连词for的用法
1、for用作连词,主要表示理由,用于引起的分句对前面的话进行解释,常用逗号把它和前面的分句分
开。如:
She was angry, for she didn’t know French. 她生气了,因为她不懂法语。
He must be out, for there is no light in the room. 他准是出去了,因为屋里没有灯。
He shook his head, for he thought differently. 他摇了摇头,因为他有不同想法。
The days were short, for it was now December. 白天很短,因为这时已经是十二月。
We rarely stay in hotels, for we can’t afford it. 我们很少住旅馆,因为我们住不起。
You needn’t have watered the flowers, for it is going to rain. 你本不必浇那些花,因为就要下雨了。
He took the food eagerly, for he has eaten nothing since dawn.
他狼吞虎咽地吃了起来,因为他从天亮就没吃过东西。
He was busy packing, for he was leaving that night.
他那时正忙着打点行李,因为那天晚上他就要走了。
She does not go out in the winter, for she feels the cold a great deal.
她冬天不出门,因为他特别怕冷。
2、for表示结果通常不能放句首,也不能单独使用。
for表示原因时的四个“不能”
1、for引导的从句不能位于它所解释的动词之前:
Because it was wet he took a taxi. 因为下雨,他叫了一辆出租车。(这里不能用for)
2、for引导的从句不能位于not, but或任何连词之后:
He stole, not because he wanted the money but because he liked stealing.
他偷东西,并不是因为他想要钱,而是他有这种毛病。(这里不能用for)
3、for引导的从句不能用于回答问题:
—Why did you do it? 你为什么这么做?
—I did it because l was angry. 因为我生气才这么做的。(这里不能用for)
4、for引导的从句不能单单用来复述已讲过的话,而必须包括新的内容:
He spoke in French. She was angry because he had spoken in French.
他讲法语。因为他讲法语,她生气了。(这里不能用for)
但是说:
She was angry, for she didn’t know French.
她生气了,因为她不懂法语。(这里用for是正确的,也可用because)
注意:之所以有这些用法上的限定,其理由是for引导的从句不能直接说明某一特定动作发生的原因,而只能
提供一些起帮助解释作用的附加说明。例如:
The days were short, for it was now December. 天短了,现在已是12月了。
He took the food eagerly, for he has eaten nothing since dawn.
他狼吞虎咽地吃了起来,因为他从天亮就没吃过东西。
When I saw her in the river I was frightened. For at that point the currents were dangerous.
我看见她在河里时,吓坏了。那个地方水流非常危险。
注意:在口语中,for从句前常稍停一下。在笔语中,在此处常有一个逗号。有时也用一个句号断开,如最后
一个例子所示。上面三个例句中也可用becatse, 但用for更好些。
