    In America, the school life is not easy for us students. There are so many rules we have to follow. When we start school, we get a rule book. There are always teachers looking out for people who are breaking the rules and prefects (长官) are everywhere too.

    The most rules are in the classroom and in the hallways. For example, you can't run or dance around in the hallways. We can't put our bags everywhere in the hallways.

    You can't eat or drink in the classroom or the hallways. Prefects watch you, They can give out duty slips (cleaning the dining hall for about 2 hours).

    If you make mistakes, you will get a detention. You may have to do some work for school. A detention is the most painful. You have to do a lot of tiring and boring things. There are rules for students out of school as well. Boys should not buy take away food in the street if they wear the school uniforms. The school also expects good behavior on public transport and in public places.

Future astronauts could travel with emotional support robots

    To help astronauts of the future survive (幸免于) the mental (精神的) challenges that come with staying in space for quite a long time, space travelers‟ tasks could soon be accompanied(陪伴) by AI-powered, empathetic (有同理心的, 同感的) robotic helpers.

    Not only does space travel present astronauts with lots of physical stresses, spending months or years in such a physically demanding (要求高的) place with limited space and the same people can also raise many mental tests as well. According to MIT Technology Review, scientists are working to alleviate astronauts from some of the latter challenges by creating "an AI assistant that's able to feel human emotion and respond (做出反应) with empathy."

    While such a technology would prove itself useful by being able to predict the needs of the

crew members in space and "intervene (干预) if their mental health is in danger," it has the potential to be life-saving when humans choose to explore beyond Earth's gravitational field (引力场) and towards deep space.

    Though astronauts currently on the International Space Station have an intelligent robot to interact with called CIMON, it is short of proper emotional intelligence according to NASA CTO Tom Soderstrom. As a result, a team at the organization's Jet Propulsion Laboratory is working on a more complex (复杂的) emotional support companion that can control a spacecraft's functioning in addition to tracking the crew members‟ behaviours.

    Right now in the lab, an AI-equipped robot called Henry the Helper can be found walking around the grounds assisting visitors who appear confused or lost based on their facial expression. Two more emotionally intelligent robots are expected to be introduced later this year, one of which is said to be able to take part in conversations more complex than giving navigation(导航) assistance.

    The team's final goal is to make a companion named Fiona the Future a reality, an emotionally intelligent cross-platform system. Fiona, if all goes according to the JPL's plans, will help keep astronauts of the future stay mentally fit as they start their journeys to deep space.

Breakdancing, also known as breaking, will be an Olympic sport for the first time in 2024. To attract younger people to watch sports games, breaking is becoming a new event at the 2024 Paris Olympic Games. Paris 2024 Olympics will see 16 b-boys and 16 b-girls compete in one-on-one “battles”. The top finishers will get the Olympic prize.

Breaking is a kind of street dance. It is also part of the hip hop movement. It grew up together with hip hop during the early 1970s. It was really popular among African American and Latin American young people.

In the past, people wouldn't believe that street dance could become an Olympic sport. However, it comes true now. When the International Olympic Committee says breakdancing will be added to the 2024 Paris Olympic Games, a lot of people are excited. “It is a historic time not only for b-boys and b-girls, but for all dancers around the world. We thank everyone who helped make it possible,” says Shawn Tay, president of the World DanceSport Federation (WDSF). WDSF is happy about the result and it will prepare for the breakdancing competition to make the event unforgettable.

Skateboarding, surfing and rock-climbing are also becoming the 2024 Paris Olympic events. In fact, the three new sports have already been added to the program for the 2021 Tokyo Olympics. These new sports are going to make Olympics more attractive.

After a relaxing weekend, children have to go back to school on Mondays. For parents, they should do something helpful (有帮助的) to let their children get to school on time.

Let children take a good shower. It's good for children to take a shower before they go to bed. It can not only help them sleep well but also save time next morning.

Ask children to go to bed early. School starts at 8：00 a.m. So please let your children go to bed before 9：30 p.m. Your children should (应该) sleep for about nine hours every day. This is quite important because they have to get up early next day.

Make a good breakfast for children. Breakfast can help children study better (更好的) in the day. It can help students listen to teachers carefully (细致地) and think well in class. Also, it's good for their health.

Getting to school on time is very important for your children. So please help them. If you can do the things above (以上), they will study and live happily.

Last summer I went to a park and saw a little dog walking around. He was dirty and weak. When he saw the bread in my hand. he ran up to me. He was so hungry. But he ran away as soon as he saw my mom. I felt sorry for the homeless(流浪的) dog.

From then on, I began to pay attention to homeless pets in Shanghai. There are more than 270,000 homeless pets in the city now and this number is still growing. The fast growth of homeless pets can cause many big problems, for example, they may spread diseases(疾病) and so on.

Why are there so many homeless pets? Some people leave their pets behind in the street when they don't want to keep them anymore, but the city can't provide enough animals' homes for the homeless animals.

How shall we work together to save these poor pets? Firstly, the government should pass laws(法律) to protect pets. Secondly, we can raise money to build more animals' homes. What's more, we could teach people how to take care of pets. Lastly, we can get a pet from the animals' homes instead of buying a new one.

I hope we can build a better world not only for homeless pets but also for ourselves.
