The operation doesn’t cure the disease that caused the blocked artery【C13】______ the first place. According to some studies,【C14】______ around half of the patients who have had the bypass to relieve one artery will have another blocked artery within five years and in some cases even within one year.
There is of course a【C15】______ rate in any major operation, which【C16】______ from physician to physician and hospital to hospital. The threat to the patient is greatly increased if he is【C17】______ generally poor condition, very advanced in age, or suffering from some serious or debilitating illness. It is essential that the operation【C18】______ by a skilled surgeon knowledgeable【C19】______ this particular technique and in a hospital with the best possible【C20】______ for his use.

选项
A、knives
B、facilities
C、scalpels
D、appliances
答案
B
解析
考查词义辨析。knife指“刀”,scalpel指“手术刀”,在这里的意思都过于具体,与上下文不符。facility通常用作复数,表示各种设施、设备等。instrument是为某个用途而使用的工具。appliance意为“用具,器具”,指的是机械装置或是由动力驱动的器具,尤其指家用器具。这里facilities为最佳选项,意思是说:重要的是,心脏搭桥手术要由一位技术熟练的医生来做,他要非常了解这种特殊的技术,而且医院里还要有最好的设备供他使用。
