We all know and love the black mouse with two large round ears—Mickey Mouse. Over 80 years ago, he first appeared in the cartoon Steamboat Willie. When this cartoon came out in New York on November 18, 1928, it was the first cartoon with sound and music. The man behind Mickey was Walt Disney. He became very rich and successful. In the 1930s, he made 87 cartoons with Mickey. Some people might ask how this cartoon animal became so popular. One of the main reasons is that Mickey was like a common man, but he always tried to face any danger. In his early films, Mickey was unlucky and had many problems such as losing his house or girlfriend, Minnie. However, he was always ready to try his best. People went to the cinema to see the "little man" win. Most of them wanted to be like Mickey.教学片段：Step 1 Pre-readingBrainstorming:T: Do you like to watch cartoons?
