12.【2020•长沙市】________ your smartphones, and read for at least 30 minutes, every day! You know, reading helps us to deepen our spiritual world.
A. Put away B. To put away C. Putting away
【答案】A
【解析】句意：收起你的智能手机，每天至少阅读30分钟！你知道，阅读帮助我们深化 我们的精神世界。
考查祈使句。put away收起来放好。分析句子结构可知句中缺少主语，结合题干中“and read for at least 30 minutes”可知此处用祈使句，以动词原形开头。故选A。
