IBT聽力主旨題特點：
　　在一段長演講中，通常會有兩個或以上的主要表述內容，但這些內容往往是相互關聯的，它們互相補充構成一個完整的主題。
　　出題模式：
　　IBT聽力主旨題的問題常常以特殊疑問詞開頭，例如：
　　What does announcement mainly about?
　　A: A parking garage closure in holidays.
　　B: Problems in the school’s garage.
　　C: Student activities on holidays.
　　D: Holiday emergency measures.
　　What is the subject of the conversation?
　　What aspect of ___does the professor mainly discuss?
　　What problem does the man have?
　　What are the man and the woman discussing?
　　What is the topic of the discussion?
　　What is the woman’s problem?
　　What is the lecture mainly about?
　　解題技巧：
　　在做IBT主旨題的時候一定要盡量把握文章的整體思路，可以從以下幾個方面來進行：
　　1、記住談話人語氣加重所強調的人，事物或概念。
　　2、努力把握談話或演講中的關鍵詞或短語。尤其要關注談話人不止一次提到的詞或短語。
　　3、從宏觀上把握談話或演講的內容，提煉出講話的主題。
　　舉例說明：
　　Narrator: Listen to a campus announcement and answer the question.
　　M: The East Campus Garage will be closed during the Holiday break from Thursday, December 22, 2005, 10:30 p.m. through Monday, January 2, 2005, 11:30 p.m. Please be certain to make the necessary arrangements to have your vehicle out of the garage before it closes. If you have left your vehicle in the garage after closing, please contact University Police at 8---2323, so you may exit the garage. There will be no admittance into the garage after closing. The parking office will be closed through January 2nd. Urgent messages left in voice mail or sent to the parking email account will be periodically monitored and responded to on December 27---29. All non---urgent matters will be addressed when the office re-opens on January 3, 2006. The parking gates on campus are lifted during this period and parking is available in all surface parking gates on camps are lifted during this period and parking is available in all surface parking lots except Wean and Warner Hall. Thank you for your cooperation and have a safe and happy holiday!
　　What does announcement mainly about?
　　A: A parking garage closure in holidays.
　　B: Problems in the school’s garage.
　　C: Student activities on holidays.
　　D: Holiday emergency measures.
　　解析：
　　1. 先總體把握材料提供的內容，講的是這樣的一件事：The East Campus Garage will be closed during the Holiday break from Thursday, December 22, 2005, 10:30 p.m. through Monday, January 2, 2005, 11:30 p.m.
　　2. 通過對材料的分析，可以了解到A為正確的答案。
　　3. B: Problems in the school’s garage. 答案過于精確。
　　4. C: Student activities on holidays. 過于籠統，不正確。
　　5. D: Holiday emergency measures. 過于籠統，不正確。
　　所以正確答案為A。
　　總之，在做IBT聽力主旨題的時候, 要把握住重點。排除過于籠統的答案，所表示的內容與談話或演講的核心主題脫節;和過于精確的答案，即據之一而非講述主體。還要切記排除一些似是而非的答案和在上下文中并未被談話人提及的答案。把握住這些要領，相信攻克IBT聽力主旨題不再是一件難事。
