一、“It/This/That+ is/will be + the first +time + (that) + 主语+ have/has done +其他”
二、“It/This/That+ was+ the first +time + (that) + 主语+ had done +其他”
例如：
（1） This is the first time that I have seen such an interesting film. 这是我第一次看如此有趣的电影。
（2） It was the last first that she had come to this mountain village to see the children. 这是她第一次来这个山村看孩子们。
（3）That will be the first time that she has got the prize. 这将是她第一次获奖。
扩展资料：
这是第几次做某事的英语句型：
“It/This/That+ is/was/will be + the first( second ,third...last) +time + (that) + 主语+动词的完成时+其他”
在此句型中，that可以省略; It可以换成This或That; first 可以换成Second或third或last等，以表达不同的意义。
特别注意，主句用现在或将来时态时，that从句中通常用现在完成时态；主句用过去时态时, that 从句中多用过去完成时
