HOW ARE BALLET DANCERS TRAINED?

Girls who study ballet generally begin by age eight to ten. Boys often start later. Ballet training is hard work. Ballet students must develop strength, balance, and flexibility as well as grace. They must learn a set of movements and gestures. Girls also learn to dance on their toes. They usually begin pointe (tip-of-the-toes) work after three years of training.

All ballet students practice five basic positions of the feet. These five positions form the basis of almost all ballet steps. All of these positions are performed with the legs turned outward at the hip. The feet should be able to form a straight line on the floor.

The turned-out position gives a dancer a more pleasing “line.” Line has to do with the placement of the dancer’s body, in motion and at rest. All parts of the dancer’s body must be placed in the correct position to achieve good line. Training can improve a dancer’s line. Good line gives a dancer the greatest stability and ease of movement. It also makes the dancer’s body seem light in weight.

All dancers take daily classes to keep their bodies flexible and strong. Most classes begin with warm-up exercises at the barre, a railing that dancers hold onto for support. The second part of the class consists of slow exercises that develop balance and fluid (flowing, not jerky) motion. After this, dancers practice quick movements, such as small jumps and leg extensions, and then large steps, turns, and leaps.

Question: Dancers must place all parts of their body in the correct position to attain  good line.

A. True

B. False

C. Not given (No)

Ta có:

A = b(a - c) - c(a - b)

A = ab - cb - ac - cb

A = ab - ac

A = a(b - c)

A = (-20)(-5)

A = 100
