Taking away a city’s rubbish is a big job. Every day trucks come into a city to collect it. Most rubbish is made up of things we can’t eat or use. If we kept these things we would soon have a mountain of rubbish.
In some cities the rubbish is collected and taken outside of city to a dump (堆存处). Often the city dump is placed where the ground is low or there is a big hole. The kitchen rubbish is broken into small pieces and sent into the sewage system. The sewage system takes away the used water from toilets, bathtubs and other places.
To keep mice and flies away, some earth is used to cover the newly dumped rubbish. Later, grass may be planted on the rubbish-filled land. Finally, a house or a school may be built there, and then you’d never know that this had once been an old rubbish dump.
In other cities the rubbish is burnt in special places. The fire burns everything but the metal. Sometimes the metal can be used again in factories where things are made of metal. The food parts of rubbish are put in special piles (堆) where they slowly change into something called humus (腐殖质), which looks like black earth. It is rich with kinds of things that feed plants and help them grow.

In 1986, Honda made a robot called ASIMO. And now, it has been developed greatly. Standing at 130cm and weighing 54kg. ASIMO is very much like a small astronaut wearing a bag on the back. And he can walk, flight, climb and run fast. Isn’t it wonderful?
The world’s first robot teacher is Saya. With her human-like face, she can show expressions like happiness, surprise, sadness, dislike, fear and she can even smile or show anger at students, which look much like a real teacher’s. To do this, her rubber skin is pulled from the back with motors inside. And her eyes and mouth have wires(电线) too. She can also say some simple words like “hello” or “thank you”.
In the UK, the development of robots is exciting. The mini-robots will send food, clean floors, collect and throw away waste. These robots can open doors by themselves and stop if anything or anyone is in the way.
These mini-robots are very useful for controlling infection(传染). Usually clean and dirty work is done by the same person, but here, you’ll have robots that do”dirty work”, like collecting dirty sheets, or taking away hospital waste; and you’ll have robots that do”clean work”, like bringing meals or clean sheets to patients. The robots have separate work so there’s no way for infection, which is great. But of course, robots would not take the piece of humans, but would free up more time for nurses to be with patients.
But if this is what it’s like in 2011, what’s it going to be like to 2021?
