Unit 1 Living with technologyTechnology Creates or Solves Problems?人类文明受技术的影响从未像今天这样强烈，卫星、克隆和互联网都是很好的例子。

当然，技术也带来了一些新的问题，关键是让技术通过自身发展克服它们。

It seems that human civilization has never been as fueled by technology as it is today.Satellites，Cloning and Internet are all examples of technology that has reshaped our life to an unprecedented degree.What matters most nowadays is that the power of technology must be ensured to overshadow the curses it brings about.It must be pointed out that technology can aggravate existing problems that are far from its original target.Atomic energy is just the case in point.Although its researches have a view of optimizing the current energy sources，atomic technology is repeatedly employed to manufacture deadly weapons for the purpose of deterring or even destroying other countries.Technology can also create new problems without alleviating the previous ones.There is no better example than the automobile.Wasn't it the inventor's promise that automobiles could bring speed and convenience to their owners，thus surpassing the other means of transportation? But every morning at rush hours，car owners enjoy neither speed nor convenience from car ownership.Meanwhile car exhaust remains an alarming effect on our environment.Therefore，technology is by no means a “cure­all” solution.Yet there is no need to use the above reasons as excuses to stop the development of technology.The key is to control the problems and allow the technology to overcome them through self­advancement.[阅读障碍词]1．unprecedented adj.前所未有的2．overshadow vt.遮挡3．aggravate vt.使严重4．optimize vt.充分利用5．deter vt.制止6．alleviate vt.缓解[诱思导读]1．What does atomic technology bring us according to the passage?It can let people make full use of the current energy sources but it also helps manufacture deadly weapons.2．What is your opinion of technology?Technology can not only bring development of human civilization but also cause problems.We should learn how to control and solve the problems.Section ⅠReading (Ⅰ)(Welcome to the unit & Reading)Ⅰ.匹配下列单词的词性及汉语意思( )1.evolution A．vt.制造；修筑，建造( )2.principle B．n.演变，发展；进化( )3.receiver C．n.原理，法则；道德原则，行为准则( )4.wind D．n.无线电接收机；听筒，受话器；接受者( )5.construct E．vt.& vi.上发条；缠绕；蜿蜒，曲折( )6.portable F．n.专利权；专利证书( )7.digital G．vt.播放，转播；接转，转发n．接力赛；中继设备( )8.storage H．adj.便携式的，轻便的( )9.patent I．adj.数字信息系统的，数码的，数字式的( )10.relay J．n.存储，储藏(空间)[答案] 1－5 BCDEA 6－10 HIJFGⅡ.选择下列句中词组的汉语意思( )2.Only then did we realize that our economy had benefited from the new technologies greatly.( )3.This horse is too weak to keep pace with the others.( )4.With the help of the charity，the children can have access to the Internet.( )5.We hope your suggestion will contribute tosolving the problem.( )6.It would be better to rely on ourselves than on others.[答案] 1－6 CADFBEThe evolution of video and sound devices(设备) Early history of TVThe first public TV broadcasts were made in the USA in ter，in 1928，the first long­distance TV broadcast was made between the UK and the USA.Regular public broadcasting followed shortly afterwards，first beginning on 11 May 1928 in New York and on 20 August 1929 in London①.Many different people contributed to the development of TV.Most early TV broadcasts were made using a system developed by John Logie Baird②in the UK.However，his system was very primitive and had many drawbacks(缺点)．An American，Philo Farnsworth，made important breakthroughs in the development of TV in the late 1920s and early 1930s.Modern TVs use many of the principles first discovered by Farnsworth.John Logie Baird constructed the first colour TV in 1928，but it was not until 1938 that the first colour TV programme was broadcast③.It took more than two decades，though，until 1951，for regular colour TV broadcasts to begin in the USA.Regular colour TV broadcasts were delayed(使推迟) in the UK until 1967.However，within a short time nearly all TV broadcasts were made in colour，and within five years more colour TVs than black­and­white(黑白的) TVs were being used.影像和声音设备的发展电视的早期历史无线电视传输节目于1925年在美国首次公开播出。

