this is my first time that 后面是用什么时态，有人有一般时也有人用现在完成时的，究竟是哪种？帮我一下。谢谢

Answer 1

那得看你后面要跟的动作是什么性质的，是需要用完成时强调的，还是已经做过需要用过去式的。This is my first time to contact you.这是我第一次和你们联系。This is the first time that we compete in the World Championship.这是我们第一次参加世界绵标赛。This is the first time that I have ever been abroad.这真是我第一次出国。This is the first time that China proposed a FTA initiative.这是中国首次提出自贸区建设构想。This is my first time came to China, first came to Guangzhou.“这是我第一次来到中国，第一次来到广州。”This is my first time that I fell into a unconsciousness.这是第一次休克。

应该用现在完成时。因为this is my first time that 是指【有生以来】第一次，是从过去到现在累积的总数，符合现在完成时的概念。

这个是要分什么场合的，就是时间和事件的先后关系，你可以看下面两句： it is the first time +现在完成时 ----------it is the first time that I have seen a tiger. it was the first time+过去完成时 -----------It was the first time that he had said ( that )he loved me
