We'd arrived at Rockefeller Center station on the D train. As in many of New York's underground stations, trains pull in at both sides of the platform. Or rather, they seem to erupt into the station first on one side, then on the other.

    Abruptly, my wife stopped.

“Uh, what's this?” she said.

    I looked over her shoulder. There at our feet lay a young woman of about 20. She was on her stomach with the top half of her body on the platform, while her legs hung over the tracks kicking powerlessly.

    She was stuck. She had also, clearly, been down on the tracks and discovered that climbing back up is really hard.

But unlike in our imaginings, this woman was not in panic, expecting her approaching death by the F train which would be screaming into the station in the next few minutes, if not seconds.

    She was laughing! So was her friend who half-heartedly leant down to assist. The assistance was somewhat weakened by the fact that the friend was holding her smartphone. Was she hoping to capture this moment with a picture? Or composing a text?

It's well known that people's compulsive checking of their phones can be deadly. Among young people in America, texting is now the number one cause of car crashes. Maybe it's also a leading cause of leaving friends to die when they fall in the river or on to the train tracks.

    I stepped forward, leant out as far as I could, got hold of her leg somewhere near the knee and, together with her finally-engaged friend, dragged the young woman on to the platform.

    And you can guess why she'd been on the tracks. Still laughing, but maybe chastened (内疚）by my look of horror she said, “Thanks. Sorry. My phone fell down there. ”

    While I turned to hold my daughter's hand and head upstairs, the young woman and her friend walked away. I wonder when she'll be scared.

    Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle — named the Transition — has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the air. It flies using a 23-gallon tank of gas and burns 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.

    Around 100 people have already put down a $10,000 deposit（定金） to get a Transition when they go on sale, and those numbers will rise after Terrafugia introduces the Transition to the public later this week at the New York Auto Show. But don't expect it to show up in too many driveways. It's expected to cost as much as $279,000. And it won't help if you're stuck in traffic. The car needs a runway.

    Inventors have been trying to make flying cars since the 1930s, according to Robert Mann, an airline industry expert. But Mann thinks Terrafugia has come closer than anyone to making the flying car a reality. The government has already permitted the company to use special materials to make it easier for the vehicle to fly. The Transition is now going through crash tests to make sure it meets federal safety standards.

    Mann said Terrafugia was helped by the Federal Aviation Administration's (联邦航空管理局) decision five years ago to create a separate set of standards for light sport aircraft, which are lower than those for pilots of larger planes. Terrafugia says an owner would need to pass a test and complete 20 hours of flying time to be able to fly the Transition, a requirement pilots would find relatively easy to meet.

    All people need to sleep. Sleep is a restorative(恢复健康的) process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.

    Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use the bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the possibility of your sleep being poor is rather high. Bedrooms should be designed, decorated and used for sleep only. TVs, computers and other things should not be in your bedroom if possible.

    Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before you go to bed. Develop a regular exercise program. Proper exercise and nutrition will help improve sleep patterns. However, avoid exercising 2 hours before bed, since this may stimulate your body and make it more difficult to fall asleep.

    Establish a pre-bedtime rule that will help you focus on sleep. You can try meditation(沉思), reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category. Do what is best for you.

    Things such as room temperature, noise and light levels and even your bed mattress(床垫) can have a lot of effect on the quality of sleep that you experience. Block out distracting noises and lights. You are in your bedroom to sleep and not be distracted by environmental interference(干扰).

    UK education is all about giving you inspiration to develop your knowledge and skills, freedom to be creative, and support to help you achieve your best.

    On a UK course you will benefit from excellent teaching and facilities. In order to accept students, UK education centres must meet strict quality standards set by the UK government and education bodies.

    With such a good reputation for research and education, universities and colleges in the UK attract some of the world's leading academics and professionals. You will be encouraged to express your own ideas and think for yourself.

    The attention to quality is reflected in the UK's excellent results:

    Four of the top six universities in the world are in the UK.

    The UK is a world-leading research nation. 54% of the research conducted by UK universities and colleges is classed as either "world-leading" or "internationally excellent".

    At the most recent inspection, 97% of further education colleges were judged satisfactory or better, for their overall effectiveness.

    In the recent BIS Tracking International Graduate Outcomes survey, more than 88% of international higher education graduates said they were satisfied with their UK learning experience.

    Likewise, in the Higher Education Academy Postgraduate Taught Experience Survey of UK postgraduate students, 93% rated the quality of teaching positively.

    For English language students, you'll find the UK has long been at the forefront of language teaching, and pioneered many of the techniques now used around the world. The emphasis is on learning the language through fun and participation: Instead of just listening to your teacher, your classes will involve games, problem-solving and discussions. You might also listen to songs, watch television or read magazines to practise your comprehension skills.

    The UK's boarding schools also offer excellent teaching, facilities and support. At UK independent schools (most boarding schools are independent), a teacher has just 9.4 pupils on average, so teachers have more time to give you individual support. This is reflected in the results: 91% of students from UK independent schools go on to higher education.

    About a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear this was a business call. "I want to apply to work with you at Facebook," she said. "Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?"

    My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook's needs front and center. It was a killer approach. I responded, "Recruiting is my biggest problem. And, yes, you can solve it."

    Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.

    The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: "Careers are a jungle gym, not a ladder."

    As Lori describes it, there's only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.

Hobbs was an orphan. He worked in a factory and every day he got a little money. Hard work made him thin and weak. He wanted to borrow a lot of money to learn to paint pictures, but he did not think he could pay off the debts.

One day a lawyer said to him, "One thousand dollars, and here is the money. "As Hobbs took the package of notes, he was very dumbfounded. He didn't know where the money came from and how to spend it. He said to himself, "I could go to find a hotel and live like a rich man for a few days; or I give up my work in the factory and do what I'd like to do: painting pictures. I could do that for a few weeks, but what would I do after that? I should have lost my place in the factory and have no money to live on. If it were a little less money, I would buy a new coat, or a radio, or give a dinner to my friends. If it were more, I could give up the work and pay for painting pictures. But it's too much for one and too little for the other."

"Here is the reading of your uncle's will," said the lawyer, "telling what is to be done with this money after his death. I must ask you to remember one point, Your uncle has said you must bring me a paper showing exactly what you did with his money, as soon as you have spent it. "

"Yes I see. I'll do that, "said the young man.