Unit 1 Living with technology Section Ⅰ Welcome to the unit& Reading-Pre readingAt some point we all have to face reality: we can't live off our parents forever. We have to get a job and become a productive member of society or earn a living as a writer. That time has come for French robot Nao, who has left Paris to get his first job at a bank in Japan.Nao is a smart bank teller. He is just 58cm tall and weighs about 5.4 kg. He speaks 19 languages and can read customers' emotions from their facial expressions thanks to the built­in camera in his head. He can walk on different surfaces, recognize faces and objects, express feelings and react to touch. It can even balance itself with its arms if it falls. He can greet visitors and offer them all of the services in a bank.“The robot is an important addition to the bank by performing tasks that our human staffcan't, such as 24­hour banking and multilingual communication. He is cute and friendly and I believe our customers will like it，” said an official.The bank believes that Nao's superb linguistic skills and ability to work for 24 hours a day will be invaluable, especially during the 2020 Summer Olympic Games, when the country expects to welcome visitors from around the world.Nao enjoys a wide range of hobbies, including playing golf and dancing. For example, he can dance to the song GangnamStyle by moving its arms and legs.Section_ⅠWelcome to the unit & Reading —Pre­reading[原文呈现][读文清障]The evolution① of video and sounddevices②Early history of TVThe first public TV broadcasts were made in the USA in 1925.

Unit 1 Living with technology-Reading Reading TV and audio devices: a reviewStep 1: Lead-inNew technology is often used in old ways. Fill in the following chart:Technology UsageComputerUsed as a typewriter/tape recorder/VCD player/notebook/calendar/telephone/calculator.The InternetUsed as alibrary/magazine/TV/telephone/bank/store.CellphoneUsed as atelephone/watch/calendar/camera/computer.Meanwhile, with the development of science technology, more functions are added to electric products. Look at the picture: Have you ever seen such a mouse before?What function do you think it has? (It can also act as a CD player)What functions do you need in a TV set or an audio device?Are you interested in the development of TV and audio devices? Today, we are going to read a passage about this topic.Step 2: Fast reading for general ideasGo through the passage as quickly as possible and try to find answers to the three questions in part A on Page 2. Just focus on and identify the information needed to answer thesequestions.Step 3: Detailed reading for important information1.Let’s read the passage a second time and complete PartsC1 and C2 on page 4.2. Listen to the tape and try to correct the wrong sentences in Part C1:3. Read the text again and choose the best answers according to the text:1) When and where was the first long-distance TV broadcast made?A. In 1925 in the USA.B. In 1926 in the UK.C. In 1928 in the UK.D. In 1928 in both the USA and the UK.2) Who might be the inventor of the first T V?A. Vladimir Zworykin from Russia.B. Philo Farnsworth in the USA.C. John Logie Baird from Scotland.D. It remains uncertain.3) How many countries have put digital TV into operation according to the passage?A. Only one.B. Already two.C. At most three.D. At least four.4) Who might have attributed to the development of the Walkman?A. Two Japanese engineers.B. Three American scientists.C. Thomas Edison.D. Emile Berliner.5) What is the main factor that causes the spring up of musicwebsites all over the Internet?A. The popularity of Walkman.B. The development of the MD player.C. The development of MPs technology.D. The wide use of Discman.6) How is the passage organized ___________________.A. by paragraphsB. in chronological orderC. by conceptsD. by sub-topicsNow, read the Reading strategy on page 3. Attention: subtitles appear after titles and provide more information about the text and subtitle can show how a text is organized. Read the passage again and figure out how this text is organized.TV Early history of TV(In order of time) The modern age: Cable TV, satellite TV, digital TV,…Audio devices Early history of audio devices(By types of equipment) Tape recorders and playersSounds goes digitalWhich of the following best shows the structure of theA. TB. TC. TD. T(T =title ①= subtitle 1 ②= subtitle 2 ③= subtitle 3 ④= subtitle 4 ⑤= subtitle 5 )Now we can see that the reading passage is mainly organized in chronological order. A timeline or a time chart may help you understand the text better. Could you make a timeline by yourselves?Step 4: Practice:1. Besides the reading strategy, I ’d like to give you another tip on reading. Do not refer to the dictionary every time you come across a new word. Just guess the meaning from the context. It is very important to read the sentences before and after the sentence which contains the unknown word. From the information before and after, you should be able to guess the meaning of the word. Now let ’s complete Parts D on page 4.