         “不过也说不定是将军家的狗……”巡警把他的想法说出来，“它的脸上又没有写个……前几天我在将军家院子里看见过这样一条狗。”
         “没错儿，将军家的！”人群里有人说。
         “哦，……叶尔德林老弟，给我穿上大衣吧……好象起风了，挺冷……你把这条狗带到将军家里去，问问清楚。就说这条狗是我找着，派人送上的。告诉他们别再把狗放到街上来了。说不定这是条名贵的狗；可要是每个猪思子都拿烟卷戳到它的鼻子上去，那它早就毁了。狗是娇贵的动物……你这混蛋，把手放下来！不用把你那蠢手指头伸出来！怪你自己不好！ 
         “将军家的厨师来了，问他好了——喂，普洛何尔！过来吧，老兄，上这儿来！瞧瞧这条狗，是你们家的吗？”
         “瞎猜！我们那儿从来没有这样的狗！”
         “那就用不着白费工夫再上那儿去问了，”奥楚蔑洛夫说，“这是条野狗！用不着白费工夫说空话了。既然普洛何尔说这是野狗，那它就是野狗。弄死它算了。”
         “这不是我们的狗，”普洛何尔接着说，“这是将军的哥哥的狗。他哥哥是前几天才到这儿来的。我们将军不喜欢这种小猎狗，他哥哥却喜欢。” 
          “他哥哥来啦？是乌拉吉米尔•伊凡尼奇吗？”奥楚蔑洛夫问，整个脸上洋溢着含笑的温情，“哎呀，天！我还不知道呢！他是上这儿来住一阵就走吗？”
“是来住一阵的。”
          “哎呀，天！他是惦记他的兄弟了……可我还不知道呢！这么说，这是他老人家的狗？高兴得很……把它带走吧。这小狗还不赖，怪伶俐的，一口就咬破了这家伙的手指头！哈哈哈—…•得了，你干什么发抖呀！呜呜……呜呜……这坏蛋生气了……好一条小狗……”

关于标有“6V 3W”字样的小灯泡（忽略温度对灯丝电阻的影响），下列说法正确的是（   ）

    We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.

    The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.

    Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms(微生物)．If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

    With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth．Then he added the plastic powder and let the microbes work their magic for 3 months．Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control．Sure enough, the plastic exposed(暴露) to the live bacteria was 17% lighter than the control after six weeks.

    The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

    "Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me．One day, I got tired of it and I wanted to know what other people are doing with these plastic bags．The answer: not much．So I decided to do something myself." Said Daniel Burd.
