[EX Q]: Article: These days, if you still think the cellphone is just for talking, you will get laughed at. Yes, it's true, voice-only handsets have become out of date. Today's do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minutes to use them. Some of the things a cellphone can do for you will be available this year:          Surf at speed          Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150.          Listen as you go          The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens.          Say cheese          Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video.          Portable TV          You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee.          The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator... So what is there that a cellphone can't do?

[EX Q]: Article: When a group of children politely stop a conversation with you, saying: "We have to go to work now," you're left feeling surprised and certainly uneasy. After all, this is the 1990s and the idea of children working is just unthinkable. That is, until you are told that they are all pupils of stage schools, and that the "work" they go off to is to go on the stage in a theatre. Stage schools often act as agencies to supply children for stage and television work. More worthy of the name "stage school" are those few places where children attend full time, with a training for the theatre and a general education. A visit to such schools will leave you in no doubt that the children enjoy themselves. After all, what lively children wouldn't settle for spending only half the day doing ordinary school work, and acting, singing or dancing their way through the other half of the day? Then of course there are times for the children to make a name and make a little money in some big shows. Some stage schools give their children too much professional work at such a young age. But the law is very tight on the amount they can do. Those under 13 are limited to 40 days in the year; those over 13 to 80 days. The schools themselves admit that not all children will be successful in the profession for which they are being trained. So what happens to those who don't make it? While all the leading schools say they place great importance on children getting good study results, the facts seem to suggest this is not always the case.

 Options: (A) attend a stage school (B) are going to the theatre (C) have got some work to do (D) love singing and dancing
