Teenagers who spend more than six hours online on school days are more likely to be lonely and skip school,according to an international study.

The study examined the home Internet use,well-being(幸福) and behaviour of 296,000 15-year-olds in 41 countries.More than one in four spent more than four hours per day online outside of school.The study found lower levels of well-being among students who spent more than six hours per day online.They were twice as likely as teenagers spending one and two hours per day online to report that they felt lonely at school.These extreme Internet users were also especially at risk of "behaving in problematic ways at school,such as arriving late or skipping class".

The report said,"Lower levels of engagement(密切关系) with school may be connected to less sense of belonging at school.It is also possible that skipping class and arriving late for school are the consequence of lack of sleep among extreme Internet users."It adds,"Parents,schools and health professionals can work together to watch and plan children's use of new media."

The study also found that countries that invest(投资) heavily in Information and Communication Technology(ICT) in schools have seen no considerable difference in 15-year-olds' achievement in reading,maths or science tests.The study results suggest limited use of computers at school may be better than not using them at all.However,students who use computers very frequently at school do a lot worse in most learning outcomes.The report says,"In the end,technology can strengthen great teaching,but great technology cannot replace poor teaching."

(1)、The international study showed that ____.
A、half of the students spent six hours online every day B、extreme Internet users had lower levels of well-being C、teenagers spent much time online when they felt lonely D、most of the students were late for school after extreme Internet use
(2)、What can we learn from the study results?
A、Schools should invest more in ICT. B、Proper use of computers is helpful at school. C、Technology sometimes leads to poor teaching. D、Computer users perform well in maths at school.
(3)、Where does this text most probably come from?
A、An engineer textbook. B、A personal diary. C、A science news report. D、A computer book.

    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp.” he said.

    The lampbrella is a standard-looking street lamp fitted with an umbrella canopy with a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)first ensure that it starts raining and the motors open up in response to their sensors and then people can protect themselves from the rain under the canopies.

    In addition to the rain sensor, there's also a 360° motion sensor on the fiberglass street lamp which detects whether anyone's using the lampbrella. After three minutes of not being used, the canopy is closed.

    According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each lampbrella would offer enough shelter for several people. Being installed(安装)at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

    While there are no plans to take lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.

The rolling out of 5G services has triggered a wave of competition across the world. More importantly, it has started a race to develop 6G as the telecommunications sector has always been a hotspot for competition.

Compared with 5G technology, 6G will have lower latency, higher speed and more bandwidth. And this advanced technology will help connect the real world with virtual digital world. It will also make product design R&D(Research and development) and experiments significantly more efficient and greatly reduce their costs while making it possible to produce digital products. In the physical world through high-tech, including 3D printing. The seamless and intelligent connection of the physical and digital worlds will lead to a thorough reconstruction of the division of labor and societal cooperation.

In terms of economic development, 3G fostered e-commerce while 4G boosted e-commerce and mobile payment. 5G infrastructure building and application marked the beginning of intelligent manufacturing. Similarly, wireless cognition technology associated with 6G technology, once it matures, will further boost the development of the digital economy. In digital economy, intelligence based on big data will become the real force for innovation and 6G networks not only will be highways for transmitting data, but will also much more seamlessly integrate edge and core computing as part of a combined communications. This will provide many potential advantages as 6G technology becomes operational, including access to AI capabilities. Digital economy based on 6G will become the determining factor of the country's competitiveness in the future, and 6G technology with wireless cognition as its major characteristic will become core technology and main driver of the digital economy.

Starting with 5G our telecom industry, thanks to its extensive R&D input, has taken the lead in standardizing and manufacturing 5G telecom equipment,the competition in 6G will start with the setting of standards, which will determine the level of R&D needed for the launch of the technology and thus decide the market share of the emerging industry . As far as R&D in 5G technology is concerned. We have already enjoyed two advantages. first, it is a global leader in the telecom sector and has a solid reserve of talents. And second, it has a relatively complete industrial chain that covers R&D and design, manufacturing and application. and is home to leading 5G equipment maker. Recent history shows whoever leads the telecom technology sector sets the standards for telecom products and services. and plays a bigger role in the industry's future development . An official research team on 6G including the government. enterprises and research organizations has been established to obtain the advantage of 6G development competition .
