A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20%-40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboatories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

China is going green. In order to reduce air pollution and oil shortages, carmakers have announced their plans to develop hybrid vehicles (混合燃料汽车) for the Chinese market. Toyota’s hybrid car Prius will be ready to drive in China this week. Let’s have a look at the new car.
Any vehicle is a hybrid run on a rechargeable battery and gas. Hybrid cars have special engines, which are smaller than traditional gas engines. The gasoline engine provides 99 percent of the power when the car is going at a steady speed. A specially designed battery motor provides extra power for running up hills or when it needs to speed up.
Step into a Prius, and turn on the engine. The first thing you notice is that it is quieter than a traditional car. At this point, the car’s gas engine is at rest. The electric motor will provide power until the car reaches about 24km/h. If you stay at a low speed, you are effectively driving an electric car, with no gas being used, and no waste gas given off.
The computer decides when to use the gas engine, when to go electric, and when to use a combination of the two. If you go over 24km/h, when you step on the gas pedal (油门), you are telling the computer how fast you want to go.
The electric motor recharges automatically using a set of batteries. And when driving at a high speed, the gas engine not only powers the car but also recharges the batteries. When you use the brake, the electric motor in the wheels will work like a generator (发电机) to produce electricity to recharge the batteries. As a result, the car’s batteries will last for around 200,000 miles.

【推荐2】When John Todd was a child, he loved to explore the woods around his house, observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be used to clean up the messes people were making.
After studying agriculture, medicine, and fisheries in college, John went back to observing nature and asking questions. Why can certain plants trap harmful bacteria (细菌)? Which kinds of fish can eat cancer-causing chemicals? With the right combination of animals and plants, he figured, maybe he could clean up waste the way nature did. He decided to build what he would later call an eco-machine.
The task John set for himself was to remove harmful substances from some sludge (污泥). First, he constructed a series of clear fiberglass tanks connected to each other. Then he went around to local ponds and streams and brought back some plants and animals. He placed them in the tanks and waited. Little by little, these different kinds of life got used to one another and formed their own ecosystem. After a few weeks, John added the sludge.
He was amazed at the results. The plants and animals in the eco-machine took the sludge as food and began to eat it! Within weeks, it had all been digested, and all that was left was pure water.
Over the years, John has taken on many big jobs. He developed a greenhouse — like facility that treated sewage (污水) from 1,600 homes in South Burlington. He also designed an eco-machine to clean canal water in Fuzhou, a city in southeast China.
“Ecological design” is the name John gives to what he does. “Life on Earth is kind of a box of spare parts for the inventor,” he says. “You put organisms in new relationships and observe what’s happening. Then you let these new systems develop their own ways to self-repair.”
1. What can we learn about John from the first two paragraphs?A.He was fond of traveling. | B.He enjoyed being alone. |
C.He had an inquiring mind. | D.He longed to be a doctor. |
A.To feed the animals. | B.To build an ecosystem. |
C.To protect the plants. | D.To test the eco-machine. |
【推荐3】Sunglasses that can record videos
Snapchat, the popular social media app that allows users to share photos or short videos, or “snaps”, has taken the world by storm since its launch in 2011. Now, the company has done it again with the release of Snapchat Spectacles-stylish sunglasses that can record short videos.
To begin recording, the user taps a button on the left hand comer of the sunglasses. However, the camera can only record a 10-second-long video at a time.
The recording can be instantly downloaded to an Android phone or iPhone via Bluetooth or Wi-Fi and shared with friends and family through the Snapchat app. If a user does not have access to a phone, the film remains stored in the sunglasses.
To recharge the camera’s battery, the user simply places the Spectacles back into the bright yellow sunglasses case that comes with the purchase. What’s great is that the portable case can store enough power to charge the sunglasses up to four times, before the case itself needs recharging.
The Snapchat Spectacles, which were released on November 10, 2016, are priced at $ 130. While not cheap, they are a bargain when compared to Google Glasses, which cost $ 1, 500. But before you rush out to get yourself a pair, be warned that they are a little hard to find. For the past few weeks, the Snapchat Spectacles could only be bought in select American cities with limited stock.
On November 21, the company established its first semi-permanent storefront in New York City. Those wishing to obtain a pair or two (the maximum allowed) have to be prepared for a long wait. Judging from the over 500 people that patiently lined up outside the store long before it opened, Snapchat Spectacles’ fans do not appear to mind! Most probably the glasses will rank high on Christmas wish lists this year.

