综合写作第一段中的内容

The lecture talks about a much more closely research about meercat and people’s activity about altruism. The speaker says that the theory in the passage was
            very different when compared to what happened for real .

这个地方that从句中是应该用过去时么？

多谢各位！！！

OK, IT'S GRAMMATICALLY CORRECT
