Are you interested in students in other countries? Do they also have so much homework like you? What do they do in their spare time?

    On April 8, a report came out on the lives of high school students in China, Japan, South Korea and the US. It surveyed around 6200 students from the four countries last year. You will find the answers to many of your questions in this report.

    Who study hardest?

Chinese students spend the most time studying. Nearly half of Chinese students (48.65%) spend more than two hours on their homework every day. That's much more than students of the US (26.4%), Japan (8.2%) and South Korea (5.2%).

    Who sleep most often in class?

Japanese students fall asleep in class most often. About 45% of them said they sometimes sleep in class. In South Korea, it's 32%; in the US,21%; and 5% in China.

    Who are the most distracted?

    American students are the most active in class, but also the most distracted. 64.2% said they chat with friends in class; 46.9% said they eat snacks in class; and 38.9% said they send emails or read storybooks in class.

    What do they do after school?

    In their spare time, most Chinese students study or surf the Internet. Most American students go out to play with their friends. Most Japanese students do physical exercise. Most Korean students watch TV.

    World of Stamps

    Video images bring stamps to life and attract visitors who explore the surrounding displays. Visitors encounter the world's first postage stamp — the 1840 Penny Black and learn how it revolutionized communication. Stamp images, including Dr. Martin Luther King's "I have a dream" speech and the stamp that helped raise almost $72 million dollars for breast cancer research, explain how stamps have shaped history and honored people and places worldwide.

Gems of American Philately

    Visitors have the opportunity of examining 13 of the most rare and highly valued stamps in the world of the stamp collection, including the most famous American stamp of all, the 1918 Inverted Jenny. A video explains why the Inverted Jenny and other stamps displayed here are the most valuable. The treasures in this area are rarely available for public viewing. Each tells a story about an important event in US history.

    Mail Marks History

    The markings on mail provide valuable clues to the surprising ways mail has been transported over time, including challenges and even disasters encountered along the way. You will understand these markings by following the journeys of three historic letters.

    Connect with US Stamps

    Visitors explore their own connections with stamps. At three touch screen tables, they create their own stamp collection based on the topics that interest them most. They can also create their own stamp designs. Visitors have the chance to view videos in which stamp designers talk about their craft, stamp collectors explain what they collect and why, and footage(片段) shows the process of making stamps.

    A mystery surrounds my grandmother's collection of salt cellars (盐瓶). No one in the family seems to know when she started collecting them, or exactly how many she had.

    My grandmother died just over two years ago. At 91, she had spent 30 years without her right leg, which was removed due to cancer the year I was born. She was a poet, an artist, a food lover and a salt cellar collector. The funny thing about the salts, as she called them — I never once heard her say salt cellar — was that although everybody knew they were her hobby and everyone was always searching for them at yard sales or in stores, nobody seemed to know what they meant to her and they just wanted to make her happy. Grandma kept her salts in a dark wooden corner display case in the living room. Since her death the case has remained exactly as she left it. Grandpa tries his best to preserve his memories of her just as they are.

    Now I am collecting, too. Collecting memories about my grandmother's hobby, a way she spent her time. And as I hold one of them in my hand, I picture her holding it in her hand on the day she got it. She is smiling. My mother and her two sisters all have small collections, but my mother admits that she was more interested in finding salts to send to Grandma.

    Grandma once wrote a poem titled “When April Comes”. The poem contains the line, “When April comes and I am not around, remember me when daffodils are found.” Now, Grandpa is working on a poem with the line, “April came and you were not around”.

    But she was, somehow. She was there in the memories left behind by her possessions.

    Climate change is perhaps the key issue of our time. Often, however, it is presented to us as being so abstract that it seems impossibly distant. For those of you looking for something a little more concrete, a new report suggests that the effects of climate change may significantly affect coffee.

    The report, put out by The Climate Institute, describes the effects of climate change on various coffee-growing nations and the resultant effects on the plants and those who grow them.

    Coffee Arabica plants, which produce 70% of all commercial coffee, can be adversely affected by even a half-degree change in typical weather conditions. This sensitivity to temperature puts the plant at increased risk of the effects of climate change.

    In Central America the average temperature has risen by a full degree Celsius since 1960. In Ethiopia the average temperature has increased by 1. 3 degrees. This increase is enough to have notable effects on the plants. In Tanzania the productivity per hectare of coffee has fallen by half since the 1960s due to changes in temperature.

    Indeed, studies claim that by 2050 the area of the world suitable for growing coffee will be cut by half. Coffee production is likely to then be pushed to higher elevations (海拔) to take advantage of lower temperatures, but this will not be enough to make up for lost lowland areas.

    Coffee is the second most traded goods by developing nations, and the inability of producer nations to export it could cause dramatic chain reactions in their economies. Millions of people make a living in the production, processing, transport, and sale of coffee; their livelihoods would stand to take a blow as growing areas decrease and prices rise.

    As the temperature keeps rising, your cup of coffee will become much more expensive, and it may also carry an aftertaste bitterer than usual, for all those workers in the coffee belt left without the means to make a living as conditions worsen. Not only that, but the economic effects will cost the West millions in increased foreign aid.

Surviving Hurricane Sandy (飓风桑迪)

    Natalie Doan, 14, has always felt lucky to live in Rockaway, New York. Living just a few blocks from the beach, Natalie can see the ocean and hear the wave from her house. "It's the ocean that makes Rockaway so special," she says.

    On October 29, 2012, that ocean turned fierce. That night, Hurricane Sandy attacked the East Coast, and Rockaway was hit especially hard. Fortunately, Natalie's family escaped to Brooklyn shortly before the city's bridge closed.

    When they returned to Rockaway the next day, they found their neighborhood in ruins. Many of Natalie's friends had lost their homes and were living far away. All around her, people were suffering, especially the elderly. Natalie's school was so damaged that she had to temporarily attend a school in Brooklyn.

    In the following few days, the men and women helping Rockaway recover inspired Natalie. Volunteers came with carloads of donated clothing and toys. Neighbors devoted their spare time to helping others rebuild. Teenagers climbed dozens of flights of stairs to deliver water and food to elderly people trapped in powerless high-rise buildings.

    "My mom tells me that I can't control what happens to me," Natalie says. "but I can always choose how I deal with it."

    Natalie's choice was to help.

    She created a website page matching survivors in need with donors who wanted to help. Natalie posted introduction about a boy named Patrick, who lost his baseball card collecting when his house burned down. Within days, Patrick's collection was replaced.

    In the coming months, her website page helped lots of kids: Christopher, who received a new basketball; Charlie, who got a new keyboard. Natalie also worked with other organizations to bring much-need supplies to Rockaway. Her efforts made her a famous person. Last April, she was invited to the White House and honored as a Hurricane Sandy Champion of Change.

    Today, the scars (创痕) of destruction are still seen in Rockaway, but hope is in the air. The streets are clear, and many homes have been rebuilt. "I can't imagine living anywhere but Rockaway," Natalie declares. "My neighborhood will be back, even stronger than before."
