在as though, even though 中一般不可用although 代替。

同时although 不可当副词用，而though 则可。

Although it's raining, they are still working in the field.虽然在下雨，但他们仍在地里干活。

Short though it is, the article is very important.那篇文章虽然很短，但很重要。

注意：though 还可用作副词，意为“可是，然而”，置于句末。

He said he would come; he didn't, though.他说他会来，可是没有来。

2. even though/ even if 引导的让步状语从句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 更强调对“既成事实” 的让步：Even though he is poor, she loves him. (= He is poor, yet she loves him.)尽管他很穷，但她还是爱他。

中考英语-原因、结果、目的状语从句讲解+练习状语从句总结一、原因状语从句(1)原因状语从句通常由because, since, as, for引导。

(2)because表示直接原因，语气最强。

because引导的原因状语从句多放在主句之后。

回答由why提出的问题，只能用because。

此外，because和so不能同用在一个句子里。

例如：------Why aren’t going there?------Because I don’t want to.since引导原因状语从句，相当于now that，意思是“因为……，既然……，鉴于……”。

例如：Since the rain has stopped，let’s go for a walk. 既然雨停了，我们出去散散步吧。

as和since语气较弱，一般用来表示明显的原因。

由as和since引导的原因状语从居多放在句首。

例如：As he has no car, he can’t get there easily.Since we have no money, we can’t buy it.(3)for表示所说的理由是一种补充说明,for引导的从句一般不放在句子的开头。

如:I decided to stop and have lunch, for I was feeling quite hungry.练习：I was late for class yesterday _______ there was something wrong with my bike.He took off his coat _______ he felt hot.you can’t answer the question, I’ll ask someone else.二、结果状语从句(1)结果状语从句由so…that, such…that, so that引导。
