    We've talked about snails (蜗牛) and their slow move. But much of the time snails don't move at all. They are 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 his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
    In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
    A snail's mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can't see them. 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.

    Steve Jobs, co-founder and former CEO of US technology giant Apple, has died at the age of 56. Mr Jobs had announced he was suffering from cancer in 2004. Apple said he had been "the source of countless innovations（创新）that enrich and improve all of our lives" and had made the world "immeasurably（无法衡量的）better".
    Tributes(赞美之辞) have been made by technology company bosses and world leaders, with US President Barack Obama saying the world had "lost a visionary（有远见卓识的人）". "Steve was among the greatest of American innovators —— brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it," said Mr Obama.
    A statement from Mr Jobs's family said they were with him when he died peacefully on Wednesday. "In his public life, Steve was known as a visionary; in his private life, he loved his family deeply," they said, requesting privacy and thanking those who had "shared their wishes and prayers" during his final year.
    Apple said the company had "lost a visionary and creative genius(天才) and the world have lost an amazing human being". Tim Cook, who was made Apple's CEO after Mr Jobs stood down in August, said his predecessor had left behind "a company that only he could have built, and his spirit will forever be the foundation of Apple". Flags are being flown at half mast outside the Apple headquarters（总部） in Cupertino, California, while fans of the company have left tributes outside Apple shops around the world.
    The heads of other leading technology companies have also paid tribute, including Microsoft boss Bill Gates, who said "For those of us lucky enough to get to work with him, it's been a great honour. I will miss Steve very much."
    Facebook founder Mark Zuckerberg thanks Mr Jobs for "showing that what you build can change the world" while Sony Corp president and CEO Howard Stringer said: "The digital age has lost its leading light." South Korea's Samsung, which is involved in a case with Apple over patents(专利), admired Mr Jobs for his "Completely new and different changes to the IT industry".

    If you think texting(发短信) while walking is dangerous, just wait until everyone starts wearing Google's smart, Internet-connected glasses. These glasses can do anything you now need a smartphone or tablet computer(平板电脑) to do —and then some.
    In Google's video, a guy wearing the "Project Glass" is shown getting subway information, making an appointment with a friend for coffee and showing the directions in a bookstore, all with the help of the glass. It ends with him playing an instrument for a woman and showing her the sunset through a video chat.
    The "Project Glass" Google displayed have a sleek(光滑的) wrap-around look and appear nothing like 3-D glasses. In development for a few years, the project is the idea of Google X, the online search-leader's secret department that produced the self-driving car and could one day send elevators into space.
    Google posted the video and short blog post about “Project Glass” on April 4^th, asking people to offer feedback(反馈) through its Google Plus social network. By April 5^th, about 500 people did, voicing a mix of amazement and concern about the new technology. What if people used it in cars and could not concentrate on driving? What about the effect on(对……有影响) your sight of having a screen so close to your eye?
    Some asked for the glass, but Google isn't giving those out just yet. The company didn't say when normal people can expect to get their hands on a piece of Project Glass, but going by how quickly Google will come out with new products, it may not be long. Enderle said that it could be about six months to a year before wide tests are coming, and a year or more for the first version(版本) of the product.

    When you watch TV and play video games you make global(全球的) warming worse! It may seem hard to believe, but when electricity is made, so are greenhouse gases(温室气体). This means that every time you use electricity you help make global warming worse!
    Cars are also making global warming worse. They burn fossil fuels(化石燃料) in their engines, and send lots of greenhouse gases into the air.
Global warming may be a big problem, but we can all help stop it. People can try to drive their cars less. Or even get ones that run on sunlight! You can also help. Let's try one of these top ideas:
    (1) Try to use less electricity. Turn off lights, your television, and your computer when you've stopped using them. To make electricity, fossil fuels are burned in big factories. But burning fossil fuels also makes greenhouse gases. You should also try to watch less TV.
    (2) Plant trees. Not only is it a fun thing to do, but it is also a great way to lower the number of greenhouse gases in the air. Trees take carbon dioxide out of the air when they grow.
    (3) Don't throw away your rubbish, try to recycle it. If rubbish is not recycled, it is put in the ground. There it rots(腐烂) and makes a greenhouse gas called methane(甲烷).So try to recycle cans, bottles, plastic bags and newspapers. It'll make you feel great! And it'll help the Earth.

When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.

Large Internet companies (公司）such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems(系统）. These systems send the heat into the air.

A company in Holland(荷兰） thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.

Boaz Leupe, head of the company, says the e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.

Five homeowners in Holland are testing the heating system in their homes.

"We pay for the computer using, so, in that way, homeowners get heating for free," Boaz says.

Jan Visser is one of the homeowners. "If you use the computer more, the e-Radiator produces more heat," he says. "It can't provide enough heat if you don't use your computer often." But he is ready to try it. It's a great help for his family.

The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.

How do you deal with plastic bags from the supermarket? Throw them away or recycle them? How about eating them?

The bags are not harmful to the environment, Humans and animals can safely eat them. Indian company EnviGreen has made a bag with natural materials. It looks and feels just like plastic, but can break down(分解) easily.

Ashwath Hedge who set up the EnviGreen Company spent four years doing experiments(实验) with 12 natural materials. They include potato, corn, vegetable oil and banana. He made the materials into liquid(液体) and used the liquid to make the bag.

Although the EnviGreen bag is more expensive than a common plastic bag, it has many advantages. According to the Wall Street Journal, it takes 1,000 years for common plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in less than a minute in boiling water. Hedge was happy to show it in his interview, he put an EnviGreen bag in water and ate it with a smile.

There are more than 15,000 tons of plastic waste in India every day. But only 9, 000 tons are processed. In China, 3 billion plastic bags are used every day. Maybe the EnviGreen bag could be a solution(解决方法) to the world problem of plastic pollution.
