In most parts of the world, many students help their schools make less pollution. They join “environment clubs”. In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No-garbage lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classes that make the least garbage and report them to the whole school.

    No-car day. On a no-car day, nobody comes to school in a car. Not the students and not the teachers! Cars give pollution to our air, so remember: walk, jump, bike and run. Use your legs! It's lots of fun.

    Turn off the water! Did you know that some toilets can waste twenty to forty cubic (立方) meters of water an hour? In a year, it would fill a small river! In environment clubs, students mend those broken toilets. We love our environment. Let's work together to make it clean.

    Laughter Yoga(瑜伽) is one form of yoga. Madan Kataria, a doctor in Mumbai, India invented it. He believed that people had forgotten how to really laugh. Through his research he made an interesting discovery. The human mind does not know the difference between forced laughter and real laughter. Forced laughter can also lead to a feeling of happiness.

    And then Kataria had the idea for a group of people who would laugh together. He gathered a few of his friends together. They met in a public park in Mumbai. That small group grew and grew! And this is how people began to do Laughter Yoga. People doing Laughter Yoga usually meet together in a Laughter Club. Kataria's friends formed the first Laughter Club in 1995.

    Today, there're over 5,000 Laughter Clubs in 53 countries. But what exactly do people do in a Laughter Club? People in Laughter Yoga meetings usually do a series of exercises. The exercises include body movement, correct breathing, and of course, laughter! At the beginning of the meeting, people may have to force themselves to laugh. But by the end, everyone is usually laughing in a real way! Each meeting is a little different. But there are common exercises groups may do.

    Experts say that the exercises help blood move around the body faster. They also say that Laughter Yoga helps people deal with the bad things in their lives. They say that a person may go into a Laughter Club meeting feeling sad, angry, or worried. But then, people act happy. After a time, forced laughter becomes real laughter. This is one reason why people may enjoy laughter Yoga so much

    October 15^th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donators (捐赠者) will give 150,000 bars of soap to schools in Ethiopia.

    Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after washing the toilet, after cleaning a baby and before touching food.

    Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children's Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germs(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub(揉搓) it into all areas, including under the fingernails. Rub for at least twenty seconds. Then rinse well under running water. At last, dry your hands with a clean cloth or wave them in the air.

    The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗) or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(感染) themselves by touching their eyes, noses or mouths. Then they can infect others.

    When I was 5 years old, I started losing weight. My parents noticed I was pale and always thirsty. They had me tested to see if my blood sugar was high because they thought that might be causing my symptoms.

    My blood sugar was five times higher than normal. That can be deadly. My parents rushed me to the hospital. That's when my whole life changed.

    The doctors said I had Type 1 Diabetes (糖尿病).That means my body can't make insulin (胰岛素).There's no cure.

    My parents had to give me insulin shots every day and I had to get over my fear of needles quickly. Sometimes I had 10 band-aids on my fingers at once.

    Now that I'm older, I check my own blood sugar and give myself shots. About four years ago, my mom started traveling to rural Guatemala. She goes twice a year to help people in need.

    I have been a Girl Scout since kindergarten. For a Girl Scout project, I put together a team to go to Guatemala to test people there for diabetes. We went for four days last July. We tested 378 children and 100 adults. We found three adults with a different kind of diabetes, called type 2. We also found one little girl with dangerously low blood sugar. She cried when we told her. She had been feeling dizzy and didn't know why. It was like replaying what happened to me when I was little. I talked through a translator, but everyone understood hugs. I gave more hugs than I've ever given.

    Having type 1 diabetes is hard. But I have accepted it readily. It has helped me meet amazing people. It has made me responsible and independent. It has also shown me the power of taking action. I'm going back to Guatemala this summer to test more kids. I want to help as many kids as I can. But my greatest wish is for a cure. Type 1 diabetes changes your life. If no other child ever has to have it, that would be amazing.

    William Butler Yeats, a most famous Irish writer, was born in Dublin on June 13, 1865. His childhood lacked the harmony that was typical of a happy family. Later, Yeats shocked his family by saying that he remembered "little of childhood but its pain". In fact, he inherited (继承) excellent taste in art from his family—both his father and his brother were painters. But he finally settled on literature, particularly drama and poetry.

    Yeats had strong faith in coming of new artistic movements. He set himself the fresh task in founding an Irish national theatre in the late 1890s. His early theatrical experiments, however, were not received favorably at the beginning. He didn't lose heart, and finally enjoyed success in his poetical drama.

    Compared with his dramatic works, Yeats's poems attract much admiring notice. The subject matter includes love, nature, history, time and aging. Though Yeats generally relied on very traditional forms, he brought modern sensibility to them. As his literary life progressed, his poetry grew finer and richer, which led him to worldwide recognition.

    He had not enjoyed a major public life since winning the Nobel Price in 1923. Yet, he continued writing almost to the end of his life. Had Yeats stopped writing at age 40, he would who probably now be valued as a minor poet, for there is no other example in literary history of a poet Auden wrote, among others, the following liners:

    Earth, receive an honored guest:

    William Yeats is laid to rest.

    Let the Irish vessel (船) lie

    Emptied of its poetry.

A video of dolphins playing in the wake of the waves near a man-made island, east of the Hong Kong-Zhuhai-Macao Bridge, has caught the attention from netizens across China.

The 55-km Hong Kong-Zhuhai-Macao Bridge is the world's longest cross-sea bridge, connecting the mainland province of Guangdong with the country's two special administrative regions, Hong Kong and Macao.

During the nine-year bridge construction period, researchers have identified and registered a total of 2,367 dolphins, with no injuries of any dolphins reported.

According to local authorities, the Pearl River Estuary Chinese White Dolphin Reserve has supported more than 100 researchers in studying and protecting the mammal and trained thousands of dolphin watchers. Luo Guocai, a certificated dolphin watcher, said his duty was to conduct a 10-minute observation of the sea each time before construction started. The dolphins have to breathe every few minutes above the water, and in order to prevent potential harm, the watchers would knock on their boat a few times to scare them away.

The preservation efforts never stopped even after the construction was completed. "Managerial personnel will continue to monitor the nearby environment and the dolphins via intelligent equipment including the bridge video surveillance(监控) system, the underwater tunnel's environmental monitoring as well as specially established research and observation stations on the man-made islands," said Yu Lie, deputy director of the bridge management bureau.

"Currently, Hong Kong, Macao, the country's two special administrative regions, and Guangdong plan to establish a conservation alliance for the dolphins, involving non-governmental organisations in the routine rescue, information sharing, and scientific research," said Chen Hailiang, head of the administration of the reserve. "We are constructing a bigger rescue and conservation base as well as increasing tissue samples and gene banks in a bid to better preserve the dolphins for generations to come," Chen said.
