Tara、Claudia、Monica、Terry 和Tony正在挑选自己所需要的网站。第56至60题是他们的个人情况介绍。阅读下面六个网站的简介(A、B、C、D、E、F)，选出符合各人需要的最佳选项，选项中有一项是多余选项。

56. Tara has got a new video camera and is crazy about it. Wherever she goes, she’d like to take it with her and record everything she finds interesting. She thinks it cool to share her life with others through the recordings.

57. As a newcomer to this city, Claudia wants to make new friends with people around her. She likes this city except for one thing, that is, she is not allowed to raise any pet due to the flat rules. That’s too much for an animal lover like her.

58. Monica is clever with her hands and likes making toys. She wants to find a way to show her work to others and share the pleasure with them. If possible, she’d like to make pocket money by selling the toys.

59. Terry worries about his phone bill every month. As he has lots of friends, making phone calls, sending and receiving messages are a necessary part of his life. Sometimes he has to say hello to each of his friends by mobile phone. It costs him lots of time and money.

60. In his spare time, Tony travels a lot. It’s hard for his friends to get in touch with him when he’s away. He’d like to find a way to share his travel experiences with his friends and let them know where he is.
