新目标八年级下册Unit5作文:If I don`t have class tomorrow

If you don't live in tomorrow today,you will live in yesterday tomorrow!
We all should always keep our future in mind,or become future-oriented,make plans for our future,make efforts for tomorrow,make preparations for things to come,and we will of course achieve a lot.
Otherwise,we will have achieved little when we get old when it is too late to get started with anything.Then the only thing we can do is to look back or live in our memories of the old days.
