Living is risky. Crossing the road, driving a car, flying, swallowing an
aspirin tablet or eating a chicken sandwich--they can all be fatal. Clearly
some risks worth taking, especially when the rewards are high: a man 【S1】______
surrounded by flames and smoke generally considers that jumping out of a
second floor window is an acceptable risk to save its life. But in medicine a 【S2】______
few procedures, drugs, operations or tests are really a matter of life and death. 【S3】______
There may be sound medicine reasons for accepting electrical shock treatment, 【S4】______
but such reasons are totally dependent in the balance of risks and benefits for 【S5】______
the patients. Surgery for cancer may cure or prolong a life, but the removal of
tonsils (遍桃体) cannot save anything a sore throat. Blood pressure drugs 【S6】______
definitely help some people live after a heart attack, but these same drags may
be both necessary and harmful for those with only mild blood pressure 【S7】______
problems. Deciding how much discomfort and risk we are preparing to put up 【S8】______
with in the name of better health is a high personal matter, not a decision we 【S9】______
should remain to doctors alone. 【S10】______ [br] 【S7】
选项
答案
necessary→unnecessary
解析
语篇逻辑错误 此处but提示与上文形成转折关系。上文说“确实能够帮助一些人继续生存”,那么下文转折后的意思就应该是否定的。另外necessary与下文的harmful用and连接是矛盾的,所以要用表示否定意义的unnecessary。
