Chinese e-commerce websites fail to pay more attention to older consumers, says a news report.

    There's been a thought that younger consumers have been the driving force of online buying. That may not be the case. According to a statement from Alipay, the average expenditure (支出) of Alipayusers born before the 1960s was 31,000 yuan in 2012, much higher than 14,000 yuan of those born after the 1980s. It shows that online shopping has become akey part of people's daily consumption, for both young and old.

    Besides shopping, people pay bills such as water bill, electricity bill, and credit card repayment online. The middle-aged and senior consumers are also participating in that consumption revolution.

    Liu Chen, 56, said that his online expenditure in 2014 was over 50,000 yuan, about half of the total annual expenditure. He always pays his telephone bill online. Clothes, electrical appliances and kids' snacks are themain items he purchases online.

    Liu's shopping strategy is to find something good online first, then go to shops to check it out, and finally buy it online because it is cheaper. As quality concerns him, Liu only buys items that come with aguarantee.

    Stories such as those from Liu are representative of millions of middle-aged and older Chinese, which show the great potential of the aged inthe Chinese consumption market. Yet, the market seems not to be valued as it should be.

    Some Chinese e-commerce websites such as jd. com, dangdang. comand amazon. cn don't have a category for goods for the elderly on their mainpages. Alibaba's platform does have one, but the goods in it are not as abundant as other categories. Moreover, Taobao's category is not really designed for elders, but their children.

    Despite the seeming lack of commitment to older consumers, the Chinese market for the elderly is clearly huge, and e-commerce websites should takegreat efforts to develop it.

    Recently some articles claims the word "selfie" as one of the most annoying words. But I'd like to offer that maybe it is not so bad.

    The “selfie” is used to describe the self-taken photo, often from a smart phone. Women and men decorate their Facebook, Twitter, and Instagram accounts with these pictures, sometimes with puckered (翘起) lips or large smiles. In fact, the selfie has become so widely known that over 31 million photos on Instagram are taken with the selfie.

    Let's think about it. Someone takes about 10 selfies each time they do, and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn't that beautiful? In that one picture, someone has given himself or herself confidence. Self-image is important. In society today, we are often so consumed with the feeling that what society tells us is perfect. But maybe, with that one selfie, we feel that we fit that bill. We feel handsome, beautiful, confident, smart, happy and content. For that moment, everything bad or terrible that has ever happened to us is erased (消除), because that smile or that pucker is what gives us the determination to love ourselves.

    I saw a spoken word poem recently and the young man said: If I ask you what you love, the answers will most likely roll off your tongue. You love to read. You love to write. You love birds, music, your mom, your brother, your sister, your daughter, your best friend, your dog. How long do you think you can go on and on before you say “I love myself”.

    That statement hit me like a ton of bricks. I've struggled with confidence all of my life. I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However, the selfie does deserve some credit for allowing individuals to express themselves. Pamela Rutledge agrees, stating, “There are many more photographs available now of real people than models.”

    Half an hour into a cooking competition at Green Street Academy, Tyana Givens, 15, dipped a plastic spoon into a pot with tomatoes, bell peppers, onions, garlic and mushrooms over a burner in a science classroom. She and the two other students, Kalimah Ball and Maya Smith, were making meat sauce.

    The girls had spent the past five weeks learning how to grow their own produce using food computers-tabletop greenhouses controlled by computer programs-at Green Street Academy, a charter school in Baltimore. The course, which weaved together lessons on programming, food systems and agriculture, ended with an “Iron Chef”-style cooking contest.

    With the help of instructor Melanie Shimano, the girls finished their contest successfully using the food they planted in tabletop greenhouses. The tabletop greenhouses can control temperature, light and water inside using the computer code that the students wrote by themselves. Shimano, a 26-year-old entrepreneur, piloted(试行)the course as part of Green Street Academy's junior biotechnology class in the spring and will expand the program to other schools in the fall.

    “Technology is not something that a lot of teachers have a lot of resources for all the time, but it's something that's not difficult to do with a relatively low amount of funding,” Shimano said. “Baltimore is a center for startups and food, so kind of fostering that culture of being into technology and into design and seeing all the pieces fit together is really cool.”

    While her course is unique to Baltimore, it's part of a broader program born at the Massachusetts Institute of Technology's Media Lab called the Open Agriculture Initiative, or OpenAg, which aims to create inventive, sustainable food systems through open-source technology. In addition to 10 full-time staff and researchers, OpenAg is primarily an online community of about 1,400 educators, growers, chefs and retailers in 47 countries, according to Hildreth England, OpenAg's assistant director.

    “The interest level across the board generally comes from folks who are concerned about food systems and concerned about the environment, and it's usually a combination of the two,” England said.

    Everybody hates rats (big mice). But in the earthquake capitals of the world — Japan, Los Angeles, Turkey — rats will soon be man's best friends.

    What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can't get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.

    How does it work? First, the rat is trained to smell people. When this happens, the rat's brain gives a signal (信号)．This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat's brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.

    Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, "Robots' noses don't work well when there are other smells around. Rats are good at that." Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don't need electricity!

    The "rat project" is not finished, but Julie Ryan of International Rescue Organization in Scotland says, "It would be wonderful. A rat could get into spaces we couldn't get to, and a rat would get out if it wasn't safe." Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

    I grew to be a tall girl but I tried to be as ordinary as possible. At school, I always chose a seat in the back of the room, and never raised my hand in class. When I was 16, I went to my new school. And I liked the English teacher. In my last year in high school, however, we were told that a new English teacher, Oliver Bascom, was going to teach us.

    Oliver Bascom! The girls laughed as we imagined a short and bald（秃头的）man．The situation was not funny, because this man would teach us for the whole year. Surprisingly, after we opened the door, there in front of the blackboard, we saw a young and handsome man!

    What followed was chaos, seventeen-year-old girls flying to get to seats in the front of the room. And I managed to get a front and center desk.

    I really wanted to make a good impression on my new teacher, but I usually kept quiet. The day that directions were given for our first major writing assignment, I arrived late to class. A friend later gave me the guidelines and I thought I understood them. I worked the whole weekend on the essay and waited nervously for Mr. Bascom's evaluation.

After three days, he arrived in class holding the corrected papers. "I've chosen the ten best essays for class discussion." he said.

    Twenty minutes later, my heart sank when he got to the last essay, and I didn't hear my name.

"These are all great essays," Mr. Bascom continued. "However, I am now going to read you the most successful of all…" We were all surprised as I was the author of this unusual work. A different girl walked out of the classroom that day. I knew that I had a new set of standards to live up to and that anything was possible in the future. Finally, I raised my head.
