The Greek god Helios was said to drive the sun around the sky with his chariot (戰(zhàn)車). But now, these ideas have all changed. Nowadays, it is the sun that drives our “chariot” around the sky.?So what does all this mean? Well, quite simply, there is now a plane (or “chariot”) that is powered by the sun. It has special parts in its wings. These parts 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 (“太陽驅(qū)動”號). 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.

It is being more mon because restaurants are starting to create more dishes that include mushrooms.Mushroom growing is easy. To start, you need to have a space where you are going to grow these mushrooms. It does not have to be a huge space but just enough for you to grow as many mushrooms as you need. When you have found the space perfect for you, you can start researching what kind of mushrooms you want to grow. There are a lot of mushrooms to choose from and not all of them are suitable to eat.When you decide what kind of mushrooms you want to grow, you can start getting ready to plant the mushrooms. Sometimes you may want to hire some workers to help if you have a large mushroom farm, or if you are trying to start a professional mushroom growing business. Trying to have a business by yourself can be stressful. If you don’t have enough time to spend taking care of everything yourself, some helpers may be the best choice.After you have started the mushroom growing, you should regularly check that your mushrooms grow properly and that they are not being attacked by any pesticides (農(nóng)藥) or any other animals or something that could
