例如在过去时态中is 要不要换成was.

这是个固定句型,记住前后搭配的时态即可
It is/ has been 时间段since 句子(一般过去时)

It was 时间段since 句子(过去完成时)
例如:It is 2 years since I visited Beijing last time.
It was 2 years since I had visited Beijing .

要的.

it is time+时间段后接什么时态？ It is +时间段 +since... 中的 is 有没有时态的变化翻译CS1.5；1.6主题曲：It's My Life；She Is My Sin 。 she is my sin吉他谱 she is my sin 纯音乐 shi is my sin 歌词 It's+时间段+since+主语+? it is me 还是 it is I what it is?/what is it? it is 和is it 怎么用？
