【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。

    For years I wanted a garden.I'd spend hours thinking of different things I could plant that would look nice together.
But then we had Matthew, and Marvin, and the twins Alisa and Alan, and then Helen.I was too busy raising them to grow a garden.
Money was not enough.Neither was time.Often when my children were little, one of them would want something that cost too much, and I'd have to say, “Do you see a money tree outside? Money doesn't grow on trees, you know.”
    Finally, all the children got through high school and college and were off on their own.I started thinking again about a garden.
Then, one spring morning, on Mother’s Day, I was working in my kitchen.Suddenly, I looked out of the window and there was a new tree, planted right in my yard.There were things blowing around on it.Then I put my glasses on—and I couldn't believe what I saw.There was a money tree in my yard!
    I went outside to look.It was true! There were dollar bills(帐单), one hundred of them, hanging all over that tree.There was also a note among them, “Thank you for your time, Mom.We love you!”
    Later, my children bought me tools, ornaments, a sunflower stepping stone and gardening books.A new page started in my life.
That was three years ago.My garden's now very pretty, just like I wanted.When I go out and take care of my flowers, I don’t seem to miss my children as much as I once did.It feels like they're right there with me.Now every year when winter comes, I look out of my window and think of the flowers I'll see next spring in my little garden.I think about what my children did for me, and I get tears in my eyes—every time.
I'm still not sure that money grows on trees.But I know love does!
