Text 2 Force of habit is a powerful thing. How else can I explain why I spend $ 200 per month for a package of the Internet, TV, and telephone - most of which I don’t really need My wife and I make most calls on our cell phones. We don’t watch much TV and nearly everything we want we could get online. So why not just pay for the Internet and forget the rest. My answers are totally unreasonable: I’m 49 years old; this is how I’ve always done things; change is hard. Most of the U. S. population is in this same situation. Nielsen recently reported that although online video (视频) viewing has risen 35 percent in the past year, 99 percent of TV viewing is still done on a traditional TV. But that is not the case for younger people, like my friend Dan Frommer, a 27-year-old writer for a Website. Frommer pulled the plug (插座) on cable (有线的) TV in May 2008 and instead gets shows from the Internet by a Macintosh computer connected to his LCD television. He cannot get everthing he’d like to see, but he has saved $ 1,500 on cable-TV bills. The next generation—today’s young people—will likely never sign up for cable TV at all. This is terrible news for cable companies. For decades they have had a wonderful business model, running the tollbooth (收费站) that stood between you and the shows. Now the Internet provides a way to get around the tollbooth, and cable companies are faced with a problem: do they welcome the Internet and try to make money online, or do they fight the Internet and try to delay the damage The answer is to do both: delaying the trend with one hand while racing to develop workable Internet business models with the other. Problem is, even if the tollbooth stays up, it probably won’t make as much money. The rule is that when the Internet hits an industry, wherever you used to make dollars, you now make cents. For cable companies, the good old days may soon be over. Why do most people still watch traditional TV（）
Text 1 Two years ago, Dimas Aliprandi and Elton Plaster didn’t know of each other’s existence. Then they learned they had been switched (调换) at birth by mistake more than 20 years ago. The discovery didn’t bring bitterness. Rather, it led to the creation of a bigger family. The chain of events started with Dimas, who was always wondering why he did not look like the four sisters he grew up with. He was 14 when his doubts grew after watching a TV news report on babies getting switched at birth because of mistakes at hospitals. He wanted to do a DNA test, but it was too expensive for the family. A decade later, Dimas did it on his own. The DNA test showed that he was not the birth son of the man and woman who had raised him. The news was a shock for his parents. They at first refused to believe the results, but eventually decided to help him look for his biological parents. The search began at the Madre Regina Protmann Hospital where records were checked. The hospital searched its records and found Elton Plaster was bom there on the same day. The records led Dimas to the 35 - acre farm where Plaster lived with his parents, Nilza and Adelson, in the town of Santa Maria de Jetiba, about 30 miles from the Aliprandi home in Joao Neiva. After tests, the Plasters discovered that Elton was the biological son of the man and woman that Dimas had been calling Mom and Dad for 24 years. Meanwhile, the couple Elton had always regarded as tus biological parents were Dimas’ parents. About a year ago, Aliprandi and the parents who raised him accepted an offer from the Plasters to move to their farm, where they built a home. “This is the way it should be,” Adelson Plaster recently told Globo TV. “We are all together and I now have two sons living and working here.” Where do the Aliprandis now live（）
