There are many advantages of becoming a professional musician. The biggest advantage is being able to do something you love. You will have the chance to travel to many different places and meet a lot of different people. That will open up your eyes.
However, there are also disadvantages of being a professional musician. One of the biggest disadvantages for most musicians is that they don’t always have enough money. Most of the time, you will be looking for jobs. Sometimes you won’t be able to find a good job. Another disadvantage is the place you live in. If you want to be a musician, you usually have to move to an area that has a lot of jobs, such as New York City. The cost of living in these areas is usually very high. The third disadvantage is that you can’t have a stable (不稳定的) family life. Different jobs will take a musician to different places, so most musicians are unable to have a regular (正常的) family.

_______________________________________________________________________________.
小题2:Why can’t most musians have a stable family life?

While Mrs Dodd, from America, was listening to a talk about Mother’ s Day in a church in 1909, she had an idea of having Father’s Day to honor(纪念) her father, William Smart. Mr Smart used to be a soldier. His wife died when she gave birth to her sixth child. Mr Smart had to raise his six children alone. They lived a hard life.

This morning, we had a school trip to the Dashan Collection House, a building of two floors. It is open from 9:00 am to 5:00 pm. We took the school bus and arrived at 9:00. When we entered the collection house, our eyes were caught by a collection of old photos of the town on the walls of the front hall. Those photos told us something about the history of the town. And then in the Art Room, we saw many pictures of the countryside. The colors of the flowers and trees are rich and bright. All at once, I lost myself in the beauty of nature.
Then we went upstairs. On the left, there were over one hundred different clocks. The oldest clock was already more than two hundred years old. To my surprise, the clocks all worked well and they could tell the right time. It was then ten o’clock, and some clocks produced different beautiful sounds. It seemed to be a concert. How amazing!
On the right there was also a stone collection. The stones were from all over the country. They were in different sizes, colors and shapes. Some looked like different kinds of animals. I really liked one stone that looked like a little monkey. It looked very nice.
The collections there were wonderful. So they stayed there until 11:30 in the morning. I had a great time and really liked the school trip.
