16. 文中先介绍了家庭规则，下方的规则涉及教室、课后使用电脑等校园相关内容，由此可知该部分是学校规则，故选C。
17. 根据家庭规则中的“Get up at 6:00 a.m and go to bed by 10:00 p.m.”，从晚上10点到早上6点的睡眠时间为8小时，因此孩子至少能睡8小时，故选B。
18. 前文提到“Turn on the computers”（打开电脑），结合“after class”（课后）的语境，可判断“turn off”的意思是“关闭”，故选D。
19. A选项：原文是“作业完成前不能见朋友”，并非完全不能见，错误；B选项：原文要求10点前睡觉，错误；C选项：原文禁止在教室吃喝，错误；D选项：家庭规则和学校规则都明确规定不能大声说话，符合原文，正确，故选D。
