【正文】 arts absorb power from the sun. They absorb so much power that they can carry on flying at night. In the Greek myths (希臘神話), Helios had to take a break at night. It seems we’re finally even more efficient than the gods themselves.This plane is called Solar Impulse (“太陽(yáng)驅(qū)動(dòng)”號(hào)). It will fly across the US in May. This is very important for the future of the world.So why is solar energy so good for us? Well, other kinds of energy cause a few problems. If you live in China, you’ve probably noticed the pollution. This is caused by burning coal or gas to make energy. The heat and chemicals (化學(xué)制品) from this make things work. But if we use the heat from the sun, we don’t have to burn anything, and there’s no pollution.Solar energy is not all there yet. It needs to be improved. But the best thing about it is that, unlike coal and gas, it doesn’t run out. Solar Impulse could keep flying forever. Well, actually, the sun will run out too, one day, but not for another 5 billion years. That’s a pretty long flight.41. What does “chariot” really refer to in the last sentence of Paragraph 1? A.
