I think it will be very different from today, and in many ways, it will be better. First, there will be smart robots everywhere. They will help us clean the house, cook delicious meals and even look after children. Second, students won't need to carry heavy schoolbags. They will study online using VR technology. There will be fewer cars in the streets because most people will use flying taxis. As a result, there will be less pollution and the air will be much cleaner. However, life may become faster, so we will have less free time to relax. I believe the future will be amazing as long as we use technology wisely. If we work hard and protect our planet now, our dreams for tomorrow will surely come true. 学科网（北京）股份有限公司 $
