3 . Engineers at Zhejiang University have created China's first brain-like computer, named Darwin Mouse, which can copy the way a human brain works and solve complex calculations while using a small amount of the energy used by traditional supercomputers.
Though the technology is still in its early stages, experts say it could be used to run large, real-time simulations(模拟) and make new discoveries in chemistry, medicine and neuroscience. It could also be used to revolutionise computer design, leading to more powerful and efficient artificial intelligence.
Pan Gang, a professor at the university's College of Computer Science and Technology, said neuromorphic(神经形态的) computing has been a focus of the international scientific and engineering communities for some time and is considered one of the key methods to overcome the major computing challenges for artificial intelligence. Darwin Mouse represented a "major milestone achievement" in China's brain-like computing technology.
In late 2018, the University of Manchester in the United Kingdom upgraded its neuromorphic supercomputer SpiNNaker to use a million processors, enabling it to perform 2 trillion actions a second. This allowed the machine to run extremely large-scale real-time simulations, such as modelling parts of the brain. Darwin Mouse uses significantly fewer processors thanks to the latest developments in brain-like chips made in China, allowing it to perform far better.
Another advantage is low energy costs. When information is transmitted, only neurons that receive and process the signals are activated, while other neurons stay asleep, similar to how a brain works. As a result, the energy consumption can be reduced to a small part of that of conventional supercomputers.
"We hope to keep evolving the Darwin series neuromorphic computer towards reaching human levels of intelligence, thus achieving more powerful artificial intelligence with significantly less energy use. It is hopeful that brain-like computers will make their way into our daily lives as the hardware and the software for the technology mature," Pan said.

6 . Ocean Park Hong Kong is one of Hong Kong’s great visitor attractions.
For public transport, we recommend taking the subway to Ocean Park Station. The transfer station for the Tsuen Wan Line (through Tsim Sha Tsui) and the Island Line (from Central Station) is Admiralty Station. Simply go 1 stop in about 20 minutes.
Hong Kong is fairly unique in the world because you can purchase a card that you can swipe (刷卡) to pay for subway and bus fares.
A.Go there when it isn’t busy. |
B.Large crowds of visitors arrive later in the morning. |
C.It’s a good place where you can do research into rare animals. |
D.Unlike other theme parks, this park isn’t for a profit business. |
E.However, taxis from Central are relatively quick and inexpensive. |
F.And you can add money as you wish and return the card to a station window for some money back. |
G.It can also be used to pay for many other things such as purchases at supermarkets, convenience stores and restaurants. |
7 . Playing video interactive games, and later computer games, has been a big part of people’s lives ever since the birth of Pong and gaming consoles (游戏机) in the early 1970s. But games have progressed steadily since those early days. Now online games are being played worldwide by people of all ages.
While many people tend to think of gamers as people who sit alone on their couches and anonymous to other players, the opposite is actually true according to the BBC. With the rise in popularity of games, people, especially for those in Generation Z, have built communities and friendships with their fellow players. These connections have become a social lifeline during these times of social distancing and lockdowns (活动限制).
While TV and Netflix help people pass the time, there is no interaction between people like the ones found in gaming and the amount of time people play has seriously increased during the COVID-19 pandemic (疫情). In fact, in the US, gamers are now playing an average of 6 hours and 46 minutes weekly. And the numbers keep going up.
Twitch, which is owned by Amazon, where people can watch other people play videogames in real time webcasts and can chat with other viewers, actually clocked 5 billion hours of viewed content in the second quarter of 2020. That was an 83 percent increase from 2019 and a new record. But this increase in gaming is about much more than just entertainment. “This isn’t just out of boredom but an inner desire to be social. New gaming capabilities allow people to communicate with one another virtually,” said Nigel Burmeister, vice president of Limelight Networks. That’s because humans are naturally social and human contacts are necessary for our mental health.
Rosemary “Nekkra” Kelley, a 25-year-old gamer, told USA Today that she’s spending a lot more time playing games because her work has been curtailed due to the cancellation of live events. In her extra time, she has been playing Pokémon Sword and Animal Crossings on her Nintendo Switch.

8 . Patagonia, a leading brand in outdoor clothing, is climbing a mountain in the clothing industry and reaching a new summit. Through several measures, the company inspires people to share, resell, repair, and recycle their clothes, producing less waste. Every second, about one garbage truck of used clothes is sent to the landfill (填埋区) or is burned. Patagonia is taking this alarming statistic seriously.
A few years ago, the fashion giant launched an independent online store called Worn Wear, which is a collection of refurbished (翻新的) clothing where customers resell their old clothes for cash or store credit and shop for second-hand goods. Now Patagonia is approaching a step further ― they are including a “buy used” option on their website, offering second-hand clothes alongside their newest designs.
The second-hand trend is here to stay. Other chains such as The North Face, Macy’s, Adidas, Burberry, and Made well have also accepted the new circular economy business model. Famous traditional retailers (零售商) are also becoming used clothing providers, and are transforming the way second-hand clothes are sold and sensed.
Even the most skeptical shoppers are now open to the idea of buying used quality items. As a result, it is no surprise that the total secondhand market is projected to grow to almost twice the size of fast fashion by 2029. Naturally, the most sustainable piece of clothing is the one that already exists. This “green” article of clothing doesn’t require using virgin (原始的) resources, it prevents used clothes from ending up in landfills, and it requires no plastic packaging.
According to a 2018 report by thredUP, buying a piece of used clothing extends its life on average by 2.2 years, which reduces its carbon, waste, and water footprint by 73 percent. So even though the development of innovative materials and processes in fashion seems promising, wearing second-hand clothes is the easiest and most immediate way to face the environmental challenges the fashion industry brings.
1. What does the author intend to tell us in Paragraph 3?A.The second-hand trend is more commonly accepted. |
B.Lots of second-hand clothes are of high quality. |
C.Traditional retailers have a role to play in reducing waste. |
D.Consumer attitudes towards second-hand clothes are changing. |
A.Skeptical. | B.Optimistic. |
C.Urgent. | D.Unclear. |
