Astronauts (宇航员) face many problems when living in space stations. One of them is food. People on Earth put together all the meals first and then send these meals to space stations by space shuttle. Because the food has to last a long time (sometimes up to three months), people have to store a lot of it in cans. The space station does not have a fridge, but it has a cool room to keep fruit and vegetables fresh. Astronauts also eat many other foods such as dried meat that do not need special care.
Without the help of gravity sitting down to eat can be difficult. Astronauts sometimes have to fix themselves to the wall while eating. They also have to be very careful so that food does not float away.
Do you know something about the moon? You can (seeing) it at night. Sometimes it looks round and (brightly). It also looks quite near. the moon is very far from the earth. If you take spaceship, you will get there in more than three days. The spaceship (go) very fast, at 11 kilometers a second. In 1969 two (American) got on the moon by spaceship.
There are no living things on the moon there is no air or water there. That's why people can't (liveness) there. But you may know you can jump much higher there than the earth. It's full, isn't it?
