The officer made the remarks while addressing a video conference,    2    is a part of the Stockholm+50 international meeting in early June in honor of the 50th anniversary of the Stockholm Declaration.

China has put environmental protection high    3    the agenda since 1972 and made notable progress in resources conservation, sustainable development and international governance.

China is a world leader in using renewable energy resources, with installed capacity of hydropower, wind power, photovoltaic (光伏) power and other non-fossil energy    4    (reach) 1.1 billion kilowatts. It is also one of the fastest    5    (country) worldwide to reduce energy consumption intensity.

He also underlined continuous improvements in China's ecological environment. In 2021,    6    average concentration of PM 2.5 in cities decreased by 34.8 percent from 2015, while the surface water with good quality and forest coverage rate reached 84.9 percent and 23.04 percent    7    (respective), the officer said.

So far, China    8    (revise) dozens of reform plans related to ecological and environmental protection and revised over 30 laws and regulations.

This is the year 2070. Today is my    1     (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     2     (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     3     (be) five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half     4     hour. At that time,     5    (woman) 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     6     (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much     7     (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     8     how healthy people were. When he asks, “Why is there no clean water now?” I feel guilty (有罪的). I belong     9     those people who simply turned a blind eye to all the warnings.

I hope the people living in the 2020s     10     (true) understand the importance of saving water.
