英语肯定陈述句变否定句的规则是: 句子中有am, is, are 或was, were的时候在这些词后面加 not.比如He is a student.变成否定句就是He isn't a student. They are friends.变成否定句就是They aren't friends.
如果肯定陈述句中有情态动词can,must或助动词will. fave, has 等,在这些词后面加not例如I can sing.变成否定句I can't sing. He has been to Shanghai变成否定句He hasn't been to Shanghai.
如果肯定陈述句中没有这些词要变否定句就需要加助动词do,does或did.比如Iplay basketball否定句就是I don't play basketball. 所以She flies a kite变成否定句就是She doesn't fly a kite.
she flies a kite改为否定句
问题中所给的句子是一个主语为单数第三人称一般现在时的陈述句,而且是肯定形式。句子意思是她放风筝。要把它改成否定句,需要在动词前面加否定词doesn't,动词恢复原型,其他成份不变。所以原句的否定句就是She doesn't fly a kite.她不放风筝。
