On August 30, the Chinese government announced that kids would no longer be allowed to play games Mondays to Thursdays. Should a government be responsible for limiting how much time kids can online? Here’s what four of you say.

Some children need more screen time than others. Some children need to use screens for homework. Government limits would not be fair to people who are responsible with their screen time.

Most people spend too much time on their phones and TVs. You can hurt your eyes and waste your time. And watching a lot of TV or playing games can influence kids’ learning and social skills. It’s bad for their future.

The government should not limit screen time. First, kids should have as much time on screens as they want. Second, kids should have the right to talk with friends online and play their favorite games. Third, screens help kids develop their knowledge.

The government should set screen-time limits, because kids can forget how to communicate with others. They can forget to take care of themselves. What’s more, kids can sometimes stay up too late. Not getting enough sleep can make you feel tired and affect your performance in school.

Once upon a time, there was a queen who lived in the palace. She wore silk clothes, ate fine meals, and had many servants but she felt unhappy.

“How can I learn the secret of happiness?” The queen said.

“The beautiful moon and stars make me happy!” said one of her servants.

The queen just said, “I get angry for I cannot take them!”

“What about music?” asked another.

The queen answered, “It sounds nice-but fades into the air and gone!”

The next day, the queen went to the market. Suddenly, she saw a woman carrying a lot of firewood and leading some goats. She wore an old red coat, but had a wide smile on her face.

“That woman seems to be truly happy! It must be her magic coat!” The queen went up to the woman. “I will give you a piece of gold for your red coat!” she said. When she put the coat on and soon realized that she did not feel any different.

“It must be the woman’s firewood!” So the queen went back to the woman and bought the firewood for two pieces of gold. She proudly lifted the firewood, but the firewood did not make her happy.

Surely, it must be the goats? The queen went over to the woman. “I must have your goats! I will give you three pieces of gold!” Then she set off for her palace with the red coat, the firewood, and the goats.

“What a wonderful day!” the lady thought to herself. “The sun is warm, the wind is cool. And best of all, the queen has given me so many pieces of gold. Things just keep getting better and better!”

①It is 9 a.m., and 14-year-old Noah and his family are about to leave their summer house near Halmstad in Sweden. But before they go, they must sort out the rubbish and empty boxes for recycling. This has become a habit. “There is always a place where I can recycle my rubbish,” says Noah. Sweden produces around 4.4 million tons of waste a year. When it comes to waste management, Sweden has done a good job.

②When children are at young age, schools encourage them to do activities that make recycling a part of daily life.In the southern city of Helsingborg, pleasant music is played in public waste bins to make recycling more enjoyable. There is even a national day to recycling.

③The country also rewards those who recycle. In 1984, Sweden started the Panta System. It encouraged people to recycle their aluminum cans (铝罐) and plastic bottles for money. The process is very simple. People put their items into a machine. Each piece has a small bar-code (条形码) that tells the machine how much it is. The bar-code is read, and the value is added to the total amount. People can get the money by pressing a green button, or they can give the money to charity by pressing a yellow button. In 2021, the Swedish recycled 1.8 billion bottles and cans using panta.

④Everyone gets involved in recycling. Swedes wash and sort their rubbish at home. The government has made recycling easily by placing recycling stations no more than 300 meters from homes, schools, and offices. Plastic, paper, metal and glass items have different boxes. Each box is a different color, and its holes are in different shapes to make sorting simpler.

Temperatures can drop to -225℉ on Mars(火星)，and the air is unbreathable. But around 4 billion years ago, the planet had oceans and seas, and thick air. These conditions could have supported life.

For the past nine and half years, NASA’s Curiosity spaceship has been exploring the planet’s Gale Crater, which was probably once a lake. Curiosity has studied it to find whether tiny life-forms called microbes ever lived there. They could have left chemical signs on the surface. In January, NASA announced that Curiosity might have found what it was looking for.

In a newly published study, scientists have found carbon 12. It is a chemical which is connected with life on Earth.

The scientists give a possible explanation. Long ago, microbes grew on Mars. Those microbes died and produced methane (甲烷) gas. The gas rose into the air, and was broken down into carbon by sunlight. The carbon rained down and dropped on the planet in dust.

Christopher House was the lead scientist on the study. He says Mars may have life as Earth once did. “The Mars rocks are similar to Earth rocks from Australia from 2.7 billion years ago,” he says, “When our air was rich in biological methane.”

______▲______. There are still other ways to explain the carbon on Mars, Paul Mahaffy is a retired member of the Curiosity science team. “We would really need more information to say we’ve similar life.” he says.

Another explanation for the carbon is a change of air on Mars. Energy from the sun could have produced the carbon. It is also possible that a lot of cloud which is full of carbon passed through the solar system (太阳系) and left some behind. Scientists are waiting until Curiosity gets more findings. “All three of the answers fit the information that we have,” House says. “We are told to take our explanations seriously, but that is the right way when studying another world, such as Mars.”

A basketball game is played for a set length of time. A clock runs while the game is played. It stops whenever play stops, such as when a player breaks a rule. The referee (裁判) pulls down his arm to show that the clock is starting

The referee puts his hands on his shoulders to show that one team has asked to stop the game for 30 seconds. The team might want to discuss a game plan or just take a break.

The referee makes a T shape with his arms if a player is rude for a bad sport-especially when the player is rude to him

Touching the ball with your leg or foot is no-no in basketball. If you do, the referee kicks his foot.
