The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.
Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.
A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.
The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.
Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.
In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.
Wi-Fi is not available in cities without_____.
A. a computer B. a radio C. a hotspot D. a cell phone
Which of the following is NOT the advantage of Wi-Fi?
The high speed Internet connection. B. Many free Internet phones.

A.it is the product of the Google”s 4th generation.
B..it is more capable of sending information than the mobile phone network.
C.it has been used by more than four generations.

In the photo, she is walking up the steps of the William Frantz Public School in New Orleans, a little black girl accompanied by two officers who protect her on her way to school.
Her name then was Ruby Nell. It was Nov. 14, 1960. She was the first black child to enroll at this all-white elementary school according to the court order to desegregate in New Orleans schools. Her story is moving -- she was a very courageous child -- and remains a significant proof against intolerance (不宽容) of all kinds. Ruby’s photo brings out another powerful image on her website: Norman Rockwells symbolic painting for Look magazine on Jan. 14, 1964, “The Problem We All Live With.”
Rockwell was an illustrator of exceptional skill and charm. He produced a vast number of unforgettable images over a long career, many of them involving children. His American kids are innocent and appealing, but often, at the same time, decidedly naughty. His method was to photograph his models, and the resulting paintings were photographic. But it is revealing to see how the artist slightly changed facial expressions from photo to oil painting in order to make his paintings communicate with the viewer. Communication, even persuasion, lay at the back of his work; this was art for effect.
“The Problem We All Live With” belongs to Rockwell’s later work, when he began openly showing his strong belief in liberty. This is a highly persuasive image. Before he arrived at the final copy, one sketch (草图) shows the little girl closer to the two officers following her than to those in front. In the finished picture, the girl seems more determined, independent, and untouched. The unfriendly tomatoes thrown on the wall are behind her now, and she, is completely unaffected.
Ruby Nell was protected by officers on her way to school, because .
A.she was a little fighter against racism
B.she was very young, short and timid
C.she was the first black to study in an all-white school
D.she was chosen by the com t0be’wi’th white children
According to the passage, “The Problem We All Live With” is a(n) .
A.social program for American children
B.famous painting by Norman Rockwell
C.photo displayed on Ruby Bridges’ website
D.exhibition at the Norman Rockwell Museum
The word “desegregate” in paragraph 2 probably means“ ”.
A.fight against the white B.end racial separation
C.struggle for freedom D.stop the black-white conflict
The main topic of this passage is .
A.how Rockwell encouraged Ruby to fight against racism
B.how Ruby won her fight to go to an all-white school
C.how Rockwell expressed his protest in .Iris work
D.how persuasive Rockwell’s earlier work of art is

BEIJING—Apple Inc is one step closer to beginning sales of iPad3 tablet computers with cellular (手机) network compatibility (兼容) for the first time in the Chinese mainland, where the consumer-electronics giant is in the midst of an aggressive expansion.
According to China’s Telecommunication Equipment Certification Center, a device by Apple with third-generation high-speed wireless data capabilities was issued the network access license needed for the company to begin official sales in China. The device, listed under model number “A1396”, is compatible with the 3G standard WCDMA, and would work with the cellular network operated by Apple’s local iPhone partner, China Unicom (Hong Kong) Ltd.
China Unicom declined (谢绝) to comment.
Apple already offers the 3G iPad3 in Hong Kong through its partners, but currently only offers Wi-Fi versions of the device in the Chinese mainland. Still, consumers in China, which according to research firm IDC surpassed (超过) the US as the world’s largest PC market in the second quarter, have been purchasing 3G tablets through unofficial channels.
Separately, Apple spokeswoman Carolyn Wu said Sept 6 that the company’s first Hong Kong store, set to open this quarter, will be located in the city’s central shopping and business district in the International Finance Center’s upscale (高档的) IFC mall, a commercial center and sightseeing spot along the city’s waterfront. Wu also said that Apple is planning a new store in Shanghai later this quarter, which will be its biggest store in China. She declined to give more details or to comment on the 3G iPad3.
Apple currently has four full-service Apple stores in the mainland, which receive the most traffic of any Apple stores in the world. The company otherwise relies on resellers to get its products into the market.
The new stores reflect Apple’s confidence in rising demand for its products such as smart phones and tablet computers. Sales in the Chinese mainland, Hong Kong and Taiwan helped boost (增长) the company’s third-quarter results, newly appointed Chief Executive Tim Cook said in July. China revenue (收益) surged (激增) six-fold to about $3.8 billion during the three months ended June 25.
“This has been a substantial (重大) opportunity for Apple and I firmly believe that we’re just scratching the surface right now,” Cook said at the time, referring to strong sales in China. “I see an incredible opportunity for Apple there.”
