Apple is to open a research lab in the southern Chinese city of Shenzhen, according to Tim Cook, its chief executive, as it seeks to boost sales in the country and improve ties with the authorities.

    Beijing has been encouraging foreign technology companies to carry out more high-end work on the mainland as part of efforts to revitalize local industry.

    It will be Apple's second facility in China. It already has a new research and development facility in Beijing.

    The two R&D centers were “aimed at strengthening relationships with local partners and universities as we work to support talent development across the country”, Apple said in a statement.

    A closer relationship with the Chinese authorities has been a priority following setbacks for the US technology company this year.

    The iPhone has been losing market share to high-end handsets made by local competitors including Huawei, Vivo and Oppo, which topped the rankings in the second quarter, while Apple languished in fifth place, according to Canalys data.

    Analysts said the announcement of the R&D centre was Mr. Cook's latest attempt to gain favour with Beijing, following the US group's $1billion investment in Didi Chuxing, the Chinese car-hailing company, in May.

    Apple has had to change its approach in China as it faces rising nationalism and high-quality local competition, according to Ge Jia, a tech blogger, who wrote yesterday: “It's time for Apple to cast aside their pride.” “Their previous strategy of only selling devices to China without leaving anything behind is not working any more and they are starting their process of localisation in China through the Shenzhen lab.”

    It was the day after Halloween when my grandmother was admitted to the hospital with the worst headache she'd ever had. While posing in our costumes the night before, we knew something was wrong, just not how wrong.

    Grandma's house was the central gathering place of my family. Sunday lunches, birthday dinners, Easter, Thanksgiving, and Christmas — all were our traditions, with her as hostess. While my parents were busy running their small business, there were many nights when Grandma fed me and put me to bed in her spare room, until they came to get me. I spent my summers at Grandma's and I went everywhere with her. I couldn't imagine a time when she wouldn't be around me.

    Then November 1,1991 began her month-long stay in the hospital—she suffered from a rare infection (感染)called nocardia asteroides. After being born in the year of the Great Depression, living through World War II, raising three kids, and being widowed at the age of 48, Grandma never expected to live into her seventies. The infection in her brain seemed to confirm that she wasn't long for this world. But that's not the end of her story. A team of doctors successfully removed the abscess(脓肿), and Grandma even made it into a local medical journal. Her doctor called her “the brain lady”.

    Grandma celebrated her 85^th birthday in March this year. In the almost 23 years since her recovery, she's seen two of her four grandchildren get married and welcomed three great-grandsons. Although they damage something in her house, she loves it when my two boys come over. And while I know they make her day, seeing her love blossom for another generation makes my day too. Happy Grandparents' Day to my amazing grandmother!

    Summer time is a great opportunity for kids to learn how to work and earn a little bit of spending money. If your child needs a summer job, here are a few options to consider:

Lemonade/Cookie Stand

Benefits

    Creates a concept of running a business: Your child will be his own boss, set his own price , and run the show. It's a great introduction to running his own business.

    Limited Start-Up Costs: The things used to make lemonade are cheap, so your child should be able to get back his investment with a handful of sales.

    What Kids Learn About Money: Your child will learn a very valuable lesson about pricing. The price of his lemonade will decide how much he can sell, if he will recover his investment and the amount of profit.

Yard Work

Benefits:

    Repeated Customers: If a homeowner needs help raking (耙地) this year, he'll probably want help again next year. Your child should be able to maintain a regular set of customers after one season.

    Safety: Yard work is generally safer than a lawn-mowing job. Without having to operate machines, your child will be much safer.

    What Kids Learn About Money: Because of the variability (变动) in pay, your child will need to learn how to negotiate(谈判) a fair price with homeowners if they ask.

Lifeguard

Benefits:

    Responsibility: Kids learn a lot about responsibility when lifeguarding. They are within rights to tell whether a certain activity is safe and are allowed to take action as they see fit.

    Exercise: Lifeguards need to be proficient at swimming and must exercise to stay in shape.

    What Kids Learn About Money: To be a lifeguard, one must be certified. Your child may have to pay for lifeguard training, although some employers provide it on-site.

    In my living room, there is a plaque (匾) that advises me to “Bloom (开花) where you are planted.” It reminds me of Dorothy. I got to know Dorothy in the early 1980s, when I was teaching Early Childhood Development through a program with Union College in Barbourville, Kentucky. The job responsibilities required occasional visits to the classroom of each teacher in the program. Dorothy stands out in my memory as one who “bloomed” in her remote area.

    Dorothy taught in a school In Harlan County, Kentucky, Appalachian Mountain area. To get to her school from the town of Harlan, I followed a road winding around the mountain. In the eight-mile journey, I crossed the same railroad track five times, giving the possibility of getting caught by the same train five times. Rather than feeling excited by this drive through the mountains, I found it depressing. The poverty level was shocking and the small shabby houses gave me the greatest feeling of hopelessness.

    From the moment of my arrival at the little school, all gloom (忧郁) disappeared. Upon arriving at Dorothy's classroom. I was greeted with smiling faces and treated like a queen. The children had been prepared to show me their latest projects. Dorothy told me with a big smile that they were serving poke greens salad and cornbread for “dinner” (lunch). In case you don't know, poke greens are a weed-type plant that grows wild, especially on poor ground.

    Dorothy never ran out of reports of exciting activities of her students. Her enthusiasm never cooled down. When it came time to sit for the testing and interviewing required to receive her Child Development Associate Certification, Dorothy was ready. She came to the assessment and passed in all areas. Afterward, she invited me to the one-and-only steak house in the area to celebrate her victory, as if she had received her Ph. D. degree. After the meal, she placed a little box containing an old pen in my hand. She said it was a family heirloom (传家宝), but to me it is a treasured symbol of appreciation and pride that cannot be matched with things.  (360 words)

Humans have sailed the oceans' surfaces for millennia（千年）, but their depths remain effectively uncharted. Only about a quarter of the seafloor has been mapped at high resolution. Maps of most regions display only approximate depths and often miss entire underwater mountains or canyons（峡谷）.

So a group of researchers has recruited some deep-diving experts: Elephant Seals and Weddell Seals. Scientists have been placing trackers on these blubbery marine mammals around Antarctica for years, gathering data on ocean temperature and salinity. For a new study, the researchers compared these dives' location and depth data with some of the less detailed seafloor maps. They spotted places where the seals dove deeper than should have been possible according to the maps--meaning the existing depth estimates were inaccurate.

In eastern Antarctica's Vincennes Bay, the diving seals helped the scientists find a large, hidden underwater canyon. An Australian research ship called the RSV Nuyina later measured the canyon's exact depth using sonar, and the researchers have proposed naming their find the Mirounga-Nuyina Canyon—honoring both the ship and the involved Elephant Seals, genus（动植物的属）Mirounga.

But seals can't map the entire ocean floor. The trackers used in the study could pinpoint a seal's geographical location only within about 

1.5miles. Plus, because the seals don't always dive to the bottom of the ocean, they can reveal only where the bottom is deeper than in existing maps—not shallower. McMahon notes that scientists could improve on these data by using more precise GPS trackers and analyzing the seals' diving patterns to determine whether they have reached the seafloor or simply stopped descending.

The current seal-dive data can still be valuable for an important task, says Anna Wåhlin, an oceanographer. The deep ocean around Antarctica is warmer than the frigid waters at the surface, and seafloor canyons can allow that warmer water to flow to the ice along the continent's coast, Wåhlin explains. To predict how Antarctica's ice will melt, scientists will need to know where those canyons are and how deep they go.
