共用题干Music Used As a Healing Therapy1 Music has long been used to treat patients suffering from different problems.In 400 BC,its healingproperties were documented by the ancient Greeks.More recently,in both world wars in the last century, medical workers used music therapy（疗法）with people suffering from trauma（外伤）.Currently, it is used as a treatment for many diseases,such as cancer,and it has also been used with patients with long-term painand learning disabilities.2 There is growing evidence that music can cause physical changes to the body which can improve our health.In the Welcome Trust study,which took place over three years at the Chelsea and Westminster hospital in London,patients were asked to listen to musical performances.As a result,it was found that stress levels were significantly reduced,recovery times were improved,and fewer drugs were needed.3 These very positive results are partly due to general well-being（良好的健康状况）.It is already accepted that when people feel happy and have a positive approach to life,they are more likely to feel better and recover from disease quickly.Music increases this feeling of joy and adds to the recovery process.4 However,not all these benefits can be attributed to an increase in general well-being.Music has other effects which have not yet been understood. According to Professor Robertson,a scientist and musician, some effects of music are mysterious and are,therefore,being investigated further. It has been suggested that the sounds and rhythms of music help stimulate the brain and send electrical messages to the muscles.5 Science,however,demands facts and hard evidence.Many in the medical profession have not yet recognized the healing benefits of music,since reports have been based mainly on various stories of evi- dence.These new studies could provide proof to doctors that music is a suitable treatment for many condi-tions. One day doctors may even"prescribe"（开处方）music,but that could be a long time in the future.Music can treat patients partly because________.A:recover from disease quicklyB:there is not enough hard evidenceC:use their minds activelyD:it improves general well-beingE:listen to musical performancesF:it brings many other benefits

共用题干Acupuncture一Old Chinese MedicineFor more than 4,000 years people in Asia have used acupuncture to treat illnesses.________ (46)Today acupuncture is also very popular in Europe,America and Australia.Acupuncture can control pain and sickness.It can also be used if you have a headache or back pain.Some doctors use acupuncture along with regular treatments for asthma,high blood pressure or stress.________(47)Some people think that acupuncture can treat depression and even help people to stop smoking. Many patients feel more energy after a treatment,while others may feel more relaxed.People who practice acupuncture must take courses to learn how to do it correctly._________(48)During treatment the patient lies down and needles are stuck into certain points of the body. There are hundreds of possible points and each one has a certain effect on the body._________(49) For example you stick a needle into the hand to treat problems with your stomach.Acupuncture needles are made of metal and about as thick as a human hair. They normally go less than one cm into the skin.When they are in the skin the acupuncturist may twist them or send electricity through them.The patients rest for a short time and then the needles are removed.Acupuncture normally doesn't hurt. There is also a milder form of acupuncture called acupressure where you don't need needles.Doctors use their fingers to press the points of the body.Chinese medicine teaches us that all acupuncture points are located along pathways called meridians.Each of these meridians carries energy,which the Chinese call "qi" to certain points of the body.If this "qi" gets blocked from an area the person will get sick or feel pain.Sticking needles into the correct points can help "qi" flow again and make the person well.Doctors today are not sure how acupuncture really works.They have not found any proof that these pathways of energy really exist.Some think that needles cause the body to produce pain killing substances.________(50)Some also say that acupuncture only works because patients believe in it._________（50）A:In many places,especially outside of Asia,only doctors are allowed to perform acupuncture.B:The earliest written record of acupuncture is found in the Huangdi Neijing.C:Doctors have even used acupuncture to stop pain during an operation.D:The points can also be very far away from the place of pain.E:Others think that the needles block pain signals that travel along the nerves to the brain.F: It is an old Chinese form of healing in which your skin is pierced with thin needles to relieve pain.
