Recently, an Internet game has become a new fashion among young office workers and students. People can “farm” on a piece of “land” and “grow”, “sell” or even “steal vegetables”, “flowers” and “fruits” on the Net. They can earn some e-money and buy more “seeds”, “pets” and even “houses”.

Joyce interviewed some young people. Here are their opinions:

Harold: I don't quite understand why they are so mad about the childish game. Maybe they are just not confident enough to face the real world.

Laura: You know, people in the city are longing for(渴望)the life in the countryside. It reduces my work pressure(压力). Besides, it gives me the exciting experience of being a “thief”.
