【答案解析】[听力原文]
W: Good evening, everyone. Welcome to the 21st annual Stern School Silent Auction and Dinner. We hope you are enjoying the evening so far. Seating for dinner will begin in thirty minutes, so you still have plenty of time to make bids on all the fine items we have up for auction. If you just came in and don"t know how to bid, please register at the table to my right and receive the auction catalog. After that, all you need to do is browse the auction items. When you see something you like, write down your name and your bid amount on the bid sheet in front of the item. And don"t forget to check back on your bid frequently to make sure you"re not being outbid. We"ll be announcing the auction winners during the dinner, so bid high and bid a lot. It"s all going to support scholarships for worthy students.
选项A正确，陈述者希望每个人“to bid high and bid a lot as it"s all going to support scholarships for worthy students”出价高，出价多，因为这些将用于资助值得资助的学生。选项B和C不是主要目的。选项D没有提及。
