正确：Can you sing or dance?正确：Can you play chess?错误：Then you can be in our school art festival.改成：Then you can be in our school on the art festival.不明白的再问哟!请记得采纳,多谢!...我的七下英语书上第6页上写的是 Can you sing and dance?sing and dance当做一个并列关系的谓语动词。Can you sing and dance意思是“你会唱歌跳舞吗”。Can you sing or dance? 你会唱歌还是会跳舞？
