[单项选择]The Body Thieves
In the early nineteenth century in Britain, many improvements were being made in the world of medicine. Doctors and surgeons were becoming more knowledgeable about the human body. Illnesses that had been fatal a few years before were now curable. However, surgeons had one problem. They needed dead bodies to cut up, or dissect (解剖). This was the only way that they could learn about the flesh and bones inside the body, and the only way to teach new surgeons to carry out operations.
The job of finding these dead bodies was carried out by an unpleasant group of people called "body snatchers". They went into graveyards (墓地) at night and, using wooden shovels to make less noise, dug up any recently buried bodies. Then they took the bodies to the medical schools and sold them. A body could be sold for between ￡5 and ￡10, which was a lot of money at that time. The doctors who paid the body snatchers had an agreement with them—they never asked any questions. Th

B. they had been strangled.