Robots have arrived in American restaurants and hotels for the same reasons they first arrived on factory floors.
“We think we’ve hit the point where labor-wage rates are now making automation of those tasks make a lot more sense,” Bob Wright, the chief operations officer of the fast-food chain Wendy’s, said in a conference call with investors last February, referring to jobs that feature “repetitive production tasks.” Wendy’s and McDonald’s are in the process of installing self-service kiosks in locations across the country, allowing customers to order without ever talking to an employee.
How many employees, though, do you need working in the café?
The experience of Eatsa may be instructive. The start-up restaurant, based in San Francisco, allows customers to order its quinoa bowls and salads on their smartphone or an in-store tablet and then pick up their order from a white wall of cubbies — an Automat for the app age. Initially, two greeters were stationed alongside the cubbies to welcome and direct customers.
A.The early success of the kiosks suggests that, at least when ordering fast food, customers prize speed over high-touch customer service. |
B.Business owners insist that robots will take over work that is dirty, dangerous, or just dull, enabling humans to focus on other tasks. |
C.The better hope for workers might be that automation helps the food-service industry continue to develop. |
D.But over time, customers relied less frequently on the greeters. |
E.The cost of machines has fallen significantly in recent years, dropping 40 percent since 2005. |
F.This has typically been the story of automation: Technology eliminates old jobs, but it also creates new ones. |
【推荐2】The rapid growth in skyscrapers worldwide, most of which have large windows, has led to a high demand for window washers. Though the job is well-paid, it is dangerous and accidents are not uncommon. However, if Israel-based start-up Skyline Technologies has its way, the dangerous job may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising from the safety of the ground.
Much like humans, Ozmo, sitting on platforms hanging from the buildings, uses its arms and brushes to clean the dirt on the glass. A 3D map of the building’s surface programmed into its system allows the robot to skillfully deal with any obstacle it is likely to meet, as it moves up and down the buildings. The robot will self-correct and move around every obstacle that it might have met so as not to break a window.
Unlike present window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled(蒸馏的)water to do the job. Yaron Schwarcz, CEO of Skyline Robotics explains, “We are environmentally friendly.” Ozmo is also expected to be much more efficient than its human counterparts. While it presently takes three cleaners 480 hours each to clean windows of a 40-storey glass building, the robot will be able to do it in 80 hours. However, unlike other robots, Ozmo will not replace human workers, and only make their jobs safer by making them supervisors, who will be controlling the operation from the safety of the ground.
Whether Ozmo, which is still being tested, does as good a job as humans is not clear. If things go well, its creators have much bigger ambitions for Ozmo. Schwarcz told Forbes Magazine, “Window cleaning is just the tip of the iceberg. We plan to replace all tasks that are dangerous and dirty.”

