问题     Dr Richard Bergland, a brain researcher at the Harvard Medical School, has written a paper suggesting that human brain is basically a gland. Building on this view, Dr. Carmine Clemente, director of the Brain Research Institute at UCLA, has been looking into the secretions of the brain. He has estimated that there may be thousands of such secretions—all of which play a part in the functioning of the body.
    What to me is most fascinating of all about these secretions is that they are not locked away or completely removed from the conscious intelligence. It is true that the mind has no ongoing awareness of the numberless functions generated by the brain—the beating of the heart, the actions of the nerve cells, and the functions of all the glands. But the fact that we have no direct knowledge of these functions as they occur does not mean that they are barred from supervision over them. The significance of biofeedback—a term used to describe the ability of the mind to enter into the working of the body—is that human being may actually be able to exert increasing control over themselves and may be able play an important role in overcoming illnesses.
    Numerous medical reports now cite instances in which individuals have been able to direct their bodies in ways generally believed to be beyond the reach of the conscious intelligence. At the UCLA School of Medicine, I witnessed a demonstration which a man controlled his own heartbeat. He could speed it up or slow it almost to a stop merely by concentrating. Such a performance is not unknown in Eastern cultures, but it was startling, to say the least, to see such a demonstration in an American medical school, with a dozen or more physicians as fascinated observers of this use of biffed back. Patients are using biofeedback techniques at the Menninger Foundation in Topeka, Kansas and at other medical centers as a means of relieving their migraine(周期性偏头痛)headaches or lowering their blood pressure. The evidence is incontrovertible that medical changes take place in the body as a result of mental functions or moods.
Which of the following is the fact about biofeedback?

选项 A、Biofeedback is now being applied to the cure of diseases.
B、Cases show that the human mind can supervise some body functions.
C、Human beings are capable of strengthening their own mental control.
D、The adoption of biofeedback at the Menninger Foundation is questioned.

答案C

解析 第二段最后一句讲到生物反馈的意义在于人们可以增加对自己的控制。因此选C。A项“生物反馈已被用于治疗疾病”,文中只是说生物反馈或许对治疗疾病有很大的作用,但是这种方法还没被利用。B项“实例说明人脑可以管理身体机能”,这句话是对的,但不是生物反馈的有关内容。D项文中没有提及。
