My 17-year-old daughter went off to college and having her away from home brought back memories of watching Peter Pan when she was little. In the classic TV production, one scene in particular impressed me: when Mrs. Darling puts her children into bed. As she turns off the last of the night light, she takes one last look at the bedroom and says, “Dear night lights, protect my sleeping children.” As a mother, I know how much she loves her children.

    It has been several weeks since we took our daughter to college and she seems to be adjusting well after a short period of homesickness. For us, though, it's another story. Like most parents, I love checking in on my children at night. But now she's gone, and I find nighttimes the hardest. I miss her most at night.

    In my neighborhood, most of the parents whose kids are off to college are dealing with similar melancholy. My husband is filled with anxiety. One friend talked about getting this sick feeling in her stomach as she prepared for the college drop-off. We complained that many of us were too busy to truly enjoy being with our children while we had them.

    For us moms, seeing Toy Story 3 only made the sadness worse as we watched the character Andy, who is the same age as our kids, say goodbye to his childhood as he prepares to leave for college. And it's not just “first-time” parents like me. Two moms who have kids already well into college said the separation didn't get any easier. “You feel like something has been taken away from inside you” said one of them.

    I imagine things will get easier with time, especially as I see my daughter adjust to college life. Meanwhile, as I keep my cell phone close to me in bed and text my daughter goodnight and sweet dreams every night, I like to think that messages serve as a night light that keeps her safe.

【历史上重大改革回眸】阅读材料，回答问题

材料：契丹族是我国古代北方草原上的古老民族，“逐水草畜牧，居毡卢，环车为营。”当中原处于唐之后的五代十国分裂割据之际，契丹族凭借武力迅速在北方崛起。公元916年，耶律阿保机统一了契丹各部，正式宣布登基称帝，建立契丹国（后改称辽）。而此时中原地区烽烟四起，民不堪命，大批汉人离开故土，逃往相对安定的北方契丹地区。阿保机按照唐代的规制另置州县城郭令其居业，让汉人保持原有的生产生活习俗与制度，这就是头下军州。阿保机也“平诸第之机，弭兵轻赋，专意于农”。

    公元938年，辽太宗耶律德光正式从后晋接收了燕云十六州（今北京、天津全境，以及山西、河北北部地区）。契丹在此地最初采用的是民族高压政策，对占领区进行粗暴的掠夺和残杀，汉人纷纷起来进行反抗。之后辽太宗制定了南北面官制。“官分南北（官制分南面官、北面官），以国制（辽朝固有制度）治契丹，以汉制待汉人……北面治官帐、部族、属国之政；南面治汉人州县、租赋、军马之事。因俗而治，得其宜矣。”使得“燕蓟之地陷于胡虏且百年而忘南顾之心”，辽朝“自阿保机创业于其初，德光恢廓于其后，吞并诸蕃，割据汉界，南北开疆两千里，东西四千里，戒器之备，战马之多，前古未有，子孙继统二百三十余年。”