①② ④ ⑤ ③ ①② ③④ ⑤ ①② ③④ ⑤ ①② ③④ ⑤D 1 e 2 d 3 h 4 c 5 g 6 f 7 a 8 b2. Wang Li attended a media technology exhibition and after that he gives a report to his classmates about it. Read it in Part E and fill in the blanks with words given in the box.AnswersE (1) wireless (2) broadcasting (3) Britain (4) 65(5) 200 (6) households (7) recording (8) recorders(9) compact (10) GermanyStep 5: Post-reading activities1. Pair work:Choose one of the greatest inventions in human’s history that you are most familiar with. Try to tell your partner about its development. Remember that you should organize your reporter in order of time.For referenceA Quick History of BicyclesThe Walking MachineIn 1817 Baron von Drais invented a walking machine that wouldhelp him get around the royal gardens faster: two same-sizein-line wheels, the front one steerable, mounted in a frame which you straddled.The device was propelled by pushing your feet against the ground, thus rolling yourself and the device forward in a sort of gliding walk. The machine became known as the Draisienne or hobby horse. It was made entirely of wood. This enjoyeda short lived popularity as a fad, not being practical for transportation in anyother place than a well maintained pathway such as in a park or garden.The Velocipede or BoneshakerThe next appearance of a two-wheeled riding machine was in 1865,when pedals were applied directly to the front wheel. Thismachine was known as the velocipede ("fast foot"), but waspopularly known as the bone shaker, since it was also madeentirely of wood, then later with metal tires, and thecombination of these with the cobblestone roads of the day madefor an extremely uncomfortable ride. They also became a fad,and indoor riding academies, similar to roller rinks, could befound in large cities.The High Wheel BicycleIn 1870 the first all metal machine appeared. (Previous to thismetallurgy was not advanced enough to provide metal which was strong enough to make small, light parts out of.) The pedals were still attached directly to the front wheel with no freewheeling mechanism. Solid rubber tires and the long spokes of the large front wheel provided a much smoother ride than its predecessor. The front wheels became larger and larger as makers realized that the larger the wheel, the farther you could travel with one rotation of the pedals. You would purchase a wheel as large as your leg length would allow. This machine was the first one to be called a bicycle ("two wheel"). These bicycles enjoyed agreat popularity among young men of means (they cost an averageworker six month's pay), with the hey-day being the decade ofthe 1880s.The High Wheel TricycleWhile the men were risking their necks on the high wheels, ladies, confined to their long skirts and corsets, could take a spin around the park on an adult tricycle. These machines also afforded more dignity to gentlemen such as doctors and clergymen. Many mechanical innovations now associated with the automobile were originally invented for tricycles. Rack and pinion steering, the differential, and band brakes, to name a few!The High Wheel SafetyImprovements to the design began to be seen, many with the small wheel in the front to eliminate the tipping-forward problem. One model waspromoted by its manufacturer by being ridden down the frontsteps of the capitol building in Washington, DC. These designsbecame known as high-wheel safety bicycles. Since the olderhigh-wheel designs had been known simply as bicycles, they werenow referred to as "ordinary bicycles" in comparison with thenew-fangled designs, and then simply as "ordinaries."The Hard-Tired SafetyThe further improvement of metallurgy sparked the next innovation, or rather return to previous design. With metal that was now strong enough to make a fine chain and sprocket small and light enough for a human being to power, the next design was a return to the original configuration of two same-size wheels, only now, instead of just one wheel circumference for every pedal turn, you could, through the gear ratios, have a speed the same as the huge high-wheel. The bicycles still had the hard rubber tires, and in the absence of the long, shock-absorbing2. Group work:Undoubtedly, in the future, both TV and audio devices will still play a very important role in human’s life. But they’ll certainly be advanced than those of today. Let’s work in pairs and design future TVs or audio devices.3. Let’s come to Part F. Work in pairs and share your opinions with each other.4.
