In most parts of the world, many students help their schools make less pollution. They join environment clubs (环境俱乐部). In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No garbage (垃圾) 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 only the students but also the teachers！Cars give pollution to our air, so remember:

    Walk, jump, bike or run.

    Use your legs! It's lots of fun.

    Turn off the taps! Do you know that some toilets can waste twenty to forty cubic (立方的) meters of water an hour？In a year, that would fill a small river！In environment clubs, students mend those broken toilets.

    We should love our environment. Let's work together to make it better.

    Mrs. Cooper lives in a house close to Manchester Airport in London. She often uses her iPad to track the planes that fly overhead and explore(探索) the world with Google Earth.

    "I'm crazy about the planes, so I choose the Flight Tracker to see where the planes around me are going. It's a wonderful way to keep in touch with the world," she said. "I use it nearly all the hours of daylight, 2-3 hours in the morning, then again in the afternoon."

    Mrs. Cooper taught painting when she left school. She had a laptop（手提电脑）, but struggled（费力）with it. " Her problem was that she couldn't see the cursor（光标）, and her hands shake so hard that she almost can't use the mouse." said her 63-year-old daughter, Jean. "I was in America visiting my daughter, and I played with an iPad and decided to buy one for my mother."

    Jean got some apps for the iPad, so her mother could learn how to use them. "She uses it several hours a day, and is curious(好奇的) to keep up with everything new. She reads the news, sends emails and uses Face Time to make video calls to us all. We're glad that she can enjoy her life with the magic thing." she said.
