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 【M1】______
when the rewards are high: a man 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 【M2】______
few procedures, drugs, operations or tests are really a matter of 【M3】______
life and death. There may be sound medicine reasons for accepting 【M4】______
electrical shock treatment, but such reasons are totally dependent
in the balance of risks and benefits for the patients. 【M5】______
Surgery for cancer may cure or prolong a life, but the removal
of tonsils (扁桃体) cannot save anything a sore throat. 【M6】______
Blood pressure drugs definitely help some people live after a
heart attack, but these same drugs may be both necessary and 【M7】______
harmful for those with only mild blood pressure problems.
Deciding how much discomfort and risk we are preparing to 【M8】______
put up with in the name of better health is a high personal matter 【M9】______
not a decision we should remain to doctors alone. 【M10】______
【M7】
选项
答案
necessary改成 unnecessary
解析
用词不当。本句属于篇章理解错误,necessary and harmful 构成一对矛盾,因而要把表示正面含义的 necessary 变成表示负面含义的 unnecessary。译文:人们心脏病发作时,血压药肯定能救治病人,但是同样的药物对只有轻微心脏病的病人来说,就可能是没有必要或者有害。
