We've talked about snails（蜗牛）and their slow move.But much of the time snails don't move at all.They're in their shells（壳）—sleeping.

    Hot sun will dry out a snail's body.So at the least sign of hot sun,a snail draws its body into its shell and closes the opening with a thin cover.Then it goes to sleep.A snail will die in a heavy rain.So whenever it rains,it goes inside its shell house and goes to sleep.A snail can sleep for as long as it needs to.It can take a short sleep.Or it can sleep for days at a time.And it spends all the winter months in its shell,asleep.

    the shell.When hungry,the snail looks for food.It can't see very well.Its eyes,at the ends of the top feelers（触角）are very weak.But its sense of smell is very strong.It helps the snail to the new greens.Then the snail's little mouth goes to work.

    A snail's mouth is no longer than the point of a pin（针）.Yet it has 256,000 teeth!The teeth are so small that you can't see them.But they do their work.If you put a snail in a hard paper box,it will eat its way out.And if a snail wears out its teeth,it will grow new ones.

    Mostly,a snail looks for food at night.But on cloudy days it eats in the day time.It cats all day long.A snail can go on eating for hours and never feel full.

    International Children's Day is coming up on June 1st. Here we have chosen some films from around the world that are most worthy for children to see.

    Kes (1969)

    Director: Ken Loach

    Country: United Kingdom

    Storyline: Bullied (欺凌) at school and getting little attention at home by his mother and older brother, Billy Casper, a 15-year-old boy from a working-class family, finds peace in his pet falcon (猎隼), Kes.

    Modern festival-goers who worry about ending up with a dead mobile phone battery after days stuck in a muddy field with no electric plug power points may now have a solution—power boots.

    Mobile phone company European Telco Orange has introduced a phone charging prototype(原型)— a set of thermoelectric gumboots or Wellington boots with a “power generating sole” that changes heat from the wearer's feet into electrical power to charge battery-powered hand-helds.

    The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole（鞋底）of the Wellington boot there's a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you'll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers(薄片). When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.

    But the prototype boot does have one shortcoming. You have to walk for 12 hours in the boots to make one hour's worth of charge.

    When I was small, my mother and I would walk to our local library in Franklin Square. As we didn't always have access to a reliable car, walking hand in hand was the most convenient way to get anywhere. It was at story time for children that both my mother and I made lasting friendships.

    Today, I am fortunate to live around the corner from the Cold Coast Public Library in Glen Head and a short walk to the Sea Cliff Children's Library. My 18-imonth-old son, Colin, and I find ourselves in Sea Cliff several times a week, meeting and making friends. Well, that is what many people don't understand-a library is more than books; it's a community.

    Sure, the library in Franklin Square was the place where I was introduced to Judy Blume novels. But it was also the place where I got my first email address in 1997. At the library, friends and I learned how to research colleges and search for scholarships on the Internet. The library was the place where we sometimes giggled(咯咯笑)too loudly, and where the librarians knew us by name. Their knowing our names wasn't a bad thing. When I came home from my first term at Binghamton University, Mary LaRosa, the librarian at the Franklin Square library, offered me my first teaching job.

    I now teach reading at Nassau Community College. My students are often amazed that they can check out books via their smartphones and virtually(虚拟地)visit a variety of Long Island libraries. The app used by Nassau and Suffolk county public libraries, as well as the college library, makes their homework easier by helping them find resources. Even though they can't always easily visit their local libraries, the library is always with them.
