John Blanchard stood up from the bench, straightened his Army uniform, and studied the crowd of people making their way through Grand Central Station. He looked for the girl whose heart he knew, but whose face he didn't, the girl with the rose.

    His interest in her had begun thirteen months before in a Florida library. Taking a book off the shelf he found himself intrigued, not with the words of the book, but with the notes penciled in the margin. The soft handwriting reflected a thoughtful soul and insightful mind. In the front of the book, he discovered the previous owner's name, Miss Hollis Maynell. With time and effort he located her address. She lived in New York City. He wrote her a letter introducing himself and inviting her to correspond. The next day he was shipped overseas for service in World War II.

    During the next year and one month the two grew to know each other through the mail. Each letter was a seed falling on a fertile heart. A romance was budding. Blanchard requested a photograph, but she refused. She felt that if he really cared, it wouldn't matter what she looked like.

    When the day finally came for him to return from Europe, they scheduled their first meeting -- 7:00 PM at the Grand Central Station in New York. “You'll recognize me,” she wrote, “by the red rose I'll be wearing on my lapel.” So at 7:00 he was in the station looking for a girl whose heart he loved, but whose face he'd never seen.

    I'll let Mr. Blanchard tell you what happened: A young woman was coming toward me, her figure long and slim. Her blonde hair lay back in curls from her delicate ears; her eyes were blue as flowers. Her lips and chin had a gentle firmness, and in her pale green suit she was like springtime come alive. I started toward her, entirely forgetting to notice that she was not wearing a rose. As I moved, a small, attractive smile curved her lips. “Going my way, sailor?” she murmured.

    Almost uncontrollably I made one step closer to her, and then I saw Hollis Maynell. She was standing almost directly behind the girl. A woman well past 40, she had graying hair tucked under a worn hat. She was more than plump, her thick-ankled feet thrust into low-heeled shoes. The girl in the green suit was walking quickly away. I felt as though I was split in two, so keen was my desire to follow her, and yet so deep was my longing for the woman whose spirit had truly companioned me and upheld my own.

    And there she stood. Her pale, plump face was gentle and sensible, her gray eyes had a warm and kindly twinkle. I did not hesitate. My fingers gripped the small worn blue leather copy of the book that was to identify me to her.

    This would not be love, but it would be something precious, something perhaps even better than love, a friendship for which I had been and must ever be grateful. I squared my shoulders and saluted and held out the book to the woman, even though while I spoke I felt choked by the bitterness of my disappointment. “I'm Lieutenant（中尉）John Blanchard, and you must be Miss Maynell. I am so glad you could meet me; may I take you to dinner?”

    The woman's face broadened into a tolerant smile. “I don't know what this is about, son,” she answered, “but the young lady in the green suit who just went by, she begged me to wear this rose on my coat. And she said if you were to ask me out to dinner, I should go and tell you that she is waiting for you in the big restaurant across the street. She said it was some kind of test!”

    It's not difficult to understand and admire Miss Maynell's wisdom. The true nature of a heart is seen in its response to the unattractive. “Tell me whom you love,” Houssaye wrote, “And I will tell you who you are.”

    We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment – and our wallets – as these outdated devices consume much more energy than the newer ones that do the same things.

    To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life – from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and box-set TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and e-readers showed up in 2007.

    As we accumulated more devices, however, we didn't throw out our old ones."The Living-room television is replaced and gets planted in the kid's room, and suddenly one day, you have a TV in every room of the house," said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices-we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TV's with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions(排放) more than doubling during the 1992 to 2007 window.

    So what's the solution(解决方案)?The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more on-demand entertainment viewing on tables instead of TVs and desktop computers could cut energy consumption by 44%.

    September is an exciting month in every college freshman's life. For many, it's the first time that they've left home to live in a new environment. But after the hustle and bustle（喧嚣）of a few weeks, excitement gives way to a less enjoyable emotion— homesickness.

    Homesickness manifests（显露）itself in many ways. You may miss mum's cooking, your pets, or even your old bed. All this becomes a fond memory of the past. Homesickness can be a bitter feeling for many students, especially when faced with the challenges of settling into an unfamiliar environment.

    But remember, you're not alone. According to a recent BBC article, 70 percent of British college students experience homesickness. In this increasingly globalized world in which people migrate to faraway places for a relationship, education or work, homesickness is a feeling shared by many adults.

    Homesickness can have similar symptoms to depression and in extreme cases it can develop into a panic attack. As for the term, homesickness or nostalgia wasn't invented until the 17th century. It was considered a disorder by a Swiss physician, who attributed soldiers' mental and physical discomfort to their longing to return home, “nostos” from Greek, and the accompanying pain, “algos”.

