Let's compare transport today and in the past. / In the past, people walked or rode horses, so journeys were slow. The trip from Beijing to Shanghai took weeks! Today, the high-speed train can do it in about four and a half hours. It is much faster and safer. Planes can take us even farther—as far as the other side of the world in one day. / However, things are not all good. Cars make the air worse than before, and the traffic in big cities is bad, especially in the morning. Some roads are as busy as markets. / What should we do? Scientists are working on clean energy cars. They will be as fast as today's cars, but much cleaner.

Students in Class 3 had a hot debate（辩论）about it last Friday. / Team A said the smartphone is one of the best inventions. “It brings people closer. I can video-call my grandma in another city every day. Shopping, studying and finding information are all easier with it.” / Team B did not agree. “For some people, it is the worst invention,” they said. “They play games all night, so they feel much worse the next day. Some people even look at their phones at dinner, and family talks become fewer.” / Then their teacher, Mr Wu, asked a question: “Is the phone good or bad?” The class became quiet. Soon Lily said, “The phone itself is neither good nor bad. It depends on how we use it.” Mr Wu smiled and said that was the best answer of the day. / Inventions are like tools.
