because和for的区别

更新时间2019-08-10 17:58:23

 

Because和for的用法不同之处

一、作为原因状语,because引导的原因状语从句位置灵活,而for引导的原因状语从句只可在主句之后,如:

1、The doctor looks tired because he sat up all night.=Because he sat up all night,the doctor looks tired 医生看上去很疲劳,因为他整晚都站着。

2、The doctor looks tired , for he sat up all night with the patient.医生看上去很疲劳,因为他整晚都站着。如:

二、由because引导的原因状语分句可以单独用来回答why引导的问句,而for引导的分句不行。

——Why does the doctor look so tired?为什么医生看上去那么累?

——Because he sat up all night.因为他整晚都站着。

三、作为原因状语,because前可带否定词或其他修饰语,还可带某些并列连词,而for分句不可。如:

The doctor looks tired, not because he isn’t feeling well, but because he sat up all night with the patient.医生看上去很疲劳,不是因为他不舒服,是因为他整晚都站着。


四、连词for可以引导一个句子,为上文陈述的况说明原因或提供理由,而because引导的原因状语从句通常引导从属分句,除用以回答why问句外不单独出现。如:

When I saw her in the river, I was frightened. For at that point the currents were dangerous.看到她呆在河里,我很害怕。因为从那里看,喝水很湍急。
