A new library in Tianjin—Tianjin Binhai Public Library—recently became an online hit. The Daily Mail described it as the “world's ultimate (终极的) library”, while the word “breathtaking” was the choice of Newsweek magazine. One look at the library and you'll see why. With its futuristic (未来主义) design and walls loaded with books, it's the dream library of every book lover.

    But as the surprise continues, there's a burning question lying in the back of our minds: When physical bookstores are closing down one by one, what makes libraries safe from the wave of digitalization (数码化)? And do we really still need libraries now that we've got the Internet in our hands?

    Reporter Ian Clark has the answer. “Libraries are not declining in importance—people are simply changing the way they use them,” he wrote on the Guardian website.

    What Clark means is that libraries have shifted from simply being storehouses of books to a medium to help “bridge the gap between the haves and the have-nots” according to website Libraries Are Essential. Since not everyone can afford a smartphone, a tablet or an Internet connection, and not everyone has the know-how to search the Internet correctly and efficiently, it's public libraries that make sure that these resources and technologies are available to a larger group of people.

    "Nobody is trying to sell you anything in the library. There is no pressure to buy and there is no judgment of your choices/' Anne Goulding, a professor at Victoria University in New Zealand, wrote on the Newsroom website. “There are few other spaces that you can just 'be' without somebody questioning your presence or your motivation."

    In the near future, we may be using our eyes to operate our smart-phones and tablets, even when it comes to playing popular games like Fruit Ninja.

    The Gaze Group has been developing eye-controlled computer technology for nearly 20years. But those devices have been firstly designed to help those with disabilities, and are very expensive.

    “After a while, we figured out that probably the best way is to go for a mass-market way,”says Gaze's Sune Alstrup Johansen. “Where everybody would have this available.”

    Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.

    The technology works when combined with the computing device toward the user's face. After making sure of the user's eye movements, the technology is then able to easily find where a person's eyes are moving, and then allow the eyes to control a cursor (光标)

    “Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at, ”reads an explanation on the Eye Tribe site.

    There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Recently Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one's hands to control a mobile device. Johansen said a replaceable filter (滤光器) would be a cheap, convenient way for most consumers.

    And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

    Last April, on a Sunday, we took one of our “nowhere” drives. My husband was quietly driving along a back road. I was occupied in the front passenger seat watching the scenery.

    I noticed out of the corner of my eye that my husband was struggling to look out of my window. This frightened me, since his eyes should be on the road in front of him. I asked him what he was looking at out of the windows, and he quietly replied, “Nothing.”

    After a few minutes, I looked over at my husband and noticed a tear running down his cheek. I asked him what was wrong. This time he told me, “I was just thinking about Pop and a story he had once told me.” It had something to do with Pop, his friend from childhood, and I wanted to know the story, so I asked him to share it with me.

    He said, “When I was 8 years old, Pop and I were out fishing and he told me that the pine trees know when it is Easter.”

    I have no idea what he meant by that, so I pressed him for more information.

    He continued on… “The pine trees start their new growth in the weeks before Easter because spring is drawing near. If you look at the tops of the pine trees, you will see the yellow shoots. As the days get closer to Easter Sunday, the tallest shoot will branch off and form a cross. By the time Easter Sunday comes around, you will see that most of the pine trees will have small yellow crosses on all of the tallest shoots.”

    I turned to look out of the window and I couldn't believe my eyes. It was a week before Easter, and you could see all of the trees with the tall yellow shoots stretching to the sky.

    The tallest ones shone in the sunlight like rows of tiny golden crosses. May you find your Easter season filled with beautiful golden crosses!

    The arm bones of women who lived 7,000 years ago show a surprising level of strength-even higher than today's professional athletes. that's according to a first-ever study comparing prehistoric(史前的) bones to those of living people. The finding suggests a revision of history- the everyday lives of prehistoric women were filled with hard labor, rather than just sitting at home doing lighter tasks while the men struggled and fought for life.

