I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular.Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.
最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。
