If you want a more interesting experience when you arrive in a new city or country, here are some better ways to travel, both for you and for the environment.

    Way 1 Get out of the car and walk. It's slower but it's the greenest way to travel. It's also the most rewarding（有益的）way to see a city, but remember to wear comfortable shoes.

    Way 2 Cycling is also  a good choice. Many hotels now  offer free bikes to guests. It is convenient for people to travel around the city. Some also provide electric bikes that make it easier to go up hills and on longer journeys. Some cities also have mobikes, and you can pick up one easily. It's not free but very cheap.

    Way 3 If you have to take transport in a city, try to take public transport. Most cities now offer lots of information and very clear maps at the city's website.

    Way 4 If possible, take buses, trains or ships to travel from city to city. They are usually greener than cars and planes.

    Way 5 When the only way to travel is by car, rent(租) an electric car. Many car rental companies now offer them, so always ask!

    “Dreams may be more important than sleep. We all need to dream” some scientists say. Dreams take up about one quarter of our sleeping time. People have several dreams each night.

    Dreams are like short films. They are usually in color. Some dreams are like old films. They come up over and over again. That may be the dreamer worrying about something. Dreaming may be a way of trying to find an answer.

    Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.

    Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is still at work when we dream. That is why we may have a long sleep and still tired after waking up.

    Our school is a green school．What makes it green？

    First，we have a lot of trees．There are trees in front of and behind every building．Some trees are green only in spring and summer．And some are green all year round．The trees make our school look like a big forest.

    And our school is a green one because we "go green". How do we go green？We have two green days every month．On green days，no students or teachers go to school by car．And we have clean﹣up Day every month．That day，students go to streets to pick up rubbish．Also，we have tree﹣planting Day every spring．We plant young trees on hills．We have three green clubs The members of the clubs look after those trees well．

    Green is not only a colour．It is about life．Please go green with us and make the world a more beautiful place．

    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.
