问题 The Chinese have used a method called acupuncture(针灸)to perform, operations for about 4,000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them.
To learn how to use the needles takes about one month of training. But to be skillful requires greater time. The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.
Today, the Chinese doctors are trying to learn more about acupuncture. They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, would prevent the pain in the area of the mouth.
A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep, It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation but the chemical may make the patient sick for a few hours or a day. [br] It can be learned from the passage that______.

选项 A、the person performing the acupuncture knows a lot about the making of needles
B、an operation now needs fewer needles than in the past
C、acupuncture has existed in China for as long as 2,000 years
D、few patients prefer acupuncture to chemicals

答案 B

解析推理判断题。可用排除法。由第二段可知，针灸师应知道的是怎样下针和在哪下针，而不是怎样制针，所以A不对。根据第一段，针灸已在中国流传了大约4，000年，而不是2．000年，所以C不对。由最后一段可知，超过一半的患者在麻醉时喜欢针灸胜于化学药物，所以D也不对。由第二段最后一句可知B是对的。
