China has 410K5Gbase stations
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.
1. What can we learn from this passage?

Addiction to smartphones will result in poor sleep, according to a new study.
The study, published Tuesday in Frontiers in Psychiatry, looked at smartphone use among 1,043 students between the ages of 18 and 30at King's College London. Researchers asked the students to complete two questionnaires on their sleep quality and smartphone use, in person and online.
Using a 10-question scale that was developed to judge smartphone addiction in children, nearly 40% of the university students qualified as "addicted" to smartphones, the study found. “Our findings are in agreement with other reported studies in young adult populations globally, which are in the range of 30-45%,” lead author Sei Yon Sohn and her co-authors wrote in the study. "Later time of use was also significantly connected with smartphone addiction, with use after 1 a.m. increasing a 3- times risk," the authors wrote.
Students who reported high use of smartphones also reported poor sleep quality, the study found. That foils in line with previous studies that have found overuse of smartphones at night to be associated with trouble falling asleep, reduced sleep duration (睡眠持续时间)and daytime tiredness. That's likely because use of smartphones close to bedtime has been shown to delay the body's normal sleep - and - wake clock.
In fact, the No. 1 rule is "no computers, cell phones, and ipads in bed and at least one hour beforebed Dr. Vsevolod Polotsky, who directs sleep basic research, said in a recent interview. That's because "any LED light source from electronics (电子设备)may further hold back melatonin (褪黑激素)levels," Polotsky said. Melatonin is often referred to as a "sleep hormone," because we sleep better during the night when levels reach the top.
“This is a cross-sectional study, and it cannot lead to any firm conclusions about smartphone use as the cause
of reduced sleep quality, said Bob Patton, a lecturer in clinical psychology at the University of Surrey, via email.
4. How did Sei Yon Sohn's team begin their study?
A. By publishing researching papers.
B. By responding to others’ concern.
C. By collecting firsthand data.
D. By turning to related experts.
5. What did the study find about sleep quality and smartphone use?
A. 30-45% of the university students are addicted to smartphones.
B. High use of smartphones is related to poor sleep quality.
C. Overuse of smartphones leads to shorter sleep duration.
D. Use after 1 a.m. will result in smartphone addiction.
6. What is Polotsky's opinion on electronics ?
A. We should stop using them an hour before going to sleep.
B. LED light source from them will delay normal sleep- and- wake clock.
C. Reduced sleep quality has nothingto do with them.
D. No electronics should be used in bed at any time.
7. What can be a suitable title for the text?
A. Say No to Smartphones
B. Sleep Quality Can Be Improved
C. LED Light Source Causes Great Harm
D. Smartphone Addiction Ruins Sleep
C
The shade of a single tree can provide welcome relief from the hot summer sun. But when that single tree is part of a small forest, it creates a considerable cooling effect. According to a study published today in the Proceedings of the National Academy of Sciences, trees play a big role in keeping our cities cool.
According to the study, the right amount of tree cover can lower summer daytime temperatures by as much as 10 degrees Fahrenheit. And the effect is quite noticeable from neighborhood to neighborhood, even down to the scale of a single city block. “We knew that cities are warmer than the surrounding countryside, but we found that temperatures vary just as much within cities,” says Monica Turner, a professor in the department of Integrative Biology, Wisconsin-Madison University and a co-author of the study.
With climate change making extreme heat events more common each summer, city planners are working on how to prepare. Heat waves drive up energy demands and costs and can have big human health impacts. One
potentially powerful tool, the study's authors say, are organisms that have been around long before human civilizations could appreciate their leafy benefits. And those trees may be the secret to keeping the places we live livable.
Essentially, says Turner, roads, sidewalks and buildings absorb heat from the sun during the day and slowly release that heat at night. Trees, on the other hand, not only shade those surfaces from the sun's rays, they also release water into the air through their leaves, a process that cools things down.
To get the maximum benefit of this cooling service, the study found that tree cover must be more than 40 percent. In other words, an aerial picture of a single city block would need to be nearly half-way covered by a leafy green network of branches and leaves.
