In an English class, the students all work hard at their lesson. Their English teacher is very happy. She sings some nice songs with them, and then she goes to the blackboard and writes “S-M-I-L-E-S” on it.
“This is the longest word in English.” She says to the class.
A girl stands up and says, “It has only six letters! Why do you call it the longest word in English?”
The teacher smiles and says, “ Because there is a mile(英里) between the first letter and the last letter.”
