【正确答案】 C

【答案解析】[听力原文]
With so many choices and so little time, many business people have difficulty finding comfortable and affordable hotels when they travel. However there are a few useful tips for booking a good hotel. The number one tip is to ask friends, family, or co-workers if they know of any good hotels in the city where you will be staying. If you can"t get any advice from them, go to the Internet. There you can find a variety of Web sites especially designed to help you search. However, I"d like to offer a word of warning—you must use a credit card to make advanced payment online. If you get to the hotel and find it isn"t suitable, it"s usually not possible to get your money back. So, it might be advisable to first find a few hotels online you like and then call them with a list of questions. You may want to know exactly where the hotel is located—Is the neighborhood safe at night? Are there shops and restaurants nearby? Is it on a major road where traffic will keep you awake? Having enough information may save you money in the end.
