Jack is a little schoolboy. He lives in a small town in England. His father works in a factory in London. One day his mother 1 him to post a letter to his father. Jack walked down the street. He didn’t see a letter box on the street. But he really 2 a basket with a sign on it. The sign said, “PUT LITTER IN THIS BASKET”. “I can read,” thought Jack, but he couldn’t 3 the word “letter” right. Jack dropped the letter in the basket. Then he ran 4 to tell his mother about the basket. “Oh, no, child!” said his mother, “You put the letter in a basket. That litter basket is 5 old paper and other useless things.” “Oh,”said Jack,“does the 6 on the basket mean that?” “Yes, it does,”said his mother,“The word is‘litter’not‘letter’. Now get the letter and post it.” When Jack got there, a man was putting the old 7 in a truck. “Stop!”shouted Jack, and he began to tell the man about the letter. The man helped him to look for the letter. After a while they 8 it. Then Jack put the 9 in the letter box. He said,“ 10 don’t they tell us all the words when we first go to school?
