date与day  date和day都指“日期一日”，细微区别如下。 1.date的意思是“日期”，指某事过去或将来发生的年月日。比如： What's the date today?今天是几号？I can't come on that date.那个日子我来不了。The official launch date is in May.正式的发行日期是在五月。The date of the election was fixed.选举的日期定下来了。 2.day的意思是“一日，白天”，它指从日落到的“白昼”，它也指一昼夜。比如： I saw Tom three days ago.我三天前见过汤姆。‘What day is it today?’ ‘Monday.’“今天星期几？”“星期一。”We're going away in a few days/in a few days' time .我们过几天就要离开了。It has snowed almost every day for the past week.过去的一周几乎每天都在下雪。
