现在完成时态的疑问句:Have /has+ 主语+动词的过去分词+...
现在完成事时态的肯定句式:主语+have/has+动词的过去分词+...
例如:1.She has finished her homework.
Has she finished her homework?
过去完成时态和现在完成时态的句式结构类似,只需把助动词have/has换成had即可.
例如;The film had been on when we arrived there.
Had she cleaned the room when you got home yesterday?
这两中时态的特殊疑问句式也类似.就是在他们的一般疑问句的基础上加上适当的特殊疑问词.
例如:What has she said to you
What had they brought to us when they came yesterday?
现在完成事时态的肯定句式:主语+have/has+动词的过去分词+...
例如:1.She has finished her homework.
