Answer 1

【答案】C

【解析】

句意：——你知道我们要怎样摘下口罩吗？——我们应该清洁双手，小心摘下口罩，安全处理口罩，再次洗手。

考查宾语从句。when we can take off a mask我们什么时候可以摘下口罩，表时间；why we can take off a mask我们为什么可以摘下口罩，表原因；how we can take off a mask我们怎样摘下口罩，表方式；根据上文“We should clean our hands, remove the mask carefully,dispose of the mask safely and wash our hands again.”讲述如何摘下口罩的流程，故选C。
