In the universe, as we all know, there is the Sun, the Moon, the Earth and a good many stars. Through our geography lessons, we know the Earth goes around the Sun, and the Moon goes around the Earth. We have day and night because the Earth keeps turning all the time. When our part of the Earth turns to the Sun, it is day. When our part of the Earth turns away from the Sun, it is night.
Just because the Moon is closer to the Earth than the Sun, it looks much bigger than the Sun. Big things will look smaller when they are further, and small things also look bigger when they are nearer.
The Sun is big enough to give out very strong light. The Moon can't give out any light at all, but it looks quite bright, too. Why? In fact, the light from the Moon comes from the Sun. The Moon looks much bigger and brighter than the stars. But actually the stars are much bigger and brighter than the Moon. They look smaller than the Moon also because they are farther away from the Earth.
There are many other planets in the universe. But of all the planets, only on the Earth there are living things and people can only live on the Earth, too. But at 9: 00 a. m. on October 15th, 2003, Chinese pilot Yang Liwei was sent up to space. He stayed there for over 21 hours. It was the first time for Chinese to get into space.
I'm sure you all know how important recycling is. Recycling is when you take old things and turn them into new things. It sounds like magic. But it's actually very scientific.
| Material | The first thing you have to do is to collect items that can be recycled. Only certain materials can be recycled. These include things made out of paper, metal, glass and plastic. |
| Daily things | Can you think of everyday items made of these materials? Soda cans are good example. They are made out of metal. Magazines and newspaper are made out of paper. So are cereal boxes. Some bottles of juice are made out of glass. Bags and yogurt containers are made out of plastic. There are many things that can be recycled. |
| Loop | These things are usually stamped with the recycling loop. It has 3 arrows that go in a triangular (三角形) circle. This shows that cycle (循环) continues. Items are thrown away but continue their lives as something else. |
| Process | Let's go back to the process of recycling. ①The items are put in a recycling bin. ②A truck carries the items to a recycling plant. ③The materials are separated and squashed (被压扁成) into square cubes. ④Companies buy and turn them into new products. |
