1.How long (did) you (sleep) last night?For about 5 hours.I (feel)so tired now.
2.how are you feeling now i 'm feeling much better than yesterday.请问这两个句子都有现在感觉怎么样?为什么第1句用现在时I (feel)so tired now.,第2句却用了正在进行时 i 'm feeling much better than yesterday?另much better 能不能换成more better?last night能不能换成yesterday evening?三个问哦,
