请问下面的英语有木有错误（七下知识） Can you sing or dance?Can you p

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!======以下答案可供参考======供参考答案1:应该没有吧，can 没有人称和数的变化，一般现在时态后接原型。供参考答案2: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.供参考答案3:正确：“Can you sing or dance?” 情态动词“can”后面加动词原形；正确：“Can you play chess?”；错误：“Then you can be in our school art festival.”根据句义，时间状语“art festival”前面应该有个介词“on”连接，“festival”虽然是可数名词，但若前面有“art”来修饰便可以不加冠词“the”等等；正确的应该为“Then you can be in our school on art festival.”

对的，就是这个意思
