What if those new jeans you’ve just bought start tweeting(吱吱地叫) about your location as you cross London Bridge?
It sounds far-fetched, but it’s possible — if one of your coats is equipped with a tiny radio-frequency identification device (RFID), your location could be revealed without you knowing about it.
RFIDs are chips that use radio waves to send data to a reader — which in turn can be connected to the web.
This technology is just one of the current ways of allowing physical objects to go online — a concept called the “Internet of things”, which industry insiders have shortened to IoT.
This is when not only your PC, tablet and smartphone can connect to the web, but also your car, your home, your baseball cap and even the sheep and cows on a farm.
Smart buildings and intelligent cars with assigned IP addresses are already making cities smarter — and soon enough, the entire planet may follow.
“A typical city of the future in a full IoT situation could be a place with smart cameras everywhere, neurosensors (神經(jīng)監(jiān)測系統(tǒng)) scanning your brain for over-activity in every street,” says Rob van Kranenburg, a member of the European Commission’s IoT expert group.
This vision might still be years off, but one by one, “smarter” cities are beginning to crop up around our landscape.
IoT advocates claim that overall interconnectivity would allow us to locate and monitor everything, everywhere and at any time.
“Imagine a smart building where a manager can know how many people are inside just by which rooms are reflecting motion — for instance, via motion-sensitive lights,” says Constantine Valhouli from the Hammersmith Group, a strategy consulting firm.
“This could help save lives in an emergency.”
But as more objects go into the digital world, the fine line that separates the benefits of increasingly smart technology and possible privacy concerns becomes really blurred.
“The IoT challenge is likely to grow both in scale and complexity as seven billion humans are expected to coexist with 70 billion machines and perhaps 70,000 billion ‘smart things’, with numbers invading the last fences of personal life,” says Gerald Santucci, head of the networked enterprise and RFID unit at the European Commission.
“In such a new context, the worries increase: to what extent can monitoring of people be accepted? Which principles should govern the deployment of the IoT?”
72. The first paragraph is used to ________.
A. introduce a new kind of jeans to readers
B. arouse readers’ interest in the RFID
C. draw readers’ attention to the new jeans
D. set an example of using the RFID
73. The underlined phrase “crop up” in Para. 8 can be replaced by “__________”.
A. appear B. cooperate C. develop D. change
74. What can we know about IoT?
A. A typical city in a full IoT situation has come into reality.
B. The application of IoT may invade people’s privacy.
C. The technology of IoT has saved lives in an emergency.
D. IoT has been largely used in many cities.
75. If this text continues, what would be discussed next?
A. Solutions of defending people’s privacy.
B. The development of the IoT.
C. The control on monitoring.
D. Smart technology’s disadvantages.

While I was in 9 th grade, I built a circuit (電路裝置) for the traffic system of our city. After getting the first prize. I got this valuable advice from my father; “Do whatever interests you, and don’t let the work challenge you, make sure you are challenging that work.”
I have always preferred the projects which are challenging and related to real life problems. I clearly remember building a shipping program several years ago. I divided the whole project into several small sections. When I understood it clearly, used my brainstorming skill on it, and gave some basic ideas. Then I asked my professor for help before jumping into coding (編碼). At first, I did not know how to ask questions correctly and always asked the question “How do I do it?” As I kept working and discussed with my professor, I became more comfortable and those “how ”questions soon turned into “what if I do this and that” types of questions.
It took me four days to write the code. The desire to solve the problem kept me sleepless all nights brainstorming in even greater details. Every time I saw my program running smoothly, I exploded with joy. I still remember the last day of my work. I was getting some problem and didn’t know what to do. At that moment, a man came in to clean. He has headphones, and he was dancing while cleaning the room. Seeing this, I burst out laughing. That moment calmed me. I regained energy and interest and started to work again, and soon I fixed the problem.
My success in the project proved that breaking up a large problem into small parts could help find a possible solution. Discussing the problem with others was also very beneficial. Now I have gained the confidence to attempt any kind of project.
59.According to the passage, the writer was interested in .
A.developing traffic systems
B.doing challenging projects
C.winning great prizes
D.writing different codes
60.The writer asked the question “how do I do it” at first because .
A.he had no clear idea about his program
B.he was too shy to express himself
C.he wanted to he understood easily
D.he preferred this kind of question
61.We learn from the passage that the writer’s shipping program .
A.would benefit people a lot
B.was done together with others
C.was difficult and needed patience
D.cost much money and energy
62.What would be the best title of the passage?
A.Do It Yourself

科目:高中英語 來源:浙江省舟山市2010屆高三高考模擬試題(英語) 題型:閱讀理解
第二部分:閱讀理解(第一節(jié)20小題,第二節(jié)5小題;每小題2分,滿分50分)
第一節(jié):閱讀下列短文, 從每題所給的四個(gè)選項(xiàng) (A、B、C和D) 中, 選出最佳選項(xiàng)。
Being interested in a theme park since the time that I was a child, I have learned a thing or two over the years about packing for a day of fun. A trip to a theme park is always a adventure, but if you’re not prepared, your day of fun could easily turn into a tiny little nightmare(噩夢). It is important to pack long sleeved(帶袖的) shirts or jackets for all members of your family. I is also a good idea to pack an extra pair of socks for each member of the family, especially the children, as those wonderful water rides can be fun, but wet socks that won’t dry aren’t so much fun.
You don’t want to pack too much food, as you will probably want to experience at least some of the food offered at the theme park of your choice(that’s half of the fun), but it’s always a good idea to bring some energy increasing snacks, such as fruit,trail mix,etc. This can mean the difference between spending a lot of money on snacks or a little money on one or two good meals.
Theme parks,while fun and exciting, can wear a person out,especially a child, so it’s important to keep hydrated(含水的). I would suggest packing one bottle of water per person, and possibly a couple of cans of soda or bottles of juice as well.
It’s a good idea to have at least two cell phones or even a set of “walkie-talkies” in the event that your family gets,separated in the park. It’s a good idea to give one of these things to the children and one to the parents and make sure that each of them knows how to use it. This could be the difference between trouble and a happy ending,
1.You should get well prepared before going to a theme park__________.
A. because the trip always costs much money
B.because there are always too many people in a theme park.
C. so as not to suffer from bad dreams when going back
D.so as to cut down your trip expenses and have more fun
2.From the passage, we can know_______________.
A.the author was fond of visiting theme parks when he was a child
B.wearing wet socks in a theme park will bring children much fun
C.it is terrible to have a taste of the food offered in a theme park.
D. we’d better bring enough food, clothing and water when going to a theme park
3.What does th underlined part”walkie-talkies” in the last paragraph probably refer to?
A. A kind of transportation tool B.A kind of musical instrument
C.A kind of CDplayer D.A kind of phone
4.How many types of things does the author advise us to pack for day trips to a theme park?
A Three B.Five C.Six D. Eight
