Environmental protection is one of the hottest topics nowadays. It was also something that ancient Chinese paid great attention to. In fact, the world's earliest environmental protection idea, ministry （部门） and law were all born in China. How did the ancient Chinese protect the environment?

The world's earliest idea of "managing state affairs（政事）through environmental protection"

Xunzi, a famous thinker in the Warring States Period, came up with the idea of "managing state affairs through environmental protection". He wrote in his book that vegetation（植被）should be protected well by humans.

Guan Zhong, a government officer 400 years ahead of Xunzi, was also an environmental protection expert. He said "a king who cannot protect his vegetation is not doing a good job".

The world's earliest environmental protection ministry"

Nine ministries set up by Shim, an ancient Chinese emperor, included "Yu"（虞） , an environmental protection ministry. Hie first " Yu'' leader was Boyi, an environmental protection expert. He invented wells so people could drink clean water. He knew a lot about animals and also called for animal protection.

The world's earliest "environmental protection law"

Over 4, 000 years ago, Dayu, an ancient Chinese water-control expert and also an emperor, made a rule, not allowing people to cut down trees in March or catch fish in June, because it was the time when they grew quickly.

Almost 3,000 years ago, Tianlv, the first environmental protection law, appeared in Qin. It recorded many ancient environmental protection rules. Two of them were interesting: firstly, rivers should not be blocked（堵塞）; secondly, grass and trees should not be burned to be fertilizer （肥料）except for summer. The second one is inspiring even for today. It can help to keep air clean and fresh.

Mum and I wanted to do something exciting during the summer vacation, so she 1  that we take the train to Grandma's house. Grandma lived far from our 2 , so we would spend one day and one night on the 3  just getting there.

On the day of our trip, Mum and I went to the train station. The train 4  and we got on. It seemed 5  and cool inside, compared to the bright, warm day outside. The conductor(检票员) took our 6  and showed us to the car(车厢) which we would ride in. Soon the train pulled away from the station. Outside the windows, the town buildings 7  gave way to the countryside. From time to time, children who lived near the tracks(轨道) would run out to wave 8  we passed.

At lunchtime, Mum and I had our meals in the dining car. There were different kinds of foods. It was9  being in a restaurant on wheels(轮子)! At bedtime, we went to our sleeping compartment. There were four beds in the compartment. My bed was above my mum's. I had to 10  into bed. The moving of the train made it  11  for me to sleep. I fell asleep soon.

When 12 came, we were near the countryside where Grandma lived. Mum and I quickly dressed and 13  our things. As the train slowed to a stop, we saw Grandma waving at 14  . Spending the week with Grandma would be wonderful, 15  I was already looking forward to the train ride back home.

Hello, I'm Anna Green. Sally is my 1 and John is my uncle. My cousin David is their son. My aunt is very 2 . Her things are always in the right3 . But my uncle and David aren't tidy. My uncle4 playing computer games. It's great 5 for him. His computer games are everywhere in the study(书房).In David's room, you can also see his 6 everywhere.

My aunt always 7 David put away (收拾)his things. 8 my uncle never(从不) does that. David can't find his things and always asks,"9 are my keys? Where's my bottle?" My uncle always says, "I don't10 . Ask your mother for help. She puts away your things, so 11 knows where they are."

One day, my uncle plays 12 games in the study. David 13 a map. He can't find his school on the map. He asks my uncle, "Where's my 14 ?"My uncle says, "I don't know. Go to 15 your mother. She puts it away."

 Chinese writer Hai Ya's The Space-Time Painter won the Hugo Award for Best Novelette(中短篇小说) on Oct. 21st. He became the third Chinese writer to win a Hugo Award after Liu Cixin and Hao Jingfang.

 When creating The Space-Time Painter, Hai Ya drew his idea from a famous painting, A Panorama of Rivers and Mountains(《千里江山图》). It was created by Wang Ximeng from the Song Dynasty. Based on Wang, Hai created a painter named Zhao Ximeng. After many hard times, Zhao's mind leaves his body and enters a space where a modern policeman is trying to solve a case(案件)about an ancient painting.

 Hai Ya's story with science fiction began in his childhood. "When I was a child, the bookstore in my hometown helped create a beautiful garden in my mind that belonged to me only. In it, science fiction offered the most beautiful‘flowers'; it opened a new world for me as a kid," Hai Ya told Beijing Youth Daily.

 Hai Ya's works feature a mix of history and science fiction. These two styles seem opposite: One looks back at the past, and the other faces the future. However, in Hai Ya's works, they find a perfect balance(平衡).

"If we can only imagine the future and things in space like rockets, it will only limit (限制) our imagination," Hai Ya told Shenzhen Special Zone Daily. "I don't think history is something completely in the past. It is flowing(流动的), and we can make predictions(预言) about the future by looking back at history.▲ ," he added.

 More Chinese writers today are trying to mix traditional culture with modern stories. Hai Ya believes that it is not a choice but a natural process." Our history and culture have universal values(普世价值) that can touch everyone," he said to Xinhua.
