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.”

1.Why have Dr. Williams’s team tried to grow plants in space?

A.To produce fresh air for astronauts.

B.To help astronauts relax themselves.

C.To provide food for long space journeys.

D.To make the space garden more beautiful.

2.How did light help solve the problem mentioned in Paragraph 3?

D.It showed the astronauts where to plant vegetables.

3.Why did many plants die in the space station?

A.The light was too strong.

C.There was not enough room to grow.

D.The air condition was not good enough.

4.The underlined word “it” in Paragraph 7 refers to________.

A.the moving air B.the closed room C.the space journey D.the space garden

5.What can we learn about Dr. Williams’s team from the passage?

A.They mainly live on fresh vegetables.

B.They have successfully built a space garden.

C.They invented a special fan for their greenhouse.

D.They have worked on space gardening for many years.

Bike-sharing is new for short journeys in cities. It is a good choice for the big cities to develop healthily.

A report found that shared bikes started the nation's love for bikes again. The love is not only among young people born in the 1980s and 2000s, but also among people over sixty. Now they are choosing bikes instead of cars to make short journeys in cities. If you have a smart phone, the nearest bike equipped with GPS will be easily found through a certain app on your phone. It can also be unlocked through the app and left anywhere in public for the next user. The cost of riding depends on the time that you spend. Normally, every hour you ride, you just need to pay one yuan.

It is said that bike-sharing will help improve the cities' environment. It not only helps solve the traffic problems, but also will help to make more use of space in cities. Take Beijing as an example. If more people choose shared bikes, an area of five Bird's Nest Stadiums(体育场)will be saved.

At the same time, there are some problems with shared bikes that people need to solve properly. For example, some people park the bikes in their home; some break up the bikes on purpose; and others even throw them into the river. Facing all these problems, everyone should raise their own awareness of protecting the bikes. We should not only enjoy them, but also value them and put them to good use.
