【解析】

本文讲述了在武汉爆发新冠肺炎疫情期间，许多当地志愿者送医生和护士去医院工作，虽然医务人员每天与患者亲密接触，有极大被感染的风险，但是仍然有许多人参加这个志愿活动。

1.

句意：自从新冠肺炎病毒爆发以来，武汉的大部分人避免出门来减少感染的风险。

固定搭配：avoid doing sth“避免做某事”，动名词作宾语，所以空格处填going。故答案为going。

2.

句意：所有健康的人都知道，如果没有必要的话，不要去城里的医院，这是非常重要的。

空格处修饰名词people，所以要用形容词作定语。根据括号内提示词，health是名词，其对应的形容词是healthy，所以空格处填healthy。故答案为healthy。

3.

句意：然而，许多当地的志愿者开车送医生和护士去工作。

a large number of表示“许多”，后接可数名词复数，所以空格处填名词复数volunteers。故答案为volunteers。

4.

句意：由于这些医生和护士每天都要认真治疗病人，所以他们与病人有着密切的接触。

空格处修饰动词treat，所以要用副词。根据括号内提示词，care是名词，其对应的副词是carefully，所以空格处填carefully。故答案为carefully。

5.

句意：如果事情像这样持续下去，被感染的风险将会变得更高。

if表示“如果”，引导条件状语从句，从句用一般现在时，主句用一般将来时，所以空格处填will become。故答案为will become。