    Before the study, there are no clear records describing how our ancient ancestors lived. It can be easy to forget that bone is a living tissue, one that responds to the difficulties we put our bodies through, "said lead author Alison Macintosh."Physical force and muscle activity both put pressure on the bone. The bone reacts by changing in shape, thickness and other aspects over time.

    Previous studies only compared female bones to contemporary male bones, the researchers said-and that's a problem, because the response of male bones to stress and change is much bigger than that of women. For instance, as humans moved from a hunter-gatherer lifestyle constantly on the move to a more settled agrarian(农耕的) one, changes can be observed in the structure of the shinbone(胫骨)- and these changes were much more evident in men.

    However, a comparison of the bones of prehistoric women to the bones of living female athletes can help us work out a more accurate picture of what those prehistoric women were doing. "By analyzing the bones of living people and comparing them to the ancient bones, we can start to explain the kinds of labor our ancestors were reforming, Macintosh said. What they found was that women's leg strength hasn't changed a great deal, but their arms used to be very powerful. Prehistoric women, the researchers found, had arm strength 11-16 percent stronger than those of modern rowers, and 30 percent stronger than those of non-athletes.

    I'd like to share a little story with you about something that happened when I was four. I remember it clearly. Our loving family dog was nearing the end of his life. My father picked him up and put him in a little bed we had made for him. Our dog, my companion, whom we had cared for, bit my father when he attempted to help him. How could he? Why? I couldn't understand it. I didn't like him anymore.

    I hadn't thought about that story for a long time but something that happened last week brought it back to me. I went to speak with a friend. When I knocked on the door, I met in an instant an angry look and a few harsh(尖刻的)words. When the door was slammed(砰地关上)in my face, I stood there shocked, and in a rush, I was reminded of my dog bit my father 20 years ago or so. What brought that story back was that same feeling of betrayal.

    Both stories taught me something the next day. You see, when I got up in the morning and was told my dog had died, it became clear to me that he must have been in great pain. For him to have bitten a family member, he could not have been himself. Much the same for the other story when I learned that my friend's wife had just left him.

    We are all beings of our environments, our opinions and feelings. And all of those things can cause you to say and do things that can't be understood by those who are not in the same situation with you.

    If you meet someone either behaving out of character or acting in a way that doesn't seem to fit the situation, put out your hand and be patient when you think it is least possible for him to do so. You may turn around a story that has a sad ending simply by your actions.

Dear Sir,

    There is a plan to build a new supermarket on the edge of the Whitefields housing estate(住宅区), on the land where the local library now is. I live at Whitefields, and I would like to express my concern about this plan. It is not that I am completely against the idea of building a supermarket—I just think that as a community we need to weigh up the advantages and disadvantages before committing ourselves.

    It is clear that the library is under-used and in poor condition. It is also clear that there are very few shops near here and a supermarket would be a good thing to have. But the people who want to build the supermarket seem to think that no one wants the library any more, and that it isn't a must because of the Internet and so on. Is this necessarily true, especially for elderly people? What about young people who don't have the Internet at home and need to go to the library to do their homework? Where can they study if they have to share a room with a younger brother or sister?

    On the other hand, there is an argument that a new supermarket would not only bring more choice of shopping and more convenience for local people, but it would also bring some much-needed jobs for younger people in the town—and this is a good point. What we need to do is consider the effect a supermarket will have on our quality of life. Certainly local people, including me, will find shopping a lot easier and more convenient. But there will also be extra traffic. In a few years from now, the roads in and around will be full of cars in the daytime and delivery lorries at night, and not only that—we will have got used to it, too. Are more jobs and more convenience worth such an influence on our daily lives? Perhaps, but this is what we have to ask ourselves.

    I believe that all the people of Whitefields, and the authority, need to discuss this question in an open-minded way—and I hope that by the time a decision is taken, we will have had a full and fair discussion of the issues involved, and that the local authority will have really listened to everyone's view. Is that too much to ask?

Yours faithfully,

Tom Watkins
