    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】

    电视剧《人民的名义》的热播,成为时下全民热评的主题。一部电视剧再次带动了全社会对腐败问题的关注,也提醒我们党的反腐决心是坚韧不拔的。众所周知,我党历来高度重视自身廉政建设。阅读材料,思考问题:

    材料陕甘宁边区政府十分重视建立和完善惩治腐败的法规建设。1938年8月先期公布了《陕甘宁边区惩治贪污暂行条例草案》,试行一段时间后,于1939年正式颁布。1943年正式制定颁布《惩治贪污条例》。规定:边区所属之机关部队及公营企业之人员、群众组织及社会公益事务团体之人员,有下列行为之一者。即以贪污论罪:(1)克扣或截留应当发给或缴纳财物者。(2)买卖公物,从中舞弊者;(3)盗窃侵吞公有财物者。(4)强占强征或强募财物者。(5)意图营利,贩运违禁或漏税物品者。(6)擅移公款,作为私人营利者。(7)违法收募捐税者。(8)伪造或虚报收支账目者。(9)勒索敲诈收受贿赂者。(10)为私人利益而浪费公有之财物者。该文件还规定了具体惩处标准:(1)贪污数目在1000元以上者,处以死刑。(2)贪污数目在500元以上者,处5年以上有期待或死刑。(3)贪污在300元以上500元以下者,处3年以上5年以下有期徒刑。(4)贪污在100元以上300元以下者,处1年以上3年以下有期徒刑。(5)贪污100元以下者,处1年有期徒刑或苦役,并追缴其贪污所得财物。

    除了依法惩贪制度外,边区政府还制定了干部管理教育制度、民主监督制度、精简机构和俸以养廉制度。
