Want to say "hello" from Disneyland? Send a post card!
   Beautiful scenes of paradise (乐园), wild animals, silly pictures — you can find them all in one place. Where? On a post card! Have people always sent post cards? No. Before post cards, people liked sealed letters.
   The idea for the first decorated (装饰) post card came to John P. Charlton in 1861. He thought a simple card with decorations would be a great way to send a note. Then in the late 1800s, post cards with pictures appeared. By law, people had to write their note on the front ——on the picture! The back was only for the address. Several years later, England allowed a divided-back post card. Then people could write their note on the back left side and put the address on the right. During the early 1900s, the golden age of post cards, picture post cards became a craze of the world. In 1908, Americans alone mailed over 677 million post cards. Today, post cards are the third most popular collection in the world after stamps and coins.

    What do you think of black cats? Are they unluckier than cats of other colors? Many people in Western countries think so. Scientists at the University of California, Berkeley (UC Berkeley), did a study on cat colours and people's understandings of cat personalities.

    The study found that people do judge(判断) cat personalities by color. Scientists did a survey(调查) on the Internet. There were 49 statements (描述) matching five cat colorings with 10 personalities. People think orange and bi-colored (双色的) cats are friendly, tri-colored (三色的) cats are not generous, and white cats are calm, lazy and shy. As for black cats, people think they don't have special personalities.

    But why do so many people dislike keeping black cats as pets? People think black cats have less special personalities, which might be because of their bad reputation (口碑). They think black cats may bring bad luck, especially at Halloween. Movies and television shows also make people believe that.

    Although people have these ideas, UC Berkeley scientists give another reason: people don't think black cats are pretty enough. After all, nothing can show black cats are unluckier than other cats. “You can't judge a cat by its color, because it's the personality of the cat, not the color, that will let you know if the cat is right for you,” Cathy Marden, a scientist said.

    Vienna (维也纳) is a beautiful old city on the river Danube. It's the centre of European (欧洲的) classical music. From 1750 a lot of composers and musicians came to study and work in Vienna. The most famous family of musicians was the Strauss family.

    There were two composers called Johann Strauss: a father and a son. The father, Johann Strauss the elder, wrote and played music for a classical dance—a waltz(华尔兹). His waltzes made him famous all over Europe.

    The son, Johann Strauss the younger, was even more successful and popular than his father. His most famous waltz was The Blue Danube. He wrote it in 1867. Strauss and Mozart were two of the most important composers.

    Mozart was born in Austria in 1756. Before he was six he played not only the piano, but also the violin. He wrote his first opera (歌剧) at the age of 12 and hundreds of beautiful pieces of classical music. But he died in 1791 when he was only 35. Some people say he was the greatest European composer.
