It's long time since he left his English,____?[A] didn't he[B] hadn't he[C] wasn't it[D] isn't it我不知道是怎么判断的,这题应该是反意疑问句.但是我不明白的是这里.就是带从句的反意疑问句,那逗号后面的结尾

It's a long time since还是It has been a long time since it's a long time since i last saw you It's a long time since it raimed last time帮忙翻译下这句话, It's been a long time since I last saw a film.还是It's a long time since I last saw a film. it's a long time since i last saw you这句话有错误么 It's been a long time since I met you last 译成中文 It's a long time since we met last(改为同义句） It's a long time since they left.的同义句 求歌词：it s been a long time since we drank the arsenic It's a long time since you come to see me.错了什么? it's a long time 空格 we met last .a:before; b:since; 为什么? it's a long time since we met in our hometown改为感叹句 it's quite a long time since i _____（hear）from my cousin in America i think it's been a long time since i've heard anyone is good since在这里是什么用法? It's a long time since we met in our hometown.time 不是不可数名词吗,为什么还用a It’s a long time since we met last.(保持句意) We haven't seen each other____ ____ . it's a long time since we met lastWe haven't seen each other ( )( )【同义句转换、两个空 it's a long time since Hong Kong(come)back to China用come 的适当形式填空
