I arrived in the UK last weekend to learn English．So far I have already made a few friends and had some traditional English food there．But after having three days of hamburgers，sandwiches and potatoes，I thought none could be more delicious than Chinese food，especially my favorite﹣huo guo．You can't imagine how excited I was when I got to know that there was going to be a free meal of hotpot to welcome the new students．On the way to the canteen ， I seemed to smell huo guo in the air．

    To my surprise，when I went into the room，I didn't see any sign of huo guo．Where was it？

    With many questions in my head，I sat down to have the free meal．After talking with an English girl，I got to know that Chinese huo guo is completely different from hotpot．Chinese huo guo is written in two words﹣hot pot； and hotpot，one word，is a traditional English dish．

    Hotpot is made from mutton and onion．On the top are pieces of potatoes．People put it in the oven all day in a heavy pot on a low heat．It takes very little effort to prepare．You can often see it at parties in the UK because it's easy to prepare for a large number of people and is not expensive．

    Hotpot doesn't taste bad．However，I still miss huo guo﹣hot pot，two words!

    Father's Day has a very short history. It was started because there was a Mother's Day, and just because some Americans thought that if we had a Mother's Day, we should also have a Father's Day. Father's Day has become important in North America. And shopkeepers (店主) found it was a good way to get people to buy presents for their fathers, presents from their shops.

    By the way, very few countries have a Father's Day, though some have Children's Day, or a special day for boys and another for girls. More and more countries are having Mother's Day, so maybe Father's Day will also become popular before too long. Now, what do people in North America do on Father's Day? The newspapers, radios, and TV tell children what they should do—buy a Father's Day present for your father. They even tell a wife to buy a Father's Day present—not for her father but for her husband, even if he is a not yet a father. And they tell grandchildren to buy a Father's Day present for their grandfathers.

    The important thing to remember about Father's Day is that American children can show their love to their fathers in a more open way.

    I am Frank. In our western countries, there are four seasons or 365 days in a year. Usually, we sleep 8 hours every day. So we have 122 days for sleeping. Then our study or work time is only 243 days left. But there are 52 weekends in a year. Each weekend is two days. We lose another 104 days a year for work. It takes up about one hour to have breakfast and supper. This comes to 15 days over a year. Four free hours each evening takes up 61 days. But we can't work all the time, so we need holidays. We have to remember that we get 2 days' holiday at Easter, 3 at Christmas and 1at the New Year. There are also 4 Bank holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours' lunch every day, and half an hour's coffee break. That comes to 30 days a year. This means that we have only a few days left for study or work every year. What about you in China?

    The bamboo flute is widely used in solo(独奏)and ensemble(合奏) performances. The flute is called dizi in Chinese. The first known flute appeared in China about 7,000 years ago. It was made from the wing bone(翼骨)of a crane(鹤).

    The bamboo flute is one of the most important musical instruments in traditional Chinese music. Many flute melodies are touching and smooth, such as Partridges Fly, one of the best-known flute pieces in China.

    Partridges Fly was created in 1926 by Yan Gufan, a folk musician in central Hunan Province. The melody was soon played both in solo and ensemble performances. It paints a picture of plenty of partridges flying across the sky, making people have a deep sense of hoping for freedom and good life. Many flute artists played Partridges Fly. Wei Zhongle was the first artist to play it in flute solo in the United States in 1938. His performance was recorded and preserved (保存).

    There are three versions (改编本) of Partridge's Fly revised by Lu Chunling, Zhao Songting and Cai Jingmin. And Lu's version is the most popular. He made small changes to each recording.

I went to Grand Canyon (大峡谷) National Park in July 2012 for the firsttime and I knew I wanted to work there as a park ranger（管理员）. Park rangers protect the park's animals, plants, land, buildings, andpeople.

Now, as a park ranger forGrand Canyon National Park, I share the science, history and beauty of this parkwith thousands of visitors from around the world.

National parks are like outdoormuseums. Park rangers have all kinds of jobs, depending on where they work and whatthey studied during college. I teach school field trips（实地考察）, work at visitor centers and helppeople stay safe during their visit.

My favorite part of my jobis showing children their first look at the Grand Canyon during school field trips.Children are often amazed at the canyon's size and colors. Sometimes, they thinkit looks like a painting.

Being a park ranger requiresa lot of energy. I walk several miles and talk with hundreds of people each day.Park rangers must enjoy working with people and speaking in front of groups. Nearly5 million people visit Grand Canyon National Park every year.

Park rangers must also beprepared for any situation. Recently, I broke a traffic jam(堵塞). It was caused by a huge elk（麋鹿）standing in the road. Elks can become dangerous when they get scared,so I asked visitors to stop their cars and take pictures from far away. Believeit or not, I also help protect people from monkeys. It is not allowed to feed animalsin national parks. But sometimes, visitors try to feed monkeys.
