Hasn't he slept for 20 hours?和Hasn't he been sleeping for 20 hours 哪个是对的?有什么区别?表达的意思是一样的吗?

都对表达的意思也基本一样
只不过前者强调从睡觉发生到现在已经20小时后者强调一直睡了 20个小时
都是现在还在睡
再如我学英语三年了i have studied english for three years
三年来我一直学英语i have been studying english for three years
再问：这两个是问句啊应该表达的是20个小时没有睡觉了吧不是睡了20个小时吧谢谢
再答：这是否定疑问句也叫修辞疑问句不表示疑问而表示强烈的肯定难道他没有睡觉睡20小时？
