[EX Q]: Article: VOIP stands for Voice Over Internet Protocol. It is also referred to as IP Telephony. It is another way of making phone calls, though the 'phone' part is not always present any more, as you can communicate without a telephone set. VOIP is especially popular with long distance calls. The main reason for which people are so massively turning to VOIP technology is the cost. VOIP is said to be cheap, but most people use it for free. Yes, if you have a computer with a microphone and speakers, and a good Internet connection, you can communicate using VOIP for free. There are basically three ways of using VOIP. One is to have a PC on both communicating sides; another is to have a phone on one side and a PC on the other and the third is to have two phones. VOIP is a ly new technology and it has already achieved wide acceptance and use. There is still a lot to improve and it is expected to have major technological advances in VOIP in the future. It has so far proved to be a good candidate for replacing the POTS (Plain Old Telephone System). It, of course, has drawbacks along with the numerous advantages it brings; and its increasing use worldwide is creating new considerations surrounding its regulations and security. The growth of VOIP today can be compared to that of the Internet in the early 90's. The public is getting more and more conscious of the advantages they can get from VOIP at home or in their businesses. Advertising campaigns, which are present everywhere on the net, are contributing a lot towards the popularization of VOIP which not only gives facilities and allows people to save, but also producing huge income for those who dived early into the new phenomenon.

Options: (A) ask readers to buy the new type of production. (B) tell us how fast the modern technology is developing. (C) introduce a new type of IP technology---VOIP. (D) teach the readers how to use VOIP.

[EX Q]: Article: Why do people run? That is, why do thousands get up early and put their knees and ankles and hearts and lungs through the hell of 10,000 meters on the roads? For those who stick with it and are lucky, they get into another world: a state of physical and mental grace reached when their blood is racing through every vein . And in Austin, those who long to get better, even when they know it's impossible, hang on Gilbert's every word. Gilbert's methods are simple. It's all about form: how the arms move and the feet land. He pushes his students hard. When they feel like they're about to die, they look at Gilbert's scars -- the burns along his right arm, and then to his right leg, where the flames ate down to the bone. Whatever they feel, how bad, really, could it be? "He gets people to believe in themselves," says Lisa Spenner, one of the _ , who are crazy about Gilbert. "He treats everyone like they're amazing." If Gilbert is their savior, they are his saviors too. "Eventually, I realized I had to help people. When I help people, I feel good," he says. Gilbert's right leg was so badly burnt that the knee was stuck at a 90-degree angle. The doctor said it would take six months to heal. Frustrated, Gilbert got on a bike. The biking led to walking, which finally led to running a year after he had been left to die. In truth, runners don't race other runners. They race against themselves to conquer their wills. So Gilbert spent the spring and summer of 2007 trying to do that, racing men faster than he is, knowing it would make him better. Gilbert's students, of course, keep rooting for him, though sometimes they wonder, "How much better can he get?" After all, they see him as more than just a runner and a coach. He's a flesh-and-blood symbol: the daily struggle to show what you're made of.
Question: What do we learn about Gilbert after reading the passage?
Options: (A) He used to work as a fireman. (B) He has determination and strong will-power. (C) He learnt running from a coach. (D) He was advised to ride a bike when he was badly burnt.
[EX A]: B

[EX Q]: Article: Parents and kids today dress alike, listen to the same music, and are friends. Is this a good thing? Sometimes, when Mr. Ballmer and his 16-year-old daughter, Elizabeth, listen to rock music together and talk about interests they both enjoy, such as pop culture, he remembers his more distant relationship with his parents when he was a teenager. "I would never have said to my mom, 'Hey, the new Weezer album is really great. How do you like it?'" says Ballmer. "There was just a complete gap in taste." Music was not the only _ . From clothing and hairstyles to activities and expectations, earlier generations of parents and children often appeared to move in separate orbits. Today, the generation gap has not disappeared, but it is getting narrow in many families. Conversations on subjects such as sex and drugs would not have taken place a generation ago. Now they are comfortable and common. And parent--child activities, from shopping to sports, involve a feeling of trust and friendship that can continue into adulthood. No wonder greeting cards today carry the message, "To my mother, my best friend." But family experts warn that the new equality can also result in less respect for parents. "There's still a lot of strictness and authority on the part of parents out there, but there is a change happening," says Kerrie, a psychology professor at Lebanon Valley College. "In the middle of that change, there is a lot of confusion among parents." Family researchers offer a variety of reasons for these evolving roles and attitudes. They see the 1960s as a turning point. Great cultural changes led to more open communication and a more democratic process that encourages everyone to have a say. "My parents were on the 'before' side of that change, but today's parents, the 40-year-olds, were on the 'after' side," explains Mr. Ballmer. "It's not something easily done by parents these days, because life is more difficult to understand or deal with, but sharing interests does make it more fun to be a parent now."
Question: Which of the following shows that the generation gap is disappearing?
Options: (A) Parents help their children develop interests in more activities. (B) Parents put more trust in their children's abilities. (C) Parents and children talk more about sex and drugs. (D) Parents share more interests with their children.
