Would you like to live in a city where buildings turn the lights off for you, and self-driving cars will find the nearest parking space themselves?Although it might sound a little far from you, living in a"smart" city like this could happen sooner than you think.
Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a"telepresence" system (远程遥控系统)- allowing users to control the heating and locks, take part in video meetings, and receive education, healthcare and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.
The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.
About 75% of the world's population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. "Making cities smarter is one way out, and I think this will in turn make cities greener, " said Dan Hill, head of a research company.
There was a young man who was in trouble. He went bankrupt(破产)and his wife went away from him. From then on, failure was all that he had seen. Struggling(斗争)with this, he went into the forest alone. There, he met an old man who had lived there for a long time. He shared his story with the old man and asked, "Can you give me one good reason not to give up?"
"Look, "the old man said, "Do you see that fern(蕨类植物)and bamboo there?"
"Yes. "the man answered.
"When I planted the fern and bamboo seeds(种子), I watered them carefully. Within a few days, the fern quickly grew from the land, "the old man went on.
"However, I watered the bamboo seed for years, it still didn't sprout. But I didn't give up and continued looking after it. In the fifth year, a small sprout came out of the land. Within six months, the tree grew a hundred feet tall. "
"The little bamboo tree had been growing underground in the past four years, developing a root(根)strong enough for its ground growth in the fifth year. If it hadn't done this, it would not be so strong. So you know, all the time you were struggling, you were actually growing strong roots. "the old man said. Finally, the man thanked the old man deeply. Then he left the forest with the hope for life.
March 22 is World Water Day. It reminds us to save water, because water is the most important natural resource(资源)on the earth.
Water covers more than 70% of the earth's surface, but most of that is sea water. People can't use it directly in daily life.
Fresh water takes up only 2. 5% of the total water.
People in many places are facing serious water problems. One of them is water pollution. Many kinds of waste from cars, factories, farms and homes make rivers, lakes, and oceans dirty. Polluted water is very bad for people's health. And dirty water is also bad for sea life. Now, 34% of fishes are dying out.
The biggest source(来源)of pollution comes from cars and factories. In the beginning, waste from cars and factories pollutes the air. Then, when it rains, the rain water comes down and makes our drinking water dirty.
Scientists say that in 30 years, more than half of the people in the world won't have enough clean water. We have to learn how to save water. Here is some advice.
★Turn off the tap while you are brushing your teeth. You can save as much as 450 liters(升)of water each month.
★Leaky(漏水的)taps waste a lot of water. Fix them right away!
★You can easily cut your shower time short, and you'll be still clean.
★When you wash the dishes, don't let the water run.
★Only wash clothes when you have a lot to wash. If your washing machine isn't full, you're wasting water.
