some day 和in the future能不能一起用？
day 和in the future能不能一起用？
应该不能一起用，因为 some day本身的意思就是:在将来的某一天,常用于一般将来时态。
例如I hope I will travel to the moon some day.
我希望将来有一天到月球上去旅行。
in the future的意思是:在将来，在未来。
例如
It is important for children in the future.
someday连着写和分开写的区别？
someday 意为有一天,多指将来的一天.在这一点上,somedaysome day.就是说上面的例子完全可以换成 day原意“若干天”,引申义来日(将来的某一天),或总有一天.常用于将来时,如:Some day my prince will come 总有一天我的王子会出现 Some day Ill find my love 总有一天我会找到真爱.基本上两者可以通用,除了some day可以拆开用,如:There is still some day before he comes.离他来还有些日子
