    The new iPhone 3G should please everyone. Its look and feel are only slightly improved, but a faster network loads Web pages more quickly, true GPS functionality allows it to easily find places nearby, and the new $199 price (down from $400) makes it an affordable luxury.

    Before deciding whether to buy, however, make sure you can actually take advantage of the iPhone 3G's high-speed data network. 3G stands for third-generation, which in non-geek speak translates to Web pages and mail messages that, ideally, load about three times faster than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf the Web at the same time. That's great, if you live or work in a place where the 3G network of AT&T（美国电话电报公司） (the sole wireless carrier of the iPhone) is active. That's not so great in cities like New York where AT&T's cellular coverage is awful. As one of my colleagues in New York City, who bought the original iPhone, commented, "It's just a toy. You can't make phone calls on it, so I carry my Verizon phone with me all the time."

    The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds of add-on applications that have been developed just for the iPhone. You'll find tons of games (I like JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you, but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you'll enjoy them a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews), Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location — provided by the iPhone 3G's GPS chip — to make recommendations. The apps also load much faster over the 3G network.

    The new iPhone 3G has following features except that _______

    A. It looks and feels better                                B. It has a faster network

    C. It is easy to locate a place                           D. It is too expensive for people to buy

    Why do one of my colleagues carry Verizon phone with him all the time? ______.

    A. Because iPhone 3G is just a toy.                                                 

    B. ecause he prefers Verizon phone better.

    C. Because AT&T's cellular coverage is terrible there

    D. Because Verizon phone enables him make a phone call and surf the Web at the same time

    Which of the following statements is NOT true according to the passage. ____.

    A. App Store will offer you great fun.                                              B. many apps have been developed for the iPhone.

    C. Most apps are very expensive.

    D. Pandora, Facebook, MySpace and the New York Times are popular websites.

    From the passage we know that the attitude of the author toward iPhone 3G is _____.

    A. doubtful                   B. appreciative              C. optimistic          D. pessimistic

    阅读理解
         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 (神经监测系统) 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 theIoT?"  

    1. 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

    2. The underlined phrase "crop up" in Para. 8 can be replaced by "______".
    A. appear
    B. cooperate
    C. develop
    D. change

    3. 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.

    4. 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.

    Over the past 10 years, technologies that have combined computers with telephones have developed. Technologies such as PC fax programs and LAN fax servers(局域网传真服务器) have been used to improve fax communications. The latest computer-based technologies are new mechanisms(机制) which use IP(Internet Protocol, 因特网协议) to send faxes, that is, IP fax.

    Traditional fax has a fairly simple usage model. First, the user inserts a document into the fax machine, enters the destination fax number and presses the start button on the machine. The sending machine dials the receiving fax machine. If it connects, the sending machine scans the documents and sends it over the public switched telephone network(PSTN, 公共电话交换网) to the receiving machine. At the same time, the receiving machine receives the document and then prints it.

    In IP fax system there are two basic transmission modes: store-and-forward mode and real-time mode. Store-and-forward mode has been widely used. In this mode, the entire document is sent to a network-based server that stores it and then sends it to the destination. Real-time IP faxing is similar to traditional fax. Real-time mode allows two fax machines to directly communicate through a proper standard.

    IP fax enables a fax document to be sent from one person to another. A fax machine or a computer can be used to send or receive the fax. IP fax also allows e-mail to be used to receive faxes. This would enable users to receive faxes anywhere, anytime with an internet fax address.

    1. The passage deals mainly with _______.

    A. PC fax　　　　 B. IP fax　　　　 C. information technology　 D. new machines

    2. In traditional fax, _______ can be used.

    A. even computers

    B. LAN fax servers　　

    C. e-mail 　　　

    D. only fax machines

    3. IP fax can use all of the following to send and receive a fax except _______.

    A. a fax machine

    B. a receiving machine

    C. a computer　　 　

    D. e-mail

    4. In real-time IP fax mode _______.

    A. two fax machines communicate directly　

    B. a network-based server is used

    C. users can receive faxes anywhere　　　

    D. the PSTN has to be used

    5. In paragraph 2, the word “inserts” can be placed by _______.

    A. prints　　 B. presses　 C. puts　　　 D. uses
