all there's left to do is run .能不能给我讲一讲这个句子为什么这么用,有什么语法么? All there's left to do is run这句子是什么结构 All there's left to do is run.that is all there is to it.这两句 all there left to do is run 符合语法么,left在这里是分词做定语? I'll be waiting,all there's left do is run.的中文意思 I'll be waiting all there left to do is run 帮忙分析一下这个句子的语法结构吧that is all there is to it my dream is to be a teacher.我觉得这个句子乖乖的 有什么语法在里面呢?为什么is加to be there is only one team left 为什么用left（语法要点?） it sure is为什么这么写?有什么语法吗? 请问这个句子中all I have to do is learn english.is跟learn不是都是动词吗?为什么 there is little time left为什么用left 不能用to leave