【推荐3】Accompanied by the background sounds of Chinese traditional instruments, Yuanxi — China Daily’s digital employee — introduced the 9,000-year-old stone carvings (岩画) from the Helan Mountains in Northwest China’s Ningxia Hui autonomous region on Oct 14.
The meeting between the virtual human and Chinese traditional culture is quite interesting,” an internet user commented on Sina Weibo.
With the rise of the metaverse (元宇宙), virtual humans have become a growing phenomenon in China. According to a research report by QbitAI, it is estimated that the overall market size of China’s virtual humans will reach 270 billion yuan by 2030.
Though they are not real, these virtual beings share similar identities with us and serve in different fields of our daily lives, including education, broadcasting, and business. For example, in June 2021, Hua Zhibing, a virtual human who can write poetry, was officially registered as a student at Tsinghua University. Throughout the 2022 Winter Olympics, China’s first AI sign language presenter served hearing-impaired (有听力障碍的) audiences 24/7.
Due to their perfect image and interesting setups, some virtual humans even get a large number of fans and become idols in real life. Luo Tianyi is one of them. As a virtual singer, Luo has over 5 million followers on Sina Weibo. When she held a concert in Shanghai in 2018, more than 10,000 fans waved glow sticks and cheered for her. Gao Yu, a fan of Luo, told Economic Information Daily that “just like chasing human idols, Luo’s fans also hold birthday parties for her and buy the products she promotes.”
While the future of virtual humans seems promising, problems also lurk (隐藏着) underneath. As the novelty wears off, some followers are getting tired of virtual humans’ never-changing expressions. “No matter how lifelike these virtual influencers look, they’re still not real people. It’s a little scary,” Gigi You, 23, from Guangdong, told Insider. Studies also showed that their “perfect” face and “perfect” life which humans are unable to achieve can also trigger (引发) anxiety and depression in individuals.
Generally speaking, virtual humans are often seen as the gateway to the metaverse and have demonstrated financial potential, but there’s still a lot of room for development, reported Xinhua.

But instincts and training aren’t the only keys to animals’ behavior. Scientists say animals’ thoughts and feelings also influence their actions. Animals often make choices, plans, and sensible changes. They can help others and solve problems. Some even make and use tools!
If animals could talk, what would they say about their thoughts and feelings? A gorilla (大猩猩) born in captivity (关在笼子里) has helped answer that question. Koko, a gorilla, was taught to use sign language. She has learned hundreds of words!
Koko once had a pet cat she named All Ball. “Koko love Ball,” she signed. “Soft good cat.” One time, she blamed the cat for biting her by signing “You bad dirty toilet!” When her pet died, Koko cried. “Sad for sleeping cat,” she signed.
Koko calls herself “fine animal gorilla”. She uses sign language to argue, joke, and ask and answer questions.
“Most animals can’t use words to tell us their thoughts,” says Dr. Jonathan Balcombe. “But Koko shows us that animals have their own ideas and feelings.” Dr. Balcombe is a scientist at the Humane Society of the United States. He says there’s even more to discover about animals through field studies. In field studies, people watch animals in their natural environment.
“Scientists who study animals’ natural behaviors learn how animals live and think,” Balcombe says. “That knowledge can help others respect every animal who shares the planet with us.”

【推荐2】Getting Around on Campus
Thanks to the sunny weather and wide campus, bicycles are one of the most popular means of transportation at Stanford. There are over 12,000 bikes on campus, as well as the full service Campus Bike Shop at Tresidder Union.
To make it safer for walkers and cyclists, the University has designed the center of campus a pedestrian zone; four wheeled vehicles are not allowed. You can ride your bike anywhere on the Stanford campus except in the arcades(拱廊) around the Main Quad, which are reserved for foot traffic.
Some Things to Keep in Mind.
·Register your bike. Whether you purchase a bicycle at Stanford or bring one from home, you must register it with Santa Clara County. You can register your bike:
1. During registration events in White Plaza during New Student Orientation;
2. Online at Parking and Transportation Services (P&TS) website.
·Buy a bicycle lock such as a Kryptonite U-lock and a six-foot cable or chain. Bicycle theft is the most common campus crime, and most bikes that are stolen are locked with easy-to-cut cables. If you lose your bike lock key, call the Campus Bike Shop at (650) 723-9300 to have the lock cut for a fee.
·Park your bike in designed spaces. Be sure not to block a pathway, building entrance, or ramp intended for use by people with disabilities. The Department of Public Safety may remove and impound improperly parked bikes.
·Use a bike light if you are riding at night, and you are advised to wear a helmet at all times. P&TS gives out free bike lights during registration events; the Campus Bike Shop sells highquality helmets for $20.
·Follow traffic laws. Bicyclists are expected to obey the same traffic laws as automobile drivers and may be ticketed if they do not. To avoid a ticket, stop at all stop signs, ride in the direction of traffic, and use the same turn lanes as other drivers. The Bicycling Information section of the P&TS website has additional information on biking at Stanford, including bicycle route maps. You also can learn more about Bicycle Rules and Safety at the California Department of Motor Vehicles website.
