9、pply for a patent.答案15BHGED68CAFTHE PROBLEM OF THE SNAKESWhen I called up my mother in the countryside on the telephone she was very upset.“There are some snakes in our courtyard(院子),”she told me.“Snakes come near the house now and then,and they seem to have made their home here,not far from the wal

10、nut(胡桃) tree.Can you get rid of them please?”I felt very proud.Here was a chance for me to distinguish myself by inventing something merciful that would catch snakes but not harm them.I knew my parents would not like me to hurt these living creatures!The first thing I did was to see if there were an

11、y products(产品)that might help me,but there only seemed to be powders(粉末)designed to kill snakes.A new approach was clearly needed.I set about researching the habits of snakes to find the easiest way to trap them.Luckily these reptiles are small and that made the solution easier.蛇的困扰我给住在乡下的母亲打电话的时候,她

12、感到很心烦。“我们院子里有几条蛇,”她告诉我,“蛇时不时地爬到屋子边上来,似乎是在屋子附近离胡桃树不远的地方安家了。你能不能把它们赶走?”我感到很自豪。这回我有机会来表现一下自己了。我要发明某种仁慈的东西,既可以把蛇捉住,又不会伤害它们。我知道我的父母是不会让我伤害这些生物的!我所做的第一件事就是看看有没有什么产品能帮助我,但看来只有设计用来毒杀蛇的药粉。很明显,我得找一种新的方法了。于是我就着手研究蛇的习性,以便能找到捕蛇的最简易的方法。好在这些爬行动物都很小,这使得问题比较容易解决。助读讲解far from在句中意为“离远”,还可表示“远非;相差很远”,后接名词、动名词等。get rid

13、of 除掉,摆脱。Prepared with some research findings,I decided on three possible approaches:firstly,removing their habitat;secondly,attracting them into a trap using male or female perfume(香水)or food;and thirdly cooling them so that they would become sleepy and could be easily caught.I decided to use the l

14、ast one.I bought an icecream maker which was made of stainless steel.Between the outside and the inside walls of the bowl there is some jelly (果冻状物),which freezes when cooled.I put the bowl into the fridge and waited for 24 hours.At the same time I prepared some icecubes(小冰块)The next morning I got u

15、p early before the sun was hot.I placed the frozen bowl over the snakes habitat and the icecubes on top of the bowl to keep it cool.Finally I covered the whole thing with a large bucket.Then I waited.After two hours I removed the bucket and the bowl.The snakes were less active but they were still to

16、o fast for me.They abruptly disappeared into a convenient hole in the wall.So I had to adjust my plan.经过一番研究准备之后,我决定采用三种可能的方法:第一,铲除它们的栖息地;第二,用男人或女人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,在碗的内壁和外壁之间有些胶状物,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。第二天早晨在太阳光还不太热的时候我就早早起床了。我

17、把冷冻过的碗放在蛇窝的上方,再把冰块放在碗上,以使碗保持冷却状态。最后再用一个大桶把所有的东西罩住。然后我就等着。两个小时以后我把桶和碗一起拿开。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。它们突然就消失在附近的墙洞里去了。于是我不得不调整我的计划。助读讲解过去分词短语Prepared with作状语。现在分词短语using male作方式状语。which freezes when cooled是which引导的非限制性定语从句,补充说明jelly的作用。其中when cooled是时间状语从句的省略形式,补充完整为when it is cooled。For the second

18、 attempt I froze the bowl and the icecubes again but placed them over the snakes habitat in the evening,as the temperature was starting to cool.Then as before,I covered the bowl with the bucket and left everything overnight.Early the next morning I returned to see the result.This time with great cau

19、tion I bent down to examine the snakes and I found them very sleepy.But once picked up,they tried to bite me.As they were poisonous snakes,I clearly needed to improve my design again.My third attempt repeated the second procedure.The next morning I carried in my hand a small net used for catching fi

20、sh.This was in the expectation that the snakes would bite again.But monitored carefully,the snakes proved to be no trouble and all went according to plan.I collected the passive snakes and the next day we merrily released them all back into the wild.第二次尝试我又一次冷冻了碗和冰块,但是这次我是在夜晚气温开始变凉的时候就把它们放在蛇窝的上方,然后像

21、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,发现它们都是睡意浓浓的,但是一旦把它们提起来,它们就试图咬我。因为它们都是毒蛇,所以很显然我还得改进我的捕蛇方案。第三次尝试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。但是经过仔细监视,证明这些蛇是制造不了麻烦的,一切都按计划进行着。我把这些温顺的蛇收集起来,第二天就愉快地把它们全都释放到野外了。助读讲解as引导的原因状语从句。过去分词短语monitored carefully作状语。Pressed by my friends and relations,I

22、 decided to seize the opportunity to get recognition(认可)for my successful idea by sending my invention to the patent office.Only after you have had that recognition can you say that you are truly an inventor.The criteria(评判的)标准are so strict that it is difficult to get new ideas accepted unless they

23、are truly novel.In addition,no invention will get a patent if it is:a discoverya scientific idea or mathematical modelliterature or arta game or a businessa computer programmea new animal or plant varietyNor will you receive a patent until a search has been made to find out that your product really

24、is different from everyone elses.There are a large number of patent examiners,too,whose only job is to examine whether your claim (要求)is valid(有效的)or not.If it passes all the tests,your application for a patent will be published 18 months from the date you apply.So I have filled in the form and file

25、d my patent application with the Patent Office.Now its a matter of waiting and hoping.Youll know if I succeed by the size of my bank balance!Wish me luck!在朋友和亲戚的敦促下,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。只有你得到这种认可之后,你才可以说自己是一个真正的发明家。(评定)标准是很严格的,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

26、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存款的金额就会知道我是否成功了!祝我好运吧!助读讲解过去分词短语“Pressed by my friends and relations”作原因状语。“only状语(从句)”位于句首时,句子(主句)需用部分倒装。Nor will you r

27、eceive a patent until a searchto find out that是主从复合句。nor位于句首,主句需用部分倒装;从句是until引导的时间状语从句,从句中又包含that引导的宾语从句。else经常用在特殊疑问词(如what)或复合不定代词(如everyone)之后;若有所有格形式,则把s放在else后。whose引导的定语从句,修饰patent examiners。该定语从句中,动词不定式to examine作表语,whether引导宾语从句。第一步速读了解文章主题和段落大意.速读P2021教材课文,匹配段落大意1Part 1(Para.1)AThe attempt
