Broadband is used for high-speed Internet connections at a fixed monthly rate.It turns an exciting telephone line into a high-speed digital line capable of carrying data up to 40 times conventional modem speeds.Any download is available at the click of a mouse-there is no dial-up as there is with standard Internet Service Providers.
For home owners and families there are many advantages.One of the most important is simultaneous(同时的)access to both telephone lines and the Internet.No queses and no delay.
For businesses, broadband can improve customer relations and provide direct access to corporate e-malls and databases.Entire operations can go online.
1.The function that broadband technology has on the new digital economy is ___.
A.further
B.critical
C.costly
D.global
2.How much does a user pay if he has broadband technology installed？ ()
A.It depends on the length of time
B.It depends on the times of dial-up
C.He pays at a fixed monthly rate
D.He pays a lot of money
3.Compared with the modem speed the broadband technology can transmit data___.
A.at up to forty times of ordinary speed
B.much faster
C.at a high-speed
D.within a second
4.Who can take advantage of the broadband technology according to the passage？ ()
A.Family members
B.College students
C.Both home owners and businessmen
D.Only businessmen and their partners
15.With the broadband technology companies can have all their operations done()
A.during the work days
B.during the whole week
C.online
D.offline
第2题
Satellites have enabled immediate reporting worldwide.A reporter can send the news to a network like CBS News and within seconds it can be all over the world.They send electronic reports that go straight into the newspaper or onto the TV screen.Reporters can now also transmit images through their mobile phones.Consequently, live, “on-the-spot” reporting has become the norm and TV viewers can get a much better idea of what a natural disaster, a conflict or an interesting scientific discovery is like.
In recent years, several changes have occurred in the ownership of news media.Networks owned by large companies and governments have become bigger and very powerful.These networks – such as BBC News 24–are hungry for news and have huge audiences.However, there can only be a limited number of such networks and their ownership is a big issue.
Some companies not only own TV and radio networks but newspaper groups as well.Who decides what news to publish and what sort of “spin” to put on it？ Is it always objective？ There are now “spin doctors” who manipulate the news,emphasising certain parts and not others – and as a result, much of it is not neutral.Therefore, the question of control of the media matters very much.In some cases, the media companies are more powerful than governments.They can even influence elections.So the question is – should they be controlled and if so, by whom？
1.Immediate reporting has become possible all over the world because of().
A.reporters
B.the use of news networks
C.the use of satellites
D.the communications revolution
2.()has become the norm.
A.Electronic reports
B.Instant news
C.Live reporting
D.Transmitting images through mobile phones
3.In what ways are media companies powerful？ ()
A.They can influence elections in some way
B.Nowadays, the manipulation of news reports is possible
C.They not only own TV and radio networks but newspaper groups as well
D.All of the above
4.According to the passage, the big issue is ().
A.ownership of news networks
B.that there can only be a limited number of such networks like BBC News 24
C.that networks owned by large companies and governments have become bigger and very powerful
D.that the news reporting is manipulated by big companies
5.What can be inferred from this passage？ ().
A.The disadvantages of the communications revolution outweigh its advantages
B.We should put the question of control of the media on the agenda
C.The news reporting has always been objective
D.A reporter can send news directly to the audiences all over the world
第3题
Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms.In most nations, for example, weather – balloon observations are taken just once every twelve hours at locations typically separated by hundreds of miles.With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local events.
Until recently, the observation intensive approach needed for accurate, very short – range forecasts, or “Nowcasts,” was not feasible.The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome.Fortunately, scientific and technological advances have overcome most of these problems.Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost.Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information.Meteorologists and computer scientists now work together to design computer programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly.As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is becoming a reality.
11.The word “exceeded” in paragraph I most probably means ____________.
A.added up toB.were more than
C.were about D.were less than
12.Conventional computer models of the atmosphere fails to predict such a short – lived tornado because ______________.
A.the computer is not used to forecast specific local events
B.the computers are not advanced enough to predict it
C.the weather data people collect are often wrong
D.weather conditions in some small regions are not available
13.According to the passage, the word “Nowcast” (paragraph 3) means _______________.
A.a way of collecting raw weather data
B.a forecast which can predict the weather conditions in the small area in an accurate way
C.a network to collect instant weather data
D.a more advanced system of weather observation
14.According to the passage, ___________ is the key factor to making “Nowcasts” a reality.
A.scientific and technological advances such as radar, or satellites
B.computer scientist
C.meteorologists
D.advanced computer programs
15.According to the author, the passage mainly deals with ________________.
A.a tornado in Edmonton, Alberta
B.what’s a “Nowcast”
C.the disadvantage of conventional computer models of the weather forecast
D.a breakthrough in weather forecast
