后位于句首的名词之前不用冠词)，但although 一般不这样用：

Poor though I am, 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. 他虽是孩子，但干得很好。

另外注意：

1. although较正式，语气强

Although he was tired, he went on working.

2. although引导的从句放在主句前后均可，有时还可放在句中。

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。

Our car is old although it still runs well.

我们的车旧了，然而却很好开。

The war is over, although strong cunning enemy, or be eliminated.

战争已经结束，敌人虽然强大狡猾，还是被消灭了。

3. 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。

1.两词同义并可换用，但although语气较重，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.用though 时，可将强调的词前置，但although 不能。as也有此种倒装结构。如：

Poor though / as he is , he is happy.虽然他穷，但过得很愉快。

Child though / as 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. although 引导从句常指事实，不能指假设的情况，而though 引导的句子可表假设。当让步状语从句指某种假设情况时，通常用though,而不用although。如：

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。（假设）

Though everybody deserts you, I will not.

即使所有人都抛弃你，我也不会的。（假设）

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.although 只用作连词，不能作副词放在词尾，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。

5.though 可用于even though, as though 等结构，although则不能。如：Even though I fail, I'll keep on trying. 我纵然失败，仍会继续尝试下去。

You look as though (=as if ) you know each other. 看起来你们好像彼此认识。

6. although 和though 用作连词时不能和but连用，但可跟yet, still 等连用。如：

Although he lives alone, yet he is happy. = He lives alone, but he is happy. 他虽然单独生活，但很愉快。

7.though 常用于省略句。如：Though (he is) alone, he is happy.

区别：①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。

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……) 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。

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。

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。

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。

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。

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.

as,though,although的比较

As, though, although的用法 1. 用作连词，表示让步(意为：虽然，尽管)，要用于倒装句，且倒装后位于句首的名词通常不用冠词(等于though, 但语气 稍弱)。如： Child as [though] he was, he did quite well. 他虽是个孩子，但已干得很不错。 2. 用作关系代词，主要用法有二。如： (1) 用在such, same, as等之后，引导限制性定语从句。如： This is the same watch as I lost. 这块表跟我丢失的那块一样。 Such men as heard of him praised him. 听说过他的人都赞扬他。 (2) 单独用作关系代词，引导非限制性定语从句，可放在主句之前(常译为：正如)或之后(常译为：这一点)，且主从句之间一般要用逗号隔开。如： He was absent, as is often the case. 他缺席了，这是常有的事。 As was expected, he succeeded at last. 正如我们所料，他终于成功了。 3. 用来表示目的，下面两种句子结构都可以。如： 仔细写以便把每句话都写清楚。 正：Write carefully so as to make every sentence clear.

一、用作连词 1. 用作等立连词，使其前后的词、短语、分句相互对照，作“但是，然而，可是”解。例如： She is young but very experienced. 她虽然年轻但经验丰富。 2. 用于表示歉意的话语之后，表示谢绝或不赞成。例如： I'm sorry, but I disagree with you. 对不起，我不同意你的意见。 3. 用于两个并列的分句之间，与前面的否定词形成对比，作“无……而不……”解。例如：It never rains but it pours. 不雨则已，一雨倾盆。 I never go past that house but I think of my miserable life in the old society. 我走过那所房子时，没有一次不想起我在旧社会所过的悲惨生活。 二、用作介词 1. 与 no ， nobody ， nothing ， none ， who 等词连用，作“除……之外”解，用来排除同类中的一分子，或从整体中除去一部分。例如： Nobody knew her but me. 除我以外，没有人认识她。 Nothing but disaster would come from such a plan. 这个计划只能带来灾难，别无益处。 2. but 前面有 do 的某种形式时， but 后面的动词不定式要省略 to ；其前没有 do 的某种形式时， but 后面的不定式要带 to 。例如： We had no choice but to wait. 除了等待，我们别无选择。 He did nothing all day long but watch TV. 一整天，他除了看电视，别无他事可做。3. 与 last ， next 及 one ， two 等连用，作“倒数第二、第三”等解。例如： Jack was the last but one to arrive. 杰克是倒数第二个到达的。 三、用作副词 1. 意思上相当于 only ，后面跟名词或动词。例如： Tom is but a child. 汤姆只是个孩子。 We can but try now. 我们现在只有尝试一遍。 2. but 出现在 too … to …结构前面时，不定式含肯定意义。例如： I'm but too glad to go there with you. 我非常高兴和你一起去那里。 四、含 but 的习惯用语 1. but for ＝ without ，意为“要不是；如果没有”，意思上相当于一个虚拟条件句。例如： But for the rain (If it hadn't rained), we would have had a pleasant journey. 要不是天下雨，我们这次旅行就惬意了。 But for your help, we couldn't have carried out the plan. 如果没有你的帮助，我们不可能实现那个计划。 2. but that = except that ，意为“若非；要不是”，引导虚拟条件状语从句。例如：He would have helped me but that he was short of money at that time. 要不是他那时候没钱，他会帮助我的。 3. but then = on the other hand ，意为“不过；在另一方面”。例如： London is a noisy place, but then it's also a place where you get the best entertainment.

though 和although 的区别

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。 1.as far as、so far as 2.as long as、so long as 1.用于指距离，表示“直到……为止”之意时，as far as既可用于肯定句，也可用于否定句，但so far as只能用于否定句中。例如：We went as far as Lion Rock Tunnel. 我们一直走到狮子山隧道公路那儿。 They did not go as far as the others. 他们没有像其他的人走得那么远。 （此句的as far as可以改作so far as） （二）在表示“直到……程度”之意的借喻说法中，as far as和so far as都可使用，但前者不及后者用得普遍。例：she went so far as （or as far as）to call him a coward. 她甚至骂他是儒夫。 （三）在表示“就……而论”之意时，as far as和so far as可互换使用。例：As （or So）far as I koow，she will be away from Macao for two months. 据我所知，她将要离开澳门两个月。 As （or So）far as my knowledge goes，there is no such word in English. 据我所知，英语里没有这样一个字。 (四）在表示“只要”、“尽……所能”之意时，应用as far as，不用so far as。例：I'll do my utmost to help you as far as I can. 只要可能，我一定竭尽全力来帮你。Eric Partridge在他编著的Usage and Abusage 一书中写道（第44页），在用作比喻意义的叙述句里，so far as比as far as用得普遍，他举了这样一个例子：so far as I can see，your idea is admirable. 2.一、在表示during the whole time that(长达……之久)或while(只要)的含义时,往往用as long as。如: 1. they all continued their regard for me as long as they lived. 他们毕生都在关心着我. 2. For almost as long as Juanita could remember, adding, subtracting, multiplying, and dividing seemed as easy as breathing, and as natural. 在胡安妮塔的记忆中,加减乘除对自己来说早就是如同呼吸一样简单而自然了. 3. As long as there is life there is hope. 留得生命在,不怕没希望. 二、在
