A time and a place in the past I am someone who enjoys dreaming and always imagines that I have the capacity of going back to anytime and anyplace as I like If I were equipped with such a skill, I would dated back six hundred years and go to the areas around the Yellow River My concerns which influence the decision are presented as follows The first and foremost reason is that I am worried about the environment there and am eager to change the situation As we all know, there would not have been so many floods and such large deserts if the people haven`t over reclaimed this area in the past Therefore, if my dream came true, I would describe the awful environment to the people at that time, and suggest them against unwise reclamation At the mean time, I could teach them useful science and technology, which will enable them to live an even better life without the expense of destroying the environment Another reason for my choice is that about six hundred years ago, the areas around the Yellow River so prosperous that I can have many wonderful experiences there I can shopping in the ancient stores, learn KongFu from real masters, and take part in all kinds of their daily activities What a nice experience it would be! In addition, as far as I know, the language used there at that time are quite the same as what we use now, which means I would not have trouble in communicating with others if I could go back there Otherwise, I will not have a happy life their In a word, I really hope that I could go back to the area around the Yellow River at about six hundred years ago
