I've loved my mother's desk since I was just tall enough to see above the top of it when Mother sat doing letters. Looking at the ink bottle, pens and white paper, I decided that the act of writing must be the most wonderful thing in the world.

    Years later, during her final illness, Mother kept different things for my sister and brother, “But the desk,” she said again, “is for Elizabeth.”

    I never saw her get angry, and never saw her cry. I knew she loved me, and she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter. They never happened and a gulf opened between us. I was “ too emotional (易动感情的) ”, but she lived “on the surface”.

    As years went by, I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know that she did forgive (原谅) me.

    I posted the letter and waited for her answer, but it didn't come. I wondered if the letter had even got to her. I only knew that I had written it, and I could stop trying to make her into someone she was not.

    Now the present of her desk told me that she was pleased that writing was my chosen work, though she had never been able to. I cleaned the desk carefully and found some papers inside … a photo of my father and a one-paper letter, folded (折叠) and refolded many times.

    Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.

    Were dinosaurs (恐龙) warm-blooded or cold-blooded? According to a new study, scientists have found that they were somewhere in the middle. This new study shows that dinosaurs were very different from most of today's animals that are either warm or cold-blooded.

    “I think we were all surprised by this,” said Felisa Smith from the University of New Mexico. “The idea certainly took some getting used to.”

    A study by a team of scientists led by John M. Grady of the university studied many different kinds of dinosaurs in their research. They looked at growth rate (比率), body temperature and body size of different kinds of dinosaurs.

    How are warm-blooded animals different from cold-blooded animals? Warm-blooded animals like humans can control their body temperature. They eat a lot, and burn calories (卡路里) quickly. They have a more active lifestyle than cold-blooded animals. While cold-blooded animals such as snakes do not control their body temperature. Instead, they must use sunlight to keep warm, and they move much more slowly. Cold-blooded animals do not need to eat very much. Their bodies slow down in colder temperatures.

    Besides dinosaurs, there are other animals that are not completely warm-blooded or cold-blooded, such as great white sharks.

    With the start of the new term, the students around the country exchange their fun and fashionable clothes for boring school uniforms. But not all schools are fashion deserts. Colorful sports shoes, school bags, T-shirts and even drink containers are breathing life into campuses.

    "The uniform makes us look like a bunch of clones, especially when we are doing morning exercises on the playground," said Qing Pei, a Senior 2 from Shanghai Qibao High School. "But the boys wear different sports shoes and girls have different decorations in their hair. These are the areas where you can express yourself," said Qing.

    Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.

    "Nike and Adidas basketball shoes, although they are still the must-have items for many of my friends, are becoming out-of-date," Qing added. He explained that "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."

    "Still in fashion are the various baseball caps and American-style T-shirts with random (随意的) English words printed on them," said Qing. "The accuracy of the written message is not important. Often, the words are misspelt. Sometimes they do not even make sense, "Qing said with a smile.

    Besides sports shoes and T-shirts, styles and colors of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls.

    Other fashionable items are the colorful drink containers which are now popular among girls this term.

    "Some teachers are surprised to see a teenager sucking a bottle like this at school and criticize it as a childish regression (退化). But some girls just love it," said Yang Rui, a Senior 3. from High School attached to Xi'an Jiaotong University.

    Saber Miresmailli was on vacation in London when, caught in a bit of traffic on London Bridge, he decided to take a photo of Tower Bridge.

    “I noticed the couple,” he said. “At that moment, I did not see anyone from the wedding party or a photographer with the couple, so I took several pictures. Usually, my pictures are not very good given the fact that I don't use flash and I don't stop to compose (构图)-so when we get back after two weeks, I was very surprised to find this one turned out so well.”

    Miresmailli said, “I thought to myself, if it was me getting married, I would have wanted the picture.” So he posted the photo on Facebook and attached a few friends with the hope of finding the couple and passing them the picture. What happened next, he said, “was crazy”. “I received more than 2,000 requests from perfect strangers and lots of positive and negative emails.” Until this afternoon, almost 230,000 people had shared his Facebook post on the photo.

There's also been an uncertain identification of the couple. It's likely that their names are Laura and James. “If it's the right couple,” Miresmailli said, “they are on their honeymoon in Bali and have no idea about the photo. I believe they will be shocked to find out about their fame.”

    Miresmailli said he's been drowned by the interest in the photo. “I just want to give them their picture and go back to work and tend my tomatoes,” he said.

    Everglades National Park (大沼泽地国家公园) is located in the state of Florida. It is the largest wilderness in the entire country and makes up 25% of the wetlands in the state. The park is home to several rare and endangered species. It is also the third largest national park in the US, after Death Valley and Yellowstone. Each year, about 1 million tourists visit the park. On a global level, it has been announced as a World Heritage Site.

    Unlike most other national parks, Everglades National Park was created to protect an ecosystem (生态系统) from damage. In 1947, President Harry Truman spoke at the official opening of Everglades National Park, saying the goal of creating the park was to protect forever a wild area that could never be replaced.

    10,000 different islands make up Everglades National Park. Each of these islands is lived by natural wildlife. The Everglades is home to about 15 species that are endangered. In addition, more than 350 bird species and 300 species of fresh and saltwater fish live within the park. The Everglades is also home to 40 species of mammals and 50 reptile species.

    There are many ways to explore the Everglades. Visitors can see alligators (短吻鳄) while hiking the Anhinga Trail. The Everglades is one of the only places on Earth where freshwater alligators and saltwater crocodiles live in the same area. Visitors using airboats are likely to see large groups of birds. Some visitors might enjoy riding bicycles through Shark Valley. Others may want to move slowly through waters where they can see insects and wildlife closely.

    According to experts, changes to the Everglades are becoming a danger to several different kinds of wildlife. They say it is a result of actions the US government began more than 50 years ago, and settlers began even earlier.
