　　One evening, Alan, one of his classmates, came to his home 　2　 an exercise book in his hand Alan live in a house not far from John's. They often go to school 　3　.

　　“Would you help me with this maths problem?” Alan said as soon as he came into the room. “It's too 　4　 for me and I can't work it out.”

　　“Let me try,” John said. “I 　5　 it isn't too hard for me.”

　　John tried his best but he couldn't work it out, either.

　　“If we had a computer, all the problems would be 　6　 for us to do.” Alan said.

　　“A computer…” John thought for a minute, then he said, “I've got an idea, We can buy one in a shop!”

　　“A computer is very expensive, and we don't have enough money.”

　　“That's OK.” said John. “We can ask the new president 　7　 some money. He said he would help anyone in 　8　. I'm sure he will help us. He is very rich, you know.”

　　So they decided to write a letter to the new president. Soon the letter was finished and they hurried to the post office.

　　In front of the post office stood a small box. They dropped the letter into the box carefully and went home 　9　.

　　The next morning, when they passed the post office on their 　10　 to school. They found, to their surprise, the box was not a post-box but trash-box.
