ON March 1, Canadian pop singer Justin Bieber turned 18. He celebrated the important birthday with his family and friends. In Canada, any person 18 or older can join the Canadian army and vote. Bieber also showed that he was looking forward to more independence. “18 requires (需要) a lot of responsibilities (责任),” Bieber told MTV News. “Moving out requires me to be alone, without my parents. So, legally (法律上), I can make any decision I want.” Asked what his best present was, he said, “I got a pool table (台球桌), a purple one, and it’s amazing.”21ST
