Mr Li: Sam, did you enjoy your first Spring Festival in China?

Sam: Yes, I did. During this festival, many family members get together.

Mr Li: Yes. I hear that at Thanksgiving Americans also get together for a special meal. It sounds similar.

Sam: Yes. It's similar. During these holidays, both the Chinese and Americans come home and have a big dinner. It's great fun.

Mr Li: What do you think are the main differences between the Spring Festival and Thanksgiving?

Sam: Well, we take part in different activities and eat different kinds of food. In China, people usually set off fireworks and eat dumplings. In the US, we usually watch a Thanksgiving parade and an American football game on TV. We also eat turkey.

Mr Li: That's interesting.

    The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit, look again. It may not be a cloud, but a Flogo -- a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products, logos, and events.

These funny logos are made with soap bubbles（肥皂泡） mixed with a little helium gas（氦气） ,which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $ 2,500 a day, can make a Flogo every 15-25 seconds.

    Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 20, 000 feet, they usually float around at 300- 500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.

    Flogos are Green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.

    In a map of the world you can easily find two big cities, London and New York. London is the biggest city in Europe. New York is the biggest city in America. The streets in London are crowded and there is one of the world's biggest underground railway systems(地铁系统) .The streets in New York are just as crowded as those in London. And the New York subway carries more people each day than the London underground. There are a lot of big stores in these two cities. But New York has more supermarkets than London.

    In London there are many palaces(宫殿) and churches, for example, St. Paul's. New York isn't as old as London, and it hasn't got many old buildings. But its skyscrapers(摩天大楼) are much bigger than the buildings in London.

    London has more parks than New York, But New York's Central Park is much bigger than the biggest park in London.
