"What will you be in the future? "Mrs White asks the students in her class. And here are three of the students ‘answers.

Nick: I love playing computer games. I will be an e-sports(电子竞技) player, My parents don't think it's a good job, but 1 like it.

Elsa: I will be a traffic policewoman and work in the sky. There will be lots of small planes in the future. It will be cool to work by plane. 

Ben: I will be a football player. I will play in the national football team and win the World Cup with other players. It's not easy, so I must practise hard now. 

About 1 in every 160 children has autism（自闭症）. Lots of people are working hard to help those children. And luckily, there are also robots helping them. 

Catherine, a Hong Kong professor, has developed an educational programme. It uses role-playing robots. The programme, Robot for Autism Behavioral Intervention（RABI), is for children with autism between the ages of 3 and 18. Its purpose is to help them be more social（社会的）. According to Catherine, more than 1, 200 children have taken part in the programme since it was started in2015.

As we know, it is tough for people with autism to communicate with others. Others can't understand what they want to say easily. So they feel worried or nervous about half of the time. The robots teach them social skills to make them less nervous. In a typical class, two small robots act out social conversations on a table. It helps the children see the difference between proper and unacceptable behavior. After that, the daughter has been in the programme for seven months. Her social and communicative skills have improved a lot. 

More than 20 non-profit（非盈利的）groups and public schools in Hong Kong and Macao have joined the programme and helped develop it. Catherine hopes the programme can help more children with autism. 

When people talk about air pollution, they usually think of smog, acid rain (酸性雨), and other forms (形式) of outdoor air pollution. But did you know that air pollution also is inside homes, offices, hotels and other buildings？Indoor air pollution is more serious. The air in your home can be 2 to 100 times (倍数) more polluted than the air outdoors！In fact, some American doctors say that 50% of illnesses have something to do with polluted indoor air. Indoor air pollution is bad for our health in many ways. Young children and the old often suffer(遭受) more from air pollution. People with health problems may also suffer more when the air is polluted. Indoor air pollution can be bad for people's eyes, nose and throat. Air pollution, both indoor and outdoor, can also lead to cancer, heart disease, and even bad for the brain！In the great London fog in 1952, 4, 000 people died in a few days because of air pollution！It is said that half a million young kids and women die each year in India because of indoor air pollution！

There're many ways to reduce (减少) indoor air pollution. Here are some of them and see if they can help you：

★Increase outdoor air coming indoors and open your windows for 15 to 30 minutes each day.

★Turn off all the lights and fans when you don't need them.

★Share your room with others when the air conditioner is running.

★Don't smoke and try to stop your family members from smoking. People who smoke are going to have trouble breathing and even die someday. If you're smart, don't ever start.

★Environment-friendly products, such as water-based paints pollute less and work well.

To improve children's fitness, Freestyle 360 has introduced some fun fitness classes for children between nine and thirteen years old. We want to encourage children to turn energy into sports and have social fun in a caring and professional environment.
