Although considered an excellent

　　form of exercise，jumping rope

　　has

　　never gained widespread acceptance because of two fundamental reasons.First，most people recognize jumping rope as an excellent form of cardiovascular (心血管的) exercise，but they also believe that it is simply too difficult.In other words，they don’t think they’ll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical outcome.Second，many view it as somewhat boring and overly repetitive—not as something fun or enjoyable.

　　As a matter of fact，jumping rope can be great fun if you find a proper way to practice it.Instead of doing the usual two－foot bounce over and over again，people good at rope－jumping often change their pattern every 10 or 20 jumps.A single bounce，a double－bounce，a skip，a knee－up，side swings as well as a variety of other easy－to－learn free－style rope－jumping.

　　Now researchers are learning that jumping rope also prepares the brain for learning.It is an exercise allowing both brain hemispheres to perform in parallel to each other.In short，jumping rope can be a life－long activity requiring little equipment，time and space，yet leading to a much healthier life.

　　41．From the first paragraph we learn that________.

　　A．jumping rope has faded from people’s memories
