next 和the next的区别
next+以现在为标准的时间-即当谈到紧接着眼前这一周这一月这一年的下一周下一月下一年.
eg:I shall have been in thee army for fully three years by July next year.
the next+以过去或将来为标准的时间-即当谈到紧接过去或将来的某一周某一月某一年的下一周下一月下一年.
eg:The forign guests spend the first week in Beijing and the next week in Shanghai.
还有一点,
next+时间名词－前不可加任何介词
the next +时间名词－前可用适当介词（也可省略）
next用于一般将来时
例如：I will go to the park next day.
the next用于过去将来时
例如：I would go to the park the next day.THE NEXT DAY应该用于过去将来时..
NEXT DAY一般将来时.
THE FOLLOWING DAY用于两种时态.one day和some day在表示将来的某一天时,意思一样,但some day不能表示过去的某一天one day“某一天,有一天”既可用于一般过去时,也可用于一般将来时
