Step 2 Presentation and Practise (完成任务，操练新知)
Ask one student to read the background of the storybook on Page 1 for the whole class. Then students get to know the names of seven little dwarfs and understand they should help Snow White find out the naughty dwarf who breaks social rules by finishing different tasks.

asking “What does the dwarf do?”.
