原因状语从句 | because、for和as的用法区别
能用because-分句之前可用否定词或其他修饰语,这种分句之前还可以用某些并列连词,但for-分句不可以,同样的since- / as-分句也不可以。关于这一点,我们再补充例子: I went to the state university chiefly because the tuition was cheaper. She didn’t want to go to Africa, probably because the weather is too hot. I’m going there tomorrow because I have to, not because I want to. 由于since- / as-分句通常表示已知的原因,所以常常出现于句首,这状语从句又是它们与for-分句用法上不同之处。 例如: As China is a long, narrow country, the temperature varies considerably from north to south. Since he had a certain talent for composition, his English master encouraged him to write little pieces for the college magazine. 当然since- / as-分句也可位于句尾,作为一种补充说明。 例如: I’ll have you ask someone else, since you can’t answer this question. He saw her, as they were both getting off the bus at the same time. 看完了小编整理的语法解析,大家对打败because、as和for这三个“小怪物”是不是多了几分信心呢?赶快收藏起来吧~
