    An autonomous vehicle designed for making local commerce deliveries was unveiled by Nuro. The vehicle is about the height of an SW but far narrower than a typical car. The electric car features four exterior compartments (暗格) — two on each side — to hold separate deliveries. Each compartment can be tailored to a specific use, such as cooking a pizza or refrigerating a package.

    “We can use self-driving technology to deliver anything, anytime, anywhere for basically all local goods and services,” Nuro co-founder Dave Ferguson said. “Consumers used to be okay with two-week paid shipping. It became two-week free delivery, followed by one week, two days, and the same day. Now same-day delivery isn't fast enough for some customers.”

    Nuro isn't alone in building robots for local commerce deliveries. Earlier this month, Toyota, a Japanese car company, unveiled a concept vehicle that could be used for package delivery. A handful of startups — including Starship Technologies, Marble and Dispatch — are testing small robots for deliveries on sidewalks.

    Nuro's vehicle will likely face legal hurdles. Fully autonomous vehicles without a test driver aren't legal in California today, and many companies have shifted testing to states where regulators are more welcoming of autonomous vehicles, such as Arizona.

    Nuro expects to face fewer challenges because it doesn't carry passengers. Nuro's narrow size may also be helpful when navigating streets and avoiding pedestrians. The vehicle isn't equipped with any special features to communicate with pedestrians or other road users. Some companies have tested and patented solutions such as digital screens that signal the car's next move. Ferguson said his team conducted studies and found that such techniques could confuse people. Nuro believes it's better to make sure the car performs predictably, so that human drivers know what to expect from it.

    “We feel by creating this new technology that's going to enable this last mile delivery, we're going to be creating new markets and doing things that previously weren't possible,” Ferguson said. “This is not swapping out Jobs with robots. It's creating new markets. There will definitely be new employment opportunities.”

    Scientists are trying to save Puerto Rico's endangered Amazon parrots after Hurricane Maria destroyed the birds' habitats and food sources(来源).

    El Yunque is a large national forest on the eastern part of Puerto Rico. Just two of the 56 wild parrots that once lived there survived Maria, the Category-4 storm that struck Puerto Rico in September 2017. Scientists report other forests have seen great drops in parrot populations as well.

    In the 1800s, there were more than a million of the bright green parrots living in the wild in Puerto Rico. By the 1970s, the number was down to just 13 birds after years of forest clearing.

    A special program was started in 1972 to help increase the parrot population, which led to the creation of three breeding(繁殖) centers. Just weeks before Hurricane Maria hit, scientists counted 56 wild parrots at El Yunque. That was the highest number in the program's history. Scientists say that even though several parrots have been born in captivity(笼养) and in the wild since Maria, the species is still in danger.

The Puerto Rican Amazon is the island's only remaining native parrot. More than 460 of the birds are kept inside the breeding centers at El Yunque and the Rio Abajo forest. Scientists have not released(释放) any of the birds since Hurricane Maria. A third breeding center, in a forest in the western area of Maricao, has not been in operation since the storm.

    Scientists are considering whether to catch some of the remaining wild parrots and put them in the same cage as the birds that are set to be released. This way, the captive birds can learn from the wild birds how to survive in the forests. Another consideration is to release some captive parrots in Maricao, which was not as heavily damaged by Maria.

    Just what is a tiger mother？Amy Chua is a law professor at America's Yale University and her recent book on the subject is making waves. She's been called "dangerous", "outrageous", even a "monster" for her descriptions of how she brought up her two daughters.

    Her book Battle Hymn of the Tiger Mother describes fighting with a daughter for hours at the piano to ensure the child gets a piece of music right. She rejected birthday cards made for her by her girls because she didn't think they had made enough effort. She compared one child negatively with the other, threatening to burn their toys. Her rules include：schoolwork always comes first; an A ­ minus is a bad grade; children must be two years ahead of their classmates in math, and playing the violin or the piano is a must.

    Ms. Chua considers the Chinese hard work ethic(道德) as a way of creating happy, successful children—at least in her case. Although she's had a large amount of flak for her theories, one thing can't be ignored—the success of Chinese children in the education system.

    In Britain, shocking research shows that Chinese girls, for example, are outperforming all other foreign groups at GCSE—79 percent getting 5 A ­ C Grades, compared with 58 percent of white British girls. So what is it about Chinese parenting that's leading to high achievers？And how do Amy Chua's theories play into that success?

    She told me that if her daughter came back from school with 96/100 in a test, Chua would ask her what happened to the other 4 points. It's about always knowing "you can do better", she told me.

    Interestingly, in China, the birthplace of the tiger mother, people are moving away from traditional Chinese parenting. They are following more western parenting styles.

Imagine a school where students are taught by the best teachers in every subject, regardless of location. Imagine a school where students could go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual(虚拟的)reality. 

Last year, Optima Academy Online, an all-virtual school, delivered courses that aim to improve the hearts and train the minds of young people. These courses are of different levels, attracting 170 full-time students from all over Florida. In the progress of home-schooling, students use headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins. 

Future versions(版本)of VR will doubtless be widely used in education, but the only questions are: for what purpose and at what speed? There are enough reasons to doubt whether VR schools represent the future of education. Sticking a child in their bedroom with a heavy VR headset fastened to their face and no physical social interaction with other kids will fill many of them and their parents with horror. 

A recent report concluded that digital education could significantly improve the quality and equality of schooling systems. But if managed poorly, it could have the opposite effect, turning a digital divide into an educational one. There is growing evidence to suggest that is happening. In Mexico, only 24 percent of 15-year-old students in poor schools have access(使用)to a home computer for schoolwork compared with 87 percent in rich ones. 

Used properly, technology can be great for enabling self-motivated students to access learning resources and connect with fellow students and teachers all over the world, says Beeban Kidron, a member of the UK's Digital Futures Commission. The trouble is that Edtech is too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a different way to learn, she adds. 

I was living in Sao Paulo, Brazil. It is a1 city, with more people living in it than in my whole country. We rented a flat in a guarded community, but there was a favela (棚户区) quite 2 .

For several months I didn't have a car, so three times a week, I took buses to go to the city centre. During these 3 , I would ride with the people who took the same bus from the favela to go to work. When I got on the bus, all the seats were already 4 . But when people saw that my bag was heavy, they offered to hold it on their legs to make me feel lighter5 . At first, I was 6 . Then I realized that these people had absolutely no 7 to steal from me: they only wanted to 8 .

Once, on my way back, I had to 9 for a long time at a bus stop. I was alone, except for a woman who was 10 very poor. She carried a small paper bag of popcorn and nothing else.

While we were waiting she walked over and 11 me some popcorn. I 12 her, but didn't want to help myself to it. She then repeatedly insisted that I take from what was clearly her only food.

That was the first time I had thought about how people who have almost nothing are sometimes able to 13 the little they have more "14 "than those who own a lot. I wonder if it's true that the more you have, the bigger the difficulty to share anything with others. I was so moved by that woman's simple generosity that day. I clearly 15 more than she did, but she naturally and joyfully shared what little she had with me.
