Questions 1to 5 are based on the following passage:

Some psychologists (心理学家)maintain that mental acts suchas thinking are not performed in the brain alone, but that one’s muscles alsoparticipate. (76)It may be said that we think with our muscles in somewhatthe same way that we listen to music with our bodies.

You surely are not surprised to be told thatyou usually listen to music not only with your ears but with your whole body.Few people can listen to music without moving their body or, more spe-cifically, some part of their body. Oftenwhen one listens to a symphonic concert on the radio, he is attracted to directthe orchestra （乐队）even though he knows there isa good conductor on the job.

Strange as this behavior. may be, there is avery good reason for it. One cannot derive all pos-sible enjoyment from musicunless he participates, so to speak, in its performance. The listener “feels”himself into the music with more or less noticeable motions of his body.

(77) The muscles of the body actuallyparticipate in the mental process of thinking in the same way，but this participation is lessobvious because it is less noticeable.

1. Somepsychologists think that thinking is ____________.

A.not a mental process

B.more of a physical process than a mental action

C.a process that involves our entire bodies
