Anne said,"That's cahnged since I was here."的间接引语

问题描述:

Anne said,"That's cahnged since I was here."的间接引语
Anne said,"That's changed since I was here."这句话变成间接引语是Anne said that that had changed since I had been thre 还是 Anne said that that had changed since I was there.原因是什么?

选第二句.
因为since+句子表示一段时间时,
since后用一般现在时.
此为固定用法
