18．　　In the future, we could all work and live in buildings with their own ecosystems (生态系统). They are made to produce more energy than they use.
　　Toby is an engineer from Europe. He has now made wonderful models, showing what this new building could look like. He said he was suggested by a kind of tree to create the towers. The Hyperion, found in Northern California, is the tallest tree in the world, reaching 115 m. The buildings will be 120 m high and have 1, 000 homes, offices and working spaces, gyms, restaurants and swimming pools.
　　Because of the ecosystems, the buildings will also make fewer diseases. The buildings will have city farms and small animal farms producing eggs and milk. "Farming can bring methane(甲烷) that produces energy, and then the energy is supplied to homes, " said Toby.
　　Toby has had many excellent designs. At the end of last year, he also showed designs for eco﹣friendly (环保的) ocean buildings. The eco﹣friendly buildings don't need coal or oil as they produce their own energy and heat.

19．　　Can you imagine astronauts' everyday life in space?They also need to cat, sleep, exercise and relax. They do the same things as us, but they do them differently.
　　On the earth, we put food on a plate. Gravity (重力) holds the food down and keeps it on a place. But there is almost no gravity in space, so food can float (漂浮) away, and astronauts must eat carefully.
　　Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a sleeping bag. They tiethe bag to a wall so that they won't float away at night.
　　Exercise is very important in space. On the earth, your legs carry your body. But in space, astronauts float, so they do not use their legs often. This is very bad for their legs, so they must exercise for thirty minutes every day.
　　After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families on the radio. Sometimes they just enjoy floating in the air.
