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.

    I like visiting museums on weekends. In them I can see lots of interesting things. In London there are lots of museums. Across from my house is the British Museum. Going to the museum is free but I don't like going there. In the museum I can't speak with people. I can't touch(摸) the things and I can't take photos.

    The Science Museum is not near my home and I can't take photos in it. But I like going there, because I can run, touch the things and speak with people in it. In the museum, I can also do some interesting things by myself. It's a good way to learn about science. The Science Museum is open from 10 am to 6 pm every day. If you have time, please visit it. It's my favorite place in the world.

    Halloween is a festival on October 31st.The name of the holiday means —"hallowed" because it comes the day before All Saints Day.

    Before the festival, people paint homes, shops and classrooms in the traditional Halloween colours, orange and black. Some people make costumes at home. Some people buy them in shops. People also make decorations for the festival. These decorations look like witches, black cats, ghosts, skeletons and jack-o-lanterns. Jack-o- lanterns are pumpkins that are cut to look like faces.

    People think that Halloween is the children's New Year's Eve. On that day children dress up in special costumes and masks. They eat too much, and go to bed very late after celebrating. They go from one door to another saying "trick or treat". People give them candies, cookies, fruit or money.

    Adults and older children also celebrate Halloween with parades (游行）, festivals and costumes parties. One kind of the parties welcomed by children is dunking for apples. Apples are put in tubs (木桶）full of water. People try to get the apples using only their mouths; they cannot use their hands.

    The street food stands（摊）are very popular in Korea . They take their name from the two kinds of hot foods they sell : Dukbokgi and Odeng .

    Dukbokgi is a spicy hot food made of rice cakes and some vegetables . These rice cakes are finger-shaped . They are white , and they are about ten centimeters in length（长度）. They are mixed with sliced vegetables in a pan with a spicy red dressing（调料）. Fifteen minutes later , they are ready to eat . Odeng is made of ground fish . It comes in many shapes : some are square（正方形）, others are round , and still others are stick style . You can buy big or small ones . At these food stands , you can also eat Odeng , which has been boiled in a pot . It is served on a long stick so can eat it easily .

    The food sold at these stands is not expensive , compared to what other foods in Korea cost . Each Dukbokgi and Odeng costs about twenty to fifty cents , depending on the owner .

    Each food stand has its own recipes（菜谱）for its food ; for example , some like to add sugar or other special ingredients（材料）in the food . Usually , there is just one owner , but if the food stand is big , there may be two or three owners .

    When I was an elementary school student , I used to stop at street food stands every day after school to eat street food because I like it so much .
