Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic (经济的) reasons—why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?

    In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate (影响) its surroundings too much, it often improves the attractiveness of the area.

    It is true that there are examples of new buildings which have spoilt (破坏) the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative(保守的)and do not like change.

Although we have to respect people's feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move things forward . If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different , even though that might be the more risky choice.

    A Chinese consortium（联盟）led by China Railway Corp will participate in bidding for a high-speed railroad linking Singapore and Malaysia in 2018, marking another step in China's ambitious strategy to export its high-speed railway technologies to Southeast Asia.

    The consortium, consisting of eight companies including CRRC, China Railway Construction Corporation Ltd, China Railway Signal and Communication Co and Export-Import Bank of China, covers the design, construction, telecommunication, financing, operating and maintenance（维护）sectors for the high-speed rail network.

    A joint tender（招标）for the Kuala Lumpur-Singapore high-speed rail project was issued by the Malaysian and Singaporean government-owned utilities（公用事业）—MyHSR Corp and SG HSR，on Dec 20.According to a joint statement released by the two companies, the potential bidder would be responsible for the design, construction, financing, operating and maintenance of rolling stock and railway systems for the double-track line with a designed speed of 350 kilometers per hour.

    The tender is open to all companies, regardless of their location. A tender briefing will be held in Kuala Lumpur on Jan 23, and proposals need to be submitted by June 29. Submissions will be evaluated based on technical merit（优点）, commercial robustness, financial sustainability and price. The preferred bidder will be selected by the end of next year. The governments of both countries signed a bilateral（双边的）agreement late in 2016 to begin the project. According to the agreement, the high-speed rail link is expected to become operational by Dec 31, 2026, and will cut travel time between Kuala Lumpur and Singapore to just 90 minutes.

    “The move indicates that China's State-owned enterprises have stopped cruel competition to hurt each other,” said Du Chunbu, a professor of rail transportation at Beijing Jiaotong University. “Instead, they have started to form a consortium to better compete with companies from Japan, South Korea, Germany and Canada by bringing their specialties into play.”

    On her first morning in America last summer, my daughter went out to explore her new neighborhood alone, without even telling my wife or me. Of course we were worried; we had just moved from Berlin, and she was just 8. But when she came home, we realized we had no reason to panic. Beaming with pride, she told us how she had discovered the little park around the corner, and had made friends with a few local dog owners.

    When this story comes up in conversations with American friends, we usually meet with polite disbelief. Most are horrified by the idea that their children might roam(闲逛) around without adult supervision(监管).

    A study by the University of California has found that American kids spend 90 percent of their free time at home, often in front of the TV or playing video games. Such narrowing of children's world has happened across the developed world. But German parents are generally much more accepting of letting children take some risks.

    “We are depriving(剥夺) them of opportunities to learn how to take control of their own lives,” writes Peter Gray, a research professor at Boston College. He argues that this increases the chance that they will suffer from anxiety, depression, and various other mental disorders, which have gone up dramatically in recent decades(十年).

    I am no psychologist like Professor Gray, but I know I won't be around forever to protect my girls from the challenges life holds in store for them. And by giving kids more control over their lives, they learn to have more confidence in their own abilities.

    A new high tech mirror, designed specifically for cancer patients, will only become reflective when a user smiles into it. The plug-in device, which exactly looks like a tablet, comes equipped with a mirror, a built-in camera, and a smart material triggered(触发)by some software. Facial recognition technology captures the face and instructs the surface of the mirror to change when a smile is detected. It can hang on a wall or sit on a table, much like a conventional mirror. Unlike a regular mirror, however, the price is currently standing at a surprising $2000—$3000.

    After witnessing a close family member struggle through cancer treatments, Turkish industrial designer Berk Ilhan decided to focus his work primarily on products that would cultivate joy and benefit cancer patients directly.

    “She told me in the first days after her diagnosis, it was difficult for her to look in the mirror and acknowledge she had cancer.” he said.“ Our facial expressions affect how we feel. If we flex(绷紧)our facial muscles to smile, our brains think that something good happened and as a result, we feel happiness.”

    After earning his master's degree at the School of Visual Arts in New York, Ilhan spent several weeks visiting cancer hospitals in Turkey, speaking to both patients and doctors. He spent two years designing and developing the mirror. The idea behind it is that smiling, even when forced, can make us feel better, according to research known as the facial feedback hypothesis. Laughter is linked to improved immune system function, and some researchers claim it can even increase our lifespans.

Ilhan is currently producing the mirror in limited quantities at the previously mentioned price. The product, however, will soon be launching a campaign in which Ilhan hopes to raise enough funds to bring the price down to $500.He also intends to donate the mirror to hospitals when it is financially possible to do so.

    Confident, smart and high-tech, they're followers of pop culture and know what social networking is all about. They're tweens, children between the ages of 10 and 12. These young people are no longer little kids but they are not yet teenagers, because tweens are in a state of transition (转变).

    The tween years are hard for children. From a social point of view, tweens are dealing with quite a lot. They have to face changing relationships, middle school and a whole lot of pressure (压力) to succeed and fit in. They may become angry over seemingly small things. A bad test grade, an argument with a friend, a bad day on the ball field, or a request to clean a bedroom might set them off.

    Elizabeth Hartley-Brewer, a parenting expert in London and author of Talking to Tweens, says, "The tween years are when young people begin to realize the wider world and to see themselves as separate from their families."

    Right now, tweens' friends are everything to them. It's universal for the age, but they show it in different ways. For boys, the whole friendship thing is through technology and sports. Girls like to talk.

    Tweens are also a hot market. What do tweens consider cool? Music is at the top of the cool list, followed by going to the movies. "Being smart" comes third, tied with video games, followed by electronics, sports, fashion and protecting the environment, according to a report.

    Undoubtedly, tweens have great spending power in the United States. It was the tween market that made Justin Bieber and Harry Potter household names. Retailers(零售商) know tweens are a hot market for clothes, music and entertainment. Tweens have their own sense of fashion and enjoy their own parts of popular culture.

One sunny afternoon in the park, I witnessed a remarkable scene. An elderly gentleman was standing by the side of a path, looking confused and lost. Just at that moment, a kind- hearted young girl approached him. She asked him gently what was wrong and listened patiently as he struggled to explain.

Without hesitation, the girl took his hand and slowly guided him along the path, chatting with him to ease his anxiety. They walked together until they reached the place the old man was supposed to be. The old man smiled with thankfulness and relief.

After helping the old man, the girl didn't just leave. She spent some more time with him, sharing some interesting stories and making him laugh. The old man's eyes sparkled with joy, and it was clear that this interaction had brightened his day. The girl's kindness seemed to have an effect, as other people in the park also noticed and were inspired by her actions.

I continued to observe as the girl then decided to stay with the old man for a while longer. They sat on a bench together, and the girl began to tell him about her own life, her dreams, and her adventures. The old man listened attentively, nodding and smiling from time to time. It was a beautiful sight to behold, this unlikely pair sharing such a genuine and heartwarming connection.

This encounter made me reflect on the importance of kindness in our society. In a world that can often seem cold and hurried, acts like the girl's are like the tower of light, showing us the way to a more empathetic（同情的）and caring existence. It also made me think about how we all have the potential to make a difference in someone else's life, no matter how small the act may be.

Now, whenever I recall this scene, it warms my heart and reminds me to be more willing to offer a helping hand, to spread kindness wherever I go, and to believe in the goodness that lies within each of us.
