One hot night last August, I tried everything I could think of — toys, songs etc. to make him fall into sleep, but he just couldn't do it. Since I believed that a long night was waiting for me ahead, I had no choice but to bring a TV into his room to kill off the hours until dawn. I was surprised that the moment I turned on the TV the baby became quiet right away and fixed his little eyes brightly on the screen. Not willing to waste an opportunity for sleep, I then tiptoed(蹑手蹑脚地行进) out of the room, leaving him to watch the boring TV programs. I heard no more of the baby's crying that night and the next morning when I went into his room, I found him still watching TV by himself. I found there was a metaphor(暗喻) in my baby's behavior(行为) for the new generation. When I gave my boy some books to go over, he only spit upon them; when I read to him, he did not feel comfortable. And so it is in the schools with my students. I find that our students don't read and they look down upon reading and make light of those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have drawn a conclusion: “Let them watch it!” If television is that much more attractive to children than books, why should we fight against it? Let them watch what they want！

    Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses（球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements（代替物）for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    Last week, my granddaughter started kindergarten, and I wished her every success. But part of me didn't. I actually wanted her to fail in some ways because I believe that failure can be good for our learning process. Success is proving that you can do something that you already know you can do, or doing something correctly the first time, which can often be a problematic (存在问题的) victory. First-time success is usually a fluke (侥幸). First-time failure, however, is supposed to be the natural order of things. Failure is how we learn.

    In Africa they describe a good cook as “She who has broken many pots.” If you've spent enough time in the kitchen to have broken a lot of pots, probably you know a fair amount about cooking. I once had dinner with a group of cooks, and they spent time comparing knife wounds and burn scars. They knew how much credibility (可信) their failures gave them.

    I earn my living by writing a daily newspaper column. Each week I know that one column I write is going to be the worst column. I try my best every day. I have learned to love that column. A successful column usually means that I am discussing my familiar topic, writing in a style I am used to or saying the same things as anyone else but in a better way.

    My younger daughter is a trapeze artist (荡秋千演员). She spent three years practising a show, and she did it successfully for years. There was no reason for her to change it but she did anyway. She said she was no longer learning anything new and she was bored. And if she was bored, there was no point in subjecting (使……服从于) her body to all that stress. She risked failure and great public embarrassment in order to feed her soul.

    My granddaughter is a perfectionist. She will feel her failures, and I will want to comfort her. But I will also, I hope, remind her of what she learned, and how she can do better next time. I hope I can tell her, though, that it's not the end of the world. Indeed, with luck, it is the beginning.

    For the past 15years, factory owner Kamal Parmar has been running an after-school program for slum kids in Ahmedabad, India, helping them with basic skills like reading and writing and even preparing for their school tests.

    Parmar's story began one afternoon 15 years ago. He stopped a few kids returning home from the local school and took their exam paper and asked them a few questions. Shockingly, he made a shocking discovery--the students, even the older ones, knew nothing about reading except the alphabet. And that left him thinking that something should be done for these children.

    So he invited the kids to visit his workshop every evening, where he set up a temporary classroom with metal desks. The shabby school started off with 10 students. Today, the Footpath School has a total of 155 students and many of the kids that Parmar has taught in the past 15yearshav e gone to attend college and build successful careers.

    Despite having studied only till the seventh grade, he has been able to teach the kids by inventing creative techniques. He asks them to read first and then to form questions on their own and read them out. In this way, many kids learn all seven subjects in six months.

    Parmar's family are very supportive of his project and are proud to see how much of an impact he has had on the kids. His students love him. Ten of his ex-students are currently serving as teachers at the school and he doesn't have to employ any teachers.

    For those who are inspired by his story, but can't actually volunteer at school, Parmar has a simple piece of ads ice: “Try to educate just one child a year, and see the difference it makes to the society.”

    Martha had been working for Miller Laboratories for two years, but she was not happy there. Nothing significant had happened in the way of promotions or salary increases. Martha felt that her supervisor, a younger and less experienced person than she, did not like her. In fact, the supervisor often said unpleasant things to her.

    One day, while talking with her friend Maria, she mentioned how discouraged she was. Maria gave her the name of a cousin of hers who was director of Human Resources Department for a large chemical company. Martha called him the next day and set up an interview on her lunch hour.

    During the interview, Mr. Petri said, "You're just the kind of person we need here. You're being wasted in your other job. Give me a call in a day or two. I'm sure we can find a place for you in our organization." Martha was so happy that she almost danced out of the building.

    That afternoon, Ruth Kenny, her supervisor, saw that Martha had come in ten minutes late from her lunch hour and she said, "Oh, so you finally decided to come back to work today?"

    This was the last straw. She could not take another insult. Besides, Mr. Petri was right: she was being wasted in this job.

    "Look," she said angrily, "if you don't like the way I work, I don't need to stay here. I'll go where I'm appreciated! Goodbye!" She took up her things and stormed out of the office.

    That night she called Maria and told her what had happened and then asked Maria, "What do you think?"

    "Well," said Maria carefully, "are you sure about the other job?"

    "Well, not exactly, but..."

    Maria continued, "Will you be able to get a recommendation from Ms. Kenny if you need one?"

    "A recommendation?…from Ms. Kenny?" hesitated Martha, in a worried tone.

    "Martha, I hope you didn't burn your bridges," Maria said. "I think I would have handled it differently."
