Gardening is popular in many parts of the world. This outdoor activity gives us beautiful plants, pleasant smelling flowers and fresh fruits and vegetables. But it also does a lot of good to our health.
Gardening connects people. When you are gardening, you are outdoors. So it is a perfect chance to meet and spend time with your neighbors. Most people love to talk about their hobbies, and gardeners are no different. They usually enjoy showing people what they are growing. And most enjoy sharing advice and stories about their gardens almost as much as sharing flowers and vegetables from their gardens.
Gardening is a great activity for children. It gets them outdoors and off computers, televisions and cell phones. Gardening is also a great teacher. It can teach a child about where food comes from and healthy eating. It also helps them to understand that the natural resources (资源) are not endless and the importance of using them carefully.
Then, when you garden, you must move around. All the different movements needed for gardening, like bending and lifting, work small muscles (肌肉) in the body. And you can easily get good exercise when you are digging holes or pulling grasses.
In a study, researchers looked at more than 2, 800 people over the age of 60. They studied their lifestyle habits, activities and health over a 16-year period. They found that gardening could lower the risk of future dementia (痴呆) by 36%. Gardening requires people do many repeated actions, such as picking off dying flowers. These actions have a calming influence on the brain. The brain is still active but not in the same way when we use computers. You’ll feel wonderful when what you grow in a garden looks, smells, feels and tastes good.

【推荐2】A group of scientists in labs spread across Europe, the U.S. and Nepal have been working on Qomolangma “remotely”. The project’s goal is to turn the world’s highest mountain into a huge climate laboratory.
During April and May last year, a team of more than 30 biologists, glaciologists, geologists, meteorologists, and geographers fanned out across Qomolangma’s southern side, conducting fieldwork high on the mountain. “We believe the best way to get a full scientific picture of Qomolangma is not just to do one kind of science,” says Paul Mayewski of the University of Maine, the leader of the effort.
Each individual study promises a unique picture of the mountain’s climate-past, present, and future. Ice cores will allow scientists to go back in time-tens, hundreds and perhaps thousands of years to learn about the environment. Snow and water samples give a look at what’s happening on the mountain, today, including the future of the glaciers. The team also fixed a network of automated weather stations, which will document upcoming weather trends for years to come.
One of the hardest tasks fell to Mayewski’s colleague Mariusz Potoeki, who hoped to drill ice cores at several places on the mountain, including the South Col (25,938 feet) and the top of Qomolangma (29,035 feet). The job required a specially designed drill system powered by batteries, and an excellent team to figure out how to prevent the cores from becoming liquid during their long journey back to the University of Maine’s laboratory for analysis.
Potocki abandoned his summit attempt due to the crowds of normal climbers. To his relief, Potocki succeeded in taking the highest ice core ever recovered, at just above Camp Four-26,312 feet above sea level. “The ice doesn’t lie.” Mayewski says. “The very idea that the highest part of the planet hasn’t been spared from human activity ought to be a real wake-up call for everybody.”

【推荐3】One of the greatest mysteries in science is just how Earth went from a planet with minimal oxygen to the breathable air we have now. Scientists long figured that cyanobacteria (蓝细菌) were involved, but couldn’t tell what started the great oxygen-producing cycle.
A new study published in Monday’s Nature Geoscience may provide the key. It theorizes that Earth’s gradually lengthened day from six hours to the current 24 hours kick-starts cyanobacteria into producing lots of oxygen, making most of life as we know it possible. Here are the takeaways of the study.
About 2. 4 billion years ago, there was so little oxygen in Earth’s atmosphere that it could barely be measured, so no animal or plant could live. Instead, lots of bacteria breathed in CO2, and in the case of cyanobacteria, produced oxygen in the earliest form of photosynthesis (光合作用).
At first it wasn’t much. But in about 400 million years, as Earth’s rotation (旋转) gradually slowed down and the day was lengthened from six hours to the present 24 hours, the cyanobacteria breathed more and more oxygen into Earth’s atmosphere until it reached one-tenth the amount of oxygen we have now. The increased oxygen allowed plants to join in the oxygen-making party.
The authors of the study put their theory to test with the bacteria found on a 24-meter-deep seabed in Lake Huron. They exposed the smelly bacteria, which are very similar to the cyanobacteria living around 2. 4 billion years ago, to varying amounts of light, and found that the more continuous light the bacteria got, the more oxygen they produced.
“What makes the idea so convincing is that it doesn’t require any big biological changes in bacteria or the world’s oceans,” said Tim Lyons, a professor at the University of California, Riverside, who wasn’t part of the research team. “This may be a simple but plausible explanation for Earth’s oxygen increase.”

【推荐1】A serious problem for today’s society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.
First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs. Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.
In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions (慈善机构、福利院)should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young .
One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.
To sum up, all these options have advantages and disadvantages. Therefore , it is reasonable to expect that some combinations of these options may be needed to provide the care we hope to give to our elderly generations.

【推荐2】When is the right time to get kids involved in teamwork and what does it mean to be part of a team? There are many great ways to introduce kids to team building. Use team building games and activities to get kids to understand the meaning of being in a team.
Try to find some games that have kids work together on some kind of problem solving. Children naturally have a shorter attention span (一段时间) than adults so present it in a funny way. Create a reward system for teams that are able to work together in order to reach a common goal. When they solve the problem and receive a reward, it gives them initiative to keep working hard and cooperating with others. The best games are those that require direct communication between team members.
Organize a game of 20 questions for the kids to play while building a team. Draw up a series of cards with different questions on each. Have each child select a card and then ask another question on it casually. It’s a great way for the kids to share and discover common interests. Kids need to be entertained and social when in a large group. This will lighten the mood greatly and help the quieter team members to come out of their shells.
Have the kids sit in a circle or around a table and share their favorite things. Start with something like movies or books and move on to anything from toys to animals. Sharing interests creates discussion. When you share interests with someone, it is easier to relate to them. Kids finally want to be friends with most other kids. Encouraging them to get along socially is always positive. By sharing interests they can form valuable bonds that will serve them as both individuals and as a team.

【推荐3】Most people have map apps on their phones that can show their location and guide them to where they want to go. But how do these apps know your location at any time or place? They find you by using satellite navigation(satnav)systems(卫星导航系统).
A satnav system uses groups of satellites to find the user’s location. This location information is then sent to a receiver, such as a smartphone.
The first satnav system was the Global Positioning System(GPS),which belongs to the United States. First used in 1964, the system is the world’s leading satnav system. But China’s satnav system, Beidou, has overtaken(超过)GPS in size, Japan’s Nikkei Asian Review reported.
China sent Beidou’s first navigation satellite into space in 2000. China also became the third country to build a satnav system after the US and Russia, People’s Daily reported. As of right now, over 30 countries in Africa and the Middle East are using the Beidou system.
With its world-leading technology, Beidou is leading Chinese citizens to a better life by playing significant(重要的)roles in different areas,according to Xinhua News Agency.
For example, as of April, over 6.2 million vehicles(车辆)in China were using Beidou for navigation, according to a report on the Beidou system’s construction(建造)and development.
At the newly-built Beijing Daxing International Airport, Beidou has been used to keep track of(追踪)loading and unloading vehicles indoors and outdoors. When the airport fully opens, each baggage cart will have Beidou navigation equipment to help passengers get their luggage faster.
