One day Mother looks at Simon's shoes and says, “L   at your shoes. They are very dirty（脏）. You must c   them.” “ But I cleaned them yesterday,” says the boy. “They are dirty now. You m   clean them now.” “I don't want to clean them t   . If I clean the pair of shoes today, t  will still be dirty tomorrow.” “All right. D   do it then.” Simon's mother says.
In the evening, he is very h   . He asks his mother to give him s  to eat. “You had breakfast in the morning, Simon, and you had l  at school.” His mother says. “But I’m hungry a     .” “But if I give you something to eat today, you will be hungry again tomorrow.”
