For the first time in history, China    1    (overtake) the United States in the number of supercomputers. Presently, China has    2    total of 202 of the world's 500 fastest computers, up from 159 half a year ago. The number of US supercomputers has dropped to 144.

The world's    3    (powerful) computer is located in China. The Sunway Taihu Light, at Wuxi can do 93 quadrillion calculations per second. The fastest US computer, the Titan, is ranked fifth    4    Europe's speediest computer is Switzerland's Piz Daint, ranked third.

Supercomputers are machines that occupy entire    5    (building) and use the combined power of thousands of processors. They    6    (use) to carry out special tasks that involve a huge number of calculations. Among them are weather forecasts and climate studies, as well as strategic tasks like nuclear weapons simulations (模拟).

China's highest position in the world of supercomputing reflects the country's investment in research and    7    (develop). One-fifth    8    the money used on these fields around the world is spent in China.

On the other side, many Chinese systems have been created    9    (earn) money. Processing power is rented to other national and international companies.

For years the speed of supercomputers has     10    (steady) increased although since 2012 this increase has slowed down.

Since ChatGPT’s launch in November last year, it has become an immediate hit that is both entertaining and alarming     1     (it) users. Given a command or question, the chatbot is able to return convincing essays, simple recipes and even life advice in a matter of     2     (second). This impressive achievement     3     (obtain) by a large language model. Many are wondering     4     could be next for this technology and where the technology could end up.

In recent years, shared vegetable plots     1    (find) in the city’s suburban (郊区的) districts in Shanghai as more white-collar workers turn to farming     2    (escape) the pressures of city life.

Yang Hui is one of them. He has rented a 20-square-meter vegetable plot for 1600 yuan per year. The family tends radishes (白萝卜), lettuces and other vegetables they have planted. When they aren’t around during the week,     3    (professional) take over the work.     4     (found) by Chen Yougui     5     October 2022, the shared farm spans about 13.33 hectares (公顷) and comes with shared vegetable plots, barbecue pits and leisure areas. According to Chen, the monitoring system covers     6     entire farmland, allowing members to view their vegetables and fields remotely through their phones.

This farm has about 200 members, some of     7     even raise chickens and ducks running in the fields. Interestingly, each animal comes with its own QR code (二维码). The farm also uses technology to ensure that the chickens and ducks don’t go missing     8     run in someone else’s plot.

Those who wish to     9    (active) participate in the cultivation (种植) of their crops, mainly from the older generations, can opt (选择) for the package to plant by     10    (they). Meanwhile young customers, like Yang, usually choose a package that comes with additional services from the farm to care for their plants whenever needed.

What would you do if the Internet suddenly disappeared? A recent survey has shown that     1     number of people in the United Kingdom who do not want to use the Internet has risen. These people, who     2     (know) as “net refuseniks”,make up 44% of UK households, or 11.2 million people in number.

The research also showed that more than 70 percent of these people said that they were not     3     (interest) in getting connected to the Internet. This number has risen     4     just over 50% in 2005 to the present 70% , with most lacking in many computer     5     (skill) as a reason for not using the Internet, though some also said it was because of the cost.

More and more people are getting broadband(宽带) and high speed net     6     (be) almost everywhere in the UK, but there are still a lot of people who refuse     7     (take) the first step.

With the cost of getting online going down and internet speeds increasing, many net refuseniks begin to reconsider the     8     (connect) of the Internet. This would encourage them to get connected before they are left too far behind. If the gap(落差) between those     9     use the Internet and those don’t continues to widen, those without broadband will get left behind and miss many chances,     10     (especial) in their work.
