It was therefore rather difficult for them to find time to do all their other duties.
...at still others,they do not have either to sTOP or to go slow,....
老师,副词可以如此放吗,这是小说排版问题,还是副词地方的灵活性?
therefore为副词作连接性状语,一般坐落于句首,逗号隔开。但也可以放在中位状语的地方,前后用逗号隔开。偶尔也不需要逗号。
some..., others..., still others. 在说了others 之后,还有另外的,则用still 修饰others。
以上二种状况都是标准的英语,不是排版错误。
