The Problem Of The Snakes
龙男
When I called up my mother in the countryside on the telephone she was very upt. "There are some snakes in our courtyard," she told me. "Snakes come near the hou now and then, and they em to have made their home here, not far from the walnut tree. Can you get rid of them plea?" I felt very proud. Here was a chance for .me to distinguish mylf by inventing something merciful that would catch snakes but not harm them. I knew my parents would not like me to hurt the living creatures!
陈小艺的电视剧The first thing I did was to e if there were any products that might help me, but there only emed to be powders designed to kill snakes. A new approach was clearly needed. I t about rearching the habits of snakes to find the easiest way to trap them. Luckily the reptiles are small and that made the solution easier.
Prepared with some rearch findings, I decided on three possible approaches: firstly, removing their habitat; condly, attracting them into a trap using male or female perfume or food; and thirdly cooling them so that they would become sleepy and could be easily cau
ght. I decided to u the last one. I bought an ice-cream maker which was made of stainless steel. Between the outside and the inside walls of the bowl there is some jelly, which freezes when cooled. I put the bowl into the fridge and waited for 24 hours. At the same time I prepared some ice-cubes.
The next morning I got up early before the sun was hot. I placed the frozen bowl over the snakes' habitat and the ice-cubes 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 too fast for me. They abruptly disappeared into a convenient hole in the wall. So I had to adjust my plan.

For the cond attempt I froze the bowl and the ice-cubes 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 e the result. This time with great caution 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 cond procedure. The next morning I carried in my hand a small net ud for catching fish. 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 relead them all back into the wild.
Presd by my friends and relations, I decided to ize the opportunity to get recognition for my successful idea by nding my invention to the patent office. Only after you have had that recognition can you say that you are truly an inventor. The criteria are so strict that it is difficult to get new ideas accepted unless they are truly novel. In addition, no invention will get a patent if it is:
a discovery
a scientific idea or mathematical model
literature or art

a game or a business
a computer programme
a new animal or plant variety
Nor will you receive a patent until a arch has been made to find out that your product really
is different from everyone el's. There are a large number of patent examiners, too, who only job is to examine whether your claim is valid or not. If it pass 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 filed my patent application with the Patent Office. Now it's a matter of waiting and hoping. You'll know if I succeed by the size of my bank balance! Wish me luck!

ALEXANDER GRAHAM BELL
手动挡和自动挡的区别
怎么面对面建群 Alexander Graham Bell was born in 1847 in Scotland, but when he was young his family moved to Boston, USA. His mother was almost entirely deaf, so Alexander became interested in helping deaf people communicate and in deaf education. This interest led him to invent the microphone. He found that by pressing his lips against his mother's forehead, he could make his mother understand what he was saying.
He believed that one should always be curious and his most famous saying was:
"Leave the beaten track occasionally and dive into the woods. Every time you do you will be certain to find something that you have never en before. Follow it up, explore all around it, and before you know it, you will have something worth thinking about to occupy your mind. All really big discoveries are the result of thought."
