when we feel stressed out ,we will go for a walk
we don't leave the classroom until after class
taking more exercises is good for our bodies
We will go out for a walk when(we are) stressed out. (we are是可以省去的)
We don`t go out of the classroom until class is over. 或者用倒装结构:Not until class is over do we go out of the classroom.
It`s good for us to do more exercises.
