　　Section A

　　Directions: In this section, there is a short passage with 5 questions or incomplete statements. Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words. Please write your answers on Answer sheet 2.

　　Questions 47 to 51 are based on the following passage.

　　Every Western doctor is required to take the Hippocratic oath，by which they swear to never harm their patients.Unfortunately，as medical history shows，many doctors did not make good on this promise.Instead，they resorted to quackery(庸醫的醫術)，and made a living out of fooling people who sought medical help.

　　In the past，quack doctors claimed to have“fixed”problems from poor eyesight to cancer and smallpox (天花).They claimed to be able to work medical miracles，relying on public ignorance of medicine for their “success”.In addition，well-meaning doctors often advocated treatments that harmed their patients instead of helping them：procedures such as bloodletting often made worse the suffering they were intended to ease.
