It's well known that a lion of a man has a brave heart.He is considered to manage anything,although everything goes not like a bird.So he has been having a whale of a time.
So does the bee's knees who keeps laborious everywhere.

But it is another business for an odd fish.May be he like running in the dog days.Or he will keep being quiet as a mouse in the hot debate.
Therefore we must learn to be a lion of a man or bee's knees .Just as we learn english,we should have a strong will,and the never-surrender spirit.(by eric, rita ,violet,and Toily)
