China built 257,000 new 5G base stations in the first half of the year, according to the Ministry of Industry and Information Technology (MIIT).
Shipments of 5G phones reached 8623 million unis in China, with 5G package users hitting 66 million by the end of June, said Wen Ku, head of information and communication at the ministry.
To give full play to the commercialization of 5G, more policies should be implemented to boost the vitality of the market, Wen said, adding that international cooperation in 5G technology, industry and application should be strengthened.
AG600 seaplane’s test flight
Kunlong, China’s homegrown AG600 large amphibious aircraft, conducted its first sea-based test flight on Sunday morning, marking a new milestone in the program.
The AG600 is China’s second amphibious aircraft, after the SH-5, which was developed in the 1970s for military purposes and has been retired for a long time.
These specifications make it the world’s biggest amphibious aircraft, surpassing Japan’s ShinMaywa US-2 and Russia’s Beriev Be-200.
Once in service, it will put an end to the absence of a large rescue aircraft in China and will be very useful in the national emergency rescue and disaster relief systems.
Beidou products land abroad
According to Ran Chengqi, director general of China Satellite Navigation Office, Beidou has been constantly deepening its compatibility, interoperability and cooperation with the US’ GPS, Russia’s GLONASS and the EU’s Galileo. It has also entered international organizations of civil aviation, maritime affairs, search and rescue satellites and mobile communication.
BDS-based services have been successfully applied in land mapping, precision farming, digital development and smart port construction in member countries of ASEAN, South Asia, Eastern Europe, West Asia and Africa.

2 . Volunteering abroad is a great way to help others，improve your skills and become a more confident，independent person. If you are interested in volunteering abroad，here are some places to go.
Australia
If you seek a life on the beach，in a great climate with friendly people，Australia might be your best bet. With thousands of volunteers already signing up to leave for Australia during the holidays，it will be a very popular option.
Brazil
This vast country has some great opportunities on offer and is especially popular this year. A lot of volunteer work is available in Brazil centers on conservation and ecological projects. With the world's largest rainforest in Brazil，of which huge part is in danger，there are lots of different jobs you can do.
Kenya
Kenya is the destination for those seeking an African experience. Generally volunteers in Kenya work in orphanages (孤儿院) or with local children living in slums. There is a great demand for volunteers in Africa because many people live in poverty，so if you truly feel like making a difference to a community，Kenya should be at the top of your list.
Costa Rica
Golden sandy beaches，clear coastlines and beautiful cities are what Costa Rica is all about. Because of its small size，you can see a lot of the country in just a short time. You can really make the most of your time as a volunteer. A lot of work is needed with wildlife and ecological work，so if you want to look after turtles on the beach，Costa Rica could be just the place for you.

3 . When the Bayside campus of Shekou International School (SIS) are still kept shut because of the COVID-19 pandemic, teaching activities at the school have been resumed online since Feb. 3rd, 2020.
The school is using popular apps and software for online learning. Video conferencing and office automation are used to help teachers keep track of students’ conditions and communicate with their workmates across the world. Teaching online also offers a new experience to the teachers to update their teaching methods and to step out of their comfort zones.
Staying in Phuket, Thailand, science teacher Riley Laird records videos on a 10-year-old green sea turtle named Marlin and the local turtle sanctuary as part of the online classes on ecosystems for Grade 7 students. “I want to connect our learning with the reality. The sanctuary sends us updates on the turtles’ health and progress. They say that Marlin is likely to be released into the sea in mid-June,” says Laird.
Rebecca Wallace is a Grade 4 teacher at the school, staying in her mother’s home in New York. From 8 p.m. to midnight every day, she starts teaching mathematics and arts to her students living in different time zones. Though teaching nearly around the clock, Wallace says that she is getting to know the students better in terms of their homes, family and even pets.
Greg Smith, head of SIS, names the online teaching period a “new normal” at the school. “Students are now more skillful at using technology than before. They see that communication is the most powerful part of being an effective learner and can use the tools to shrink distance and time. The “new normal” will offer more choices for connection to the world and more focus on creating real solutions,” he says.
According to the school, 68% of its students are staying in Shenzhen while 27% of them are staying abroad for the epidemic.

4 . Every man wants his son to be somewhat of a clone, not in features but in footsteps. As he grows you also age, and your ambitions become more unachievable. You begin to realize that your boy, in your footsteps, could probably accomplish what you hoped for. But footsteps can be muddied and they can go off in different directions.
My son Jody has hated school since day one in kindergarten. Science projects waited until the last moment. Book reports weren’t written until the final threat.
I’ve been a newspaperman all my adult life. My daughter is a university graduate working towards her master’s degree in English. But Jody? When he entered the tenth grade he became a “vo-tech” student (技校学生). They’re called “motorheads” by the rest of the student body.
When a secretary in my office first called him “motorhead”, I was shocked. “Hey, he’s a good kid, ” I wanted to say. “And smart, really.”
I learned later that motorheads are, indeed, different. They usually have dirty hands and wear dirty work clothes. And they don’t often make school honor rolls (光荣榜).
But being the parent of a motorhead is itself an experience in education. We who labor in clean shirts in offices don’t have the abilities that motorheads have. I began to learn this when I had my car crashed. The cost to repair it was estimated at $800. “Hey, I can fix it,” said Jody. I doubted it, but let him go ahead, for I had nothing to lose.
My son, with other motorheads, fixed the car. They got parts from a junkyard, and ability from vo-tech classes. The cost was $25 instead of $800.
Since that first repair job, a broken air-conditioner, a non-functioning washer and a non-toasting toaster have been fixed. Neighbours and co-workers trust their car repairs to him.
These kids are happiest when doing repairs. They joke and laugh and are living in their own relaxed world. And their minds are bright despite their dirty hands and clothes.
I have learned a lot from my motorhead: publishers need printers, engineers need mechanics, and architects need builders. Most important, I have learned that fathers don’t need clones in footsteps or anywhere else.
My son may never make the school honor roll. But he made mine.

