Storytelling
Storytelling has caught the human imagination for thousands of years. People everywhere have told stories to amuse, to teach, to remember, and just to pass the time. People started telling stories long before writing was invented.1.But people all over the world still tell one another stories out loud. A person who can tell a good story nearly always finds listeners.
Before people developed writing, storytelling was the most important way to pass along information. Anything a culture wanted to protect一its beliefs, its history, and its traditions—had to be told out loud. Each generation would tell the culture’s stories to the next.2.Knowledge passed on in this method is called the spoken tradition. Even cultures that know how to write still pass along some information in this way.
3.In other cultures only special storytellers were trusted to do this important job.A culture’s best storytellers had good memories. They could also make the stories very interesting, so people would listen and remember them. Sometimes people would sing the stories or tell them in the form of poems.4.
However, stories told aloud change over time as different people tell them. A storyteller might change a story in order to make it better. Or a teller may simply not remember all the details of a story. Unlike written stories, the spoken tradition is not created by any one person. 5.Sometimes the stories are collected and written down long after they have been created.
A.In this way the stories were passed along.
B.In some cultures everyone would pass along the stories.
C.Songs and poems can both make stories easier to remember.
D.Instead, a whole culture helps shape the changing stories throughout history.
E.Today stories are also written down in books and acted out in movies, TV shows, and plays.
What will astronauts（宇航员）eat when a space trip takes years?
“Lots of fresh vegetables,” says Dr. Janet Williams, whose team have spent the last 10 years learning how to grow plants in a space station. And it’s a good thing that she has already started her work, because space gardening can be really hard.
As usual, astronaut George White looked into the closed plant room. He had planted Dr. Williams’s quick-growing seedlings in it, but none of the stems were showing. He opened the room to check and found the problem. The stems weren’t growing upward and the roots weren't growing downward. On Earth, gravity（重力）helps a plant’s stems and roots to find “up”and “down”. However, in the space station, there was almost no gravity.
Dr. Williams suggested a solution: give the plants more light, as plants also use sunlight to find their way. And it worked. When the plants had more light, the stems turned up and the roots went down.
Now Dr. Williams was free to worry about the next problem:Would her baby plants live to flower? Can we grow food on a space journey?
Many plants died in the space station. Dr. Williams thought she knew why: the space plants were hungry for air. Plants live by taking up CO2 from the air. Since a plant uses it up in the air around, the plant needs moving air to bring more CO2 close to its surface! On Earth, the air is always moving. Gravity pulls down cold air, and warm air rises. And with these air movements, plants get enough CO2.
Many earlier experiments with plants in space had used closed rooms.Dr. Williams tried a new greenhouse that had a fan to keep the air move. The plants loved it. They flowered and even produced more seeds. Using Dr. Williams's method, astronaut George completed the first seed-to-seed experiment in space, and moved one plant closer to a garden in space.
“And this,” says Dr.Williams, “is good news for long-term space travel.”
