【推荐3】“Digital native(数字土著)" is used to describe the generation of people who grow up at the age of technology, including computers and the Internet.

The idea of "digital native" came from an article to explain Prensky’s opinion on why today's teachers are having trouble teaching their students. Prensky says that young people today are speaking a digital language, while teachers are speaking an old language—they don't adapt themselves to the new technology. As a result, Prensky calls for a change in their teaching ways.

Digital natives are comfortable with technology and computers, and they consider technology to be a basic and necessary part of their life. Most teenagers and children in developed countries are digital natives because they mainly communicate and learn through computers, social networking services and texting.

Prensky's research shows that those who have all their life open to modern information technologies do really think, learn and understand the world differently from their fathers. Based on his own experience in working with students and educators, Prensky later created a concept that he calls “digital wisdom” to change the way to teach the digital students.

While the idea of digital natives has become popular among educators and parents, in business the digital natives were considered as a new and possible way to increase marketing. Many strategies have set out to catch the attention of digital natives to sell new goods. In recent years, more and more money has been earned from digital natives. And in the future, digital natives promise a bigger and bigger market.

【推荐1】Portia Maves rang the bell three times, signaling the end of a struggle and the start of a new chapter in her life.

“When you have your last treatment of chemotherapy (化疗) and are cancer-free, you ring a bell three times, ” said Portia, who reached that milestone on July 5, 2018 at Mayo Clinic Health System. “I was so excited to ring that bell. I had been going to treatments every three weeks for a year.”

Less than two months later, Portia became a student at Chippewa Valley Technical College (CVTC). A little more than a year later, she graduated into a new career as a motorcycle mechanic, fulfilling a lifelong dream. Portia was chosen as the student speaker for CVTC’ s summer graduation ceremony Thursday, August 1.

“My parents always wanted me to go to college right out of high school, but my mom didn’t want me to go into a profession that’s hard on the body,” said Portia. Although Portia had already developed a love of motorcycles, she understood her mom’s message. So Portia chose CVTC’s Nursing-Associate Degree program. After getting married and having children, Portia worked night shifts at a nursing home to help support her family.

“When my youngest child was 6, I was diagnosed with breast cancer,” Portia said. “I had surgery and went through a year of chemotherapy. Cancer made me realize you only live one time, and you have to do what you love to do. When I finished my chemotherapy, I said to my husband, ‘you know, I’ve always dreamed of being a motorcycle mechanic.’”

Her husband Jim Maves gave Portia his full support to go back to CVTC and fulfill her dream. She applied right away and started the program a few weeks later on August 20, 2018. She finished with a perfect 4. 0 grade point average.

Portia is already working in the parts department of the Harley-Davidson dealership in Chippewa Falls. Someday she hopes to go to Milwaukee for further training at company headquarters.

【推荐2】‘‘He’ll be over in a minute,’’ one of Saul Klein’s colleagues says apologetically, glancing towards a row of glass rooms where figures can be seen deep in conversation. One minute turns into two and then five, and then ten. Finally, Klein bounds over, saying, “Right, shall we start?”

Klein is the kind of person you can imagine this happens a lot. Not because he’s rude or forgetful or unreliable. In fact, he’s not any of those things.

The Johannesburg-born Klein is an entrepreneur (企业家), often spoken about as the brains behind Lovefilm and an early employee at Skype, but his CV (简历) goes beyond that.

For now, he says, the majority of his time is taken up with the companies LocalGlobe has invested in. “I’m involved on some level with all the companies in the portfolio (投资组合).” What that means in practice is that Klein attends regular meetings and extraordinary meetings where we meet with the companies”, and labs “when companies are coming up for important events like fundraising”. Oh, and on top of that, he’s also part of every company’s WhatsApp group— 200 groups to be precise.

“Time is nothing to him, so he’ll be replying to messages at 5 o'clock in the morning, “one of his assistants says. But Klein, a father of three children, aged 12, 11 and 4, says he actually tries to be “quite strict” with his time. “I’ve always tried not to do business at breakfast or dinner time. I try to be able to take the kids to school in the morning, and normally be at home for bedtime. Obviously as the kids get older they don’t want you around as much, but that’s not the case while they’re his age,” he says.

This routine isn’t just limited to mornings and evenings, Klein says. Ever since he started dating his wife, they both have practiced “lifestyle Shabbat”. “It basically means from a Friday night to a Saturday night, I’m not looking at emails, I’m not answering my phone, and I avoid driving. We’ve been doing that for almost 20 years at this point. I’ve always found that to be great relief.”

【推荐3】A ship that has spent decades trying to drill nearer to the earth’s mantle (地幔) is preparing for a new voyage to uncover clues to how life began.

With the plan to deepen a hole drilled nearly 20 years ago, two dozen geologists, microbiologists and other scientists will aboard the Joides Resolution to the Atlantis Massif. The hole won’t be the longest in the seafloor but would push closer than ever to the mantle and explore deeper layers of ocean crust (地壳) that haven’t been reached before. Engineers on the ship intend to lower heavy drilling tools through about 5,400 feet of water to find a hole on the seafloor about 15 inches wide. Joides engineers compared the process to standing on a chair and trying to lower a pencil tied to the end of string into the mouth of a soda bottle with a fan blowing.

Samples from the new depths will be taken to investigate whether a special mix of rock and water, Olivine, could have started life on Earth and possibly other planets. This green and magnesium-rich mineral, abundant at such depths, is critical to serpentinization (蛇纹石化), a reaction that occurs when some minerals encounter seawater. Geochemists think the process of serpentinization generates the energy and geochemical conditions favorable to the creation of organic molecules. “These are the building blocks of life,” said Susan Q. Lang, the expedition’s cochief scientist.

The new depth is thought where serpentinization occurs but where temperatures are beyond the limits at which life is known to exist. “If organic molecules are found there, it could help confirm that serpentinization leads to their creation, which contributed to the origin of life.” Dr. Lang said. Finding organic molecules in samples from serpentinization sites could also inform the search for life on other planets. “The geochemistry of fluids in the plumes of Enceladus, a moon of Saturn (土星), have been inferred by astrobiologists to be similar to the makeup of fluids found at the Atlantis Massif.” she added.
