重点中学英语语法讲义-连词

(3) 关于 for：是并列连词(其余三者为从属连词)，它有时可表示因果关系(通常要放在主句之后，且可与 because 换用)；有时不表示因果关系，而是对前面分句内容的解释或推断(也要放在主句之后，但不能与because 换用)。比较：

The ground is wet, for (=because) it rained last night. 地面是湿的，因为昨晚下过雨。

It must have rained last night, for the ground is wet this morning.  昨晚一定下过雨，你看今天早上地面是湿的。 (此句不能用 because 代 for)

3. although & though

两者均表示“虽然”，区别如下：

(1) 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。

(2) 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。

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

He talks as though he knew anything.  他夸夸其谈好像无所不知。

(4) 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。
