They say drinking too much isn’t good for you, right? Now, in New York, Mayor Michael Bloomberg also limits how much soda you can have—and it is not only for you but also for adults!Starting in March, 2013, places like movie theaters, restaurants and sports centers, can’t sell sodas larger than 473 ml. Sellers who break the ban（禁令）will face a $200 fine. But you can still get whatever size you want at supermarkets.Mayor Bloomberg says it will help people keep healthy. In New York, more than half of adults and nearly 40% of the children are overweight or obese（肥胖的）. Obesity kills thousands of New Yorkers every year and the city spends as much as $4 billion a year on medical care for overweight and obese people.New York has a population of about 8 million. Of course it’s impossible for all New Yorkers to agree on the ban. There are different opinions（意见）. Keith Aiken believes the ban can help fight teen obesity. “Clearly, soda causes teen obesity. We have to do something,” he says. Chuck Kallenbach doesn’t think the ban can work. He says, “I can’t buy a large cup of soda, but I can buy two small cups.” Michael Tansini says, “Whatever size cup I want is my own business. No one should limit it!”1.This passage is mainly written for .A.teenagers B.adults C.teachers D.sellers2.Where can one get sodas larger than 473 ml in New York after March, 2013?A.At movie theaters. B.At restaurants.C.At sports centers. D.At supermarkets.3.Who are against the ban?A.Michael Bloomberg and Chuck Kallenbach. B.Michael Bloomberg and Keith Aiken.C.Chuck Kallenbach and Michael Tansini. D.Keith Aiken and Michael Tansini.4.Which of the following is TRUE according to the passage?A.New York is a city with about 80,000,000 people.B.Over half of the children are overweight or obese in New York.C.Nearly 40% of the New Yorkers are against the large-size soda ban.D.Thousands of New Yorkers lost their lives every year because of obesity.
