Question

3个单词的区别
over during in 后面加时间都是在 什么期间 可是却别是什么呢

Answer 1

注意over后只可以加sth,表示during sth,此时可与during互换.比如over the weekend= during the weekend, 但是over后面不能加时间,比如during the 1990s不能说成over the 1990s
during是指一个持续的过程,e.g. I learned swimming during the holiday.假期里我学会了游泳. He works in the garden during the day.他白天在花园里工作.
in是在…之内,在…之后,过…后. e.g. in the daytime , in spring ,in two months
注意,in 加时间可以表示将来时,e.g. I will come back in two days.两天之后我会回来,而during则不可以表示将来.
