Question

Ann like her new shoes,变为一般疑问句？

Answer 1

这句话是一般现在时，如果改为一般疑问句就是Does Ann like her new shoes？

Answer 2

需要提醒一下，Ann like her new shoes.中的like 应该改为likes,因为Ann是第三人称单数，这里的谓语动词要用三单的形式likes。

改为一般疑问句为：
Does Ann like her new shoes?

Answer 3

改为一般疑问句为Does Ann like her new shoes？
另原句中应为likes

Answer 4

这类练习在句子前加助动词就可以了
助动词形式随主语变化，主语第三人称单数用does 其他用do，实义动词恢复原形
Does Ann like her new shoes？

Answer 5

助动词引导，三人称单数，主谓依旧即可。
Does Ann like her new shoes？
