阅读短文，回答题。Hypnosis (催眠)
1 Increasing numbers of American doctors are using a technique known as hypnosis. They say hypnosis often can help persons suffering pain and stress. It also can help speed the healing of burns, and treats some forms of asthma and some skin diseases. Hypnosis is not new. It has been used for many years both in scientific research and to please crowds at public gatherings.
2 Hypnosis is commonly described as a condition similar to sleep. But, experts say it is more a form of sleep, in which the thought becomes so intense that it is no longer just a thought. To the person, it becomes reality.
3 Hypnotized patients are reported to have increased self-control and a reduced sense of pain. Some doctors use hypnosis to limit pain during a medical operation. Hypnosis is used mainly when the patient may have problems with usual anesthetic or pain-killing drugs. Doctors may advise hypnosis for women who are giving birth. Dentists may use it in place of traditional pain-killing drugs, such as novocaine. Hypnosis also has been used to treat burn victims. Researchers have found that burn victims who are hypnotized improve faster than those who are not. But, they are not sure why this happens.
4 Hypnosis can reduce or end a patient's pain. But experts say this does, not mean the patient is cured. The problem that caused the pain still must be treated.
5 Experts also say persons cannot be forced to do something they would normally op-pose. That is why hypnosis often is not effective in treating cigarette smokers and persons who eat or drink too much. The success of the technique depends on how much someone wants it to succeed.
