Early rising is helpful in more than one way.We all need fresh air.But air is never so fresh as early in the morning.Besides,it is useful to do morning exercises.
Secondly,early rising can give a plan to our work for the day.We can not work well without a good plan.
Thirdly,early rising gives US enough time to get ready for our work,such as to wash our hands and faces and eat our breakfast.
Late risers may find it very difficult to form(形成)the habit of early rising.They have to make an effort(努力)to do so.As the English proverb says,"Early to bed and early to rise makes a man healthy,wealthy and wise."
