【答案】
Should old buildings give way to the new ones? Different people have different ideas.
I think old buildings should be protected instead of being knocked down.
The old buildings usually represent the local history and culture. They carry the
memories of our elders, so they mean a lot to the local people. Enjoying the old buildings is
like travelling to the past. It helps people explore history. Also, old buildings help attract
tourists. They are not only home to the local people, but also works of art. Tourists can
know a lot about the local culture and history. And local people can live a better life with
more and more tourists.
I think our government should protect old buildings because they are great treasure.
Before knocking down an old building, we should think twice.
