安排学与生活时间，做自己的“时间管理师”：③家校协同，合理安排好学生的学任务：④改善教育生态，用更加科学、多元的教育评价机制减轻社会的教育焦虑，进而切实减轻中小学生学业负担，让更多孩子安心睡觉，拥有更加健康的成长环境。（言之有理、答到两点即可)(2)示例：这幅漫画发生的场景是在一个孩子的卧室，此刻早已是深夜，穿着睡衣的孩子抛下摆满了作业的书桌，准备上床睡觉。五本写有“功课”的书本面目狰狞地拦着孩子通往床上的路。寓意：中小学生课业负担过于繁重，严重影响了孩子们的睡眠。(3)示例：小明，适度地玩游戏，能帮助我们放松身心，但是熬夜玩游戏，就会给身心健康带来危害。比如长时间盯着电脑屏幕，眨眼次数减少，既容易引起千眼症，也容易导致近视发生。而且睡眠不充足，白天上课就会昏昏欲睡，这还怎么专心学呀？父母外出打工，你更应该做自己的“时间管理师”，少打游戏，保证充足的睡眠。四、心灵之约16.略
