dloveto Certainly Ofcourse 等来回答 若不接受 常用Sorry等来有礼貌地拒绝 一般情况下需要说明不能接受邀请的原因以表示歉意 Canyoucometomybirthdaypartytomorrow 明天你来参加我的生日聚会 好吗 Sorry Ican t Iamgoingtovisitmygrandpa 很抱歉 我来不了 我要去看我爷爷 1 can may都可表示 许可 may用于较正式 客气的场合 而can比较随便 口语 Youmay cansmokehere Borrowersmaynottakeoutofthelibrarymorethantwobooksatatime Thepolicemansaysyoucan tparkhere 2 May CanI we 表示征询对方许可 Canyou 表示请求 MayIuseyourphone Yes youmay
