This is the year 2070. Today is my (fifty) birthday, but I look like a person of eighty-five. I have serious kidney (肾脏) problems because I don't have enough water (drink). I'm afraid I don't have much time left to live. I'm already one of the oldest people in this society.
I remember when I (be) five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half hour. At that time, /'wɪmɪn/ all had beautiful hair. Now, we have to shave (剃光) our heads to keep them clean without the use of water.
I remember there were "Saving Water" warnings in many public places, but nobody (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much (expensive) than gold and diamonds.
In the past, doctors suggested adults drink eight glasses of water a day. Nowadays, I am allowed half a glass only. Most people are weak and sick.
When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers how healthy people were. When he asks, "Why is there no clean water now?" I feel guilty (有罪的). I belong those people who simply turned a blind eye to all the warnings.
I hope the people living in the 2020s (true) understand the importance of saving water.