5 . Bill Bowerman was a track coach. He wanted to help athletes run faster. So he had learnt how to make running shoes. He had also started a shoe company with a friend. It was 1971.Running shoes at the time were heavy. They had spikes(鞋钉)on the sole(鞋底). The spikes tore up the track and slowed down runners.
To make a lighter shoe, Bill tried the skins of fish. To make a better sole, he wanted to replace the spikes. Bill dug through his wife Barbara's jewelry box. He hoped to find a piece of jewelry with an interesting pattern. He would then copy the pattern onto the new soles. Nothing worked. Bill was defeated.
Then, one Sunday morning, Barbara made Bill waffles(华夫饼)for breakfast. Bill watched her cook.
He studied the criss-cross pattern on a waffle iron.
Inspiration struck. The pattern on the waffle iron was just what Bill was looking for. The squares were flatter and wider than sharp spikes. The pattern would help the shoes hold any surface without tearing into it.
When Barbara left the house, Bill ran to his lab. He took the liquid chemicals that, when mixed, would harden into the sole of a shoe. He poured the mixture into the waffle iron---and the Waffle Trainer was born.
Bill’s company put the Waffle Trainer on market in 1974.It was a huge hit. Maybe you’ve heard of that company---it’s called Nike. And today it’s worth around $100 billion.
It was the waffle iron that had changed the course of Bill’s life---and helped turn Nike into a well-known name. Today, the waffle iron is kept at Nike headquarters. It serves as a reminder that if we keep trying, we can find a solution to even the most difficult problems. And those solutions can come from unlikely places, even the breakfast table.

7 . City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes,then, urban trees will likely absorb less CO2 from the air thah forest trees.
As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石）fuels，have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.
Studies had shown forests readily absorb CO2，but there hadn’t been much data on whether city trees grow， die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out.
To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree’s diameter increases as it grows, just as a person’s waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years’ tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.
City trees grew faster because they had less competition for light from their neighbors. In a forest，trees tend to grow close together，shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮）in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.

9 . The future of Australia’s solar industry is looking bright after a record 3.5m panels(嵌板)were installed on rooftops last year, giving the equal output of a medium-sized coal-fired power station. The record 1,057 MW of capacity (产能) in small scale systems installed across the country broke the previous record set in 2012, figures from the Clean Energy Regulator showed on Tuesday.
Australia’s solar power prosperity could almost double capacity in a year, The data also revealed that the average system size has also doubled since then from three to six kilowatts as average prices continued to fall. A fully installed 5KW system costs an average of $5,930 in Australia, according to the energy broker Solar choice. net. au. Its records show that the price has roughly halved in many capital cities since 2012.
The regulator’s executive general manager, Mark Williamson, said there was increasing interest in renewals as a way to take control of electricity bills. But more importantly, he said it was also good news for reducing carbon emissions,
“We are seeing a wide cross section of Australians—households, community centers, schools, and small businesses—receiving rewards under the small scale renewable energy scheme,” Williamson said, “Our data shows consumers are embracing renewable energy to take control of their electricity bills. ”
In 2017, there was a 41% increase in installing renewable energy capacity across all states and territories compared to 2016. Queensland led the way with installed capacity at 295MW, with the Australian Capital Territory taking top place for the biggest annual increase by 57 %. “I he data collected by the Clean Energy Regulator in 2017 reflects the industry is going from strength to strength, It looks like 2018 will be another big year for the solar industry.”
The total of installed capacity for last year is expected to rise to 1,070MW when all the data is collected. A large coal-fired power station such as Loyd Yang A in Victoria’s Latrobe Valley has a capacity of 2, 200MW.

10 . My mother died in August 2005. Eight months later, I began to come out of the fog of sadness and depression to find a new purpose for my life.
Like many of my generation, I had lived only for myself —traveling, acquiring possessions, rising to a position of importance and seeking financial rewards. I was “charitable” and “volunteered” for various causes, but really didn’t give of myself.
In the spring after my mom’s death, I found myself waking in the middle of the night with one thought. I felt forced to offer myself as a living kidney donor. My husband Robb had received the gift of life through a kidney transplant(移植)from a dead donor in 1999, so I was familiar with the enormous need for donors and knew several people who were waiting for a lifesaving transplant. I decided to offer myself to be matched with the most compatible(互不排斥的)person on the waiting list at my local transplant center.
I was paired with 71-year-old Dee from New Jerse who had survived for six years on peritoneal dialysis(腹腔透析). At her 70th birthday, her family threw a big party as they did not expect her to live much longer. Dee has become my very good friend. Almost two years after the transplant, I was privileged to celebrate her 50th wedding anniversary with her husband, their five children and their extended family.
In donating my kidney, I extended myself in a way far beyond what I ever believed was possible. I did so in honor of my mother who sacrificed so much for me and my sisters, and in memory of my husband’s donor who extended her 1ife through him.
I encourage all who enjoy the gift of good health to share with others, either as a living donor or by appointing organ donation upon death. By extending yourself through organ donation, you will live on through others in an extraordinary way and give comfort to your loved ones.
