Let's read the conversations and guess the meaning of the following expressions.

    Beijing Opera is my favourite. Bao Zheng always has a black face and Guan Yu has a red face in Beijing Opera. But many people don't know why.

    I come from America and I have lived in China for six years. I like Beijing Opera very much. I think Beijing Opera is very interesting. I can learn a lot about Chinese history. Now let me tell you the art of Beijing Opera facial(脸部的) paintings(画).

    In Beijing Opera facial paintings, different colours and patterns（图案） are for different roles. For example, a black face for fair (公正的) people. A red face is for brave(勇敢的) people. A white face is for bad people. Blue and green faces are for heroes(英雄). The gold face is for gods.

    Do you have a special talent or skill but there is no one that enjoys it? If so, you might want to go to Christ church, New Zealand, for the World Buskers Festival.

    January is summer time in New Zealand, and the entertainment (娱乐活动 ) takes place outside. However, this is not the typical outdoor music concert or festival you have known. The buskers-people who perform on the streets and in other public places—bring the city to life with amazing entertainment.

    The event begins in late January and attracts (吸引) around 300,000 visitors every year with about 500 performances. The performances include the circus(马戏表演) and magic acts, street dancing and singing, and other crazy forms of entertainment.

    One of the best things about the festival is how well it attracts many people, from the youngest to the oldest .Laughs are everywhere, especially when unprepared visitors are asked to become a pan of the performance.

    The festival director says, "We have performers from all over the world. Most of the performances are free, so it means you can bring your family and spend a whole day here."

    There's something for everyone at the World Buskers Festival, one of the biggest and most popular street festivals in the world.

    Dogs are good friends of humans. Some dog lovers want to take their pets along with them wherever they go. However, many malls, bars and restaurants don't allow dogs inside. But in good news for dog owners, the world's first bus tour for dogs appeared on the streets of London last month.

    The tour is free. It takes owners and their dogs to some of London's best parks and hottest dog-walking spots(地点). For example, the buses stop at Hyde Park and Green Park. The tour guides on the buses explain the history of dogs in London and about the many corgis(柯基犬) owned by Queen Elizabeth II. They also give the owners a map of dog-friendly bars and restaurants in the city.

    American people like to say "Thank you" when others help them or say something kind to them. People in many countries do so, too. It is a very good habit.

    You should say "Thank you" when someone passes you the salt on the table,  when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is very beautiful. "Thank you" is used not only between friends, but also between parents and children, brothers and sisters.

    "Excuse me" is another short sentence they use. When you hear someone say so behind you, you know that someone wants to walk past you without touching you. It's not polite to break others when they are talking. If you want to speak to one of them, say "Excuse me" first, and then begin talking. You should also do so when you begin to cough or make any noise before others.

    Let's learn to say "Thank you" and "Excuse me".
