【解析】
试题分析：本文介绍家庭安全系统，及保证孩子安全在家的一些要点。
【1】F 空前的意思是：对于早期的家庭安全，系统的基本设计是不让坏孩子进来。空后的意思：但是确保没有大人在场时，他知道如何安全的做。所以这里选F（现在很多父母也用它们来保证单独在家的孩子安全。）与上下文一致。故选F。
【2】E 空前的意思是：每个孩子都应该记住他/她的全名和地址，以及父母的家中，工作地及个人手机号码。空后的意思：如果你的孩子太小了，记不住这些信息，那么他/她可能太小了，任何时间都不适合单独在家。所以这里选E（把这些信息粘贴到家里电话旁。）与上下文一致。故选E。
【3】D 空后的意思：如果门或者窗户开了一点，孩子有理由猜测有不该在的人在屋里。所以这里选D（教你的孩子回到家时观察事物。）与上下文一致。故选D。
【4】A 空后句意：另外，设定一个规则，独自一人在家时，决不能在外面玩耍。所以这里A（告诉单独在家的孩子决不要回应门铃或者电话。）符合语境。故A正确。
【5】G 空前句意：当你的孩子回到家或者离开家，以及解除或者安装系统时，你都可以收到提示信息。因此这里G（如果你的孩子忘记了重装系统，你可以打电话告诉他。）与上下文一致。故选G。
