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?
A. The high speed Internet connection. B. Many free Internet phones.
B. Using the same computers for Internet phones when you go to other places. C. Used in all the US cities. Some scientists started to call Wi-Fi 4G, because_____.
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. |
D.Wi-Fi will surely take the place of the mobile phone network. |
. Which of the following is the best title?
A.Third Generation Telecommunication Technology
B. Free Call Service
C.Google Launches Free Wi-Fi Service
D.Free Wi-Fi Service across the U.S.A.

The 9.2一magnitude(震级)earthquake which caused the tsunami in
the Indian Ocean on Boxing Day last year occurred at 7:58 a.m.,95 miles off the west coast of Aceh, Indonesia.
Eighteen minutes later.10-metre high waves crashed the ashore along a 500——mile-long stretch of Aceh.
Two hours later the tsunami hit Thailand and Malaysia and then Burma, Bangladesh, India,the Maldives,Sri Lanka,Kenya and Somalia.The final death toll is thought to be about 280,000,with tens of thousands more listed as missing.More than l.8 million people lost their homes.
●What Is Tsunami?
A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes,volcanic eruptions(爆发),or even the collision of meteorites(陨星).Tsunamis are also incorrectly known as tidal waves,but unlike tidal waves they are not caused by changes in the tides.
They are also most common around the edge of the Pacific,where more than half of the world’s volcanoes are found.These fast moving waves can attack coastlines,often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried l 80m inland.
●Wave Power
Atsunami can have a wavelength in excess of(超过)1 00km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea.
Over the deep Pacific Ocean,a tsunami travels at about 800kph.If an earthquake happened in Los Angeles.a tsunami could hit Tokyo quicker than you could fly between the cities by jet.
●Strange Animal Behaviors
Ten days before giant waves slammed into Sri Lanka and India coastlines,wild and domestic(家养的) animals seemed to know what was about to happen and fled(逃跑)to safety.
Elephants screamed and ran for higher ground.

Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943.
In 1967, Tasmania experienced a drought(干旱). The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Vi
ctoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.
Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals(节日). For example, in 1992, Tasmania extended(延长)daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games.
The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television.. Daylight Saving Time was introduced in Tasmania _______________.
A.to stop the drought in 1967 | B.to support government officials |
C.to pass a special law in the state | D.to save water and electricity |
.. What can we learn about DST in some Australian states?
A.It doesn’t have fixed dates. | B.It is not used in festivals. |
C.Its plan was changed in 2000. | D.It lasts for two weeks |
.. What do we know about the use of DST from the last paragraph?
