during summer holidays 与IN的区别?

题目

during summer holidays 与IN的区别?
DURING
IN
之间的区别是什么?

答案

1.during和in都可以加上一段时间,即during/in + some time,意思是“在...期间”.
2.两者主要区别如下：
1）during强调在整个期间都存在或发生的状态或动作；而in更多强调在期间某个时间所发生的动作.
如：I was in Beijing during the 1980s.
I went to Beijing many times in the 1980s.
2) 最关键的区别在于：如果后面加的并不是明显的时间状语词语,而是能延续一段时间的活动名词,如holiday,stay,visit,process等时,用during而不用in.
如：I felt happy during my stay in Beijing last year.
