河北省武邑中学2016届高考英语一轮复习 unit3 inventors and inventions导学案 新人教版选修8readingwhen i called up my mother in 1._ countryside on the telephone she was very upset. “there are some snakes in our courtyard,” she told me. “snakes come near the house now and then, and they seem to have made their home here, not far 2._ the walnut tree. can you get rid of them please?” i felt very proud. it was a chance for me to distinguish myself by inventing something 3._ (mercy) that would catch snakes but not harm them. i knew my parents would not like me4._ (hurt) these living creatures!the first thing i did was to see if there were any products that might help me, but there only seemed 5._ (be) powders 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. 6._ (lucky), these reptiles are small that made the solution easier.7._ (prepare) 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 or food; and thirdly cooling them so that they would become sleepy and could 8._(catch) easily. i decided to use 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 9._(freeze) 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 second 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 10._(see) the result. this time with great caution i 11._ (bend) down to examine the snakes and i found them very 12._(sleep). 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 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 released them all back into the wild.pressed by my friends and relations, i decided to seize the opportunity to get recognition 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 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 varietynor will you receive a patent until a search has been made to find out that your product really is different from everyone elses. there are a large number of patent examiners, too, 13._ only job is to examine whether your claim is valid 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 filed 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!alexander graham bellalexander graham bell was born in 1847 in scotland, but when he was young his family moved to boston, usa. his mother was almost 1._ (entire) 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 mothers forehead, he could make her 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 seen before. follow it up, explore all around it, and before you know it, you will have something worth 2._ (think) about to occupy your mind. all really big discoveries are the result of thought.”it was this exploring around problems and his dynamic spirit _ led to his most famous invention the telephone in 1876. bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. this original telegraph sent a message over distances using morse code (a series of dots tapped out along a wire in a particular order). but only one message could go at a time. bell wanted to improve it so that it could send several messages at the same time. he designed a machine that would separate different sound waves and allow different conversations to be held at the same time. but he found the problem difficult 3._ (solve). one day as he was experimenting with one end of a straw joined to a deaf mans ear drum and the other to a piece of smoked glass, bell noticed when he spoke into the ear, the straw drew sound waves on the glass. suddenly he had a flash of inspiration. if sound waves could be reproduced in a moving electrical current, they could be sent along a wire. in searching to improve the telegraph, bell had invented the first telephone!bell was 4._ (full) aware of the importance of his invention and wrote to his father:“the day is coming when telegraph wires will be laid on to houses just like water or gas and friends will talk to each other 5. _ leaving home.”the patent was given in 1876, but it was not until five days later that bell sent his first telephone message to his assistant watson. the words have now become famous:“mr watson come here i want to see you.”alexander graham bell was not a man to rest and he interested himself in many other areas of invention. he experimented with helicopter designs and flying machines. while searching for a kite strong enough to carry a man into the air, bell experimented putting triangles together and discovered the tetrahedron shape. being very stable, it has proved invaluable in the design of bridges.bell was an inventor all his life. he made his first invention at eleven and his last at seventy-five. although he is most often 6. _（associate） with the invention of the telephone, he was indeed a continuing searcher after practical solutions to improve the quality of everybodys life.重点词汇1.seize v. vt. 抓住；夺取；理解；逮捕 1) he seized the thief by the arm.2)youll surely regret if you dont seize the opportunity 抓住机会.bob seized on/upon the rain as an excuse for missing school. 抓住， 利用2.
