【推荐2】People have seen the colorful shared bikes (共享单车) in the city streets around China for two years. People can rent (租用) them with a smart phone app and then park anywhere they choose. To relieve (减少) traffic jams and air pollution, many cities have introduced bike-sharing services. But sometimes, dreams are not so perfect.

     

It is true that it is convenient for people to go out by shared bike. As shared bikes become more popular, problems showed up. According to news reports, users treated shared bikes badly. After people used the bikes, some of them just threw them onto streets and even into the ditches (水沟). Some people stole the bikes or locked them up in chains (链条). A month ago, the police fined a man in Shanghai 1,000 yuan, because he stole a shared bike.

Besides, the damage to the QR codes (二维码) on the bikes has brought huge losses to bike-sharing companies, like Mobike (摩拜单车). If the QR code is bad, people cannot use the bike anymore. It can take several hundred yuan for the company workers to find a lost bike and repair it. Mobike has 100 credit scores for each user. Once the score drops to below 80, bike rental (租金) will go up five yuan per 30 minutes.

However, punishment may not be the best way to stop shared bikes from being stolen or damaged. Bike-sharing services will work better only if people follow the rules and show respect for the bikes.

【推荐1】① Our body language tells the world a lot about us. But can it change the way in which we see ourselves? The answer is Yes.

② Two scientists, Amy Cuddy and Danna Carney, who know much about body language, did a famous research. According to the result of their research, body language can change the chemistry of our brains. Some high-power body language can make you become confident. For example, you will feel confident when you hold your head high; you will feel confident too when you put your arms out wide as if you have won a race. However, some low-power body language can make you feel unconfident, such as sitting with your arms close to the body, sitting with your legs together or walking with your head down.

③ Why do all these happen? The scientists think the reason is that body language changes the amount of something special in our brains. It’s called hormone (激素). One kind of hormone can increase your confidence; another kind can increase your stress (压力). But too much stress hormone is bad for learning. It also increases the risk of health problems.

④ The result of the research is helpful for your studies. Please remember: try to use more high-power body language in your studies, and you will be confident. That is, always believe you can study well, act as if you were doing well, then you will make greater progress in real life.

What will astronauts (宇航员) eat when a space trip takes years?

“Lots of fresh vegetables,” says Dr. Janet Williams, whose team has 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 CO_2.

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?

A．It caused the gravity to change.

B．It encouraged the plants to grow faster.

C．It helped the plants to grow in the right direction.

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.	B．There was too much CO2.
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.

【推荐3】Do you sleep well? How much sleep is enough for you?

To stay in good health, experts say, adults should get seven to eight hours of sleep. Teenagers need nine to ten hours. And pre-school children need more than 10 hours of sleep a night.

Experts say the quality of our sleep becomes poor as we grow older. This happens because the brain unit that controls sleep begins to weaken slowly as we age.
