No one doubts that students should study languages, maths and science in high school, but some may object to the idea that they should study art and music as well. To them, these subjects are useless for students’ future and are not worth the time and effort. In my opinion, however, it is necessary for middle school students to study art and music.

Art and music are a precious culture legacy(遗产), which bring us pleasure and enjoyment. Have you ever been deeply moved by Beethoven’s famous Fifth Symphony(第五交响曲)? Have you ever been fascinated by the colorful starry night produced by Vincent Van Gogh in his paint? Have you ever longed for the moving love between the Butterfly Lovers when you hear this well-known Chinese melody(曲调)? Art and music are not only images and sounds, but something beyond them. They are the products of passion and human wisdom(智慧).

Art and music help make students more creative. Artists and musicians are considered the most creative people in the world. It is because art and music sharpen their senses and provide a different perspective (视角) for them to see the world. Many great scientists benefited from art and music. Einstein, the greatest physicist in the 20th century, as well as an excellent violin player, is a good example.

Enjoying art and music is also a good way to relax. Middle school students, who typically carry heavy burdens of study, will definitely(明确地)benefit from it.

To sum up, art and music should absolutely be included in the middle school courses, for they can bring students pleasure and relaxation.
