Question

that is a city where you can see green trees everywhere.

那that is a city that can see green trees everywhere,也对吗

Answer 1

That is a city where you can see green trees everywhere.正确。
That is a city that can see green trees everywhere,正确。
因为【关系代词that】指代【先行词city】，【city城市】发出【动作see】是一种【拟人修饰手法】。
