　　Analyzing the physics of dance can addfundamentally to a dancer's skill. Although dancersseldom see themselves totally in physical terms-asbody mass moving through space under theinfluence of well-known forces and obeying physicallaws-neither can they afford to ignore the physics ofmovement.For example, no matter how much adancer wishes to leap off the floor and then startturning, the law of conservation of angular momentum absolutely prevents such amovement.

　　Some movements involving primarily vertical or horizontal motions of the body as a whole, inwhich rotations can be ignored, can be studied using simple equations of linear motion in threedimensions. However, rotational motions require more complex approaches that involveanalyses of the way the body's mass is distributed, the axes of rotation involved in differenttypes of movement, and the sources of the forces that produce the rotational movement.

　　The primary purpose of the passage is to

　　A.initiate a debate over two approaches to analyzing a field of study

　　B.describe how one field of knowledge can be applied to another field

　　C.point out the contradictions between two distinct theories

　　D.define and elaborate on an accepted scientific principle

　　E.discuss the application of a new theory within a new setting

　　The author mentions all of the following as contributing to an understanding of thephysics of dance EXCEPT

　　A.the law of conservation of angular momentum

　　B.analyses of the way in which the body’s mass is distributed

　　C.equations of linear motion in three dimensions

　　D.analyses of the sources that produce rotational motions

　　E.the technical terms for movements such as leaps and turns

　　The author implies that dancers can become more skilled by doing which of thefollowing?

　　A.Ignoring rotational movements

　　B.Understanding the forces that permit various movements

　　C.Solving simple linear equations

　　D.Learning the technical terms utilized by choreographers

　　E.Circumventing the law of conservation of angular momentum

　　Analysis of which of the following would require the kind of complex approachdescribed in lines 14-19?

　　A.A long leap across space

　　B.A short jump upward with a return to the same place

　　C.A sustained and controlled turn in place

　　D.Short, rapid steps forward and then backward without turning

　　E.Quick sidesteps in a diagonal line

　　正确答案:B E B C