8. What can we infer from Paragraph 2?
A. Temperatures in cities mainly depend on their green coverage.
B. People living and working in cities must plant trees in summer.
C. Cities are warmer than the countryside because they don't have trees.
D. An area with more trees can be cooler than the other parts within a city.
9. Which of the following problems is caused by extreme heat events?
A. Severe damage of city facilities.
B. Serious human health problems.
C. Residents' growing demands for plants.
D. Unnecessary waste of energy resources.
10. Why are trees crucial to cities?
A. They help shade and cool the cities.
B. They make urban scenery beautiful.
C. They build up city cooling systems.
D. They essentially block and release heat.
11. What can city planners conclude from the study?
A. They should publish the study in a newspaper.
B. They should educate citizens to protect forests.
C. They should plant trees on roads and sidewalks.
D. They should cover nearly half the city with trees.
D
An anti-obesity program for Australian girls didn’t lead to any improvements in their diet, physical activities or body weight a year later, according to a new report.
Findings from the school-based intervention (介入), which involved exercise sessions and nutrition workshops for lower-income girls, are the latest disappointment in a lot of research attempting tohead offadult
obesity and the disease risks that come with it.
Especially during the middle-and high-school years, girls’ physical activity reduces obviously, according to lead researcher David Lubans, from theUniversityofNewcastleinNew South Wales,Australia. He said, “In the future we need to make the programs more interesting and exciting and present information in a way that is meaningful to adolescent girl.”
Lubans and his workmates conducted their study in 12 schools in low-income areas ofNew South Wales. At the start of the study, girls in both groups weighed an average of close to 130pounds, with about four in ten considered overweight. Over the next year, adolescents in the intervention group were given pedometers (计步器) to encourage walking and running and invited to nutrition workshops and regular exercise sessions during the schoolday and at lunchtime. Participation in some of those activities were less than ideal. For example, the girls went to only one-quarter of lunchtime exercise sessions, and less than one in ten completed at-home physical activity or nutrition challenges, the researchers reported. At the end of the year, girls in both groups had gained a similar amount of weight and there was no difference in their average body fat.
Preventive medicine researcher Robert Klesges said that although some anti-obesity programs have helped adults lose weight, the teen population has always been a source of failure for researchers. “The common belief is: nothing works,” he said. “And we have got to get beyond that.”
“We need to think outside the box,” said Klesges, who wasn’t involved in the new study. “That could include learning from what has worked in adult studies, such as giving meal replacement drinks or prepared foods to teens who have trouble making changes to their diet. Or, it could mean using a “step-care” method — rather than researchers or their doctor telling them to keep doing the same thing.” Klesges said.
12. The underlined words “head off” in Paragraph 2 can best be replaced by “________”.
A. damage
B. defend
C. prevent
D. affect
13. The methods used in the program to stop obesity don’t include ________.
A. walking and running
B. inviting them to nutrition workshops
C. joining exercise sessions regularly
D. giving meal replacement drinks
14. The main reason for the failure of the anti-obesity program is probably that ________.
A. the participants didn’t take an active part in it
B. the program was not interesting and exciting to participants
C. the participants didn’t get extra nutrition or exercise help
D. the program didn’t pay attention to healthy exercise
15. What can be inferred from the last paragraph?
A. As researchers, it is important to have creative research methods.
B. Researchers need to give meals or prepare foods to participants.
C. Teen girls have no difficulty in making changes to their diet.
D. Some ant-obesity programs have not helped adults lose weight.

Dear Diary,
Here I am in the middle of a city, 350 miles far away from our farmhouse. Do you want to know why we move last week? Dad lost his job, and as Mom explained, “He was lucky to find other one.” His new job meant I had to say goodbye to my classmate, my school, or just everything else I love in the world. To make matters bad, now I
have to share a room with my younger sister, Mia. Tomorrow is first day of school. I am awfully tiring, but I know I will never fall sleep.
Good night and remember, you, dear Diary, is my only souvenir from my past life and my only friend.
