14、的方法了。于是我就着手研究蛇的习性，以便能找到最容易的方法捉住它们。好在这些爬行动物都很小，问题比较容易解决。经过一番研究准备之后，我决定采用三种可能的方法：第一，铲除蛇的栖息地；第二，用男性或女性用的香水或食物把它们引进陷阱；第三，降低它们的体温，使它们困乏，这样就很容易把它们捉住。我决定采用最后一种方法。我买了一个制冰淇淋的不锈钢碗，在碗的内壁和外壁都抹上果冻，这些果冻冷却后会冻结。我把这个碗放进冰箱，冷冻了24个小时。与此同时，我还准备了一些冰块儿。第二天早晨太阳光还不太热，我就早早起床了。我把冰冻的碗放在蛇窝的上方，再把小冰块儿放在碗上，以使碗保持冷却状态，最后再用一个大桶把碗罩住。于

15、是我就等着。过了两个小时我才把桶和碗一起拿开。蛇不像以前那样活跃了，但是对于我来说，它们行动还是太快了，突然一下子就消失在附近的墙洞里去了。于是我只得调整我的计划。第二次试验我用的还是冻结的碗和冰块儿，但是这次我是在夜晚气温开始变凉的时候把它们放在蛇窝的上方，然后像以前一样用桶把碗罩住，通宵放在那儿。第二天一早我就去看结果。这一次我小心翼翼地蹲下去检查的时候，发现蛇都是睡意浓浓的。但是一把它们提起来，它们就要咬我。因为它们都是毒蛇，所以很显然我还得改进我的捕蛇方案。第三次试验重复了第二次的程序。第二天早晨我的手里拿了一个捕鱼的小网，这是因为我预料蛇还会再咬人。但是经过仔细的监视，证明这些蛇不会

16、惹麻烦，一切都按计划进行着。我把这些温顺的蛇收集起来，第二天就愉快地把他们全都释放到野外了。由于朋友和亲戚的敦促，我决定抓住这次机会把我的发明送到专利局去，请他们对我这次成功的思路给予认可。只有你得到这种承认，你才可以说是一个真正的发明家。(评定)专利标准非常严格，除非新的想法真是新颖的，否则很难被接受。此外，你的想法如果属于下列情况，那么你也不可能得到专利：一种发现一种科学理论或数学模式文学或艺术一个游戏或一笔交易一个电脑程序一种新的动植物物种你的产品要经过仔细调查，证明它确实是与众不同的，你才能获得专利。专利局还有一大批审查人员，他们的唯一职责就是审查你的专利申请是否有效。如果通过了所有的

17、这些审查，你申请的专利就会在你提出申请的18个月之后公布出来。于是，我填了表，向专利局提交了申请书。现在就是等待和期盼了。将来你看看我的银行结余金额就会知道我是否成功了。祝我好运吧！二、将下列词语译成英语，然后参考Unit 3的词汇表自主勘误。1专利证书，专利权n._2抓住，捉住，夺 v._3忍耐，忍受，负担v.&n._4轻打，轻敲，水龙头v.&n._5文件，档案，归档 n.&v._6产品 n._1patent2.seize3.bear4.tap5.file6.product7.着手_8.一心投入，迅速把手伸入_9不挂断，稍等，紧握_10次序颠倒，发生故障_11设法联系上，通过_12挂断电话_
