Some years ago, writing in my diary used to be a usual activity.I would return from school and spend the expected half hour recording the day'sevents, feelings, and impressions in my little blue diary. I did not reallyneed to express my emotions by way of words, but I gained a certainsatisfaction from seeing my experiences forever recorded on paper. After all,isn't accumulating memories a way of preserving the past?

When I was thirteen years old, I went on a long journey on footin a great valley, well equipped with pens, a diary, and a camera. During thetrip, I was busy recording every incident, name and place I came across. I feltproud to be spending my time productively, dutifully preserving for futuregenerations a detailed description of my travels. On my last night there, Iwandered out of my tent, diary in hand. The sky was clear and lit by the glareof the moon, and the walls of the valley looked threatening behind their screenof shadows. I automatically took out my pen...

At that point, I understood that nothing I wrote could evermatch or replace the few seconds I allowed myself to experience the dramaticbeauty of the valley. All I remembered of the previous few days were the dullcharacterizations I had set down in my diary.

Now, I only write in my diary when I need to write down aspecial thought or feeling. I still love to record ideas and quotations thatstrike me in books, or observations that are particularly meaningful. I takepictures, but not very often only of objects I find really beautiful. I'm nolonger blindly satisfied with having something to remember when I grow old. Irealize that life will simply pass me by if I stay behind the camera, busypreserving the present so as to live it in the future.

I don't want to wake up one day and have nothing but a pile ofpictures and notes. Maybe I won't have as many exact representations of peopleand places; maybe I'll forget certain facts, but at least the experiences willalways remain inside me. I don't live to make memories--I just live, and thememories form themselves.

    China is a land of bicycles．At least it was back in 1992 when I traveled the country．Back then everyone seemed to be riding a bicycle．Millions of them，all black．Cars were rare．Yet since my arrival in Beijing last year, I've found the opposite is true．There are millions of cars．However, people still use their bicycles to get around．For many, it's the easiest and cheapest way to travel today．Bicycles also come in different colors—silver, green, red, blue，yellow, whatever you want．

    It's fun people biking．They rush quickly through crossroads, move skillfully through traffic，and ride even on sidewalks．Bicycles allow people the freedom to move about that cars just can't provide．

    Eager to be part of this aspect of Chinese culture，I decided to buy a bicycle．Great weather accompanied my great buy．I immediately jumped up on my bicycle seat and started home．

    My first ride home was orderly．To be safe, I stayed with a“pack”of bikers while cars on the streets came running swiftly out of nowhere at times．I didn't want to get hit．So I took the ride carefully．

    Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States．The streets here were wide，so crossing took time，skill and a little bit of luck．

    I finally made it home．The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful．I was sitting on top of the world as I passed by places and people．Biking made me feel alive．

    Google is consistently rated the best place to work. So you need a degree from Harvard to in the door, right?

    Not really, according to Laszlo Bock, Google's Head of People Operations. When the company was small, Google cared a lot about getting kids from Harvard, Stanford, MIT and many other Ivy League schools.  But Bock said it was the "wrong" hiring strategy.  Experience has taught him there are exceptional kids at many other places, from state schools in California to New York.

    "What we find is the best people from places like that are just as good, if not better, as anybody you can get from any Ivy League school, "said Bock, who just authored a book titled "Work Rules!"

    Every year, 2 million people apply to get a job at Google.  Bock himself has seen some 25, 000 résumés.

    So what else does Google not care about:

    Grades: Google's data shows that grades predict performance for the first two years of a career, but do not matter after that.

    Brain-teasers: Gone are interview questions such as: Why are manhole covers（井盖)round? or How many golf balls can fit in a school bus? "Our research tells us those questions are a waste of time, "Bock said "They're a really coachable skill. The more you practice, you get better at it. "

    Here's what Google does care about:

    Problem solvers: Your cognitive ability(认知能力), or how well you solve problems.

    Leaders: The idea is not whether you were president of the student body or vice president of the bank, but rather:" When you see a problem do you step in, help solve it, "and then critically, "Are you willing to step out and let somebody else take over, and make room for somebody else? Are you willing to give up power?"

    Googleyness: That's what Google calls its cultural fit. It's not "Are you like us?" Bock said. "We actually look for people who are different, because diversity gives us great ideas."

