Smile is very important in our lives. We often see Mother's smile. Mother's smile is  (like)a spring wind and lets us feel warm in  (we)hearts. When you are sad, it can make you  (happily)again；when you fail, it can help you  (cheer)up and work hard again. When you give up, it can help you try your  (good)again and so on.

    Smile is very easy,   it is very useful. So let's learn to smile. Everyone (need) others' smile. When we give  (other)a smile, we will feel happy, too. And maybe next time, when you smile, the other people will give a smile to you as well.

    My friends, let's learn to smile as often as possible. It is like  sun. Life with smiles will be  (fill)of sunshine.
