Jack was standing on the steps of a house. He was playing. A postman came to him. He asked Jack, " Are
your parents in? " " Yes, my mother is cooking, my father is watching TV," answered Jack. The man began
to ring the bell. He rang and rang, but there was no answer. At last, he turned back to Jack and said angrily
(生气的), " You told (说) a lie (谎)." " No! what I said was right. But this is not my home." answered Jack.
