1 . In the United States，a company is working on a project that could change the way we think about public transportation.Its planned system would move people around in steel tubes.Those passengers would be traveling at speeds of up to 1,200 kilometers per hour.
The futuristic steel tube transportation system is called Hyper1oop.Workers plan to test the system next year in a specially built community called Quay Valley.The town will be powered entirely by energy from the sun.
The Hyperloop transport system is the idea of businessman Elon Musk.Dirk Ahlborn is head of Hyperloop Transportation Technologies.He says his company has taken Mr.Musk’s idea and is developing a system that will be safe，environmentally friendly and fast.
“It’s 100 percent solar powered…we’re not going to get up to 760 miles per hour，but we believe we can actually break the records that are existing right now.”
This means that a four-hour drive from Los Angeles，California to Las Vegas，Nevada，could someday take only 30 minutes by Hyperloop.The system involves a series of capsules that float inside a long tube.These containers would not need to travel along a pathway or track.The system has been designed to operate above or below ground.
“Inside the tube you create a low pressure environment very similar to an airplane that’s at high altitudes.So now the capsule travelling inside the tube doesn’t come up against as much resistance，and therefore can travel really fast with very little energy.”
Dick Ahlborn and his company will use an eight—kilometer track in Quay Valley to find the best way to set up passenger traffic and repair capsules.A larger system will cost an estimated six to $10 billion to build.If Mr.Ahlborn and his company succeed，we may one day see these very fast Hyperloop capsules speeding through tubes around the world.

2 . The world is a greener place than it was 20 years ago. A study published in the journal “Nature Sustainability” said that recent satellite data reveals a greening pattern that is strikingly prominent in China and India. The study shows that human activity in China and India dominates this greening of the planet, thanks to tree planting and agriculture. The effect comes mostly from ambitious tree-planting programs in China and intensive agriculture in both countries.
“China and India account for one-third of the greening, ” said lead author Chi Chen of Boston University. “ That is a surprising finding, considering the vague idea of land degradation (毁坏) in populous countries from overexploitation, ” added Chen.
China alone accounts for 25 percent of the global net increase in leaf area with only 6.6 percent of global vegetated area. The greening in China is from forests (42 percent) and croplands (32 percent), but in India, it is mostly from croplands (82 percent) with minor contribution from forests (4.4 percent).
China’s outsized contribution to the global greening trend comes in large part from its programs to conserve and expand forests with the goal of preventing land degradation, air pollution, and climate change.
“Once people realize there is a problem, they tend to fix it,” said Rama Nemani, research scientist and co-author of the study. “In the 1970s and 80s in India and China, the situation around vegetation loss was not good. In the 1990s, people realized it, and today things have improved. Now we see that humans are contributing.”
Land area used to grow crops is comparable in China and India—more than 770, 000 square miles—and has not changed much since the early 2000s. Yet these regions have greatly increased both their annual total green leaf area and their food production.
This was achieved through multiple cropping practices, where a field is replanted to produce another harvest several times a year. Production of grains, vegetables, fruits and more have increased by about 35%～40% since 2000 to feed their large populations.

3 . You may have visited antique stores and found cutting-edge goods in second-hand furniture stores, but have you ever stooping? On the streets of big cities at night, some young people are “looking for something”. Obsessed with the spiritual core of the old thing recycling, they fell in love with it. But what exactly is stooping?
In fact, this English word originally meant “bending over”, and now refers to a way of life of picking up discarded items and renovating and recycling old things, which originally emerged in New York and other foreign big cities.
Since the beginning of last year, the trend of “stooping” has spread to many big cities in China and many young people look for second-hand items such as discarded furniture on the streets, take home and repurpose them with a new look. In order to make the flow of information better, some “stoopers” have also built communities where group members can share “treasures” on the street with each other.
Mikiko, 27, is reportedly one of the first people in China to get involved in practicing stooping. At first, she posted online things that people no longer use, want to throw away, or exchange at home, and slowly hundreds of messages flooded in and since then, stooping has become more and more popular among young people. Mikiko admitted that she was surprised that the concept has become a hit on social media, as older generations often stigmatize picking up things from the street or using second-hand goods. “People like my mom consider stooping as’rubbish-picking’, and people will be looked down upon by doing this.” She even created an app called “Grecycle” where people can give away or take unwanted items for free, hoping people may realize that stooping can also be about doing good and helping others.
This generation of young people has given “new life” to old things, practiced social responsibility in their own environmentally friendly ways in life, and also contributed to the circular economy and sustainable society.
1. What do we know about “stooping” in this text?| A．It was developed in England. | B．It equals to rubbish-picking. |

| B．To argue about the misuse of good treasure. |
| C．To share the information of the discarded items. |
| D．To make some comments on the abandoned items. |
