问题     If you’re in charge of Christmas dinner, with all its interconnected tasks and challenges of timing—when to preheat the oven, whether to put the potatoes in before the eggs—why not write down every【S1】______that needs doing, in order, then do them, checking them off as you go? That can be very helpful.
    The Checklist Manifesto, written by the journalist and doctor Atul Gawande, shows the importance of checklist when hospital doctors are【S2】______to tick off items on checklists as they carry out routine but critical procedures. In one trial, the rate of infections from intravenous(静脉内的)drips fell from 11% of all patients to zero 【S3】______because staff were compelled to work through a checklist of no-brainer items, such as【S4】______their hands. A more recent study, which included UK hospitals, suggested that wider use of checklists might【S5】______40% of deaths during treatment.
    Unlike in medicine, the【S6】______uses of checklists in everyday life—a list for holiday packing, for instance, aren’t usually matters of life and death. The idea of making a checklist is so stupidly obvious that it seems impossible it could have so【S7】______an effect. But the truth is that all life, not just medicine, is【S8】______complex; if highly trained intensive-care specialists can forget a【S9】______step, it’s sure that anyone might.
    Besides, the step-by-step structure of checklists can narrow your【S10】______to the next action. All you have to remember is to "do the next right thing". Then the next, and the next.
A)potential B)required C)crucial D)subject
E)vast F)action(!)washing H)prevent
I)simply J)increasingly K)focus L)normally
M)gradual N)request O)shaking
【S9】
选项
答案C
解析 此处需填入形容词。该词修饰step，形容词词库中crucial可以修饰它，表示“关键步骤”。如此．也凸显出列清单的重要性，符合语境。此处意思与第2段中的critical相近，故选crucial。
