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(美國電話電報(bào)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.
【小題1】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 |
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 |
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. |
A.doubtful | B.a(chǎn)ppreciative | C.optimistic | D.pessimistic |

China Telecom has the widest coverage.All cities in China with telephone access and most countries in the world are open to China Telecom’s IP card.
China Unicom’s IP card can reach 29 cities nationwide and more than 130 countries and regions worldwide.Jitong IP can access(接通)12 cities in China and over 70 countries and regions worldwide.
China Netcom’s IP card can reach 14 cities in China and 149 countries and regions in the world.
China Mobile’s IP card is open to only six cities nationwide but can access more than 200 countries and regions worldwide.

科目:高中英語 來源: 題型:閱讀理解
Over the past 10 years, technologies that have combined computers with telephones have developed. Technologies such as PC fax programs and LAN fax servers(局域網(wǎng)傳真服務(wù)器) have been used to improve fax communications. The latest computer-based technologies are new mechanisms(機(jī)制) which use IP(Internet Protocol, 因特網(wǎng)協(xié)議) 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, 公共電話交換網(wǎng)) 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.

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

B. a network-based server is used
