it is ```that ```,后面的动词用什么形式啊 逗号在这里连接的是什么

it is/was ...that 是强调句,可以强调除了表语以外的其他句子成分 比如
I met Li Ming at the railway station yesterday.
强调主语：It was I that (who) met Li Ming at the railway station yesterday.
强调宾语：It was Li Ming that I met at the railway station yesterday.
强调地点状语：It was at the railway station that I met Li Ming yesterday.
强调时间状语：It was yesterday that I met Li Ming at the railway station.
强调原因状语 It is because he is ill that he can’t come.
强调宾语补足语 It was chairman that they elected him.
但是不能说 It is beautiful she is.因为beautiful在句中作表语的
可以用she is beautiful 以及 感叹句来强调
how beatiful she is!
一般一个强调句 就这么结束了 没有见过后面有逗号 再加别的成分的句子
帮你分析下 你的句子
动词的时态根据句子本来的时态而定
再问： 我是在六级的听力里面看到的啊 它用的是动词的原形啦
再答： 也许后面是个从句 或者是个句号 另外开始了一句 都指不定
