 Thousands of people began pouring into Pennsylvania from other states. They wanted to buy lottery tickets. The tickets cost only $0.9 each .But that small spending could bring them a reward of $90 million. That was the second largest lottery jackpot(积累奖金)in history.

More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from 1 to 80. The chance of winning was one in 9.6 million. But that little chance certainly didn’t affect ticket sales. In the last few days before the drawing , tickets were selling at the unbelievable rate of 500 per second.

Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they’ll probably never have.

But many people believe lotteries are no better than legalized gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.

The profits from lotteries are usually used to pay for education or programs for senior citizens.
