英语中，从句与主句的时态一定一致吗？那“看！他就是昨天我在公园里看到的人！”这句话怎么表达？

不一定要一致。
He is the one that I saw in the park yesterday。
I didn't know where he lives here。
我说话前不知他住在这。现在知道他住在这。
I don't know where he lived last year。
我现在才知道他去年住在这。
明白了吧。我是从事英语的， 不明再问。

当然不一定一致了。
Look! He is the one that I saw in the park yesterday!

是的。Look,he was the man I saw yesterday.

是：I didn't know where he lives 我原来不知道他在哪生活

look! he is the man i saw in the park yesterday!

不一定的，
是要分开的
