科技论文写作中but和however的使用区别

admin 2天前 11 0

在科技论文写作中,常用到but或者however,这两个单词基本意思一样,但是还是有一些区别的。如何区分这两个单词,合理使用but和however?

经常看到很多人在科技论文写作时,本来要表达的意思是but,但是却使用成了however。虽然but和however是一个意思,但是在语境不一样时,两者表达的意思可能存在差异。

but是一个连接词,它可以连接两个独立分句。however的使用更灵活了,它可能有更多的含义

例:I ate my apple. I was still hungry, however, I didn't eat again.

这句话等同于I ate my apple but I was still hungry. I didn't eat again.这句话的重点是苹果并不能充饥,不再吃苹果了是次要信息。

The point of the sentences is that the apple didn't satisfy the speaker's hunger and not eating again is just an extra detail.

例:I ate my apple. I was still hungry. However, I didn't eat again."

这句话等同于I ate my apple. I was still hungry but I didn't eat again.这句话的重点是我虽然我还是饿但是我决定不再吃苹果了,吃苹果是次要信息。

想像一下but就是一个单方向的箭头→,而however却可以是双方向的箭头,可以指向左←,也可以指向右→。因此however可以根据句子中的位置表达不同的意思,因此在使用however的时候,要比but更要在意其在句子中的位置。
