Directions:There is a business letter here.After reading it you should give brief answers to the 5 questions(No.56 through 60
0 that follow.The answers should be written afterthe corresponding numbers.DearSir/Madam,I'm writing to you concerning a Univox CD player(Model CDP4500
)that Ipurchased several months ago from one of your dealers here in Panama City:Discount Audio.From your ads,I was led to believe that your audio equipment is the best available on the market .That"s hard to believe,considering that I"ve had nothing but problems with my CD player from the day I bought it.For one thing,the tracking mechanism doesn"twork properly:I can never tell for sure what part of the CD is playing.And now there"s a problem with the volume control:sometimes it works and sometimes it doesn"t.I took the player to the service department at Discount Audio.When I picked it up,they said they"d fixed the tracking mechanism as best they could,but it still doesn"t work properly.I"m sick and tired of all the problems I"ve had with your product.I hope you will under-stand my concern.I look forward to hearing from you about what you can do to help solve this promblem .Faithfully your,Roberto Suarez

（括号里面是我说的话,不包含在翻译里面~事先声明一下…哈哈…）
指示说明：这里有一封商业信.（我觉得第一句话的英文有点问题There is和here怎么合在一句话里面了?那里有一封信在这里…到底在哪里…）在读完它之后,你需要简答下列编号56到60的5道题目.请将答案写在对应的题号后.
亲爱的先生/女士,
我之所以写信给你是和我前几个月在你们位于巴拿马市的零售店“Discount Audio（折扣影音,或者迪斯康特影音）”买的“Univox（宥尼福克斯）”CD播放机（型号CDP4500）有关.
从你们的广告中（或者因为你们的广告）,我相信你们的影音器材是市场上最好的.现在我很难相信这一点,从我买这个CD播放机的那天开始,这个播放机除了麻烦,什么也没带给我.
其中一个问题是轨道系统不能正常运行,我都不知道CD到底在播放哪一段.现在呢,声音控制也出了问题：有时候它是好的,有时候又会坏掉.
我曾把播放机拿到“Discount Audio”的维修部门.当我去拿播放机的时候,他们说自己已经尽了最大的努力去修轨道系统了,但是它仍然不能正常运转.
我受够了你们产品带给我的困扰.我希望你能了解我的烦恼.我期待能从你那里得到如何解决这个问题的回信.
忠诚的,
罗伯特 苏尔兹