    "What's most important is that people are intellectually humble, willing to admit when they're wrong, and care about the environment around them… because we want people who think like owners not employees, "Bock said.

    The least important thing? Knowing how to do the job.

    "We figure if you get the first three right you'll figure it out most of the time."

    You know eating fruit and vegetables is helpful. But did you know it can also make you look good?

    People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found.

    Scientists at St Andrews University found eating them subtly increased yellow and red pigments in the volunteers' skin.

    They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks.

    Increasing their intake of greens by 2.9 portions a day was found to make the person look healthier and an extra 3.3 portion could enhance their attractiveness, when their photographs were rated by others.

    Fruit and vegetables are rich in carotenoids（类胡萝卜素）, which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer.

    But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange, it was not known a small increase was perceptible to others and was seen as appealing.

    A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident at three weeks.

    Using light sensors, the researchers showed these red and yellow hues(色调，色相) were linked with the levels of carotenoids in their skin.

    There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene（番茄红素）which gives tomatoes and red peppers their red color - and beta-carotene found in carrots as well as broccoli, squash, and spinach.

    Skin color is also affected by chemicals called polyphenols(多酚), found in apples, blueberries and cherries, which cause blood rush to the skin surface.

    Right now, I am looking at a shelf full of relics, a collection of has-beens, old-timers, antiques, fossils. Right now, I am looking at a shelf full of books. Yes, that's right. If you have some spare cash (the going rate is about $89) and you are looking to enhance your reading experience, then I highly suggest you consider purchasing an e-reader. E-readers are replacing the books of old and I welcome them with open arms (as you should).

    An e-reader is a device that allows you to read e-books. An e-book is a book-length publication in digital form, consisting of text, images or both, and produced on, published through and readable on computers or other electronic devices. Sometimes the equivalent of a conventional printed book, e-books can also be born digital. The Oxford Dictionary of English defines the e-book as "an electronic version of a printed book", but e-books can and do exist without any printed equivalent.

    E-readers put printed books to shame. E-readers are superior to printed books because they save space, are environmentally friendly and provide helpful reading tips and tools that printed books do not.

    The average e-reader can store thousands of digital books, providing a genuine library at your fingertips. What is more, the e-reader itself is very small. It is easy to hold and can fit in a pocketbook or briefcase easily. This makes handling wooden giant such as War and Peace and Anna Karenina a breeze. Perhaps the only drawback to the space-saving aspect of an e-reader is that it requires you to find new things to put on your shelves.

    In addition, e-readers are environmentally friendly. The average novel is about 300 pages long. So, if a novel is printed 1000 times, it will use 300,000 pieces of paper. That's a lot of paper! And for the super bestsellers, these figures increase dramatically. For example, the Harry Potter book series has sold over 450 million copies. That's about 2 million trees! Upon viewing these figures, it is not hard to grasp the severe impact of printed books on the environment. Since e-readers use no trees, they represent a significant amount of preservation in terms of the environment and its resources.

    Finally, e-readers provide helpful reading tips and tools that printed books do not. The typical e-reader allows its user to adjust letter size, letterform and line spacing. It also allows highlighting and electronic bookmarking.

    Furthermore, it grants users the ability to get an overview of a book and then jump to a specific location based on that overview. While these are all nice features, perhaps the most helpful of all is the ability to get dictionary definitions at the touch of a finger. On even the most basic e-reader, users can find instant definitions without having to hunt through a physical dictionary.

    It can be seen that e-readers are superior to printed books. They save space, are environmentally friendly and provide helpful reading tips and tools that printed books do not. So what good are printed books? Well, they certainly make nice decorations.

    The Chinese invented paper in 105 A. D. They mixed the bark of a tree and rags (破布) with water, put a screen into the mixture, and lifted out a thin piece of wet paper. They dried the paper in the sun.

    The Chinese kept their secret of how to make paper until a war with Muslims in the ninth century. The art of papermaking soon spread throughout the Muslim world.

    The Mayan Indians in Central America and Pacific Islanders also discovered how to make paper, but their knowledge never spread to the rest of the world.

    For centuries, all paper was made by hand. Rags were the main material. Then a French scientist discovered that people could make paper from wood, too. Finally, in the eighteenth century, a Frenchman invented a machine to make paper from wood.
