There are many kinds of music in the world, pop music, classical music, folk music and so on. Do you know country music? It's a traditional kind of music from the southern states of America. I like it very much! It will take me away for a while after I am tired. The guitars and songs will take me to mountains and fields.

    Country music usually talks of everyday life and feeling. It's like the spirit of America, easy to understand, slow and simple.

    Country music developed in the Southern United States. It was the folk music of American countryside. Many of songs tell about the lives of farmers. They talk about love, crops or death. The life of the countryside can be hard, so the words in country music are often sad. At first, people played the music only at family parties.

    But it became more popular later. In the 1920s, people played country songs on the radio, and they made them into records.

    When people in the countryside moved to towns and cities to look for work, they took their music with them. Country music continued to change and became popular across America.

    John Denver was one of America's most famous country singers in the 1970s. His song Take Me Home, Country Roads is well-known and people still play it today.

    Chris is not a traditional explorer(探险者)- he usually works in an office for a large organization. Yet his job can sometimes be just as exciting and dangerous as being an explorer. Chris works for MSF, an organization also known as Doctors Without Borders (无国界医生). MSF sends trained doctors all over the world to help people after a war or a disaster. Chris is a doctor from France who has travelled to many places to organize programmes that help people.

    At the moment, there are over 27,000 trained medical staff(工作人员) taking part in MSF projects and tasks. The organization received the Nobel Peace Prize in 1999. All kinds of doctors can join in MSF. They need to be prepared to go almost anywhere in the world and, of course, they should expect difficult conditions. Doctors with experience in tropical(热带的)diseases are especially useful because most of MSF's work is in Africa. When MSF accepts a doctor for a task, he has to go for at least six months.

    But why would a doctor leave a comfortable life and a good salary to join MSF? According to Chris, the experience is a great help in your career(生涯). At the end of each task, you help people in need and have made a real difference to people's lives.

I always tried to do something for the children in some poor villages. On a hot July day, I{#blank#}1{#/blank#} (参加)a group of volunteers and came to a small village in the west of China to  build a library at a primary school.

After a three-hour ride, we{#blank#}2{#/blank#}(到达) the village  at last. The school was poor and we had to choose a{#blank#}3{#/blank#} (明亮的) small room as the library. Our job was to{#blank#}4{#/blank#} (改变……的位置) the books into the room, place them on the{#blank#}5{#/blank#} (架子) and set up small tables and chairs.

Then we worked on and in the end, we {#blank#}9{#/blank#} (创造) a library.

It only took us one day to build the library, but it will make a{#blank#}10{#/blank#} (差别) to the children's lives.

Life is full of unexpected surprises. Paul was 71 years old and came from England. He liked using a 3D printer to make models.

One day, while Paul was searching for something online, he saw a red car on a website. It was his father's favorite car made in the 1950s. He felt so shocked!

The car brought Paul back to the "good old days". When he was a child, his dad always drove him around London. He sat in the back seat of the red car excitedly. When he went abroad to work, this car took him away from home to say goodbye to his father. To his surprise, many years later, the car showed up online!

Paul decided to buy the car. With his son's help, he bought it. It was a really difficult job to repair the car because it was old and broken. But Paul didn't give up. He spent a long time repairing it. After he tried many times, he finally made the car as good as it used to be with the 3D printer. Paul drove it here and there.

Paul said driving the old car reminded him of his father. The car was seen as a connection between his father and him. It was a treasure for him from the past.

A doctor, a lawyer（律师）, a little boy and an old man were out for a Sunday afternoon flight on a small plane. Suddenly, the plane had engine（发动机） trouble. At last, the pilot took a parachute（降落伞） and shouted to the four people that they had better jump, and then he himself jumped out. Unluckily, there were only three parachutes left.

The doctor took one and said, "I'm a doctor. I save lives, so I must live." Then he jumped out. The lawyer then said, "I'm a lawyer, and lawyers are smart people in the world. I must live." He also took a parachute and jumped out.

The old man looked at the little boy and said, "My boy, I live a long and full life. You are still young. Take the last parachute and live in peace." The little boy handed the parachute back to the old man and said, "Don't worry, grandpa. The smart man in the world just jumped out with my schoolbag."
