”我第一次见贺军翔是如此开心“可翻译为：I was so happy for it was the first time that I had met He Junxiang. 句型分解：1、句中的for是“由于”的意思。2、it was the first time that I had met He Junxiang是“I was so happy”的原因，是一个完整的句型。3、由于it was the first time中的谓语动词用的是过去时态（与I was so happy过去时态对应），所以后面的meet用过去分词形式，即had met。固定用法拓展：it is/will be/was the first / second time ＋ that+clause当主句谓语动词用is/will be 时，从句用现在完成时。当主句谓语动词用was时，从句用过去完成时。eg: It will be the second time that I've met him. 这将是我第二次遇见他。eg: It was the first time this year that he hadn't attended the class meeting.这是他今年第一次缺席班会。
