阅读下列应用文及相关信息,并按照要求匹配信息。请在答题卷上作答。

首先阅读下列博客信息:

A:My name’s Marta and I’m from Mexico City, but I moved to Los Angeles, California, five years ago, now I am living in an apartment at No. 3178 SE Timmer Broad. I am 28, single. I am a customer service representative for a large financial company. I am an outgoing person. I love to laugh and have fun! I enjoy cooking, dancing and listening to music. I don’t like watching or playing sports. You should be an outgoing, considerate lady with a good sense of humor, to share the apartment. Are you the one? Email and let’s have further talk.

B: My name’s Mark, and I’m from Hollywood, California. I’m a fitness instructor in Los Angeles. I am a friendly and easy-going person; I love playing sports---especially football and working out at the gym. I also play the guitar. My best friend David, who often has sports with me, went to Mexico last month. To avoid loneliness, I’d like very much to own a new friend who would share the fun of sports with me. I am longing.

C: My name’s Park Jun Seo, but you can call me Jun. I move from Seoul Korea to Los Angeles two years ago. I am a graphic designer and I am looking for my younger brother, Lean Ban Seo, who might be in this city. As the story is too long, I just hope to find him and have my family reunited. He is lame at the right leg, 19 years old, 1.79 meters tall, with very big eyes and fair curly hair. With his picture of two years ago enclosed, I would be very appreciated if you have any information about that. Telephone me at 818-5789.

D: My name is Don and I am programmer at a computer company. I have designed several pieces of software that can help students learn better, especially suitable for primary students who have some language disability to learn words and help them pronounce more correctly. If you think you need one, please fax to 857-4693. You can purchase by post.

E: My name is Mauricio, and I’m a computer programmer working in Los Angeles area. I am kind of shy, but maybe you can help me to be more outgoing. I like cooking, playing computer games, and chatting whit friends online. If you think you are the proper one to be my E-pal, let’s chat!

F: My name’s Judy and I’m from Quebec, Canada. I am a sales woman in one of the women underwear stores in Montreal. I’d like to have more visitors to my shop. And you can bargain for a reduction of 10% to 30%, if you purchase in package. Let’s be friends.

请阅读以下网站回复的信息, 然后匹配回复的信息和网站原登出的博客信息,选项中有一项是多余的。

小题1:I am a professional sportsman and work in the same city. I am so glad that I will have a good friend who can be the opponent to improve my techniques. E-mail me at bitterflower@yahoo.com.

小题2:As a shop owner, I might drop in when I go downtown. But may I know your exact address? When is it convenient for a visit? Thank you.

小题3:God bless you! I’m a journalist and happened to read your brief story. A neighbor of mine looks exactly the same as the man in the picture you uploaded. This might be a chance in a million. Telephone me at 818-5690.

小题4:As a newcomer and a freshman, I am looking for a room as close to my university as possible. I would like to have some friends, too. I think your place might be the right choice for me. But can I know how much the rent is?
