First Lady Michelle Obama is a big fan of volunteering. Volunteering means working for free to help someone else. Mrs. Obama says volunteering is very important. “It should be part of everyone's life,” she says.

    Many teens agree. They say that helping others feels great and makes a difference. These days, more teens volunteer than work for pay. Teens clean up parks, walk dogs at animal shelters, visit the elderly and more.

    Some cities —including Seattle, Chicago, and Washington, D.C. —require high school students to volunteer. Students must volunteer in order to graduate. The student volunteers learn new skills and help their communities.

    Many parents are in favor of the idea —they say volunteering helps teens build job skills. But most teens don't want to be forced to volunteer. They say they are busy. And they say volunteering is only fun if it's a choice.

Read both sides of the debate and decide.

YES

Volunteering can help teens get into college or get a job.

Many cities and towns need help. Volunteers can help keep important programs going.

Not all teens will volunteer if it isn' t required. Schools should require students to do all they can to get ready for adult life.

NO

Most teens are already very busy with classes, homework, jobs and sports. Forcing them to do more isn't fair.

It should be up to each person. Helping out doesn't feel as good if you have to do it.

Finding a volunteer job isn't always easy. Students shouldn't be kept from graduating because of something they can't control.

    On November 24, 1868, Scott Joplin was born in Texas. He became famous as a ragtime (拉格泰姆音乐) composer and piano player. Ragtime music was an early form of jazz. This music has a lively beat and was developed from the music of African Americans.

    Ragtime became popular in the early 1890s, and the music was played on the piano. The piano player usually made up a melody, then changed it a little bit every time he played. Scott Joplin was very good at composing, or making up music and playing the piano. When he was growing up, Joplin's home was filled with music. Still, Joplin's father did not want him to be a musician. When he was about 14 years old, Joplin left home to travel and start a life of his own. He traveled all over the Midwest playing the piano and composing music. Sometimes he played with music groups. Other times he sang by himself in noisy saloons and bars. In 1899, Joplin wrote Maple Leaf Rag, a ragtime song that became a big hit and earned Joplin the title of The King of Ragtime. In all, he wrote more than 500 songs. Joplin's biggest dream was to compose a ragtime opera. Finally, after 10 years, Joplin completed a ragtime opera which he called Treemonisha. This opera was about a young black woman who became a leader of her people. She tried to help her people gain their freedom and their rights.

    1916, Joplin became very sick. He had a disease that made him forget things and become easily afraid of things. In 1917, he was put in the hospital. He finally died there on April 1, 1917. Scott Joplin's music became popular again in the early 1970s when it was used in a movie called The Sting.

    This story starts with my two kids. We were hiking in the Oakland woods when my daughter noticed some plastic litter in a creek. She looked at me and said, "Daddy? That doesn't go there”.

    When she said that, it reminded me of my summer camp. On the morning of that camping day, right before they'd let our anxious parents come through the gates, our camp director would say Quick! Everyone pick up five pieces of litter, "We got one hundred kids each picking up five pieces, and pretty soon, we got a much cleaner camp. So I thought, why not apply that crowdsourced cleanup model to the entire planet? And that was the inspiration for Literati. The goal is to create a litter-free world. Let me show you how it started. I took a picture of a cigarette using Instagram.

    Then I took another photo, and another. And at the end of a few days, I had 50 photos on my hone and I had picked up each piece, and I realized that I was keeping a record of the positive impact I was having on the planet. That's 50 fewer things you might see, or you might step on, or some bird might eat. So I started telling people what I was doing, and they started participating. I realized that Litterati was more than just pretty pictures; we were becoming a community that was collecting data. Each photo tells a story. It tells us who picked up what, a geo-tag tells us where and a time stamp tells us when. Gradually, the community grew.

    Litter —it's blending into the back ground of our lives. But what if we brought it to the fore front? What if we understood exactly what was on our streets, our sidewalks and our school yards?

    How might we use that data to make a difference?

    I prefer Lynne Truss's phraseology: I am a grammar "sticker". And, like Truss—author of Eats, shoots & Leaves – I have a "zero tolerance" approach to grammar mistakes that make people look stupid.

    Now, Truss and I disagree on what it means to have "zero tolerance". She thinks that people who mix up basic grammar "deserve to be struck by lightning, hacked (砍) up on the spot and buried in an unmarked grave", while I just think they deserve to be passed over for a job—even if they are otherwise qualified for the position.

    Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a compulsory grammar test. If job hopefuls can't distinguish between "to" and "too", their applications go into the bin.

    Of course, we write for a living. iFixit.com is the world's largest online repair manual (指南), and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a strong strike against grammar errors.

    But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the Internet. And, for better or worse, people judge you if you can't tell the difference between "their" "there" and "they're".

    Good grammar makes good business sense—and not just when it comes to hiring writers. Writing isn't in the official job description of most people in our office. Still, we give our grammar test to everybody, including our salespeople, our operations staff, and our programmers.

    Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing—like stocking shelves or labeling parts. It is the same with programmers. Applicants who don't think writing is important are likely to think lots of other things also aren't important.

Animals are humans' best friends. Here we will know about some of those interesting friends.
       Gouldian Finch

Native to Australia, the Gouldian finch has special green, yellow, red and black markings. For the males (雄性), the part between the neck and the stomach is bright purple, while for females, this part is pale purple. We all Have to agree that nature has created some really great animals with the smallest of details.

Keel-Billed Toucan

It is the very same crazy bird from the movie Rio, also known to be the "rainbow billed toucan". The bird has a black body and a yellow face. The color of its bill (喙) is a combination of green, yellow, orange and red, and that's how the name rainbow billed toucan came from. It is rarely seen alone. It travels in small groups of about six to twelve individuals.

The Oriental Dwarf Kingfisher

It is a great tiny bird commonly found in South Asia. This bird is the most brightly colored and the smallest kingfisher species. Its special feature is the orange with bluish-purple head, which can be easily recognized. The throat is white with bright orange colored lines at the bottom. It is a pretty and small bird.

Poison (毒) Dart Frog

It is a kind of very beautiful creature. The bright colors of the poison dart frog send a warning to its natural enemies about its poison. Found in South America, with some of the brightest shades of yellow, copper, red, green and blue, this frog is among those very animals that you have to watch out in the Amazon Rainforest.
