1 次の英文は, ある新聞の投稿欄に掲載されたものである。 英文を読んで, あとの問いに答 えなさい。 (福 井) We have a lot of problems around us. When the problems are too big, we think we can't solve them. But if we look at the problems from a different view, we can sometimes find the answers. I will tell you about Mexico City. It is not as large as Tokyo, but it has more people than Tokyo. It is ina high place and it has only one big river. So it is difficult to get enough water. About 160 years ago, many people began to use water under the ground. Do you know what happened after a lot of people used too much water under the ground? Yes. The ground went down very much. That was a big problem. Then people in Mexico City looked at this problem from a different view. Some people thought, “How about using the place that went down?”、Other people thought, “Can we use the water we have already used again?” They put the water into the place. Soon it became a kind of lake. People made the water clean and used it again. We have an example in Japan, too. In big cities it is especially hot in summer. There are many reasons, and we know one of them. There are not so many trees in the big cities., If there are many trees, they can give us some shade in many places and the températúre around us will go down. But the big cities have few places for trees because they have a lot of huildinos Some penle thouoht about the problem hard TThen thev 1aorod ota building