    Studies in recent years, however, have shown that nostalgia may have some benefits to our mental health. After a decade of surveys and researches, Constantine Sedikides, a US social psychologist, found that nostalgia is what makes us human. He explains that nostalgia can resist loneliness, boredom and anxiety. Therefore, it's necessary for college students to learn some ways to overcome the uncomfortable feeling.

    An earthquake is one of the most common natural disasters. It may cause great damage.  So it is wise to learn some simple safety tips to protect yourself or your family members.

    Fragile items, like those made of glass should usually be placed on a lower surface, near the ground instead of placing them on cupboards higher up. Never place them near your bed, sofas and other furniture where you would be sitting or lying down. When there is a strong movement, these pieces will fall on the floor directly and not on you.

    There is a strong chance of short circuits（短路）and fire breakouts during an earthquake. Make sure you turn off electrical connections and gas immediately when an earthquake happens.

    During an earthquake, lie beneath an object that is not easily damaged. Do not go near objects that could directly fall on you. Never use the elevator to go down. Stay inside until the shaking stops and it is safe to go outside. Research has shown that most injuries happen when people inside buildings try to go out. Use the staircases at all times.

    If you are outdoors, do not take shelter under a tree, streetlights, electric poles or tall buildings. If you are driving, stop your car and stay in a safe place. Do not park your car under a tree or any tall object.

    If trapped in debris (瓦砾堆), cover your mouth with a handkerchief or clothing. Tap on a pipe or wall so rescuers can find you. Use a whistle (哨子) if one is available. Never shout for help. Shouting can cause you to breathe in dangerous amounts of dust. Do not light a match because you may burn yourself. Do not move about or kick up dust.

    Do you have a spare room in your house? What about a driveway for your car? Both of these can help you make money. Many people who are feeling the pinch are taking advantage of what's been called the “sharing economy”.

Perhaps the best-known example of a company in this field is Airbnb—an American web business which allows you to rent out your spare room to holidaymakers. It says it operates in 34,000 cities and it has over 1,500,000 listings.It seems to have concerned the market!

A British company is doing something with parking spaces. JustPark's founder, Anthony Eskinazi, says,“When I had the original idea, Ispotted a driveway close to a sports stadium. It would have been so convenient if I could have just parked in that driveway rather than in commercial car park.” And he has a big clientele（客户）:around 20,000 people have advertised their spaces on the site, and he says around half a million drivers use it. There are other sites doing very similar things, like Uber and Lyft—these let drivers share their cars with other passengers. Any driver knows how valuable a place to park is .A church near Kings Cross in central London has apparently made over £200,000 by renting out space in its yard to travelers!

    Because this is a new business world, those rules aren't there yet and many people are happy to share...as long as it pays!

    But the sharing economy has its critics: the competitors of these new companies. People who run things like traditional B&B, commercial car parks and taxi services are afraid of ending up out of pocket. And there is another issue: regulations on these new business are unclear. How will renting out your driveway affect your neighbor?

    Tiny microbes(微生物)are at the heart of a new agricultural technique to manage harmful greenhouse gas. Scientists have discovered how microbes can be used to turn carbon dioxide into soil-enriching limestone(石灰石), with the help of a type of tree that grows in tropical areas, such as West Africa.

    Researchers have found that when the Iroko tree is grown in dry, acidic soil and treated with a combination of natural fungi(霉菌)and other bacteria, not only does the tree grow well, it also produces the mineral limestone in the soil around its root.

    The Iroko tree makes a mineral by combining Ca from the earth with CO2 from the atmosphere. The bacteria then create the conditions under which this mineral turns into limestone. The discovery offers a new way to lock carbon into the soil, keeping it out of the atmosphere. In addition to storing carbon in the trees, leaves and in the form of limestone, the mineral in the soil makes it more suitable for agriculture.

    The discovery could lead to reforestation(重新造林)projects in tropical countries, and help reduce carbon dioxide in the atmosphere in the developing world. It has already been used in West Africa and is being tested in Bolivia, Haiti and India.

    The findings were made in a three-year project involving researchers from the Universities of Edinburgh, Granada, Lausanne and Delft University of Technology. The project examined several microbiological methods of locking CO2 as limestone, and the Iroko-bacteria way showed best results. Work was funded by the European Commission under the Future Emerging Technologies (FET) scheme.

    Dr Bryne Ngwenya of the University of Edinburgh's School of GeoSciences, who led the research, said: "By taking advantage of this natural limestone-producing process, we have a low-tech, safe, readily employed and easily operating way to lock carbon out of the atmosphere, while improving farming conditions in tropical countries?
