9 阅读理解。 John Hunter had three advantages.He had a brother who was a doctor and he thus able to learn about diseases and their effects.His natural curiosity led him to observe and study the lives of wild animals in the countryside and he had strong and skillful hands,so essential to a surgeon.In fact he became in a short time so famous that he was asked to lecture,but John preferred the practical work of the surgeon. Soon after becoming a surgeon Hunter joined the army.He learnt a great deal from his experience of dealing with soldiers" wounds.In particular,he studied how to prevent a wounded man from bleeding too much,learning thereby how the nerve system functioned in the bodies of animals and humans.But there were many things he did not know about and which could only be learnt by dissection.And this posed a problem. The Christian church whose authority was complete on many matters opposed on dissection. Cutting up dead animals to find out about their organs,and how these functioned was thought a disgusting thing to do,and to cut up a human body,even though dead,was thought to be evil. Surgeons had to pay grave diggers to steal bodies for dissection.Hunter once paid $7000 for the body of an eight-foot Irishman whose skeleton can still be seen in the Royal College of surgeon"s museum.To be a surgeon was thought so inferior an occupation that many operations were carried out by barbers. But Hunter continued with his experiments,at the time learning more about how our bodies worked,and he found new ways of operating on people so as to save both their limbs and their lives.If a man was brought to him with a bad tumor (肿瘤)on his leg,Hunter did not,as most surgeons would have done,cut off his leg,but tried first to remove the tumor and treat the leg so that the leg might be saved. 1._________ we think is the most important of John Hunter"s three advantages. A.His brother"s occupation B.A natural curiosity C.Lived in the country D.Strong and skillful hands .Fr2om the passage we guess that a barber was _________. A.looked down upon at that time B.looked up to at that time C.regarded as equal to other occupations D.not permitted to carry out operations 3.The word " dissection" from the context most nearly means ___________. A.cutting something up into different parts under study B.putting different parts of something together to cure the patient C.operating on somebody without medical instruments D.stealing dead bodies from graves to cut into pieces 4.From the last paragraph we can conclude that __________. A.Hunter continued with his experiments B.Hunter was learning more about how out bodies worked C.Hunter found new ways of operations D.Hunter was very conscientious and responsible
