    THE HISTORY OF LIVING IN SPACE

    Space travel is nothing new. The first spacecraft with a human on board blasted into space In 1961. since then, people have not only been travelling to space, but many of them have also lived there for extended periods.

Food

    All the meals on space stations are put together on Earth and sent to the space station, along with the astronauts, by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be preserved by dehydration or canning.

    The space station does not have a freezer to preserve food, but It does have a cool room to keep fruit and vegetables fresh.

Astronauts also eat many other foods such as cereals, cereal bars, nuts and dried fruit that do not need any special preparation.

    Eating

    Astronauts have a set timetable each day. This tells them when to do everything, including when to have their meals. At meal preparation time, they start getting their food ready, which often includes adding water to re-hydrate the dehydrated foods.

    Without the help of gravity, sitting down to eat can be tricky. Astronauts sometimes have to strap themselves and their food into place. Because of lack of gravity, astronauts cannot use ground salt and pepper, and all drinks must be taken from bottles. They also have to be careful that crumbs do not fly off and get stuck in vents and instrument panels.

Make memories of ginkgo (银杏)leaves

    Autumn is the season of harvest (收获). Leaves turn golden and are blown around by the wind. The ginkgo is one of my favorite trees.

⑴I love its beautiful golden leaves which look like fans. This autumn, I picked up some ginkgo leaves. I cleaned and dried them in the sun. When they are ready, they will be my specimens (标本). And I will put them in my books and use them as bookmarks. ⑵They will remind me of the season whenever I open my books. They are my memory of this autumn.

    One day a tiger catches(抓住)a fox in the forest. Before the tiger could eat him up, the fox cries out, "You can't eat me. Don't you know that I'm king of the forest. If you eat me up, all the other animals in the forest will be angry with you. "The tiger doesn't believe him." How can such a small animal be king of the forest?" He asks himself. "If you don't believe(相信)me," the fox says, "then take a walk with me in the forest．You can see for yourself whether(是否)they are afraid of me." The tiger thinks it is a good idea, so the fox walks in front and the tiger goes behind. When the other animals see the tiger coming, they run away as fast as they could.

    "See for yourself, Mr. Tiger," he calls out quickly. "All the animals are afraid of me."

    "Yes, yes," the tiger says. "You are quite right." He then lets the fox go.
